PCOS Mission Studies

2013-2014 X-ray Probe Study

NASA's Physics of the Cosmos (PCOS) Program established a Science and Technology Definition Team (STDT) to study concepts for a potential reduced-scale strategic spectroscopy X-ray mission with total mission cost less than $1B in FY 2013 constant year dollars. The X-ray Probe (XAP) STDT was constituted to assist the Astrophysics Division, through its PCOS Program Office, in developing a reference mission concept of high scientific, technical, and programmatic merit that would both address the X-ray science goals and program prioritizations of the Decadal Survey New World New Horizons (NWNH) for X-ray astrophysics and be executable within the Astrophysics Division's notional budget profile. For further details, see the Call for Letters of Application for Membership in the Science and Technology Definition Teams for Reduced Scale X-ray Mission Concepts.

The mission study was ended with the 2014 selection of the Athena mission in Europe, at which point NASA began efforts to partner with ESA on Athena. Please see the Athena study page for more information.
