Peregrine 1 (CLPS 1)

Peregrine 1 [Astrobotic Technology]

Peregrine is a lunar lander privately developed by Astrobotic Technology for the Google Lunar-X-Prize.

The Peregrine Lunar Lander will fly 35 kilograms of customer payloads on its first mission, with the option to upgrade to 265 kilograms on future missions. Already 11 deals from six nations have been signed for this 2019 mission. The first mission in 2019 will serve as a key demonstration of service for NASA, international space agencies, and companies looking to carry out missions to the Moon.

Peregrine is powered by an Aerojet Rocketdyne propulsion system featuring next generation space engine technology. Peregrine has four tanks surrounding a cluster of five Aerojet Rocketdyne ISE-100 engines based on the Divert and Attitude Control System thrusters it developed for missile defense applications. Clusters of ISE-5 attitude control thrusters orient the craft. The main engines are concentric with the spacecraft central axis and perform translunar injection, trajectory correction maneuvers, lunar orbit insertion, de-orbit, brake, and decent.

In July 2017 Astrobotic Technology announced, that they have selected ULA to launch the Peregrine mission in 2019 on a shared Atlas-5 rocket, which is too late for the Google Lunar X Prize, but which will serve as a pathfinder for future commercialization.

In May 2019, Astrobotic's Peregrine was selected by NASA's Commercial Lunar Payload Services (CLPS) program to deliver up to 14 payloads to Lacus Mortis by July 2021 to support the Artemis lunar program. The Peregrine lander might be launched either on a shared or dedicated launch vehicle. In August 2019 it was announced, that Peregrine 1 will fly on the maiden Vulcan Centaur VC2S rocket, on a shared launch. In early 2023 a new landing site was selected, which increases the scientific value of the NASA payloads. The new landing site will be outside of the Gruithuisen Domes, a geologic enigma along the mare/highlands boundary on the northeast border of Oceanus Procellarum.

Following NASA payloads have been selected for the mission:

  • Laser Retroreflector Array (LRA) - Goddard Space Flight Center (GSFC)
  • Neutron Spectrometer System (NSS): NSS will search for indications of water-ice near the lunar surface by measuring how much hydrogen-bearing materials are at the landing site as well as determine the overall bulk composition of the regolith there. NSS is being developed at NASA Ames.
  • Linear Energy Transfer Spectrometer (LETS): The LETS radiation sensor will collect information about the lunar radiation environment and relies on flight-proven hardware that flew in space on the Orion spacecraft’s inaugural uncrewed flight in 2014. It is being developed at NASA Johnson.
  • Near-Infrared Volatile Spectrometer System (NIRVSS): NIRVSS will measure surface and subsurface hydration, carbon dioxide and methane – all resources that could potentially be mined from the Moon — while also mapping surface temperature and changes at the landing site. It is being developed at Ames Research Center in Silicon Valley, California.
  • PROSPECT Ion-Trap Mass Spectrometer (PITMS) for Lunar Surface Volatiles: PITMS will characterize the lunar exosphere after descent and landing and throughout the lunar day to understand the release and movement of volatiles. It was previously developed for ESA’s Rosetta mission and is being modified for this mission by NASA Goddard and ESA.

Also on board will be DLR's M-42 radiation detector.
