The main issue I read was that even though it gets some light (something like 1 hour of light per 12 hours) the battery can't recharge when it's cold. So Philae needs light to heat up the battery and only then it can start charging it so it needs a longer exposure to sunlight or it needs to be closer to the sun so it heats up faster.
- gerry_mander 12y agoI thought solar panels were more efficient when cold...
- simias 12y agoMost electronics are more efficient when "cold", but when we say that we mean "cold" by our earth standards, i.e. something like 15 degrees celsius. I think I read that Philae's temperature after landing was less than -160 degrees celsius. Getting anything to work at those temperatures is hard...
