A little more than two years ago, Dmitry Rogozin, the bellicose former head of Russia's space agency, nearly brought the International Space Station partnership to its knees.

During his tenure as director general of Roscosmos, Rogozin was known for his bombastic social media posts and veiled threats to abandon the space station after Russia's invasion of Ukraine. Russian President Vladimir Putin tersely dismissed Rogozin in July 2022 and replaced him with Yuri Borisov, a former deputy prime minister.

While the clash between Russia and Western governments over the war in Ukraine has not cooled, the threats against the International Space Station (ISS) ended. The program remains one of the few examples of cooperation between the US and Russian governments. Last year, Russia formally extended its commitment to the ISS to at least 2028. NASA and space agencies in Europe, Japan, and Canada have agreed to maintain the space station through 2030.

NASA astronauts Butch Wilmore and Suni Williams are no strangers to time away from their families. Both are retired captains in the US Navy, served in war zones, and are veterans of previous six-month stays on the International Space Station.

When they launched to the space station on Boeing's Starliner spacecraft on June 5, the astronauts expected to be home in a few weeks, or perhaps a month, at most. Their minimum mission duration was eight days, but NASA was always likely to approve a short extension. Wilmore and Williams were the first astronauts to soar into orbit on Boeing's Starliner spacecraft, a milestone achieved some seven years later than originally envisioned by Boeing and NASA.

However, the test flight fell short of all of its objectives. Wilmore and Williams are now a little more than three months into what has become an eight-month mission on the station. The Starliner spacecraft was beset by problems, culminating in a decision last month by NASA officials to send the capsule back to Earth without the two astronauts. Rather than coming home on Starliner, Wilmore and Williams will return to Earth in February on a SpaceX Dragon spacecraft.

Boeing's Starliner spacecraft sailed to a smooth landing in the New Mexico desert Friday night, an auspicious end to an otherwise disappointing three-month test flight that left the capsule's two-person crew stuck in orbit until next year.

Cushioned by airbags, the Boeing crew capsule descended under three parachutes toward an on-target landing at 10:01 pm local time Friday (12:01 am EDT Saturday) at White Sands Space Harbor, New Mexico. From the outside, the landing appeared just as it would have if the spacecraft brought home NASA astronauts Butch Wilmore and Suni Williams, who became the first people to launch on a Starliner capsule on June 5.

But Starliner's cockpit was empty as it flew back to Earth Friday night. Last month, NASA managers decided to keep Wilmore and Williams on the International Space Station (ISS) until next year after agency officials determined it was too risky for the astronauts to return to the ground on Boeing's spaceship. Instead of coming home on Starliner, Wilmore and Williams will fly back to Earth on a SpaceX Dragon spacecraft in February. NASA has incorporated the Starliner duo into the space station's long-term crew.

Boeing's Starliner spacecraft will gently back away from the International Space Station Friday evening, then fire its balky thrusters to rapidly depart the vicinity of the orbiting lab and its nine-person crew.

NASA asked Boeing to adjust Starliner's departure sequence to get away from the space station faster and reduce the workload on the thrusters to reduce the risk of overheating, which caused some of the control jets to drop offline as the spacecraft approached the outpost for docking in June.

The action begins at 6:04 pm EDT (22:04 UTC) on Friday, when hooks in the docking mechanism connecting Starliner with the International Space Station (ISS) will open, and springs will nudge the spacecraft away its mooring on the forward end of the massive research complex.

NASA is ready for Boeing's Starliner spacecraft, stricken with thruster problems and helium leaks, to leave the International Space Station as soon as Friday, wrapping up a disappointing test flight that has clouded the long-term future of the Starliner program.

Astronauts Butch Wilmore and Suni Williams, who launched aboard Starliner on June 5, closed the spacecraft's hatch Thursday in preparation for departure Friday. But it wasn't what they envisioned when they left Earth on Starliner three months ago. Instead of closing the hatch from a position in Starliner's cockpit, they latched the front door to the spacecraft from the space station's side of the docking port.

The Starliner spacecraft is set to undock from the International Space Station at 6:04 pm EDT (22:04 UTC) Friday. If all goes according to plan, Starliner will ignite its braking rockets at 11:17 pm EDT (03:17 UTC) for a minute-long burn to target a parachute-assisted, airbag-cushioned landing at White Sands Space Harbor, New Mexico, at 12:03 am EDT (04:03 UTC) Saturday.

NASA and Boeing are proceeding with final preparations to undock the Starliner spacecraft from the International Space Station next Friday, September 6, to head for landing at White Sands Space Harbor in southern New Mexico.

Astronauts Butch Wilmore and Suni Williams, who were supposed to return to Earth inside Starliner, will remain behind on the space station after NASA decided last week to conclude the Boeing test flight without its crew on board. NASA officials decided it was too risky to put the astronauts on Starliner after the spacecraft suffered thruster failures during its flight to the space station in early June.

Instead, Wilmore and Williams will come home on a SpaceX Dragon capsule no earlier than February, extending their planned stay on the space station from eight days to eight months. Flying on autopilot, the Starliner spacecraft is scheduled to depart the station at approximately 6:04 pm EDT (22:04 UTC) on September 6. The capsule will fire its engines to drop out of orbit and target a parachute-assisted landing in New Mexico at 12:03 am EDT (04:03 UTC) on September 7, NASA said in a statement Thursday.

Ten years ago next month, NASA announced that Boeing, one of the agency's most experienced contractors, won the lion's share of government money available to end the agency's sole reliance on Russia to ferry its astronauts to and from low-Earth orbit.

At the time, Boeing won $4.2 billion from NASA to complete the development of the Starliner spacecraft and fly a minimum of two, and potentially up to six, operational crew flights to rotate crews between Earth and the International Space Station (ISS). SpaceX won a $2.6 billion contract for essentially the same scope of work.

A decade later, the Starliner program finds itself at a crossroads after Boeing learned it will not complete the spacecraft's first Crew Flight Test with astronauts onboard. NASA formally decided Saturday that Butch Wilmore and Suni Williams, who launched on the Starliner capsule on June 5, will instead return to Earth in a SpaceX Crew Dragon spacecraft. Put simply, NASA isn't confident enough in Boeing's spacecraft after it suffered multiple thruster failures and helium leaks on the way to the ISS.

Senior NASA leaders, including the agency's administrator, Bill Nelson, will meet Saturday in Houston to decide whether Boeing's Starliner spacecraft is safe enough to ferry astronauts Butch Wilmore and Suni Williams back to Earth from the International Space Station.

The Flight Readiness Review (FRR) is expected to conclude with NASA's most consequential safety decision in nearly a generation. One option is to clear the Starliner spacecraft to undock from the space station in early September with Wilmore and Williams onboard, as their flight plan initially laid out, or to bring the capsule home without its crew.

As of Thursday, the two veteran astronauts have been on the space station for 77 days, nearly 10 times longer than their planned stay of eight days. Wilmore and Williams were the first people to launch and dock at the space station aboard a Starliner spacecraft, but multiple thrusters failed and the capsule leaked helium from its propulsion system as it approached the orbiting complex on June 6.

With no consensus on the safety of the Starliner crew capsule, NASA officials said Wednesday they need another week or two before deciding whether to bring two astronauts back to Earth on Boeing's spacecraft or extend their stay on the International Space Station until next year.

Boeing's Starliner spacecraft, stricken by suspect thrusters and helium leaks, is taking up a valuable parking spot at the space station. It needs to depart the orbiting research complex, with or without its two-person crew, before the launch of SpaceX's next Dragon crew mission to the station, scheduled for September 24.

"We can juggle things and make things work if we need to extend, but it’s getting a lot harder," said Ken Bowersox, associate administrator of NASA's spaceflight operations directorate. "With the consumables we’re using, with the need for the use of the ports for cargo missions, those types of things, we’re reaching a point where that last week in August, we really should be making a call, if not sooner.”

Boeing announced another financial charge Wednesday for its troubled Starliner commercial crew program, bringing the company's total losses on Starliner to $1.6 billion.

In its quarterly earnings report, Boeing registered a $125 million loss on the Starliner program, blaming delays on the spacecraft's still-ongoing Crew Flight Test, the program's first mission to carry astronauts into orbit. This is not the first time Boeing has reported a financial loss on Starliner. Including the new charge announced Wednesday, Boeing has now suffered an overall loss on the program of nearly $1.6 billion since 2016.

These losses have generally been caused by schedule delays and additional work to solve problems on Starliner. When NASA awarded Boeing a $4.2 billion contract to complete development of the Starliner spacecraft a decade ago, the aerospace contractor projected the capsule would be ready to fly astronauts by the end of 2017.

Sometime next year, SpaceX will begin returning its Dragon crew and cargo capsules to splashdowns in the Pacific Ocean and end recoveries of the spacecraft off the coast of Florida.

This will allow SpaceX to make changes to the way it brings Dragons back to Earth and eliminate the risk, however tiny, that a piece of debris from the ship's trunk section might fall on someone and cause damage, injury, or death.

"After five years of splashing down off the coast of Florida, we've decided to shift Dragon recovery operations back to the West Coast," said Sarah Walker, SpaceX's director of Dragon mission management.
