This project will develop piezoelectric-based power conversion for small power systems on the lunar surface. These piezoelectric systems can potentially offer high power density to significantly reduce size, weight, and cost. They can also offer high efficiency as well as resistance to the extreme lunar environment with its expected prolonged exposure to extreme cold and radiation. The effort will build and test prototype piezoelectric DC-to-DC power converters and DC-to-DC power supplies.

Researchers from NASA’s Jet Propulsion Laboratory in Southern California, private companies, and academic institutions are developing the first space-based quantum sensor for measuring gravity. Supported by NASA’s Earth Science Technology Office (ESTO), this mission will mark a first for quantum sensing and will pave the way for groundbreaking observations of everything from petroleum reserves to global supplies of fresh water.
A map of Earth’s gravity. Red indicates areas of the world that exert greater gravitational pull, while blue indicates areas that exert less. A science-grade quantum gravity gradiometer could one day make maps like this with unprecedented accuracy. Image Credit: NASA Earth’s gravitational field is dynamic, changing each day as geologic processes redistribute mass across our planet’s surface. The greater the mass, the greater the gravity.
You wouldn’t notice these subtle changes in gravity as you go about your day, but with sensitive tools called gravity gradiometers, scientists can map the nuances of Earth’s gravitational field and correlate them to subterranean features like aquifers and mineral deposits. These gravity maps are essential for navigation, resource management, and national security.
“We could determine the mass of the Himalayas using atoms,” said Jason Hyon, chief technologist for Earth Science at JPL and director of JPL’s Quantum Space Innovation Center. Hyon and colleagues laid out the concepts behind their Quantum Gravity Gradiometer Pathfinder (QGGPf) instrument in a recent paper in EPJ Quantum Technology.
Gravity gradiometers track how fast an object in one location falls compared to an object falling just a short distance away. The difference in acceleration between these two free-falling objects, also known as test masses, corresponds to differences in gravitational strength. Test masses fall faster where gravity is stronger.
QGGPf will use two clouds of ultra-cold rubidium atoms as test masses. Cooled to a temperature near absolute zero, the particles in these clouds behave like waves. The quantum gravity gradiometer will measure the difference in acceleration between these matter waves to locate gravitational anomalies.
Using clouds of ultra-cold atoms as test masses is ideal for ensuring that space-based gravity measurements remain accurate over long periods of time, explained Sheng-wey Chiow, an experimental physicist at JPL. “With atoms, I can guarantee that every measurement will be the same. We are less sensitive to environmental effects.”
Using atoms as test masses also makes it possible to measure gravity with a compact instrument aboard a single spacecraft. QGGPf will be around 0.3 cubic yards (0.25 cubic meters) in volume and weigh only about 275 pounds (125 kilograms), smaller and lighter than traditional space-based gravity instruments.
Quantum sensors also have the potential for increased sensitivity. By some estimates, a science-grade quantum gravity gradiometer instrument could be as much as ten times more sensitive at measuring gravity than classical sensors.
The main purpose of this technology validation mission, scheduled to launch near the end of the decade, will be to test a collection of novel technologies for manipulating interactions between light and matter at the atomic scale.
“No one has tried to fly one of these instruments yet,” said Ben Stray, a postdoctoral researcher at JPL. “We need to fly it so that we can figure out how well it will operate, and that will allow us to not only advance the quantum gravity gradiometer, but also quantum technology in general.”
This technology development project involves significant collaborations between NASA and small businesses. The team at JPL is working with AOSense and Infleqtion to advance the sensor head technology, while NASA’s Goddard Space Flight Center in Greenbelt, Maryland is working with Vector Atomic to advance the laser optical system.
Ultimately, the innovations achieved during this pathfinder mission could enhance our ability to study Earth, and our ability to understand distant planets and the role gravity plays in shaping the cosmos. “The QGGPf instrument will lead to planetary science applications and fundamental physics applications,” said Hyon.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Gateway’s HALO (Habitation and Logistics Outpost) arrives in Mesa, Arizona, after traveling from Italy, where Thales Alenia Space fabricated its primary structure. Delivered by cargo aircraft to Phoenix-Mesa Gateway Airport, HALO will be transported to Northrop Grumman’s facility in Gilbert for final outfitting.Josh Valcarcel A core component of Gateway, humanity’s first space station around the Moon, is now on American soil and one step closer to launch. In lunar orbit, Gateway will support NASA’s Artemis campaign to return humans to the Moon and chart a path of scientific discovery toward the first crewed missions to Mars.
Gateway’s first pressurized module and one of its two foundational elements, HALO (Habitation and Logistics Outpost), arrived in Arizona on April 1. Fresh off a transatlantic journey from Thales Alenia Space in Turin, Italy, the structure will undergo final outfitting at Northrop Grumman’s integration and test facility before being integrated with Gateway’s Power and Propulsion Element at NASA’s Kennedy Space Center in Florida. The pair of modules will launch together on a SpaceX Falcon Heavy rocket.

It will offer command and control, data handling, energy storage, electrical power distribution, thermal regulation, and communications and tracking via Lunar Link, a high-rate lunar communication system provided by ESA (European Space Agency). The module will include docking ports for visiting vehicles such as NASA’s Orion spacecraft, lunar landers, and logistics modules. It will also support both internal and external science payloads, enabling research and technology demonstrations in the harsh deep space environment.
Built with industry and international partners, Gateway will support sustained exploration of the Moon, serve as a platform for science and international collaboration, and act as a proving ground for the technologies and systems needed for future human missions to Mars.

NASA’s Electrodynamic Dust Shield (EDS) successfully demonstrated its ability to remove regolith, or lunar dust and dirt, from its various surfaces on the Moon during Firefly Aerospace’s Blue Ghost Mission 1, which concluded on March 16. Lunar dust is extremely abrasive and electrostatic, which means it clings to anything that carries a charge. It can damage everything from spacesuits and hardware to human lungs, making lunar dust one of the most challenging features of living and working on the lunar surface. The EDS technology uses electrodynamic forces to lift and remove the lunar dust from its surfaces. The first image showcases the glass and thermal radiator surfaces, coated in a layer of regolith. As you slide to the left, the photo reveals the results after EDS activation. Dust was removed from both surfaces, proving the technology’s effectiveness in mitigating dust accumulation.
This milestone marks a significant step toward sustaining long-term lunar and interplanetary operations by reducing dust-related hazards to a variety of surfaces for space applications ranging from thermal radiators, solar panels, and camera lenses to spacesuits, boots, and helmet visors. The EDS technology is paving the way for future dust mitigation solutions, supporting NASA’s Artemis campaign and beyond. NASA’s Electrodynamic Dust Shield was developed at Kennedy Space Center in Florida with funding from NASA’s Game Changing Development Program, managed by the agency’s Space Technology Mission Directorate.
