A few years back NASA was testing an EmDrive .. based on some funky physics .. I wonder what happened to that research.

Didn't the movie Deep Impact feature an Orion based design? I vaguely remember nuclear propulsion being touted.

On a holiday to America when I was 13, I got this model rocketry set... this exact one:
There wasn't anything like it in the UK at the time, for anyone who hasn't seen these things, you build a rocket, put in a single-use engine & igniter with a wire to a battery powered hand control. Put the thing on the included launch pad an up it goes, the engine includes a final reverse jet that pushes the rocket's cone off which attaches to a parachute. Best toy I ever had (until the Rift came along).
Thinking back, it was probably against airline policy to bring back explosive rocket engines in the luggage hold.

Those were simpler times ..

I think Carl Sagan would argue that a much better use of money would be not to build rockets to send humans into space in the first place.

He so sadly died before my time but i am so in love with what Carl Sagan set out to do.
I literally watch an episode of Cosmos every 5am morning before i set out for my day
I must have watched The Lives of the Stars episode a hundred times, the description of a googolplex, the section on the elements and how the mass of a star dictates it's final outcome
A taster of the show... "how many consecutive cuts of an apple pie do you need to make before you arrive at a single atom?" .....ah, I was transfixed when that show first aired.
(the answer's 90 btw)
