Anyone want a Useful Box for Putting Things In?

Specifically, a Lacie Firewire external hard drive case.

You'd probably want to put an ATA133 hard drive in it; it has rather too many gnawable little wires to be an adequate case for carrying around fancy mice, it's a bit too small for a hamster, and has too many air vents to be used for displaying a collection of multi-coloured sands.

Dynamic geography on Mars

Mars Global Surveyor, unsurprisingly given its name, surveyed the whole globe of Mars in 1999.

After this, it still had plenty of fuel, so looked at a wide variety of parts of Mars in greater detail; enduring further, and the scientists having run out of really exciting parts of Mars, it was returned to surveying, and covered 30% of the whole globe of Mars before breaking down last month.

It's not too difficult a job for a computer to check what's changed; sediment seems to have been deposited in various gullies, which are presumably now very high up the list of Places People Want To Visit, but being gullies on the steep sides of craters are a bit difficult for current robots to get to.

And there have been 20 new craters formed, including one about fifty metres in diameter with a debris trail half a kilometre long

It would be moderately inconvenient if a fifty-metre hole appeared randomly on Earth every year or so, but meteorites that size burn up in the atmosphere, with a flash of the energy of a modest atom bomb but far enough up that it's noticed only by such organisations as interest themselves in knowing with alacrity whenever anything atom-bomb-like has happened, and admitted to the public only when a functionary at such an organisation has nothing better to do; thank Boreas, Zephyr, Notus and Eurus for arranging Earth an atmosphere a hundred times denser and more meteorite-proof that Mars's.
