Explorer of Enceladus and Titan Explorer of Enceladus and Titan Explorer of Enceladus and Titan (ET) is a space mission concept that would investigate the evolution and habitability of the Saturnian satellites Enceladus and Titan and is proposed by the European Space Agency in collaboration with NASA. The proposed mission would address key scientific questions regarding extraterrestrial habitability, abiotic/prebiotic chemistry and emergence of life, which are among the highest priorities of ESA's Cosmic Vision program. The Explorer of Enceladus and Titan (ET) orbiter was first proposed in 2017 as a medium-class mission led by the European Space Agency in collaboration with NASA in response to
