Redwire Wins ISS Greenhouse Contract as Shares Jump

The award will test a microbial biostimulant to grow wild strawberries in orbit, a step toward regenerative space agriculture and longer‑duration life‑support research.

Overview

  • Redwire announced a contract with Astrobiome Space on June 4 to fly its commercial Greenhouse on the International Space Station to grow wild strawberries and test Astrobiome’s microbial soil enhancer.
  • The contract is the inaugural flight for Redwire’s Greenhouse platform and Astrobiome will begin Earth‑based tests before the scheduled ISS experiment.
  • Redwire’s stock climbed roughly 16–18% intraday after the announcement, a move market reports say may have been amplified by about 17.96% short interest that created conditions for short covering.
  • The deal adds to recent technical and defense wins for Redwire even as analysts warn the company remains unprofitable, has grown through dilutive acquisitions, and faces valuation pressure after a recent Jefferies downgrade.
  • Beyond the immediate market reaction, the experiment advances practical work on growing fresh food and testing life‑support enhancers in microgravity, which could inform future long‑duration missions and commercial payload demand for Redwire’s systems.
