Russia will launch new capsule to return space station crew
Russia will send up a new capsule next month to bring back three space station crew members whose original ride home was damaged, officials said Wednesday.
The two Russians and one American will stay several extra months at the International Space Station as a result of the capsule switch, possibly pushing their mission to close to a year, NASA and Russian space officials told reporters.
Cosmonauts Sergey Prokopyev and Dmitri Petelin, and astronaut Frank Rubio were supposed to return in March in the same Soyuz capsule that took them up last September. But that capsule was hit by a tiny meteoroid on Dec. 14, creating a small hole in the exterior radiator and sending coolant spewing into space.

Sergei Krikalev, head of human spaceflight for the Russian Space Agency, said barring an emergency at the space station, it would be too dangerous for the crew to use that capsule to return to Earth.
Although Russian engineers believe the capsule could survive reentry and land safely, the cabin temperature could reach the low 40s Celsius (over 100 degrees Fahrenheit) with high humidity because it couldn't shed heat generated by a computer and other electronics, noted Krikalev, a former cosmonaut.
The new Soyuz capsule will be launched from Kazakhstan on Feb. 20, a month earlier than planned. No one will be on board; the capsule will fly in automatic mode, Russian Space Agency chief Yuri Borisov announced earlier in the day. The original plan was to launch this new Soyuz in March with two Russians and one American, replacements for the three already up there. This new crew will now have to wait until late summer or fall to fly when another capsule is ready for them.
Russia will eventually bring back the damaged capsule with only science samples on board.
NASA took part in all the discussions and agreed with the plan.
“Right now, the crew is safe on board space station,” said NASA's space station program manager Joel Montalbano. “There’s no immediate need for the crew to come home today.”
Backup plans are in the works, according to Montalbano and Krikalev, in case an emergency forces the seven space station residents to flee before the new Soyuz can be launched — like a fire or decompression. NASA is looking at the possibility of adding extra crew to the SpaceX capsule currently docked at the station.

Neither Krikalev nor Montalbano could recall a similar case in which a substitute spacecraft needed to be quickly launched.
Borisov said analysis confirmed the leak was caused by a micrometeoroid, not a piece of spacecraft debris or manufacturing defect. The resulting hole was about 1 millimeter in size or less than one-tenth of an inch.
Montalbano said the three crew members took the news in stride.
“I may have to find some more ice cream to reward them" on future cargo deliveries, he told reporters.
Besides Prokopyev, Petelin and Rubio, the space station is home to NASA astronauts Nicole Mann and Josh Cassada; Russian Anna Kikina and Japan's Koichi Wakata. The four rode up on a SpaceX capsule last October.

Boeing capsule lands back on Earth after space shakedown
Boeing’s crew taxi returned to Earth from the International Space Station on Wednesday, completing a repeat test flight before NASA astronauts climb aboard.
It was a quick trip back: The Starliner capsule parachuted into the New Mexico desert just four hours after leaving the orbiting lab, with airbags attached to cushion the landing. Only a mannequin was buckled in.
Aside from thruster failures and cooling system snags, Starliner appeared to clinch its high-stakes shakedown cruise, 2 1/2 years after its botched first try. Flight controllers in Houston applauded and cheered the bull’s-eye touchdown.
“It’s great to have this incredible test flight behind us,” said Steve Stich, director of NASA’s commercial crew program. He described the demo as “extremely successful,” with all objectives met.

Added Boeing’s Mark Nappi, a vice president: “On a scale of one to 10, I think I’d give it a 15.”
Based on these early results, NASA astronauts will strap in next for a trip to the space station, perhaps by year’s end. The space agency has long wanted two competing U.S. companies ferrying astronauts, for added insurance as it drastically reduced its reliance on Russia for rides to and from the space station.
Elon Musk’s SpaceX is already the established leader, launching astronauts since 2020 and even tourists. Its crew capsules splash down off the Florida coast, Boeing’s Starliner returns to the Army’s expansive and desolate White Sands Missile Range in New Mexico.
Boeing scrapped its first attempt to reach the space station in 2019, after software errors left the capsule in the wrong orbit and nearly doomed it. The company fixed the flaws and tried again last summer, but corroded valves halted the countdown. Following more repairs, Starliner finally lifted off from Cape Canaveral last Thursday and docked to the space station Friday.
Station astronauts tested Starliner’s communication and computer systems during its five days at the space station. They also unloaded hundreds of pounds (kilograms) of groceries and other supplies that flew up in the Boeing capsule, then filled it with empty air tanks and other discarded gear.
A folded U.S. flag sent up by Boeing stayed behind, to be retrieved by the first Starliner crew.
“We’re a little sad to see her go,” station astronaut Bob Hines radioed as the capsule flew away.
Along for the ride was Starliner’s test dummy — Rosie the Rocketeer, a takeoff on World War II’s Rosie the Riveter.
The repairs and do-over cost Boeing nearly $600 million.
