NASA has started full-engine hot-fire testing of the low-cost Fastrac rocket engine at its Marshall Space Flight Center at 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 210,000lb-thrust (935kN) Fastrac will be used to power Orbital Sciences' X-34 technology demonstrator.
