NASA's National Aeronautics and Space Administration (NASA) is seeking to procure the Hydroponic/Aeroponic Nutrient Delivery In Volumetrically Efficient Garden (HANDIVEG) system, which is intended for use in growing space crops aboard the International Space Station (ISS) as part of a continuous crop production demonstration. The procurement involves the final design, documentation, fabrication, and delivery of flight-ready HANDIVEG hardware, which will integrate with NASA’s Ohalo III test rig. This technology, initially developed by Sierra Space Corp (SSC) under a NASA Research Grant, requires specialized expertise that SSC possesses, making them the only responsible source for this contract. Interested organizations may submit their capabilities and qualifications to Tammy Clark at tammy.k.clark@nasa.gov by 2:00 PM ET on December 31, 2025, for consideration in determining whether to conduct a competitive acquisition process.
