TOKYO (AP) — Japan’s space agency said Monday it has confirmed the presence of black soil samples inside a capsule that the spacecraft Hayabusa2 brought back from a distant asteroid last week.
The pan-shaped capsule, 40 centimeters (15 inches) in diameter, was dropped by Hayabusa2 from space onto a spot in a sparsely populated Australian desert on Dec. 6. It arrived in Japan last Tuesday for research that will hopefully provide insights into the origins of the solar system and life on Earth.
The Japan Aerospace Exploration Agency said its scientists opened the capsule and found an unspecified amount of sandy black particles.
“It’s obviously from Ryugu,(asterisk) the asteroid, JAXA said in a statement.
JAXA said it will continue an initial examination ahead of fuller studies of the samples later.
The samples were gathered from touchdowns that Hayabusa2 made last year on Ryugu, more than 300 million kilometers (190 million miles) from Earth. The landings were more difficult than expected because of the asteroid’s extremely rocky surface.
The first landing collected samples from Ryugu’s surface and the second from underground. Each was stored separately.
Scientists are hoping the asteroid’s subsurface samples can provide information from billions of years ago unaffected by space radiation and other environmental factors. JAXA scientists say they are particularly interested in organic materials in the samples to learn about how they were distributed in the solar system and if they are related to life on Earth.
Following studies in Japan for about a year, some of the samples will be shared with NASA and other international groups for additional research beginning in 2022.
