Planetary Geomorphology

One of the major problems in the series of ice runs was that the subsurface temperature probes did not function. AIC re-evaluated the design and, after testing several suitable sensors, installed 50 type T thermocouples, each 2 m long. In this design, each thermocouple was soldered to a rectangular copper foil spreader 0.3 com wide by 2.8 cm long to ensure an acute reading. The long rectangular shape was used because it had a large area for good thermal connection to the test material.
