Has NASA 'RESOLVE'd' on Canadian lunar rover?

Neptec Design Group of Ottawa is the front-runner to build the next moon rover — a traveling robot that will hunt for water on an unmanned NASA mission in 2017. NASA has asked the Canadian Space Agency specifically for Neptec’s rover, called Artemis Jr., said Mike Kearns, president of space exploration with the Ottawa aerospace engineering firm.

It has chosen a Canadian drill and Canadian avionics, too.

“One of the missions on that path is called RESOLVE, renamed by some people now as the Lunar Prospector Mission,” Kearns said.“NASA, for funding reasons, has asked CSA to provide the rover and the drill. And they actually asked for our Neptec rover ... and for the drill that is made by a company called Deltion.” (Deltion Innovations of Sudbury took over the design that originated with NORCAT. Its drill developed out of Canadian mining technology.)

What sealed NASA’s interest was a test drive of the rover prototype on the side of a Hawaiian volcano, in 2012. Chosen to simulate the harsh landscape of the moon and Mars, it provided a place for Artemis Jr. to drive, pivot and steer past obstacles using its vision system and navigation software. It passed nine days of tests.It’s called “Jr.” because this is a scaled-down version of a Neptec rover designed to carry astronauts, called Artemis.

Searching for water in space is vital. Not only can astronauts drink it, but it can be broken down into oxygen and hydrogen, both used in rocket propellant. Artemis Jr. could also search for methane.Neptec hopes the 2017 date will resonate with politicians who want some flag-waving in Canada’s 150th year.

“The question that always comes up is: That’s very nice but what’s the financial benefit? What’s the return to the taxpayers. And the answer is that ... for every dollar that CSA gives us, we end up with $10, mostly in export sales. We sell those products around the world.”

While the Canadian Space Agency can open the bidding to include MDA, the CANADARM builders, Kearns says NASA’s preference gives his company’s Artemis Jr. rover a strong chance. MDA officials weren’t available for comment Monday.

NASA is publicly leaning toward the Neptec team. In a description of the mission it writes: “RESOLVE is not just a NASA effort; the Canadian Space Agency provided Artemis Jr., which is the rover for the payload; the onboard drill and sample transfer system; as well as avionics microprocessors.”

Artemis Jr. is actually the product of a group of Canadian companies: Ontario Drive and Gear, from New Hamburg, Ont.; ComDev and Neptec from Ottawa; Deltion; and NGC from Sherbrooke.

The four-wheeled rover can pivot on one spot, moving the right wheels forward and the left ones in reverse. It has coarse metal treads for traction, and a solar panel on top.

It’s designed for NASA’s Regolith & Environment Science and Oxygen & Lunar Volatile Extraction (RESOLVE) project, which involves heating the “regolith” (loose minerals on the moon’s surface) to extract gas.
