I'm also working the planetary sunshade. Any source for the Chinese $60T price point?

  This paper describes a sunshade launched from a large expendable rocket of current technology https://journals.sagepub.com/doi/full/10.1177/1687814017719227 https://journals.sagepub.com/doi/full/10.1177/16878140177192... The $60T is my number based on the guess that the Long March 5 costs about the same as similar western rockets.
