JAXA's asteroid landers share photos from Ryugu's surface by Brooks Hays Washington (UPI) Sep 27, 2018 JAXA released new photos of the asteroid Ryugu's rugged landscape. The images were captured by the mission's two MINERVA-II1 rovers, named Rover 1A and Rover 1B. The miniature, roly-poly-shaped landers were released last week by the Japanese space agency's asteroid-circling probe, Hayabusa-2. The landers successfully touched down on the asteroid's surface on Sunday. JAXA posted video and photos captured by the landers' cameras on Twitter, revealing Ryugu's craggy surface up-close. Hayabusa-2 rendezvoused with asteroid Ryugu earlier this summer after a 3.5-year journey. In the coming weeks, the two landers will use their cameras and instruments, including temperature and optical sensors, to observe Ryugu. Scientists believe Ryugu was formed not long after the birth of the solar system and could offer scientists insights into how the solar system formed and evolved. Last month, NASA's own asteroid-targeting probe, OSIRIS-REx, began its approach toward the asteroid Bennu.
Four extremely young asteroid families identified Sao Paulo, Brazil (SPX) Sep 26, 2018 Four families of extremely young asteroids have been identified by researchers affiliated with Sao Paulo State University (UNESP) in Guaratingueta, Brazil. An article on the discovery has been published in Monthly Notices of the Royal Astronomical Society. "We identified the new families by means of numerical simulation using the backward integration method (BIM), which is much more precise than other methods for dating asteroid families. But BIM only works for really young families that are less ... read more
