Engineers conduct a mass properties test on the Mass Spectrometer Observing Lunar Operations (MSolo) instrument inside Kennedy Space Center’s Space Station Processing Facility in Florida on Nov. 22, 2022. Mass properties determines the mass and center of gravity of the flight unit. The lander uses this information, from all payloads, to improve stability and performance of the lander – and to a lesser degree, the stability and performance of the rocket. This marks the end of testing at Kennedy for the Polar Resources Ice Mining Experiment-1 (PRIME-1) MSolo instrument. It will soon be shipped to Intuitive Machines in Houston for integration on the NOVA-C landing platform. Launching in 2023, the PRIME-1 mission will be the first in-situ resource utilization demonstration on the Moon.
