Philae comet lander falls silent
The fridge-sized robotic lab, which in November landed on comet 67P/Churyumov-Gerasimenko, last made contact on July 9 and efforts to reach it again have so far failed, said experts at the European Space Agency project.
The lander — the first mission to land on a comet — initially bounced and landed in a position too shadowy to power its solar panels.
