Propulsion: Work continues on E-1

Work continues at NASA's John Stennis Space Center to prepare the E-1 Test Stand for testing the AJ26 rocket engine that Orbital Sciences Corporation will use to power commercial transport flights to the International Space Station. Last month, 6,500 gallons of rocket propellant fuel was delivered to the test complex. The fuel will be used for testing the AJ26 engines beginning this summer. NASA has partnered with Orbital to provide ISS servicing flights through the agency's Commercial Orbital Transportation Services initiative. (Source: Lagniappe, April 2010)
