NASA urgently postpones launch of Crew Dragon with astronauts to ISS 150 seconds before liftoff, and SpaceX may set historic milestone

The Crew Dragon Endeavour spacecraft has not set off for the International Space Station ISS), despite plans. The National Aeronautics and Space Administration (NASA) has postponed the launch.

Here's What We Know

SpaceX's spacecraft was sent to the launch pad as early as last week. The Crew-6 mission was scheduled to launch at 02:45 (EDT) or 23:45 (PDT). Crew Dragon was supposed to carry a group of astronauts to the ISS. NASA reported a problem with the ground support system and halted the mission 150 seconds before liftoff.

The Falcon 9 rocket is used to send the spacecraft into space. It uses TEA-TEB fluid, which is responsible for the ignition. Specialists noticed a problem with the fluid, but could not fix it in time.

Astronauts Woody Hoburg and Stephen Bowen from the USA, Sultan Al Neyadi from the UAE and Andrey Fedyaev from Russia are scheduled to travel to the ISS on the sixth mission of the Commercial Crew programme. The second attempt is scheduled for tomorrow, February 28. The mission will launch at 02:00 (EDT) or 23:00 (PDT). If that happens, SpaceX could have three launches within 12 hours. The record for that number of launches is 34 hours.
