STS-119 (Discovery)

 2009-012A


The STS-119 mission 15A was to deliver the S6 truss to ISS.

Total mass delivered 14951 kg; 890 kg down MD, 518 kg H2O delivered. S6 mass 13635 kg per SSA, 14033 per MR; MD up 918 kg.

Discovery would carry up EMUs 3006 and 3017 and bring down EMUs 3004 and 3017, leaving 3006/3011/3005 on orbit.

EV astronauts were Steve Swanson (EV1, EMU 3017), Ricky Arnold (EV2, 3006), and Joe Acaba (EV3, EMU 3005).

Installation of S6 was unusually complicated. SRMS is used for viewing. SSRMS is based on MBS PDGF-1. The MT is moved to WS6. SSRMS then unberths S6 and hands it to SRMS. MT then is moved to WS1. SRMS hands S6 back to SSRMS and the SSRMS with S6 is then parked overnight.

The next day, on the first EVA Swanson and Arnold would support the connection of S6 to S5. They would install the RTAS (Rocketdyne Truss Attachment System) on S6 to S5, attach utilities cables, unstow the SABB, jettison the covers for the SSU and ECU, and release the PVR.

Swanson and Acaba would make the second EVA, to prepare some batteries on P6 for a task on 2JA, and to deploy the P3 UCCAS and S3 outboard zenith PAS payload attach systems,. The P1/P3 fluid jumpers would be worked on.

On EVA 3, Arnold and Acaba would relocate the CETA carts, repair the SPDM and lube LEE B, replace an RPCM power module. Then, they would move to S1 and reconfigure panels, jumpers and clamps on S1.

EVA 4 (Swanson and Arnold) would see the JLP GPS antenna installation, work on the Z1 path panel, and deploy of the S3 outboard nadir and inboard zenith PAS systems.
