NASA named four astronauts Thursday for Artemis III, a 2027 spaceflight that will spend approximately two weeks in low Earth orbit testing rendezvous and docking procedures with commercial lunar landing vehicles developed by SpaceX and Blue Origin—a mission the agency described as the most operationally complex it has undertaken since the Space Shuttle era, and the decisive technical gateway before the first crewed landing on the Moon since December 1972.
The Four-Person Crew
Commander Randy Bresnik, a retired Marine colonel who flew on space shuttle Atlantis during the STS-129 mission to the International Space Station in 2009 and later commanded the station during Expedition 53, will lead the mission. Pilot Luca Parmitano, an Italian Air Force colonel and European Space Agency astronaut who served as ISS commander during Expedition 61—becoming the first Italian to hold that post—will fly alongside him.
Mission specialists Frank Rubio and Andre Douglas complete the crew. Rubio, an Army flight surgeon, holds the record for the longest single-duration spaceflight by an American astronaut, having spent more than 371 days aboard the ISS after his Soyuz capsule was struck by a micrometeorite and required a replacement vehicle for his return to Earth. Douglas, a former Naval aviator, will be making his first spaceflight. NASA astronaut Bob Hines was named as the mission's backup crew member.
What the Mission Will Actually Do
Unlike the Artemis I and II missions that preceded it, Artemis III will not travel to the Moon. The mission profile calls for the crew to launch aboard NASA's Orion spacecraft atop the Space Launch System rocket, enter a carefully selected low Earth orbit, and then conduct a series of rendezvous and docking attempts with test versions of the human landing systems currently in development by both SpaceX—whose Starship Human Landing System is a large, high-capacity vehicle—and Blue Origin's Blue Moon lander.
Neither of those docking operations has ever been performed before in space. Previous Artemis planning assumed that docking expertise proven on the International Space Station would transfer adequately to lunar lander configurations, but the geometry, approach velocities, vehicle masses and abort options differ enough that NASA's mission architects determined a dedicated orbital demonstration was essential before committing a crew to an actual lunar descent.
"This mission will be one of the most complex that NASA has undertaken in the modern era," NASA Flight Operations Director Norm Knight said at a briefing at the Johnson Space Center in Houston. "Everything that comes after—Artemis IV, the South Pole landing, sustained lunar surface operations—depends on getting the docking mechanics right first. Artemis III is where we prove that out."
The Path to the Moon's South Pole
Artemis IV, currently targeting 2028, will be the first crewed mission to the lunar South Pole—the region where orbital observations from NASA's Lunar Reconnaissance Orbiter and data from the LCROSS impact mission have confirmed the presence of water ice in permanently shadowed craters. That ice, accessible in extractable quantities, could support a long-term human presence on the Moon by providing both drinking water and, through electrolysis, hydrogen and oxygen for propellant. The scientific and strategic significance of those resources has driven both NASA and international programs, including China's Chang'e series, to prioritize the South Pole as the primary target for crewed surface operations.
Artemis III will provide flight-proven data on how each commercial lander performs in the actual docking geometry required for the South Pole descent—data that cannot be replicated fully in ground simulation and that engineers say is essential for mission design decisions that must be finalized well before 2027 ends. "We need to know how each vehicle behaves in the real docking environment, not the modeled one," a senior Orion mission planner said Thursday, speaking on background. "The simulations are good. They're not sufficient."
The International Architecture Behind the Crew Selection
The inclusion of ESA astronaut Luca Parmitano in the pilot seat reflects the Artemis Accords framework, through which NASA has organized international participation in its lunar exploration program. More than 40 nations have signed the accords, committing to principles of transparency, interoperability and peaceful conduct in cislunar space. An ESA astronaut in a lead flying role on one of the program's most visible missions carries deliberate political weight at a moment when European space ambitions are expanding and the competition for leadership in cislunar infrastructure extends beyond any single bilateral relationship.
The crew announcement drew congratulations from ESA headquarters in Paris and from the Italian Space Agency, whose partnership with NASA on ISS missions has included multiple long-duration Italian flights. For Parmitano, whose previous missions gave him more extravehicular activity experience than any other ESA astronaut, Artemis III will mark his third spaceflight and first aboard an American spacecraft.
A Program Under Budget Pressure
The announcement arrived as NASA's Artemis program faces ongoing congressional scrutiny over costs. The Space Launch System and Orion capsule have both run significantly over their original budget estimates, and the commercial lunar landing systems have faced development delays. Thursday's crew announcement—a tangible, human face on a program that deals primarily in engineering milestones and schedule updates—was intended in part to remind Congress and the public that the flights are real, the people are ready, and the mission is within reach. Whether that message arrives with the political force NASA needs to protect its budget heading into the next appropriations cycle is a separate question from whether the crew is qualified. On the second count, at least, there is no dispute.
