As it flew up toward the International Space Station last summer, the Starliner spacecraft lost four thrusters. A NASA astronaut, Butch Wilmore, had to take manual control of the vehicle. But as its thrusters failed, Wilmore lost the ability to move Starliner in the direction he wanted to go.
He and his fellow astronaut, Suni Williams, knew where they wanted to go. Starliner had flown to within a stone’s throw of the space station, a safe harbor if only they could reach it. But already, the failure of so many thrusters violated the mission’s flight rules. In such an instance, they were supposed to turn around and come back to Earth. Approaching the station was deemed too risky for Wilmore and Williams, aboard Starliner, as well as the astronauts on the $100 billion space station.
But what if it was not safe to come home, either?
