Right before liftoff, NASA and SpaceX scrub launch of 4 crewmembers due to ground systems issue

A NASA and SpaceX rocket set to take four crewmembers to space was scrubbed right before its scheduled launch Monday morning.

The next attempt of the launch of Crew-6 is set for early Thursday morning.

The last-minute move marked the second rescheduled launch of Crew-6, originally scheduled to lift off from NASA's Kennedy Space Center in Florida on Sunday. Last week NASA and SpaceX decided to push the liftoff back by 24 hours to make time for additional checks and balances.

Then early Monday morning, NASA reported, mission teams stood down to investigate an issue with ground systems.

"I'm proud of the NASA and SpaceX teams' focus and dedication to keeping Crew-6 safe," said NASA Administrator Bill Nelson. "Human spaceflight is an inherently risky endeavor and, as always, we will fly when we are ready."

What to know about Crew-6 mission

NASA astronauts Stephen Bowen and Warren Hoburg, the United Arab Emirates' Sultan Alneyadi, and Russian cosmonaut Andrey Fedyaev were set to launch in a Crew Dragon capsule for a six-month mission to the International Space Station.

The flight is the sixth crew rotation mission with Elon Musk's space company to the station, and the seventh flight of SpaceX's Dragon Endeavor with people as part of NASA's Commercial Crew Program.

Dragon Endeavour will be launched by its Falcon 9 rocket, a two-stage rocket used to transport satellites and the spacecraft into orbit.

What are they doing up there?

Hopefully, getting a step closer to Mars.

According to NASA, crew members plan to gather new information in experiments that will bring it closer to its goal of landing on Mars, testing microgravity's effect on flames and immunity, as well as collecting microorganisms from outside the Space Station.
