Ross-15 Amendment 32:
Release of K2 Guest Observer Cycle 4

ROSES-15 Amendment 32: This amendment releases a new opportunity, K2 Guest Observer (GO) Cycle 4, in Program Element D.13. The text in this program element is different from that which appeared as K2 GO Cycle 3 in program element D.7, so please read it carefully.

Program element D.13 of ROSES-2015 solicits proposals for the acquisition and analysis of new scientific data from the K2 mission ( K2 repurposes the space-borne hardware and ground-based operations of the Kepler mission ( for a pointed survey of predetermined locations along the ecliptic plane. The single, visible-wavelength instrument on board K2 provides high-precision photometry capability, with short cadence and long cadence modes (1 minute and 30 minute exposures, respectively), and provides a powerful tool for broadband variability analyses of planetary, stellar, extragalactic, and solar system sources.

The execution of the K2 Guest Observer Cycle 4 is contingent upon the outcome of the 2016 Senior Review. Mandatory Step-1 proposals are due February 5, 2016, and Step-2 proposals are due March 4, 2016.

On or about December 2, 2015, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2015" (NNH15ZDA001N) will be posted on the NASA research opportunity homepage at and will appear on the RSS feed at:
