A little less analogue, and a lot more crap.

Great news, we could be in for some fantastic pictures, fingers crossed:)

Once past the closest point to the sun - if all goes well - Rosetta is expected to be moved into a really close orbit, and when the fuel is depleted, the team expect to 'land' the orbiter, giving more opportunities for close up images.

Philae may have been saved by the temporary loss, since the normal 'daytime' temperatures at the end of next month on 67P/Churyumov-Gerasimenko are apparently outside its working parameters.

And one more desperate attempt


Scientists initiated Friday a last-chance manoeuvre to contact a long-silent robot-lab dropped more than a year ago onto the surface of a comet hurtling through our solar system.
Scientists sent a command to the fridge-sized robot to spin up its flywheel, initially used to stabilise the probe when it landed.

The hope is that so doing will "shake dust from its solar panels and better align it with the Sun", explained technical project manager Koen Geurts.

It is also possible, however, that the command—routed through the Rosetta spacecraft orbiting the comet—will never even reach Philae.

Several further attempts will be made, he added.

"It's an admittedly desperate move," Philippe Gaudon of the French National Space Agency told AFP. "It is very unlikely the robot will become functional again."

Final window for Philae to phone home - the temperature on the comet will fall below -50C by the end of January and thats it - the lander will be outside its operating range.

Brilliant that they have solved what happened to Philae before Rosetta is binned.
