How to connect Earth and Mars with an internet link?
Here is a quick explanation of my Marslink simulation (v3).
Design your own interplanetary network and find out the total Mbps, latency and cost!
I'm pretty sure @SpaceX will deploy a version of this one day.

A massive effort to sequence the DNA of Vikings across Europe was published in 2020. The study revealed family histories of Vikings who set forth—and died—far from home.

Although I'm super bullish on SpaceX and I ran the numbers, I am baffled by 1M people on Mars by 2035-2040.
This would be absolutely mind blowing.
The only thing that tells me it might actually happen is Elon's comp package that requires it.
Which in itself is mind blowing.

Key Gwynne insights from this…
- no top number for Starlink sats. (Despite what others might say)
- capacity constrained in several key markets.
- flight 15 may be first Florida launch.
- we will not sell compute that we need for our internal AI.
- there will be likely more M&A particularly in AI (in general and SpaceX)
- Elon the best CEO now maybe ever.
- 1M inhabitants on Mars by 2035-2040.

Happy @SpaceX day for those who celebrate!
(We left our Starship torch in Europe - not allowed on the plane!)

Time to celebrate SpaceX IPO with some s'mares.
Those are Mars s'mores, made with Starship-flamed Marsmallows!

Probably a good day to pop a Mars-themed champagne bottle!
I'll keep one for the first successful landing of SpaceX on the red planet.
Such a glorious day!!

Here's what @SpaceMatthieu found while building our SpaceX valuation model.

We've been building this for months with @julienvm at @dynamikorbits: a full interactive model of the SpaceX business, ahead of the IPO.
The most valuable part for me was being forced to understand how this company actually works.

We finally released our SpaceX model! 🚀🛰️
This helps calculate the estimated company value and share price based on your assumptions.

We do have a Monte Carlo analysis, which does the slider work for you.

I'd love to hear your thoughts! Thanks!
We built this at @dynamikorbits.
This is @SpaceMatthieu and myself.

This is probably the best look at the shockwaves I’ve seen from the latest Starship flight.
Captured from a GoPro I clamped onto a proper camera to record simultaneous video. (I’ll show you the photo the better camera took in the reply)
