INFICON Holding AG said its Transpector MPH commercial off-the-shelf quadrupole mass spectrometer, powering NASA’s MSolo instrument on Intuitive Machines’ IM-2 Athena lander, successfully operated during transit and for several hours on the lunar surface after the March 6, 2025 south-pole landing attempt. The company reported the instrument collected 136 full spectra of gas composition and volatile data from space and at the lunar surface, though planned subsurface measurements could not be made because the lander tipped onto its side and the drill was not activated. These results have already been presented in the announcement.
