Cosmic dust contains some complex organic compounds (amorphous organic solids with a mixed aromatic - aliphatic structure) that could be created naturally, and rapidly, by stars . (wikipedia.org)
[14] For example, cosmic dust can drive the mass loss when a star is nearing the end of its life , play a part in the early stages of star formation , and form planets . (wikipedia.org)
Zodiacal light caused by cosmic dust. (wikipedia.org)
Cosmic dust of the Andromeda Galaxy as revealed in infrared light by the Spitzer Space Telescope . (wikipedia.org)
Cosmic dust can also be detected directly ('in-situ') using a variety of collection methods and from a variety of collection locations. (wikipedia.org)

SwRI also will provide a scientific instrument and other technology for the Interstellar Mapping and Acceleration Probe (IMAP) spacecraft, scheduled to launch in 2024. (swri.org)
The launch timeframe, however, may be reviewed because the two spacecraft are being built with the same technologies as Russia's failed mission to Phobos, which proved vulnerable to cosmic radiation. (globalsecurity.org)
The next leg of the IBEX satellite's journey will take place in late September when the combined Pegasus air-launch system and the attached spacecraft will be ferried by Orbital's L-1011 carrier aircraft to Kwajalein Island, a part of the Marshall Islands in the mid-Pacific Ocean, roughly equidistant between Hawaii, Japan and Australia. (northropgrumman.com)
Advanced turbomachinery components play a critical role in launch vehicle and spacecraft liquid rocket propulsion systems. (sbir.gov)

There have been many published papers over the years showing specific instances where in the harsh environment some interesting biomass products emerge that can do quite well even in desert conditions," Jeffrey Manber, the CEO of Nanoracks, told E&T . "These plants evolve in space either through changes on the genetic level or through the effects of radiation, the absence of gravity, or a combination of all these factors. (theiet.org)
At the time, little was known as to the effects of cosmic radiation on organic matter. (rmg.co.uk)
Although radiation can have negative effects both on biological and mechanical systems, it can also be carefully used to learn more about each of those systems. (radiationtestsolutions.com)
Such tools could be of great utility in mission planning and epidemiological studies of the effects of space radiation on human health. (cdc.gov)
These cosmic ray propagation calculations provide the basis for a new atmospheric ionising radiation (AIR) model for air-crew dosimetry, calculation of effects on microelectronics, production of cosmogenic radionuclides and other uses. (bvsalud.org)

since the intensity of GCR, the most aggressive type of radiation, decreases within 6-12 months after peak solar activity. (persiadigest.com)

Eight whip antennas and four stub antenna arrays at opposite ends of the spacecraft structure were used for ground commands and telemetry. (nasa.gov)

The problem is that we need to figure out what needs to be improved," said Dr. Jim Adams of the Naval Research Laboratory in Washington. (nasa.gov)

On Earth, in comparison, these mutations occur at a rate of one in 200,000, according to Guo Rui, director of the Shaanxi Province Engineering Research Centre for Plant Space Breeding, who was quoted by the South China Post in 2018. (theiet.org)

The collection of articles provides more than 550 dose measurements for spacecraft and extra-vehicular activity in 42 combinations of inclination and altitude in low Earth orbit. (cdc.gov)

These risks mean spacecraft must have protective shielding. (osti.gov)

Low-energy radiation can be stopped by a spacecraft wall, but at higher energies the wall helps produce showers of secondary radiation, like splinters from a wall hit by a bullet. (nasa.gov)

As a consequence of this, the spacecraft did not perform an orbit-raising maneuver that had been scheduled to occur shortly after orbital insertion. (wikipedia.org)

All of these kinds of space radiation represent ionizing radiation. (radiationtestsolutions.com)
Less energetic, non-ionizing radiation does not have enough energy to remove electrons from the material it crosses. (radiationtestsolutions.com)
While many forms of non-ionizing and ionizing radiation have become essential to our everyday life, each kind of radiation can cause damage to living and non-living objects, and precautions are required to prevent unnecessary risks. (radiationtestsolutions.com)
