X-ray Surveyor, now called Lynx, is a large (strategic) mission concept identified in the 2013 Enduring Quests, Daring Visions NASA Astrophysics Roadmap. A Marshall Space Flight Center-based Study Office is conducting a Mission Concept Study under the leadership of a community-selected Science and Technology Definition Team (STDT). It is anticipated that the 2020 NRC Decadal Survey Committee will use this and other studies in formulating their recommendation for the priorities for large strategic missions of the future.

The X-ray Surveyor/Lynx Study Office provides this website to convey STDT activities to the science community and to the general public.
