- Ball Aerospace is making costar, and it's a prety interesting instrument.
-
- it's essentially three little mirrors on a sliding arm on a giant optical
- bench (phone booth sized). each of the little mirrors is calibrated
- to adjust each of the intruments.
-
- now here is my question.
-
- why not design costar to also add filters. given wf/pcs aversion
- to the moon and sun, if you put a filtering mirror in also, could
- you then conduct really hi res lunar imaging? or is this just pointless
- cuz we already have more then enough capacity.
-
- also if you can put in filters, i think you could reduce the cone of avoidance
- around both the sun and moon, filters on, slew aroundthe sun to target
- filters off. i would think simpler and easier then the complex
- pirouette they do now and safe rthen closing the main aperture door.
