Marslink Relay Network
A chain of relay satellites between Earth and Mars: constellation shapes, throughput and deployment cost, in an interactive simulator by Julien Villa-Massone.
Studies of Mars communications and space economics. Each one comes with its models, its results and an interactive simulator, so you can see where every number comes from.
Each programme is a study plus a simulator. The simulator shows the study's published numbers. It does not invent its own.
Two ways to build the Earth–Mars data link, a relay chain and direct clusters, studied side by side, next to a long-term model and valuation of the SpaceX ecosystem.

A chain of relay satellites between Earth and Mars: constellation shapes, throughput and deployment cost, in an interactive simulator by Julien Villa-Massone.

Small laser terminals flying in clusters at each planet, combined into one direct optical link. The simulator shows the study's numbers: fleet size, orbits, formations and deployment cost.

A model of the entire SpaceX ecosystem: launch, Starlink broadband, direct-to-cell and orbital compute, projected into the long-term future, with a valuation you can adjust and explore.
