NASA announced Tuesday the selection of three companies to land four new missions on the Moon in late 2028 as part of its Moon Base Program. Astrobotic, Firefly Aerospace, and Intuitive Machines will deliver NASA science payloads to the lunar surface, marking a step toward building the first outpost on another celestial world.

The agency's Human Spaceflight Mission Directorate is also seeking industry proposals through a new solicitation appendix, NextSTEP-3 B: Moon Base Demonstrations. The appendix calls for industry-led demonstrations, risk reduction, and special topic activities that enable an enduring human presence on the lunar surface.

The missions are scheduled for late 2028, though exact launch windows and durations were not disclosed. No information was provided on whether any of the selected companies have faced previous delays in similar NASA CLPS (Commercial Lunar Payload Services) contracts.

These awards represent a shift from short-duration robotic landers to infrastructure-building missions, laying groundwork for a permanent base. The selection leverages private-sector capabilities, with each company bringing distinct lander designs and propulsion systems, potentially reducing costs and accelerating timelines compared to traditional government-led development.

Critics may question whether the 2028 timeline is achievable, given that some CLPS missions have faced delays and technical challenges, and that a permanent lunar base requires significant advances in life support and power systems. The cost of these missions has not been released, and broader funding for the Moon Base Program remains subject to congressional appropriations.
