NASA Approves Production of Most Powerful Rocket Ever

As reported by the Sydney Morning Herald, NASA has given a green light to the production of a new motor, dubbed the Space Launch System, intended to enable deep space exploration. Boeing, prime contractor on the rocket, announced on Wednesday that it had completed a critical design review and finalized a $US2.8-billion contract with NASA. The last time the space agency made such an assessment of a deep-space rocket was the mighty Saturn V, which took astronauts to the moon. ... Space Launch System's design called for the integration of existing hardware, spurring criticism that it's a "Frankenstein rocket," with much of it assembled from already developed technology. For instance, its two rocket boosters are advanced versions of the Space Shuttle boosters, and a cryogenic propulsion stage is based on the motor of a rocket often used by the Air Force. The Space Frontier Foundation, an advocacy group and frequent NASA critic, said Space Launch System was "built from rotting remnants of left over congressional pork. And its budgetary footprints will stamp out all the missions it is supposed to carry, kill our astronaut program and destroy science and technology projects throughout NASA."

. Space Launch System's design called for the integration of existing hardware, spurring criticism that it's a "Frankenstein rocket," with much of it assembled from already developed technology.

I would much rather them use existing tried tech and incrementally advance them rather than try a radical new design. A new design would take extra years of testing before it is ready for use but if we can tweak existing tech, and make it useful for deep space why not??

Based on the next sentence it tells me that they are more concerned with bringing home the bacon than making progress in space.

This summary is a load of bull. As is the article. Production of a new motor my ass. The SLS is supposed to use 4 RS-25 Space Shuttle Main Engines in the center core, of which there are 15 and parts of another in stock, and two 5 segment Solid Rocket Boosters similar to those of the Space Shuttle. The second stage is based on a Delta IV EELV second stage using the RL-10. What is 'new' here in terms of propulsion? They are adding another segment to the SRBs. Whoopie do.

Get this: SLS is predicted to cost as much as the Space Shuttle did per year, but it will launch once every 2-3 years instead of 4 times a year like the Space Shuttle. If you do the math they have RS-25 engines for 3-4 flights. SLS is expendable remember? The production assembly line for RS-25 has been closed years ago. So if they want to fly more than 3-4 flights with it they will probably have to design a new engine which will take like 5 years to do. At best. The whole thing is sheer nonsense.

I don't understand the criticism regarding ...

Basically, they are repeated all the old mistakes of Shuttle and ISS. Single unaffordable top-down designs, expensive sole-source cost-plus contracts, convoluted designs more intended to feed the contractor networks in Congressional districts than to deliver improved hardware, flubbery half-hearted missions that mutate to fit the rapidly contracting hardware abilities rather than hardware designed for missions. And because everything is so expensive and poorly planned, development has to be smeared out over decades, giving time for endless Congressional budget games with the attendant schedule and cost blow-outs, and design compromises piled on top of design compromises just to get something launched.

Paraphrasing Gen. Augustine, in the analysis over Constellation (SLS's precursor), "If someone handed it to NASA, already build and paid for, NASA still couldn't afford to operate it."
