Redwire to launch first commercial and private greenhouse in space

Capitalism in space: The in-space 3D printing company Redwire announced yesterday that it will launch to ISS the first privately-built greenhouse, scheduled for a ’23 liftoff.

Redwire is developing this greenhouse for agricultural company Dewey Scientific.

During the inaugural flight, Dewey Scientific will grow industrial hemp in the Greenhouse for a gene expression study. The company collaborated with Redwire, contributing technical details about the 60-day experiment and describing its potential to demonstrate the capabilities of the facility, while advancing biomedical and biofuels research.

The long term goal is to prove that this technology can produce products of value on future space stations, products that can then be sold on Earth. That both companies appear willing to invest some of their own research and development capital in this project suggests they both believe there will be a strong viable market for these products.

Conscious Choice cover

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.

    I know hemp is a remarkable, and very useful plant, pretty much the entire plant is good for some use, and no doubt the scientific reasons behind its use are valid… But I can’t help but getting a giggle from the idea of “spaced out Spacemen”
    ( Although I’m not sure there is a smoking area on the ISS)

    Aah, but can they make brownies??

    Just to prove a point I guess.

    All plants are 100% usable and recyclable. Hemp though is not the most easily biodegradable. And who needs textiles in space?
    Any plant part grown in space and not eaten should be turned back into dirt otherwise you have to store it and throw it away. Then you have to send water and nutrient mass back up equal to or better than the mass you send down as waste.

    Until we have a station with at least a partial gravity growing anything in space is just an experiment in techniques that will more than likely not be used for permanent habitation.

    I would have guessed that large-scale crystal growth would be among the earliest microgravity industrial applications, before fiber growth. But perhaps the problem of returning the “produce” without destroying it is more tractable with fibers than with crystals?
