NASA has recommitted itself to landing humans on Mars by 2035, but
has admitted that this is a project that will require the world to
work together. NASA's chief scientist Ellen Stofan gave a talk to the
Royal Institution in London a fortnight ago, and video of the talk

do on their own," Stofan said. "It's something that
humanity is going to do together."
Stofan sees a Mars mission as a crucial part of the quest to
answer the three questions she says turn up repeatedly in NASA's
goals: “Are we alone, how did we get here and how does the universe
work.” Mars is particularly important for answering the other two,
she argued, although she also talked about the potential for life on
Europa and
Enceladus. Read more.
