Washington DC [US], US space agency NASA on Thursday announced that the first crewed launch of Boeing's Starliner spacecraft, piloted by Indian-origin Suneet Williams, to the International Space Station (ISS) has now been scheduled for June 1, according to NASA mission managers. Is being targeted for. Boeing and ULA (United Launch Alliance) continue to evaluate a path forward for launching the Boeing Crew Flight Test (CFT) to the International Space Station (ISS), the space agency said in a statement. The teams are now working towards launch. The spacecraft's first mission to carry humans was delayed due to a helium leak on Starliner's service module, with additional opportunities scheduled for 12:25 p.m. ET on Saturday, June 1, June 2, June 5, and June 6. Which was initially planned for May but was pushed forward. Boeing's Stalingrad spacecraft is designed to carry Sunita 'Sunny' Williams and fellow NASA astronaut Barry 'Butch' Wilmore to the International Space Station as part of a final test run before the US The space agency could certify Starliner for routine missions.The ISS Starliner spacecraft will be launched into space aboard rocket company United Launch Alliance (ULA)'s Atlas 5 rocket from the Cape Canaveral Space Force Station in Florida. The pair will stay in the orbiting laboratory for about two weeks to evaluate the new spacecraft and its systems before returning to Earth in the western United States. NASA, Boeing and ULA teams will replace the Centaur sail regulating valve and troubleshoot the Starliner service module helium manifold leak,” said Steve Stich, manager of the NASA Commercial Crew Program. "It is important that we take our time to understand all the complexities of each issue, including redundant capabilities of the Starliner propulsion system and any impact on our interim human rating certification," he said in a statement released by the US space agency. "We will launch Butch and Suni on this test mission after the entire community reviews the teams' progress and flight logic at the upcoming Delta Agency Flight Test Readiness Review," he said as Sunita Williams and Barry Wilmore both practiced in the Starline simulator and the crew will continue.The one set aside will fly to NASA's Kennedy Space Center in Florida near the new launch date, the space agency said, with mission managers for the Boeing Starliner's Crewed Test Flight (CFT) on May 7, just two hours ahead of schedule. Called the mission. The launch occurred due to a valve malfunction in the upper stage of the Atlas 5 rocket. Boeing said in its statement that the valve was successfully replaced on May 11 and tested to confirm that it was functioning properly. Later on May 14, NASA announced that the CFT mission was scheduled for May. On May 17, the launch was pushed back to May 21 due to what was described as a "small Helium leak" in the spacecraft's service module. On May 17, the space agency said the launch had been pushed back to 25 Ma, The flight of Starliner marked Boeing's first spacecraft mission with a Huma crew, part of NASA's Commercial Crew Program, a public-private partnership to launch astronauts or American rockets and spacecraft from U.S. soil. Through US work with the aerospace industry, NASA selected Boeing and SpaceX in September 2014 for the transport.Crew from the United States to the International Space Station. These integrated spacecraft rockets and associated systems will carry four astronauts on NAS missions, maintaining a space station crew of seven to devote maximum time to scientific research on the orbiting laboratory. After a failed attempt in December 2019, Boeing conducted a successful uncrewed orbital flight. Test 2 (OFT-2) in 2022. Its Starliner is expected to be reusable for ten missions within a six-month turnaround time, with aerospace giant Elon Musk-owned SpaceX company's Crew Dragon having performed 12 crewed missions since then.First launch on May 30, 2020 Boeing received more than US$4 billion in US federal funds to develop Starliner, while SpaceX received approximately US$2.6 billion.
