What would it take to get humans to Mars?
For the last seven months, NASA's rover 'Curiosity' has crawled all over the planet's dusty red Gale Crater.
As it explores, the rover has sent back all sorts of information to Earth for further investigation.
Most recently, a report of a rock sample collected by Curiosity shows that, yes, ancient Mars could have supported living microbes.
But let's go one step further. What would it take for human beings to get to Mars?
Ben Longmier is an Assistant Professor of Aerospace Engineering at the University of Michigan College of Engineering and researches electric propulsion, spacecraft design and basic plasma physics.
Michigan Radio's Cynthia Canty spoke with Longmier about the challenges and possibilities of getting humans on Mars.
