Telstra has revealed the addition of almost one million new mobile services in the six months to December 2011, but Sensis revenues plummeted 24 percent in 12 months.
The objectives of the test were accomplished according to NASA officials; that is, “to resolve differences in heritage turbopump performance data and recent component-level tests, and investigate vibration and pressure drops through the turbopump inlet ducts.” [NASA: “NASA Successfully Completes First Series of Ares Engine Tests”]
Mike Kynard (NASA manager of the upper stage engine for the Ares Project at NASA’s Marshall Space Flight Center in Huntsville, Alabama) stated, “This series of tests is an important step in development of the J-2X engine. We started with a number of objectives and questions we needed answers to as we work to complete designs of the J-2X engine. The data we have gained will be invaluable as we continue the design process." [NASA: “NASA Successfully Completes First Series of Ares Engine Tests”]
The J-2X is in the early developmental stage. The data collected from these tests will help to further refine the design of the pump, gas generator components, and other engine components of the new Ares J-2X rocket engine.
Further tests will be run in the future to gain additional information to be used in the development and eventually construction of the J-2X rocket by Pratt and Whitney Rocketdyne Inc., which is based out of Canoga Park, California.
One of the next tasks for the team at the Stennis Space Center is to modify the A-1 Test Stand in preparation for the test of the upgraded powerpack, now scheduled for early in 2010.
