Are you telling me it will take 46 yrs for the orthodoxies to realise, dynamic behaviourism is the technologies which will enable faster in time and zero g attributes.
Counting from now.

I watch old Carson episodes now and then. Totally forgot about Sagan's appearances until I saw this.

I wonder does solar sail allow travel from outer to inner planets in the solar system? Or just from inner to outer planets?

I saw that! I remember watching that and thinking how cool it was. I miss Carl Sagan he was a wonderful communicator and ambassador for science. I’m so grateful he helped to give the world to carry on that legacy.

He never successfully explained how one could ‘tack in to the sun’. A large parachute being blown by the solar wind is nothing like a sailboat which relies on wind & water.
