The budget also eliminated the chance of a Europa lander. The budget and encouragement was made with the intention of getting a man to Mars. Doing that may seem impressive, but there's so much more science that can be achieved through cheaper unmanned exploration of other parts of the Solar System. Mars is Trump's vanity project. He wants to be for Mars what Kennedy is for the Moon.
