The first views of 4.5-billion-year-old asteroid Bennu samples collected in space and recently brought reveal water and high-carbon content.

After traveling billions of miles, the NASA OSIRIS-REx mission has landed a capsule with rocks and dust from the asteroid Bennu in the Utah desert.

Researchers aim to update Apollo-era information about rocket-powered landings on dusty celestial bodies like Mars with new supercomputer simulations.

"Trial and error" doesn't work for testing whether rocket engines can handle flight. A new machine learning method could make things simpler and safer.

Researchers have taken a first step toward the "rotating detonation engine," which could make rockets more fuel-efficient and lightweight.

After several months evaluating data from four candidate sites on the asteroid Bennu, scientists have finally identified the best sample collection spot.

"Among Bennu's many surprises, the particle ejections sparked our curiosity, and we've spent the last several months investigating this mystery."

The mission to get a bit of the asteroid Bennu's surface back to Earth in 2023 is facing some unexpected challenges. Here are four new findings.
