Asteryx Space — Orbital Microgravity, Made Easy

01 / SERVICES

MICROGRAVITY SERVICES

Orbital conditions,
impossible to reproduce on Earth.

24UPayload Return Capacity

Designed to return up to 24 units of payload from Low Earth Orbit, our platform enables access to manufacturing and research conditions that simply cannot be reproduced under gravity.

01

Pharmaceutical crystal growth

Larger, higher-purity protein crystals for next-generation drug discovery and structural biology.

02

High-purity materials & alloys

Convection-free solidification yields metallic structures and composites unattainable on Earth.

03

Orbital biotechnology

Cell cultures, tissue engineering and stem-cell research in a sustained microgravity environment.

04

Next-gen optical fibers

ZBLAN fibers drawn in microgravity exhibit orders-of-magnitude lower attenuation than Earth-made.

05

In-space manufacturing

From semiconductors to ceramics — production processes that benefit from sustained zero-g.

06

Technology demonstrations

Validate hardware, components and processes in a real orbital environment before scaling.

02 / WHY Asteryx

PASSIVE REENTRY ARCHITECTURE

Asteryx is a naturally stable lifting body — capable of passive reentry without active control systems, combining the simplicity of a capsule with the aerodynamic benefits of a winged body.

VS. CLASSICAL LIFTING BODY / SPACE PLANE

Simpler. Lighter. More reliable.

No RCS, no aerodynamic control surfaces, no actuators or guidance algorithms
More available weight and volume for payload
More reliable — fewer failure modes thanks to architectural simplicity
Reduced development time and cost
Fewer certification and flight authorization challenges
Lower insurance costs across the lifecycle

VS. CAPSULE

Reusable. Gentler. Smarter volume.

Reusable across many flights
Smaller reentry decelerations — friendlier to fragile payloads
Better internal volume occupancy efficiency
Architecture upgradeable to a controlled vehicle (not currently in roadmap)

03 / THE VEHICLE

Asteryx · TECHNICAL DATA

Built around one idea: stay stable, come home.

A 1.2-meter passive reentry lifting body. No reaction control, no aerodynamic surfaces — just a shape that flies itself through atmospheric entry by design.
