The exploration of subglacial worlds is one of the greatest technological challenges for both space science and terrestrial glaciology. Within TRIPLE, initiated by the German Space Agency at DLR, technologies are being developed to address these challenges. One of the projects within TRIPLE is TRIPLE-IceCraft. Its goal is the development of an electrothermal drill as a terrestrial demonstrator for transporting payloads through an ice sheet of several hundred meters at a drilling velocity of several meters per hour. The same-named drill, TRIPLE-IceCraft, is a modular system including a cable which can be coiled and uncoiled into a dedicated compartment. The cable bears the weight of the drill and is used for communication and power. This allows the refreezing of the melt hole including the cable, so it can be operated even in cold glacial ice. The demonstration of the TRIPLE-IceCraft is planned close to the Antarctic research station Neumayer III located on the Ekström Ice Shelf in 2023. In this poster, we focus on the technical design of the TRIPLE-IceCraft.
