NASA announced Tuesday the selection of three new science investigations that will strengthen humanity's understanding and exploration of the Moon. As part of the agency's CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign, American companies will deliver these research payloads to the lunar surface no earlier than 2028.
"With CLPS, NASA has been taking a new approach to lunar science, relying on U.S. industry innovation to travel to the surface of the Moon and enable scientific discovery," said Joel Kearns, deputy associate administrator for exploration, Science Mission Directorate, NASA Headquarters in Washington. "These selections continue this pipeline of lunar exploration, through research that will not only expand our knowledge about the Moon's history and environment, but also inform future human safety and navigation on the Moon and beyond."
The selected scientific payloads are:
- Emission Imager for Lunar Infrared Analysis in 3D (EMILIA-3D). The EMILIA-3D payload will create three-dimensional thermal models of the lunar terrain, using a thermal imager to measure the temperature of the landscape coupled with a stereo pair of visible-light cameras. These models will help the U.S. better image and navigate the Moon's surface through improved understanding of the properties of the dusty lunar soil, called regolith, and what temperature measurements convey about the lunar surface. The principal investigator is Andrew Ryan at the University of Arizona.
- Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity (LISTER). The LISTER instrument will measure the heat flow of the Moon's interior by drilling beneath the lunar surface, pausing at intervals to measure temperature changes and the ability of the subsurface material to conduct heat. A previous version of LISTER flew on the Blue Ghost Mission 1 CLPS delivery to the Moon's near side, where it took eight temperature and thermal conductivity measurements and drilled down to about three feet beneath the lunar surface. This new LISTER investigation will study the heat flow generated by the Moon itself, giving us a better understanding of its thermal history. The principal investigator is Seiichi Nagihara at Texas Tech University.
- Site-agnostic Energetic Lunar Ion and Neutron Environment (SELINE). The SELINE payload will provide new insight into the Moon's radiation environment by studying, for the first time at the lunar surface, the radiation from both primary galactic cosmic rays and their secondary particles and how this radiation interacts with the lunar regolith. Data from SELINE will improve our understanding of the planetary processes at work on the Moon, as well as inform space weather preparation and safety for long-term human exploration of the lunar surface. The principal investigator is Drew Turner at Johns Hopkins University.
These science experiments, selected through NASA's Payloads and Research Investigations on the Surface of the Moon call for proposals, do not require a specific landing site on the lunar surface to gather their data, and NASA will assign them to specific CLPS delivery task orders at a later time.
NASA uses CLPS to send scientific instruments and technology demonstrations to advance capabilities for science, exploration, or commercial development of the Moon and beyond. By supporting a steady cadence of lunar deliveries, the agency will continue to enable a growing lunar economy while leveraging the entrepreneurial innovation of the commercial space industry.
