Indian-American among 18 astronauts selected for NASA's manned Moon mission


DEC 11, 2020 WASHINGTON: An Indian-American is among the 18 astronauts selected by NASA for its manned mission to the Moon and beyond. NASA on Wednesday named the 18 astronauts -- half of them women -- who will train for its Artemis moon-landing programme. Raja Jon Vurputoor Chari, 43, a graduate of the US Air Force Academy, MIT, and US Naval Test Pilot School, is the only Indian-American in the list. He was selected by NASA to join the 2017 Astronaut Candidate Class. He reported for duty in August 2017 and having completed the initial astronaut candidate training is now eligible for a mission assignment. "My fellow Americans, I give you the heroes of the future who will carry us back to the Moon and beyond: the Artemis Generation," Vice President Mike Pence said at NASA''s Kennedy Space Centre in Florida on Wednesday. "It really is amazing to think that the next man and the first woman on the Moon are among the names that we just read...We started today reflecting on a great hero of the past. The Artemis Generation are the heroes of American space exploration in the future," Pence said after he introduced the members of the Artemis Team during the eighth National Space Council meeting. The astronauts on the Artemis Team come from a diverse range of backgrounds, expertise and experience. Most of the astronauts in the group are in their 30s or 40s. The oldest is 55, the youngest 32. The agency's modern lunar exploration programme will land the first woman and next man on the Moon in 2024 and establish a sustainable human lunar presence by the end of the decade, NASA said. NASA will announce flight assignments for astronauts later, pulling from the Artemis Team. Additional Artemis Team members, including international partner astronauts, will join this group, as needed. "We are incredibly grateful for the president and vice president's support of the Artemis program, as well as the bipartisan support for all of NASA's science, aeronautics research, technology development, and human exploration goals," said NASA Administrator Jim Bridenstine. "As a result, we're excited to share this next step in exploration - naming the Artemis Team of astronauts who will lead the way, which includes the first woman and next man to walk on the lunar surface," he added. The selected astronauts will help NASA prepare for the coming Artemis missions, which begin next year working with the agency's commercial partners as they develop human landing systems; assisting in the development of training; defining hardware requirements; and consulting on technical development. They also will engage the public and industry on NASA''s exploration plans. "There is so much exciting work ahead of us as we return to the moon, and it will take the entire astronaut corps to make that happen," Chief Astronaut Pat Forrester said. "Walking on the lunar surface would be a dream come true for any one of us, and any part we can play in making that happen is an honour," he said. The other members on the list include Christina Koch and Jessica Meir -- the two astronauts who performed the world''s first all-female spacewalk last year.

Japan begins space capsule analysis hoping for asteroid sample

Japan begins space capsule analysis hoping for asteroid sample

Scientists in Japan on Tuesday began analysing a capsule sent back to Earth by a probe, hoping to find asteroid material that could offer clues on how the universe was formed.

Officials from Japan’s space agency said they were jubilant about the successful return of the capsule, which landed in Australia on Sunday after separating from the Hayabusa-2 probe.

“I’m genuinely appreciative of the fact that the capsule came back, after a 5.24 billion-kilometre round-trip,” project manager Yuichi Tsuda told reporters.

Scientists hope it will yield up to 0.1 grams of material collected from the asteroid Ryugu some 300 million kilometres from Earth — though they won’t know for sure until they look inside.

“I’m really looking forward to seeing (the samples) with my own eyes,” Tsuda said.

But that isn’t expected to happen before at least next week, with a series of steps required first to ensure the material is not contaminated.

For now, the capsule is “in a secure location” at a space centre in Sagamihara, south of Tokyo, agency director general Hitoshi Kuninaka said.

“Now we move to the matter-analysis phase,” he said. The samples — collected last year — are hoped to include both surface dust and pristine material stirred up when Hayabusa-2 fired an “impactor” into Ryugu.

Scientists hope they can shed light on how the formation of the universe unfolded, as well as on the origins of life on Earth.

The space agency has begun carefully processing the capsule, beginning by collecting gas inside. It will be opened later under strict conditions, including a nitrogen-filled box for the capsule.

“The key is that samples will not be polluted by Earth’s environment… so they can be provided to researchers around the world,” said Tomohiro Usui, leader of the extraterrestrial matter-analysis group.

“If we see something black inside the capsule, which is itself made of aluminium and whiteish, it’s near-certain it is from Ryugu,” he added. “But that is just supporting evidence, and we’ll not be able to say something for sure until we do chemical analysis.”

The nature of the gas extracted from the capsule also needs to be clarified, though officials said they believe it too was collected from the asteroid.

Half of Hayabusa-2’s samples will be shared between the Japanese space agency and other international organisations, while the rest will be kept for future study as advances are made in technology.The probe’s mission has been extended for more than a decade, with two new asteroids now being targeted for observation. Source: https://www.daily-bangladesh.com
