Canada aims to provide medical technologies for deep space exploration

Transcript¹

Twenty teams in Canada received small grants to develop portable medical tools that could be used on long interplanetary space flights. They could also be useful in remote parts of Canada.

A MARTINEZ, HOST:

Canada plays a big part in the U.S. space program. The Canadarm, for instance, is critical hardware on the International Space Station. Now Canada is angling to provide medical tech for deep space exploration. NPR's Joe Palca has more.

JOE PALCA, BYLINE²: To get to Mars, astronauts will have to spend months in space. A major challenge will be making sure they stay healthy during the trip. Lightweight, remotely operable medical equipment will be essential. To develop that equipment, the Canadian Space Agency started the Deep Space Healthcare Challenge. Annie Martin runs the challenge. She says there weren't any restrictions³ on what people could propose.

ANNIE MARTIN: We didn't want to limit any potential great ideas.

PALCA: While it's true Canada wants a role in space exploration, the same technologies could play a role in providing health care to people in that country's many small and isolated⁴ communities.

MARTIN: We're looking for a solution that could first address remote health care needs on Earth.

PALCA: Martin says they got about a hundred entries for the health care challenge, and there are a variety of intriguing⁵ ideas - clothing that can detect problems with muscles or joints⁶, patches that can provide an early alert about heart problems. And then there's Gordon Sarty's idea.

GORDON SARTY: And the idea is simple - put MRI into space.

PALCA: MRIs are used to provide detailed⁷ images of what's going on inside someone's body. Most MRI machines weigh many tons. Sarty has been working on MRIs at the University of Saskatchewan for years, and he thinks he can make a pint-sized version.

SARTY: A couple hundred kilograms max.

PALCA: While not as versatile⁸ as its heavier cousins, Sarty says the MRI he wants to build will still be useful for spotting medical problems.

SARTY: Tumors - you can still see tumors. Maybe not as small of a tumor⁹ as you could with a larger MRI, but those kinds of capabilities¹⁰ are all still there.

PALCA: Of course, there's still the issue of what to do about a tumor if you find one. There are no mini clinics or emergency rooms on the way to Mars. Canada is hoping to be part of the creative thinking it will take to solve that problem as well.
