Deriving meteorological variables across Africa for the study and control of vector-borne disease: a comparison of remote sensing and spatial interpolation of climate. (1/247)

This paper presents the results of an investigation into the utility of remote sensing (RS) using meteorological satellites sensors and spatial interpolation (SI) of data from meteorological stations, for the prediction of spatial variation in monthly climate across continental Africa in 1990. Information from the Advanced Very High Resolution Radiometer (AVHRR) of the National Oceanic and Atmospheric Administration's (NOAA) polar-orbiting meteorological satellites was used to estimate land surface temperature (LST) and atmospheric moisture. Cold cloud duration (CCD) data derived from the High Resolution Radiometer (HRR) on-board the European Meteorological Satellite programme's (EUMETSAT) Meteosat satellite series were also used as a RS proxy measurement of rainfall. Temperature, atmospheric moisture and rainfall surfaces were independently derived from SI of measurements from the World Meteorological Organization (WMO) member stations of Africa. These meteorological station data were then used to test the accuracy of each methodology, so that the appropriateness of the two techniques for epidemiological research could be compared. SI was a more accurate predictor of temperature, whereas RS provided a better surrogate for rainfall; both were equally accurate at predicting atmospheric moisture. The implications of these results for mapping short and long-term climate change and hence their potential for the study and control of disease vectors are considered. Taking into account logistic and analytical problems, there were no clear conclusions regarding the optimality of either technique, but there was considerable potential for synergy.  (+info)

Protein kinetics during and after long-duration spaceflight on MIR. (2/247)

Human spaceflight is associated with a loss of body protein. Bed rest studies suggest that the reduction in the whole body protein synthesis (PS) rate should be approximately 15%. The objectives of this experiment were to test two hypotheses on astronauts and cosmonauts during long-duration (>3 mo) flights on MIR: that 1) the whole body PS rate will be reduced and 2) dietary intake and the PS rate should be increased postflight because protein accretion is occurring. The 15N glycine method was used for measuring whole body PS rate before, during, and after long-duration spaceflight on the Russian space station MIR. Dietary intake was measured together with the protein kinetics. Results show that subjects lost weight during flight (4.64 +/- 1.0 kg, P < 0.05). Energy intake was decreased inflight (2,854 +/- 268 vs. 2,145 +/- 190 kcal/day, n = 6, P < 0.05), as was the PS rate (226 +/- 24 vs. 97 +/- 11 g protein/day, n = 6, P < 0.01). The reduction in PS correlated with the reduction in energy intake (r2 = 0.86, P < 0.01, n = 6). Postflight energy intake and PS returned to, but were not increased over, the preflight levels. We conclude that the reduction in PS found was greater than predicted from ground-based bed rest experiments because of the shortfall in dietary intake. The expected postflight anabolic state with increases in dietary intake and PS did not occur during the first 2 wk after landing.  (+info)

Identifying populations potentially exposed to agricultural pesticides using remote sensing and a Geographic Information System. (3/247)

Pesticides used in agriculture may cause adverse health effects among the population living near agricultural areas. However, identifying the populations most likely to be exposed is difficult. We conducted a feasibility study to determine whether satellite imagery could be used to reconstruct historical crop patterns. We used historical Farm Service Agency records as a source of ground reference data to classify a late summer 1984 satellite image into crop species in a three-county area in south central Nebraska. Residences from a population-based epidemiologic study of non-Hodgkin lymphoma were located on the crop maps using a geographic information system (GIS). Corn, soybeans, sorghum, and alfalfa were the major crops grown in the study area. Eighty-five percent of residences could be located, and of these 22% had one of the four major crops within 500 m of the residence, an intermediate distance for the range of drift effects from pesticides applied in agriculture. We determined the proximity of residences to specific crop species and calculated crop-specific probabilities of pesticide use based on available data. This feasibility study demonstrated that remote sensing data and historical records on crop location can be used to create historical crop maps. The crop pesticides that were likely to have been applied can be estimated when information about crop-specific pesticide use is available. Using a GIS, zones of potential exposure to agricultural pesticides and proximity measures can be determined for residences in a study.  (+info)

A close-up look at Io from Galileo's near-infrared mapping spectrometer. (4/247)

Infrared spectral images of Jupiter's volcanic moon Io, acquired during the October and November 1999 and February 2000 flybys of the Galileo spacecraft, were used to study the thermal structure and sulfur dioxide distribution of active volcanoes. Loki Patera, the solar system's most powerful known volcano, exhibits large expanses of dark, cooling lava on its caldera floor. Prometheus, the site of long-lived plume activity, has two major areas of thermal emission, which support ideas of plume migration. Sulfur dioxide deposits were mapped at local scales and show a more complex relationship to surface colors than previously thought, indicating the presence of other sulfur compounds.  (+info)

Prometheus: Io's wandering plume. (5/247)

Unlike any volcanic behavior ever observed on Earth, the plume from Prometheus on Io has wandered 75 to 95 kilometers west over the last 20 years since it was first discovered by Voyager and more recently observed by Galileo. Despite the source motion, the geometric and optical properties of the plume have remained constant. We propose that this can be explained by vaporization of a sulfur dioxide and/or sulfur "snowfield" over which a lava flow is moving. Eruption of a boundary-layer slurry through a rootless conduit with sonic conditions at the intake of the melted snow can account for the constancy of plume properties.  (+info)

Discovery of gaseous S2 in Io's Pele plume. (6/247)

Spectroscopy of Io's Pele plume against Jupiter by the Hubble Space Telescope in October 1999 revealed absorption due to S2 gas, with a column density of 1.0 +/- 0.2 x 10(16) per square centimeter, and probably also SO(2) gas with a column density of 7 +/- 3 x 10(16) per square centimeter. This SO2/S2 ratio (3 to 12) is expected from equilibration with silicate magmas near the quartz-fayalite-magnetite or wustite-magnetite buffers. Condensed S3 and S4, probable coloring agents in Pele's red plume deposits, may form by polymerization of the S2, which is unstable to ultraviolet photolysis. Diffuse red deposits near other Io volcanoes suggest that venting and polymerization of S2 gas is a widespread feature of Io volcanism.  (+info)

Biospheric primary production during an ENSO transition. (7/247)

The Sea-viewing Wide Field-of-view Sensor (SeaWiFS) provides global monthly measurements of both oceanic phytoplankton chlorophyll biomass and light harvesting by land plants. These measurements allowed the comparison of simultaneous ocean and land net primary production (NPP) responses to a major El Nino to La Nina transition. Between September 1997 and August 2000, biospheric NPP varied by 6 petagrams of carbon per year (from 111 to 117 petagrams of carbon per year). Increases in ocean NPP were pronounced in tropical regions where El Nino-Southern Oscillation (ENSO) impacts on upwelling and nutrient availability were greatest. Globally, land NPP did not exhibit a clear ENSO response, although regional changes were substantial.  (+info)

Mass spectrometry in the U.S. space program: past, present, and future. (8/247)

Recent years have witnessed significant progress on the miniaturization of mass spectrometers for a variety of field applications. This article describes the development and application of mass spectrometry (MS) instrumentation to support of goals of the U.S. space program. Its main focus is on the two most common space-related applications of MS: studying the composition of planetary atmospheres and monitoring air quality on manned space missions. Both sets of applications present special requirements in terms of analytical performance (sensitivity, selectivity, speed, etc.), logistical considerations (space, weight, and power requirements), and deployment in perhaps the harshest of all possible environments (space). The MS instruments deployed on the Pioneer Venus and Mars Viking Lander missions are reviewed for the purposes of illustrating the unique features of the sample introduction systems, mass analyzers, and vacuum systems, and for presenting their specifications which are impressive even by today's standards. The various approaches for monitoring volatile organic compounds (VOCs) in cabin atmospheres are also reviewed. In the past, ground-based GC/MS instruments have been used to identify and quantify VOCs in archival samples collected during the Mercury, Apollo, Skylab, Space Shuttle, and Mir missions. Some of the data from the more recent missions are provided to illustrate the composition data obtained and to underscore the need for instrumentation to perform such monitoring in situ. Lastly, the development of two emerging technologies, Direct Sampling Ion Trap Mass Spectrometry (DSITMS) and GC/Ion Mobility Spectrometry (GC/IMS), will be discussed to illustrate their potential utility for future missions.  (+info)

Impact of assembly, testing and launch operations on the airborne bacterial diversity within a spacecraft assembly facility clean-room - Volume 7 Issue 3-4 - David A. Newcombe, Myron T. La Duc, Parag Vaishampayan, Kasthuri Venkateswaran
A spacecraft is a vehicle that can carry people and cargo beyond the Earths atmosphere, through space to other planetary bodies, space stations, or orbits and back home again. Spacecraft which are launched from the surface of a planet are called launch vehicles and usually take-off from launch pads at spaceports.. Most spacecraft today are propelled by rocket engines, which shoot hot gases opposite to the direction of travel. Other forms of propulsion are used when appropriate. Spacecraft which do not need to escape from strong gravity may use ion thrusters or other more efficient methods.. Because of the very large amount of energy needed to leave the Earths gravity, spacecraft are usually very expensive to build, launch, and operate. Plans for future spacecraft often focus on reducing these costs so more people can participate in space. But today, costs are still very high, and until recently all spacecraft were sponsored by national governments.. ...
Bacillus strains producing highly resistant spores have been isolated from cleanrooms and space craft assembly facilities. Organisms that can survive such conditions merit planetary protection concern and if that resistance can be transferred to other organisms, a health concern too. To further efforts to understand these resistances, the complete genome of Bacillus safensis strain FO-36b, which produces spores resistant to peroxide and radiation was determined. The genome was compared to the complete genome of B. pumilus SAFR-032, and the draft genomes of B. safensis JPL-MERTA-8-2 and the type strain B. pumilus ATCC7061T. Additional comparisons were made to 61 draft genomes that have been mostly identified as strains of B. pumilus or B. safensis. The FO-36b gene order is essentially the same as that in SAFR-032 and other B. pumilus strains. The annotated genome has 3850 open reading frames and 40 noncoding RNAs and riboswitches. Of these, 307 are not shared by SAFR-032, and 65 are also not shared by
A fractionated spacecraft is a satellite architecture for which the functional capabilities of a conventional spacecraft are distributed across multiple modules (spacecrafts) which fly separately and interact through wireless links. Removing the physical dependencies between the resources, or subsystems, of a spacecraft, brings several attributes, such as flexibility and robustness, which can be exploited for the benefit of the earth observation payloads. In this manner, an infrastructure network which is composed of resource modules can be put into a sun-synchronous orbit for the benefit of such payloads. However, fractionating a spacecraft and letting the different subsystems fly separately leads to several technological concerns which are related to the shared resources within the fractionated spacecraft network. Regarding these technology implications, collision free close proximity cluster flying configurations were evaluated initially. Then a realization approaches were also discussed via ...

The Jet Propulsion Laboratory, in conjunction with the NASA Planetary Protection Officer, has selected the vapor phase hydrogen peroxide sterilization process for continued development as a NASA approved sterilization technique for spacecraft subsystems and systems. The goal is to include this technique, with an appropriate specification, in NPR 8020.12C as a low temperature complementary technique to the dry heat sterilization process.To meet microbial reduction requirements for all Mars in-situ life detection and sample return missions, various planetary spacecraft subsystems will have to be exposed to a qualified sterilization process. This process could be the elevated temperature dry heat sterilization process (~115 C for 40 hours) which was used to sterilize the Viking lander spacecraft. However, with utilization of such elements as highly sophisticated electronics and sensors in modern spacecraft, this process presents significant materials challenges and is thus an undesirable bioburden

Traditionally, Direct Energy (DE), especially High Energy Laser (HEL), has mainly been considered for beaming energy or power, however, it can be exploited for beaming momentum as well. Dr. Y. K . Bae presents an innovative spacecraft maneuvering architecture, DE Momentum Beaming (DEMB), in which momentum is beamed between two spacecraft platforms via the pressure of circulating photons between them with the use of recently developed Photonic Laser Thruster (PLT). Many advanced DoD in-space missions need a wider range of dynamic spacecraft maneuvers than formation flying. Conventional spacecraft maneuvering is performed by momentum applied to a single vehicle by exhausting fuel in forms of plumb or ions, which limits lifetime and delta-V capability. Through momentum beaming, DEMB will drastically reduce the fuel consumption or separate the highly valuable mission vehicle from a lower-cost, replaceable resource vehicle (similar to aerial refueling) to lower the life-cycle cost significantly in a ...
In the design of spacecraft, heat transfer becomes a criterion of operation to maintain structural and equipment integrity over long periods of time. The spacecraft thermal balance between cold space and solar, planetary, and equipment heat sources is the means by which the desired range of equipment and structural temperatures are obtained. With the total spacecraft balance set, subsystem and component temperatures can be analyzed for their corresponding thermal requirements. This section provides the means by which first-cut approximations of spacecraft surface, structure, and equipment temperatures may be made, using the curves of planetary and solar heat flux in conjunction with the desired coating radiative properties. Once the coating properties have been determined, the material to provide these requirements may be selected from the extensive thermal radiative properties tables and curves. These can then be cross checked to determine the degradation effects of space that may cause ...

A key challenge in operating remote spacecraft is that ground operators must rely on the limited visibility available through spacecraft telemetry in order to assess spacecraft health and operational status. We describe a tool for processing spacecraft telemetry that allows ground operators to impose structure on received telemetry in order to achieve a better comprehension of system state. A key element of our approach is the design of a domain-specific language that allows operators to express models of expected system behavior using partial specifications. The language allows behavior specifications with data fields, similar to other recent runtime verification systems. What is notable about our approach is the ability to develop hierarchical specifications of behavior. The language is implemented as an internal DSL in the Scala programming language that synthesizes rules from patterns of specification behavior. The rules are automatically applied to received telemetry and the inferred ...
WOODLAND HILLS, Calif., May 9, 2011 (GLOBE NEWSWIRE) -- Northrop Grumman Corporations (NYSE:NOC) space navigation aid recently provided key guidance and control information that allowed NASAs MESSENGER to become the first spacecraft to successfully orbit Mercury, marking the culmination of a more-than six-year, 4.9 billion-mile journey to the innermost planet.. The MESSENGER spacecraft utilizes Northrop Grummans Scalable Space Inertial Reference Unit (Scalable SIRU™), an inertial reference system that supplies critical rotation rate data that enable the stabilization, pointing, and attitude control of satellites and space vehicles.. Mercury has been relatively unexplored, in part because of challenges to slowing down a spacecraft sufficiently to enter orbit. This is where the Scalable SIRU™ made a critical difference. As the sole governing sensor during the Mercury orbit insertion maneuver, the Scalable SIRU™ provided precise navigation information to guide the spacecraft into a ...
When in space, the purpose of a propulsion system is to change the velocity, or v, of a spacecraft. Because this is more difficult for more massive spacecrafts, designers generally discuss spacecraft performance in amount of change in momentum per unit of propellant consumed also called specific impulse.[9] Higher the specific impulse, better the efficiency. Ion propulsion engines have high specific impulse (~3000 s) and low thrust[10] whereas chemical rockets like monopropellant or bipropellant rocket engines have a low specific impulse (~300 s) but high thrust[11]. When launching a spacecraft from Earth, a propulsion method must overcome a higher gravitational pull to provide a positive net acceleration.[12] In orbit, any additional impulse, even very tiny, will result in a change in the orbit path. The rate of change of velocity is called acceleration, and the rate of change of momentum is called force. To reach a given velocity, one can apply a small acceleration over a long period of time, ...

Sentinel-2 is planned for launch in 2014 by the European Space Agency and it is equipped with the Multi Spectral Instrument (MSI), which will provide images with high spatial, spectral and temporal resolution. It covers the VNIR/SWIR spectral region in 13 bands and incorporates two new spectral bands in the red-edge region, which can be used to derive vegetation indices using red-edge bands in their formulation. These are particularly suitable for estimating canopy chlorophyll and nitrogen (N) content. This band setting is important for vegetation studies and is very similar to the ones of the Ocean and Land Colour Instrument (OLCI) on the planned Sentinel-3 satellite and the Medium Resolution Imaging Spectrometer (MERIS) on Envisat, which operated from 2002 to early 2012.

UNIVERSITY OF ARIZONA PRESS RELEASE. We’ve all heard about the space missions that are DOA when NASA engineers lose touch with the spacecraft or lander. In other cases, some critical system fails and the mission is compromised.. Both are maddening scenarios because the spacecraft probably could be easily fixed if engineers could just get their hands on the hardware for a few minutes.. Ali Akoglu and his students at The University of Arizona are working on hybrid hardware/software systems that one day might use machine intelligence to allow the spacecraft to heal themselves.. Akoglu, an assistant professor in electrical and computer engineering, is using Field Programmable Gate Arrays, or FPGA, to build these self-healing systems. FPGAs combine software and hardware to produce flexible systems that can be reconfigured at the chip level.. Because some of the hardware functions are carried out at the chip level, the software can be set up to mimic hardware. In this way, the FPGA ...
HAMPTON, Va. (AP) - NASA says it has completed final testing of the water impact of the Orion spacecraft at its Langley Research Center in Hampton.The space agency says it recently completed the testing of the impact of an 18,000-pound test version of the spacecraft in the same facility where Apollo astronauts trained for moonwalks.Officials say swing and drop testing began last summer to certify the Orion spacecraft for water landings. The next round of water impact testing is scheduled
The spacecraft weighs 2,120 Kilograms and is 9.9 by 16.5 by 3.7 meters in size when fully deployed on orbit.

Degree granting institution Delft University of Technology. Date 2018-01-26. Abstract Nitrogen oxides (NOx) are important air pollutants and play a crucial role in climate change. NOx emissions are important for chemical transport models to simulate and forecast air quality. Up-to-date emission information also helps policymakers to mitigate air pollution. In this thesis, we have focused on providing better NOx emission estimates with the DECSO (Daily Emission estimates Constrained by Satellite Observations) inversion algorithm applied to satellite observations. DECSO is a fast algorithm, which enables daily emissions estimates as soon as the satellite observations are available. Satellite-derived emissions reveal more specific information on the location and strength of sources than concentration observations. The monthly and yearly variability in emissions are well captured. This is demonstrated by our monitoring of the effect of air quality regulations on emissions during events like the 2014 ...

Lead Center: ARC OCT Technology Area: TA08 Advancements in supporting spacecraft technologies are making small spacecraft more and more capable. Features such as extensive computing power, attitude determination and control systems, and even propulsion are allowing mission designers to consider small and very small spacecraft to perform operational and scientific investigations. However, one area that is lagging is the miniaturization of instrument systems that would be compatible with this new class of small spacecraft. Until science instruments can be downsized in order for them to be accommodated on small spacecraft, the utility of cubesats, nanosats, and mini-spacecraft platforms will be limited. To stimulate and create scientific instrument technologies that are compatible with small spacecraft, this subtopic seeks to identify, develop, and prepare for flight demonstration, scientific instruments compatible with one or more of the small spacecraft platforms described at the end of this ...
A multiple access communications system comprises a node spacecraft GEO and several user spacecraft LEO1 to LEOn. Each user spacecraft LEO1 to LEOn includes a transmit/receive terminal head 181 to 18n, and the node spacecraft GEO includes n transmit/terminals 22 to 22n and a single beacon unit 24. The beacon beam may be operated to initiate acquisition phases which allow two-way communication to be established between the transmit/receive terminals 221 to 22n on the node spacecraft and the transmit/receive terminals 181 to 18n on the corresponding user terminals. The acquisition phases include a period during which the beacon scans an uncertainty cone associated with the node spacecraft. This scanning period is reduced for second and subseqeunt acquisitions by using the first and subsequently acquired communication links to provide a more accurate estimate of the angular attitude of the node spacecraft, thus reducing the extent of the uncertainty cone.

Y1 - 2020/4/27. N2 - Estuaries act as transitional areas on the coastal zone that connect highly saline ocean environments with fresh river systems. This dynamic aquatic ecosystem is created by deep fluctuations in water quality and salinity levels. Cilamaya estuary supports a highly diverse marine ecosystem that is underutilized due to knowledge deficiencies of its variable rates of salinity. The aim of this study is to show the difference zone of estuary based on the sea surface salinity in the different time, so that Cilamaya Estuary areas can be utilized optimally for resource management. Sea surface salinity is obtained using algorithmic calculations based on the Sentinel-2A imagery. Salinity levels are studied based on the rainy and dry seasons. The higher salinity occur on the dry seasons, while on the ...
The Gonets-M satellite provides a total of 16 communication channels - 14 (13+1) uplink channels and two downlink channels with no space-to-space capability. Communications are supported in frequency ranges of 260MHz and 312-390MHz - typically, uplink is provided at data rates of 2.4 to 9.6Kb/sec while downlink is provided at data rates of 4.8 to 6.4Kb/sec. Data can be stored in an 8MB onboard memory.. For beam accuracy, Gonets-M uses the Russian GLONASS positioning satellite system with a user position accuracy of 100 meters to allow it to target the desired ground stations for data downlink. The daily data throughput for each spacecraft is expected to be at least 270Mbit with a typical message length of up to 500Kbits and a nominal transfer time of under two minutes per message. The satellites have a life expectancy of five years.. The next generation of Gonets satellites known as Gonets-M1 will be introduced in the coming years utilizing a completely new and more powerful spacecraft bus with ...

Another day, another spacecraft plummeting to Earth. No biggie.. At least, thats what authorities are saying about the anticipated crash-landing of the Russian Phobos-Grunt probe, which will likely litter the Earth with debris January 14 or 15.. The probe was once a crowning jewel of the Russian space-exploration industry. It launched in 2011 to land on Mars moon Phobos and collect rock samples, but failed to launch into the missions planned trajectory.. The spacecraft was stranded in Earths orbit after its engines failed, meaning a nearly-full load of toxic rocket fuel is still on board.. Now, its just a guessing game for those interested in following space junk.. Roughly 20 or 30 fragments of the probe are expected to strike the Earths surface next month, weighing around 400 pounds. As in the past, most pieces will probably crash into oceans or undeveloped land.. But some say thats no reason to shrug off the failed attempt at space exploration.. Andrea Gini, founder of the Space Safety ...

Engineers and technicians have completed their careful work in preparing the Orion spacecraft for launch and the time has come to move the next generation spaceship to the launch pad to United Launch Alliances waiting Delta IV-Heavy rocket. The move is the latest major milestone ahead of the launch of this first flight test which will be flown without a crew. The mission was designed to make sure the spacecraft and heat shield can handle the stresses envisioned for future flights that call for Orion to safely take astronauts beyond low Earth orbit to deep space destinations including asteroids. Orion is a vital element in NASAs plan to eventually send astronauts on a journey to Mars.. Tonight though, Orions trip is confined to NASAs Kennedy Space Center and Cape Canaveral Air Force Station. A news briefing at 4:30 p.m. ET will precede the move and include comments from Bob Cabana, director of Kennedy, Ellen Ochoa, director of NASAs Johnson Space Center, Mark Geyer, Orions program manager, ...

Text by Kassandra Bucher. Over the past decade, Europes Rosetta spacecraft has been traveling toward a rendezvous with the comet 67P/Churyumov-Gerasimenko. It reached its destination in August and has been studying the gasses and dust near the comet, searching for clues about the history of the heavens and the origins of life on Earth.. But on November 12, the spacecraft is poised to deliver its payload and attempt the first-ever soft landing on a comet with Philae, its lander. To mark this historic event, swissnex San Francisco and the Chabot Space & Science Center host a live feed in Chabots full dome planetarium beginning.. On hand remotely will be scientist Kathrin Altwegg of the University of Bern, Switzerland, who leads the Rosina experiment, the two big mass spectrometers aboard Rosetta. She will be watching the landing from the European Space Agencys mission control center and talk with us via a live feed. Heres what she has to say about why this mission is so thrilling and why you ...
Since December 2004, when Voyager 1 crossed a point in space called the termination shock, the spacecraft has been exploring the heliospheres outer layer, called the heliosheath. In this region, the stream of charged particles from the sun, known as the solar wind, abruptly slowed down from supersonic speeds and became turbulent. Voyager 1s environment was consistent for about five and a half years. The spacecraft then detected that the outward speed of the solar wind slowed to zero.. The intensity of the magnetic field also began to increase at that time.. Voyager data from two onboard instruments that measure charged particles showed the spacecraft first entered this magnetic highway region on July 28, 2012. The region ebbed away and flowed toward Voyager 1 several times. The spacecraft entered the region again Aug. 25 and the environment has been stable since.. If we were judging by the charged particle data alone, I would have thought we were outside the heliosphere, said Stamatios ...
We discuss spacecraft Doppler tracking for detecting gravitational waves in which Doppler data recorded on the ground are linearly combined with Doppler measurements made on board a spacecraft. By using the four-link radio system first proposed by Vessot and Levine, we derive a new method for removing from the combined data the frequency fluctuations due to the Earth troposphere, ionosphere, and mechanical vibrations of the antenna on the ground ...
The Deep Space 1 spacecraft was launched in 1998. It tested twelve new space exploration technologies, including a new propulsion system. In testing the new equipment, it flew past the Near-Earth Asteroid Braille. The mission was then extended to include a fly-by of Comet Borrelly in September 2001. It took the best images ever taken of a comet. The Deep Space 1 mission officially ended on December 18, 2001, but the mission was certainly a great success! Has the Yohkoh spacecraft mission also come to an end? Well have to wait and see! On December 14, 2001, the Japanese spacecraft experienced a power shutdown to the science instruments. This power shutdown was triggered by an eclipse of the Sun that occurred over parts of the Pacific Ocean that same day. Efforts are being made to recover the spacecraft. The Yohkoh spacecraft was launched in 1991 and will be considered a great success even if the spacecraft cant be recovered. Yohkoh was especially well known for providing real-time monitoring of ...

The forepart of the spacecraft is the orbital module (Russian: бытовой отсек, romanized: bytovoi otsek), also known as habitation section. It houses all the equipment that will not be needed for reentry, such as experiments, cameras or cargo. The module also contains a toilet, docking avionics and communications gear. Internal volume is 6 m3 (212 cu ft), living space 5 m3 (177 cu ft). On the latest Soyuz versions (since Soyuz TM), a small window was introduced, providing the crew with a forward view. A hatch between it and the descent module can be closed so as to isolate it to act as an airlock if needed, crew members exiting through its side port (near the descent module). On the launch pad, the crew enter the spacecraft through this port. This separation also lets the orbital module be customized to the mission with less risk to the life-critical descent module. The convention of orientation in a micro-g environment differs from that of the descent module, as crew members stand or ...
This newly released Cassini image shows Saturn and its moon Titan.. Titan and Saturn have very few things in common, but a hazy appearance is one feature they share. Though they appear similar in this image, appearances can be misleading.. Although both Saturn and Titan (3,200 miles or 5,150 kilometers across) have thick atmospheres and are covered in clouds, their differences are significant. Saturn is a gas giant with no solid surface to speak of. Titans atmosphere is a blanket surrounding an icy, solid body. Even their atmospheric compositions are different; Saturn is mostly hydrogen and helium with clouds of water and ammonia and ammonium hydrosulfide. Titans atmosphere is primarily nitrogen with methane clouds.. This view looks toward Saturn from the unilluminated side of the rings, 0.3 degrees below the ring plane. The image was taken in visible green light with the Cassini spacecraft wide-angle camera on May 22, 2015.. The view was obtained at a distance of approximately 1.4 million ...
Consider it a cosmic carousel with countless rings up for grabs.. NASAs Saturn-orbiting spacecraft, Cassini, has begun an unprecedented mission to skim the planets rings. On Tuesday, Cassini got a gravitational assist from Saturns big moon Titan. That put the spacecraft on course to graze Saturns main outer rings over the next five months.. The first orbit of this new venture begins Wednesday night. Then on Sunday, an engine firing by Cassini should seal the deal, with the spacecraft making its first ring crossing.. The probes orbit will graze those signature bands once every seven days from now until April, analyzing the milky bands around the planet along the way.. Those bands around Saturn are actually made of countless ice and rock particles swirling in space. There are even moon that orbit within the rings and smaller chunks that spin like propellors, clearing the debris around them.. You can kind of think of Saturns main ring disc as kind of like what the solar system might have ...
Enceladus (/ɛnˈsɛlədəs/; en-SEL-ə-dəs) is the sixth-largest moon of Saturn. It is about 500 kilometers (310 mi) in diameter, about a tenth of that of Saturns largest moon, Titan. Enceladus is mostly covered by fresh, clean ice, making it one of the most reflective bodies of the Solar System. Consequently, its surface temperature at noon only reaches −198 °C (−324 °F), far colder than a light-absorbing body would be. Despite its small size, Enceladus has a wide range of surface features, ranging from old, heavily cratered regions to young, tectonically deformed terrains that formed as recently as 100 million years ago. Enceladus was discovered on August 28, 1789, by William Herschel, but little was known about it until the two Voyager spacecraft, Voyager 1 and Voyager 2, passed nearby in the early 1980s. In 2005, the Cassini spacecraft started multiple close flybys of Enceladus, revealing its surface and environment in greater detail. In particular, Cassini discovered water-rich ...

Data collected during two close flybys of Saturns moon Enceladus by NASAs Cassini spacecraft add more fuel to the fire about the Saturnian ice world containing sub-surface liquid water. The data collected by Cassinis Ion and Neutral Mass Spectrometer during Enceladus flybys in July and Oct. 2008, were released in the July 23 issue of the journal Nature. When Cassini flew through the plume erupting from Enceladus on October 8 of last year, our spectrometer was able to sniff out many complex chemicals, including organic ones, in the vapor and icy particles, said Hunter Waite, the Cassini Ion and Neutral Mass Spectrometer Lead Scientist from the Southwest Research Institute in San Antonio, Texas. One of the chemicals definitively identified was ammonia ...
The research and improvement of methods to be used for crop monitoring are currently major challenges, especially for radar images due to their speckle noise nature. The European Space Agency’s (ESA) Sentinel-1 constellation provides synthetic aperture radar (SAR) images coverage with a 6-day revisit period at a high spatial resolution of pixel spacing of 20 m. Sentinel-1 data are considerably useful, as they provide valuable information of the vegetation cover. The objective of this work is to study the capabilities of multitemporal radar images for rice height and dry biomass retrievals using Sentinel-1 data. To do this, we train Sentinel-1 data against ground measurements with classical machine learning techniques (Multiple Linear Regression (MLR), Support Vector Regression (SVR) and Random Forest (RF)) to estimate rice height and dry biomass. The study is carried out on a multitemporal Sentinel-1 dataset acquired from May 2017 to September 2017 over the Camargue region, southern France. The
CAPE CANAVERAL, Fla. (AP) -- NASA's Cassini spacecraft faces one last perilous adventure around Saturn. Early Saturday, Cassini
Saturn is almost twice as far from the Sun as Jupiter at nearly 900 million miles. It is second in size in our solar system, surpassed only by Jupiter, but Saturns mass is much smaller. Saturns specific gravity is less than waters, meaning it would float on a body of water! Like Jupiter, Saturn rotates extremely fast, and completes a rotation in about 10 hours. It takes a little over 29 years to make one revolution around the Sun. Saturn has 60 confirmed satellites, many of which are buried inside Saturns smaller ring systems which are being discovered by NASAs Cassini spacecraft. It is very difficult for astronomers to count the number of moons revolving around Saturn, because it is difficult to distinguish between tiny moons and the numerous ice chunks composing Saturns smaller ringlets. The large moon Titan is the most interesting in terms of atmospheric composition (mentioned below). It is likely more satellites will be found in the future when astronomers diagnose Saturns small, thin ...
I have some thoughts about planetary protection.. 1) As long as humans are kept off of Mars it impedes the discovery of fossil life. Fossil life would be a very important scientific discovery.. 2) Infection concerns. Earth,Mars, or Mars,Earth. I suppose we could argue that no risks should be taken, but if no risks are ever taken, then it may be very hard to confirm a discovery of a existing living life form on Mars.. One piece of evidence I can give already is this. For planets around other stars, an indicator of the non-existence of life is said to be the presence of Carbon Monoxide. Well, Mars, has Carbon Monoxide, and twice that of Oxygen. If there is a life form, then there is not enough of it to consume the Carbon Monoxide.. I have some additional patience, for NASA and others to send probes, but I want to be sure that this is not ploy to hold the human race back. There are thing to suspicious about.. For instance, diverting the American space program from the Moon to Mars, then to a tiny ...
After 20 years, nearly 300 orbits and pioneering discoveries, the Cassini spacecraft plunges to its death in Saturns atmosphere - taking data until its very last breath.
Odyssey was launched April 7 from Cape Canaveral Air Force Station, Florida. Other than our Moon, Mars has attracted more spacecraft exploration attempts than any other object in the solar system, and no other planet has proved as daunting to success. Of the 30 missions sent to Mars by three countries over 40 years, less than one-third have been successful. The spacecraft, ground system and flight team are ready for Mars orbit insertion, said Matthew Landano, Odyssey project manager at NASAs Jet Propulsion Laboratory, Pasadena, California. We uplinked the sequence of commands that control the orbit insertion on October 15. Now we will closely monitor the spacecrafts progress as it approaches Mars and executes the orbit insertion burn.. ...
Two days before plunging into Saturn, the Cassini spacecraft took one last look around the planet it had orbited for more than 13 years.. The view of Saturn above, released November 21, is actually made from 42 images that have been stitched together. Six moons - Enceladus, Epimetheus, Janus, Mimas, Pandora and Prometheus - are faintly visible as dots surrounding the gas giant (see the annotated image below). Cassini was about 1.1 million kilometers away from Saturn when it took the images on September 13. The whole observation took a little over two hours.. On September 11, Cassini set itself on a collision course with Saturn, and on September 15, the probe ended its mission by burning up in Saturns atmosphere, taking data all the way down.. ...
NASAs Cassini spacecraft will wrap up its time in the region of Saturns large, icy moons with a series of three close encounters with Enceladus starting Wednesday, Oct. 14. Images are expected to begin arriving one to two days after the flyby, which will provide the first opportunity for a close-up look at the north polar region of Enceladus.
The celestial bodies have long been mere sources of beauty and rapture for the human race. However, thanks to advancements in technology such as the Cassini probe, much more value can now be received from bodies such as Enceladus, especially its plumes.. Although some scientists have guessed that the tidal heating occurring on Enceladus due to Saturns immense gravity have caused geysers to form, when calculated, the heat produced by tidal heating is not enough to create geysers. This means that there is a mysterious source of heat heating up in the interior of the Enceladus to create its plumes. Focusing the Cassini probe on Enceladus may give us a better clue on what exactly is heating the moon, or may instead, confound us, meaning that we have discovered a heating mechanism previously unseen. Either way, the Cassini probe will be able to shed some light on what exactly causes the Enceladus plumes. There are no guarantees about what the Cassini probe may find, but the uncertainty makes it all ...
NASAs Juno mission completed a close flyby of Jupiter and its Great Red Spot on July 10, during its sixth science orbit.. All of Junos science instruments and the spacecrafts JunoCam were operating during the flyby, collecting data that are now being returned to Earth. Junos next close flyby of Jupiter will occur on Sept. 1.. Raw images from the spacecrafts latest flyby will be posted in coming days.. For generations people from all over the world and all walks of life have marveled over the Great Red Spot, said Scott Bolton, principal investigator of Juno from the Southwest Research Institute in San Antonio. Now we are finally going to see what this storm looks like up close and personal.. The Great Red Spot is a 10,000-mile-wide (16,000-kilometer-wide) storm that has been monitored since 1830 and has possibly existed for more than 350 years. In modern times, the Great Red Spot has appeared to be shrinking. Juno reached perijove (the point at which an orbit comes closest to Jupiters ...
Spacecraft Operations Team Manager, NASAs Cassini spacecraft. On Sunday evening, my eyes were glued to eight windows on my computer screen, watching data pop up every few seconds. NASAs Cassini spacecraft was making its lowest swing through the atmosphere of Saturns moon Titan and I was on the edge of my seat. Trina Ray, a Titan orbiter science team co-chair, was keeping me company. Five other members of my team were also at JPL. Between us, we were keeping an eye on about 2,000 data channels.. One of the 34-meter antennas at the Deep Space Networks Goldstone complex, DSS-24, was pointed at Saturn and listening for the signal that was expected to be here in just a few minutes. The data would be arriving at my computer as quickly as they could be sent back to Earth, though there was an agonizing hour-and-18-minute delay because of the distance the data had to travel. (We call this flyby T70, but it is actually Cassinis 71st flyby of Titan.). It was a nervous time for me - the previous night ...
After a 20-year voyage, NASAs Cassini spacecraft is poised to dive into Saturn this week to become forever one with the exquisite planet.
ORLANDO, Fla. -- Cliff Friedmans name may go far in Dallas real estate circles, but that doesnt come close to the 3 billion-mile trip it will begin in a few weeks. Friedmans name is one of about 435,000 names placed on a compact disc that will be in the New Horizons spacecraft when it launches from Cape Canaveral this week on a mission to Pluto and the outer edges of the solar system. My wife thinks it should be put out a little bit further, said Friedman, 48, a Dallas real estate attorney. The inclusion of names in the spacecraft is part of a public relations campaign to generate interest in the launch to the last unexplored planet in the solar system. When it reaches Pluto as early as 2015, the spacecraft will study the ninth planet, its large moon, Charon, as well as two other moons only discovered last year. The $700 million mission also should provide scientists with a better understanding of the Kuiper Belt, a mysterious disc-shaped region that lies beyond Neptune at the outer limits ...
NASAs Juno spacecraft has successfully completed its eighth science flyby of Jupiter, passing over the gas giants swirling cloud tops once again as it continues to unravel the mysteries of the largest planet in the Solar System. The mission itself also now has a new project manager, who will oversee the continuing flow of information being sent back, which has already greatly expanded our knowledge of Jupiter, upending some theories and presenting new questions.. All the science collected during the flyby was carried in Junos memory until yesterday, when Jupiter came out of solar conjunction, said the new Juno project manager, Ed Hirst, from NASAs Jet Propulsion Laboratory in Pasadena, California. All science instruments and the spacecrafts JunoCam were operating, and the new data are now being transmitted to Earth and being delivered into the hands of our science team.. The flyby actually occurred on Oct. 24, (Perijove 9) but the confirmation of its success was delayed until Oct. 31 by ...
The dramatic appearance of Saturn stems mainly from the spectacular rings. The atmosphere looks much less dramatic. The clouds of Saturn are much less colorful than those of Jupiter. This is because the composition of Saturns atmosphere includes more sulfur. This adds to Saturns overall yellow appearance. When you look closely, however, Saturns atmosphere is just as fierce as that of Jupiter! The atmosphere of Saturn, like Jupiter, is only a narrow region, compared to the vast interior of Saturn. The three clouddecks of Saturn are to be found mostly low in the atmosphere, while hazes of smog can be found higher up. Saturn is not much changed from its early evolution out of the primitive solar nebula, and in fact, may still be forming! Motions in the cloud patterns indicate that, like Jupiter, the basic weather of Saturn can be described as a striped pattern of winds. ...

The next day was an accomplishment in its own kind when the hatches between Dragon and the $100 billion orbiting lab were opened.. Now, the astronauts aboard the International Space Station would be unloading cargo from the first private spacecraft ever to visit the orbiting lab.. There are over 1,014 pounds (460 kilograms) of cargo on the Dragon spacecraft and the unpacking would only begin on May 28. According to NASA flight director Holly Ridings, Monday and Tuesday are very big cargo days on the space station with regard to Dragon. At least one of the crewmembers will be doing cargo operations almost all of their work days those days.. There are currently six astronauts living aboard the station. They include NASA astronauts Don Pettit and Joe Acaba, European astronaut Andre Kuipers, and Russian cosmonauts Oleg Kononenko, Gennady Padalka and Sergei Revin. The unloading would be handled by Acaba and Kuipers which would take a total of about 25 hours.. ...

On September 15, 2017, the Cassini mission will end. How do we know its going to happen on this exact date? Because NASA is going to crash the spacecraft into Saturn, killing it dead.. That seems a little harsh, doesnt it, especially for a spacecraft which has delivered so many amazing images to us over nearly two decades of space exploration? And as weve seen from NASAs Opportunity rover, still going, 13 years longer than anticipated. Or the Voyagers, out in the depths of the void, helping us explore the boundary between the Solar System and interstellar space. These things are built to last.. The problem is that the Saturnian system contains some of the best environments for life in the Solar System. Saturns moon Enceladus, for example, has geysers of water blasting out into space.. Cassini spacecraft is covered in Earth-based bacteria and other microscopic organisms that hitched a ride to Saturn, and would be glad to take a nice hot Enceladian bath. All they need is liquid water and a ...
Off all the space telescopes and craft currently in our Solar System, arguably the most amazing images of all have come via Cassini. The Nasa, European and Italian Space Agency spacecraft is currently...
Contrary to recent reports, NASAs Cassini spacecraft is not experiencing unexplained deviations in its orbit around Saturn, according to mission managers and orbit determination experts at
The discovery of carbocations and carbanions by Ion Neutral Mass Spectrometer (INMS) and the Cassini Plasma Spectrometer (CAPS) instruments onboard the Cassini spacecraft in Titan׳s upper atmosphere is truly amazing for astrochemists and astrobiologists. In this paper we identify the reaction mechanisms for the growth of the complex macromolecules observed by the CAPS Ion Beam Spectrometer (IBS) and Electron Spectrometer (ELS). This identification is based on a recently published paper (Ali et al., 2013. Planet. Space Sci. 87, 96) which emphasizes the role of Olah׳s nonclassical carbonium ion chemistry in the synthesis of the organic molecules observed in Titan׳s thermosphere and ionosphere by INMS. The main conclusion of that work was the demonstration of the presence of the cyclopropenyl cation - the simplest Huckel׳s aromatic molecule - and its cyclic methyl derivatives in Titan׳s atmosphere at high altitudes. In this study, we present the transition from simple aromatic molecules to the complex
NASA announced in June 2012 that the probe was detecting changes in the environment that were suspected to correlate with arrival at the heliopause.[58] Voyager 1 had reported a marked increase in its detection of charged particles from interstellar space, which are normally deflected by the solar winds within the heliosphere from the Sun. The craft thus began to enter the interstellar medium at the edge of the Solar System.[59] Voyager 1 became the first spacecraft to cross the heliopause in August 2012, then at a distance of 121 AU from the Sun, although this was not confirmed for another year.[60][61][62][63][64] As of September 2012, sunlight took 16.89 hours to get to Voyager 1 which was at a distance of 121 AU. The apparent magnitude of the Sun from the spacecraft was −16.3 (less than 30 times the brightness of the full moon).[65] The spacecraft was traveling at 17.043 km/s (10.590 mi/s) relative to the Sun. It would need about 17,565 years at this speed to travel a light-year.[65] To ...
Astronomers say it is likely that Saturns moon Enceladus hides a large body of liquid water just beneath its icy surface, BBC News reported.. More data returned from the Cassini probe, which periodically sweeps past the little moon, has provided even more evidence backing the idea of a sub-surface sea below the moons surface.. Experts theorize that it is the detection of negatively charged water molecules in the atmosphere of Enceladus. Such ions on Earth are often seen where liquid water is in motion, like waterfalls or crashing ocean waves.. Enceladus may not have any rollers but it does have a very active region near its south pole where water vapor and ice particles shoot through cracks in the surface and rise high into the moons atmosphere.. Andrew Coates from University College Londons Mullard Space Science Laboratory said they have seen water molecules that have additional electrons added.. Coates told BBC News there are only two ways they could be added -- from the ambient plasma ...
Cassini completed its initial four-year mission to explore the Saturn System in June 2008 and the first extended mission, called the Cassini Equinox Mission, in September 2010. Now, the healthy spacecraft is seeking to make exciting new discoveries in a second extended mission called the Cassini Solstice Mission.. The missions extension, which goes through September 2017, is named for the Saturnian summer solstice occurring in May 2017. The northern summer solstice marks the beginning of summer in the northern hemisphere and winter in the southern hemisphere. Since Cassini arrived at Saturn just after the planets northern winter solstice, the extension will allow for the first study of a complete seasonal period.. Cassini launched in October 1997 with the European Space Agencys Huygens probe. The probe was equipped with six instruments to study Titan, Saturns largest moon. It landed on Titans surface on Jan. 14, 2005, and returned spectacular results.. Meanwhile, Cassinis 12 instruments ...
similar, temperature-driven winds arise as sublimation of frost covering sun-facing slopes and dark sandy surfaces deep within the polar region creates intense slope winds away from the higher-standing layered deposits and permanent cap. The roughly circular, polar orbit of the Mars Global Surveyor (MGS) spacecraft affords a view not unlike that seen by low Earth-orbiting environmental satellites. Mars is roughly 6800 km (4226 mi) in diameter, and a 370 km (230 mi) average altitude gives a diameter to altitude ratio for MGS of 18.4:1. For comparison, the SeaStar spacecraft in Earth orbit follows a very similar orbit: its the diameter to altitude ratio is 17.5:1 (12,760 km or 7,928 mi diameter relative to a 705 km or 438 mi altitude). Each spacecraft covers the entire planet in 12 orbits.. In this figure, we compare a recent dust storm on Mars with one that occurred earlier this year on Earth. The top image shows a martian north polar dust storm observed on 29 August 2000. This image is part of ...
By Irene Klotz | CAPE CANAVERAL, Fla. CAPE CANAVERAL, Fla. Jupiters atmosphere features colossal cyclones and rivers of ammonia welling up from deep inside the solar systems largest planet, researchers said on Thursday, publishing the first insights from a NASA spacecraft flying around the gas giant.The cyclones were discovered as the Juno spacecraft made the first of at least 12 planned close encounters with Jupiter, which scientists believe set the stage for the development of Earth and other planets in the solar system.Juno found cyclones as big as 870 miles (1,400 km) in diameter swirling over Jupiters north and south poles, the research published in this weeks issue of the journal Science shows.
Metallic aluminum alloy foils exposed oil the forward, comet-facing surface of the aerogel tray oil the Stardust spacecraft are likely to have been impacted by the same cometary particle Population as the dedicated impact sensors and the aerogel collector. The ability of soft aluminum alloy to record hypervelocity impacts as bowl-shaped craters offers all opportunistic substrate for recognition of impacts by particles of a potentially wide size range. In contrast to impact surveys conducted oil samples from low Earth orbit, the simple encounter geometry for Stardust and Wild-2, with a known and constant spacecraft-particle relative velocity and effective surface-perpendicular impact trajectories, permits closely comparable simulation in laboratory experiments. For a detailed calibration program, we have selected a suite of spherical glass projectiles of uniform density and hardness characteristics, with well-documented particle size range from 10 mu m to nearly 100 mu m. Light gas gun buckshot ...
