Nov-Dec will be the next launch window for Mars.
There needs to be a Mars-orbit-then-return mission of some sort, also it wouldn’t hurt a thing for SpaceX to deploy at least three of the new version Starlink satellites around Mars with a laser comm station (or more than one) to keep an active (though obviously time-delayed) comm link between Mars and Earth.
NASA might even be interested in piggybacking relays for the existing surface rovers and such to improve links to and from those.

There is a YouTube channel that does nothing but show what musk is posting. Last night there was a huge discussion of the space economy that musk envisions. I barely understood it. Some use of solar to power data centers and such. There was talk of using starlink for distributed power in the same way as Tesla cars might be used for distributed compute.
Generally Tesla stock looks like it can easily 10x over the coming years.
