The proposed national US budget for 2026 contains a few nasty surprises for NASA, and some serious disappointments—among them ...

Bennu is classified as a “potentially hazardous asteroid,” meaning the object is more than 460 feet (140 meters) wide and could theoretically come within 4.65 million miles of Earth.

The asteroid appeared as a speck of light to the spacecraft’s UA-built PolyCam camera, but Bennu will seem to grow now that OSIRIS-REx has begun the approach phase of the mission.

On Sunday, Sept. 24, 2023, the spacecraft will fly by Earth and drop off what is expected to be at least a cupful of rubble it grabbed from the asteroid Bennu, closing out a seven-year quest.

In 2018, it arrived at Bennu, a near-Earth asteroid as wide as the Sears Tower is tall. The mission collected pieces of the asteroid and brought them back to Earth in 2023.

A series of images from NASA’s OSIRIS-REx mission show the spacecraft approach and touch down on asteroid Bennu’s surface, over 200 million miles away from Earth, to collect a sample on ...

Asteroid 2024 YR4 captured a lot of headlines shortly after its discovery because it had a slim chance of hitting Earth. The object is estimated to be between 130 and 300 feet wide, large enough ...

A potentially hazardous asteroid roughly the size of an aircraft carrier is due to pass within 2.8 million miles (3.5 million km) of Earth on June 5 and you can watch it happen live online.

What was the most surprising or unexpected thing that happened as the mission unfolded? There are so many. I call Bennu the “trickster asteroid” because it constantly surprised us and challenged us.
