Why Microgravity for Biologics?

What if your biologics could be delivered as a simple self-injection instead of an hours-long IV infusion?

On Earth, gravity drives sedimentation and convection that distort crystal growth, create heterogeneous particle sizes, and limit the concentration at which biologics remain stable in solution. In microgravity, these forces are significantly reduced, resulting in crystals forming with greater uniformity, higher purity, and more predictable particle size distributions.

This enables concentrated formulations that improve patient care, reduce clinical burden, and transform how your drug reaches patients

Two scientists working inside a spacecraft or space station module, with Earth seen through a large circular window. One scientist is examining a small clear plastic container, while the other is holding a tablet or data device.

01 - Terrestrial Challenge

High-concentration biologics face stability, viscosity, aggregation, and delivery constraints that limit formulation options and patient convenience

02 - Microgravity experiment

Low-shear, buoyancy-free conditions can support cleaner observation of crystallization and formulation behavior

03 - Actionable Insights

Experiment outputs inform crystal form, stability strategy, delivery route, and formulation decision

04 - Patient Impact Goal

Enable easier administration, stronger shelf-life strategy, and scalable Earth-based manufacturing, moving biologics from lab discovery to patient reality
