ROSES-08 Amendment 23: New proposal opportunity for MOST U.S. Guest Observer Program – Cycle 1

This amendment announces a new proposal opportunity in Appendix D.10 entitled “MOST U.S. Guest Observer Program – Cycle 1.” This program element solicits proposals for the acquisition and analysis of new scientific data from the MOST (Microvariability and Oscillations of STars) observatory through a partnership between NASA and the Canadian Space Agency (CSA). Observations associated with the MOST U.S. Guest Observer — Cycle 1 solicitation will begin on or around February 1, 2009 and awards will have a 12-month duration. The MOST mission is designed to conduct photometric studies with high precision sufficient to perform stellar asteroseismology studies and other variability analyses of stars and exoplanet systems. GO investigations may address any area of astrophysics and are not restricted to asteroseismological studies. Investigations may range from the study of a single target to many targets per field, and should optimize the amount of science that can be derived from a single pointed observation (field).

Notices of Intent (NOIs) to propose are due August 29, 2008. Proposals are due October 6, 2008.

On or about July 31, 2008, this Amendment to the NASA Research Announcement “Research Opportunities in Space and Earth Sciences (ROSES) 2008” (NNH08ZDA001N) will be posted on the NASA research opportunity homepage at http://nspires.nasaprs.com/ (select “Solicitations” then “Open Solicitations” then “NNH08ZDA001N”).

Questions concerning this solicitation may be addressed to Dr. Padi Boyd, Astrophysics Division, Science Mission Directorate, NASA Headquarters, Washington, DC 20546-0001; Telephone: (202) 358-2368; E-mail: padi.boyd@nasa.gov.
