I spent Monday helping film the next Sky at Night, which is all about the MESSENGER mission to the planet Mercury. How could it not be? It’s shown us part of a planet (a real planet, not this Pluto nonsense) that we have never seen before. The first results have been stunning; at first glance it’s a world that looks like the Moon, but in detail it’s very different.
There’s a press conference going on now which you can watch online and I’ll write about everything they announce that didn’t make it into the program tomorrow.
