Awesome link. Thanks for posting. I'm wondering, does anyone know why we didn't send JWST to L4 or L5, where (as mentioned in the link above) it could remain orbiting indefinitely without the need for fuel? Is it because those points are a lot harder to get a spacecraft to?
- jffry 5y agoJWST is making observations in orange to mid-infrared wavelengths. The sun, earth, and moon are all quite hot and emit a lot of light in that range of wavelengths. Near L2, JWST can use one sunshield to block out light from all three bodies, with less impact on what portion of the sky it can observe
