The Marker

Earth Signs Its Name.

The Eternal Marker is a flight artifact carrying the signatures of people around the world who chose to help build humanity's planetary defense future. The original marker will travel aboard the Unity Lander to asteroid Apophis.

Museum-quality editions will remain on Earth, allowing future generations to search, discover, and remember the names of those who helped begin the planetary defense era.

The Eternal Marker — a tall etched gold monument in a darkened museum hall

Concept rendering. The Eternal Marker is a museum-grade flight artifact engraved with public signatures.

The Vehicle

The Unity Lander

The Unity Lander is a flight spacecraft that will journey to the asteroid Apophis, one of the most significant near-Earth asteroid encounters in modern history.

Flying aboard a mothership, Unity will carry the Eternal Marker, a remarkable work of art etched with the names and signatures of supporters from around the world.

Unity will deliver the Eternal Marker to the surface of Apophis as humanity claims its place in the stars. Apophis is the Egyptian deity of chaos and uncreation. Our civilization will meet it with unity, beauty, and art, proving that we are creators of our own destiny.

The Shield

Impacts are Fate.Protection is Choice.

For billions of years, Earth could only endure what came from above. The next chapter should be different. Planetary defense is the work of finding, understanding, and responding to hazardous celestial objects before they become catastrophic threats.

The Architecture

Creating a Shield for Gaia

Four systems stand between Earth and the next impact.

System 01

Planetary Defense

Early Detection

Finding dangerous objects before they find us.

System 02

Planetary Defense

Characterization

Understanding their size, composition, orbit, and threat.

System 03

Planetary Defense

Response

Rapid deployment of missions to investigate, assess, and intercept.

System 04

Planetary Defense

Protection

Diversion, capture, and control systems capable of safeguarding Earth.

One planet. One species. One Shield.We are Gaia United.
