The first stage of NASA’s powerful Space Launch System (SLS) rocket for its Artemis II lunar mission has been transported from a factory in New Orleans to central Florida.
The 65-meter-high stage, manufactured by Boeing, departed the Michoud facility, NASA’s assembly center in New Orleans, Louisiana, on Tuesday. It began a journey of almost 1,500 kilometers to its final destination, the Kennedy Space Center.
At the Kennedy Space Center, this stage will be assembled with the rest of the rocket and the Orion capsule. Four crew members will travel inside the capsule on the Artemis II mission. This ten-day mission is scheduled to launch in September 2025. It will orbit the Moon but will not land.
The launch of the SLS rocket stage coincided with the 55th anniversary of the launch of Apollo 11, which took place on July 16, 1969.
“With Artemis, we set our sights on doing something big and incredibly complex that will inspire a new generation and advance our scientific endeavors,” said Catherine Koerner, associate administrator for NASA’s Exploration Systems Development Mission Directorate.
Before the launch, the SLS rocket will undergo additional equipment installation at the Kennedy Space Center, including a pair of twin booster rockets. The Orion spacecraft is already in Florida.
The SLS is the largest rocket ever built by NASA. It features four powerful RS-25 engines and two massive tanks that together hold more than 733,000 gallons of super-cold liquid propellant.
During launch, the SLS will operate for no more than 8 minutes. During this time, it will propel the Orion spacecraft out of Earth’s atmosphere and into orbit toward the Moon.
NASA’s Artemis program marks a new chapter in space exploration. It aims to lay the groundwork for a permanent human presence on the Moon.
Artemis I, an unmanned test flight of the Orion vehicle, successfully completed a round-trip flight in 2022. Following Artemis II in 2025, NASA plans to send Artemis III, the first mission to reach the lunar surface in more than 50 years, in September 2026.
