NASA is about to perform the first-ever launch of its next-generation rocket and spacecraft in a highly anticipated lunar mission, and you can watch the entire event online.

Following a failed launch attempt on Monday, the Artemis I mission is now scheduled to launch from the Kennedy Space Center in Florida on Saturday, September 3.

The flight will usher in a new era of space exploration as NASA eyes lengthy crewed stays on the moon and the first astronaut voyage to Mars.

Saturday’s launch involves the 98-meter-tall Space Launch System (SLS), the most powerful rocket NASA has ever built, and the Orion spacecraft, the space agency’s next-generation crew capsule.

The SLS rocket will send the crew-less Orion vehicle on a 42-day test flight that will see it perform a fly-by of the moon, taking the capsule within 62 miles of the lunar surface. It will then return to Earth for a splashdown off the coast of California.

A successful Artemis I mission will pave the way for Artemis II, which will take the same route, only this time, with astronauts on board. Then, as early as 2025, Artemis III will endeavor to put the first woman and first person of color on the lunar surface in what will be the first astronaut lunar landing since the final Apollo mission in 1972.

How to watch

If you’re not lucky enough to be able to head to the Space Coast to watch the launch in person, then simply find a comfy seat at home and watch it from there instead.

The launch of Artemis I from the Kennedy Space Center in Florida is currently scheduled for 2:17 p.m. ET on Saturday, September 3. Coverage of the build-up, including the rocket’s fueling process, will begin at 12:15 p.m. ET.

You can watch a livestream of the event by using the video player embedded at the top of this page or by heading to NASA Live TV, which will carry the same feed.

Besides what promises to be a spectacular rocket launch, the livestream will also cover the rocket’s core stage separation, Orion’s solar wing deployment, and various burns and maneuvers that will take place in the 90 minutes or so after the SLS lifts off. After that, this handy online tool will let you track Orion’s progress during its six-week journey to the moon and back.

If, for whatever reason, NASA is unable to launch on Saturday, another opportunity will be on September 5.

We’ll be sure to update this article with any changes to the schedule just as soon as we hear about them.

NASA has released a detailed animation (above) showing how the Artemis II mission will look from launch to splashdown.

The Artemis II mission is currently scheduled to launch from Florida's Space Coast in early 2026 and will fly four astronauts around the moon before returning to Earth. The highly anticipated mission will last about 10 days and will be the first crewed test flight of the Space Launch System (SLS) rocket, and the Orion spacecraft.

This week will feature a historic event as Firefly Aerospace launches its first mission to the moon. The Blue Ghost mission aims to put a lander on the moon carrying NASA science experiments, as part of NASA's efforts to get private companies involved in lunar exploration. If the landing succeeds, it will be just the second soft lunar landing by a private company, following the Intuitive Machines Odyssey lander last year.

Firefly Aerospace's Blue Ghost mission will launch late at night on Tuesday, January 14, or Wednesday, January 15. Using a SpaceX Falcon 9 rocket, the Blue Ghost will launch from Launch Complex 39A at Kennedy Space Center in Florida. The launch will be liveistreamed by NASA, and you can watch it either on YouTube or by using the video embedded below:
