I recently attended a lecture given by Prof John Zarnecki called "Fingers Crossed - 50 Years of Space Exploration".
Sending rockets into space and expecting them to work has always been a dodgy business. The Prof talked about some of his experiences starting with almost meeting Yuri Gagarin and working through his first xray rocket, Hubble FOC, Giotto, Beagle 2 and Huygens etc. Very interesting.
Anyway, the lecture is now available online at the BBC/OU Website.
Cheers,
Chris.
