Credit: NASA/GRC/Sara Lowthian-Hanna NASA has awarded a total of $1.5 million to two U.S. teams for their novel technology solutions addressing energy distribution, management, and storage as part of the agency’s Watts on the Moon Challenge. The innovations from this challenge aim to support NASA’s Artemis missions, which will establish long-term human presence on the Moon.
This two-phase competition has challenged U.S. innovators to develop breakthrough power transmission and energy storage technologies that could enable long-duration Moon missions to advance the nation’s lunar exploration goals. The final phase of the challenge concluded with a technology showcase and winners’ announcement ceremony Friday at Great Lakes Science Center, home of the visitor center for NASA’s Glenn Research Center in Cleveland.
“Congratulations to the finalist teams for developing impactful power solutions in support of NASA’s goal to sustain human presence on the Moon,” said Kim Krome-Sieja, acting program manager for NASA Centennial Challenges at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “These technologies seek to improve our ability to explore and make discoveries in space and could have implications for improving power systems on Earth.”
The winning teams are:
First prize ($1 million): H.E.L.P.S. (High Efficiency Long-Range Power Solution) of Santa Barbara, California Second prize ($500,000): Orbital Mining Corporation of Golden, Colorado Four teams were invited to refine their hardware and deliver full system prototypes in the final stage of the competition, and three finalist teams completed their technology solutions for demonstration and assessment at NASA Glenn. The technologies were the first power transmission and energy storage prototypes to be tested by NASA in a vacuum chamber mimicking the freezing temperature and absence of pressure found at the permanently shadowed regions of the Lunar South Pole. The simulation required the teams’ power systems to demonstrate operability over six hours of solar daylight and 18 hours of darkness with the user three kilometers (nearly two miles) away from the power source.
During this competition stage, judges scored the finalists’ solutions based on a Total Effective System Mass (TESM) calculation, which measures the effectiveness of the system relative to its size and weight – or mass – and the total energy provided by the power source. The highest-performing solution was identified based on having the lowest TESM value – imitating the challenges that space missions face when attempting to reduce mass while meeting the mission’s electrical power needs.
Team H.E.L.P.S. (High Efficiency Long-Range Power Solution) from University of California, Santa Barbara, won the grand prize for their hardware solution, which had the lowest mass and highest efficiency of all competitors. The technology also featured a special cable operating at 800 volts and an innovative use of energy storage batteries on both ends of the transmission system. They also employed a variable radiation shield to switch between conserving heat during cold periods and disposing of excess heat during high power modes. The final 48-hour test proved their system design effectively met the power transmission, energy storage, and thermal challenges in the final phase of competition.
Orbital Mining Corporation, a space technology startup, received the second prize for its hardware solution that also successfully completed the 48-hour testwith high performance. They employed a high-voltage converter system coupled with a low-mass cable and a lithium-ion battery.
“The energy solutions developed by the challenge teams are poised to address NASA’s space technology priorities,” said Amy Kaminski, program executive for Prizes, Challenges, and Crowdsourcing in NASA’s Space Technology Mission Directorate at NASA Headquarters in Washington. “These solutions support NASA’s recently ranked civil space shortfalls, including in the top category of surviving and operating through the lunar night.”
During the technology showcase and winners’ announcement ceremony, NASA experts, media, and members of the public gathered to see the finalist teams’ technologies and hear perspectives from the teams’ participation in the challenge. After the winners were announced, event attendees were also welcome to meet NASA astronaut Stephen Bowen.

5 Min Read Reinventing the Clock: NASA’s New Tech for Space Timekeeping
The Optical Atomic Strontium Ion Clock is a higher-precision atomic clock that is small enough to fit on a spacecraft. Credits: NASA/Matthew Kaufman Here on Earth, it might not matter if your wristwatch runs a few seconds slow. But crucial spacecraft functions need accuracy down to one billionth of a second or less. Navigating with GPS, for example, relies on precise timing signals from satellites to pinpoint locations. Three teams at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, are at work to push timekeeping for space exploration to new levels of precision.
One team develops highly precise quantum clock synchronization techniques to aid essential spacecraft communication and navigation. Another Goddard team is working to employ the technique of clock synchronization in space-based platforms to enable telescopes to function as one enormous observatory. The third team is developing an atomic clock for spacecraft based on strontium, a metallic chemical element, to enable scientific observations not possible with current technology. The need for increasingly accurate timekeeping is why these teams at NASA Goddard, supported by the center’s Internal Research and Development program, hone clock precision and synchronization with innovative technologies like quantum and optical communications.
Syncing Up Across the Solar System
“Society requires clock synchronization for many crucial functions like power grid management, stock market openings, financial transactions, and much more,” said Alejandro Rodriguez Perez, a NASA Goddard researcher. “NASA uses clock synchronization to determine the position of spacecraft and set navigation parameters.”
If you line up two clocks and sync them together, you might expect that they will tick at the same rate forever. In reality, the more time passes, the more out of sync the clocks become, especially if those clocks are on spacecraft traveling at tens of thousands of miles per hour. Rodriguez Perez seeks to develop a new way of precisely synchronizing such clocks and keeping them synced using quantum technology.
Work on the quantum clock synchronization protocol takes place in this lab at NASA’s Goddard Space Flight Center in Greenbelt, Md.NASA/Matthew Kaufman In quantum physics, two particles are entangled when they behave like a single object and occupy two states at once. For clocks, applying quantum protocols to entangled photons could allow for a precise and secure way to sync clocks across long distances.
The heart of the synchronization protocol is called spontaneous parametric down conversion, which is when one photon breaks apart and two new photons form. Two detectors will each analyze when the new photons appear, and the devices will apply mathematical functions to determine the offset in time between the two photons, thus synchronizing the clocks.
While clock synchronization is currently done using GPS, this protocol could make it possible to precisely synchronize clocks in places where GPS access is limited, like the Moon or deep space.
Syncing Clocks, Linking Telescopes to See More than Ever Before
When it comes to astronomy, the usual rule of thumb is the bigger the telescope, the better its imagery.
“If we could hypothetically have a telescope as big as Earth, we would have incredibly high-resolution images of space, but that’s obviously not practical,” said Guan Yang, an optical physicist at NASA Goddard. “What we can do, however, is have multiple telescopes in various locations and have each telescope record the signal with high time precision. Then we can stich their observations together and produce an ultra-high-res image.”
The idea of linking together the observations of a network of smaller telescopes to affect the power of a larger one is called very long baseline interferometry, or VLBI.
For VLBI to produce a whole greater than the sum of its parts, the telescopes need high-precision clocks. The telescopes record data alongside timestamps of when the data was recorded. High-powered computers assemble all the data together into one complete observation with greater detail than any one of the telescopes could achieve on its own. This technique is what allowed the Event Horizon Telescope’s network of observatories to produce the first image of a black hole at the center of our galaxy.
The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole. Although the telescopes making up the EHT are not physically connected, they are able to synchronize their recorded data with atomic clocks.EHT Collaboration Yang’s team is developing a clock technology that could be useful for missions looking to take the technique from Earth into space which could unlock many more discoveries.
An Optical Atomic Clock Built for Space Travel
Spacecraft navigation systems currently rely on onboard atomic clocks to obtain the most accurate time possible. Holly Leopardi, a physicist at NASA Goddard, is researching optical atomic clocks, a more precise type of atomic clock.
While optical atomic clocks exist in laboratory settings, Leopardi and her team seek to develop a spacecraft-ready version that will provide more precision.
The team works on OASIC, which stands for Optical Atomic Strontium Ion Clock. While current spacecraft utilize microwave frequencies, OASIC uses optical frequencies.
The Optical Atomic Strontium Ion Clock is a higher-precision atomic clock that is small enough to fit on a spacecraft.NASA/Matthew Kaufman “Optical frequencies oscillate much faster than microwave frequencies, so we can have a much finer resolution of counts and more precise timekeeping,” Leopardi said.
The OASIC technology is about 100 times more precise than the previous state-of-the-art in spacecraft atomic clocks. The enhanced accuracy could enable new types of science that were not previously possible.
“When you use these ultra-high precision clocks, you can start looking at the fundamental physics changes that occur in space,” Leopardi said, “and that can help us better understand the mechanisms of our universe.”
The timekeeping technologies unlocked by these teams, could enable new discoveries in our solar system and beyond.
