What we all know—and what we don’t—about NASA’s Artemis III mission
NASA is beginning to paint in a few of the particulars of its deliberate 2027 Artemis III mission, however key questions, reminiscent of who its astronauts shall be, are but to be answered
After final month’s near-flawless Artemis II mission despatched a crew of 4 astronauts across the moon and again, NASA’s consideration has absolutely turned towards its subsequent check flight, Artemis III—the final deliberate step earlier than touchdown people on the moon.
This week NASA launched new particulars concerning the Artemis III mission that assist to sketch in a few of what the company is planning for this check flight. However key items of knowledge, such because the identities of the mission’s astronauts, stay a thriller.

Artemis III is predicted to launch in late 2027. It was initially conceived as a lunar touchdown mission, however in February NASA introduced that the company had scrapped that concept in favor of a check that shall be carried out in Earth’s orbit. Throughout that check, NASA’s Orion crew capsule (the spacecraft that housed the Artemis II astronauts on their journey across the moon) will try to dock with one or each of the 2 attainable autos that the company desires to make use of to land astronauts on the moon.
Each autos, variations of Blue Origin’s Blue Moon lander and SpaceX’s Starship, respectively, have by no means been examined in such a situation. Nonetheless, in its newest Artemis III information launch, NASA mentioned the mission’s astronauts might try not solely to dock with the lander but additionally to go away the Orion capsule and enter the automobile. That may allow the company to simulate the switch between spacecraft that shall be mandatory for a human touchdown.
“For the primary time, NASA will coordinate a launch marketing campaign involving a number of spacecraft integrating new capabilities into Artemis operations,” mentioned Jeremy Parsons, appearing assistant deputy affiliate administrator of NASA’s Moon to Mars Program Workplace, in an announcement. “We’re integrating extra companions and interrelated operations into this mission by design, which is able to assist us learn the way Orion, the crew, and floor groups all work together along with {hardware} and groups from each lander suppliers earlier than we ship astronauts to the moon’s floor and construct a moon base there.”
The Orion capsule, in keeping with new particulars, could have an up to date warmth protect design that NASA says will scale back a few of the danger concerned in reentering the environment. And the crew will spend longer on this Orion capsule than they did in Artemis II, which lasted round 10 days.
NASA has a tough plan of how the check will go: The House Launch System rocket will loft an Orion capsule, carrying an undisclosed variety of astronauts, into Earth orbit. As soon as there, the astronauts will try to dock the capsule with a lunar lander automobile and carry out a sequence of different exams designed to evaluate the company’s readiness to try a human moon touchdown. This primary define is analogous in scope to Apollo 9, a 1969 mission during which a three-astronaut crew spent 10 days testing the spacecraft’s potential to land on the moon from the consolation of low-Earth orbit.
What we don’t learn about Artemis III
There’s quite a bit NASA has but to disclose about Artemis III, together with the goal launch date, the id of the crew or the period of the mission. Beforehand, when Artemis III was conceived as a moon touchdown check, the mission was anticipated to final three to 4 weeks, in keeping with the European House Company, however that timeline doesn’t essentially apply to the brand new scope.
And NASA has not divulged whether or not there are different science experiments that the crew would possibly conduct whereas in area or if the Orion capsule could have different modifications to its insides for them to discover and check out. One other unknown is strictly what orbit the spacecraft will fly in—like Apollo 9, it will likely be in low-Earth orbit, however that would imply any altitude underneath 2,000 kilometers or so from Earth’s floor.
It’s also unclear whether or not the 2 spacecraft that Orion is meant to dock with shall be prepared for the check by late 2027—each SpaceX’s Starship and Blue Origin’s Blue Moon lunar landers have been riddled with delays. So have Axiom House’s next-gen area fits, which the Artemis III crew are supposed to check in a spacewalk exterior their capsule. All three firms have repeatedly insisted they are going to be prepared when the time comes.
NASA says it should present extra particulars on these and different questions quickly, so watch this area.
