After three years of engineering work, Astrobotic’s CubeRover is on its way to NASA’s Kennedy Space Center in Florida. The CubeRover is designed to provide an affordable mobile outlet for scientific instruments and other payloads to operate on the surface of the Moon. This occasion marks the first time Astrobotic’s Planetary Mobility department has delivered rover hardware to an outside entity.
Named for its modular, scalable design, the CubeRover was co-developed with Carnegie Mellon University, with input from a NASA team at Kennedy, and marks the completion of work on NASA’s $750,000 Small Business Innovation Research (SBIR) Phase 2 contract to develop a lightweight rover with flight characteristics.
Astrobotic has since refined and commercialized the CubeRover product line with the goal of supporting mobility as a service with a variety of diverse payloads, making lunar access easier for smaller tech demonstrations and scientific investigations. The rover is also designed to be integrated onto multiple lunar landers for voyages to the Moon, facilitating its inclusion on a wide variety of future space missions.
Designing the compact CubeRover presented an array of engineering challenges for the Astrobotic and Carnegie Mellon teams. Among many concerns, the teams were tasked with regulating the rover’s temperature in extreme climate fluctuations, keeping its mass minimal, and ensuring the rover maintained optimum mobility for instruments operating on the rover. The teams created a robust thermal design able to endure temperatures ranging from space (-455ºF) to the lunar surface (260ºF). The result is the lightest commercial planetary rover ever created. The CubeRover was also outfitted with a calibrated camera used to orient itself relative to known objects on the lunar surface, such as Astrobotic’s Peregrine lander. The ability for the rover’s operation team to recognize its position on the Moon augments the value of the data, allowing payload customers to make informed decisions about where to travel next.
“Because our CubeRover is so light — in the four kilogram range — it dramatically reduces flight cost, making the Moon more accessible to more customers,“ says Mike Provenzano, Astrobotic’s director of Planetary Mobility. ““We’re also including industry standard interfaces throughout the rover to simplify the payload integration process.”
