The coolest news of the day has to be the item about the Ice reservoirs found on Mars. The presence of such a vast amount of ice - if it were to melt it could cover the planet in an ocean at least 500 metres deep (1,640 feet) - will change profoundly the direction of future exploration. When will it be time to pack up our swimwear and start planning the trip?

And there's sad news also, because I had not mentioned the death of Bart de Graaff on sunday, when I first heard it. Very sad.
