The lander is now stable but not anchored to the surface. They are getting data and pictures back from it!
The downside is the only thing keeping the lander on the comet is it's weight. The screws in the feet can't get a grip, and the harpoons didn't fire. That probably rules out drilling into the surface for the time being, in case it just pushed the lander away. They are still trying to locate exactly where the probe has come to rest.
*edit* from analysis of the images coming back "We're either looking into a ditch or we are against a wall" which might explain why the lander is stopped and why the radio transmissions are more intermittent than expected.
"We are sitting with the weight of the lander somehow on the comet. We are pretty sure where we landed the first time, and then we made quite a leap. Some people say it is in the order of 1 km high. And then we had another small leap, and now we are sitting there, and transmitting, and everything else is something we have to start understanding and keep interpreting." - project manager Stephan Ulamec
