Chandra’s Surface Thermophysical Experiment (ChaSTE) has become the first instrument to measure temperatures in situ near the moon’s south pole.
It also became the first mission to successfully penetrate the soil of a celestial body to deploy a thermal probe after two previous missions had fallen short.
In November 12 of 2014, the European Space Agency’s Philae lander, hitchhiking on the Rosetta spacecraft, landed on comet 67P/Churyumov-Gerasimenko.
It also contains same kind of instrument, but they couldn’t deploy it due to the awkward landing position.
