|What's Going on Here?|
|Loading below is a close-up photograph of the door to the HST instrument bay taken during the February 1997 repair mission. Next to the door is an informative plaque with instructions for opening the doors. The plaque says:|
1. RETRACT SEALS BEFORE
(TURN ADJ. SCREWS CW)
2. EXTEND SEALS BEFORE
(TURN ADJ. SCREWS CCW)
|The background on this page is a Hubble deep field image from 276 exposures taken over 10 days.|
A visitor writes:
CW or CCW aside, the first step says to retract the seals before opening. The second step says to extend the seals before closing.
Shouldn't it say extend seals AFTER closing????
I believe when they went back to the telescope to make repairs, they could not get this door to close properly. Maybe these instructions were the problem!
