NASA chief: Mars is our mission Houston Chronicle

NASA’s emerging exploration plan will call for safely sending humans to Mars, possibly by the 2030s, and de-emphasize exploration of the moon, the agency’s leader said Tuesday.
“That is my personal vision,” NASA Administrator Charles Bolden said. “I am confident that, when I say humans on Mars is a goal for the nation, not just NASA, I’m saying that because I believe the president will back me up.”
Bolden cited appearances set before congressional committees on Feb. 24 and 25 as a deadline for creating the “beginnings of a plan” for human exploration.
At those hearings, Bolden said, he will be able only to give a range of dates for a Mars trip because scientific questions, such as mitigating radiation exposure and bone loss, remain unanswered.
But he confidently said the 2030s, even the early 2030s, were viable if given a reasonable and sustained budget.
