NASA selects site for OSIRIS-REx to collect asteroid samples

December 12, 2019

Using precise autonomous navigation algorithms, NASA’s OSIRIS-REx spacecraft will descend to the surface of an asteroid next year, aiming to retrieve rock specimens for return to Earth from a gravelly pit flanked by hazardous boulders, scientists said Thursday.

NASA’s OSIRIS-REx spacecraft finds particles flying off asteroid Bennu

March 19, 2019

The early months of NASA’s OSIRIS-REx mission’s exploration of asteroid Bennu have revealed big surprises, scientists said Tuesday, including plumes of particles streaming away from the asteroid, sometimes with enough velocity for rocks to break out of Bennu’s tenuous gravitational grip and escape into space.

OSIRIS-REx finds rugged terrain on asteroid Bennu

January 31, 2019

Some time next year, NASA’s OSIRIS-REx spacecraft will descend to the boulder-strewn surface of asteroid Bennu, reach out with a robotic arm, and fetch a sample for return to Earth, but an initial survey of the space rock millions of miles from Earth suggests the robotic mission may have few suitable targets for the touch-and-go maneuver.

Two NASA probes catch first glimpses of primordial targets

August 29, 2018

Two NASA spacecraft — the OSIRIS-REx asteroid sample return mission and the New Horizons probe at the edge of the solar system — have captured their first looks at their targets as they approach a pair of primordial relics for the first time.

Asteroid Ryugu revealed by approaching Japanese spacecraft

June 20, 2018

In the final days of a three-and-a-half year pursuit, Japan’s Hayabusa 2 sample return spacecraft is beaming back clearer images of asteroid Ryugu, an unexplored object that scientists say resembles a spinning top or dumpling nearly 180 million miles from Earth.

Asteroid missions on track to reach their destinations in 2018

January 18, 2018

Pioneering spacecraft from NASA and the Japanese space agency promise to reveal two unexplored asteroids later this year, officials said Wednesday, beginning surveys that will culminate in daring descents to capture samples for return to Earth, where eager scientists await a hands-on look at the specimens.

Asteroid-bound probe returns Earth-moon family portrait

October 12, 2017

Ten days after a swingby to receive a gravitational boost toward its asteroid target, NASA’s OSIRIS-REx spacecraft turned one of its cameras back toward Earth, resolving its bluish home planet hanging in the void of space accompanied by the moon.

NASA’s OSIRIS-REx probe moonlights as asteroid sleuth

February 1, 2017

On course to collect specimens from asteroid Bennu after its launch last year, NASA’s OSIRIS-REx spacecraft will search this month for objects locked in orbits near Earth, a bonus science opportunity to locate possible fragments of the primordial building blocks that formed our home planet.
