NASA’s plan to return astronauts to the lunar surface in 2027 hinges on a spacecraft that remains stubbornly elusive in its reliability: SpaceX’s Starship. Towering at 403 feet, the largest rocket ever built was originally conceived as a Mars vehicle but has since been repurposed as a central element of NASA’s Artemis program. On its ninth launch, Starship reached space, only to tumble uncontrollably during reentry and break apart. This follows two prior flights that ended in explosions over the Caribbean.
The repeated failures have intensified scrutiny of the Artemis timeline, already considered aggressive by many in the aerospace community. Yet industry veterans remain measured in their response. Starship’s engineering complexity is unprecedented, and each test flight yields valuable data despite dramatic setbacks. Elon Musk underscored this point on X after the latest mission: “Starship made it to the scheduled ship engine cutoff, so big improvement over last flight! Also, no significant loss of heat shield tiles during ascent. Leaks caused loss of main tank pressure during the coast and re-entry phase. Lot of good data to review.”
NASA spokesperson Cheryl Warner echoed that sentiment, noting the human landing system will be a different variant of Starship than the developmental model now flying. “We have confidence SpaceX will fully investigate every aspect of their test flight and address any issues,” she said. Phil Larson, a former space adviser to President Barack Obama, framed the iterative process as part of a modern space race: “This is to be expected and actually fun to watch. This is our version of the space race in the ’60s, updated with new technology, better rockets, reusable systems.”
Still, the stakes are high. Artemis III, slated for mid-2027, aims to land astronauts near the moon’s south pole. The architecture involves NASA’s Space Launch System sending four astronauts in the Orion capsule to lunar orbit, where a modified Starship—the Human Landing System—will ferry two of them to the surface and back. The lander’s height, over 160 feet, necessitates an elevator for crew descent. Before any crewed landing, SpaceX must demonstrate an uncrewed lunar touchdown and develop orbital refueling capabilities using multiple Starship tanker launches.
Pam Melroy, former astronaut and deputy NASA administrator, emphasized the urgency: “If NASA wants to fly Artemis 3 in 2027 like it’s on the books, SpaceX should be doing its uncrewed landing demo on the moon no later than mid-to-late next year with Starship.” She added that proving a fuel depot system is essential for the mission profile.
The Artemis program’s origins trace back to 2019, when NASA targeted a 2024 landing—a date that slipped after Artemis I’s uncrewed lunar flyby in 2022. Artemis II, a crewed lunar orbit mission, is planned for next year. The program has already consumed around $100 billion, according to NASA’s inspector general, and its multi-element design has drawn criticism. Robert Zubrin, president of the Mars Society, described it bluntly: “The current architecture of Artemis does not make sense. It’s five separate elements which have each been funded for different reasons.”
SpaceX’s track record with Falcon 9 and Dragon has made it the dominant launch provider globally, ferrying astronauts to the International Space Station with routine reliability. But Starship’s scale and reusability goals push into territory never before attempted. Lori Garver, NASA’s deputy administrator during the Obama administration, observed, “Starship is an order of magnitude more challenging than Falcon 9 was. Some of this is new ground. The size of the vehicle is unique. We’ve never done a reusable vehicle this large. It was also not initially planned for the lunar mission; it was planned for the Mars mission.”
Musk’s long-term vision remains fixed on Mars colonization, a goal he frames as essential for humanity’s survival. Yet congressional priorities and NASA’s “Moon to Mars” roadmap ensure that the lunar return is a prerequisite. Technical hurdles, legislative mandates, and the sheer complexity of the mission mean that every Starship test—whether it ends in triumph or debris—carries weight in determining whether Artemis III can meet its 2027 target.
