After Butch Wilmore obtained settled into the commander seat of Starliner earlier this summer time, he thanked the folks getting ready to blast him and his crewmate Suni Williams into area. 

“Excellent. Good job, guys,” the NASA astronaut mentioned earlier than a launch try that finally scrubbed. “We’ll see you in a few weeks — or longer.” 

The launch commentators had been amused. 

“Butch, planning on staying up there longer,” mentioned Jim Could, a Boeing engineer, restating Wilmore’s radio communication. “Possibly he’ll do a few additional guide piloting demos whereas he is round there.” 

A couple of days later, the 2 astronauts certainly launched to the Worldwide House Station, and people earlier phrases reveal their frame of mind earlier than the flight: They knew their deliberate week in area could be greater than that. However the phrases additionally foreshadowed the remainder of the tortuous mission. 

For greater than two months, Wilmore and Williams have been in limbo 250 miles above Earth. Starliner, the brand new Boeing spaceship they test-piloted, skilled elusive propulsion points on the journey. Now the U.S. area company should resolve whether or not to ship them house of their take a look at capsule or make sophisticated preparations for them to experience a distinct spaceship — one constructed and managed by Boeing’s competitor, SpaceX. Boeing, for its half, firmly believes Starliner can deal with the job.

Switching to SpaceX’s Crew Dragon just isn’t a super answer for NASA, both. The change would have a cascading impact on launch pads and the flight schedule. 

“We’re reaching a degree the place that final week in August, we actually ought to be making a name, if not sooner,” mentioned Ken Bowersox, NASA’s affiliate administrator of area operations.

Apart from the final concern for Wilmore and Williams’ well being — their our bodies obtain extra radiation and bone deterioration in area — the company faces a ticking clock with the manifest.

The U.S. section of the area station has 4 ports — two for spaceships and two for cargo freighters. Proper now one SpaceX capsule and Starliner occupy each crew docks. There is not any interoperability between U.S. ships and Russian ports, and cargo spots aren’t geared up for passenger craft. In brief, the parking zone is full. 

NASA already postponed the subsequent crew rotation one month to purchase a while to determine the trail ahead for Starliner, however the delayed SpaceX capsule will probably be on its strategy to the station on Sept. 24. Starliner must undock earlier than then, whether or not with human pilots or robotically, to accommodate the opposite SpaceX spaceship. 

Along with logistics on the station, NASA has needed to think about how adjustments would have an effect on operations on the bottom. By delaying the subsequent SpaceX Crew-9 flight, for instance, the company has needed to scramble to get certification to maneuver the launch to a distinct pad at Kennedy House Heart in Florida. In any other case, Crew-9 would intrude with preparations for the launch of Europa Clipper, a robotic science mission set to review considered one of Jupiter’s moons. 

All of the shuffling leaves a reasonably tight window in September for Starliner to depart. If NASA chooses to not ship the Starliner astronauts house in Starliner, they will stay on the station till February 2025, turning their unique eight-day go to into an eight-month layover.

“In some unspecified time in the future, we have to convey these people house, and get again to a standard crew measurement on the ISS,” Bowersox mentioned. 

Although astronauts are skilled for unanticipated adjustments in departures and arrivals, an prolonged keep in area will imply the 2 will probably be separated from their households for greater than half a yr.

Even astronauts, who’re typically considered as superhuman, can succumb to the tedium of life away from Earth. NASA astronaut Frank Rubio, who just lately spent 371 days on the area station as a result of his Russian experience house sprung a coolant leak, mentioned it was a demanding ordeal. 

“The psychological issue was extra of an element than I anticipated,” he mentioned then.

Wilmore and Williams have been put to work since they arrived. Along with diagnostic exams on Starliner, they’ve assisted in different methods on the orbiting laboratory. Each have taken up deferred upkeep duties — reminiscent of assembling a backup urine processor dubbed “Frankenpump” — that at instances have made them seem to be glorified area janitors. 

Having additional crew readily available to choose up slack has been a perk for NASA, nevertheless it additionally has its drawbacks. Extra folks in orbit means additional mouths to feed, and further carbon dioxide to filter out of the air. Time on train machines must be meticulously managed to make sure everybody stays match within the weightless setting. 

Getting Starliner via the testing part has been a relentless battle for Boeing, although its representatives haven’t at all times been forthcoming on why this system has suffered so many setbacks. A string of points has spanned a decade. 

After the House Shuttle retired in 2011, NASA hitched all of its rides on Russian rockets to the area station, costing the US tens of tens of millions of {dollars} per experience. Some thought of it a nationwide embarrassment.

NASA employed Boeing and SpaceX to construct business spaceships to hold astronauts to and from the station in 2014. Whereas SpaceX’s capsule went into service 4 years in the past, Boeing’s Starliner has but to acquire certification for normal flight operations. NASA by no means supposed to have all its eggs in Elon Musk‘s basket and says Starliner continues to be essential to have as a backup. 

In a U.S. Securities and Alternate Fee submitting, Boeing mentioned Starliner’s issues value the corporate $125 million within the final quarter, with a probability that it might “document further losses in future intervals.”

When requested which means Wilmore and Williams’ wished to journey again to Earth, Joe Acaba, NASA’s chief astronaut, mentioned it wasn’t as much as them. 

“This isn’t actually a desire factor,” he informed reporters on Aug. 14. “They will anticipate us to research the information and to give you the choice, and, once more, they may do what we ask.”
