re: The James Webb Space Telescope
Raoul,
Thanks for the link to the JWST Observatory. I see that JWST will be positioned at earth / sun L2 so as to be shaded from the sun and for easy station keeping. I see that JWST does have solar panels. Also the largest feature of JWST is a sun shield. That got me to thinking... How much earth shade will it get at L2? Is it that the apparent diameter of the earth is relatively small compared to the diameter of the sun from L2?
Thanks,
Tom C.
