Study Schedule

A number of milestones have been identified for the Athena Assessment Study. The dates are still TBC, but defined to ensure the mission is ready for "adoption" into the Science Programme in late 2018 / early 2019. This adoption is the most important decision point needed to embark on the flight hardware procurement phase, leading to the 2028 launch.
