NASA's Orion capsule enters far-flung orbit around moon

NASA's Orion capsule entered an orbit stretching tens of thousands of miles around the moon Friday, as it neared the halfway mark of its test flight.

The capsule and its three test dummies entered lunar orbit more than a week after launching on the $4 billion demo that's meant to pave the way for astronauts. It will remain in this broad but stable orbit for nearly a week, completing just half a lap before heading home.

As of Friday's engine firing, the capsule was 238,000 miles (380,000 kilometers) from Earth. It's expected to reach a maximum distance of almost 270,000 miles (432,000 kilometers) in a few days. That will set a new distance record for a capsule designed to carry people one day.

"It is a statistic, but it's symbolic for what it represents," Jim Geffre, an Orion manager, said in a NASA interview earlier in the week. "It's about challenging ourselves to go farther, stay longer and push beyond the limits of what we've previously explored."

NASA capsule flies over Apollo landing sites, heads home

NASA's Orion capsule and its test dummies swooped one last time around the moon Monday, flying over a couple Apollo landing sites before heading home.

Orion will aim for a Pacific splashdown Sunday off San Diego, setting the stage for astronauts on the next flight in a couple years.

The capsule passed within 80 miles (130 kilometers) of the far side of the moon, using the lunar gravity as a slingshot for the 237,000-mile (380,000-kilometer) ride back to Earth. It spent a week in a wide, sweeping lunar orbit.

Once emerging from behind the moon and regaining communication with flight controllers in Houston, Orion beamed back photos of a close-up moon and a crescent Earth—Earthrise—in the distance.

"Orion now has its sights set on home," said Mission Control commentator Sandra Jones.

The capsule also passed over the landing sites of Apollo 12 and 14. But at 1,200 miles (1,900 kilometers) up, it was too high to make out the descent stages of the lunar landers or anything else left behind by astronauts more than a half-century ago. During a similar flyover two weeks ago, it was too dark for pictures. This time, it was daylight.

Deputy chief flight director Zebulon Scoville said nearby craters and other geologic features would be visible in any pictures, but little else.

Japanese company's lander rockets toward moon with UAE rover
https://phys.org/news/2022-12-japanese- ... ssion.html

A Tokyo company aimed for the moon with its own private lander Sunday, blasting off atop a SpaceX rocket with the United Arab Emirates' first lunar rover and a toylike robot from Japan that's designed to roll around up there in the gray dust.

It will take nearly five months for the lander and its experiments to reach the moon.

The company ispace designed its craft to use minimal fuel to save money and leave more room for cargo. So it's taking a slow, low-energy path to the moon, flying 1 million miles (1.6 million kilometers) from Earth before looping back and intersecting with the moon by the end of April.

By contrast, NASA's Orion crew capsule with test dummies took five days to reach the moon last month. The lunar flyby mission ends Sunday with a Pacific splashdown.

The ispace lander will aim for Atlas crater in the northeastern section of the moon's near side, more than 50 miles (87 kilometers) across and just over 1 mile (2 kilometers) deep. With its four legs extended, the lander is more than 7 feet (2.3 meters) tall.

NASA chief says U.S. will beat China in race to the moon

Bill Nelson decries Beijing's lack of transparency, praises Japan as a partner

When asked if the U.S. will reach the moon before China, NASA Administrator Bill Nelson said, "I think we will."


December 11, 2022 03:21 JST

WASHINGTON -- As the race between the U.S. and China to reach the moon intensifies, the head of NASA expects U.S. astronauts to land before their Chinese counterparts in 2025 or 2026.

"There are very, very few nations that do not want to be partners with us. China is one. China has always been very secretive," NASA Administrator Bill Nelson said in an interview with Nikkei, referring to Beijing's stance on developing its own project to send people to the moon. "I think we're in a race with China."
