The first of five scheduled missions in 2010, Endeavour’s STS-130/20A flight will deliver and install the final US module to the ISS. This module, the Node-3 and adjoining Cupola unit, is currently undergoing processing for flight in the Space Station Processing Facility (SSPF) at KSC. Endeavour, processing in OPF-2, is deep into her STS-130 flow, following her return from the highly successful STS-127 mission which delivered the final piece in the Japanese jigsaw on Station.
“MPS (Main Propulsion System) flowliner inspections continue in work. Picking up with preps for FRCS (Forward Reaction Control System) installation,” noted a Standup level report overview of processing. “The FRCS will be coming up in the HMF (Hypergolic Maintenance Facility) this week; will install this coming Saturday.”
Endeavour’s flow was expanded on during the latest daily processing update, which listed no issues in work for the youngest orbiter in the fleet.
“Fuel Cell 2 R&R picked up on Monday and is continuing. The old fuel cell 2 has been removed from the orbiter and installed into its shipping container. MPS 12in flow liner inspections are continuing. Water Spray Boiler (WSB) checkout and servicing picked up Monday and is continuing.
“Window 7 removal was completed Monday and new window installation is in work. Hydrogen separator R&R began Tuesday. APU (Auxiliary Power Unit) leak checks and GN2 QD heater functional picked up Tuesday. LOMS engine GN2 relief valve functional is scheduled to pick up on second shift Tuesday. ROMS engine GN2 relief valve functional is planned for Wednesday.”
