A RIDE HOME FOR RESEARCH

Getting to spacegot easier.Coming backis still hard.

Zavity is building Gravion, a small capsule designed to bring experiments back from orbit, so what we learn in space can be used on Earth.

SCROLL TO COME HOME

01 — WHY SPACE

Take gravity away, and things behave differently.

On Earth, heavy particles sink and warm liquids churn. In orbit, that stops. Crystals, materials and living cells can form and grow in ways that are hard to reproduce on the ground.

MEDICINES

Drug crystals can grow more evenly, helping scientists understand how medicines form.

↗

MATERIALS

Metals, glass and semiconductor materials can mix and set more uniformly.

↗

LIFE SCIENCES

Cells and tissues can behave differently, revealing biology that's hard to see on Earth.

TRY THE SCIENCE

Small changes. Molecular possibilities.

Explore how growing a crystal connects to understanding a protein — and how that knowledge can guide medicine research.

THE PROTEIN CRYSTAL LAB01 / 02

Give a crystal room to grow.

Same protein. Different environment. Compare two illustrations of crystal growth.

ON EARTH · GRAVITY AT WORK

Settling and buoyancy-driven flow can affect crystal growth. This example shows crystals with more variation in size and orientation.

Illustrative comparison, not measured data. Results depend on the protein and growth conditions; Earth-grown crystals can also be high quality.

THE MEDICINE MATCH02 / 02

Find a molecular fit.

Explore a protein’s binding pocket. Try two candidate shapes and see what changes.

PROTEIN TARGETCANDIDATE MOLECULE

CANDIDATE A · SHAPE MISMATCH

This candidate does not fit the illustrated pocket. Studying a protein’s structure helps researchers explore other molecular shapes.

A shape analogy, not a molecular simulation. Fictional protein and candidates; the dashed lines illustrate possible interactions.

But the science has to come home.

Most experiments need to be back in a lab on Earth to be studied.

02 — GRAVION

Meet Gravion.

A small capsule designed to carry experiments to orbit and bring them safely back to Earth.

DRAG TO TURN

03 — THE RETURN · HOW IT'S DESIGNED TO WORK

ORBIT

ORBIT

Turn for home.

When the experiment is done, Gravion leaves orbit and points its heat shield at Earth.

ATMOSPHERE

Through the fire.

Air turns to glowing plasma around the capsule. The heat shield takes the heat and protects the experiments inside.

DESCENT

Slow down.

Once the fire is over, parachutes open and the capsule drifts down.

HOME

Back in the lab.

The capsule is recovered and the experiments go back to the scientists who sent them.

04 — WHY NOW

Research in orbit needs a ride home.

Getting to orbit has opened up.

Shared rides on rockets have made it far easier to send small experiments to space.

Space research is on the move.

The International Space Station, home to much of today's orbital research, is planned to retire after 2030. That research will need new ways up and back.
