Planetary Deep Drill support wire and umbilical
Planetary Deep Drill support wire and umbilical Taken at the first field test of the Planetary Deep Drill in December 2015: With the drill many meters down this hole into gypsum, all one can see entering the hole in this picture is the support wire and the umbilical carrying power and data down to the drill as it works.
