这个可以有

【在 ihiker 的大作中提到: 】
: There are, however, modest efforts being made to make JWST “serviceable” like Hubble, according to Scott Willoughby, JWST’s program manager at Northrop Grumman Aerospace Systems in Redondo Beach, California. The aerospace firm is NASA’s prime contractor to develop and integrate JWST, and has been tasked with provisioning for a “launch vehicle interface ring” on the telescope that could be “grasped by something,” whether astronaut or remotely operated robot, Willoughby says. If a spacecraft were sent out to L2 to dock with JWST, it could then attempt repairs—or, if the observatory is well-functioning, simply top off its fuel tank to extend its life.
: 错。JWST已经预留飞船对接接口，可供维修和补充燃料。理论上重型猎鹰或星舰都能完成这项任务。

重型猎鹰和星舰受累于比冲低，都不适合高轨任务

镜头盖开了没有？

深空运能取决于delta V而不是比冲

低比冲意味着高G或者多级，技术上不可行
