Tierra 2026 is part of the Mars Challenge horizon: looking at a challenge from a broad perspective to ask what can change here, on our planet.
It connects with Earth-Back Thinking™: imagine from Mars to act on Earth.
A journey to be confirmed
Tierra 2026 content, conditions and participation arrangements will be communicated only through the edition’s official channels and rules. This page does not anticipate challenges, formats, requirements or results that have not been validated.
Thinking about return to Earth
In Mars Challenge, a proposal does not remain in the fiction of another planet. It asks how an idea, technology, decision or way of collaborating could help people and communities on Earth.
It means asking what problem we need to understand, who a solution may affect, what consequences and limits matter, and how to explain its value responsibly.
Imagining far away can help us care better for what is close.
Confirmed Tierra 2026 information and its connection to The Grand Jam will be published here when available.
