ROSES-11 Amendment 8: Appendix A.31, The DESDynI Science Definition Team solicitation, is temporarily suspended.

Appendix A.31, The DESDynI Science Definition Team (SDT) solicitation in ROSES 2011 is temporarily suspended pending release of a subsequent amendment, which is expected no later than June 7, 2011. It is anticipated that the proposal due date for the revised call, focused upon an L-Band SAR only mission, will be September 7th.

The DESDynI SDT was solicited in anticipation of progress to the formulation stage for the DESDynI mission. The more recent 2012 Administration budget requires that the DESDynI mission be re-formulated as an L-Band SAR only design to meet reduced budget guidelines. The current DESDynI Science Study Group is requested to continue to serve the mission pre-formulation effort only until the SDT for the L-band Synthetic Aperture Radar (SAR) mission is selected in early 2012.

The L-Band SAR Science Definition Team will include scientists with expertise in radar scientific data analysis, applications, and/or technology. Information about the size of the team, its leadership, and its expected disciplinary scope will be described in the forthcoming amendment.

On or about May 13, 2011, this Amendment to the NASA Research Announcement “Research Opportunities in Space and Earth Sciences (ROSES) 2011” (NNH10ZDA001N) will be posted on the NASA research opportunity homepage at http://nspires.nasaprs.com/ (select “Solicitations” then “Open Solicitations” then “NNH10ZDA001N”).
