JAXA’s Asteroid Explorer “Hayabusa2” collected a sample from asteroid Ryugu on 22 February 2019. The touchdown was captured using the onboard small monitor camera (CAM-H). The image of the site immediately after touchdown was taken with the Optical Navigation Camera – Wide angle (ONC-W1) on 22 February 2019.

Ryugu is probably a chip off one of these two other asteroids. Japan’s Hayabusa2 team has narrowed down the asteroid’s origins based on its color. By Lisa Grossman, 3:20pm, March 20, 2019.

NASA’s OSIRIS-REx mission returned the first scientific observations, revealing that asteroid Bennu is an active asteroid. OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer) is the first U.S. mission to sample an asteroid (near-Earth asteroid Bennu), retrieve surface material and return it to Earth for study in September 2023. Dante Lauretta, OSIRIS-REx principal investigator, explained the findings in a media teleconference.

Surprising astronomers, Bennu spits plumes of dust into space. It’s the first time astronomers have seen such activity on an asteroid. By Lisa Grossman, 2:55pm, March 19, 2019.
