This first mission will last four to six weeks, depending on when it launches, taking Orion into orbit around the moon and then back to Earth. The only piece that has flown in space before is Orion, which launched on another rocket in December 2014 to test its heat shields. Artemis I will be the first uncrewed flight test of the whole vehicle “stack”: Orion, the European Service Module, and the SLS rocket. The first mission, called Artemis I, is an uncrewed test launch that will fly as soon as November 16, with backup dates on November 19 and 25. What are the first missions of the Artemis program? Once Orion returns to Earth, the gumdrop-shaped capsule will use its heat shields to survive the blazing descent through Earth’s atmosphere and then deploy parachutes for an ocean splashdown. Starship, which SpaceX is currently testing, will then ferry the astronauts to and from the lunar surface. Orion can’t land on the moon itself, so when NASA makes its lunar landing attempt during Artemis III, it will transfer the crew from Orion to a modified version of SpaceX’s Starship spacecraft while in lunar orbit. The rocket’s upper stage will detach from the core stage once it reaches space and fire its own engines to send Orion (with the European Service Module) on its way moonward. Combined, the rocket will generate 8.8 million pounds of thrust at launch, 15 percent more than the Apollo program’s Saturn V. Artemis I, an uncrewed test flight to the moon and back, will use refurbished engines that have each flown on at least three space shuttle missions.Įach SLS rocket will also use two massive solid-fuel boosters attached on either side of the core stage. The jumbo rocket’s first stage uses four RS-25 rocket engines, originally developed for the space shuttle program. Orion’s ride to the moon is the Space Launch System, or SLS: a 322-foot-tall rocket with a core stage that burns a mix of liquid hydrogen and liquid oxygen. ![]() Each Orion capsule will fly with a European Service Module, provided by the European Space Agency, that will carry solar panels, life support systems, fuel tanks, and the main engine needed to enter lunar orbit. What spacecraft are used in the Artemis program?ĭuring their missions, the Artemis crews will live aboard Orion, a capsule designed to keep a crew of four alive and healthy in deep space for up to 21 days. 11, hitting Earth's atmosphere at tremendous speeds before ultimately splashing down softly in the Pacific Ocean off the coast of California.Please be respectful of copyright. "Distant retrograde orbit is important because it helps us to learn about how a spacecraft functions in a deep space environment." "This orbit is different than the orbit done during the Apollo program, in which the spacecraft and its crew orbited much closer to the lunar surface in a more circular fashion," Jones said during the broadcast. 1, when another engine burn will send the capsule back toward Earth. The capsule will stay in the DRO - a stable path that will take it as far as 40,000 miles (64,000 km) from the lunar surface - until Dec. 25: an engine firing designed to insert Orion into a distant retrograde orbit (DRO) around the moon. Monday's successful burn will set up another crucial maneuver on Nov. The Artemis 1 liftoff also marked the debut of the SLS, the most powerful rocket ever to launch successfully.
