--- Quote from: downtowneddie on 17 Feb 2015, 08:45 ---I'm watching live, on NASA TV, the docking of a Russian Progress cargo ship to the International Space Station and it amazes me how engineers have figured out orbital mechanics so precisely that a rocket can be launched from the ground, catch up with a moving target (going 17,500 mph, mind you!) some 250 miles up, do a little orbital ballet, and then dock.

What's more amazing is that they figured this out 50 years ago.
