| 3.2 CLEANROOM ENVIRONMENTS The standard service temperature, humidity and cleanliness environments during various processing phases are provided in Table 3-1. Conditioned air will only be disconnected for short durations (generally between 30 and 60 minutes) during predetermined operations such as movements, lifts, and rollout to the pad. Payload environmental temperatures will be maintained above the dew point of the supply air at all times. The SpaceX supplied mechanical interface and fairing surface are cleaned to VC-HS.

Export Controlled Data. 8 3.3 FLIGHT ENVIRONMENTS This section describes the MPE the Payload will experience from liftoff through separation from the Launch Vehicle. IMPORTANT To ensure mission safety, Payloads must test all flight hardware as a fully integrated Payload everything, including all Payload Constituents that comprise the Payload and attach to the SpaceX provided mechanical interface) consistent with the requirements defined in Sections 3.3 and 3.4. Integrated flight hardware testing provides workmanship screening as well as validation of design analyses for the entire Payload assembly. This testing is required to ensure safety of the primary Mission and of Co-Payloads. Download 2.78 Mb. Share with your friends:
