A robotic probe the size of a shoebox set itself down on the asteroid Ryugu, more than 180 million miles from Earth, and conducted a 17-hour survey of its rocky surroundings.
The foot-wide, German-built lander is called MASCOT, which stands for Mobile Asteroid Surface Scout. It was ejected from Japan’s Hayabusa 2 probe from a height of 51 meters (167 feet) and drifted downward to Ryugu at walking speed.
“It could not have gone better,” Tra-Mi Ho, MASCOT project manager at the DLR Institute of Space Systems, said today in a status update. “From the lander’s telemetry, we were able to see that it separated from the mothercraft and made contact with the asteroid surface approximately 20 minutes later.”
