This was from the SpaceX + T-Mobile Update a few minutes ago but it is not the main message for today.
We would love to have T-Mobile on Mars.

SpaceX + T-Mobile Update
The real message wasn’t quite as cool, but it was still awesome stuff.
Sometime late next your existing T-Mobile phone will have messaging (not necessarily voice or data until later) connectivity anywhere in the lower 48 states, Hawaii, Puerto Rico, large portions of Alaska, and wide areas of U.S. territorial waters.
The vision is no more cell phone dead zones. Emergency services in your most remote areas anywhere in the country and eventually the entire world. The price? Free for most existing T-Mobile service plans.
There were some interesting technical problems which had to be solved. It works in the lab and they are confident it will work in the real world.
Among the problems are:
- The satellites are traveling at 17,000 MPH and compensated for the doppler effect is required.
- The satellites are 50 miles away and the satellite antennas need to be about five meters by five meters to receive and transmits signals to the cell phone antennas.
- Because of the larger antennas they plan to use SpaceX Starships rather than Falcon 9s..
I love living in the future.
