Interesting. Every space exploration gives me thrills. It's a shame we stopped the space race after the Cold war. There is so much to discover even in our orbit, Moon, not speaking of Mars yet, those NASA news were amazing last year. I once wanted to put camera with a gps in a basket with a helium filled baloon. Just to capture some photos for my collection. Apparently I didn't do it because of risk of losing 2000$ camera etc. Well, maybe next time. Sorry for off-topic, upvoted.
