Interorbital Systems was selected as the recipient of the NASA Small Business Innovation Research contract for its program, NEPTUNE Modular Rockets for Breakthrough Low-cost Space Access. SBIR contracts are granted to fund the research, development, and demonstration of innovative technologies that NASA selects for their potential commercial applications.
IOS will use the funding to further develop the NEPTUNE rocket series, which will be the cheapest orbital launch vehicle available. The NEPTUNE is designed to be a simple rocket built from off-the-shelf components and consisting of multiple Common Propulsion Modules, or CPMs, for mission flexibility. Its low price will help make orbital research and commercial development platforms more widely available to academia, businesses, and private individuals alike.
