The China Space facebook page reports the lander has awaken (Link).
I haven't heard anything about the rover. -------------------- -- Hungry4info (Sirius_Alpha)

Great!
One question, for people (like me) who are not experts for electronics hardware at low temperatures: What is the problem with the low temperatures? What exactly happens, how is the electronics knocked out? Thanks for the answers. Thorsten |

What is the problem with the low temperatures? Thermal expansion/contraction can break solder joints, internal bond wires, etc. Some components (e.g., electrolytic capacitors, batteries) have goop that can freeze. In general it's not that hard to build something that can survive Mars surface temps, but it gets colder and hotter on the Moon, so more stress. -------------------- Disclaimer: This post is based on public information only.
