Aerojet Rocketdyne wins contract from Lockheed Martin to build more Orion engines
Aerojet Rocketdyne announced yesterday that it has been awarded a new $67 million contract from Lockheed Martin to build the Orion propulsion engines for Artemis missions six though eight.
This contract option includes delivery of three additional sets of Orion’s service module auxiliary engines and three additional jettison motors. The eight auxiliary engines each produce 105 pounds of thrust to help maintain Orion’s in-space trajectory and position, and supplement the Orion Main Engine. The jettison motor, located on Orion’s Launch Abort System (LAS), generates 40,000 pounds of thrust to separate the LAS from the crew module during both nominal operations and abort scenarios, allowing the spacecraft to continue on its journey. The jettison motor is the only motor on the LAS that fires during every mission.
These Artemis missions are not expected to occur until very late in this decade, by which time Starship will likely be making regular commercial trips to the Moon. At that time Orion will look increasingly ridiculous next to Starship, and will demonstrate starkly the difference in what government can do versus a free private sector.
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

The only way I can imagine anything positive about Orion is if it is in fact a phony program, designed to reimburse Lockheed for a top-secret hypersonic SR-72 type airframe. That, they could probably pull off!

With or without Starship, I’d be beyond shocked if Artemis 6-8 fly before the mid 2030’s, honestly.

For this kind of money, I hope to gosh it’s powered by anti-gravity.
Orion will be flying after Starship is scrapped.
“Orion will be flying after Starship is scrapped.”
If it is, it will amount to a dismal failure for us as a space power.
For $4 billion a pop, we could do 4 Discovery missions and a pair of New Frontiers probes every year. I mean, if *science* is the only pretence we are after (though we all know it’s not); because we’d get far more science out of all that than whatever brief government rock collecting field trips an Orion can lug to Luna every 12-18 months.
Healthy skepticism about what SpaceX can do is one thing; but I swear, some people seem actively invested in its failure.
“…we’d get far more science out of all that than whatever brief government rock collecting field trips an Orion can lug to Luna every 12-18 months.”
And Orion can’t lug anything to the lunar surface, just to lunar orbit. For a few weeks. Using a giant, single-use rocket.
