Stereo Cameras for Lunar Plume Surface Studies (SCALPSS)


Mission Name: Intuitive Machines 1 (Odysseus)


Stereo Cameras for Lunar Plume Surface Studies (SCALPSS) are primarily an engineering experiment to determine the effects of the lander's plume on the lunar surface during landings. SCALPSS comprises a suite of four cameras that will image the plume as the lander reaches the surface and continue through engine shut-off. The images from four different perspectives will allow 3D models of the landing site to be made, before and after landing.

The four cameras are mounted on the lander so as to be able to provide stereo coverage (two pairs of stereo cameras) and to image 84% of the surface below the lander, a total of about 13 square meters. The cameras will turn on 30 seconds before touchdown and continue to operate after landing. The cameras are identical, FLIR Chameleon3 with 3.2 MP CMOS sensors and 3.37 mm focal length lenses (Peau Productions GP33728). They are arranged to provide 3D images.

The Intuitive Machines 1 Odysseus lander touched down on the Moon on February 22. Due to a hardware issue, SCALPSS was unable to collect any data during the landing.
