'Definite Evidence' Of Alien Life Within 20-30 Years, NASA Chief Scientist Says


There will be "strong indications" of alien life within a decade and "definite evidence" of it within 20 to 30 years, NASA's chief scientist has said.
"We know where to look. We know how to look," Ellen Stofan said during a panel discussion Tuesday on NASA's search for alien life and habitable worlds. "In most cases, we have the technology, and we're on a path to implementing it."
But she was quick to add: "We are not talking about little green men. We are talking about little microbes."
Her colleague John Grunsfeld, a former astronaut and associate administrator for the agency's Science Mission Directorate, agreed.
"I think we're one generation away in our solar system, whether it's on an icy moon or on Mars, and one generation [away] on a planet around a nearby star," Grunsfeld said at the same discussion.
Jeffery Newmark, NASA's interim director of heliophysics, added: "It's definitely not an if, it's a when." npr
