Hayabusa2 gets underground sample from asteroid
A Japanese spacecraft landed on a distant asteroid on July 11 and collected underground samples that scientists hope will provide clues to the origin of the solar system billions of years ago, Japan's space agency said.
The Hayabusa2 spacecraft had created a landing crater on the rocky asteroid in April by dropping a copper impactor. It landed near that crater on July 11 and collected samples that scientists believe contain valuable data unaffected by space radiation and other environmental factors.
Hayabusa2 is the first spacecraft to successfully collect underground samples from an asteroid.
The Japan Aerospace Exploration Agency, or JAXA, said data shows Hayabusa2 touched down and rose safely after collecting the samples.
"We took a historic step," said Tsuda Yuichi, the Hayabusa2 project manager. "On a scale of 1 to 100, we scored 1,000."
The asteroid, named Ryugu, was about 300 million kilometers from Earth at the time. Hayabusa2 is expected to leave the asteroid later this year and return home at the end of 2020.
Hayabusa2 made a similar landing at another location on the asteroid in February and collected topsoil samples. (AP)
