Phil Perry Posted October 21, 2017 Share Posted October 21, 2017 This is an extract form an interview with Carl Sagan, conducted at 'Playboy Magazine' some time ago, where he poured scorn on the reasons for the International Space Station. . . Sagan: The shuttle is an attempt at bureaucratic self-maintenance. Playboy: You obviously disapprove of the program. Why? Sagan: When the Apollo program ended, there was no long-term goal for NASA; it had to invent a goal, and the shuttle was it. But, mostly, there is no reason for the shuttle. For example, the objective of the Challenger mission, which killed seven brave Americans, was to launch a communications satellite. But we’ve been launching communications satellites for decades with unmanned rockets that don’t risk people’s lives. Playboy: NASA says we need the shuttle to construct and maintain its proposed space station, Freedom. Sagan: But why do we need the space station? One answer: because the shuttle has to do something. Playboy: We would imagine you to be a staunch supporter of the space station. Sagan: What is it good for? Playboy: For starters, isn’t it a fairly exciting science lab in space? Sagan: For what? For observing the earth or the stars? No, because you do that with the robot satellites. So what is it for? For manufacturing in gravity-free environments? That was an original argument–you could make pharmaceuticals, cure cancer, make ball bearings–but you could tell very early that that was a fantasy. Essentially, no American corporation was willing to spend significant money on the space station as a place to do its manufacturing. You don’t hear much these days about space industrial parks. The full article. Interesting even if you don't agree with all his opinions: http://davidsheff.com/artic... Link to comment Share on other sites More sharing options...
octave Posted October 22, 2017 Share Posted October 22, 2017 I have read most of Sagan's popular books and admire him greatly. As a teenager, I was obsessed with astronomy and was a member of the astronomical society in Adelaide. I have read this article before and I both agree and disagree. It is very true that much of the science done on ISS could be done in other ways however there is another benefit in my view and that is the human interest aspect. The moon landings had a profound effect on my life. Even though we could (and the USSR did) send autonomous probes, there is something magical about a human visiting the moon. I quite like what Martin Rees, the Astronomer Royal said As Lord Rees says: "My view about manned space flight is that, as a scientist and practical man, I'm against it, but as a human being, I'm in favour of it." Also in 2015, he was co-author of the report that launched the Global Apollo Programme, which calls for developed nations to commit to spending 0.02% of their GDP for 10 years, to fund co-ordinated research to make carbon-free baseload electricity less costly than electricity from coal by the year 2025 But that is another debate Having said that I love regularly checking in to NASA TV to see work aboard ISS. I do also love the unmanned projects.The fact that the "experts" can send a probe over such amazing distances with such accuracy is mind blowing Link to comment Share on other sites More sharing options...
Phil Perry Posted October 22, 2017 Author Share Posted October 22, 2017 One of the most mind blowing probes I thought, was actually landing one successfully on a chunk of celestial rock, which only had a tiny amount of gravity ! . . . incredible use of technology that was. . .

Marty_d Posted October 23, 2017 Share Posted October 23, 2017 Carl Sagan was brilliant. Loved both the book and the movie of "Contact". If you're into believable hard-science SF, I can highly recommend the trilogy by Cixin Liu - start with "The Three Body Problem". Link to comment Share on other sites More sharing options...

I remember one enterprising lad who would pay his adult brother $20 for a couple of stick mags, cut the pages out, and sell them to other boys in class for $2 each. He's probably running a bank now.
