Today I went out to SPRESO (South Pole Remote Earth Scientific Observatory). It's an area the USGS has instruments buried in a vault about 6 km away from the station. We took a LMC 1800 tracked vehicle called 'The Wrench' out to it. In this picture the station is a spec in the far distance.
We climbed down into the vault to fix a problem CTBTO (Comprehensive Nuclear Test Ban Treaty Organization) was having. It's amazing that there are instruments down here at the South Pole checking for nuclear testing. In any case we replaced a malfunctioning hardware so Vienna could access the systems.
