    Results from Mobile Asteroid Surface Scout (MASCOT)'s landing on Ryugu indicate it is a "a fragile cosmic 'rubble pile'"

    http://www.spacedaily.com/reports/Th..._pile_999.html

    In the summer of 2018, the asteroid Ryugu, which measures only approximately 850 metres across, was visited by the Japanese Hayabusa2 spacecraft. On board was the 10-kilogram German-French Mobile Asteroid Surface Scout (MASCOT) - a lander no bigger than a microwave oven and equipped with four instruments. On 3 October 2018 MASCOT, operated by the control centre at the German Aerospace Center (Deutsches Zentrum fur Luft- und Raumfahrt; DLR) in Cologne, separated from its mother craft 41 metres above the asteroid.

    It touched down on the surface for the first time six minutes after deployment, before coming to a halt 11 minutes later, like a dice on a board game moving in slow motion. Over the course of 17 hours, MASCOT carried out experiments in various places amid the large boulders.

    Evaluation of the image data from DLR's MASCOT camera (MASCam) showing the descent and Ryugu's surface has now revealed a detailed view of a fragile 'rubble pile' made up of two different, almost black, types of rock with little internal cohesion. The scientific team, led by planetary researcher Ralf Jaumann from the DLR Institute of Planetary Research in Berlin-Adlershof, have now reported on this in the current issue of Science.

    "Hayabusa2 Lander Mania: Results from MASCOT, Plans for MINERVA-II2"

    http://www.planetary.org/blogs/jason...der-mania.html

    Japan's Hayabusa2 spacecraft only has about 3 months left at asteroid Ryugu, and between now and its departure it’s going to drop more stuff on the surface. Although operations are still ongoing, mission scientists have been busy: there’s a new paper out in Science analyzing what the MASCOT lander saw as it tumbled around the asteroid's rocks and boulders for 17 hours last October.

    "Japan’s Next Asteroid Robot – Ready for Deployment"

    https://www.leonarddavid.com/japans-...or-deployment/

    Japan’s Hayabusa2 asteroid explorer is soon to dispatch a new robot onto space rock of ages, Ryugu.

    The spacecraft is slated to unload the roughly 2.2 pounds (one kilogram) Minerva-II2 next month – a device equipped with a camera, thermometer, photodiode, and accelerometer.

    Minerva is short for MIcro-Nano Experimental Robot Vehicle for Asteroid.
