Two astronauts are stranded on an area station, and their spacecraft — with no crew — left them there and returned to Earth.
It sounds just like the pitch for a creepy science-fiction or horror film, however that is the state of affairs that unfolded late Friday when Boeing’s Starliner capsule left astronauts Sunita “Suni” Williams and Barry “Butch” Wilmore on the Worldwide House Station and efficiently landed at White Sands House Harbor in New Mexico.
However for the 2 seasoned astronauts caught on the ISS, the scenario is not almost as Hollywood-scary because it sounds. Let’s break it down.
Who’re the astronauts?
Wilmore, 61, and Williams, 58, are veteran astronauts, each naval officers and former check pilots. Williams has been a NASA astronaut since 1998, and Wilmore since 2000. Each have loads of expertise in area.
Williams is the previous file holder for many spacewalks by a lady (seven) and most spacewalk time for a lady (50 hours, 40 minutes), and in 2007, she ran the primary marathon by any particular person in area.
In 2009, Wilmore piloted the House Shuttle Atlantis on its mission to the ISS, and in 2014, he was a part of the ISS crew that used a 3D printer to fabricate a device — a ratchet wrench — in area, the primary time people manufactured one thing off-world.
What’s their mission in area?
Wilmore, as commander, and Williams, as pilot, traveled to the ISS on a 15-foot-wide, Boeing-made capsule known as Starliner. They launched on June 5 and docked with the ISS on June 6. NASA hopes Starliner will give the group a brand new option to get crews to and from the ISS, and the truth that it is Boeing-made is one other signal that NASA is beginning to lean on the non-public sector for its human spaceflight choices, The New York Instances reported.
Wilmore and Williams’ ISS mission was presupposed to final a mere eight days, throughout which they’d check out elements of Starliner and see the way it operates with a human crew in area. However on account of issues with Starliner, the 2 astronauts are nonetheless up there and will not be again earlier than 2025. They’ve saved busy — working with the ISS Expedition 71 crew to carry out analysis and upkeep actions, NASA said.
How did they get caught in area?
The Starliner was delayed in Could on account of an issue with a valve within the rocket. Then engineers needed to repair a helium leak. That is all dangerous information for Boeing, which is competing with SpaceX, which has been transporting astronauts to the ISS since 2020, making over 20 profitable journeys to the area station.
Starliner lastly launched, atop an Atlas V rocket, on June 5, however some issues got here together with it. NASA introduced that three helium leaks had been recognized, one among which was recognized earlier than flight, and two new ones. Along with the leaks, the crew needed to troubleshoot failed management thrusters, although the craft was in a position to efficiently dock with the ISS.
SpaceX has had failures too. A Falcon 9 rocket exploded on the launchpad in 2016. In July, a Falcon 9 rocket skilled a liquid oxygen leak and deployed its satellites within the mistaken orbit, The New York Instances reported. And a Falcon 9 rocket final week misplaced a first-stage booster when it toppled over into the Atlantic Ocean and caught fire.
However that mentioned, SpaceX has greater than 300 profitable Falcon 9 flights to its credit score.
The astronauts are secure
NASA has been fast to report that the astronauts aren’t at risk, nor are they completely caught.
“There isn’t any rush to carry (the) crew house,” NASA said in a press release final month. “It is a lesson realized from the area shuttle Columbia accident. Our NASA and Boeing groups are poring over knowledge from further in-space and floor testing and evaluation, offering mission managers knowledge to make the very best, most secure resolution on how and when to return crew house.”
On Aug. 24, a choice was reached.
When and the way are the astronauts coming house?
NASA mentioned on Aug. 24 that it had determined to return Starliner to Earth with no crew, and the spacecraft landed safely in New Mexico on Sept. 6.
Wilmore and Williams will probably be introduced house house on the SpaceX Crew-9 Dragon spacecraft early subsequent yr.
“Wilmore and Williams will proceed their work formally as a part of the Expedition 71/72 crew via February 2025,” the area company said in a press release. “They may fly house aboard a Dragon spacecraft with two different crew members assigned to the company’s SpaceX Crew-9 mission.”
That mission will launch no ahead of Sept. 24, NASA mentioned. 4 crew members had been initially scheduled to be on board at launch, however two will now keep behind to make room for Wilmore and Williams’ return journey.
“Spaceflight is dangerous, even at its most secure and most routine,” NASA Administrator Invoice Nelson mentioned in a press release on Aug. 24. “A check flight, by nature, is neither secure, nor routine. The choice to maintain Butch and Suni aboard the Worldwide House Station and produce Boeing’s Starliner house uncrewed is the results of our dedication to security: our core worth and our North Star.”
What are the astronauts saying?
The astronauts are not panicking.
“We’re having a good time right here on ISS,” Williams mentioned in a news conference held from orbit in July. “I am not complaining. Butch is not complaining that we’re up right here for a few additional weeks.”
And regardless of the Starliner issues, Wilmore appears optimistic concerning the craft.
“The spacecraft carried out unbelievably effectively,” he mentioned, though noting that the thruster issues of the second day had been apparent. “You would inform the thrust management, the aptitude was degraded,” he mentioned.
On Aug. 24, Norman Knight, the chief of NASA’s flight director workplace, mentioned he’d spoken with the 2 astronauts concerning the resolution to return them on the SpaceX Crew-9 Dragon early subsequent yr, The New York Instances reported.
“They assist the company’s resolution absolutely,” Knight mentioned, in response to the Instances, “and so they’re able to proceed this mission onboard ISS.”
