The first drill bit wore out after about 180 m of drilling, 284 m depth of the COSC-1 drill hole. Something is not optimal with the lowermost part of the drill hole and the drillers have to ream/"redrill" in order to reach the former depth with the new bit. This gave us some time to catch up with the core documentation, to take the first samples for the study of (time-dependent changes in) thermal conductivity, to get the necessary non-scientific tasks done. And to almost be idle ... but we have now experienced how things can changes very fast from one extreme to the other. Soon the race will start again!
