The Astrobotic Peregrine robotic spacecraft are a class of lunar landers designed and operated by Astrobotic Technology to deliver small payloads to the surface of the Moon. NASA has awarded three Commercial Lunar Payload Services (CLPS) task orders to Astrobotic for Peregrine-class missions. The first mission, Peregrine Mission One, launched in January, 2024. That mission experienced a propellant leak shortly after the lander was deployed into orbit, and did not reach the Moon. The other two Peregrine task orders were awarded to Astrobotic in June, 2026.
Funding In November, 2018 NASA announced that nine companies, including Astrobotic, were eligible for CLPS task orders. In May, 2019 Astrobotic was awarded CLPS Task Order 2-AB, initially valued at $79.5 million. The two missions assigned to Peregrine in June, 2026 were reported as being a combined $297.9 million award.
Design The Peregrine lander is approximately wide and tall. Astrobotic asserts a Peregrine lander can deliver to the lunar surface at a polar landing site.https://www.astrobotic.com/wp-content/uploads/2022/01/PUGLanders_011222.pdf
Structure The Peregrine mechanical structure is made of aluminum alloy, and includes four landing legs.
Propulsion Peregrine has five pressure-fed hypergolic main engines and twelve RCS thrusters. Propellant is contained in four tanks (two each for fuel and oxidizer) with a fifth tank for high-pressure helium.
Electrical power Electrical power provided by solar cells is stored in a lithium-ion battery. Solar panel configurations differ among landers, depending on the intended landing site.
Communication The lander communicates with Earth ground stations using X-Band radio frequencies. The design includes multiple low gain antennas for use during cruise and lunar orbit operations and a higher gain antenna to communicate from the lunar surface.
