In order to restore STIS to operational status, astronauts will perform a never-before-attempted on-orbit replacement of an electronics board inside STIS’s main electronics box. On Earth this operation is relatively simple, but in space many challenges confront the astronauts as they work to replace the failed board including working to remove 111 tiny, non-captive screws with astronaut gloves.
