Redwire Corporation, a leader in space infrastructure for the next generation space economy, announced the first sale of its space-manufactured optical crystal to researchers at the Center for Electron Microscopy and Analysis (CEMAS), a leading electron microscopy facility, at The Ohio State University. The transaction recorded two grams of space-manufactured crystal were sold to Ohio State. Based on the sample size sold, the space-manufactured crystals have an approximate value of $2 million per kilogram.
“This is an exciting milestone that validates our commercialization plan for manufacturing space-enabled products in low-Earth orbit and further stimulates demand for in-space production”
The space-enabled optical crystal was manufactured in Redwire’s Industrial Crystallization Facility (ICF) onboard the International Space Station (ISS). This transaction marks the first time that a space-enabled materials product has been sold on Earth—a significant milestone for space commercialization and a demand signal for Redwire’s space-based manufacturing.

Space-manufactured optical crystals could provide significant improvements to high-power, large laser systems used on Earth. The high-energy laser market is seeing strong growth with an increasing number of terrestrial applications from advanced manufacturing and machining to weapons systems. These laser systems are enabled by high efficiency laser lenses that are produced using optical crystals.
Currently, optical crystals manufactured on Earth have lower damage thresholds due to gravity-induced inclusions and defects which limits the output of high-power laser systems since the lenses are subjected to laser-induced damage. Space-manufactured optical crystals could improve system performance because they have a higher laser damage threshold due to fewer inclusions and defects because of the space manufacturing process.
“This is an exciting milestone that validates our commercialization plan for manufacturing space-enabled products in low-Earth orbit and further stimulates demand for in-space production,” said Andrew Rush, Redwire’s President and COO. “This is a watershed moment for space commercialization. While we are continuing to refine production techniques for a variety of products, we are now expanding our focus beyond pathfinder demonstrations to increasing production of space-enabled products sustainably, profitably, and at scale. Redwire’s orbital factory is open for business, and we are expanding our on-orbit capabilities to serve new markets.”
