What To Know
- If this flange is leaking, it means that there is a problem with the sealing of the connection between the flange and the thrusterwhich can cause a loss of pressure in the propulsion system.
- While this anomaly is unlikely to pose a major risk on the ground, it must be resolved to ensure the propulsion system operates properly in orbit.
- The launch date is now set for May 21stand not at 17 as expected recentlyThe delay is the latest in a series of technical setbacks that have plagued Boeing’s Starliner program.
Boeing has decided to take a few extra days to fix a helium leak on its Starliner spacecraft, delaying the first crewed launch with NASA astronauts on board. The leak, while considered minor, requires immediate attention to ensure the safety and reliability of the flight. With this decision, the launch is now scheduled for May 21.
Boeing faces new technical glitch
This leakage problem has been attributed to a bridle on a thruster of the unique reaction control system of the spacecraft service module. In detail, this part is used in this context to fix or connect two elements together in a safe and watertight manner. Here, it integrates the system that controls the trajectory and orientation of the spacecraft in orbit. If this flange is leaking, it means that there is a problem with the sealing of the connection between the flange and the thrusterwhich can cause a loss of pressure in the propulsion system. While this anomaly is unlikely to pose a major risk on the ground, it must be resolved to ensure the propulsion system operates properly in orbit. Boeing engineers are currently working on solutions to address this situation. The launch date is now set for May 21stand not at 17 as expected recentlyThe delay is the latest in a series of technical setbacks that have plagued Boeing’s Starliner program. For years, the project has faced challenges such as fuel leaks, software glitches and valve failures. Despite these obstacles, Boeing and NASA remain committed to completing this historic mission, which will mark the first crewed flight of the Starliner spacecraft.

A huge challenge
When the Starliner finally lifts off, it will carry two NASA astronauts, Butch Wilmore and Suni Williams, to the International Space Station (ISS). The two U.S. Navy test pilots will oversee the spacecraft’s systems from launch to docking with the ISS, as well as conduct a series of manual piloting demonstrations. Their stay aboard the ISS will last at least eight daysafter which they will return to Earth aboard the Starliner for a parachute- and airbag-assisted landing in the southwestern United States. This Starliner flight represents a milestone in the history of American space exploration. With the Crew Dragon of SpaceXit will provide the United States with two independent spacecraft capable of carrying astronauts to the ISS. This redundancy is essential to ensure reliable access to space, reduce launch times and maintain crew safety.
