Designing a propulsion system for cubesats
The competition heats up: Just like the Chinese tests of a smallsat propulsion system noted in my previous post, this U.S. company is designing a propulsion system for cubesats.
McDevitt’s propulsion system is deceptively simple. It combines rocket-fuel-grade hydrogen peroxide with a patented proprietary catalyst to create a chemical reaction that results in thrust channeled through tiny square nozzles incorporated into the small satellite. The system allows the satellites to be steered or stopped. The only byproduct of McDevitt’s tiny rocket motors is water vapor.
Except for this quote the article doesn’t provide much information about the design, probably because the builders didn’t reveal the details for proprietary reasons. They hope to launch a test satellite by 2018.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
