Good ideas are often forgotten, but they do not die. They are discovered through reading, or created independently again. The recurring debate on whether humans should be in space omits such an idea. The relationship between human spaceflight and the survival of the human species was explained by the spaceflight pioneers Konstantin Tsiolkovsky and Robert Goddard, and has since been expressed by Stephen Hawking, Carl Sagan, and many others. Sagan’s thoughts are of particular interest, since he devoted his career to space science and the search for extraterrestrial life, not human spaceflight.

It seems to me that Sagan changed his mind. I wonder why?

Sagan never really understood spaceflight as anything but a scientists sandbox, his view is sooo.....'80's.

SpaceShipOne’s Ansari X Prize breakthrough brought the world’s attention to the idea of personal spaceflight. Hopefully, a documentary will do the same for another important idea. The Discovery Science channel needs to update their documentaries, I saw one just last week talking about how the Venture Star was going to revolutionize space travel. C'mon guys, that's just embarrasing.

Sagan was a Polictico-Scientist who was always at odds with NASA and the Manned Space Flight crowd. He was far more interested in fame and money for me to ever take him seriously.

Your not talking about the Black Sky documentaries they did about Rutan did you? Because there were two, a two hour one about Rutan's runup to the X-Prize, and then a one hour documentary about Rutan winning the X-Prize. I'd hardly call that outdated (although Wings does run several "Future Wings" and "Aeropace" shows that are very outdated).

No this was on the Science channel, the Rutan documentary was great, but they have a whole slew of older ones that are over 5 years old.
