Space is the ultimate definition of an advanced industry. Its technological frontiers must be continually rolled back, but at the same time, maximum autonomy and total equipment reliability must be guaranteed. Our unique expertise in cryogenics has made Air?Liquide a major contributor to space exploration for more than 50?years. We take part in the largest international projects, including the European Ariane launcher program, satellite programs (primarily Herschel, Planck and MeteoSat Third Generation) and the International Space Station (with the MELFI cold storage system).
