What were the lows of the Beagle II mission?

Colin Pillinger (Professor of Planetary Sciences) gives expert video advice on: How was Beagle born?; Why did you launch the Beagle mission?; What is Beagle II? and more...

I don't have lows. If I'd had lows on the Beagle II mission, people would've stopped. I had to be the guy who was always convinced that it was going to happen. I wasn't allowed to have lows. You can say now that, “You haven't failed until you've stopped trying.” If we haven't stopped trying on Beagle II, we haven't failed yet.
