NASA said today it has selected Blue Origin to provide the second set of lunar landers for its multi-mission Artemis program to return Americans to the moon.

The fixed-price contract calls for $3.4 billion in NASA funding for two landers. Blue Origin is also putting up more than that amount of its own funding and has named its first lander the Blue Moon Lunar Lander, NASA said.

The company will send a first uncrewed test lander to the lunar surface before a four-person crew flies in 2029 on the Artemis V mission and lands in the second Blue Origin lander for a weeklong stay, NASA said. Both missions will launch atop Blue Origin’s New Glenn rocket now in development.

NASA has already contracted with SpaceX to build and launch the first commercial human lunar landing system for $2.9 billion. At least one of those astronauts will be the first woman on the moon. Another goal of the Artemis program includes landing the first person of color on the lunar surface.

“Having two distinct lunar lander designs, with different approaches to how they meet NASA’s mission needs, provides more robustness and ensures a regular cadence of Moon landings,” said Lisa Watson-Morgan, manager of the Human Landing System Program at NASA’s Marshall Space Flight Center in Huntsville. “This competitive approach drives innovation, brings down costs, and invests in commercial capabilities to grow the business opportunities that can serve other customers and foster a lunar economy.”

Billionaire Jeff Bezos, the founder of Amazon, owns Blue Origin. The company builds its BE-3 and BE-4 rocket engines in Huntsville and tests them at the Marshall Space Flight Center. The company leads what it calls the National Team working to return to the moon including team members Lockheed Martin, Northrop Grumman and Draper.
