- uguuo_o 3y agoYes, new seal designs have been proposed and prototyped over the years. As far as I know, so take it with a huge grain of salt, no particular design is as of yet hailed as the solution to this problem. There have been multiple NASA technical briefings on the subject since Apollo, with the last one I have seen just a few years ago. These take into account all known solutions proposed by industry and NASA, and the problem just seems to get worse the more we learn about lunar regolith and the lunar environment.
