An artist's illustration of an Earth-like planet. The search for planets that are similar to Earth is one of NASA's main goals. Many planets have already been discovered orbiting other stars, but so far only larger planets (the size of Jupiter or larger) have been found. New missions are being planned by NASA which will be able to detect smaller Earth-sized planets. Some of these missions will also try to detect signs of life on these planets by studying emissions in their atmospheres.

"The long-term survival of the human race is at risk as long as it is confined to a single planet. Sooner or later, disasters such as an asteroid collision or nuclear war could wipe us all out. But once we spread out into space and establish independent colonies, our future should be safe. There isn't anywhere like the Earth in the solar system, so we would have to go to another star."
-- Stephen Hawking, Physicist

"By 2025 we expect new spacecraft designed for long journeys to allow us to begin the first ever crewed missions beyond the Moon into deep space. So we’ll start by sending astronauts to an asteroid for the first time in history. 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 in see it."
--President Barack Obama, Cape Canaveral, Florida. Speech outlining his administration's space policy, 15 April 2010.

"We'll build new ships to carry man forward into the universe, to gain a new foothold on the Moon and to prepare for new journeys to the worlds beyond our own. . . . We do not know where this journey will end, yet we know this: human beings are headed into the cosmos."
-- President George W. Bush, speech at NASA headquarters, 14 January 2004

"All civilizations become either spacefaring or extinct."
-- Carl Sagan, Astronomer
