This document is intended to assist in the preparation of proposals responding to the 2011 Announcement of Opportunity AO, which is issued by NASAs Science Mission Directorate. NASA provides many operations and communications services for mission support. Costs accrue when using these services and stimulates of these costs need to be included in proposals responding to the AO. To facilitate proposal preparation, proposers are encouraged to read thisdocument and to contact the individuals named in Section 1.3 below.The NASA Space Communications and Navigation SCaN Office manages and directs three tracking networks to provide services for different types of missions. Several past proposal shave included Earth orbiting vehicles for which either NASAs Near Earth Network NEN or Space Network SN would be more suitable than the Deep Space Network DSN. For that reason, and to avoid early obsolescence of this document, a short description of each has been included. Functional responsibilities for NASAs three networks are shown in Figure 1-1. The SCaN Office has the overall responsibility to be the arbiter of mission requirements versus thee establishment of network tracking and navigation assets. While missions may have a desire for specific NASA facilities the SCaN Office will make the final decision on the provision of network assets.
