Astronomy and Physics Research and Analysis (APRA)

This amendment announces new due dates and revisions to Appendix D.3 of ROSES-2007 entitled Astronomy and Physics Research and Analysis (APRA).

The proposal due dates for APRA have been changed to be several weeks earlier than previously announced. Notices of Intent to propose are now due February 15, 2008, and proposals are now due March 28, 2008.

The following changes have been made to the APRA program element text:

- Awards may be for up to four years duration (up to five years for suborbital investigations).

- Proposals for suborbital investigations are particularly encouraged. Suborbital investigations not only execute meritorious science investigations, but also advance the technology readiness of future space flight detectors and prepare the future leaders of space flight missions.

- Additional funding is available for suborbital investigations.

- The balloon program is providing a shared platform capable of carrying multiple, independent, piggyback-like instruments, in order to offer suborbital flight opportunities to more users.

- The special instructions for multiple institution proposals for suborbital investigations have been revised.

- Investigations for rapid searches for counterparts to Gamma-ray bursts are no longer eligible for support within the APRA program.

Proposers should read the revised text carefully.

On or about December 14, 2007, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2007" (NNH07ZDA001N) will be posted on the NASA research opportunity homepage at (select Solicitations then Open Solicitations then NNH07ZDA001N).
