1000 m!
The core run that passed the 1000 m had just reached the surface.

1000 m! Today at 17:00 we crossed the 1000 m mark, unfortunately the core from 1000 m driller's depth is crushed, completely. Due to triple tube drilling: still 100 % recovery, even of the crushed parts. Presently, we assume that the fracturing is induced, and we will learn more about the rock quality in the next core runs. But we also encountered some altered surfaces with "loose material" that we sampled for the microbiologists. Some adjustments to the drill rig were made today, and we learned that replacement drill pipes for the crooked ones we have to drill with are on the way - from Canada! I hope the ships are fast …
