On Earth, buoyancy-driven convection and sedimentation govern how melts mix, how crystals nucleate, and how glass solidifies. They impose striations, uneven particle distributions, and defects that cap what the most valuable materials can become. Remove gravity and transport becomes diffusion-dominated, the process runs under control the ground can't offer.
One integrated system. Repeatable cadence. Built for recurring campaigns, not a single flight.
Your feedstock launches aboard a resupply capsule and is transferred to a dedicated processing bay aboard Tessera-1.
Your process hardware runs continuously in microgravity, power, thermal control, and telemetry handled by the station.
Finished material returns in a controlled reentry capsule, straight to your facility, chain of custody intact.
No sedimentation, homogeneous, monomodal particle and phase distributions.
No buoyancy-driven convection, diffusion-limited transport: fewer striations, more uniform crystal and melt composition.
No hydrostatic pressure, larger unsupported melt zones and containerless processing, free of container contamination.
Crystalline suspensions for high-concentration subcutaneous formulations, and larger crystals for structure-based drug design.
Bulk single crystals with reduced dopant striations and lower dislocation density, for substrate and device-material research.
Fluoride (ZBLAN) glass drawn without gravity-induced crystallites, plus immiscible alloys and containerless melts.
The science is validated. The bottleneck is access.
Merck. Crystallized pembrolizumab (Keytruda) aboard the ISS. Microgravity produced homogeneous ~39 μm crystalline suspensions where matched ground controls produced an uneven bimodal 13/102 μm mix, informing a crystalline-suspension approach for high-concentration biologics.

Fifty years of melt growth. Across Si, Ge, GaAs, GaSb, and InAsSb, suppressing buoyancy-driven convection consistently yields fewer dopant striations, lower dislocation density, and better compositional uniformity, recently a tenfold dislocation reduction in space-grown InAsSb. (npj Microgravity meta-analysis, 2024; InAsSb, 2026)
Flawless Photonics. Drew roughly 11 km of ZBLAN fluoride-glass fiber aboard the ISS in 2024, the first commercially relevant fiber lengths produced in orbit, targeting the ultra-low attenuation that microcrystal defects prevent on the ground. (2024)
A crystal, a glass, or a doped ingot that survives orbit but not reentry is worthless. Our reentry vehicles are built around the payload, thermal isolation, containment, and precision landing that return your material with its structure intact: crystal form, glass phase, and dopant profile preserved, chain of custody documented.
Downmass is the product. We engineered the entire path to protect it.
