Tweet is kind of clickbaity. Unless they can transmit data faster than the speed of light, you still are going to have around a 13ish minute delay each way, so there is no “instant communication”

That being said, having a more robust means of data transmission would be nice for both manned and unmanned missions
I thought the same thing , and didn't even click it. Stupid old physics messing up all their plans.

It's just an upgrade for the same ole really.

I'm curious what we will implement for a fixed system in the future, still early for any real plans now. Our mission based systems won't be effective for a colony, especially more than one.

I've always imagined some kind of high intensity laser array on each, with repeaters to account for orbits, basically the wireless point of a giant fibre cable, but I'm sure there's a smarter way.

You're going to need a local proxy on Mars for data heavy stuff like video streaming because any Earth-Mars link is going to have limited capacity and (when the planets are on the opposite side of the Sun) over 20 minutes of latency. Early on it's probably cheapest to just ship physical media when it comes to stuff the size of Netflix libraries.

M74 is a large spiral galaxy 32 million light years from earth.

This is the result of 924 10 second exposures stacked and processed using Siril, Starnet ++, & GraXpert. Captured by a ZWO Seestar S50.

Funny thing about this one, in one of the 10 second stacks and airplane flew right through the picture, and now it's gone!

This is from a weather radar an hour ago. What are we looking at here? The trail is 200km/124 miles long. Radar images are 5 minutes apart, and it doesn't show before or after this one. Is it Musk sending a Tesla in orbit? It is Bitcoin going to the moon? A plane? A bird? Looks pretty cool anyways.
