U.S.-based TGV Rockets has completed test firings of a 30,000-pound-class throttleable rocket engine that uses JP-8 kerosene fuel. The first phase of testing was conducted over the past two months at NASA’s Stennis Space Center in Mississippi. The second phase, focused on gaining more information on the performance of the JP-8 fuel, is under way.

The company expects it will one day be able to facilitate the shuttling of equipment and sensor payloads on quick-turnaround suborbital missions for the military and to help reduce the cost of geospatial imagery.
