Astrobotic's Peregrine: first US Moon-landing bet in 50 years fails in flight

Astrobotic is a Pittsburgh lunar-logistics company founded out of Carnegie Mellon robotics: it builds and operates robotic Moon landers, selling payload delivery to NASA and commercial customers.

That a private company could win NASA's fixed-price lunar delivery market — Astrobotic took the first CLPS launch slot and built Peregrine to land on the Moon in 2024.

The mission was funded primarily by NASA's $108M CLPS task order plus commercial payload sales — a fraction of Apollo's $25.8B (The Verge).

NASA created the Commercial Lunar Payload Services program to buy rides for its science instruments from private companies, and in 2019 selected Astrobotic to deliver five payloads. Astrobotic built the Peregrine lander around thrusters supplied by Frontier Aerospace and integrated by Dynetics, booked 20 payloads in total, and launched on ULA's new Vulcan Centaur rocket on January 8, 2024.

The launch itself was flawless — Vulcan's debut put Peregrine on its transfer trajectory — but hours after separation the lander could not orient to the sun, and Astrobotic traced the root cause to a propulsion-system failure causing critical propellant loss. Engineers stabilized the spacecraft enough to run payload and engineering operations, but a planned February 23 soft landing was off the table.

Peregrine never reached the Moon: it operated in space for about ten days before re-entering Earth's atmosphere, and the first successful private lunar landing instead went to Intuitive Machines the following month; Astrobotic continued toward its larger Griffin lander mission.

NASA's fixed-price CLPS model made the economics attractive but pushed all technical risk onto a startup flying a first-of-kind spacecraft on a one-shot trajectory.

The indirect low-energy trajectory demanded multiple propulsive maneuvers, so a small propulsion fault cascaded into loss of the whole mission profile.

Astrobotic's first-mover slot maximized visibility and prize — inaugural CLPS mission, first US attempt in five decades — but also guaranteed the harshest scrutiny when hardware failed.

Commercial payload sales spread the mission's risk across 20 customers, but no amount of revenue diversification could save a lander that could not maneuver.

Fixed-price government programs shift launch risk onto startups: winning the contract is not the moat — proven flight reliability is, and on a one-shot mission every subsystem is mission-critical.

After Peregrine re-entered Earth's atmosphere in January 2024, Astrobotic pivoted its remaining resources to Griffin, a larger lander slated for a NASA CLPS mission to the lunar south pole; NASA cancelled the VIPER rover that was to ride aboard Griffin in July 2024, but the company said it would continue the Griffin mission, which slipped to a late-2026 launch window as Astrobotic worked through post-flight reviews and new commercial customers.
