Last Monday Stephen Hawking gave a speech at an event commemorating the 50th anniversary of NASA. Hawking has long been a proponent of the value of humans exploring space, and again called for a determined effort by humans to colonize the moon and Mars. He put special emphasis on putting humans into space, and not relying solely on robotic explorers, which is largely driven by the survival of humans, longer term, and is an insurance policy against war, catastrophe, and disaster here on Earth. A great quote from the speech:

“Robotic missions are much cheaper and may provide more scientific information, but they don’t catch the public imagination in the same way, and they don’t spread the human race into space, which I’m arguing should be our long-term strategy. If the human race is to continue for another million years, we will have to boldly go where no one has gone before.”

With regards to life on other planets, Hawking offered three possibilities: that life in the universe, of any type, is rare; that simple forms of life may be common, but intelligent forms of life rare; or that intelligent life typically destroys itself. He went on to say:

“Personally, I favor the second possibility – that primitive life is relatively common, but that intelligent life is very rare. Some would say it has yet to occur on Earth.”
