DARPA picks Boeing to build a test design of an air-launched satellite launcher.
The competition heats up: DARPA has chosen Boeing to build a test design of an air-launched satellite launcher.
This engineering research is in parallel with the airborne launcher research of Scaled Composites (on SpaceShipTwo) and Stratolauncher. When you add SpaceX’s effort to make its first stage reusable, you get a real sense where the future of rocket design is heading: rockets in which the first stage is entirely reusable, returning safely to Earth either by a horizontal or vertical landing.
Now available in hardback and paperback as well as ebook!
From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.
“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.
All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. The ebook can also be purchased direct from my ebook publisher, ebookit, in which case you don't support the big tech companies and I get a bigger cut much sooner.
Autographed printed copies are also available at discount directly from me (hardback $24.95; paperback $14.95; Shipping cost for either: $5.00). Just email me at zimmerman @ nasw dot org.

How long is the satellite expected to be in use after orbital insertion?
The US military already has a tested a system using normal ballistic launch vehicles for replacing GPS and communications satellites over a battle field in case an enemy takes out the ones we already have in place.
Granted they only last a few months at most.
We have had air launched anti satellite systems tested and working for years. All we need do is replace the warheads with satellites.
It sounds like they gave a contract to a company with years of experience building anti satellite systems already.
No one else had a chance.

It only carried a 14 Kg payload but was tested successfully several times.
With modern electronics reducing the carried weight. and the fact it no longer needs targeting systems I bet it could be modified to fit a 40kg payload easy.
