To both understand specific asteroids in case we need to deflect them, and to more broadly understand the asteroid population, we need to characterize the asteroids: collect many telescopic, and occasionally spacecraft observations, that can tell us things like spin rate, composition, physical properties, and even whether what at first appears to be one asteroid is actually two: a binary pair. (planetary.org)
Techniques include the slow gravity tractor (spacecraft gravity pulls the asteroid), to the mid-range kinetic impactor (slam one or more spacecraft into the asteroid), to developing techniques such as laser ablation (vaporizing rock to create jets that push the asteroid), to last resort shorter warning nuclear options (nuclear disruption, or stand-off nuclear ablation: rapid vaporizing of rock on one part of the asteroid).

That's something relegated to the movies - it makes a good movie, but we do not see in our studies any technique that would require the involvement of astronauts," Johnson said, adding that NASA's proposed asteroid-deflection techniques "would all be done by robotic spacecraft. (livescience.com)
This involves developing new technologies for "rapid-response NEO [near-Earth object] reconnaissance missions," in which a spacecraft could launch toward an Earth-bound asteroid and somehow change the space rock's course so that it no longer posed a threat. (livescience.com)

As the impactor is getting ready to impact the asteroid, the observer spacecraft pulls back and images what is going on so you can confirm the impact was solid, -not a glancing blow - and then after impact is done, the observer spacecraft goes back in and makes another precision orbit determination so that you can confirm that you changed its velocity so that it no longer will hit the Earth.

After a journey of almost four years and 2 billion miles, a Japanese space probe is closing in on its target , a small asteroid named Ryugu, the Japan Aerospace Exploration Agency (JAXA) said on Sunday. (nbcnews.com)
The unmanned craft, Hayabusa 2, is scheduled to rendezvous with Ryugu on Wednesday . (nbcnews.com)
In recent days, Hayabusa 2 has beamed back a series of dramatic photos of Ryugu, which circles the sun from a distance ranging from just within Earth's orbit to just outside Mars' orbit . (nbcnews.com)
Asteroid Ryugu as photographed by Hayabusa 2 on June 24, 2018. (nbcnews.com)
Carbon-containing asteroids like Ryugu have attracted interest in part because they're thought to harbor water-bearing minerals that may hold clues about the origin and evolution of our solar system. (nbcnews.com)
What's more, Chodas said, "it is possible that we may someday extract water or oxygen from asteroids like Ryugu, which means they could be used as refueling stops for missions on the way to Mars. (nbcnews.com)

The target is the asteroid Ryugu. (earthsky.org)
The coolest mission you haven't heard of just hit a major milestone: the Japanese Hayabusa 2 probe has reached its destination, the asteroid Ryugu, and just deployed a pair of landers to its surface. (inventiva.co.in)
That destination is an asteroid in an orbit between the Earth and Mars named Ryugu. (inventiva.co.in)
The big news will come next year, when Hayabusa 2 itself drops down to the surface with the "small carry-on impactor," which it will use to create a crater and sample below the surface of Ryugu. (inventiva.co.in)
Ground teams have approved plans for Japan's Hayabusa 2 sample return mission to briefly land on asteroid Ryugu for the second time on 11 July, aiming for a targeted touch-and-go to gather material exposed by an explosive impactor released by the robot explorer in April. (astronomynow.com)
In the samples collected from the asteroid Ryugu, magnetite displays natural remanent magnetization due to nebular magnetic field, whereas contemporaneously grown iron sulfide does not display stable remanent magnetization. (nature.com)
These results show that both magnetite and sulfide could have formed simultaneously during the aqueous alteration in the parent body of the asteroid Ryugu. (nature.com)
In contrast, samples collected from the near-Earth C-type asteroid (162173) Ryugu by the Hayabusa2 expedition and brought back to the Earth in December 2020 have a clear history, and have only been exposed to the Earth's magnetic field and atmosphere for a short time. (nature.com)

The plan is that Hayabusa 2 will survey the asteroid for 18 months, depart in December, 2019, and return to Earth with an asteroid sample in December, 2020. (earthsky.org)
These proximity operations will include imaging and mapping the asteroid and a close-up rendezvous maneuver like the one used to obtain material from Bennu in October 2020 . (space.com)

The further ahead of an impact we find a threatening asteroid, the more options exist to change its orbit so it won't hit the Earth. (planetary.org)
We need to track it - get lots of telescopic observations over days, months, and years, each of which helps us refine the predicted orbit of the asteroid. (planetary.org)
Without sufficient observations, sometimes needed quickly after discovery, asteroids can even be lost: the orbit is so uncertain we don't know where and when to find them again. (planetary.org)
Although the asteroid is expected to return to Earth's orbit in 2026, scientists have determined that it poses no threat to our planet during that time. (indiatimes.com)

The more the asteroid is observed, and the greater the period of time over which it is observed, the more precisely its orbit can be calculated. (everything2.com)
When this data was taken into account, the possibility of an impact in 2029 disappeared entirely (though the asteroid will still pass within the moon's orbit) and the cumulative probability of any impact at all anytime in the 21st century was lowered to .0018%, or approximately 1 in 56,000. (everything2.com)
In an article on Universe Today published yesterday, Schweickart said the technology is available today to send a mission to an asteroid in an attempt to move it, or change its orbit so that an asteroid that threatens to hit Earth will pass by harmlessly. (universetoday.com)
In a phone interview, Schweickart described two types of "deflection campaigns" for a threatening asteroid: a kinetic impact would roughly "push" the asteroid into a different orbit, and a gravity tractor would "tug slowly" on the asteroid to precisely "trim" the resultant change course by using nothing more than the gravitational attraction between the two bodies.

Asteroids are highly variable, including in ways that could affect missions to deflect or disrupt an Earth-threatening asteroid. (planetary.org)
