NASA’s OSIRIS-REx spacecraft finds particles flying off asteroid Bennu
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.
Japanese probe lands on asteroid to capture sample
Japan’s Hayabusa 2 spacecraft briefly landed on an asteroid Thursday more than 200 million miles from Earth and fired a bullet to scoop up a rocky sample, successfully accomplishing one of the mission’s most challenging maneuvers before returning the asteroid specimen to scientists on the ground in December 2020.
ULA wins contract to launch NASA’s Lucy mission to visit unexplored asteroids
NASA has selected United Launch Alliance’s Atlas 5 rocket to dispatch the Lucy spacecraft on a mission from Cape Canaveral in October 2021 to fly by seven unexplored asteroids, including six objects locked in orbits leading and trailing Jupiter, where scientists expect swarms of miniature worlds could hold clues about the formation of the solar system.
OSIRIS-REx finds rugged terrain on asteroid Bennu
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.
