As we visit Mars multiple times, we will build up infrastructure on the surface to expand the capabilities and reach of humans on Mars.
My key aim is to get man on the surface of Mars by the mid-2030s.
As a card-carrying space nerd and NASA's chief scientist, I love space movies, from 'Star Trek' to 'Star Wars' to my all-time favorite - 'The Dish', an Australian comedy that celebrates that first moment when Neil Armstrong stepped down onto the surface of our moon.
Mars was this water-based planet, and we know there was stable water on the surface for a long time, which is critical for life having a chance to develop.
Prior to Magellan, due to the fact that we knew it was so hot on Venus, we thought that the rocks at the surface would behave more plastically, more like Silly Putty than like solid rock in the way that we think of it, like the rocks that I'm sitting on.
