NASA is about to launch the Artemis I mission to the Moon, and you can watch the launch live.
And in late 2025, Artemis III will carry astronauts to a landing site near the Moon’s south pole, where two members of the crew will become the first humans to set foot on another world since 1972. Artemis I is an uncrewed (except for the mannequins) test of the Space Launch System rocket and the Orion crew capsule. It will also help design more realistic, more useful training simulations for the crews of Artemis II and Artemis III. The recovery vessel knows where to be because Orion will make a much more precise landing than the Apollo capsules were able to do. That first dip into the atmosphere helps spread out the heat and G-forces of re-entry, which will help make the process safer and smoother for future missions' crews. Here’s everything you need to know about the Artemis I mission and how to watch the historic launch. Five days later, on September 3, Orion will swoop past the Moon on its closest approach, just 96 kilometers above the rocky lunar surface. And throughout the mission, hardcore space fans can tune into a livestream of one of NASA’s test mannequins, nicknamed Commander Moonikin Campos, who is testing a new spacesuit for NASA: the Orion Crew Survival System flight suit. Launching on September 2 or September 5, however, Orion can cruise in the sun all the way to the Moon. After a series of delays, NASA’s Artemis I mission is on the brink of launch. But if you aren’t up for an all-nighter and just want to catch the launch itself, tune in bright and early on Monday morning. The show begins at midnight Eastern Time, when crews at Kennedy Space Center will begin fueling the rocket with supercooled liquid propellant and continues through the night with the early phases of countdown.
NASA's Artemis 1 mission will launch on the first Space Launch System rocket and its Orion spacecraft on Monday, Aug. 29.

If overcast conditions are expected near viewing sites, that could easily obscure most of the launch process even though it will still be audible. The noise will just bounce back and forth and continue to propagate with the wind." Once SLS clears treelines and buildings, most folks in town to witness the launch should have spectacular views. But those viewing from popular sites at or near KSC will likely experience sounds north of 100 decibels – equivalent to a jackhammer. Though those factors will impact the experience, there's no other way to explain it for locals: SLS will not be shy. That’s not to say out-of-towners won’t be able too see it since some daytime launches are seen as far away as a 150-mile radius around KSC, including areas like Tampa, Orlando, and Jacksonville. SLS will produce a fair amount of low-frequency rumble thanks to its massive side-mounted solid rocket boosters. [Space is important to us and that’s why we're working to bring you top coverage of the industry and Florida launches. "But the decibel level is an extremely strong function of where you are."

The crew of Artemis 3 hasn’t been publicly revealed either, but NASA have promised to land the first female astronaut and first astronaut of colour on the Moon. The Artemis 2 crew will consist of three NASA astronauts and a colleague from the Canadian Space Agency. It will travel back towards the Moon's surface to get another kick in the direction of the Earth. Currently slated for 2027, it would act as a staging post for future trips to the lunar surface. It provides the propulsion to fling Orion out of Earth orbit and on a rendezvous path with the Moon. Commander Moonikn Campos is a mannequin being used to measure the effects of accelerations and vibrations on future human astronauts. "Our hope is that including Kate and Kyle in this space mission will excite students about the possibilities of STEAM careers and engage them in their own learning journey," said Esben Stærk, president of LEGO Education. This time the space agency plans to maintain a permanent presence on the Moon. The final part of Orion is no less important. SLS will accelerate the Orion capsule to speeds of nearly 40,000 km/h and generate 15 per cent more thrust than the famous Saturn V rocket that sent the Apollo astronauts to the Moon. NASA is ready to kick-start an exciting new era of space exploration by launching the first mission in its Artemis programme.

"There are some concerns, but for now we have a fair opportunity to launch." "Sometimes going back as far as four hours to producing lightning then could potentially be a no-go situation." A launch could also be scrubbed when thunderstorms are in the vicinity. We forecast seas and waves all the way from New Orleans to the Cape." Meteorologists have been working for years for a near-perfect forecast to allow for this mission's 40,000-mile trip beyond the moon and back to Earth. "Roughly 16% of every launch attempt we have at Cape Canaveral gets scrubbed due to weather," said Burger, who has 23 years of forecast experience.

To return, Orion will use the moon's gravity to assist it in setting a trajectory back into Earth's orbit. Artemis I will travel about 1.3 million miles over the course of 42 days, spanning several phases. The return to Earth will be especially crucial, as Orion will re-enter the Earth's atmosphere at about 25,000 miles per hour. The uncrewed launch marks the debut of the most powerful rocket ever assembled and kicks off NASA's long-awaited return to the moon's surface. According to NASA, the Artemis program supports about 70,000 jobs around the country. For Artemis I, there will be three mannequins inside the Orion capsule to collect data via sensors about what astronauts will experience on the trip to-and-from the moon. NASA's Artemis plan relies on the success of another monster rocket as well: SpaceX's Starship. NASA's Orion capsule can carry four astronauts on missions up to 21 days long without docking with another spacecraft. But the rocket is only just now debuting, having cost more than $20 billion to develop, and its NASA's Inspector General, its internal auditor, earlier this year said Artemis is not the "sustainable" moon program that the agency's officials say it is.
