Students from Universidad Católica Boliviana “San Pablo” compete during NASA’s 2024 Human Exploration Rover Challenge. The 2025 competition takes place Friday and Saturday, April 11-12, 2025, at the U.S. Space & Rocket Center’s Aviation Challenge course in Huntsville, Alabama. NASA NASA’s annual Human Exploration Rover Challenge returns Friday, April 11, and Saturday, April 12, with student teams competing at the U.S. Space & Rocket Center’s Aviation Challenge course near the agency’s Marshall Space Flight Center in Huntsville, Alabama.
Media are invited to watch as hundreds of students from around the world attempt to navigate a complex obstacle course by piloting a vehicle of their own design and production. Media interested in attending or setting up interviews should contact Taylor Goodwin in the Marshall Office of Communications at 938-210-2891 no later than 2 p.m. Thursday, April 10.
In addition to the traditional human-powered rover division, this year’s competition expands the challenge to include a remote-control division. The 2025 HERC Handbook includes guidelines for the new remote-control division and updates for the human-powered division.
Participating teams represent 35 colleges and universities, 38 high schools, and two middle schools from 20 states, Puerto Rico, and 16 other nations.
The event is free and open to the public, with rover excursions from 7:30 a.m. to 3 p.m. CDT each day, or until the last rover completes the obstacle course.
Following the competition, NASA will host an in-person awards ceremony Saturday, April 12, at 5:30 p.m. inside the Space Camp Operations Center at the U.S. Space & Rocket Center. NASA and industry sponsors will present multiple awards highlighting team successes throughout the past eight-months-long engineering design project, including awards for best rover design, best pit crew, best social media presence, and many other accomplishments.
About the Challenge
Recognized as NASA’s leading international student challenge, the Human Exploration Rover Challenge aims to put competitors in the mindset of NASA’s Artemis campaign. Teams pitch an engineering design for a lunar rover which simulates astronauts exploring the lunar surface while overcoming various obstacles. Eligible teams compete to be among the top three finishers in their divisions, and to win multiple awards, including best vehicle design, best rookie team, and more.
The annual challenge draws hundreds of students from around the world and reflects the goals of NASA’s Artemis campaign, which will establish the first long-term presence on the Moon and pave the way for eventual missions to Mars.
The event was launched in 1994 as the NASA Great Moonbuggy Race – a collegiate competition to commemorate the 25th anniversary of the Apollo 11 lunar landing. It expanded in 1996 to include high school teams, evolving again in 2014 into the NASA Human Exploration Rover Challenge. Since its inception, more than 15,000 students have participated – with many former students now working in the aerospace industry, including with NASA.
The Human Exploration Rover Challenge is managed by NASA Marshall’s Southeast Regional Office of STEM Engagement and is one of eight Artemis Student Challenges. NASA’s Office of STEM Engagement uses challenges and competitions to further the agency’s goal of encouraging students to pursue degrees and careers in science, technology, engineering, and mathematics.

A group of attendees of the joint NASA-USGS workshop, Planetary Subsurface Exploration for Science and Resources, gathers for a photo at NASA’s Ames Research Center on Feb. 11, 2025. Workshop participants discussed observations, technologies, and operations needed to support new economies for terrestrial and off-world resources, including critical minerals.NASA/Brandon Torres Navarrete NASA and the U.S. Geological Survey (USGS) welcomed a community of government, industry, and international partners to explore current technology needs around natural resources – both on Earth and “off world.” During a workshop held in February at NASA’s Ames Research Center in California’s Silicon Valley, participants discussed technologies that will improve the ability to detect, assess, and develop resources, such as critical minerals and water ice to be found on our Moon, other planets and their moons, and asteroids.
More than 300 attendees, taking part in person and virtually, worked to define the elements needed to find and map resources beyond Earth to support the growing space economy. These include sensors to image the subsurface of planetary bodies, new platforms for cost-effective operations, and technologies that enable new concepts of operation for these systems.
Scientific studies and measurements of off-world sites will be key to detecting and characterizing resources of interest, creating an important synergy with technology goals and helping to answer fundamental science questions as well.
The workshop was the third in a series called Planetary Subsurface Exploration for Science and Resources. By leveraging the expertise gained from decades of resource exploration on this planet and that of the space technology and space mission communities, NASA and USGS aim to spark collaboration across industry, government, and academia to develop new concepts and technologies.
Participants in the NASA-USGS off-world resources workshop take part in a panel review of technology opportunities, Feb. 13, 2025, at NASA’s Ames Research Center. The panelists were Dave Alfano, chief of the Intelligent Systems Division at NASA’s Ames Research Center in California’s Silicon Valley (left); Rob Mueller, a senior technologist and principal investigator in the Exploration Research and Technology Programs Directorate at NASA’s Kennedy Space Center in Florida; Christine Stewart, CEO at Austmine Limited in Australia; Gerald Sanders, in-situ resource utilization system capability lead for NASA’s Space Technology Mission Directorate based at NASA’s Johnson Space Center in Houston; and Jonathon Ralston, Integrated Mining Research Team lead at Australia’s Commonwealth Scientific and Industrial Research Organisation.

Intuitive Machines’ IM-2 captured an image March 6, 2025, after landing in a crater from the Moon’s South Pole. The lunar lander is on its side about 820 feet from the intended landing site, Mons Mouton. In the center of the image between the two lander legs is the Polar Resources Ice Mining Experiment 1 suite, which shows the drill deployed.Credit: Intuitive Machines Shortly after touching down inside a crater on the Moon, carrying NASA technology and science on its IM-2 mission, Intuitive Machines collected some data for the agency before calling an early end of mission at 12:15 a.m. CST Friday.
As part of the company’s second Moon delivery for NASA under the agency’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign, the IM-2 mission included a drill to bring lunar soil to the surface and a mass spectrometer to look for the presence of volatiles, or gases, that could one day help provide fuel or breathable oxygen to future Artemis explorers.
Planned to land at Mons Mouton, IM-2 touched down at approximately 11:30 a.m. March 6, more than 1,300 feet (400 meters) from its intended landing site. Intuitive Machines said images collected later confirmed the lander was on its side, preventing it from fully operating the drill and other instruments before its batteries were depleted.
The IM-2 mission landed closer to the lunar South Pole than any previous lander.
“Our targeted landing site near the lunar South Pole is one of the most scientifically interesting, and geographically challenging locations, on the Moon,” said Nicky Fox, associate administrator for science at NASA Headquarters in Washington. “Each success and setback are opportunities to learn and grow, and we will use this lesson to propel our efforts to advance science, exploration, and commercial development as we get ready for human exploration of Mars.”
The Nova-C lander, named Athena, captured and transmitted images of the landing site before activating the technology and science instruments. Among the data collected, NASA’s PRIME-1 (Polar Resources Ice Mining Experiment 1) suite, which includes the lunar drill known as TRIDENT (The Regolith and Ice Drill for Exploring New Terrain), successfully demonstrated the hardware’s full range of motion in the harsh environment of space. The Mass Spectrometer Observing Lunar Operations (MSOLO) as part of the PRIME-1 suite of instruments, detected elements likely due to the gases emitted from the lander’s propulsion system.
“While this mission didn’t achieve all of its objectives for NASA, the work that went into the payload development is already informing other agency and commercial efforts,” said Clayton Turner, associate administrator for space technology, NASA Headquarters. “As we continue developing new technologies to support exploration of the Moon and Mars, testing technologies in-situ is crucial to informing future missions. The CLPS initiative remains an instrumental method for achieving this.”
Despite the lander’s configuration, Intuitive Machines, which was responsible for launch, delivery, and surface operations under its CLPS contract, was able to complete some instrument checkouts and collect 250 megabytes of data for NASA.
“Empowering American companies to deliver science and tech to the Moon on behalf of NASA both produces scientific results and continues development of a lunar economy,” said Joel Kearns, deputy associate administrator for Exploration in the Science Mission Directorate at NASA Headquarters. “While we’re disappointed in the outcome of the IM-2 mission, we remain committed to supporting our commercial vendors as they navigate the very difficult task of landing and operating on the Moon.”
NASA’s Laser Retroreflector Array, a passive instrument meant to provide a reference point on the lunar surface and does not power on, will remain affixed to the top deck of the lander. Although Intuitive Machines’ Nova-C Hopper and Nokia’s 4G/LTE Tipping Point technologies, funded in part by NASA, were only able to complete some objectives, they provided insight into maturing technologies ready for infusion into a commercial space application including some checkouts in flight and on the surface.
Intuitive Machines’ IM-2 mission launched at 6:16 p.m., Feb. 26, aboard a SpaceX Falcon 9 rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida.
Intuitive Machines has two more deliveries on the books for NASA in the future, with its IM-3 mission slated for 2026, and IM-4 mission in 2027.
To date, five vendors have been awarded a total of 11 lunar deliveries under CLPS and are sending more than 50 instruments to various locations on the Moon, including the Moon’s far side and South Pole region. CLPS contracts are indefinite-delivery/indefinite-quantity contracts with a cumulative maximum contract value of $2.6 billion through 2028.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
An artist’s concept depicts one of NASA’s Voyager probes. The twin spacecraft launched in 1977.NASA/JPL-Caltech The farthest-flung human-made objects will be able to take their science-gathering even farther, thanks to these energy-conserving measures.
Mission engineers at NASA’s Jet Propulsion Laboratory in Southern California turned off the cosmic ray subsystem experiment aboard Voyager 1 on Feb. 25 and will shut off Voyager 2’s low-energy charged particle instrument on March 24. Three science instruments will continue to operate on each spacecraft. The moves are part of an ongoing effort to manage the gradually diminishing power supply of the twin probes.
Launched in 1977, Voyagers 1 and 2 rely on a radioisotope power system that generates electricity from the heat of decaying plutonium. Both lose about 4 watts of power each year.
“The Voyagers have been deep space rock stars since launch, and we want to keep it that way as long as possible,” said Suzanne Dodd, Voyager project manager at JPL. “But electrical power is running low. If we don’t turn off an instrument on each Voyager now, they would probably have only a few more months of power before we would need to declare end of mission.”
The two spacecraft carry identical sets of 10 science instruments. Some of the instruments, geared toward collecting data during planetary flybys, were turned off after both spacecraft completed their exploration of the solar system’s gas giants.
The instruments that remained powered on well beyond the last planetary flyby were those the science team considered important for studying the solar system’s heliosphere, a protective bubble of solar wind and magnetic fields created by the Sun, and interstellar space, the region outside the heliosphere. Voyager 1 reached the edge of the heliosphere and the beginning of interstellar space in 2012; Voyager 2 reached the boundary in 2018. No other human-made spacecraft has operated in interstellar space.
Last October, to conserve energy, the project turned off Voyager 2’s plasma science instrument, which measures the amount of plasma — electrically charged atoms — and the direction it is flowing. The instrument had collected only limited data in recent years due to its orientation relative to the direction that plasma flows in interstellar space. Voyager 1’s plasma science instrument had been turned off years ago because of degraded performance.
Interstellar Science Legacy
The cosmic ray subsystem that was shut down on Voyager 1 last week is a suite of three telescopes designed to study cosmic rays, including protons from the galaxy and the Sun, by measuring their energy and flux. Data from those telescopes helped the Voyager science team determine when and where Voyager 1 exited the heliosphere.
Scheduled for deactivation later this month, Voyager 2’s low-energy charged particle instrument measures the various ions, electrons, and cosmic rays originating from our solar system and galaxy. The instrument consists of two subsystems: the low-energy particle telescope for broader energy measurements, and the low-energy magnetospheric particle analyzer for more focused magnetospheric studies.
Both systems use a rotating platform so that the field of view is 360 degrees, and the platform is powered by a stepper motor that provides a 15.7-watt pulse every 192 seconds. The motor was tested to 500,000 steps — enough to guarantee continuous operation through the mission’s encounters with Saturn, which occurred in August 1980 for Voyager 2. By the time it is deactivated on Voyager 2, the motor will have completed more than 8.5 million steps.
“The Voyager spacecraft have far surpassed their original mission to study the outer planets,” said Patrick Koehn, Voyager program scientist at NASA Headquarters in Washington. “Every bit of additional data we have gathered since then is not only valuable bonus science for heliophysics, but also a testament to the exemplary engineering that has gone into the Voyagers — starting nearly 50 years ago and continuing to this day.”
Addition Through Subtraction
Mission engineers have taken steps to avoid turning off science instruments for as long as possible because the science data collected by the twin Voyager probes is unique. With these two instruments turned off, the Voyagers should have enough power to operate for about a year before the team needs to shut off another instrument on both spacecraft.
In the meantime, Voyager 1 will continue to operate its magnetometer and plasma wave subsystem. The spacecraft’s low-energy charged particle instrument will operate through the remainder of 2025 but will be shut off next year.
Voyager 2 will continue to operate its magnetic field and plasma wave instruments for the foreseeable future. Its cosmic ray subsystem is scheduled to be shut off in 2026.
With the implementation of this power conservation plan, engineers believe the two probes could have enough electricity to continue operating with at least one science instrument into the 2030s. But they are also mindful that the Voyagers have been weathering deep space for 47 years and that unforeseen challenges could shorten that timeline.
Long Distance
Voyager 1 and Voyager 2 remain the most distant human-made objects ever built. Voyager 1 is more than 15 billion miles (25 billion kilometers) away. Voyager 2 is over 13 billion miles (21 billion kilometers) from Earth.
In fact, due to this distance, it takes over 23 hours to get a radio signal from Earth to Voyager 1, and 19½ hours to Voyager 2.
“Every minute of every day, the Voyagers explore a region where no spacecraft has gone before,” said Linda Spilker, Voyager project scientist at JPL. “That also means every day could be our last. But that day could also bring another interstellar revelation. So, we’re pulling out all the stops, doing what we can to make sure Voyagers 1 and 2 continue their trailblazing for the maximum time possible.”
