The InSight lander seems to have been hit by one of Mars' famous dust devils, but don't worry--the NASA probe is just fine. If anything, the sudden blast of wind helped to clear off some annoying dust that had been collecting on the probe's solar panels. The passing wind vortex also produced some cool science.
NASA, FEMA, and other national and international agencies are once again gearing up for a hypothetical asteroid impact preparedness scenario. They hope to learn the best strategies for responding to a potential strike, starting from the moment a threatening asteroid is first detected by astronomers.

For that to happen,...
NASA's Curiosity rover shook the science community six years ago when it apparently detected traces of methane--an important chemical linked to life--on Mars. Researchers failed to confirm these results in the years that followed, but that's now changed thanks to a re-analysis of data collected from orbit.
With its long, bright tail, this object bears an uncanny resemblance to a comet, but it's actually an active asteroid. New observations suggest the asteroid is spinning so quickly that it's starting to break down and crumble, in what is a relatively rare cosmological phenomenon.
