The ESS team has access to all of the historical telemetry data from Hubble since deployment in 1990. They have the ability to retrieve and plot voltages, temperatures, currents, speeds, torques, switch positions, and other values. The Anomaly Response Manager team is called into action to resolve problems which arise during the mission. They act as systems engineering to coordinate a multidisciplinary analysis and response for any trouble. A servicing mission requires the coordination of hundreds of engineers and controllers, two spacecraft, communications relay satellites, and astronauts.
Training is key to ensuring mission success.
The year leading up to the mission is spent simulating the mission. The simulation team crafts clever failures to present to the operations teams. The team at the DOC operates all of the computer equipment which processes Hubble's data and prepares commands. The HST network is essential to tie together all the control computers. The network team had assembled a high speed, high reliability network to fulfill the servicing mission requirements.
