Side-by-side images depict NASA's Curiosity rover (left) and a moon buggy driven during the Apollo 16 mission. Moon buggies were used during the Apollo missions to carry astronauts, lunar samples and equipment. During the Apollo 17 mission, that equipment included the Traverse Gravimeter Experiment (TGE), a special instrument for measuring gravity. Curiosity wasn't sent to Mars with gravimeters, but it does have accelerometers that are used to navigate the rover. A paper in Science published on Jan. 31, 2019, details how these sensors were repurposed to measure the gravitational pull of Mount Sharp, the mountain Curiosity has been climbing since 2014.

Under the direction of Marshall Space Flight Center (MSFC), the Lunar Roving Vehicle (LRV) was designed to allow Apollo astronauts a greater range of mobility during lunar exploration missions. During the development process, LRV prototype wheels underwent soil tests in building 4481 at Marshall Space Flight Center (MSFC). Pictured is the GM wheel design.

More than 500 students with 75 teams from around the world participated in the 31st year of NASA’s Human Exploration Rover Challenge (HERC) on April 11 and April 12, 2025, near NASA’s Marshall Space Flight Center in Huntsville, Alabama. Participating teams represented 35 colleges and universities, 38 high schools, and two middle schools from 20 states, Puerto Rico, and 16 other nations. NASA expanded the 2025 challenge to include a remote-control division - named Remote-Operated Vehicular Research - and invited middle school students to participate. Teams were awarded points based on navigating a half-mile obstacle course, conducting mission-specific task challenges, and completing multiple safety and design reviews with NASA engineers.
