With facilities in Houston, TX, Alexandria VA and the Silicon Valley, Nanoracks initially worked with NASA to contract for no-cost laboratory research space on the ISS. The firm signed a contract with NASA in September 2009 and had their first laboratory on the Space Station in April 2010. Since 2010 NanoRacks has designed and built all 36 of the modular labs for the U.S. National Laboratory on the Space Station.

Facilities and labs Low-Earth orbit facilities NanoRacks facilities on the International Space Station (ISS) include: NanoRacks Platforms include both standard space-capable lab racks to provide power and data transfer capabilities as well as CubeLabs Modules experimental platforms. Several standard rack sizes are available to accommodate nanoscale research in microgravity experiments that require various amounts of rack volume.
