TheArtemis II moon missionis on the cusp of launching, sending four astronauts further in space than any humans before them.
The second under NASA's multibillion-dollar moon program, the mission will sendthree Americans and one Canadianon a 10-day journey around the moon and back. While no landing is in store for the astronauts, the mission serves as a vital test flight to lay the groundwork forhumans to make it back to the surfacein as little as two years.
Along the way,the Artemis II astronautswill make history, venturing about 250,000 miles inspace– further than the record-setting Apollo 13 mission – while seeing sights of the far side of the moon that no human has ever laid eyes upon.
All signs are looking positive that the mission will get off the ground as schedule as NASA prepares to soon begin loading hundreds of thousands of gallons of super-cooled liquid hydrogen and liquid oxygen into the massive rocket that will get the lunar journey underway from Florida.
Excited for the first human moon mission in more than 50 years? Here's everything to know about how you can watch the Artemis II launch.

When is the Artemis II launch? What to know about time, date
NASA is working towarda Wednesday, April 1, launch of its Artemis II mission from the Kennedy Space Center in Florida. Hitching a ride atop NASA's 322-footSpace Launch System rocket, the Orion capsule the astronauts will ride toward the moon is due to get off the ground during a two-hour launch window opening at 6:24 p.m. ET.
The weather conditions have an 80% chance of being favorable for a launch, according toNASA. But if bad weather or any other factors – such as an unforeseen issue with the spacecraft – scuttle liftoff, NASA has other backup dates available April 2-6, as well as April 30.
How to watch NASA coverage of Artemis II mission
NASA willprovide all-day coverageApril 1 of Artemis II preparations leading up to the launch of the towering Space Launch System rocket from Launch Complex 39B at the Kennedy Space Center.
Livestreams will be available throughout the day on andAmazon Prime, NASA'sYouTube channelandNASA+, the agency's free streaming service.
Future coverageon NASA+ will also be available during significant mission milestones, including lunar flyby attempts and their return to and landing back at Earth.
Schedule of Artemis II moon mission coverage
Here's a closer look at NASA's coverage schedule on April 1:

7:45 a.m. ET: Views and commentary on YouTube of operations to load liquid propellant into the SLS rocket, the most powerful rocket NASA has ever launched. The event will have its own stream closer to the start time.
12:50 p.m. ET: Coverage of the impending launch begins on NASA+.
6:24 p.m. ET: Two-hour launch window opens. Coverage on NASA+ will come to an end after the Orion capsule's solar array wings deploy in space but will continue on YouTube.
Two-and-a-half hours after launch: NASA will host a news conference after the SLS rocket's upper stage performs a burn to send the Orion capsule and its crew to high-Earth orbit.
Real-time mission coverage will continue on YouTube throughout its duration, including live conversations with the crew. The agency also will provide a separate live stream of views from the Orion spacecraft as bandwidth allows.
Updates on these events will be available on NASA'sArtemis blog.
Artemis rocket launch to take 4 astronauts around the moon
Under its Artemis campaign, NASA is aiming to return astronauts to the surface of the moon for the first time since theApollo missions came to an endin 1972.
But this time, astronauts won't simply plant the stars and stripes before heading back to Earth. NASA is looking to establish a permanent foothold on the lunar south pole, using a series ofcrewed and uncrewed missionsin the years ahead tobuild a moon base.
From there, the first humans could be venturing to Mars.
As a 10-day moon-circling mission, Artemis II primarily serves as a test flight, with the four-person crew testing systems and hardware ahead of a future landing.
In 2027, another crew of astronauts is due to ride Orion to Earth orbit to test docking capabilities with one or both of thecommercial lunar landersbeing developed byElon Musk's SpaceX and Jeff Bezos'Blue Origin. A lunar landing would then come in2028 under Artemis IV.
