SpaceX has delayed the launch of the highly anticipated Polaris Dawn mission by 24 hours while engineers look into a ground-based helium leak.

The Elon Musk-led spaceflight company had been hoping to launch the all-civilian flight at 3:38 a.m. ET today (August 27), but it’s now targeting the same time on Wednesday.

SpaceX said in an announcement on social media on Monday — posted about seven hours before the original targeted launch time — that teams were “taking a closer look” at the issue while adding that the Falcon 9 rocket and Crew Dragon spacecraft, as well as the four crew members, remained in good shape.

“Teams are taking a closer look at a ground-side helium leak on the Quick Disconnect umbilical,” SpaceX said in the post on X (formerly Twitter). “Falcon and Dragon remain healthy and the crew continues to be ready for their multi-day mission to low-Earth orbit. Next launch opportunity is no earlier than Wednesday, August 28.”

Much excitement surrounds the five-day Polaris Dawn mission as it will see SpaceX’s Crew Dragon vehicle fly about 435 miles (700 km) from Earth, further than it’s ever flown before. This also means that the capsule will be taking humans to the furthest point from Earth since the final Apollo mission in 1972.

The mission will also see the first commercial spacewalk involving non-professional astronauts. During their time outside the spacecraft, Jared Isaacman and Sarah Gillis will test out brand new spacesuits that could also be used for future missions to the moon.

There’s clearly a lot riding on the mission, and so fingers are crossed that SpaceX engineers can resolve the current issue and launch on Wednesday morning.

How to watch SpaceX’s fifth Starship test flight on Sunday

SpaceX is getting ready to launch its mighty Starship on its fifth test flight, scheduled for Sunday, October 13. With a mostly-successful fourth test flight behind it, the Starship has already been into orbit and returned to Earth mostly intact. This time, SpaceX will be hoping to catch its Super Heavy booster as well as taking the upper stage Starship into orbit.

The exact date of this fifth test flight has been delayed due to issues with licensing from the Federal Aviation Administration (FAA), but SpaceX has now confirmed it is targeting 8 a.m. ET (5 a.m. PT) Sunday for its test.

SpaceX could launch Starship on 5th test flight much earlier than expected
The world's most powerful rocket on the launchpad.

There’s growing expectation that SpaceX could launch the mighty Starship rocket as early as Sunday, October 13.

SpaceX was informed by the Federal Aviation Administration (FAA) last month that it was unlikely to receive a launch permit until late November as the regulator needed time to complete work on its flight launch assessment.

SpaceX has released some remarkable footage (below) showing a Crew Dragon spacecraft zipping through space, with the Pacific Ocean several hundred miles below.

Aboard the Crew Dragon were NASA astronaut Nick Hague and Russian cosmonaut Aleksandr Gorbunov as they made their way to the International Space Station (ISS) in SpaceX's Crew-9 mission.
