Blue Origin Shows Off Its MK1 Lunar Lander—and It’s Way Bigger Than Apollo’s

Riding the high of its show-stopping New Glenn flight earlier this month, Blue Origin is now aiming even higher—toward the Moon. Now, the company’s lunar ambitions seem more tangible than ever with the unveiling of the Blue Moon Mark 1 (MK1) lunar lander.

In an X post on Friday, Blue Origin owner and founder Jeff Bezos shared a first look at MK1. This 26-foot-tall (8-meter-tall) cargo lander is expected to embark on its first mission during the first quarter of 2026, touching down near the Shackleton crater at the Moon’s south pole.

Attempting this feat within the next four months will be high risk, high reward for Blue Origin. If Blue can pull off an uncrewed lunar landing before SpaceX, it could give the company a strategic advantage as NASA reevaluates lander providers for Artemis 3. But the tight timeline and complex hardware will present numerous challenges.

Bezos’s big lander

According to Bezos, MK1 is smaller than Blue Origin’s human lander, MK2, but larger than NASA’s Apollo lander. This single-launch spacecraft is designed to launch aboard New Glenn and ferry up to 3.3 tons (3 metric tons) of payload to the lunar surface.

The Blue Moon Pathfinder mission will demonstrate and validate the lander’s hardware and systems. This includes its never-before-flown BE-7 engine, cryogenic fluid power and propulsion systems, avionics, continuous downlink communications, and precision landing.

MK1 will also be carrying a NASA payload called SCALPSS (Stereo Cameras for Lunar Plume Surface Studies). This array of cameras will collect imagery during and after MK1’s descent, gathering critical data to assist future Moon landings and improve NASA’s understanding of how they affect the lunar surface.

MK1 is the largest commercial cargo lander ever built, capable of carrying far more payload than any of NASA’s Commercial Lunar Payload Services (CLPS) landers. MK1’s height could put it at greater risk of toppling over during its landing attempt, especially if its critical landing precision and control systems do not perform as expected.

Blue Origin will soon conduct “fully integrated checkout tests†of MK1, according to Bezos. This refers to ground tests that will evaluate performance for all the lander’s systems and hardware to ensure that it’s ready for flight.

This could help Blue anticipate and address issues during MK1’s deployment and landing attempt, but because it cannot fully replicate the lunar environment, unforeseen challenges could still arise.

Crunch time

Blue Origin’s goal of launching Blue Moon Pathfinder before the end of Q1 is very ambitious. Achieving an uncrewed lunar landing is a critical milestone that Blue ought not to rush, as ensuring mission success will require meticulous testing and validation of all systems.

Still, the timing appears to be right for several reasons. New Glenn achieved every single one of its mission objectives during its second test flight on November 13, indicating that it’s ready to launch a lunar landing mission. MK1’s development appears to be on track, and in theory, it could be ready to launch within the next several months—though ground testing could result in delays.

Perhaps the biggest motivator, however, is the Artemis 3 carrot dangling in front of Bezos’s face. NASA originally tapped SpaceX to build the Human Landing System (HLS) that will deliver the Artemis 3 astronauts to the Moon in mid-2027, but significant delays prompted the agency to reopen the contract in October.

Blue Origin has since stepped up to the plate. NASA Press Secretary Bethany Stevens previously told Gizmodo that the agency is evaluating plans from both SpaceX and Blue Origin for acceleration of Artemis 3 lander production. SpaceX detailed its plans to simplify the HLS architecture in late October, but leaked internal documents suggest the company still won’t be ready for an Artemis 3 launch until September 2028.

If NASA decides to go with Blue instead, it would be the company’s MK2 lander that would carry the Artemis 3 crew to the surface of the Moon. Demonstrating an uncrewed lunar landing with MK1 is a critical step toward the deployment of MK2, as these two landers share much of the same systems and hardware.

Hitting this milestone within the next four months would certainly give Blue a competitive edge, as SpaceX is nowhere close to a lunar landing. Still, Bezos ought not to let ambition get in the way of the Pathfinder mission’s success—especially with a NASA payload onboard. Failure could set the company’s lunar program back years.
