SpaceX's rocket test-fired the rocket for its next astronaut launch early Friday (Feb. 24) in a dress rehearsal to send a new crew into space next week.
A Falcon 9 rocket performed a static fire for SpaceX on Friday (Feb. 24) with its Crew Dragon Endeavour capsule on top. The dress rehearsal was one of the last milestones before SpaceX launches four astronauts on the Crew-6 mission to the International Space Station on Monday (Feb. 27). Liftoff is scheduled for 1:45 a.m. EST (0645 GMT) and you'll be able to watch it live on Space.com.
"While standing on the launch pad at Kennedy Space Center’s Launch Complex 39A in Florida, the rocket's nine Merlin first-stage engines roared to life for seven seconds, completing the routine but critical integrated static fire test," NASA officials wrote of the successful test in a blog post.
SpaceX's Crew-6 mission will launch NASA astronauts Stephen Bowen and Warren Hoburg to the International Space Station alongside Russian cosmonaut Andrey Fedyaev of Roscosmos and United Arab Emirates astronaut Sultan Al-Neyadi.
Crew-6 will be SpaceX's seventh crewed mission for NASA (including the Demo-2 demonstration flight) under the agency's commercial crew program, and the ninth time it sent humans to space.
MS-23 should dock with the space station on Saturday, providing a ride home for NASA astronaut Frank Rubio and cosmonauts Sergey Prokopyev and Dmitri Petelin; their nominal return home has been postponed six months to September to make room for another crew to relieve them.
Four other astronauts on the ISS have another SpaceX Crew Dragon at hand; in case of emergency, Rubio could squeeze in there while Prokopyev and Petelin would be able to ride the damaged MS-22 back home.
SpaceX is considering a launch of another Falcon 9 rocket with Starlink internet satellites Sunday, Feb. 26 1:12 p.m. EST (1812 GMT), but that may push to make priority for Crew-6.
