'Major Component Malfunction' Ends SLS Rocket Test Early. NASA Considers New Timeline (floridatoday.com) 112

"NASA's rocket charged with taking the agency back to the moon fired its four main engines Saturday afternoon, but the test in Mississippi was cut short after a malfunction caused an automatic abort," reports Florida Today...

"We did get an MCF on engine four," a control room member said less than a minute into the test fire, using an initialism that stands for "major component malfunction...." The engines fired for 12 more seconds after the exchange before an automatic shutdown was called. The test was meant to last eight minutes — the full duration needed for the booster during its Artemis program liftoff — but only ran less than two minutes.

Prime contractor Boeing previously said the test would need to run at least 250 seconds, or more than four minutes, for teams to gather enough data to move forward with transport to Kennedy Space Center and launch sometime before the end of the year. An exact plan moving forward, which could mean a second test and delay before transport to Florida, had not yet been released by Saturday evening.

Or, as the Guardian reports, "It was unclear whether Boeing and Nasa would have to repeat the test, a prospect that could push the debut launch into 2022."

In a press conference tonight, a NASA official specifically addressed the question of whether or not a launch this year was still feasible. "I think it's still too early to tell. I think as we figure out what went wrong, we're going to know what the future holds. And right now we just don't know...

"Not everything went according to script today, but we got a lot of great data, a lot of great information. I have absolutely total confidence in the team to figure out what the anomaly was, figure out how to fix it, and then get after it again... Depending on what we learn, we might not have to do it again."

They added that there was no sign of engine damage, and emphasized to reporters another way to view the significance of this afternoon's event. "A rocket capable of taking humans to the moon, was firing, all four engines at the same time." And they also stressed that this afternoon's result was not a failure -- but a test. "When you test, you learn things..."

"We're going to make adjustments, and we're going to fly to the moon. That's what the Artemis program is all about, that's what NASA is all about, and that's what America is all about. We didn't get everything we wanted, and yeah, we're going to have to make adjustments. But this was a test, and this is why we test.

"If you're expecting perfection on a first test, then you've never tested before."

"The date is set," NASA had tweeted Friday, thanking its partners Boeing Space and Aerojet Rocketdyne for Saturday's "hot fire" test of the SLS's core stage.

"One of NASA's main goals for 2021 is to launch Artemis I, an uncrewed moon mission meant to show the Orion spacecraft and Space Launch System rocket can safely send humans to our lunar neighbor," reported CNET. "But first, NASA plans to make some noise with a fiery SLS test on Saturday."

Below is the original report that schwit1 had shared from Space.com: It's a critical test for NASA and the final step in the agency's "Green Run" series of tests to ensure the SLS rocket is ready for its first launch... In the upcoming hot-fire engine test, engineers will load the Boeing-built SLS core booster with over 700,000 gallons of cryogenic (that's really cold) propellant into the rocket's fuel tanks and light all four of its RS-25 engines at once. The engines will fire for 485 seconds (a little over 8 minutes) and generate a whopping 1.6 million pounds of thrust throughout the test...

Following the success of this hot fire test and subsequent uncrewed missions to the moon, "the next key step in returning astronauts to the moon and eventually going on to Mars," Jeff Zotti, the RS-25 program director at Aerojet Rocketdyne said during the news conference. NASA's SLS program manager John Honeycutt agreed.

"This powerful rocket is going to put us in a position to be ready to support the agency in the country's deep space mission to the moon and beyond," he said.

        If this were SpaceX running this, they probably would have safed the system and dispatched engineers to debug and fix the control fault in realtime, with 50% odds that they'd be back up with a new attempt by the end of the day. SpaceX's operating principle is that if the timeline is long, it's wrong.

        But NASA doesn't work that way. :P

        Ignoring SLS itself and just comparing to Orion, this comparison [arstechnica.com] is just humiliating:

        ----

        Since that time, according to The Planetary Society's Casey Dreier, NASA has spent $23.7 billion developing the Orion spacecraft. This does not include primary costs for the vehicle's Service Module, which provides power and propulsion, as it is being provided by the European Space Agency.

        For this money, NASA has gotten a bare-bones version of Orion that flew during the Exploration Flight Test-1 mission in 2014. The agency has also gotten the construction of an Orion capsule—which also does not have a full life support system—that will be used during the uncrewed Artemis I mission due to be flown in 12 to 24 months. So over its lifetime, and for $23.7 billion, the Orion program has produced:

        * Development of Orion spacecraft
        * Exploration Flight Test-1 basic vehicle
        * The Orion capsule to be used for another test flight
        * Work on capsules for subsequent missions

        Obviously, that is not nothing. But it is far from a lot, even for a big government program. To see how efficiently this money could theoretically have been spent, let's use an extreme example.

        SpaceX is generally considered one of the most efficient space companies. Founded in 2002, the company has received funding from NASA, the Department of Defense, and private investors. Over its history, we can reliably estimate that SpaceX has expended a total of $16 billion to $20 billion on all of its spaceflight endeavors. Consider what that money has bought:

        * Development of Falcon 1, Falcon 9, and Falcon Heavy rockets
        * Development of Cargo Dragon, Crew Dragon, and Cargo Dragon 2 spacecraft
        * Development of Merlin, Kestrel, and Raptor rocket engines
        * Build-out of launch sites at Vandenberg (twice), Kwajalein Atoll, Cape Canaveral, and Kennedy Space Center
        * 105 successful launches to orbit
        * 20 missions to supply International Space Station, two crewed flights
        * Development of vertical take off, vertical landing, rapid reuse for first stages
        * Starship and Super Heavy rocket development program
        * Starlink Internet program (with 955 satellites on orbit, SpaceX is largest satellite operator in the world)

        To sum up, SpaceX delivered all of that for billions of dollars less than what NASA has spent on the Orion program since its inception.

        Not likely. The optimistic per launch cost to LEO with bulk pricing was about $6.5 million / tonne in 2019. An off-the-shelf working now Falcon Heavy launch is about 30% of that.

        What SLS can do is lift twice as much as a Falcon Heavy. So the real race is between SLS and Starship.

    I'm blown away that NASA is still using their old rocket building methodology. I get why - Congress runs NASA - but it's just so outdated.

    The rockets they are testing today are the flight rockets. If anything happens to them, NASA is set back years. Yes, NASA engineers are about the best in the world, and this has been meticulously planned for and measured and re-measured, but shit happens.

    Contrast with SpaceX, who has a warehouse full of engines. They build another one every week it seems. If one isn't working quite right, pull it, send it back to the shop, and slap another in. If you blow up a couple accidentally, send a truck to the warehouse to get a couple of more.

    I'm almost hoping that NASA blows these up. What's it going to take to force them to abandon their 50+ year old model?

      • Also worth noting, the RS-25 was an absolutely excellent engine in the 70s, and is still a very good one today. The Raptor is a big step forward, but the RS-25 is actually still more efficient. The Raptor has it licked in terms of total thrust, thrust to weight, reuse, and convenience of fuel, but again - the RD-25 is a really good engine.

          Have they actually demonstrated the capability to build new RS-25's? So far as I know, all testing to date has been using museum pieces. They could be flying crazy alien rockets from Area 51, but it still wouldn't mean anything without the tooling to build new ones if they're flying them on expendable boosters.

          • Last May contract awarded for building 18 more, we'll see if Aerojet Rocketdyne can.

            It's an engine that has accomplished things, vs. Raptor which is still in R&D and which to date hasn't gone 8 miles up. Could be a great engine but that's in the future.

            • While thatâ(TM)s true, SpaceX have done full duration burns with Raptor. In fact the hop to 12.5km involved a full duration burn, but not at full power obviously.

            • Well the engine no4 on this test accomplished an early shutdown a minute into "flight". That's a mission failed, you ain't going to the moon when that happens on real flight. If you pay 1.8 billion dollars for 18 more engines, you'd think such engines don't do that, you'd be wrong.

Same system could be used for extracting other materials such as various metals for manufacturing of the base. The procedures already exist.

            There's not much carbon on the moon, and it lacks the biological processes that concentrate it on Earth. The carbon isn't contributing to the efficiency of your propulsion either. If you're going to burn your drinking water, you might as well just use the hydrogen and oxygen directly.

            There is a lot of aluminum oxide laying around, which you can electrolyze into rocket fuel. Benefits include not using ultra-precious inner-system hydrogen at all.

    The old model used to work when there were unknowns. However we already had lots of experience in both theory and application, and there is no reason to back to the drawing board for new rockets.

    However what I see is, every NASA project becomes a repeat of the entire process, with almost no reuse of old data. All the contractors need to be fed after all. And this is really wasteful.

    We are still building the replacement for the Hubble for over 20 years now. It was supposed to launch in 2007 with a cost of 0.5 billion dollars. Now it has cost over 10 billion (20x increase) and nothing has launched yet (hopefully it is set to launch this year, again).

    We could have sent 10 incremental projects with the same money. And we would have tested the actual complex mirror mechanism in the way. Now if any of the delicate parts were to fail, we will have nothing to show for it.

    Obviously the non-incremental development cannot continue. Yes, waterfall is good for some things, but not practical for rocket science anymore.

    So on one hand I want to say "Space stuff is hard, failures are to be expected."

    But on the other hand, SLS has consume ~$20B, making it way overbudget, and is nearly 5 years overdue at this point. These are also Space Shuttle engines which, I don't know the full history on the SLS program, but I would imagine they decided to go with because they are a tried and tested design and were chosen because it'd get the program in space faster...even if they cost something like 150 to 180M per engine.

    Boeing also really needed a win on this. Between their 737-MAX screw up and the screw up on the Commercial crew capsule, which also uncovered more problems. This failure just feels like more egg on their face. To make matters worse, you have Lockheed doing the Orion capsule, another overbudget and overdue project, that has ran into problems where the whole capsule would have to be deconstructed to potentially fix it.

    It really makes me wonder if there is any point to these traditional defense contractors anymore besides being black holes to dump tax payer dollars into.

    Both companies are successful, they just have different goals.

    Musk's goals are cheaper spaceflight (and get his ass to Mars). He's doing that by designing efficient reusable rockets.

    Boeing's goal is to absorb as many taxpayer dollars as possible. They don't do this by putting anything in space. Delays and cost overruns are part of the method.
