It's amazing how you can miss things
I was completely unaware of the Mars Helicopter. So that's excellent news, and another cool thing for the next NASA Mars rover to do.
While I'm here talking about space, I hope nobody minds a little plug - I am not affiliated with this in any way, just an interested listener. The BBC World Service have a newish program/podcast out called 13 minutes to the Moon. Up to episode 4 now, but it's a podcast so you can download.
It's a bit repetive, in the way so many documentaries feel they have to be nowadays, and sometimes veers around the subject a bit to account for short attention spans. But I think it's pretty damned good. The schtick is that they're focusing on the final 13 minutes of the Eagle's landing on the Moon - and taking bits of the recorded radio conversation each episode, to go off and explain the various technical challenges and problems they had to overcome. With as I understand it, the final aim being that you'll be able to listen to the audio feed uninterrupted (in a later episode), and by that point recognise most of the voices and jargon so you can understand what they're talking about.
I've not read about Apollo in ages, and it's inspired me to look for Michael Collins 'Carrying the Fire' and Gene Krantz 'Failure is not an Option' - so it's already cost me a few quid...
