• Boeing's Starliner spacecraft is set to make its first crewed flight this week, with two more opportunities to launch after an initial attempt was postponed. The uncrewed Starliner spacecraft successfully docked with the International Space Station in May 2022, a crucial milestone after a failed attempt in 2019. The upcoming crewed flight will be a critical test for the Starliner, which is designed to transport astronauts to and from the ISS as part of NASA's Commercial Crew Program.

• The Starliner's launch window opens on July 21st and closes on July 25th, with backup opportunities on July 26th and July 27th. The spacecraft will carry two NASA astronauts, Barry "Butch" Wilmore and Suni Williams, on a mission to the ISS that is expected to last around a week. This mission will be the final step in the Starliner's certification process, paving the way for regular crew rotations between Earth and the space station.

• The Starliner's successful crewed flight will be a significant achievement for Boeing, which has faced setbacks and delays with the spacecraft's development. The company is competing with SpaceX's Crew Dragon to provide NASA with a reliable and cost-effective way to transport astronauts to the ISS, reducing the agency's reliance on Russian Soyuz rockets. The Starliner's performance during this upcoming mission will be closely watched by the space industry and the public as it aims to demonstrate its capabilities and reliability.
