Rover 1A Hops on Asteroid Ryugu
Image Credit & Copyright: ISAS [3] , JAXA [4] , Hayabusa2 Mission [5]

Explanation: Two small robots have begun hopping around the surface of
asteroid Ryugu. The rovers, each the size of a small frying pan [6] , move
around the low gravity of kilometer-sized 162173 Ryugu [7] by hopping,
staying aloft for about 15 minutes and typically landing again several meters
away. On Saturday, Rover 1A returned an early picture [8] of its new home
world [9] , on the left, during one of its first hops. On Friday, lander
MINERVA-II-1 [10] detached from its mothership Hayabusa2 [11] , dropped
Rovers 1A and 1B, and then landed [12] on Ryugu. Studying Ryugu [13] could
tell humanity [14] not only about Ryugu's surface and interior, but about what
materials were available in the early Solar System [15] for the development
of life [16] . Two more hopping rovers are planned [17] for release, and
Hayabusa2<a/> itself is scheduled to collect a surface sample from Ryugu [19]
and return it to Earth [20] for detailed analysis before 2021.
