NASA's SpaceX Crew-11 flight is more than just a crew rotation — it lands during a historic moment in spaceflight: the 25th anniversary of uninterrupted human habitation aboard the ISS.

The launch takes place on a milestone date, marking 20 years since the STS-114 space shuttle mission took off from Kennedy Space Center Pad 39B. The launch of Discovery on the STS-114 mission on July 26, 2005, marked the return to flight for the space shuttle after the Columbia tragedy investigation.

Endeavour is scheduled to launch atop a Falcon 9 rocket from Pad 39A — the liftoff site of most Apollo moon missions, including Apollo 11 — on July 31, kicking off SpaceX's Crew-11 mission to the International Space Station (ISS) for NASA.
