Abstract : IDA was tasked to conduct an External Independent Readiness Review (EIRR) of the EOS AM-1 spacecraft following the Critical Design Review (CDR). The briefing provides an overview, which covers the EIRR participants, the EIRR process, and the Overall Assessment resulting from the EIRR; a Spacecraft Systems Assessment, which contains a subsystem by subsystem assessment of the EOS AM-1; a discussion of higher level (i.e., Program level) concerns; and a summary and recommendations. EOS AM-1 is an ambitious program with a significant amount of innovative hardware and moderate schedule risk. The greatest risk associated with the program at the present time appears to be maintaining schedule. Major areas of concern are the following: (1) impact on the program if solar array cracking resolution and the many ongoing lifetime tests of various components are not concluded as successfully as anticipated; (2) the increased schedule risk resulting from the use of a large number of components with no space heritage; and (3) impact on the program should the Atlas IIAS launch pad be delayed or otherwise unavailable when anticipated.
