The inventor of the Drake Equation, Frank Drake just did a Q&A

The inventor of the Drake Equation just did a Q&A I highly recommend checking out. He talks about his thoughts on Extraterrestrial life and our current technology.

In addition to inventing the Drake Equation Frank Drake also helped design the Pioneer Plaque and The Golden Record.

The Drake Equation is used to estimate the number of communicating civilizations in the cosmos, or more simply put, the odds of finding intelligent life in the universe. N = The number of civilizations in the Milky Way galaxy whose electromagnetic emissions are detectable.

The Pioneer plaques are a pair of gold-anodized aluminium plaques which were placed on board the 1972 Pioneer 10 and 1973 Pioneer 11 spacecraft, featuring a pictorial message, in case either Pioneer 10 or 11 is intercepted by extraterrestrial life. The plaques show the nude figures of a human male and female along with several symbols that are designed to provide information about the origin of the spacecraft.

The Voyager Golden Records are phonograph records that were included aboard both Voyager spacecraft launched in 1977. They contain sounds and images selected to portray the diversity of life and culture on Earth, and are intended for any intelligent extraterrestrial life form, or for future humans, who may find them. Neither Voyager spacecraft is heading toward any particular star, but Voyager 1 will pass within 1.6 light-years of the star Gliese 445, currently in the constellation Camelopardalis, in about 40,000 years.

You can find his lengthy Q&A here. I highly recommend checking it out if you are remotely interested science and space exploration.
