Proposals Due: February 15, 2012

With this amendment, the proposal due date for NASA Cooperative Agreement Notice (CAN) NNH11ZDA012O, "NASA Astrobiology Institute (NAI) - Cycle 6," has been delayed to February 15, 2012. Due to the large number of time consuming activities between November and the end of January encountered by the Planetary Science and Astrobiology community, the proposal due date for the NAI Cycle 6 CAN has been changed to February 15, 2012.

On or about December 5, 2012, Amendment No. 1 to the "NASA Astrobiology Institute Cycle 6" CAN (NNH11ZDA012O) will be posted on the NASA research opportunity homepage at http://nspires.nasaprs.com/ (select "Solicitations" then "Open Solicitations" then "NNH12ZDA002C").
