The Astrobotic Peregrine is a class of robotic lunar landers designed and operated by Astrobotic Technology to deliver small payloads to the Moon's surface. It gained significance as part of NASA's Commercial Lunar Payload Services (CLPS) program, with three task orders awarded to Astrobotic for Peregrine-class missions. The first mission, Peregrine Mission One, launched in January 2024 but failed to reach the Moon due to a propellant leak shortly after deployment.

Lore & Background

The Peregrine lander is approximately 2.5 meters wide and 1.9 meters tall, with a mechanical structure made of aluminum alloy and four landing legs. It uses five pressure-fed hypergolic main engines and twelve RCS thrusters, with propellant stored in four tanks (two each for fuel and oxidizer) and a fifth tank for high-pressure helium. Electrical power comes from solar cells stored in a lithium-ion battery, with solar panel configurations varying by intended landing site. Communication with Earth uses X-Band radio frequencies, including multiple low gain antennas for cruise and lunar orbit operations and a higher gain antenna for surface communication.

Reader's Guide

The Astrobotic Peregrine lander represents a key element in NASA's strategy to engage commercial partners for lunar delivery services under the CLPS program. In November 2018, NASA announced nine companies eligible for CLPS task orders, and in May 2019 Astrobotic received Task Order 2-AB initially valued at $79.5 million. The first Peregrine mission launched in January 2024 but failed due to a propellant leak. Despite this setback, NASA awarded two additional Peregrine task orders in June 2026, reported as a combined $297.9 million award. The lander's design, capable of delivering 100 kg to a polar landing site, underscores its role in enabling small payload science and technology demonstrations on the Moon. Its legacy is tied to the evolving public-private partnership model for space exploration, though its operational success remains incomplete as of the available record.

Origins: From a Carnegie Mellon Lab to Lunar Ambition

Astrobotic traces its roots to 2007, when Carnegie Mellon professor Red Whittaker and a small team of associates set out with a bold aim: to become the first commercial entity to touch down on the Moon. Their initial target was the Google Lunar X Prize. That same year they built a running prototype called Red Rover and rebranded their concept lander from Artemis to Griffin. Early NASA support arrived quickly — a 2008 concept-study grant on regolith-moving methods, followed by Small Business Innovation Research awards totaling over $795,000 for lunar resource prospecting studies that produced the Polar Excavator concept. In 2010 NASA issued an ILDD contract worth up to $30.1 million, and in 2011 the company earned a NIAC Phase I selection for exploring skylights, lava tubes, and caves. By 2014, Astrobotic was one of three firms chosen for NASA's Lunar CATALYST initiative, a no-funds-exchanged Space Act Agreement that kept the Griffin lander in active development.

The Peregrine Flight and Its End

The Peregrine lander finally lifted off on January 8, 2024, riding the maiden flight of the Vulcan Centaur rocket from Launch Complex 41 at Space Force Station in Florida. The vehicle had been selected under NASA's Commercial Lunar Payload Services program, and its journey was meant to carry science and technology payloads toward Lacus Mortis. However, a propellant leak during the mission prevented the lander from ever reaching the Moon, whether for a soft touchdown or a hard impact. The spacecraft remained trapped in its original highly elliptical Earth orbit and was ultimately brought down in a controlled atmospheric reentry over the Pacific Ocean on January 18, 2024. The path to that single launch had been long and turbulent: the original target of a 2021 debut slipped to 2022 amid payload and engine testing issues, and a December 2023 wet dress rehearsal exposed ground-systems problems that pushed the window into 2024.

Contracts, Partnerships, and the VIPER Chapter

Astrobotic's commercial trajectory was shaped by a series of high-profile agreements. In November 2018 the company won a $79.5 million CLPS contract to deliver up to fourteen payloads to Lacus Mortis, with an initial target launch in mid-2021. Partnerships broadened quickly: Airbus Defence and Space signed an engineering-support memorandum in 2016, Spacebit agreed in 2019 to ride the first UK lunar rover Asagumo aboard Peregrine, and YouTuber MrBeast pledged a hard-drive payload in early 2021. In June 2020 NASA awarded a second CLPS contract worth $199.5 million to carry the VIPER rover, targeting a November 2024 landing. That plan evaporated in July 2024 when NASA cancelled VIPER. Meanwhile, in September 2022 Astrobotic acquired the bankrupt Masten Space Systems, absorbing its propulsion and test operations, including the Broadsword 110 kN 3D-printed aluminum engine.

Beyond Peregrine: Luna Grid and a New Corporate Chapter

Even as the Peregrine mission ended in the Pacific, Astrobotic was already sketching its next chapter. In 2024 the company unveiled the Luna Grid service, a concept that pairs its landers and rovers with Vertical Array Solar Panels to deliver what it describes as sustainable power on the lunar surface. The vision extends beyond a single landing to a persistent, grid-like energy infrastructure for future explorers. On the corporate side, the company's story took a definitive turn in June 2026, when it was announced that Voyager Technologies would acquire Astrobotic. The acquisition caps a nearly two-decade arc that began in a Carnegie Mellon lab in 2007, passed through X Prize ambitions, NASA CATALYST agreements, a failed first lunar attempt, and the loss of the VIPER contract, and now folds the Pittsburgh-based robotics team into a larger aerospace entity.

Frequently Asked Questions

What is the Astrobotic Peregrine?

The Peregrine is a class of small robotic lunar landers built and operated by Astrobotic Technology, purpose-built to carry compact scientific payloads to the Moon's polar regions. Rather than a single vehicle, it represents a repeatable platform designed for commercial delivery missions to the lunar surface.

What happened to Peregrine Mission One?

Peregrine Mission One launched in January 2024 but never reached the Moon. A propellant leak developed shortly after the lander separated from its launch vehicle, ending the mission in failure before it could enter lunar orbit.

How big is a Peregrine lander and what can it carry?

Each Peregrine vehicle stands about 1.9 meters (roughly 6 feet 3 inches) tall and spans 2.5 meters (around 8 feet 2 inches) wide. It is rated to deliver up to 100 kilograms of payload to a polar landing site on the lunar surface.

Why is the Peregrine significant in NASA's lunar program?

The Peregrine serves as a core vehicle in NASA's Commercial Lunar Payload Services program, which outsources small-payload delivery to private companies. Astrobotic has been awarded three separate CLPS task orders for Peregrine-class missions, making it one of the principal commercial routes for getting instruments to the Moon.

How many Peregrine missions have flown so far?

Only one Peregrine mission has been attempted to date: Peregrine Mission One in January 2024, which was lost to a propellant leak shortly after launch. The remaining two CLPS task orders for Peregrine-class landers have not yet flown.
