Conscious Choice cover

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.

More suborbital private rockets in the news

Two news stories today about two different suborbital rockets built by private companies:

The first story outlines the results from the August 25 test flight of SARGE.

The rocket reached an altitude of approximately 28 km. Launch and recovery took place at Spaceport America on August 25th, 2018. The rocket carried nine payloads. The flight demonstrated the SARGE system’s reusability when the vehicle was recovered with damage only to sacrificial components. The test also demonstrated the capability of the autonomous control system and validated the preflight vehicle integration process.

They have designed SARGE to fly up to 200 times, and then plan to sell it to the military which will use it as a target in its own tests.

The second story describes a suborbital launch yesterday at Spaceport America. This suborbital rocket carried three NASA experiments, the most interesting of which was the first test of a heat shield designed to open like an umbrella.

Made out of thickly woven and highly heat-resistant carbon fibers, supported by semi-rigid ribs, the ADEPT system fits into existing vehicle launch systems, but expands when separated from the rocket into a configuration that allows it to perform its mission.

The ADEPT model tested Wednesday spread to 30 inches in diameter after separation. Venkatapathy said a diameter of 75 to 80 feet would be required to deliver a crew of seven or so human explorers safely onto the surface of Mars, which has a lower gravity pull than Earth.

He said a thicker carbon weave and different dimensions would be needed to deliver scientific equipment to the surface of Venus, a planet with a gravity pull nearly as great as Earth’s, making approaches hotter and faster.

Even if neither of these companies ever scale up to orbital rockets, they signal the change in how NASA does things. In the past NASA built its own suborbital rockets. Now, they are using privately-built rockets, which allows for competition and more innovation.

This is basically the same transition NASA is undergoing in its commercial manned program, going from being the sole builder and designer of spacecraft, enforced by a government-imposed monopoly, to merely a customer buying spacecraft from many private builders. It is a transition that can only generate good results in the future.

    Bob Z – “Even if neither of these companies ever scale up to orbital rockets, they signal the change in how NASA does things. In the past NASA built its own suborbital rockets”

    I suppose that it depends on your definition of “suborbital” but many of NASA’s sounding rockets, such as Aerobee (over 1000 launches) were designed and built by private contractors.

  • Col Beausabre: I agree that in the early days NASA hired contractors to build their suborbital sounding rockets, but over time the ownership and control and design of those rockets was taken over completely by NASA. What we are seeing today is a transfer of the owner, control, and design back to the private sector.

    There are definitely too many small launch vehicles being developed, right now, but the competition between them should give us a good small launch industry in the not too distant future.

    … 101 vehicles that are or have been under development in the last four years. “Let that sink in for a little bit,” [Carlos Niederstrasser of Northrop Grumman] said. “One hundred and one different entities are trying to build a small rocket to get all your small satellites into space. The number is staggering.”

    Of those 101 vehicles, he says that six are now operational, 34 are still in development, 11 have gone defunct, and he is unsure of the current status of another 11.

    The amazing growth in small launch vehicle development as well as the growth in satellite projects shows the difference that has happened in a decade, now that NASA, NOAA, and the U.S. military have shown an interest in using commercial services. A decade ago, investors were reluctant to get into space projects other than communication satellites, but now they are eager to invest in them.
