TERRIERS Integration

This is a pictorial flow of the TERRIERS integration. Each picture has a link to the original image if one wants a better look.

TERRIERS integration and launch are taking place at Vandenberg AFB. We integrated TERRIERS in building 1555, which is about 1/4 mile from the Pacific Ocean.
TERRIERS arrived safely on March 19th and was set up in a clean room in the east bay of Building 1555 next to the vehicle. The ground support equipment (GSE) was set up and the cables were routed from the payload control room to the spacecraft.
The next day we installed the A patch antenna and started the post ship functional test.
March 20-24 we worked through problems with the GSE and complete the functional test. The spacecraft all is functioning nominally.
At the same time, MUBLCOM and the vehicle were also nearing readiness for our first combined test.
Flight Simulation 3 was run on March 24th and the data was reviewed the following day. Also, we incorporated the strip charts into the arming and recycling procedures.
The data from Flight Sim. #3 reveals that MUBLCOM has a problem with coupling between cables. After two tries and a week the problem is finally resolved.
During the MUBLCOM cable rework, we continued testing and we tipped the spacecraft to prepare for spacecraft mate.
On April 2 MUBLCOM and the Payload Adapter Fitting (PAF) cone is mounted onto MUBLCOM.
The following day, April 3, we successfully mated TERRIERS to the Pegasus.
The next day we performed Flight Sim #4 without any problems. The next couple of days we did our final checkouts and prepared for fairing installation.
On April 9, it is announced that an anomaly on WIRE cannot be resolved and we must stand down until it is. It turns out this takes about 3 weeks. In the mean time, the integration crew starts working hard on finding things to do.
While waiting, the crew gets a VIP view of the Landsat 7 launch aboard a Delta II on April 15th and plenty of time to watch the California sunsets.
