NASA and Boeing proceed evaluating Starliner for its return to Earth and are contemplating reserving seats for Wilmore and Williams on the upcoming Crew-9 mission.

NASA astronauts Barry “Butch” Wilmore and Sunita “Suni” Williams have had a little bit of a chronic journey to area. Since their blast off on June 5 aboard the Boeing Starliner from Florida’s Area Coast, the astronauts have been staying on the Worldwide Area 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.

Scorching hearth check
Varied groups are working towards bringing Wilmore and Williams again to Earth. On July 27, NASA and Boeing accomplished a second docked Starliner scorching hearth check. The check was to evaluate the craft’s propulsion system. Each Wilmore and Williams have been seated within the spacecraft as a part of the check, which was meant to permit NASA and Boeing groups to judge the helium provide and leak charges.
Through the check, 27 of the spacecraft’s 28 jets have been fired one after the other in brief bursts. The thruster efficiency and helium leak charges have been assessed for every jet in flip. In response to the NASA Business Crew Program weblog: “Preliminary outcomes present all of the examined thrusters are again to preflight ranges primarily based on thrust and chamber strain.”
On Aug. 1 and 6, subsequent weblog posts acknowledged that NASA and Boeing’s groups have been nonetheless assessing the outcomes of the check, with the objective of confirming the system’s reliability for the Starliner spacecraft’s return to Earth. The Aug. 6 put up additionally acknowledged that NASA and SpaceX at the moment are 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 presently docked to the orbiting laboratory,” the put up reads.
Six craft are presently 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 at the moment are 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 line 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 stated.
If that have 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 experience on a SpaceX craft, the Starliner might be returned to Earth uncrewed.
“Boeing stays assured within the Starliner spacecraft and its capability to return safely with crew. We proceed to assist NASA’s requests for added testing, information, evaluation, and critiques to affirm the spacecraft’s protected undocking and touchdown capabilities. Our confidence relies on this abundance of priceless testing from Boeing and NASA,” Boeing stated in a press launch.
