Even in the middle of the political storm, Wilmore and Williams continued to maintain an even keel at public appearances from orbit, casting no blame and insisting they supported NASA's decisions from the start.
NASA hired SpaceX and Boeing after the shuttle program ended, in order to have two competing U.S. companies for transporting astronauts to and from the space station until it's abandoned in 2030 and steered to a fiery reentry. By then, it will have been up there more than three decades; the plan is to replace it with privately run stations so NASA can focus on moon and Mars expeditions.
Both retired Navy captains, Wilmore and Williams stressed they didn't mind spending more time in space — a prolonged deployment reminiscent of their military days. But they acknowledged it was tough on their families.
