Two NASA astronauts may be looking at an unexpected eight-month stay on the International Space Station due to uncertainties surrounding the safety of Boeing's Starliner capsule. The astronauts, who were initially scheduled for a short trip, may have to switch to SpaceX for their return journey.
NASA officials expressed concerns over the safety of the Starliner capsule, leading to a potential decision to leave the astronauts on the space station while the capsule returns empty. This decision could also impact the upcoming SpaceX taxi flight in late September, with two seats reserved for the returning astronauts.
Additional experts are being brought in to investigate the thruster failures experienced by the Starliner, while Boeing works on modifying the capsule's software in case it returns without a crew. The company remains confident in the capsule's capabilities despite the ongoing issues.
Engineers are also addressing helium leaks in the Starliner's propulsion system, which are crucial for maneuvering the spacecraft. The challenges faced by Boeing highlight the importance of having multiple vehicles for crew transportation to the space station.
SpaceX, NASA's other commercial partner, has been delayed in its upcoming crew flight to allow for a resolution regarding the Starliner situation. The need for a backup taxi service was emphasized by NASA officials, underscoring the unpredictable nature of space missions.
As the space agency weighs its options, a final decision on the astronauts' return is expected by mid-August. The situation serves as a reminder of the complexities and uncertainties involved in human spaceflight missions.
