A history of aerothermodynamic activities in the European Space Research Organization/European Space Agency (ENRO/ESA) is given. Between 1964 and 1988 these were devoted to satellite aerodynamics for low Earth orbit missions and rocket engine exhaust plume dynamics. The creation of an aerodynamic capability at the European Space Research and Technology Center (ESTEC) is mentioned, and the programs involving substantial aerothermodynamics are listed. The aerothermodynamic challenges for future ESA mission in its science, Earth observation, and space transportation programs, are addressed, and design solutions offerred. Within the science programs the Cassini/Huygens, Rosetta, and Mars missions are considered. Within the Earth observation programs the Aristoteles mission is considered. Within the space transportation programs, Ariane-5, Hermes, and reusable winged launchers are considered. Design tools and engineering facilities needed for modern aerothermodyanmics are discussed; ESA's research and development activities in aerothermodynamics are addressed. One of these activities is to prepare and implement a Technology Research Program (TRP) designed to prepare the technology needed for Europe's space program. Activities in progress or planned within the TRP are addressed. They include development of Navier-Stokes algorithms, work in aerothermochemistry effects in hypersonic flows, work on parallel processing for aerothermodynamics, transition criteria in hypersonic flows, and work on measurement techniques in hypersonic flows.
