How to watch NASA’s moon rocket head to launchpad tonight

By
Artemis I Wet Dress Rehearsal

Fans of slow TV are in for a treat tonight when NASA begins rolling its next-generation moon rocket to the launchpad for testing ahead of a lunar mission in the coming months.

A giant low-slung transporter will carry the 332-feet (98.1-meter) Space Launch System (SLS) rocket and Orion spacecraft along the four-mile route from the Kennedy Space Center’s Vehicle Assembly Building to the launchpad. Traveling no faster than 1 mph, the process is expected to take between 8 and 12 hours.

The new lunar rocket and spacecraft were first rolled to the launchpad in March. But the subsequent wet dress rehearsal, which involved filling the rocket’s tanks with fuel and performing a mock countdown, surfaced a number of technical issues that forced engineers to return the rocket to the Vehicle Assembly Building for repairs.

Those issues have now been fixed, paving the way for the rocket’s return to the launchpad. A second attempt at the wet dress rehearsal is expected to begin in about two weeks’ time.

How to watch

NASA is livestreaming the entirety of the rocket’s journey to the launchpad. The SLS and Orion spacecraft are scheduled to emerge from the Vehicle Assembly Building at 12:01 a.m. ET on Monday, June 6 (9:01 p.m. PT on Sunday).

You can watch the livestream by using the video player embedded at the top of this page or by heading to NASA’s website, which will show the same footage. If you’d prefer to see the rocket in daylight, then be sure to fire up the player when you wake up on Monday morning, at which point the rocket should be close to reaching the launchpad.

Assuming the wet dress rehearsal goes to plan this time around, NASA will send the SLS rocket and Orion spacecraft on an uncrewed flyby of the moon in the Artemis I mission in what will be the system’s first full flight test. No date has been set for the mission, but the hope is that it will get underway in the next few months.

Following that, NASA will launch Artemis II, which will send the rocket and spacecraft on the same path but this time with a crew on board.

If that mission proceeds without any major hitches, Artemis III will use SLS and Orion to put the first woman and first person of color on the lunar surface in the first crewed moon landing since the last Apollo flight in 1972. Artemis III is currently scheduled to take place no earlier than 2025.

Another piece of NASA’s mega moon rocket ships out
Crews moved the cone-shaped launch vehicle stage adapter out of NASA Marshall’s Building 4708 to the agency’s Pegasus barge on August 21. The barge will ferry the adapter first to NASA’s Michoud Assembly Facility, where it will pick up additional SLS hardware for future Artemis missions, and then travel to NASA Kennedy. In Florida, teams with NASA’s Exploration Ground Systems will prepare the adapter for stacking and launch.

Even while NASA is struggling with Boeing's new crewed Starliner spacecraft, it is continuing work on another key piece of space infrastructure: its Space Launch System, or SLS rocket that is designed to carry astronauts to the moon and beyond. Parts of the new rocket are arriving at the Kennedy Space Center in Florida, and now another key piece is on its ways: the launch vehicle stage adapter.

Standing at 322 feet tall when fully stacked, the SLS is NASA's most powerful rocket to date and has already been on a test flight around the moon as part of the Artemis I mission in 2022. Now, NASA is preparing for its first crewed flight using the rocket, which will be the Artemis II mission scheduled for September 2025. Unlike NASA's current woes with the Starliner spacecraft, which ferries astronauts between Earth and the International Space Station, the Artemis II mission will use a different spacecraft called the Orion.

NASA's epic Space Launch System rocket, standing 322 feet tall when fully stacked, has recently been on an similarly epic journey -- traveling from New Orleans to Florida via barge. The rocket began its journey more than two weeks ago, and having covered more than 900 miles has now arrived safe at the Kennedy Space Center.

NASA’s powerful Space Launch System (SLS) rocket is set to blast four astronauts to space next year on the epic Artemis II mission that will come within about 80 miles of the lunar surface.

In preparation for the mission, the rocket’s 213-foot-tall (65 meters) core stage has just embarked on a rather more leisurely journey -- on a barge heading for the Kennedy Space Center in Florida.
