The LIFE initiative (LIFE = Large Interferometry For Exoplanets) has the goal to develop the scientific context, the technology and a roadmap for an ambitious mid-infrared nulling interferometer space mission that will allow humankind to detect and characterize the atmospheres of hundreds of nearby extrasolar planets including dozens that are similar to Earth. Additional motivation for the initiative is provided by the outcome of ESA ’s “Voyage 2050” process and the corresponding recommendations from the ESA Senior Committee: the direct detection of the thermal emission of temperate terrestrial exoplanets was given very high scientific priority and is considered as a candidate theme for a future L-class mission. In this talk I will discuss the scientific potential and unique discovery space for a mission like LIFE , in particular for the detection of atmospheric biosignatures. Synergies with, but also advantages over future NASA flagship missions will be described and an overview of ongoing technology developments and related challenges will be provided.
