But usually they have some sense of what’s remotely possible, and of what they’ve asked their space agency to do. In the spring of 2017, President Trump signed a significant piece of legislation about the future of NASA. The bill, among other things, reaffirmed a top priority for the American space program: Sending humans to Mars by the 2030s.
