Virgin's SpaceShipTwo Gets Green Light for Powered Tests

Beth, it's unlikely that Scaled Composites is still at the stage of testing aerodynamics, especially since there were predecessor prototypes for both the spaceship, SpaceShipOne, and the launch vehicle, WhiteKnightOne. As naperlou says, these new tests are to ensure it can fly under power.
You may be correct about the CFD processing going on Beth, but these guys may also be at the stage where they just need to light off rockets and see if they can avoid blowing up.
It is good to see the commercial space business making progress. With SpaceX and Virgin Galactic making progress we can finally get the government out of this. I worked for many years in the business for a contractor. We would be much further along if privatization had come along much earlier.
Another important step in space exploration and in cultivating a commercial market. Is the testing of the aerodynamics of the SpaceShipTwo primarily done in simulation? I would imagine there is some heavy duty CFD processing going on.
The implementation of a new diesel fuel standard in the US has considerably improved the environmental performance of diesel vehicles. The Environmental Protection Agency (EPA) says that the new ultra-low sulfur diesel (ULSD) fuel has combined with other improved technologies to reduce diesel's particulate matter (PM) emissions by 99%.
