A lot of my friends are astrophysicists and aeronautical engineers, but I’ve never done any research in those areas myself. Nuclear offers a lot of promise in space because it is so energy dense – that means that more energy can be extracted from a smaller mass of fuel (which means that cheaper spacecraft can be manufactured).
Yes, my undergraduate degree was in Physics and Astrophysics. For my 4th Year project I used computer simulations to map the distribution of dark matter through time (since the Big Bang) and use this to understand how galaxy groups and galaxy clusters are formed. That feels like a very long time ago now 🙂 the work I do these days is completely different!
Unfortunately I haven’t (even though I’ve always loved space and still dream of being an astronaut) but something I learnt recently is that a lot of things up in space right now are being powered by nuclear energy. Nasa use radioactive isotopes like plutonium-238 basically as a super-reliable battery because it can create heat all by itself!
not really but i studied geology at university and we got to look at samples from the moon brought back from a lunar mission which was pretty cool. they had some pieces of meteorite too i am pretty sure.
