NASA has started full-engine, hot-fire testing of the low-cost Fastrac rocket engine at its Marshall spaceflight centre in Huntsville, Alabama, with a 20s full-power test to demonstrate the operation of the complete engine system. Up to 84 engine test firings are planned this year. The 45,000lb-thrust (200kN) Fastrac will be used to power the Orbital Sciences X-34 technology demonstrator.
