ESA and JAXA join forces

ESA Director General Jan Wörner and Hiroshi Yamakawa, president of the Japan Aerospace Exploration Agency (JAXA), signed an agreement on 14 June 2019 to cooperate on Xrism – the X-Ray Imaging and Spectroscopy Mission. Xrism will study the hot gas plasma wind that blows through galaxies in the universe. These observations will enable scientists to determine flows of mass and energy, revealing the composition and evolution of celestial objects.
