Japan capsule carrying asteroid samples retrieved in Australia
TOKYO — Japan’s space agency said its helicopter search team retrieved a capsule carrying asteroid samples Sunday after it successfully landed in a remote area in southern Australia as planned.
The spacecraft Hayabusa2 released the small capsule Saturday and sent it toward Earth to deliver samples from a distant asteroid that could provide clues to the origin of the solar system and life on our planet, the Japan Aerospace Exploration Agency (JAXA) said.
“The capsule collection work at the landing site was completed,” the agency tweeted about four hours after the capsule landed. ”We practiced a lot for today ... it ended safe.”
The return of the capsule with the world’s first asteroid subsurface samples comes weeks after NASA’s OSIRIS-REx spacecraft made a successful touch and grab of surface samples from asteroid Bennu. China, meanwhile, announced this week its lunar lander collected underground samples and sealed them within the spacecraft for return to Earth, as space developing nations compete in their missions.
Early Sunday, the capsule briefly turned into a fireball as it reentered the atmosphere 75 miles above Earth. At about 6 miles above ground, a parachute opened to slow its fall and beacon signals were transmitted to indicate its location.
“It was great. ... It was a beautiful fireball, and I was so impressed,” said JAXA’s Hayabusa2 project manager, Yuichi Tsuda, as he celebrated the successful capsule return and safe landing from a command center in Sagamihara, near Tokyo. “I’ve waited for this day for six years.”
Beacon signals were detected, suggesting the parachute successfully opened and the capsule landed safely in a remote, sparsely populated area of Woomera, Australia, said JAXA official AkitakaKishi.
About two hours after the capsule’s re-entry, JAXA said its helicopter search team found the capsule in the planned landing area. The retrieval of the pan-shaped capsule, about 15 inches in diameter, was completed about twohours later.
The fireball could be seen even from the International Space Station. Japanese astronaut Soichi Noguchi, who is now on a six-month mission there, tweeted: “Just spotted #hayabusa2 from #ISS! Unfortunately not bright enough for handheld camera, but enjoyed watching capsule!”
Hayabusa2 left the asteroid Ryugu, about 180 million miles away, a year ago. After it released the capsule, it moved away from Earth to capture images of the capsule descending toward the planet as it set off on a new expedition to another distant asteroid.
The capsule descended from 136,700 miles away after it was separated from Hayabusa2 in a challenging operation that required precision control. JAXA officials said they hoped to conduct a preliminary safety inspection at an Australian lab and bring the capsule back to Japan early next week.
Dozens of JAXA staff have been working in Woomera to prepare for the sample return. They set up satellite dishes in the target area inside the Australian Air Force test field to receive the signals.
Australian National University space rock expert Trevor Ireland, who was in Woomera for the arrival of the capsule, said he expected the Ryugu samples to be similar to the meteorite that fell in Australia near Murchison in Victoria state more than 50 yearsago.
