TOKYO (AP) — Japan’s space agency said its Hayabusa2 spacecraft will follow up last month’s touchdown on a distant asteroid with another risky mission — to drop an explosive to make a crater and collect underground samples to get possible clues to the origin of the solar system.
Hayabusa2 successfully touched down on the boulder-rich asteroid on February 22, when it also collected some surface fragments.
The Japan Aerospace Exploration Agency said yesterday that Hayabusa2 is to drop a copper impactor on the asteroid April 5 to collect samples from deeper underground. The mission requires an immediate evacuation of the spacecraft so it won’t get hit by flying shards from the blast.
The asteroid, named Ryugu after an undersea palace in a Japanese folktale, is about 300 million kilometres (180 million miles) from Earth.
