Amendment 24: Final text and change of submission and target selection process for D.7 K2 Guest Observer – Cycle 6

K2 Guest Observer (K2GO), program element D.7 of ROSES, 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 fields covered by the observing campaigns under Cycle 6 are described at https://keplerscience.arc.nasa.gov/k2-fields.html.

K2GO6 will use a new two-phase submission and target selection process, since spacecraft fuel is estimated to run out during these observations. An optional Phase-1 proposal, for all three campaigns (17-19) combined, will enable targets to be selected ahead of the observing campaigns. Phase-1 proposals, including target lists and a scientific rationale (submitted via email to keplergo@mail.arc.nasa.gov) are requested by October 12, 2017. If the spacecraft health and fuel allow, then Phase-2 proposals will be due April 19, 2018 (via NSPIRES). Phase-2 proposals are limited to use observations for targets which have been selected as part of Phase-1, the selection results of which will be published in February 2018 at https://keplerscience.arc.nasa.gov.

On or about August 17, 2017, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2017" (NNH17ZDA001N) will be posted on the NASA research opportunity homepage at http://nspires.nasaprs.com/ and will appear on the RSS feed at: http://nasascience.nasa.gov/researchers/sara/grant-solicitations/roses-2017. Technical and implementation questions should be directed to: Geert Barentsen at geert.barentsen@nasa.gov.
