Summary
[edit]DescriptionInstallation of a Test Mirror on the Test Backplane (14742758940).jpg |
In preparation for flight hardware, engineers and technicians at NASA Goddard are installing our engineering design unit (EDU) mirror onto the pathfinder backplane. The pathfinder is a test version of the backplane, which is the spine of the telescope, supporting the mirrors and instruments. The EDU is a gold-coated flight spare mirror. Though here it has a cover on it to protect it. A robot arm is being used to move the mirror over the backplane and to aid in installation.
