During the touchdown, Hayabusa2 is programmed to extend a pipe and shoot a pinball-like object into the asteroid to blow up material from beneath the surface. If that succeeds, the craft would then collect samples to eventually be sent back to Earth. Three such touchdowns are planned.
Japanese Education Minister Masahiko Shibayama said the space agency had concluded from its data after the first touchdown that the steps to collect samples were performed successfully. JAXA, as the Japanese space agency is known, has likened the touchdown attempts to trying to land on a baseball mound from the spacecraft's operating location of 20 kilometers (12 miles) above the asteroid.
The asteroid, named Ryugu after an undersea palace in a Japanese folktale, is about 900 meters (3,000 feet) in diameter and 280 million kilometers (170 million miles) from Earth.
