OSIRIS-REX’s visit to the asteroid Bennu revealed that this little world is more rubble pile than solid rock.
Rubble piles in space aren't like the solid ones that gravity holds on the ground. New analysis shows that NASA's OSIRIS-REX probe punched right through the surface of rubble-pile asteroid 101955 Bennu while on its way to collect a sample.
The Unexpected Way We Might Prevent An Asteroid From Hitting Earth
While the chances of something similar happening to Earth again anytime soon are relatively low, NASA scientists, among others, are reassuringly keeping an eye on things for us regardless.
According to planetary scientist Detlef Koschny, we have mapped 90% of asteroids that are 1 kilometer in size or larger, with scientists confident that none of these poses a threat to Earth anytime in the next 100 years (via Earthsky.org ).
NASA commissions review of delayed asteroid mission Psyche | Space
NASA commissioned an independent review Thursday (July 14) to look in detail at the issues delaying its Psyche mission well into 2023.
The Psyche spacecraft , which had been targeting launch this fall to the metal-rich asteroid of the same name, ran into a set of software issues so complex that in June , the spacecraft's launch was pushed to at least July 2023 amid overall uncertainty about the mission's future.
NASA May Cancel Mission to Zillion Dollar Asteroid
But now, it looks like those efforts are in trouble — a NASA update has revealed that the mission is under review and may ultimately be scrapped.
NASA stipulates that the assessment intends to examine the "project and institutional issues" that have led to the uncrewed spacecraft's allegedly software-related delays .
Always look up: Earth's top seven asteroid defences
If an asteroid threat emerged, Earth would need to be ready. Scientists are continually working to give the planet the best range of defensive strategies.
One day we might scan the skies and see it coming: an asteroid heading straight for Earth. Our response would depend on how far away the asteroid was when we saw it, how big it was and where exactly it was going to land.
Galaxy Mapper Tracks Asteroids Closer to Home - Eos
The primary objective of the European Space Agency's (ESA) Gaia satellite is to observe more than a billion stars to create the most accurate and complete map of the Milky Way.
Gaia's new release also contains precise positions and velocities of more than 150,000 asteroids in our solar system, a significant fraction of the 1.2 million asteroids we know of today .
'Hopping' space dust may help asteroids bust a move | Space
Snap, crackle, pop! Dust 'hopping' on asteroids might influence how these small bodies migrate through space.
Fresh imagery from asteroids Bennu and Ryugu helped inform the new findings, which might explain the pathways these space rocks take as they orbit the sun and occasionally, stray near Earth .
NASA asteroid mission's Lindy Elkins-Tanton writes memoir - CSMonitor.com
When Lindy Elkins-Tanton applied to the Massachusetts Institute of Technology, the high school math teacher who wrote her recommendation told her, "You'll never get in.
It was interesting for me to see those experiences add up as I was writing the book. In some places those words really stuck with me, like with my math teacher: "I must not be good at math." It's something I rail against – why is it OK to say girls aren't good at math?
