Lunar Compact Infrared Imaging System (L-CIRiS)

IM-4 ยท manifested ยท NASA payload

A multispectral thermal-infrared imaging radiometer on a rotating stage on the lander deck. It scans 360-degree panoramas and maps surface temperature (from -170 to +100 C), silicate mineral composition and thermal inertia (soil density) at under 1 cm per pixel near the lander, using an uncooled microbolometer with on-board calibration.

PI: Paul O. Hayne (LASP, University of Colorado)
Built by: University of Colorado Boulder, Laboratory for Atmospheric and Space Physics (LASP), which manages the project; the instrument was built by Ball Aerospace (now BAE Systems) under subcontract (university)

Technology thermal infrared imaging radiometer (science and site reconnaissance)
Moon Base need DN-003 L, DN-010 L, DN-008 L (The study's reading. NASA says L-CIRiS will help find compounds that could supply water, oxygen and building materials and will 'identify potential exploration hazards'; its team says it will help plan landers, rovers and astronaut missions by finding hazardous rocks and soil density. Its South Pole thermal panoramas touch DN-003 L (time-resolved thermal mapping, a remote-sensing gap, so only in part), its mineral maps DN-010 L, and its thermal-inertia soil density DN-008 L. One site, one lunar day. IM-4 is not on NASA's Moon Base phases page; its 2027 date falls in Phase 1 ('Now through 2028'), which is the study's reading.)
Route onto CLPS LSITP; One of the 12 Lunar Surface Instrument and Technology Payloads selected on 1 July 2019 (ROSES-2018). NASA first manifested it on Masten Space Systems' XL-1 lander (task order of 8 April 2020, for a 2022 South Pole landing). Masten went bankrupt in 2022, its payloads were re-manifested, and L-CIRiS moved to the CP-22 task order awarded to Intuitive Machines on 29 August 2024.; 2019-07-01

Flights before the Moon

  • Earth orbit or deep space: CIRiS on a CubeSat in low Earth orbit (Ball Aerospace, ESTO InVEST), 2019-12-05. The radiometer design L-CIRiS adapts, built by the same company: an uncooled 7.5-13 micron imaging radiometer with on-board calibration (carbon-nanotube blackbody, high-emissivity flat panels), flown to show calibrated thermal imaging from a small spacecraft. TechPort rates it TRL 9. L-CIRiS adds a panoramic scan stage and a temperature-controlled enclosure for the Moon.

Heritage hardware

  • design heritage (aircraft instrument): CIRiS itself was based on a Ball instrument flown on aircraft, modified for space. Who funded that aircraft instrument is not stated.

Funding before the lunar flight

  • NASA Marshall contract to the University of Colorado for L-CIRiS (80MSFC20C0016), the LSITP award. Linked by name: the description names L-CIRiS. It covers the Ball-built instrument through 2026; subawards reported are two small ones to the University of Central Florida for science support ($33,458 each). The Ball subcontract value is not reported. (SMD LSITP; 2020-2026): $5,029,295

FO's role

Grade: none. No FO project, flight or report names L-CIRiS, CIRiS, its PI, LASP's L-CIRiS team or Ball's radiometer team. Its flight test before the Moon was an ESTO InVEST CubeSat in low Earth orbit, not FO. The study's earlier traceback grade (none found) stands; this study resolves an earlier open question: Ball's fact sheet and the team's 2020 abstract do tie L-CIRiS to CIRiS.
