How spaceflight changed my perspectives on our planet and humanity
When you spend a total of 204 days and 18 hours in space, and make 3170 orbits of the planet during your missions, you get a new perspective on the planet we inhabit. Canadian astronaut Dr. Robert Thirsk reflects powerfully on how his viewpoint changed as his missions progressed, and the priorities that this orbital perspective sets for our survival as a species.
As a member of the Canadian Space Agency’s astronaut corps, Dr. Robert Thirsk has spent a combined 205 days in space, observing our world and its signals and noise from a unique vantage point. First flying in 1996 for 17 days aboard the space shuttle Columbia as part of the Life and Microgravity Spacelab Mission, he returned in 2009 with a 188-day mission on the International Space Station to perform robotic operations and station maintenance.
