NASA astronauts Barry “Butch” Wilmore and Sunita “Suni” Williams have had a little bit of a protracted journey to house. Since their blast off on June 5 aboard the Boeing Starliner from Florida’s House Coast, the astronauts have been staying on the Worldwide House Station (ISS) alongside the Expedition 71 crew after points arose with the craft.
Earlier than Wilmore and Williams arrived on the ISS, the Starliner craft noticed 5 of its small thrusters fail and a helium leak. The problems postponed indefinitely the astronauts’ return to Earth — initially deliberate for one week after launch.

Sizzling hearth take a look at
Numerous groups are working towards bringing Wilmore and Williams again to Earth. On July 27, NASA and Boeing accomplished a second docked Starliner sizzling hearth take a look at. The take a look at was to evaluate the craft’s propulsion system. Each Wilmore and Williams had been seated within the spacecraft as a part of the take a look at, which was meant to permit NASA and Boeing groups to judge the helium provide and leak charges.
Throughout the take a look at, 27 of the spacecraft’s 28 jets had been fired one after the other in brief bursts. The thruster efficiency and helium leak charges had been assessed for every jet in flip. In accordance with the NASA Business Crew Program blog: “Preliminary outcomes present all of the examined thrusters are again to preflight ranges based mostly on thrust and chamber stress.”
On Aug. 1 and 6, subsequent blog posts said that NASA and Boeing’s groups had been nonetheless assessing the outcomes of the take a look at, with the aim of confirming the system’s reliability for the Starliner spacecraft’s return to Earth. The Aug. 6 put up additionally said that NASA and SpaceX are actually aiming for a launch of the Crew-9 mission to the ISS no sooner than Sept. 24. (The launch was initially slated for Aug. 18.) “This adjustment permits extra time for mission managers to finalize return planning for the company’s Boeing Crew Flight Take a look at at present docked to the orbiting laboratory,” the post reads.
Six craft are at present docked to the station, together with the Starliner, a number of resupply ships, a Soyuz capsule for the Russian crew, and the SpaceX Crew Dragon Endeavour. The ISS has solely two docking ports designed to accommodate both SpaceX or Boeing’s crewed capsules, each of which are actually occupied.
Different choices open
As of an replace with the media this morning, NASA has nonetheless not set a return date for the astronauts.
Moreover, officers famous they “produce other choices open,” in keeping with Steve Stich, program supervisor for NASA’s Business Crew Program. “We have now been working with SpaceX to make sure they’re prepared to reply with Crew-9 as a contingency,” he mentioned.
If that had been the case, NASA would ship solely two of 4 deliberate astronauts up within the SpaceX Dragon capsule designated for the mission. Wilmore and Williams would take the 2 empty seats on the craft’s return — in February 2025.
If Williams and Wilmore hitch a journey on a SpaceX craft, the Starliner may very well be returned to Earth uncrewed.
“Boeing stays assured within the Starliner spacecraft and its capacity to return safely with crew. We proceed to assist NASA’s requests for extra testing, information, evaluation, and evaluations to affirm the spacecraft’s protected undocking and touchdown capabilities. Our confidence relies on this abundance of beneficial testing from Boeing and NASA,” Boeing mentioned in a press release.
