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.

Hubble lives on!

NASA has extended the contract with the Space Telescope Science Institute in Baltimore, Maryland to operate the Hubble Space Telescope for another five years, through 2021.

Launched in 1990 and repaired for the first time in 1993, Hubble appears likely to operate for more than three decades, a stunning record for any spacecraft.

    The Hubble is a marvelous and stunning piece of equipment. It would be great to see NASA contract out one or more private repair and refurbishment missions to Hubble in 2021 along the lines of COTS. It would spur private space to develop EVA and a host of other capabilities. I realize that a capsule such as Dragon isn’t nearly as capable as the shuttle with regards to grappling Hubble, but I believe the significant repairs were done to Skylab by an Apollo capsule before the station was occupied. Hubble would offer a similar challenge.

    Kudos to the many people who worked on Hubble over the years and its servicing missions.

    Maybe they should design 100 year spacecrafts?

    You have an excellent point. Up to now, we really have not had much ability to perform maintenance and repair on satellites or to refuel them with stationkeeping and attitude control propellants. Added to that the rapidity at which technology on satellites becomes obsolete and no one has really had much incentive to make long-lived satellites.

    As we have learned to maintain and update the Hubble Space Telescope, we have increased the incentive to make the basic telescopic optics last as long as Earth-based observatories, and as with Earth-based observatories, the instruments attached can be updated, replaced, or repaired as necessary. Now that we are figuring out how to refuel satellites, it should not be long before the 100-year spacecraft would be very desirable.

    if one of the 50 foot (fully extended, but folds up into a shorter length) Canadarms (Shuttle Remote Manipulator System arms from the space shuttle) does not fit in the Dragon’s trunk, which seems to be only 24 feet long, perhaps one could be made that does fit. That should help with any future Hubble servicing missions.

    This is what I mean, whenever I say that having 300 million Americans, or seven billion people worldwide, creating new ideas is better than having one committee thinking about them. People on this one site alone keep presenting good and interesting ideas for things to do in space or ways to improve our space exploration. It’s one of the reasons that I love reading everyone’s comments. This is the only website where I regularly read the comments. Sometimes they are even better than Robert’s original commentary. (Sorry, Robert, but you have some really smart, inspired, and thoughtful readers. Consider it as “too much success.”)

Readers: the rules for commenting!
