Today is Carl Sagan’s birthday. He would have been 78 years old.
Carl is best known for his Cosmos series, a PBS production, that explored and explained the wide-range of science. The thirteen-part series spanned the history of universe, and brought the wonders of science into people’s homes. His infectious energy and excitement for all things science was easily recognizable and Carl quickly became the much-beloved face of science for many.
In addition to his desire to bring the sciences to the masses, Carl sought to bring humanity into the cosmos. A long-time believer in exterrestrial life, Carl worked for many years at SETI. He advocated for and helped design the Pioneer plaques and the Voyager Golden Record, with the hope that maybe, one day, they would be encountered by intelligent life forms other than our own.
In time, Carl became more politically active. A peaceful person, he opposed the expansion of nuclear arms, believing that nuclear energy would be best utilized for exploratory purposes rather than destructive.
Upon his death in 1996, president of the National Academy of Sciences Bruce Alberts said of Carl:
Even 16 years after his death, Carl remains a popular and captivating figure. Recently, a YouTube series was produced in Carl’s name, pairing some of his most popular speeches and quotes with awe-inspiring images of the Earth and cosmos.
Above is the first episode of Cosmos. Enjoy.

NASA:
In the 1960’s U.S. Government laboratories, under Project Orion, investigated a pulsed nuclear fission propulsion system. Small nuclear pulse units would be sequentially discharged from the aft end of the vehicle. A blast shield and shock absorber system would protect the crew and convert the shock loads into a continuous propusive force.
In his book and companion series Cosmos, Carl Sagan discussed Project Orion, describing it as “providing a kind of putt-putt, a kind of nuclear motor boat in space.” He expounded Orion as the best use of nuclear weapons, “provided they do not depart from very near the Earth,” in order to reduce the risk of fallout.
The 1963 Partial Nuclear Test Ban Treaty, however, killed the Orion Project, as it “prohibits nuclear weapons tests ‘or any other nuclear explosion’ in the atmosphere, in outer space, and under water.”
