NASA’s OSIRIS-REx mission was designed to collect 60 grams from asteroid Bennu, but the moment the probe touched down, the surface gave way and the arm sank nearly half a meter. The blast of nitrogen ...

The Trump administration wants to cancel funding for several NASA science missions with ties to the University of Arizona, ...

Scientists gear up to explain significance of event while preventing public panic over unfounded fears of an asteroid strike ...

The asteroid, named Apophis, will pass around 20,000 miles from Earth's surface on April 13, 2029—closer than many satellites ...

Space is big. Disturbingly big. And most of the time, it goes about its business without us paying much attention. But every so often, something out there catches scientists’ eyes in a way that stops ...

In April 2029, asteroid Apophis will pass Earth at a distance that sounds almost unreal on paper. About 20,000 miles away from the surface, close enou.

Scientists studying Bennu samples have discovered that its chemistry is far from uniform. Organic compounds and minerals cluster into three distinct types of regions, each shaped differently by past ...

In one of the biggest surprises of NASA’s OSIRIS-REx mission, its target asteroid, Bennu, turned out to be a jagged, rugged world covered in large boulders, with few of the smooth patches that earlier ...

Asteroid Bennu appeared different than expected because its surface is dominated by large boulders instead of smooth regions previously predicted by Earth-based observations. When NASA’s OSIRIS REx ...

The surface of asteroid Bennu has long left questions for scientists after a NASA planetary science mission showed the asteroid was actually more rough and jagged than previously expected. NASA's ...

When scaled up to boulder size, the thermal inertia results fell into agreement with what the spacecraft had measured at the asteroid. Where scientists once expected the boulders of Bennu to be ...
