US space agency NASA will host a media teleconference tonight on June 25 at 9 pm (IST) to provide updates on the Boeing crew flight test mission with Indian-American astronaut Sunita Williams and her colleague Butch Wilmore, who are facing some challenges aboard the International Space Station (ISS).
Williams and Wilmore are currently unable to return to Earth due to technical issues with the Boeing Starliner spacecraft.
The spacecraft, which was launched on June 5 as part of NASA's crew test flight, encountered several obstacles, delaying its safe return.
NASA’s briefing will offer the latest status on the astronauts' return and insights into the "ground hot fire testing" being conducted to ensure the Starliner's safe comeback.
NASA and Boeing engineering teams recently conducted hot fire testing of a Starliner reaction control system thruster at the White Sands Test Facility in New Mexico.
The test simulated various flight conditions, including the spacecraft's approach to the ISS and potential stress scenarios during undocking and deorbit burn.
According to NASA, “The test series involved firing the engine through similar in-flight conditions the spacecraft experienced during its approach to the space station.”
Williams’ return has been delayed multiple times due to several technical issues, including helium leaks, malfunctioning thrusters, and a faulty propellant valve.
Additionally, NASA's commercial crew manager, Steve Stich, explained, "Many of Starliner's thrusters have overheated when fired, and the leaks of helium, used to pressurise the thrusters, appear to be connected to how frequently they are used."
Meanwhile, during a previous press conference, Sunita Williams discussed the rigorous simulations they have undergone and their preparedness for any emergency.
She said, "We've been through a lot of simulations, and I think about where we are right now... I feel confident that if we had to, if there was a problem with the International Space Station, we could get into our spacecraft, undock, talk to our team and figure out the best way to come home."
Williams added, “I have a real good feeling in my heart that the spacecraft will bring us home, no problem.”
