SpaceX Dragon capsule launch to International Space Station delayed until July 11

In another blow to NASA’s cargo resupply mission, the agency announced Monday that it would be launched no earlier than July 11. The mission, dubbed CRS-25, involves sending an uncrewed Crew Dragon capsule to the International Space Station (ISS) atop SpaceX’s Falcon 9 rocket. from Kennedy Space Center in Florida. This is the second time that NASA has postponed the first mission between June 10 and June 28.

Hardware issues persist with Dragon Capsule

“NASA and SpaceX officials met today to discuss initial findings from additional inspection and testing of the Dragon spacecraft after measuring elevated vapor readings of mono-methyl hydrazine (MMH) in an isolated area of ​​the Dragon propulsion system” , NASA said in one. Statement.

The reason for the delay in CRS-25 from 10 June was an increase in the vapor level of hydrazine—the propellant used by Dragon’s Draco thrusters. “after unloading the propellant from that area” [of Dragon’s propulsion system]SpaceX was able to narrow down the source of the issue to the Draco thruster valve inlet joint”, NASA adds.

“The team will now remove specific hardware to replace it prior to flight. NASA and SpaceX are now targeting to launch the CRS-25 cargo response mission to the International Space Station before July 11,” the agency said. Notably, all launch-related events will be broadcast live on NASA’s official website, its official application, and its YouTube channel.

The upcoming launch will mark SpaceX’s 25th resupply mission to the ISS, in addition to the five crewed launches the company has conducted for NASA since 2020. The Dragon capsule will liftoff with a number of new experiments and stuff for the Expedition 67 crew that is already doing a lot of science. Mission in zero-gravity.

Following Dragon’s arrival at the ISS, the list of experiments will include manufacturing concrete for bricking on the Moon, developing a system to reverse the aging process, and mapping the dust that rises to Earth’s atmosphere.
