Sierra Nevada abandons its own hybrid engine for Dream ChaserThe competition heats up: Sierra Nevada has decided not to use its own hybrid engine on its Dream Chaser manned shuttle.
With the apparent decision by Virgin Galactic to also abandon this engine, it would appear that hybrid rocket technology is not yet ready for prime time, if ever.
Posted from Spokane, Washington, where Diane and I will be visiting my oldest friend Lloyd and his family for the rest of the week.
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 or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. 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

Hope you get out and enjoy some of our spectacular outdoor activities. You might enjoy seeing the channeled scab lands from the Columbia Plateau Trail or from a boat on one of the local lakes. Klink,’s, at Badger Lake, has great food.
If you do hit any local trails or parks, be sure to check if a Discover Pass is needed for parking. Thankfully, one is not needed on the Centennial Trail.
And yet one more company finally abandons the old bottle rocket idea.
We did not come prepared for hiking, as this is a visit with old friends who don’t do that stuff. Instead, we go to restaurants and watch movies.
After all, it *is* rocket science, and it isn’t easy to get into space.
Regardless, I hope you enjoy your time here. Spokane means children of the sun and we live like it :)
How many other launch groups are using hybrid engines?
From what I can guess not many if any.
Which should be a clue as to how effective it is.
