I'm not going to link to the sweary Jalopnik article, which I think overplays it a scootch but...
... some recent Tweets from Captain Spaceism do seem to suggest he doesn't big physics well. It revolves around the proposed "Marslink" concept, which essentially aims to put communications satellites in orbit around Mars in order to ruin its night sky too provide support for future ground and orbital missions as well as imaging the planet's surface.
One thing he's definitely said is that it will need "petabit/sec" speed (he means bandwidth), which is currently not even a thing commercially on Earth. We're close - about halfway there - and some experimental techniques have resulted in actually more than that, but all require cable and not satellites. I'm assuming he's thinking there's some magical solution with lasers, but the bandwidth record there is three and a half orders of magnitude out...
The other, which Jalopnik has quoted but I can't easily find, is that he's suggested a series of satellites between the two planets to provide a data bridge; Jalopnik says this shows he doesn't understand the fundamental limitation of data speed but he's kicked off at that notion and stated it'd help with bandwidth... which it wouldn't necessarily.
It would help with data integrity, but either way it's an idea he's nicked from Stargate SG-1/Atlantis and the McKay-Carter Intergalactic Gate Bridge which benefitted from being both fictional and taking place at locations spread over significantly larger distances which remain almost stationary with regards to direction relative to one another and not Earth and Mars which can be 35 million miles apart or 250 and have a whole-ass star in the way, and this varies from one extreme to the other every 13 months or so...
