The SpaceX team just completed the first post on X from a phone to one of our Direct to Cell satellites!
This was the tree cover in a small valley in the Santa Cruz Mountains earlier in the day when we were exchanging some DMs on X.
This post was sent through a SpaceX Direct to Cell satellite in space 🛰️

It feels very surreal that the team is now walking around the SpaceX campus texting each other from our off the shelf, and unmodified, test phones sending normal 4G LTE data packets up to our first 6 satellites and back down to the other test phones.
The SpaceX Direct to Cell team has really been sprinting. So nice to be a part of this group and working hand in hand with our US partner, T-Mobile.

Perhaps your initial difference of opinion is based on some different data? This is what I’m tracking for data rates (single beam, beam center, demo from space).

We really thought about it. The dtc payload is just such a beast, that it takes up the whole belly of the sat plus a large deployable, and it uses the same power as the broadband payload.

We were once serious (energy and climate) people. Hopefully we return to this mindset soon enough. Perhaps data centers for AI will demand/drive the next large scale energy wave.
Perhaps the best thing for advancing clean / energy independence and the use of nuclear energy
