ESA CAVES 2016 - Stalagmites

3D Model

3D model of Tiscali cave stalagmites in Sardinia, Italy, made by the team of astronauts taking part in ESA’s underground training mission CAVES 2016. This model was made using photogrammetry, a three-dimensional survey technique using photographs that could also be used on other planets, for example to study lava tubes on Mars.
