Virgin Galactic releases Unity test flight program

In a change from the company’s past policy, which made many promises but never revealed their upcoming schedule in any detail, Virgin Galactic today released their planned test schedule for their new Unity spacecraft.

This test will be the first of a sequence of glide test flights. These flights will cumulatively allow us to test and prove the performance of the vehicle in a variety of conditions: both heavy (e.g. simulating the full weight of a load of fuel, oxidizer, and people) and light (with empty tanks) and in between, at a variety of flight path angles and airspeeds, and so forth. This testing of the “corners of the box” is designed to demonstrate how VSS Unity will perform as it returns from space, after the feather system is retracted and the vehicle becomes a glider and lands on the runway like an airplane. In addition, this phase of flight will also demonstrate and test our abort modes – which culminate in a safe glide back to the runway.

Our team of flight test experts has developed a set of requirements for each planned test flight as well as detailing exactly what we need to test in order to be ready to proceed to the next phase of rocket powered flights. We will fly as many flights as we need to in order to achieve all these objectives.

The schedule, quite properly, does not include any dates. In the past the company and Richard Branson, would make many grand promises about when their test program would be completed without providing any details of what they planned to do during that test program. This time, Branson is quiet, they have announced no schedule dates, but have provided good information about the test program itself. This is a very good change.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
