Subject: Solar Probe Plus AO Amendment 1: Revisions to Table 4 and Table B3 NNH10ZDA002O Release Date: December 3, 2009 Proposals Due: March 26, 2010 With this amendment, the NASA Announcement of Opportunity (AO) NNH10ZDA002O, “Solar Probe Plus Investigations,” has been amended to revise Table 4, Schedule for Solar Probe Plus Mission, and Table B3, Total Mission Cost Funding Profile Template. Table 4, Schedule for Solar Probe Plus Mission, has been revised to include a new planning date for the start of Phase B and a new planning date for the end of Phase F. As stated in Section 5.3.1 of the Solar Probe Plus Investigations AO, the schedule in Table 4 is a planning schedule (which may be revised during Phase A) and should be the basis for the schedules in the proposed investigations.
