As part of the preparations for the 2020 Decadal Survey, in August 2016 NASA issued a ROSES solicitation (ROSES2016, NNH16ZDA001N, Appendix D.12) for studies of medium-size (“Probes”) mission concepts. On November 15, 2016, 27 compliant proposals were received. The peer review was held in January 2017.

In March 2017, NASA made the following selections:

Selected Probe Mission Concept Studies

All the selected proposals were highly rated by the peer-review panels based on merit and other criteria stated in the ROSES solicitation. Selection of the listed proposals follows programmatic criteria as well as taking into account the panels’ guidelines for a diverse portfolio addressing a variety of science questions.

The selected Teams will receive funds for an 18-month comprehensive study. NASA will also provide design lab runs and a final Independent Cost Assessment for the selected studies.

The selection decision document will be posted at under Probes Mission Concept Studies.
