[UPDATE: Weather concerns have prompted the mission team to pause the countdown clock. It’s now targeting 5:23 a.m. ET for launch, nearly two hours later than originally planned. However, a final decision has yet to be made.]

SpaceX is targeting Tuesday, September 10, for the launch of the all-civilian Polaris Dawn mission that will take a Crew Dragon spacecraft to its highest orbit and also feature the first commercial spacewalk.

The Elon Musk-led company will live stream the launch from the Kennedy Space Center in Florida. Read on below for full details on how to watch.

The mission will be led by billionaire businessman Jared Isaacman, the CEO of payment processing firm Shift4 and an accomplished pilot. Isaacman has traveled to space once before, on the SpaceX-operated Inspiration4 mission in 2021. The businessman funded that mission and is also funding the Polaris Dawn endeavor.

Flying alongside Isaacman will be three other nonprofessional astronauts, namely Scott Poteet, a retired U.S. Air Force lieutenant colonel; Sarah Gillis, a lead space operations engineer at SpaceX who oversees the company’s astronaut training program; and Anna Menon, a lead space operations engineer at SpaceX who is responsible for managing the development of crew operations and who also serves in mission control.

The crew are now inside the Crew Dragon with liftoff targeted for 5:23 a.m. ET.

During the five-day mission, the Crew Dragon spacecraft will reach its highest-ever orbit, about 435 miles (700 kilometers) above Earth and some 185 miles (298 kilometers) above the International Space Station, which is where the spacecraft usually heads to as part of NASA’s crew rotation missions.

During the two-hour spacewalk, Isaacman and Gillis will test a newly designed spacesuit to confirm that it moves and functions as expected in the vacuum of space.

“The development of this suit and the execution of the [spacewalk] will be important steps toward a scalable design for spacesuits on future long-duration missions,” SpaceX said on the Polaris Dawn website.

The crew will also carry out a number of other science- and technology-based tests while in orbit.

How to watch

SpaceX is targeting 5:23 a.m. ET (2:23 a.m. PT) on Tuesday, September 10, for the launch of the Polaris Dawn mission from the Kennedy Space Center in Florida. The launch window will last for four hours. A live stream showing final preparations will begin just after midnight ET.

You can watch the Falcon 9 rocket carry the crew to space via SpaceX’s feed on X (formerly Twitter).

Cameras will capture the early stages of the mission from the ground, from the exterior of the rocket, and also from inside the Crew Dragon capsule.

If there are any changes to the schedule, we’ll be sure to update here just as soon as we can. For the very latest information, check Polaris Dawn’s X account.

NASA built the Roman Space Telescope to study dark matter, but it can also help protect Earth from killer asteroids
The Nancy Grace Roman Space Telescope wasn't built to hunt asteroids, but it turns out to be great at it.
Nancy Grace Roman space telescope.

NASA is about to launch a telescope built to unlock some of the universe's biggest mysteries, and it turns out that same design could help protect Earth along the way.

The Nancy Grace Roman Space Telescope is set to launch from Kennedy Space Center on August 30, 2026, with a primary mission focused on studying dark matter and dark energy - the invisible forces shaping galaxies and cosmic expansion. Researchers now say its unique design also makes it unexpectedly effective at spotting dangerous asteroids headed our way (via MIT Technology Review).

Space is becoming Bezos and Musk’s next data center site, and we have every reason to worry
The AI boom is coming for the night sky
How Vast's space station will look in orbit.

AI data centers already consume vast amounts of electricity and water on Earth, so Silicon Valley has begun looking somewhere considerably more spacious... literally.

Elon Musk's SpaceX and Jeff Bezos' Blue Origin, along with several other companies, have proposed enormous constellations of satellites designed to operate as orbital data centers. However, environmental groups and former space officials are now warning that putting them into orbit at the proposed scale could have severe consequences for Earth's atmosphere and the night sky.

The first possible exomoon is here, and it makes our Moon look hilariously tiny
Scientists may have found the first exomoon, except this one is the size of Jupiter
This artist’s concept depicts a potential volcanic moon between the exoplanet WASP-49 b, left, and its parent star. New evidence indicating that a massive sodium cloud observed near WASP-49 b is produced by neither the planet nor the star has prompted researchers to ask if its origin could be an exomoon.

We have already discovered more than 6,000 planets outside of our immediate neighborhood. Yet, finding a moon orbiting one of those distant worlds has proved considerably harder. Astronomers may finally have something close to the real deal, but this particular object stretches the word “moon” almost beyond recognition.

Using the European Southern Observatory’s Very Large Telescope in Chile, researchers detected strong evidence for a moon-like object in the CD-35 2722 system. Further observations are still necessary to confirm the discovery, but it could become the first confidently detected natural satellite outside our solar system. There is still one tiny complication though. This moon is apparently massive.
