"Obama did not predict a Mars landing soon. But he said that by 2025, the nation would have a new spacecraft "designed for long journeys to allow us to begin the first-ever crewed missions beyond the moon into deep space."
"We'll start by sending astronauts to an asteroid for the first time in history," he said. "By the mid-2030s, I believe we can send humans to orbit Mars and return them safely to Earth. And a landing on Mars will follow. And I expect to be around to see it."
 
Can a life-support system for Mars voyagers be developed in a quarter century? 
What if Obama means he plans to live a very long life-- so that "And I expect to be around to see it" could mean more than a century from now? 
 
It's not what people say, it's what they don't say.
