KENNEDY SPACE CENTER, Fla. – Four astronauts as part of NASA’s Crew-10 mission are now set to launch aboard a Dragon spacecraft on a SpaceX Falcon 9 rocket Friday evening from Kennedy Space Center, after the launch was called off this week due to concerns over a critical hydraulic system.
The launch was originally set for 7:48 p.m. from Kennedy Space Center’s launch pad 39A but was called off shortly after 7 p.m.
NASA and SpaceX are now targeting for no earlier than 7:03 p.m. Friday for its next attempt.

Concerns over a critical hydraulic system happened about four hours before the Falcon rocket’s planned Wednesday evening liftoff.
As the countdown clocks ticked down, engineers evaluated the hydraulics used to release one of the two arms clamping the rocket to its support structure. This structure needs to tilt back right before liftoff.
When Crew-10 arrives to the International Space Station, they will spend about a week together with Crew-9’s NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov as well as NASA astronauts Suni Williams and Butch Wilmore, who have been stuck at the space station since June.

Crew-9 had originally been a crew of four space travelers but was cut to two so that there would be room for Wilmore and Williams, who have been stranded at the space station after issues with Boeing’s Starliner capsule. The Starliner had so many problems getting to the space station that NASA ruled it too dangerous to carry anyone and it flew back empty.
Crew-10 will conduct different experiments aboard the space station, including “material flammability tests for future spacecraft designs,” according to NASA.
