NASA Preps Artemis 3 Rocket for 2027 Moon Lander Test

The massive core stage of NASA's Artemis 3 rocket now towers inside Florida's Vehicle Assembly Building, a powerful symbol of America's push to return astronauts to the moon.

Technicians at Kennedy Space Center just lifted the 212-foot section into position in High Bay 2. Once engineers attach four RS-25 engines, the stage will move to an even taller bay for final assembly with the Orion spacecraft.

The milestone comes just one month after Artemis 2 astronauts splashed down in the Pacific Ocean following their successful lunar flyby. That April mission carried NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian astronaut Jeremy Hansen on Orion's first crewed flight.

Now that Orion has proven itself with people aboard, Artemis 3 will tackle a different challenge. Instead of flying to the moon, this mission will stay in Earth orbit to test the spacecraft that will actually land on the lunar surface.

NASA changed plans after delays in developing two moon landers. SpaceX's Starship and Blue Origin's Blue Moon both need more testing before they can safely carry astronauts to the surface.

Artemis 3 astronauts will launch aboard Orion and meet one or both landers in orbit. They'll practice the delicate docking maneuvers that future moon missions will depend on, giving engineers real-world data before committing to an actual landing.

Why This Inspires

This shift shows NASA's commitment to safety over speed. Rather than rush to plant flags, the agency is taking time to get it right.

The fully assembled SLS rocket will stand 322 feet tall and weigh 5.75 million pounds when fueled. If testing goes well and at least one lander passes its trials, NASA plans to launch Artemis 4 in 2028 as the program's first crewed moon landing since 1972.

The space agency's ultimate goal reaches beyond quick visits. NASA aims to fly regular astronaut missions starting in 2028 and build a permanent base at the lunar south pole by the early 2030s.

Each vertical rocket stage brings that future one step closer.
