SpaceX has test fired its Grasshopper replacement test vehicle.
The competition heats up: SpaceX has test fired its Grasshopper replacement test vehicle.
Unlike Grasshopper, which only had one engine, the Falcon 9R (pronounced “niner”) is the equivalent of a Falcon 9 nine engine first stage. They fired it on the launchpad for 5 seconds in preparation for future vehicle take off and landing tests.

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

I’m only about 150 miles from there (eastern AZ.) I should make a trip!
Actually, the Grasshopper 2/F9R being tested only has three engines installed at the moment, the others are to come later. More than the original Grasshopper which means sufficient thrust to carry a heavier load to higher altitudes for testing, but not yet a complete first stage.
I am assuming you are right. The reason I assumed it was a full first stage is because the article talks about developing a full thrust of 1 million to 1.5 pounds (depending on altitude), which I thought was what the first stage did. Am I in error again?
You are correct that it WILL eventually have all 9 engines, the config being tested at McGregor apparently only has three engines. At some point they will install the other 6 for testing in New Mexico. Exact details are of course scarce.
Otherwise it is supposed to be a full up first stage.
Have you seen a cost quote per engine? It would be interesting to know what Spacex is considering the cost to build a Merlin 1D. One of the changes quoted for the 1D build is simpler, and cheaper to build. Wonder how much difference between 1C and 1D there is.
