>It will be a topic because OV-104 must be ready to fly STS-300 if needed.<<br /><br />I also wonder if this will be a topic for the Stafford-Covey RTF Task Group final meeting on Monday, seen as they are there to note completion of the CAIB requirements (of which an STS-300 is one of them).<br /><br />So allow me to clarify this:<br /><br />I have the FRR as "The FRR, held approximately two weeks prior to launch, is a comprehensive review of all activities/elements necessary for the safe and successful conduct of all operations from prelaunch through post–landing and recovery operations. The readiness of the Space Shuttle vehicle, flight crew, and payloads is determined at this review. A signed Certification of Flight Readiness endorsement certifies that all have successfully completed their Flight Preparation Processes."<br /><br />So Discovery is ready by all intents and purposes, but Atlantis has to be projected as ready within that window for a potential - yet undesirable - STS-300, to complete the circle on the requirements for Discovery to launch, at which point the clock starts ticking for Atlantis to be ready.<br /><br />You mentioned a potential two-week addition to OV-104's flow - does that break into this timeline? I'm not sure of the current progress of Atlantis' flow before the aforementioned ECO sensor box situation, such as contingency days remaining on her flow.
