Team H.E.L.P.S. (High Efficiency Long-Range Power Solution) from The University of California, Santa Barbara won the $1 million grand prize in NASA’s Watts on the Moon Challenge. Their team developed a low-mass, high efficiency cable and featured energy storage batteries on both ends of their power transmission and energy storage system. 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.
The Watts on the Moon Challenge is a NASA Centennial Challenge led by NASA Glenn. NASA Marshall Space Flight Center manages Centennial Challenges, which are part of the agency’s Prizes, Challenges, and Crowdsourcing program in the Space Technology Mission Directorate. NASA contracted HeroX to support the administration of this challenge.

NASA Develops Process to Create Very Accurate Eclipse Maps
New NASA research reveals a process to generate extremely accurate eclipse maps, which plot the predicted path of the Moon’s shadow as it crosses the face of Earth. Traditionally, eclipse calculations assume that all observers are at sea level on Earth and that the Moon is a smooth sphere that is perfectly symmetrical around its center of mass. As such, these calculations do not take into account different elevations on Earth or the Moon’s cratered, uneven surface.
For slightly more accurate maps, people can employ elevation tables and plots of the lunar limb — the edge of the visible surface of the Moon as seen from Earth. However, now eclipse calculations have gained even greater accuracy by incorporating lunar topography data from NASA’s LRO (Lunar Reconnaissance Orbiter) observations.
Using LRO elevation maps, NASA visualizer Ernie Wright at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, created a continuously varying lunar limb profile as the Moon’s shadow passes over the Earth. The mountains and valleys along the edge of the Moon’s disk affect the timing and duration of totality by several seconds. Wright also used several NASA data sets to provide an elevation map of Earth so that eclipse observer locations were depicted at their true altitude.
The resulting visualizations show something never seen before: the true, time-varying shape of the Moon’s shadow, with the effects of both an accurate lunar limb and the Earth’s terrain.
“Beginning with the 2017 total solar eclipse, we’ve been publishing maps and movies of eclipses that show the true shape of the Moon’s central shadow — the umbra,” said Wright.
A map showing the umbra (the Moon’s central shadow) as it passes over Cleveland at 3:15 p.m. local time during the April 8, 2024, total solar eclipse. NASA SVS/Ernie Wright and Michaela Garrison “And people ask, why does it look like a potato instead of a smooth oval? The short answer is that the Moon isn’t a perfectly smooth sphere.”
The mountains and valleys around the edge of the Moon change the shape of the shadow. The valleys are also responsible for Baily’s beads and the diamond ring, the last bits of the Sun visible just before and the first just after totality.
A computer simulation of Baily’s beads during a total solar eclipse. Data from Lunar Reconnaissance Orbiter makes it possible to map the lunar valleys that create the bead effect. NASA SVS/Ernie Wright Wright is lead author of a paper published September 19 in The Astronomical Journal that reveals for the first time exactly how the Moon’s terrain creates the umbra shape. The valleys on the edge of the Moon act like pinholes projecting images of the Sun onto the Earth’s surface.
A visualization of Sun images being projected from lunar valleys that are acting like pinhole projectors. Light rays from the Sun converge on each valley, then spread out again on their way to the Earth. NASA SVS/Ernie Wright The umbra is the small hole in the middle of these projected Sun images, the place where none of the Sun images reach.
Viewed from behind the Moon, the Sun images projected by lunar valleys on the Moon’s edge fall on the Earth’s surface in a flower-like pattern with a hole in the middle, forming the umbra shape. NASA SVS/Ernie Wright The edges of the umbra are made up of small arcs from the edges of the projected Sun images.
This is just one of several surprising results that have emerged from the new eclipse mapping method described in the paper. Unlike the traditional method invented 200 years ago, the new way renders eclipse maps one pixel at a time, the same way 3D animation software creates images. It’s also similar to the way other complex phenomena, like weather, are modeled in the computer by breaking the problem into millions of tiny pieces, something computers are really good at, and something that was inconceivable 200 years ago.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
SpaceX Crew-9 members (from left) Mission Specialist Aleksandr Gorbunov from Roscosmos and Commander Nick Hague from NASA pose for an official crew portrait at NASA’s Johnson Space Center in Houston, Texas.NASA/Josh Valcarel NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov are preparing to launch on the agency’s SpaceX Crew-9 mission to the International Space Station.
The flight is the ninth crew rotation mission with SpaceX to the station under NASA’s Commercial Crew Program. The duo will lift off aboard the SpaceX Dragon spacecraft, which previously flew NASA’s SpaceX Crew-4, Axiom Mission 2 and Axiom Mission 3, from Launch Complex 40 at Cape Canaveral Space Force Station in Florida.
Once aboard the space station, Hague and Gorbunov will become members of the Expedition 72 crew and perform research, technology demonstrations, and maintenance activities. The pair will join NASA astronauts Don Petitt, Butch Wilmore, Suni Williams, as well as Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner.
Wilmore and Williams, who launched aboard the Starliner spacecraft in June, will fly home with Hague and Gorbunov in February 2025.
Launch preparations are underway, and teams are working to integrate the spacecraft and the SpaceX Falcon 9 rocket, including checkouts of a second flight rocket booster for the mission. The integrated spacecraft and rocket will then be rolled to the pad and raised to the vertical position for a dry dress rehearsal with the crew and an integrated static fire test prior to launch.
The Crew
Nick Hague will serve as crew commander for Crew-9, making this his third launch and second mission to the space station. During his first launch in October 2018, Hague and his crewmate, Roscosmos’ Alexey Ovchinin, experienced a rocket booster failure, resulting in an in-flight, post-launch abort, ballistic re-entry, and safe landing in their Soyuz MS-10 spacecraft. Five months later, Hague launched aboard Soyuz MS-12 and served as a flight engineer aboard the space station during Expeditions 59 and 60. Hague has spent 203 days in space and conducted three spacewalks to upgrade space station power systems and install a docking adapter for commercial spacecraft.
Born in Belleville, Kansas, Hague earned a bachelor’s degree in Astronautical Engineering from the United States Air Force Academy and a master’s degree in Aeronautical and Astronautical Engineering from the Massachusetts Institute of Technology in Cambridge, Massachusetts. Hague was selected as an astronaut by NASA in 2013. An active-duty colonel in the U.S. Space Force, Hague completed a developmental rotation at the Defense Department and served as the Space Force’s director of test and evaluation from 2020 to 2022. In August 2022, Hague resumed duties at NASA, working on the Boeing Starliner Program until this flight assignment.
Follow @astrohague on X and Instagram.
Roscosmos cosmonaut Aleksandr Gorbunov will embark on his first trip to the space station as a mission specialist for Crew-9. Born in Zheleznogorsk, Kursk region, Russia, he studied engineering with qualifications in spacecraft and upper stages from the Moscow Aviation Institute. Gorbunov graduated from the military department with a specialty in operating and repairing aircraft, helicopters, and aircraft engines. Before his selection as a cosmonaut in 2018, he worked as an engineer for Rocket Space Corp. Energia and supported cargo spacecraft launches from the Baikonur Cosmodrome. Gorbunov will serve as a flight engineer during Expedition 71/72 aboard the space station.
Mission Overview
After liftoff, Dragon will accelerate to approximately 17,500 mph to dock with the space station.
Once in orbit, flight control teams from NASA’s Mission Control Center at the agency’s Johnson Space Center in Houston and the SpaceX mission control in Hawthorne, California, will monitor a series of automatic maneuvers that will guide Dragon to the forward-facing port of the station’s Harmony module. The spacecraft is designed to dock autonomously, but the crew can take control and pilot manually if necessary.
After docking, Expedition 71 will welcome Hague and Gorbunov inside the station and conduct several days of handover activities with the departing astronauts of NASA’s SpaceX Crew-8 mission. After a handover period, NASA astronauts Matthew Dominick, Michael Barratt, Jeanette Epps, and Roscosmos cosmonaut Alexander Grebenkin of Crew-8 will undock from the space station and splash down off the coast of Florida.
Crew-9 will conduct new scientific research to prepare for human exploration beyond low Earth orbit and benefit humanity on Earth. Experiments include the impact of flame behavior on Earth, studying cells and platelets during long-duration spaceflight, and a B vitamin that could reduce Spaceflight-Associated Neuro-ocular Syndrome. They’ll also work on experiments that benefit life on Earth, like studying the physics of supernova explosions and monitoring the effects of different moister treatments on plants grown aboard the station. These are just a few of over 200 scientific experiments and technology demonstrations taking place during their mission.
While aboard the orbiting laboratory, Crew-9 will welcome two Dragon spacecraft, including NASA’s SpaceX’s 31st commercial resupply services mission and NASA’s SpaceX Crew-10, and two Roscosmos-led cargo deliveries on Progress 90 and 91.
In February, Hague, Gorbunov, Wilmore, and Williams will climb aboard Dragon and autonomously undock, depart the space station, and re-enter Earth’s atmosphere. After splashdown off Florida’s coast, a SpaceX recovery vessel will pick up the spacecraft and crew, who then will be helicoptered back to shore.
Commercial crew missions enable NASA to maximize use of the space station, where astronauts have lived and worked continuously for more than 23 years testing technologies, performing research, and developing the skills needed to operate future commercial destinations in low Earth orbit, and explore farther from Earth. Research conducted on the space station provides benefits for people on Earth and paves the way for future long-duration trips to the Moon and beyond through NASA’s Artemis missions.
