NASA Completes Critical Design Review for Space Launch System
Nasa.gov ^ | 10/22/2015 | Kathryn Hambleton

For the first time in almost 40 years, a NASA human-rated rocket has completed all steps needed to clear a critical design review (CDR). The agency’s Space Launch System (SLS) is the first vehicle designed to meet the challenges of the journey to Mars and the first exploration class rocket since the Saturn V.

SLS will be the most powerful rocket ever built and, with the agency’s Orion spacecraft, will launch America into a new era of exploration to destinations beyond Earth’s orbit. The CDR provided a final look at the design and development of the integrated launch vehicle before full-scale fabrication begins.

“We’ve nailed down the design of SLS, we’ve successfully completed the first round of testing of the rocket’s engines and boosters, and all the major components for the first flight are now in production,” said Bill Hill, deputy associate administrator of NASA’s Exploration Systems Development Division. “There have been challenges, and there will be more ahead, but this review gives us confidence that we are on the right track for the first flight of SLS and using it to extend permanent human presence into deep space.”

The CDR examined the first of three configurations planned for the rocket, referred to as SLS Block 1. The Block I configuration will have a minimum 70-metric-ton (77-ton) lift capability and be powered by twin boosters and four RS-25 engines. The next planned upgrade of SLS, Block 1B, would use a more powerful exploration upper stage for more ambitious missions with a 105-metric-ton (115-ton) lift capacity. Block 2 will add a pair of advanced solid or liquid propellant boosters to provide a 130-metric-ton (143-ton) lift capacity. In each configuration, SLS will continue to use the same core stage and four RS-25 engines.

The SLS Program completed the review in July, in conjunction with a separate review by the Standing Review Board, which is composed of seasoned experts from NASA and industry who are independent of the program. Throughout the course of 11 weeks, 13 teams – made up of senior engineers and aerospace experts across the agency and industry – reviewed more than 1,000 SLS documents and more than 150 GB of data as part of the comprehensive assessment process at NASA’s Marshall Space Flight Center in Huntsville, Alabama, where SLS is managed for the agency.

The Standing Review Board reviewed and assessed the program’s readiness and confirmed the technical effort is on track to complete system development and meet performance requirements on budget and on schedule.

The program briefed the results of the review in October to the Agency Program Management Council, led by NASA Associate Administrator Robert Lightfoot, as the final step in the CDR process.

This review is the last of four reviews that examine concepts and designs. The next step for the program is design certification, which will take place in 2017 after manufacturing, integration and testing is complete. The design certification will compare the actual final product to the rocket’s design. The final review, the flight readiness review, will take place just prior to the 2018 flight readiness date.

“This is a major step in the design and readiness of SLS,” said John Honeycutt, SLS program manager. “Our team has worked extremely hard, and we are moving forward with building this rocket. We are qualifying hardware, building structural test articles, and making real progress.”

Critical design reviews for the individual SLS elements of the core stage, boosters and engines were completed successfully as part of this milestone. Also as part of the CDR, the program concluded the core stage of the rocket and Launch Vehicle Stage Adapter will remain orange, the natural color of the insulation that will cover those elements, instead of painted white. The core stage, towering more than 200 feet tall and with a diameter of 27.6 feet, will carry cryogenic liquid hydrogen and liquid oxygen fuel for the rocket’s four RS-25 engines.

The integrated spacecraft and payloads are nearing completion on their CDR. Flight hardware currently is in production for every element. NASA is preparing for a second qualification test for the SLS boosters, and structural test articles for the core and upper stages of the rocket are either completed or currently in production. NASA also recently completed the first developmental test series on the RS-25

I do not see how this helps Muslims.

This is completely outside of NASA’s charter.

On the contrary. With the muzzle in chief about to vacate the Oval Office, NASA will now return to it’s original intent, planetary exploration and launching crews into the the Great Out There.

Beat me to it...

My first thought, though, was - we’re stepping BACK to plain old rockets?

I very seriously doubt it ever will. They will spend billions developing it, then if congress or a future president doesn’t cancel it the NASA bureaucrats will decide they have insufficient funding to complete it and cancel it themselves.

NASA is only interested in spending money, putting people in space is too risky for them.

You seem to not understand what has happened, and what will happen.

This is way bigger than Obama.

In fact, the powers and principalities are the struggle between God and the Enemy.

I hear what you’re saying.

Had a meeting several months ago which included a NASA PhD (more a DC NASA bureaucrat, than engineer). While listening to the details of his project, I thought it was interesting, would further aviation, and would be something that could be done in a few years with the help of industry. His closing comments included,”..but I don’t expect this to be done in the next 10 or even twenty years, (laughs).” What the !? Apply yourself and accomplish something instead of looking for cash cows!

I want to be gung-ho about SLS. Let’s get America back launching into space. We should be the leader there. As it is, I fear we’ll share the same fate as Portugal did in the age of sail: fantastic out of the gate, but bested by other powers in the long run.

Without Werner Von Braun at the helm of the program, I have to admit I’m not optimistic about success. Hope I’m wrong. Maybe Mohammad is every bit as capable as Von Braun.

WOW! All this hub-bub about “back to the future” this week and NASA tops it off with “back to the past”. So, let’s see. It’s been since July 2011 when the last shuttle flew and this new improved Apollo capsule will fly in another what, 8 years. Maybe. Obviously this ain’t our grandpa’s NASA.

Yeah, it seems like an impossible task to launch with the way politics are. Every 4-8 years, different parties in charge, or a president at odds with Congress. No chance. Maybe private industry has a better chance but only if there is a financial incentive to do it. ....or you can wait till I retire and start tinkering. I’ll do it.

SLS is a ridiculous, expensive and useless waste. Sure, it’s a Big Rocket and all, but it is nothing more than a kludge of differing bureaucratic and crony imperatives.

The two massive solid boosters are simply terrible ideas, and are put there to placate a certain Senator in whose state exists the manufacturer. In actual engineering reality, solid boosters are very erratic items that shake the bejeesus out of anything they’re strapped to. Cross-feeding liquid propellant would be optimum, but the Senate has its priorities.

NASA has pissed away between $10 and $15 billion on this lousy design over the last several years. Maybe more. And it still won’t fly for years more, if ever.

NASA is a command bureaucracy, nothing more. They were once capable of so much, but are now nothing more than a hole to pour buckets of money into, like all other bureaucracies...

And this ‘technological marvel’ of the 21st century, rehashed from mid-20th century designs.....

They figured how to touch-down on Earth (LAND) yet? Maybe a few metric conversion ‘mistakes’ again?

Dismantle the monstrosity and leave it up to the private sector. Another illegal boondoggle over its expiration date.
