Training months
The crew’s training lasted several months and included experimenting with high G-force in a centrifuge, a giant arm that rotates at high speed.
They also took parabolic flights to experience weightlessness for a few seconds and completed a high-altitude snow hike on Mount Rainier in the northwestern United States.
They spent time at the SpaceX base, although the flight itself will be completely autonomous. During the three days they are in orbit, they will be tested for sleep, heart rate, blood, and cognitive abilities.
Tests will be conducted before and after the mission to study the impact of the trip on their bodies. The idea is to accumulate data for future missions with private passengers.
The mission’s stated goal is to make space accessible to more people, although space travel remains for the moment only partially open to a privileged few. “In all of human history, fewer than 600 humans reached space,” Isaacman said.
“We are proud that our flight helps influence all those who travel after us.”
