DARPA has launched a program to use airplanes as a launchpad for putting satellites in orbit.
The Pentagon’s research agency, the Defense Advanced Research Projects Agency (DARPA), also anticipates slashing small satellite payload costs from more than $30,000 per pound to less than $10,000 per pound — making such launches three times cheaper. . . . DARPA wants the program to demonstrate at least 12 launches of 100-pound payloads to low Earth orbit, with each launch costing about $1 million. Launches could start as soon as 2015, according to DARPA’s official announcement of the program on Nov. 4.
At first glance this appears to be good news for Orbital Sciences and its Pegasus rocket, the only commercial launch system that has successfully put satellites into orbit using a commercial L1011 airplane as its first stage. At the same time, however, it appears DARPA is pushing for new technology to lower costs below what Orbital charges, meaning the game is open to anyone.

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.
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.
