After all, Curiosity could get some much needed company!

Elon Musk and his private spaceflight company SpaceX recently outlined their plan to make space travel to Mars an affordable reality—just $500,000 for a one-way ticket to the Red Planet. To shuttle people to Mars (within the next decade if ambitious goals can be met) SpaceX is working on a carbon fiber fuel tank for a massive 400-foot-tall reusable rocket that only exists on the drawing board at this point.

But getting people to Mars is only half the battle. Making sure that they can survive, possibly for decades, is a whole different challenge. SpaceX might be the perfect organization to launch people to the Red Planet on massive rockets, but they are going to need some help from NASA to build a sustainable colony, which is its proposed goal.

Fortunately, NASA has been quietly working on ways to harvest Martian resources for some years—a necessary step to ultimately realize a self-sustained Martian colony. In April 2016, NASA published a scientific and technical information (STI) paper titled "Frontier In-Situ Resource Utilization for Enabling Sustained Human Presence on Mars." The paper outlines various ways that minerals, water, and atmospheric gasses could be harvested and used to manufacture plastics, rocket propellants, habitat-heating fuels, and even more complicated materials like fiberglass—all with materials that are already on Mars.

Which is where the Regolith Advanced Surface Systems Operations Robot (RASSOR) comes in (see video above). The robot, which could be affixed to a rover or made into a rover itself, uses a rotating digging device to scoop up soils that could then be used for resource extraction. As NASA writes on its website, the RASSOR's "design incorporates net-zero reaction force, thus allowing it to load, haul, and dump space regolith under extremely low gravity conditions with high reliability."

The bot in the video above is actually the RASSOR 2.0, a scaled-up prototype of the original 2013 design. If we are going to build a self-sustained colony on Mars in the foreseeable future, the first step will be sending a host of robots like RASSOR to the Red Planet to get to work building our Martian home for us. As the NASA STI paper states regarding a Martian colony: "The crew is there to explore, and to colonize, not maintain and repair. Any time spent on 'living there' and 'housekeeping' should be minimized to an oversight role of robotic automated tasks."
