LunIR

LunIR (Lunar InfraRed Imaging, formerly known as SkyFire) is a nanosatellite spacecraft launched to the Moon collecting surface spectroscopy and thermography. It was launched as a secondary payload on the Artemis 1 mission on 16 November 2022.

Mission
LunIR is a technology demonstration mission funded by NASA that uses a low-cost 6U CubeSat spacecraft. LunIR will perform a lunar flyby, collecting spectroscopy and thermography for surface characterization, remote sensing, and site selection. The spacecraft includes two deployable solar panels and will have a total mass of about 14 kg.

LunIR was selected in April 2015 by NASA's NextSTEP program (Next Space Technologies for Exploration Partnerships) and awarded a contract to Lockheed Martin Space worth US$1.4 million for further development.

LunIR will communicate with Earth via ground stations operated by Kongsberg Satellite Services. LunIR will use 13-meter-diameter radio antennas located in Punta Arenas, Chile; Svalbard, Norway; and Troll station, Antarctica.

Launch
LunIR was launched as one of ten CubeSats as a secondary payload on the maiden flight of the Space Launch System, Artemis 1.

Propulsion
LunIR will demonstrate a low thrust electric propulsion technology called electrospray propulsion to lower the spacecraft's orbit for additional science and technology mission objectives.
