Data received before the cut - off suggests the drill had reached 25 centimetres below the spacecraft, but with Philae
standing in a precarious position, with one leg in the air, the drill may not make it to the surface to take a sample.
As you move between the highly stable
standing position and the more
precarious split stance, the change
in stability demands you simultaneously resist and produce force, something it shares with both bird dogs and sled work.
