NASA Worker Caught in Acts of Sabotage on ISS Bound Computer

Not sure your point ... the Saturn 5 was a cluster, and the shuttle uses the boosters and 3 main engines.

The Russian boosters and early ICBMs were clusters of clusters. Like I said, they couldn't build a big motor, so they used a an existing design, just building a bunch. The Saturen used a few BIG engines. Five F-1s in the first stage, five J-2s in the second (and one J-2 in the third). The Vostok vehicle used a bunch of small ones. Five clusters of 4 engines each in the first stage, with the center four also function as the 1/2 stage similar to the US Atlas, which dropped the outside two engines IIRC the Vostok lanch vehicle (derived from the R-7/SS-6 ICBM) dropped the outside 4 clusters of 4 engines each.

The R-7/SS-6 was originally to have a single engine per cluster, but then the required payload weight was raised from 3,000 kg to 5,500 kg, because that's the size of the thermonuclear weapon they could build.

” Like I said, they couldn’t build a big motor, so they used a an existing design, just building a bunch.”

So ?

Saying they “couldn’t” makes no sense - if they had something that did the job cheaper, why bother ?

Did we wait until we could launch the shuttle on one big engine without boosters ? ... No ... it would be stupid to do so

NOW, they have no money, but they can launch those old rockets to re-supply when we can’t ...

This we understand well. The engineering bi-products of our aeronautical ventures in the USA, including those from our space research and development, make their way down the chain into civilian use probably as fast as they can.

In Russia, R&D is kept in the state vaults, probably even now.

When we lived near Vladivostok in 1996 and 1997, very few single-family dwellings in the nearby town of Ussuriysk (1996 pop. 225,000)had indoor toilets. Being first in space didn’t help the common Russian much.

[John Leland 1789]

Can’t lie about it. Yep, I’d like to know.

“Being first in space didn’t help the common Russian much.”

True, and the hundreds of billions of dollars NASA spent over the years hasn’t helped the common American very much. There was a thread on FR about a year ago in which virtually every claim about NASA’s great contributions to everyday life in the U.S. (even Tang!) was debunked.

I need to gouge my eyes out, now.

If it was the part made in Russia how would you tell if it was sabotaged? It probably does not work anyway.>>
Nice to hear it from Americans. You people lost 2 orbiters out of 4 with 14 crewmembers burned, NASA has the highest death toll for space flights, your space heroes ride to space under alcholol, also remember an air leak in american segment of ISS, ballistic (very dangerous) landing of Soyuz because american astronaut pulled the wrong handle while entering the landing capsule, failure of American spacesuits on ISS and so on... Yeah, right, Russian staff doesn’t work.

Oh, and why is that that american heavy rockets fly on russian engines?

[stm]

Looks like I hit a nerve. You know why we have more mishaps than the ruskies? BECAUSE WE STILL ROUTINELY FLY.

And where on earth did you get that idea that we uses russian engines in our rockets? Every heard of Teledyne or GE? Apparently not.

BECAUSE WE STILL ROUTINELY FLY.>>>
Oh, really? How many Shuttle launches within... let’s say lat 4 years? Two or three?

And where on earth did you get that idea that we uses russian engines in our rockets? Every heard of Teledyne or GE? Apparently not.>>> Ever heard of Wikpedia?

RD-180 Engine
RD-180 Engine

The RD-180 is a dual-combustion chamber, dual nozzle, Russian-developed rocket engine, derived from the RD-170 used in Zenit rockets. Like the four chamber RD-170, the combustion chambers of the RD-180 share a single turbopump unit. Rights to employ the RD-180 were acquired by General Dynamics Space Systems Division (later purchased by Lockheed Martin) in the early 1990s for use in the Evolved Expendable Launch Vehicle (EELV) and the Atlas program. As these programs were conceived to support United States government launches as well as commercial launches, it was arranged for the RD-180 to be co-produced by Pratt & Whitney. All production to date has been in Russia. The engine is currently sold by a joint venture between Pratt & Whitney and NPO Energomash (the Russian developer and builder) called RD AMROSS.
