Japan’s capsule with asteroid samples retrieved in Australia

  • Japan's spacecraft Hayabusa2 released the small capsule on Saturday and sent it toward Earth
  • The samples were taken from an asteroid that could provide clues to the origin of the solar system and life on planet Earth

TOKYO: Japan’s space agency said its helicopter search team on Sunday retrieved a capsule carrying asteroid samples after it successfully landed in a remote area in southern Australia as planned.
The spacecraft Hayabusa2 released the small capsule on 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 said.
“The capsule collection work at the landing site was completed,” the agency said in a tweet 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-go 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 120 kilometers (75 miles) above Earth. At about 10 kilometers (6 miles) above ground, a parachute was 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 Akitaka Kishi.
About two hours after the capsule’s reentry, JAXA said its helicopter search team found the capsule in the planned landing area. The retrieval of the pan-shaped capsule, about 40 centimeters (15 inches) in diameter, was completed about two hours later.
The fireball could be seen even from the International Space Station. A 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 300 million kilometers (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 220,000 kilometers (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 at several locations 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 years ago.
“The Murchison meteorite opened a window on the origin of organics on Earth because these rocks were found to contain simple amino acids as well as abundant water,” Ireland said. “We will examine whether Ryugu is a potential source of organic matter and water on Earth when the solar system was forming, and whether these still remain intact on the asteroid.”
Scientists say they believe the samples, especially ones taken from under the asteroid’s surface, contain valuable data unaffected by space radiation and other environmental factors. They are particularly interested in analyzing organic materials in the samples.
JAXA hopes to find clues to how the materials are distributed in the solar system and are related to life on Earth. Yoshikawa, the mission manager, said 0.1 gram of the dust would be enough to carry out all planned researches.
For Hayabusa2, it’s not the end of the mission it started in 2014. It is now heading to a small asteroid called 1998KY26 on a journey slated to take 10 years one way, for possible research including finding ways to prevent meteorites from hitting Earth.
So far, its mission has been fully successful. It touched down twice on Ryugu despite the asteroid’s extremely rocky surface, and successfully collected data and samples during the 1½ years it spent near Ryugu after arriving there in June 2018.
In its first touchdown in February 2019, it collected surface dust samples. In a more challenging mission in July that year, it collected underground samples from the asteroid for the first time in space history after landing in a crater that it created earlier by blasting the asteroid’s surface.
Asteroids, which orbit the sun but are much smaller than planets, are among the oldest objects in the solar system and therefore may help explain how Earth evolved.
Ryugu in Japanese means “Dragon Palace,” the name of a sea-bottom castle in a Japanese folk tale.

  • Taliban spokesman says first vice president wants to sabotage the peace talks

KABUL: Afghanistan’s First Vice President Amrullah Saleh on Monday demanded the execution of Taliban prisoners as violence surges in the country in spite of US-sponsored talks between the government and the militants.

Under mounting US pressure and following months of delay, Kabul released last summer thousands of Taliban prisoners from its custody as part of the landmark accord between the group and Washington.

But now there has been a spike in arrests of suspected Taliban fighters linked with recent attacks.

“These arrests should be executed so that it becomes a lesson for others,” Saleh told a routine security meeting in Kabul.

“The arrested like nightingales admit (to conducting attacks), but their all hope is that they will be freed one day without real punishment … any terrorist detainee should be executed.”

Known as the staunchest anti-Taliban leader in government and consistently opposed to talks with the Taliban, Saleh said he would raise his demand for the executions in the High Council of the Judiciary. His spokesman, Rezwan Murad, said the first vice president has also shared his demand with President Ashraf Ghani.

“Currently, around 1,000 Taliban prisoners have been sentenced to capital punishment,” Prison Administration spokesman in Kabul, Farhad Bayani, told Arab News.

“Such news is provoking, he wants to sabotage the process of talks,” said Zabihullah Mujahid, a Taliban spokesman, when reached by Arab News for reaction to Saleh’s push.

“We will severely take the revenge of any type of inhuman and cruel treatment of our prisoners.”

The Afghan government was excluded from the US and Taliban deal signed last February in Doha, which as per the agreement is also hosting the current peace talks between Kabul and the insurgents.

In spite of the ongoing talks, violence has surged in Afghanistan and both the government and the Taliban accuse each other for its escalation.

Hundreds of civilians have lost their lives in the violence, which has displaced tens of thousands of people since the February deal, while Kabul has endured a resurgence in assassination attacks and magnet bombs.

Prior to Saleh, some residents and lawmakers also demanded the executions of Taliban members suspected of being behind major attacks. Heather Barr, interim co-director for Human Rights Watch, told Arab News: “Human Rights Watch opposes the use of the death penalty under all circumstances. It is a uniquely cruel and irreversible punishment and we are glad to see that there has been some global progress towards abolition of the death penalty.”

She added: “Afghanistan has already seen so much violence and death and continues to experience this violence every day. There is an urgent need for accountability for the many human rights violations that have been inflicted during Afghanistan’s many years of war, but executions will not bring the justice Afghans so badly need.”
