Pathfinder Science for a Potential
Chandra Successor Mission (CSM)

DEADLINE: Wednesday 24 January 2018, 6PM EST.

About this Call

The purpose of this special Chandra call is to propose for new Chandra observations that can demonstrate the feasibility for key CSM goals or otherwise enhance CSM science prospects. Proposals from all areas of astrophysics will be considered. It is anticipated that the results of these pathfinder studies will inform the CSM science case(s) to be considered by the 2020 Astrophysics Decadal Survey Committee.

The Chandra X-ray Observatory (CXO) has enabled many ground-breaking discoveries because it is the first X-ray mission with sub-arcsecond imaging and spectroscopy. Requirements for a CSM include large gains in collecting area over current missions, coupled with high angular resolution and a large field of view. Lynx is one example of a potential CSM, and is one of four Large Mission concept studies funded by NASA in preparation for the 2020 Astrophysics Decadal Survey.

Up to 1 Msec of Director's Discretionary Time (DDT) may be devoted to CSM programs. Approved CSM Programs will be scheduled during Cycle 19 (calendar year 2018) as feasibility allows. Funding is available to eligible PIs/CoIs at the same level as for General Observer Programs. Successful proposers will be allowed a full year of proprietary time for CSM targets. No archive or theory funds are available for this Call.

Notes on Using the Proposal Software

The DDT RPS proposal submission interface that will be used for this Call is designed for transient science.

The DDT RPS allows for upload of a single Science Justification pdf. CSM page limits will be given in the Call for Proposals and are different from the 1 page limit given for DDT proposals.

Proposers who are requesting time for non-transient targets should fill out the forms as follows:
