Aerojet Rocketdyne sets record testing new rocket engine
The competition heats up: In recent static fire tests of its new AR-1 rocket engine Aerojet Rocketdyne set a record for the highest chamber pressure for any American engine using oxygen and kerosene.
They hope to convince ULA to use this engine in its Atlas 5 rocket to replace the Russian engine they presently use. At the moment, though ULA has made no commitment, it appears however that the company is favoring Blue Origin’s engine instead. That Congress favors Aerojet Rocketdyne is their one ace in the hole, since Congress controls the purse strings.
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
