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.

NASA’s SpaceX Crew-11 mission safely splashed down early Thursday morning in the Pacific Ocean off the coast of San Diego, concluding a more than five-month mission aboard the International Space Station.

NASA astronauts Zena Cardman and Mike Fincke, JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, and Roscosmos cosmonaut Oleg Platonov returned to Earth at 12:41 a.m. PST. Teams aboard SpaceX recovery vessels retrieved the spacecraft and its crew shortly after landing.

“I couldn’t be prouder of our astronauts and the teams on the ground at NASA, SpaceX, and across our international partnerships,” said NASA Administrator Jared Isaacman. “Their professionalism and focus kept the mission on track, even with an adjusted timeline. Crew-11 completed more than 140 science experiments that advance human exploration. Missions like Crew-11 demonstrate the capability inherent in America’s space program—our ability to bring astronauts home as needed, launch new crews quickly, and continue pushing forward on human spaceflight as we prepare for our historic Artemis II mission, from low Earth orbit to the Moon and ultimately Mars.”

Crew-11 returned home about a month earlier than planned because of a medical concern teams are monitoring with one of the crew members, who remains stable. Due to medical privacy, it is not appropriate for NASA to share more details about the crew member. Prior to return, NASA previously coordinated for all four crew members to be transported to a local hospital for additional evaluation, taking advantage of medical resources on Earth to provide the best care possible.

Following the planned overnight hospital stay, the crew members will return to NASA’s Johnson Space Center in Houston and undergo standard postflight reconditioning and evaluations.

The Crew-11 mission lifted off at 11:43 a.m. EDT on Aug.1, 2025, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. About 15 hours later, the crew’s SpaceX Dragon spacecraft docked to the orbital outpost at 1:27 a.m. CDT on Aug. 2.

During their 167-day mission, the four crew members traveled nearly 71 million miles and completed more than 2,670 orbits around Earth. The Crew-11 mission was Fincke’s fourth spaceflight, Yui’s second, and the first for Cardman and Platonov. Fincke has logged 549 days in space, ranking him fourth among all NASA astronauts for cumulative days in space.

Along the way, Crew-11 logged hundreds of hours of research, maintenance, and technology demonstrations. The crew members also celebrated the 25th anniversary of continuous human presence aboard the orbiting laboratory on Nov. 2, 2025. Research conducted aboard the space station advances scientific knowledge and demonstrates new technologies that enable us to prepare for human exploration of the Moon and Mars.

NASA’s Commercial Crew Program provides reliable access to space, maximizing the use of the International Space Station for research and development by partnering with private U.S. companies, including SpaceX, to transport astronauts to and from the space station.
