Is it just me or does it scare you to know satellites which can obviously return to earth for a variety of reasons can at times have onboard nuclear reactors. This is an important point as you may have heard an Iridium Satellite recently collided with a Russian military one.

And that is the good news. The bad – the Russian satellite could be nuclear.

And this it seems is how the world’s top scientists design things. How does the conversation in the lab go? Let’s hurl this two ton nuclear-powered object into space and hope it doesn’t hit anything else?

Truly amazing.
