Sun's out, guns out: Plucky Philae probot WAKES UP ... hits 'snooze'

Matthew 17

Re: Excellent work!

When you're in direct sun the temperature can be well over 100 degrees, as soon as you walk into the shade then it's almost absolute zero. Throw in the cosmic radiation on top and your cordless Black & Decker drill is going to have a hard time surviving.

There's a reason probes and satellites cost a few quid, they generally work in these extremes, and when they don't they usually enough redundancy and workarounds to enable them to carry on.

If you're going to go to the expense of building and fuelling a rocket to get your probe into space then you want to be reasonably sure that when it gets there it's going to work.
