NASA looks to students to find water on Mars

A new sort of space race is upon us, and this time the finish line is on Mars.

With NASA planning manned-missions to the red planet in the 2030s, and Elon Musk envisioning a million-person Martian city, the goal of becoming a multi-planetary species feels within reach. But first, we need a plan for staying hydrated.

Scientists have confirmed that there appears to be water on Mars. The challenge is that most of it is stored as ice deep beneath the planetโ€™s dusty surface, and accessing it requires drilling through a thick layer of dirt and melting the ice.

Daniel McGann, E/CISโ€™20, knows all about the quest for water on Mars. Heโ€™s leading a team of Northeastern students selected as finalists for the 2018 NASA RASC-AL Mars Ice Challenge, in which groups are competing to build the best robotic water-extraction device. The Northeastern teamโ€™s proposal was one of ten chosen from a pool of 50 submissions from universities all over the country.

โ€œThe end goal of this is to extract usable water, not dirty water or brown water, but clean, usable, hypothetically drinkable water from this environment,โ€ McGann said.

His teammates include Elisa Danthinne, Eโ€™21; Emmy Kelly, Eโ€™20; Rashad Khan Eโ€™21; Patrick Moore, E โ€™21; Andrew Panasyuk, E/Sโ€™20; Grace Peck, E/Sโ€™20; Fizzah Shaikh, Eโ€™21; Tucker Spencer-Wallace, Eโ€™21; and Ben Zinser Eโ€™21. Taskin Padir, associate professor of electrical and computer engineering at Northeastern, serves as the teamโ€™s faculty advisor.

The device the Northeastern team is building will be a fully autonomous robotic system. In the studentsโ€™ proposed design, the robot is shaped like a large 3-D printer that includes a drill and an extractor. Both are attached to a positioning system within a metal frame. The drill will make a hole for the extractor, which is outfitted with a heating element, to glide down through a layer of dirt and into the ice. Once it has penetrated the ice, the extractor moves around, melting as it goes and pumping water back to the surface.

โ€œWe want to extract as much ice as possible,โ€ McGann said. โ€œWe determined the best way to do that would be to drill as few holes as we can and expand our reach once we have actually accessed the ice.โ€ The competition will test each device on a simulated Martian surface of dirt and an ice block half a meter thick.

As finalists, the Northeastern team must construct its prototype, produce a technical paper, and give a poster presentation. In June, the team will travel to the NASA Langley Research Center in Hampton, Virginia, to compete. NASA has awarded them $10,000 to build the device.

โ€œWhat NASA really looks for with a small investment is to have a tap into the minds of the younger generations,โ€ said Padir. โ€œOur team had the perseverance from day one.โ€

For McGann, that motivation comes from an inherent love of the cosmos. โ€œPersonally, Iโ€™m just crazy interested in space,โ€ he said. โ€œI think Iโ€™ve wanted to be an astronaut since I was about 2 and still do, so really any opportunity I have to work with other people who are interested in space, anything to do with exploration, I canโ€™t get enough of it. I know itโ€™s true among a lot of people on the team. Weโ€™re all kind of space nerds.โ€
