Mission 001Destination Mars

A second home for humanity.

MarsFirst exists to move humanity towards life away from Earth. We start with Mars, and we start now, with work that compounds.

Why Mars
01Why

Not a flag and footprints, but a place where people *live,* build and raise the next generation. A second home makes humanity *resilient.*

Why Mars, and why first.

It's the nearest world where a self-sustaining city is plausible: a day almost exactly like ours, water locked in ice, and enough sunlight to work with. Hard, not impossible. That's the right kind of problem.

  • Length of day24h 39m per sol
  • Surface gravity0.38 g
  • Year687 Earth days
  • WaterPolar caps & subsurface ice
  • Transfer window~26 months
02Principles

How we move.

A few rules we hold ourselves to. They matter more than any single plan.

01

Mars first

One destination, chosen on purpose. Focus is how hard things actually get done.

02

Build what compounds

We ship useful products today. Each one funds the next and sharpens the engineering culture the long mission needs.

03

A long horizon

Decades, not quarters. We'd rather be careful and early than loud and late.

03The long road

Decades, not quarters.

Getting people to another world, and keeping them there, is the work of a generation. We'd rather be careful and early than loud and late.

So we build in the open where we can, quietly where we must, and always toward the same destination.

The road, roughly

  • NowBuild useful things that sharpen the craft and fund the next step.
  • NextGather the people and the knowledge a long mission needs.
  • ThenGo. Mars first, and further after that.
