I don't usually say things like, "this is SO COOOOOL!" but I have to make an exception for this picture. It is a photo taken by the Mars Reconnaissance Orbiter of the Phoenix and its parachute descending through the Martian atmosphere to the arctic plains below.
It is stunning to think that these machines are going about their business so far away from us that even light at the moment takes 15 minutes to get to us.
Whenever I talk to people about this kind of thing I always seem to end up in arguments about how the money could better be spent on improving the world somehow. But, firstly, this DOES improve the world AND I feel it's a lot more justifiable than spending millions on football players or Hollywood spectaculars not to mention the incredible sums that we spend just to be able to blow each other to smithereens.
