Capitalism in space: Stratolaunch is now considering building and launching hypersonic rocket test program using its giant Roc airplane.
In the concept study presented this week, Corda and his colleagues provide a detailed description of a delta-wing testbed plane called the Hyper-Z. It would be 83.4 feet long, with a wingspan of 32.4 feet and a launch weight of about 65,000 pounds.
Stratolaunch’s hydrogen-fueled PGA rocket engine would serve as the plane’s main propulsion system, but it could also be equipped with an air-breathing propulsion system, such as a scramjet engine. The flight profiles could accommodate a maximum speed of Mach 11, or a maximum altitude of 477,000 feet.
Hyper-Z would be launched from Stratolaunch’s mammoth twin-fuselage carrier airplane [Roc], which has a record-setting wingspan of 385 feet.
I must emphasize that this is only a concept proposal at this point. The company still has to verify the operation of Roc.
What this proposal does suggest to me is that the company is still struggling to find a profitable use for Roc, and customers to go along with it. This concept appears to be a lobbying effort to both the military and NASA, offering them Roc as a testbed for such flight tests.
From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.
Unfortunately, that is exactly where that journey takes him.
The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.
He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.
