🎥 Here is a 7-hour time-lapse of the preparation and start of drilling the first hole for the IceCube Upgrade. This elaborate procedure required a tremendous amount of hard work from the crew at the South Pole. As of last night, the drill had reached a depth of 340 meters! The start of drilling for the Upgrade comes almost exactly 15 years after drilling for the 86th hole of IceCube was finished on December 18, 2010! 🤯 🎥 Jennifer Wang and Vedant Basu, IceCube/NSF #IceCubeNeutrino Observatory
