How does an astronaut prepare physically and mentally to launch into space? NASA astronaut Megan McArthur, who will take part in the SpaceX Crew-2 mission later this month, shares stellar life lessons on how to cultivate the resolve to do incredible things through preparation — and a dash of bravery. A rare glimpse at what it takes to literally shoot for the stars. (This virtual conversation, hosted by TEDWomen curator Pat Mitchell, was recorded in November 2020.)
