CubeRover

CubeRover is a class of planetary rover with a standardized modular format meant to accelerate the pace of space exploration. The idea is equivalent to that of the successful CubeSat format, with standardized off-the-shelf components and architecture to assemble small units that will be all compatible, modular, and inexpensive.[1]

The rover class concept is being developed by Astrobotic Technology in partnership with Carnegie Mellon University, and it is partly funded by NASA awards.[1] The Principal Investigator of the program is Andrew Horchler. In June 2019, Astrobotic Technology was awarded US$79.5 million to carry 14 payloads to the moon, including a CubeRover, no earlier than July 2021;[2] this mission is currently scheduled to launch in 2022.[3] This would make Carnegie Mellon University the first university in the world to fully develop a lunar rover and the first American entity to successfully pilot an unmanned lunar vehicle.[2]

Overview[edit]

Concept[edit]

The idea is to create a practical modular concept similar that used for CubeSats and apply it to rovers, effectively creating a new standardized architecture of small modular planetary rovers with compatible parts, systems, and even instruments so that each mission can be easily tailored to its objectives.[1][4][5] The rovers are expendable and do not use solar arrays for electrical power, depending solely on non-rechargeable batteries. This allows it to be lighter, have a larger cooling radiator panel for electronics, and have a simpler avionics design.[6]

The CubeRover program intends that standardizing small rover design with a common architecture will open access to planetary bodies for companies, governments, and universities around the world at a low cost, while increasing functionality, just as the CubeSat has in Earth orbit.[4] This would motivate other members of the space exploration community to develop new systems and instruments that are all compatible with the CubeRover's architecture.[1][4]

In May 2017 Astrobotic Technology, in partnership with Carnegie Mellon University, were selected by NASA's Small Business Innovation Research (SBIR) to receive a $125,000 award[10] to develop a small lunar rover architecture capable of performing small-scale science and exploration on the Moon and other planetary surfaces. During Phase I, the team built a 2-kg rover and performed engineering studies to determine the architecture of a novel chassis, power, computing systems, software and navigation techniques.

In March 2018, the team was awarded funds to move on to Phase II,[1][4] and under this agreement, Astrobotic will produce a flight-ready rover with a mass of approximately 2 kg (4.4 lb) that will fly on Astrobotic's Peregrine lunar lander to the Moon[2] in 2022.

In future missions, CubeRovers may be designed to take advantage of lander-based systems to shelter for the cold lunar night, that lasts for 14 Earth days.[4] Similarly, future larger CubeRovers may be able to incorporate thermal insulation and systems qualified for ultra-low temperatures.[4]

A spinoff company was created in 2018, called CubeRover, and it is based in Luxembourg City, Luxembourg.[11] Its president is Mike Provenzano. The company has support from Luxemburg and it is expected to collaborate with local universities and companies.[12][13] It is hoped that it will become a hub for small planetary rover design, manufacture, and assembly, as well as a shop.

The first derivative of a CubeRover, a spinoff rover called Iris developed by CMU students, is planned to be deployed on the Moon on board Astrobotic's Peregrine lander[14] in 2022.
