One may thing that flat satellites can only be good for communication. However, if make some research on flat telescopes we can find designs that can be implemented on a foldable satellite.
The Modified Dall–Kirkham telescope uses an elliptical primary and spherical secondary mirror as in the conventional Dall-Kirkham configuration, but also includes a lens group ahead of the focal point to improve off-axis image quality.
This design can be enhanced to be deployed on a foldable satellite. The result would resemble a Loupe. That’s why I called it a Space Loupe. I thought of this design mainly for earth surveillance applications. Where the source is way brighter than the location of the satellite in orbit. Negating the need for light blocking exterior and simplify the design. This design can also be used to observe the Moon and the Solar System which have higher brightness levels and require less magnification. Having more telescopes that cost less and easy to maintain has some potential besides the sophisticated ones. More observation points are obviously beneficial for the science and the national security.
