NASA Selects 2 Instruments for Artemis IV Lunar Surface Science
NASA has selected two science instruments designed for astronauts to deploy on the surface of the Moon during the Artemis IV mission to the lunar south polar region. The instruments will improve our knowledge of the lunar environment to support NASA’s further exploration of the Moon and beyond to Mars.

“The Apollo Era taught us that the further humanity is from Earth, the more dependent we are on science to protect and sustain human life on other planets,” said Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “By deploying these two science instruments on the lunar surface, our proving ground, NASA is leading the world in the creation of humanity’s interplanetary survival guide to ensure the health and safety of our spacecraft and human explorers as we begin our epic journey back to the Moon and onward to Mars.”
After his voyage to the Moon’s surface during Apollo 17, astronaut Gene Cernan acknowledged the challenge that lunar dust presents to long-term lunar exploration. Moon dust sticks to everything it touches and is very abrasive. The knowledge gained from the DUSTER (DUst and plaSma environmenT survEyoR) investigation will help mitigate hazards to human health and exploration. Consisting of a set of instruments mounted on a small autonomous rover, DUSTER will characterize dust and plasma around the landing site. These measurements will advance understanding of the Moon’s natural dust and plasma environment and how that environment responds to the human presence, including any disturbance during crew exploration activities and lander liftoff. The DUSTER instrument suite is led by Xu Wang of the University of Colorado Boulder. The contract is for $24.8 million over a period of three years.
A model of the DUSTER instrument suite consisting of the Electrostatic Dust Analyzer (EDA)—which will measure the charge, velocity, size, and flux of dust particles lofted from the lunar surface—and Relaxation SOunder and differentiaL VoltagE (RESOLVE)—which will characterize the average electron density above the lunar surface using plasma sounding. Both instruments will be housed on a Mobile Autonomous Prospecting Platform (MAPP) rover, which will be supplied by Lunar Outpost, a company based in Golden, Colorado, that develops and operates robotic systems for space exploration.

Data from the SPSS (South Pole Seismic Station) will enable scientists to characterize the lunar interior structure to better understand the geologic processes that affect planetary bodies. The seismometer will help determine the current rate at which the Moon is struck by meteorite impacts, monitor the real-time seismic environment and how it can affect operations for astronauts, and determine properties of the Moon’s deep interior. The crew will additionally perform an active-source experiment using a “thumper” that creates seismic energy to survey the shallow structure around the landing site. The SPSS instrument is led by Mark Panning of NASA’s Jet Propulsion Laboratory in Southern California. The award is for $25 million over a period of three years.

“These two scientific investigations will be emplaced by human explorers on the Moon to achieve science goals that have been identified as strategically important by both NASA and the larger scientific community”, said Joel Kearns, deputy associate administrator for exploration, Science Mission Directorate at NASA Headquarters. “We are excited to integrate these instrument teams into the Artemis IV Science Team.”
The two payloads were selected for further development to fly on Artemis IV; however, final manifesting decisions about the mission will be determined at a later date.
Through Artemis, NASA will address high priority science questions, focusing on those that are best accomplished by on-site human explorers on and around the Moon and by using the unique attributes of the lunar environment, aided by robotic surface and orbiting systems. The Artemis missions will send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.

In our entire solar system, the only object that shines with its own light is the Sun. That light always beams onto Earth and the Moon from the direction of the Sun, illuminating half of our planet in its orbit and reflecting off the surface of the Moon to create moonlight. Sometimes the entire face of the Moon glows brightly. Other times we see only a thin crescent of light. Sometimes the Moon seems to disappear. These shifts are called Moon phases. The waxing gibbous phase comes just before the full moon.
One year after winning second place in NASA’s Break the Ice Lunar Challenge, members of the small business Starpath visited NASA’s Marshall Space Flight Center in Huntsville, Alabama, as part of their prize opportunity to test their upgraded lunar regolith excavation and transportation rover in the center’s 20-foot thermal vacuum chamber.
The technology startup headquartered in Hawthorne, California, won second place overall at the Break the Ice Lunar Challenge’s live demonstration and finale in June 2024. This competition, one of NASA’s Centennial Challenges, tasked competitors to design, build, and demonstrate robotic technologies that could excavate and transport the icy, rocky dirt – otherwise known as regolith – found on the Moon.

“NASA’s Centennial Challenges are a great way to discover new, innovative technologies, including those for future use on the Moon and even Mars,” said Naveen Vetcha, Break the Ice Lunar Challenge manager at NASA Marshall. “Working with winners after the challenge concludes is a perfect example of how we can use NASA facilities to continue advancing these technologies to generate valuable solutions for the agency and industry.”
Starpath built a four-wheeled rover capable of excavating, collecting, and hauling material under extremely harsh environmental conditions that simulate the lunar South Pole. On the rover, a dual drum barrel can extend from the body of the robot – mimicking a movement similar to a crab’s claws – and scrape into rough, hard regolith to excavate material quickly without compromising finite battery life.
Before Starpath made the 2,000-mile drive from California to Alabama this summer, NASA Marshall’s Engineering Test Facility staff prepared a concrete slab outfitted with rocky terrain to act as a testbed for the robot to interact inside the chamber. The V-20 Thermal Vacuum Chamber, located at Marshall’s Environmental Test Facility, can simulate harsh environments by manipulating the chamber’s vacuum, temperature, humidity, and pressure effects. Starpath staff spent about three days at NASA Marshall in August, testing their robot with excavation and mobility trials while collecting data on its performance.
The Starpath team is honing the development of its technology for missions located at the permanently shadowed regions of the lunar South Pole. As a future landing site for NASA’s Artemis missions, which will send astronauts to the Moon and prepare to send the first Americans to Mars, the South Pole region of the Moon is known to contain ice within its regolith. This was the leading inspiration behind the development of the Break the Ice Lunar Challenge, as NASA will require robust technologies that can excavate and transport lunar ice for extraction, purification, and use as drinking water or rocket fuel.
Starpath, one of three winning teams in NASA’s Break the Ice Lunar Challenge, was invited by NASA Centennial Challenges to test their lunar excavation and traversal rover at the agency’s thermal vacuum chamber facility at NASA’s Marshall Space Flight Center in Huntsville, Alabama. The invitation was an added perk to the team’s successful participation in Break the Ice, which took place from 2020 to 2024. A space hardware startup from Hawthorne, California, Starpath won a cumulative $838,461 across three levels of Phase 2 before winning second place overall at the challenge’s live demonstration and finale in June 2024.
