Simulated repair of the right dexterous elbow using the engineering arm and an astronaut15 October 2002 In a simulation of the ability of Ranger to help service itself in space, the engineering arm was used to loosen the bolt that helps hold the right elbow to the right shoulder. A person, simulating the motion of an astronaut, was then able to pull the elbow free from the shoulder. This process is shown in the video clip below.

Handoff of a Hubble Space Telescope Fine Guidance Sensor handhold15 October 2002 One of the tasks planned for the next Hubble Space Telescope (HST) servicing mission is the changeout of one of HST's three fine guidance sensors (FGS). After a handhold is installed on the FGS by the astronauts, the handhold is used to guide the FGS along guide rails and out of the telescope. The FGS is then temporarily stowed on the aft fixture. The following photos and video show a handoff of the FGS handhold from a simulated astronaut to Ranger and back again.
Right dexterous shoulder and elbow first motion11 October 2002 The shoulder and elbow of the right dexterous arm moved today for the first time using 1553. After some small configuration issues, all DOFs where moved under power with no problems. Props go to Kiwi for building reliable software, and Wendy for nice soldering.
Simulated Hubble Space Telescope Electronics Control Unit task8 October 2002 An inexperienced user changed their first electronics control unit (ECU) today, in under 18 minutes. This did not include an end effector changeout, but did accomplish the traversal time for one changeout. Not bad for a beginner. Below is a picture taken during the task.
