Sierra Nevada abandons its own hybrid engine for Dream Chaser
The 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.
Readers!
Every February I run a fund-raising drive during my birthday month. This year I celebrate my 72nd birthday, and hope and plan to continue writing and posting on Behind the Black for as long as I am able.
I hope my readers will support this effort. As I did in my November fund-raising drive, I am offering autographed copies of my books for large donations. Donate $250 and you can have a choice of the hardback of either Genesis: the Story of Apollo 8 or Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space. Donate $200 and you can get an autographed paperback copy of either.
Please consider supporting my work here at Behind the Black. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Every one of those 2020 conclusions has turned out right.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

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.
