Life in the Universe
Could humans be the only intelligent beings in all the vastness of the universe? Or are we just one humble race, a member of a vast intergalactic fraternity of advanced civilizations? SETI, the Search for Extraterrestrial Intelligence, is the scientific quest to answer these great unknowns. As of now all we have are questions, but we know the answers, when they come, could transform our world. Since the day it was formed in 1980, The Planetary Society has been there to support the search.
And what about other life? Is there -- or was there ever -- anything else alive in our solar system? Did microbes once spring to life in oases on early Mars, or around the undersea volcanic vents of Europa or Enceladus? Could life have originated on Mars and been transported to Earth? We've never detected evidence for anything living elsewhere than our own fragile planet. Are we alone?
The Planetary Society Optical SETI Telescope in Harvard, Massachusetts just got a major upgrade of its electronics. The telescope, which has been operating the only all-sky optical SETI survey since its opening in 2006, is run by Harvard University Professor Paul Horowitz and his team. The telescope scans the sky every clear night with a 72-inch primary mirror, looking for laser pulses as short as one billionth of a second that could be transmitted by distant extraterrestrials. When observing, it has been able to process 1 terabit (trillion bits) of data every second, that’s as much as in all the books in print every second.

We are super excited that the Planetary Society’s Phobos LIFE (Living Interplanetary Flight Experiment) is about ready to launch to Mars’ moon Phobos and back. We have been working for years preparing this unique test of the effects of long term exposure to deep space on a wide variety of life.

In the middle of the night on June 1, 2011, millions of passengers returned safely to Earth as part of the great conclusion to space shuttle Endeavour's last flight, STS-134. Many of those millions of passengers were part of the Planetary Society's Shuttle LIFE experiment. Five different kinds of creatures from all three domains of life are part of Shuttle LIFE.
