This week, NASA is sending up a rescue mission to the Worldwide Area Station.
On Thursday (Sept. 26), NASA astronaut Nick Hague and cosmonaut Aleksandr Gorbunov of Russia’s house company Roscosmos will launch to the Worldwide house Station (ISS) on SpaceX’s Crew-9 mission. Two different NASA astronauts, Zena Cardman and Stephanie Wilson, each mission specialists, had been presupposed to be aboard as properly.
However Wilson and Cardman had been reduce from the flight with a purpose to make room for 2 different NASA astronauts, Butch Wilmore and Suni Williams, who’re at the moment caught on the station and not using a devoted journey dwelling. The duo now will hitch a journey dwelling with Hague and Gorbunov when Crew-9 departs in February 2025, having spent roughly eight months in house. Williams and Wilmore had been presupposed to spend simply 10 days or so in house. How did NASA discover itself on this place?
Shortly after Wilmore and Williams launched on Crew Flight Check (CFT), the primary astronaut mission of Boeing’s Starliner spacecraft, on June 5, the capsule encountered points. 5 of its 28 reaction-control thrusters malfunctioned, and several other helium leaks had been detected within the spacecraft’s propulsion system.
NASA spent weeks diagnosing the problems by conducting assessments utilizing Starliner {hardware} on the White Sands Check Facility in New Mexico. Wilmore and Williams additionally carried out thruster assessments on the Starliner docked on the ISS to attempt to produce as a lot knowledge as potential for mission groups on the bottom to research with a purpose to decide if the automobile was a protected journey dwelling for astronauts.
“Our huge concern is having a profitable deorbit burn, ensuring that the [propellant] system works simply the way in which it must, during the deorbit burn,” stated Ken Bowersox, affiliate administrator for NASA’s Area Operations Mission Directorate, throughout an Aug. 14 briefing.
In the end, the house company introduced 10 days later that it had determined to deliver the automobile dwelling with out its crew. That left Starliner’s two astronauts, Williams and Wilmore, caught on the orbital outpost till they might hitch a journey dwelling on Crew-9.

Starliner’s first uncrewed flight check was equally unsuccessful. In December 2019, the spacecraft failed to succeed in the house station as a result of software program points. A second uncrewed orbital flight check in Might 2022 made it to the station and again simply fantastic, though eight months later than scheduled.
After CFT concluded with Starliner touchdown uncrewed within the New Mexico desert on Sept. 7, 2024, NASA leaders stated Wilmore and Williams would have been simply fantastic had they ridden it dwelling. “It could have been a protected, profitable touchdown with the crew on board,” stated Steve Stich, supervisor of NASA’s Industrial Crew Program, throughout a post-landing press convention earlier this month.
However, invoking classes discovered from the house shuttle Challenger and Columbia disasters, NASA harassed that it doesn’t wish to put astronauts in danger greater than is critical.
“The choice to maintain Butch and Suni aboard the Worldwide Area Station and convey the Boeing Starliner dwelling uncrewed is a results of a dedication to security,” NASA Administrator Invoice Nelson informed reporters on Aug. 24.
“NASA, ever since, has tried very onerous to result in an environment through which individuals are inspired to step ahead and converse their thoughts, and I feel, proper, right this moment is an efficient instance of that,” Nelson stated.

NASA was in an analogous place simply final 12 months. Astronaut Frank Rubio was stranded on the ISS when a violent coolant leak popped up on the Russian Soyuz MS-22 spacecraft he rode to the ISS as a part of the Expedition 68 mission.
Rubio would go on to spend 371 steady days in house, breaking a U.S. report whereas he waited on a substitute Soyuz for a journey dwelling.
Other than being a “rescue mission” of types, Crew-9 will probably be historic for various different causes. It is going to be the primary crewed launch to take off from Area Launch Complicated-40 (SLC-40) at Cape Canaveral Area Pressure Station in Florida, and solely the second crewed launch from the Area Pressure web site total, following Starliner’s CFT launch in June.
Crew-9 commander Nick Hague can even grow to be the primary energetic U.S. Area Pressure Guardian to launch to house because the department was established in 2019.
