Watch NASA’s Artemis 1 SLS mega rocket launch to the moon for free with these live webcasts

NASA’s massive Artemis 1 rocket is counting down to a target in August. 29 will go to the moon, and when it does, you’ll be able to watch the historic mission live for free.

The space agency will host the Artemis 1 webcast series this week and next, ahead of the uncrewed launch of NASA’s first Space Launch System megarocket from Launch Pad 39B at Kennedy Space Center in Florida. Briefings will begin on Monday, 8 August. 22, and runs until launch day and includes special guests such as actors Chris Evans, Jack Black and Keke Palmer. You can already see live views of the Artemis 1 lunar rocket at its site live.

The last time such a powerful rocket thundered over the KSC site was back in 1973, when the Saturn V moon rocket launched Skylab into orbit, marking the end of the Apollo era, so this month’s event should be quite the show.

According to NASA (will open in a new tab), the space agency will provide comprehensive pre-launch, launch and post-launch coverage for Artemis I when it’s time to light the candle. This landmark uncrewed dress rehearsal around the Moon will clear the way for crewed flight tests on the Moon with Artemis 2 in 2024 and an actual lunar landing by 2025 as part of Artemis 3.

Those lucky enough to join the Artemis 1 show in Florida will experience the shock and awe of the 8.8 million pounds of gravity-fighting thrust that launches the sleek SLS rocket and Orion space capsule into the sky. For the rest of us, NASA just released a schedule of free live streams so we can watch the mission from the comfort of our own homes.

Live coverage of the events will be streamed on thanks to NASA TV, NASA’s mobile app. (will open in a new tab)and official website of the agency (will open in a new tab), with pre-launch activities on Monday, Aug. 22. For those greedy to madness, the launch countdown. (will open in a new tab)starts on Saturday, Aug. 27 at 10:23 am ET.

Sure, it might not give you the same epic experience as taking off the Earth, but it’s the next best thing and you don’t have to worry about heat, parking issues, or huge crowds.

Monday, Aug. September 29 is the first attempt to launch NASA’s Artemis 1 lunar mission and it will be a LONG day.

NASA webcasts begin at 1200 ET (0400 GMT) with a live webcast of fueling operations, which NASA refers to as space launch system fueling. The main stage of an SLS rocket can hold about 730,000 gallons of ultra-cold liquid oxygen and liquid hydrogen, so loading this propellant will take several hours.

Monday, Aug. 29:6:30 ET – Artemis 1 launch full coverage

NASA’s full webcast of the Artemis 1 launch will begin in August. 29 at 6:30 AM EST (10:30 GMT). This part of the agency’s webcast will be in English.

“Launch coverage will continue through translunar injection and spacecraft separation, guiding Orion on its path to the Moon,” NASA’s description reads.

Monday, Aug. 29:7:30 ET – Spanish Broadcast Artemis 1

At 7:30 AM EST (1130 GMT), a NASA webcast in Spanish will begin chronicling the Artemis 1 mission.

The webcast will run through the launch and the first 15 minutes of the mission after launch. Once launched, you can receive updates in Spanish about Artemis 1 through NASA en español social media channels.

Saturday, Aug. 29:8:33 EDT – Artemis 1 launch

This is the moment of truth for NASA’s Artemis 1 mission: the first launch window of the Space Launch System rocket.

In fact, NASA has a two-hour window in which to attempt to launch an SLS booster, so launch can occur anytime between 8:33 AM EST and 10:33 AM EST (12:33- 14:33 GMT), weather and technical systems permitting.

Saturday, Aug. 29:12 ET – Post-launch press conference for Artemis 1.

After launch, NASA will hold a post-launch press conference scheduled no earlier than 1 hour after the end of the launch broadcast. NASA is currently looking at a start time for this briefing at 12 noon EST (1600 GMT), but this may change during the day.

  • Bill Nelson, NASA Administrator
  • Mike Sarafin, Artemis Mission Leader, NASA Headquarters
  • Mike Bolger, Ground Systems Intelligence Program Manager, Kennedy
  • Howard Hu, Orion Program Manager, Johnson
  • John Honeycutt, Space Launch System Program Manager, Marshall

If all goes well with the launch, NASA will host a webcast at 1600 ET (2000 GMT) to highlight the first trajectory maneuver to send Artemis 1 Orion out of Earth orbit and head to the Moon.

The timing of this illumination may vary depending on the launch time of the Artemis 1 mission.

Saturday, Aug. 29:5:30 EDT – Views of Earth from Orion

The last major launch day event for Artemis 1 is currently scheduled for 5:30 pm EDT (9:30 pm GMT), when the Orion spacecraft is expected to show Earth from space for the first time.

As with the outbound maneuver, the timing of this broadcast is subject to change depending on the exact launch time and the condition of the Orion spacecraft.

For a full rundown of all the talk and events surrounding the exciting Artemis 1 flight, check out NASA’s detailed coverage schedule.

Whether you pick a nice spot to view Artemis 1 in person or take it all in via NASA live streams, this is destined to be the fireworks show of the summer!
