After being stranded on the Worldwide Area Station since June, two astronaut castaways should be months away from returning to Earth—partly due to incompatible spacesuits.
The 2 astronauts, Butch Wilmore and Suni Williams, have needed to prolong what was presupposed to be an eight-day journey on the ISS, on account of a helium leak and thruster malfunctions on their Boeing-made Starliner spacecraft. NASA and Boeing are testing to see if it’s protected for the astronauts to return on the Boeing Starliner, however are additionally contemplating alternate options due to the doable dangers.
NASA has but to decide, however a kind of alternate options consists of sending the astronauts house on a Dragon spacecraft, manufactured by Elon Musk’s SpaceX, that’s already docked on the station, a consultant from the area company mentioned throughout a press convention final week, Ars Technica reported.
But, that strategy comes with issues, as defined by Swapna Krishna, the journalist behind the space-themed YouTube channel Advert Astra. If NASA selected that possibility, Wilmore and Williams can be the fifth and sixth astronauts on a spacecraft that’s restricted to 4 passengers. And since their Starliner fits aren’t suitable with the Dragon spacecraft, they must return to Earth with out fits on, which isn’t inherently harmful, however gives them much less safety in case one thing goes unsuitable with the capsule.
The differing go well with designs and plugs for the Starliner and Dragon spacecrafts comes all the way down to a brand new course of for industrial crewed area missions that NASA has carried out. Beforehand, NASA was extraordinarily concerned within the manufacture and testing of spacecraft and spacesuits.
But, for the reason that 2010s when NASA developed the industrial crew program, it has given non-public firms extra freedom in how they develop and manufacture gear for the company, together with spacesuits, so long as it meets broad security necessities. As an example, NASA didn’t specify that spacesuits for every industrial spacecraft should be cross suitable with one another. The truth is, having two completely different go well with designs for every spacecraft may be useful, based on Krishna.
“If the fits used the identical kind of plug and a few type of flaw was discovered inside that plug or another type of standardized connector, it could floor each spacecraft,” she mentioned in a Sunday video.
A spokesperson for Boeing referred a request for remark to NASA. NASA and SpaceX didn’t instantly reply to requests for remark. NASA has mentioned the astronauts are not “stranded” on the ISS.

One other different is sending the astronauts house on a special Dragon spacecraft that’s set to succeed in the ISS in September. This ship might attain the area station with solely two of its standard 4 crew members and will ship up additional (Dragon-compatible) spacesuits, which might enable Wilmore and Williams to return to Earth totally suited within the two unfilled seats.
But when NASA selected this different, the Starliner ship that the astronauts initially flew in must undock and return to Earth autonomously to make room for the Dragon spacecraft arriving in September, and Boeing has mentioned it may not be capable of do this. Due to the best way Boeing’s contract with NASA is structured, the corporate has needed to take up the additional prices related to the technical failures of its Starliner. The corporate has already taken about $1.6 billion in expenses on its Starliner program.
If the Starliner left the area station and not using a crew, the astronauts on the ISS would even have to put in two additional seats on the remaining Dragon spacecraft till the subsequent Dragon spaceship arrives, as a result of there must be sufficient seats on the remaining docked ship to accommodate all of the NASA astronauts in case of an emergency.
The marooned astronauts would additionally have to take the place of the 2 astronauts pulled from the Dragon mission to accommodate them, which might maintain them aboard the ISS till the common rotation ends in February 2025. That will imply turning what was presupposed to be simply over a week-long mission into eight months. Though each astronauts have accomplished longer missions on the ISS earlier than, these had been stuffed with much less uncertainty. Wilmore’s spouse instructed a CBS station in Knoxville, Tenn. that she is getting ready for her husband to miss Christmas and the couple’s thirtieth marriage ceremony anniversary.
