GORMLEY - TIM HALTIGIN - FEBRUARY 18

Today is a big day for space exploration, as NASA's Perseverance rover is scheduled to touch down on Mars. While the mission is American, a number of Canadians are involved, including Tim Haltigin with the Canadian Space Agency. Haltigin helped design the program to study samples once they're returned to Earth, and he joins Gormley to tell us why today's landing is such a major milestone in our exploration of the Red Planet.
