After the historic Artemis 2 mission around the Moon, NASA is turning its focus to Artemis 3. The agency recently shared some preliminary flight plans, and they offer a fresh perspective on what to expect.
Artemis 3 is set to launch no earlier than late 2027. This mission will test how well NASA’s Orion spacecraft can rendezvous and dock with lunar landers from SpaceX and Blue Origin. This is a key step towards the Artemis 4 mission, which will include a crewed Moon landing. Since February, engineers have been working on the mission profile, aiming to streamline operations and reduce risks in the Artemis program.
One surprising change in the plan involves NASA’s Space Launch System (SLS) rocket. For this mission, the SLS will carry Orion without its upper stage, known as the Interim Cryogenic Propulsion Stage (ICPS). Typically, this upper stage helps Orion reach high-Earth orbit, but since Artemis 3 will remain in low-Earth orbit, it can launch successfully without it. Instead of the ICPS, the mission will use a “spacer” that mimics its size and weight.
Additionally, there’s an interesting twist regarding the landers. SpaceX’s Starship Human Landing System and Blue Origin’s Blue Moon Mark 2 will also launch separately. The plan hinges on their readiness for a crewed test flight. If both landers are ready, Orion will dock with each for astronaut testing. If one isn’t ready, astronauts may only be able to test one lander. NASA’s update hinted at a possible “Plan C,” which could involve astronauts entering only one lander’s prototype, indicating that neither may be fully operational by then.
Blue Origin is actively preparing for its lander demonstrations, including tests with the existing Mk1 cargo lander. Meanwhile, SpaceX has reached significant milestones in developing its landers. However, the biggest challenge lies in getting the newest version of Starship off the ground.
The Artemis 3 crew will spend more time aboard Orion than the Artemis 2 astronauts did. During Artemis 2, the crew spent 10 days in Orion, but the upcoming mission will extend this time frame. This extended duration will help further evaluate life support systems, and for the first time, the performance of the docking system will be demonstrated.
Why the longer mission duration? It could be due to the separate launch schedules of the landers or more extensive testing required aboard Orion.
As Artemis 3 approaches, NASA will provide more details. Upcoming missions will offer insight into the readiness of the landers, including Starship’s first launch and Blue Origin’s Moon landing demonstration later this year. It’s an exciting time as we await the next chapter in lunar exploration.
