NASA Postpones Return of Stranded Starliner Astronauts to March

NASA has again postponed the instrumentality to Earth of Barry Wilmore and Sunita Williams, the astronauts stranded connected the International Space Station aft Boeing's Starliner capsule malfunctioned successful the mediate of this year.

The unit of the spacecraft arrived astatine the ISS successful June. The nonsubjective was to trial the Starliner’s broad capabilities, including launch, docking, and instrumentality systems. The ngo was scheduled to past 1 week. Five of the capsule’s 28 thrusters failed to relation earlier docking with the ISS. Boeing claimed that its exertion could warrant the harmless instrumentality of the astronauts. However, NASA expressed doubts and concluded that the hazard was excessively high. The bureau entrusted the task to SpaceX.

Elon Musk's institution launched the Crew-9 ngo successful September to, among different things, instrumentality Williams and Wilmore. Until now, the stalled astronauts were scheduled to return successful February aboard the Crew Dragon rocket. However, NASA has announced that it expects the expedition to instrumentality to Earth's aboveground aft the accomplishment of Crew-10, which volition beryllium sent successful precocious March 2025 astatine the earliest.

The accommodation volition let SpaceX and NASA engineers to finalize improvement of a caller Dragon spacecraft, which volition beryllium shipped to the company's Florida installation aboriginal adjacent month.

"Fabrication, assembly, testing, and last integration of a caller spacecraft is simply a painstaking endeavor that requires large attraction to detail,” said Steve Stich, manager of NASA’s Commercial Crew Program, successful a statement. “We admit the hard enactment by the SpaceX squad to grow the Dragon fleet successful enactment of our missions and the flexibility of the presumption programme and expedition crews arsenic we enactment unneurotic to implicit the caller capsule’s readiness for flight.”

NASA said that Crew-9 and Crew-10 crews indispensable implicit a “handover period,” during which the ISS residents stock experiences and cognition with the caller arrivals. This process ensures the due show of onboard subject experiments and attraction of the orbital complex.

NASA and SpaceX specialists evaluated respective options for coordinating the adjacent crewed delivery. They determined that the March motorboat for Crew-10 was the “best enactment for gathering NASA’s requirements and achieving abstraction presumption objectives for 2025,” according to an bureau property release.

A Long Haul

The ISS received 2 resupply flights successful November, ensuring that the unit members person capable food, water, clothing, and oxygen. However, immoderate experts person warned of imaginable wellness risks for Wilmore and Williams aft spending much than 9 months successful space.

The technological assemblage has been studying the effects of spaceflight connected the quality assemblage since the 1970s. In the years since the archetypal lunar landing, it has identified conditions specified arsenic nonaccomplishment of bony mass, weakened bosom function, ocular problems, and the improvement of kidney stones.

A caller survey from University College London reveals that the operation and relation of the kidneys tin besides endure imperishable damage, though this is peculiarly assertive successful cases of astronauts who get excessively acold distant from Earth, which is not the lawsuit connected the ISS.

NASA points retired that the crews of expeditions to the ISS usually marque extended stays, with an mean duration of six months. It adds that immoderate astronauts person carried retired missions of up to 1 twelvemonth to lend to probe connected quality adaptation to spaceflight, with a presumption to aboriginal lunar and Martian exploration.
