NASA fixes SLS issue, prepares for full hot fire engine test of core stage

11:32 am

My heart be still! NASA engineers have successfully fixed a valve on the inside of the core stage of the agency’s SLS rocket, making it possible for the continuation of the ongoing test program leading up to its first and only full static fire test on December 21st of the rocket’s core stage, prior to the rocket’s first launch.

Over the weekend, engineers at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, successfully repaired a valve inside the core stage of the agency’s Space Launch System (SLS) rocket. The team designed an innovative tool to remove and replace the valve’s faulty clutch while the core stage remained in the B-2 test stand, and without removing the entire valve. Subsequent testing of the repaired valve confirmed that the system is operating as intended.

If that static fire test fails for any reason, it will likely delay the first Artemis launch by at least a year, if not longer. Right now there is a slim chance that SpaceX’s Starship will complete its first orbital launch before SLS (which NASA has been developing for only seventeen years). Further delays would almost guarantee it.

Such an event will make the entire SLS program appear kind of stupid, irrelevant, and an utter waste of money. But then, SLS is exactly that, a wasteful boondoggle designed not to get American astronauts into space but to spend money in Congressional districts and states. These corrupt legislators actually like the delay and failure, because it extends the contracts and funnels more money to their constituents over a longer period of time. Who cares if anything ever really gets accomplished, or the interests of the U.S. are advanced? What really matters is making sure Congressmen get photo ops, and their big space backers get contracts so they can continue to make campaign contributions.

Senate fails to fully fund manned lander for Trump’s 2024 lunar mission

10:30 am

The Senate appropriations committee’s budget recommendations for NASA, released yesterday, has refused to fully fund the development of the manned lander needed for Trump’s 2024 lunar mission.

The Senate Appropriations Committee released its recommendations for all 12 FY2021 appropriations bills today. The Commerce-Justice-Science (CJS) bill provides NASA with $23.5 billion, $1.75 billion less than requested. The House-passed bill keeps the agency at its current level of $22.6 billion, so the final compromise likely will be somewhere in that range. NASA’s request for Human Landing Systems (HLS) for the Artemis program was particularly hard hit on both sides of Capitol Hill.

NASA had requested $3.4 billion for building the lunar lander in time for 2024. The House appropriated $628 million. Today’s Senate recommendation budgeted $1 billion. This practically guarantees that no manned lunar mission will happen by 2024.

None of this is a surprise. The politicians in Congress from both parties don’t really want to rush this program. For them it is better to stretch it out for as long as possible, spending mucho bucks in their states and districts. Nothing will be accomplished, but they will be able to tell their constituents they brought the jobs home.

Useless and empty jobs, but jobs nonetheless.

Europa Clipper to be delayed because of SLS bottleneck

10:06 am

Because Boeing will be unable to provide an SLS rocket in time for the planned 2024 launch of Europa Clipper, once the probe is completed NASA will be forced to put it in storage.

The problem is that Congress has mandated that the Jupiter probe be launched on SLS, but has only funded the first two Artemis launches to the Moon. Boeing will also need at least three years to build it, meaning that even if the money from Congress appeared today, it would likely not be ready for its ’24 launch date.

In terms of rocket science, right now, Europa Clipper can launch on a commercial vehicle, like SpaceX’s Falcon Heavy or United Launch Alliance’s Delta-IV Heavy rocket, although the mission would then need a longer cruise time to reach its destination.

But in terms of the law, NASA’s hands are tied.

“Because of that, we’re planning to build the Europa Clipper and then put it into storage, because we’re not going to have an SLS rocket available until 2025,” Bridenstine said. “That’s the current plan. I don’t think that’s the right plan, but we’re going to follow the law.”

Though the common sense thing for Congress to do would be to release NASA from this mandate and allow the agency to pick the launch rocket, do not expect that to happen. Congress wants SLS because of all the pork it produces. They will not allow NASA to reduce its reliance on SLS one iota, if they can. Unless pressured publicly (which I think is NASA’s goal with this announcement), Congress will let Europa Clipper sit in a warehouse for years, at a cost of between $36 to $60 million per year, waiting for SLS.

First full static fire test of SLS’s core stage scheduled for November 14

10:02 am

NASA has now scheduled the first full static fire test of the core stage of its SLS rockt for no earlier than November 14th.

Currently installed in the B-2 Test Stand at NASA’s Stennis Space Center in Mississippi, the massive 212-foot-tall core stage has completed six of eight planned green run tests before it can be shipped to KSC by barge as the final piece of the first mission of the Artemis program, slated for launch in November 2021.

Officials with NASA as well as contractors Boeing and Aerojet Rocketdyne gave an update on the core stage progress on Tuesday, stating the tentative date for the hot fire test is Nov. 14, and the target for it to be loaded onto the Pegasus barge for the trip to Florida is Jan. 14.

“So far the design has held together extremely well. We’ve not really had any surprises,” said John Shannon, Boeing’s vice president and program manager for the Space Launch System.

Unlike SpaceX, which uses tests like this to figure out how to build its rockets, NASA uses these tests to confirm its designs and construction at the very end of development. This difference in approach, now so clearly illustrated by simultaneous tests going on from both, I think shows the advantages of SpaceX’s approach. By testing during development, SpaceX can quickly fix any problems it finds, and move forward fast with better designs. This approach also results in a less expensive final result.

NASA instead must make sure its designs are perfect on the drafting board, which therefore requires their engineers to include gigantic design margins, resulting in long construction schedules and an expensive final product. Worst of all, should SLS fail during this final test, NASA will face some very difficult and expensive choices, none good.

NASA lays out Artemis budget and plan to get astronauts to Moon

10:10 am

In a obvious lobbying effort to get Congress to fund the Trump administration’s Artemis project to land humans on the Moon by 2024, NASA yesterday released a new updated plan and budget for the program.

More here.

The document [pdf] outlines the specific plans for each of the first three Artemis flights, with the first unmanned, the second manned and designed to fly around the Moon, and the third to land a man and a woman on the Moon. Overall the plan is budgeted at about $28 billion, with $3.2 billion needed immediately to fund construction of the lunar lander. From the second link:

Bridenstine said he remains optimistic Congress will fully fund lander development because of what he described as broad bipartisan support for the Artemis program. He said he’s hopeful an expected continuing resolution that would freeze NASA’s budget at last year’s spending levels will be resolved in an “omnibus” spending bill before Christmas or, if the CR is extended, by early spring. “It is critically important that we get that $3.2 billion,” he said. “And I think that if we can have that done before Christmas, we’re still on track for a 2024 moon landing. … If we go beyond March, and we still don’t have the human landing system funded, it becomes increasingly more difficult.”

And what happens then?

“It’s really simple. If Congress doesn’t fund the moon landing program, then it won’t be achieved (in 2024), I mean it’s really that simple,” Bridenstine said. But he quickly added: “I want to be clear, if they push the funding off, our goal will be to get to the moon at the earliest possible opportunity.”

I remain doubtful the present Congress, with the House controlled by the Democrats, will fund this 2024 lunar landing. Since 2016 the entire political platform of the Democratic Party has been “oppose anything Trump.” They will not fund this project if it means he will get this landing during his second term.

If however Trump loses in November, the lame duck Congress might then go ahead and fund it before December, since the landing in 2024 will then occur during the Biden presidency.

Technically the plan reveals that NASA is trying to accelerate the development of the rendezvous and docking software for Orion. During the second flight, the first manned, the crew will do proximity maneuvers with the upper stage of the rocket. Under previous management NASA had not included this ability, as they had not planned to have Orion do any rendezvouses or dockings. That lack makes it impossible for Orion to fly on any other rocket but SLS. This change means the Trump administration recognizes this is a problem, and wants to fix it, especially because they also recognize that SLS is a poor long term option for future lunar missions.

First manned Artemis Moon mission might not go to south pole

3:59 pm

In order to meet the Trump administration’s 2024 deadline for the first Artemis manned lunar landing, NASA is now considering sending that first mission to an equatorial target, rather than the Moon’s south pole.

The Artemis program landing site issue came up at two separate events with agency leaders this week, beginning with NASA Administrator Jim Bridenstine’s comments to open a digital meeting held by a NASA advisory group called the Lunar Exploration Analysis Group, on Monday (Sept. 14).

“For the first mission, Artemis 3, our objective is to get to the south pole,” Bridenstine said. “But … it would not surprise me if, for example, if we made a determination that the south pole might be out of reach for Artemis 3, which I’m not saying it is or isn’t,” interest in the Apollo sites may win out.

The engineering to get to the polar regions is more challenging, so rather than delay that first mission they are considering simplifying it instead.

The fact remains that Congress has still not funded any Artemis missions beyond the first unmanned and first manned flights, neither of which will land on the Moon. Whether that money will ever be forthcoming really depends entirely on the November election, as well as the success or failure of the upcoming full-up static fire engine test of the SLS first stage.

Northrop Grumman successfully tests SLS solid rocket booster

9:03 am

Northrop Grumman yesterday successfully test fired a solid rocket booster to confirm its design for use on NASA’s long-delayed and overbudget SLS rocket.

The test, completed at the T97 test area at Northrop Grumman‘s facility in Promontory, Utah, took place on Wednesday, September 2, 2020, at 1:05 PM Mountain Daylight Time (19:05 UTC). A single five-segment SLS solid rocket motor with a thrust of up to 3.6 million pounds was ignited, and burned for approximately two minutes.

The booster is an expanded version of the solid rocket boosters used on the space shuttle, with five segments instead of four, and in fact will use previously flown segments from past shuttle launches. Since this booster will not be recovered, these launches will be the last time those segments fly.

Another SLS screw-up related to Europa Clipper

3:16 pm

Despite being required for years by a legal congressional mandate to use SLS to launch Europa Clipper to the moon of Jupiter, NASA engineers have suddenly discovered unspecified “compatibility issues” that might make use of the rocket problematic.

At an Aug. 17 meeting of NASA’s Planetary Science Advisory Committee, Lori Glaze, director of NASA’s planetary science division, said the Europa Clipper mission had recently discovered compatibility issues involving the Space Launch System, the vehicle preferred by Congress to launch the spacecraft. “There have been some issues that have been uncovered just recently,” she said of the use of SLS for Europa Clipper. “We are in a lot of conversations right now with human exploration and others within the agency about what kind of steps we can take going forward.”

She did not elaborate on the compatibility issues regarding SLS. Such issues, industry sources say, likely involve the environment the spacecraft would experience during launch, such as vibrations. That environment would be very different for Europa Clipper, a relatively small spacecraft encapsulated within a payload fairing, than for the Orion spacecraft that will be the payload for most SLS launches.

“We are currently working to identify and resolve potential hardware compatibility issues and will have more information once a full analysis has been conducted,” NASA spokesperson Alana Johnson said in an Aug. 18 statement to SpaceNews. “Preliminary analysis suggests that launching Clipper may require special hardware adjustments, depending on the launch vehicle.”

This is a joke. It is also absurd and disgusting. Finally, it is also par for the course for NASA and all of today’s government, at all levels. They can’t do anything competently. From the beginning Europa Clipper was mandated to fly on SLS. And yet, they didn’t design the two to be compatible?

Based on this example we should of course demand that the government and these bureaucrats be given more power and more control over our lives. Of course.

House rejects Artemis; Senate funds Artemis

11:51 am

The Senate gives, the House taketh away: Even as the Democratically-controlled House continues to refuse the Trump administration’s request for $2.6 billion to fund its 2024 manned lunar landing, the Republican-controlled Senate has provided $1.6 billion of those funds in the next COVID-19 stimulus package.

This illustrates why such stimulus packages are utterly corrupt. Much of the money allocated has little to do with helping the country recover from the Wuhan panic, but is instead earmarked for the favorite agencies of the politicians. The Republicans are also trying to use this package to sneak across funding for Artemis without the House Democrats noticing, or being able to object.

It remains to be seen whether that strategy will work. Either way, we continue on the road to bankruptcy and financial collapse, as the federal government is trillions in debt, and simply doesn’t have the money for any of this.

Midnight repost: The Lie that is Orion

11:59 pm

The tenth anniversary retrospective of Behind the Black continues: This essay, written in July 2016, might provide modern readers with some background and context into the uselessness of NASA’s over priced, over designed, and behind schedule Orion capsule. The only thing that has changed in the four years since is that NASA has stopped claiming Orion is an interplanetary spaceship. They now freely admit that to get to Mars they need to build and assemble much larger ships, of which Orion will only be a tiny part.

————————-
The Lie that is Orion

Several weeks ago NASA put out one of its periodic press releases touting the wonders of the engineering the agency is doing to prepare for its future missions to Mars. In this case the press release described a new exercise device, dubbed ROCKY (for Resistive Overload Combined with Kinetic Yo-Yo), for use in the Orion capsule.

“ROCKY is an ultra-compact, lightweight exercise device that meets the exercise and medical requirements that we have for Orion missions,” said Gail Perusek, deputy project manager for NASA’s Human Research Program’s Exploration Exercise Equipment project. “The International Space Station’s exercise devices are effective but are too big for Orion, so we had to find a way to make exercising in Orion feasible.

As is their habit these days in their effort to drum up support for funding for SLS and Orion, the press release was filled with phrases and statements that implied or claimed that Orion was going to be the spacecraft that Americans will use to explore the solar system.

…engineers across NASA and industry are working to build the Orion spacecraft and Space Launch System rocket that will venture to deep space for the first time together…

…Over the next several years, NASA’s Human Research Program will be refining the device to optimize it not only for near-term Orion missions with crew, but for potential uses on future long-duration missions in Orion…

These are only two examples. I have clipped them because both were very carefully phrased to allow NASA deniablity should anyone question these claims. For example, in the first quote they qualify “deep space” as specifically the 2018 unmanned lunar test flight. And the second quote is qualified as referring to missions to lunar space. Nonetheless, the implied intent of this wording is to sell Orion as America’s interplanetary spaceship, destined to take us to the stars!

Don’t believe me? Then take a look at NASA’s own Orion webpages, starting with the very first words on their Orion Overivew page.

Proposed House NASA budget flat, with some surprising support for Artemis

8:51 am

While the first House proposal for NASA’s 2021 budget has rejected the Trump administration’s request for a total $3 billion increase for the agency to fund Artemis so that it can complete a manned mission to the Moon by 2024, it also provided about 18% of the funds requested for building the manned lunar lander required for that mission.

Back in February, the White House asked for $3.37 billion in fiscal year 2021 to accelerate development of the lander.

Democrats in the House have been skeptical of the 2024 launch date—some see it as political due to the timing of the next presidential election—and so have been slow to fund the lander. In its budget, the House appropriates $1.56 billion for “Exploration Research and Development.” This includes funding for the lander, Lunar Gateway, and other activities related to the Moon’s surface, of which more than $600 million can be used for the lander.

The House also provided a boost of $343 million to SLS.

My guess is that the Democrats in the House are working to keep Artemis going because of the jobs it brings to their districts, but want to slow it down enough so that it cannot succeed while Trump is in office. Thus, the release of some funds for the lunar lander, but not enough to build it, now.

The House proposal also includes a loosening on Congress’s mandate that Europa Clipper must launch on SLS. NASA is now given the option to consider other alternatives if SLS is not avaiable, which means that NASA can now consider using the Falcon Heavy instead.

This proposal must still pass the Republican-controlled Senate, so expect more changes.

NASA awards Northrop Grumman contract for more SLS solid rocket boosters

9:50 am

NASA today awarded Northrop Grumman a $49.5 million contract to begin work on twelve more SLS solid rocket boosters, enough for six more SLS flights.

Under this letter contract, with a potential value of $49.5 million, NASA will provide initial funding and authorization to Northrop Grumman to order long-lead items to support building the twin boosters for the next six SLS flights. Northrop Grumman will be able to make purchases as the details of the full contract are finalized within the next year. The full Boosters Production and Operations Contract is expected to support booster production and operations for SLS flights 4-9. The period of performance for the letter contract is 150 days; the definitized contract will extend through Dec. 31, 2030.

I especially like the headline Doug Messier used today in his post of NASA’s press release of this award at Parabolic Arc: “NASA Sinks More Money into SLS.” An apt description, since the odds of this program continuing to 2030 as described is quite low. The cost is too high, and other more capable and less expensive rockets will be available in the next few years, making SLS the equivalent of the buggy whip. Any money NASA spends on it now is essentially cash the agency is wasting.

NASA tests SLS backup tank to failure

6:17 pm

In preparation for the only planned full scale static fire engine test of the core first stage of the SLS rocket, NASA engineers have successfully completed a tank test to failure on a back-up oxygen tank.

The tank was filled with water to simulate the oxygen, and cracked as expected at the predicted pressure and at the predicted weld. A short 11-second video of the moment of failure test is embedded below the fold.

This test illustrates the methods by which NASA works. Unlike SpaceX, which is doing similar tests at the very beginning of its Starship design stage to best improve their design, NASA does this testing at the very end of construction, to prove that what they have built will work. The former method in the long run is less risky and faster, as SpaceX quickly finds out what works and doesn’t and builds accordingly.

The latter method is more risky because it depends on complex computer models, which can always be wrong. It also is more expensive in that it requires NASA to build its rockets with large margins of error, just in case those models are wrong. Finally, it appears to take longer to build, because of those required large margins of error. Your rocket or spaceship needs almost to be “gold-plated” to make sure it will work, when completed, since you really can’t test it in the design phase and build it more efficiently based on those tests.

The coming final flight of the shuttle’s solid rocket booster segments

8:55 am

Link here. As NASA begins the assembly process for its first long-delayed SLS launch sometime in the next year. the article at the link outlines in detail the space shuttle history of the many reused segments used to build the rocket’s two solid rocket boosters.

All together, the Artemis I solid rocket booster segments previously helped launch 40 space shuttle missions dating back 30 years.

The oldest cylinder, which will fly as part of the booster mounted on the right side of the SLS core stage, first lifted off on the STS-31 mission with the Hubble Space Telescope on April 24, 1990. It was then used for six more shuttle flights, including Endeavour’s debut on STS-49 in 1992 and STS-95 in 1998, which lifted off with Mercury astronaut and senator John Glenn as part of its crew.

Other notable missions that are part of the Artemis 1 boosters’ legacy include: STS-71, which marked the first shuttle docking with the Russian space station Mir in 1995; STS-93, which deployed the Chandra X-ray Observatory and marked the first spaceflight commanded by a woman, Eileen Collins, in 1999; STS-114, the return to flight after the loss of the space shuttle Columbia in 2005; and STS-133, the final launch of the space shuttle Discovery in 2011.

The hardware also includes new components, including the two forward domes, two cylinders and four stiffeners.

This first SLS launch however will be the last time these segments will fly. Unlike the shuttle, NASA is making no effort to recover and reuse these boosters.

The shuttle effort to reuse these booster segments was never really very cost effective, so not reusing them on SLS might actually save money. Those savings however are chicken feed when compared to SLS’s overall cost. The problem really is with SLS’s fundamental design: cumbersome, slow, expensive, and difficult to use.

NASA considering consolidating two Gateway launches into one

9:16 am

Capitalism in space: NASA’s Artemis program is now considering using a single launch to place two different Gateway modules into space, rather than two separate launches.

Originally, NASA wanted to launch the PPE and HALO modules – together representing the absolute bare minimum needed to build a functional Gateway – on separate commercial rockets in 2022 and 2023, respectively. Now, according to NASA associate administrator Doug Loverro, the space agency has made the decision to launch both modules simultaneously on the same commercial rocket.

This decision was made in large part because it makes sense from a technical simplicity and overall efficiency standpoint but also because several commercial launch vehicles – either currently operational or soon to be – are set to debut extremely large payload fairings. As a combined payload, the Gateway PPE and HALO modules would be too big for just about any existing launch vehicle, while the tiny handful it might fit in lack the performance needed to send such a heavy payload to the Moon.

Falcon Heavy apparently has the performance needed, as NASA used the rocket and a new stretched fairing developed by SpaceX for military customers as a baseline to determine whether PPE and HALO could launch together. Given that NASA could have technically used any of the vehicles expected to have large payload fairings for that analysis, the explicit use and mention of Falcon Heavy rather strongly suggests that the SpaceX rocket is a front runner for the new combined launch contract. This isn’t exactly surprising, given that the massive rocket has already completed three successful launches and will attempt at least another four missions between now and 2023.

Note the rocket that is not mentioned: SLS.

My regular readers know my consistent opposition to Gateway. That opposition was based on its initial design, depending for launch and operations entirely on NASA’s SLS rocket, and requiring it to be built before we landed on the Moon. Based on the SLS program’s track record, I believed Gateway would become, like SLS, nothing more than a pork barrel project accomplishing nothing but funneling government payroll to congressional districts while failing to launch any missions into space.

If NASA however is shifting gears, and aiming to allow private enterprise to build, launch, and operate Gateway, for considerably less cost and time, than Gateway might actually be of some value, mostly because there is actually a chance it might really be built, within a few short years.

I remain skeptical however. I still have questions about this lunar station’s utility, at this time. We might be spending a lot of money for a space station that won’t get us anywhere. Or maybe if NASA rethinks it properly it could provide us the real opportunity to test construction of an interplanetary spaceship, in lunar orbit.

We will have to see how this plays out. This story does appear encouraging however.

Successful static fire Raptor engine test on 4th Starship prototype

9:19 am

Capitalism in space: SpaceX yesterday successfully completed the first static fire Raptor engine test on its fourth Starship prototype, laying the foundation for a planned 150-meter vertical hop later this month.

The test lasted about three seconds.

I want to make a quick comparison between SpaceX’s approach for developing Starship, and NASA’s development of SLS. The differences are stark.

First, SpaceX began cutting metal a little over one year ago, and is already testing a full scale prototype, fully fueled, with its planned flight engine.

SLS began development officially around 2011. It uses the engines from the Space Shuttle, so those are already flight proven. However, even after almost a decade of development NASA as yet to do a single static fire test with those engines actually installed on an SLS rocket, either a prototype or the real thing.

Second, in the past year SpaceX has been aggressively testing the fueling of Starship, using a series of prototypes. With this fourth iteration they have apparently gotten the fueling process and the tanks to work effectively. Further tests of course will increase their confidence in the system’s reliability.

SLS, even after almost a decade of development, has yet to do any similar tank tests. Instead, NASA has done separate individual tests of the rocket’s tanks, but never with everything fully assembled. The agency, and its lead contractor Boeing, hope to finally do their first full scale SLS tank test and static fire test sometime later this year. As they have never filled the tanks in this manner before, they have admitted that problems could arise, including the possibility that the tanks could leak.

Note the big difference. SpaceX has done this testing very early in development. NASA is doing it very late in development. Which to you seems the better approach?

NASA buys 18 new space shuttle engines for SLS for $1.79 billion

8:09 am

NASA has awarded Aerojet Rocketdyne a $1.79 billion contract to build 18 new space shuttle R-25 engines for its still unlaunched SLS rocket.

In plain math, that equals $100 million per engine. Since SLS uses four of these engines per launch, and since that rocket is entirely expendable and will thus throw these engines away after each launch, that guarantees each SLS launch must cost no less than $400 million, about four times the price of a Falcon Heavy launch.

But wait, there’s more! Eric Berger at Ars Technica notes

NASA has previously given more than $1 billion to Aerojet to “restart” production of the space shuttle era engines and a contract for six new ones. So, according to the space agency, NASA has spent $3.5 billion for a total of 24 rocket engines. That comes to $146 million per engine. (Or 780,000 bars of Gold-Pressed Latinum, as this is a deal only the Ferengi could love.)

That means each SLS launch must cost a minimum of just under $600 million, and that’s just the price for the four engines. It doesn’t include the rocket itself, the ground systems, its upper stages, or any other component.

But wait, there’s more! Berger also reminds us that SpaceX estimates the cost to build each its Starship Raptor engines to be about $1 million, and each will be used multiple times. He also points out that the Raptor is actually more powerful than the R-25 engine.

That’s okay though. This is the federal government, run by Washington, whose goal for the few decades has been to let no project succeed, and to waste as much money as possible in the process. And if they can squelch the dreams and aspirations of everyone else as they do it, so much the better!

NASA delays 1st SLS launch again

9:55 pm

NASA has now made official what had been expected for months, announcing a new delay of the first unmanned test flight of its SLS rocket from March 2021 to November 2021.

The article tries to put a lot of the blame for this new delay on the shut down over the Wuhan panic, but that shut down will only stop work for at most two months. The new delay however adds eight months to the schedule, showing that they probably were never going to meet that March 2021 deadline, and are using COVID-19 as a cover for the program’s continuing problems, delays, and cost overruns.

Should this unmanned flight take place in November 2021, it will have taken NASA about seventeen years and about $60 billion to get to that first flight. They say the first manned mission is scheduled in late 2022 or early 2023. If true would mean it took NASA about two decades to achieve a single manned flight since Bush Jr. proposed it.

Of course, that is making the very unlikely assumption that there will be no further delays before that first manned flight. I personally am very confident there will be.

Curiosity and other Mars orbiters threatened by budget cuts

9:25 am

The proposed budget for NASA in the Trump administrations 2021 budget request to Congress includes significant budget cuts to both Curiosity and several Mars orbiters needed to act as relay communications satellites.

The White House’s 2021 federal budget request allocates just $40 million to the mission, a decrease of 20% from the rover’s current funding. And that current funding is 13% less than Curiosity got in the previous year, said Curiosity project scientist Ashwin Vasavada, of NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California.

If the 2021 request is passed by Congress as-is, Curiosity’s operations would have to be scaled back considerably. Running the mission with just $40 million in 2021 would leave unused about 40% of the science team’s capability and 40% of the rover’s power output, which comes from a radioisotope thermoelectric generator (RTG), Vasavada said.

In addition, the proposed budget will require a 50% reduction in imaging by Mars Reconnaissance Orbiter, the end to the Mars Odyssey orbiter, and a significant but unspecified reduction in the use of the MAVEN orbiter.

I reported these facts back in March but there is no harm in noting them again.

The question is not whether there should be cuts at NASA. Considering the overall federal debt and annual budget deficit, NASA’s budget should be cut. The question is what to cut. The planetary program, probably NASA’s most successful program, is certainly not the program to cut. Instead, the Trump administration should be cutting the waste and badly run programs, like SLS, that spend billions and accomplish nothing.

If Congress and Trump did this, they could cut NASA’s total budget and still have plenty left over for the commercial manned program — including going to the Moon — and also increase the budget to the planetary program. I’ve been saying this since 2011, and nothing has happened in the past decade to change that conclusion.

New technical problems for SLS?

10:49 am

A new GAO report [pdf] issued yesterday has revealed that SLS engineers are concerned that the rocket’s core stage will develop leaks during its first full test, hopefully scheduled for this year.

[T]he new “Assessments of Major NASA Projects” report released on Wednesday contains what seems to be an entirely new bit of information about the Space Launch System rocket NASA is developing for deep space exploration. The report asserts that engineers at NASA and the SLS rocket’s core-stage contractor, Boeing, are concerned about fuel leaks.

Earlier this year, NASA moved the big rocket’s core stage to a test site at Stennis Space Center in southern Mississippi. Before the COVID-19 pandemic temporarily halted work, NASA and Boeing teams were working toward a critical summer exercise. During this “green run” test, the clamped-down rocket will ignite its engines and burn for about eight minutes to simulate an ascent into orbit.

“Program officials indicated that one of the top remaining technical risks to the green run test is that the core stage may develop leaks when it is filled with fuel,” the report states on page 82. “According to these officials, they have conducted extensive scaled testing of the gaskets and seals used in the core stage; however, it is difficult to precisely predict how this large volume of liquid hydrogen will affect the stage.”

My god, for them to think that the core stage might leak when it is filled with fuel for the first time illustrates the entire bankrupt nature of this entire project. This is why you do tank tests early in the process (as SpaceX has been doing with Starship), so that you don’t get surprised late in the game.

The report also notes further issues with the Orion capsule.

The Orion program plans to reduce the 7-month-long pre-launch processing period by 1.5 months. The program plans to use a mass simulator—instead of the Orion spacecraft—to conduct some prelaunch tests that would otherwise be done after integrating Orion with SLS—providing the program with extra time to complete work before delivering Orion for integration and further testing according to officials. With this shortened process, the program has only 1 week of schedule reserve remaining to the November 2020 launch date, and program officials have said this date will likely be delayed

I must remind everyone that Lockheed Martin got the contract to build Orion in 2005. They have had fifteen years to build this one capsule, and will still deliver it late.

Personally, I hope SLS leaks. If it does, it will force a very long new delay to the program, and very well might finally force Congress and the Trump administration to face reality and cancel it.

NASA awards SpaceX deal to provide cargo to Gateway

4:30 pm

Capitalism in space: Should NASA ever decide to build its proposed Gateway space station in orbit around the Moon (the odds of which have gone down recently), it announced today that it has signed a deal with SpaceX to use its Falcon Heavy rocket and an upgraded larger version of its Dragon capsule to ship cargo to that station.

The deal calls for at least two missions, and is SpaceX’s first deal in NASA’s Artemis program.

This deal is a major blow to SLS and Boeing, which up to now had a monopoly on all launches to supply and launch Gateway. In fact, Gateway was invented by Lockheed Martin, Boeing, and NASA (not Congress) in order to justify SLS’s existence. That NASA has now decided it is better off using the much cheaper and already operational Falcon Heavy for some Gateway missions suggests that SLS is increasingly vulnerable to cancellation. NASA is making it obvious that other commercial options exist. No need to wait years and spend billions for SLS, when they can go now, for much less.

NASA shuts down all in-house work, suspending SLS/Orion testing

8:38 am

In its panicky response to COVID-19, NASA is now requiring all workers to work from home, forcing the agency to suspend all in-house testing of SLS and Orion hardware.

NASA will temporarily suspend production and testing of Space Launch System and Orion hardware. The NASA and contractors teams will complete an orderly shutdown that puts all hardware in a safe condition until work can resume. Once this is complete, personnel allowed onsite will be limited to those needed to protect life and critical infrastructure.

We realize there will be impacts to NASA missions, but as our teams work to analyze the full picture and reduce risks we understand that our top priority is the health and safety of the NASA workforce.

This guarantees further delays to the first Artemis unmanned launch sometime in 2021. It also is par for the course for NASA’s entire effort to build this rocket. In just the past two weeks three different blistering inspector general reports have blasted different components of this project at NASA (overall management, construction of the launch systems, and development of software), proving that out-of-control cost overruns and endless delays in building SLS and Orion have been systemic throughout the agency.

Now they have shut down testing, even though the Wuhan virus is probably going to end up no more dangerous than the flu (now that treatment options exist).

NASA’s inspector general finds more budget overruns at Artemis

9:49 am

A new report [pdf] released today from NASA’s inspector general has found more budget overruns and managerial issues relating to developing the ground software required by both Orion and SLS.

There are two software components involved, called SCCS and GFAS for brevity. This report focuses on the latter. A previous report found that “SCCS had significantly exceeded its initial cost and schedule estimates with development costs increasing approximately 77 percent and release of a fully operational version of the software slipping 14 months.” According to that previous report [pdf], that increase went from $117 million to $207 million.

As for GFAS:

Overall, as of October 2019 GFAS development has cost $51 million, about $14 million more than originally planned.

This report, as well as yesterday’s, are quite damning to the previous management of NASA’s manned program under Bill Gerstenmaier. It appears they could not get anything done on time and even close to their budget.

It also appears to me that the Trump administration has removed the reins from its inspector general offices. During the Obama administration I noticed a strong reticence in IG reports to criticize government operations. Problems as outlined in both yesterday’s and today’s reports would have been couched gently, to obscure how bad they were. Now the reports are more blunt, and are more clearly written.

Also, this sudden stream of releases outlining the problems in Artemis might be part of the Trump administration’s effort to shift from this government program to using private commercial companies. To do this however the administration needs Congressional support, which up to now has strongly favored funding SLS and Orion. Having these reports will strengthen the administration’s hand should it propose eliminating these programs, as it is now beginning to do with Gateway.

More overruns in NASA’s SLS program, this time with the mobile launchers

9:46 am

A new inspector general report [pdf] has found massive cost overruns in NASA over the building of the two mobile launch platforms the agency will use to launch its SLS rocket.

The original budget for the first mobile launch was supposed to be $234 million. NASA has now spent $927 million.

Worse, this platform will see limited use, as it was designed for the first smaller iteration of SLS, which NASA hopes to quickly replace with a more powerful version. Afterward it will become obsolete, replaced by the second mobile launch platform, now estimated to cost $486 million.

That’s about $1.5 billion just to build the launch platforms for SLS. That’s only a little less than SpaceX will spend to design, test, build, and launch its new Starship/Super Heavy rocket. And not only will Starship/Super Heavy be completely reusable, it will launch as much if not more payload into orbit as SLS.

But don’t worry. Our geniuses in Congress will continue to support SLS no matter the cost, even if it bankrupts NASA and prevents any real space exploration. They see its cost overruns, long delays, and inability to accomplish anything as a benefit, pumping money into their states and districts in order to buy votes.

New inspector general report slams NASA’s SLS management

10:20 am

A new report [pdf] by NASA’s inspector general released today harshly slams the management of NASA for the never-ending cost overruns and scheduling delays that have plagued the agency’s effort to build and launch the Space Launch System (SLS).

From the report’s introduction:

Based on our review of SLS Program cost reporting, we found that the Program exceeded its Agency Baseline Commitment (ABC)—that is, the cost and schedule baselines committed to Congress against which a program is measured—by at least 33 percent at the end of fiscal year 2019, a figure that could reach 43 percent or higher if additional delays push the launch date for Artemis I beyond November 2020.

… [T]he SLS Program now projects the Artemis I launch will be delayed to at least spring 2021 or later. Further, we found NASA’s ABC cost reporting only tracks Artemis I-related activities and not total SLS Program costs. Overall, by the end of fiscal year 2020, NASA will have spent more than $17 billion on the SLS Program—including almost $6 billion not tracked or reported as part of the ABC.

The graph below, taken from page 45 of the report, illustrates the management failures here quite starkly.

SLS likely launch mid- to late-2021

9:33 am

According to comments by one NASA official last week, the first flight of SLS will likely not occur until the middle or late 2021, a further delay than the most recent prediction of April 2021.

NASA Associate Administrator Steve Jurczyk said on Friday that the first launch of the Space Launch System (SLS) with an uncrewed Orion spacecraft, Artemis I, will take place in mid-late 2021. He also said NASA will award contracts “within weeks” for the Human Landing System (HLS) as NASA strives to meet the Trump Administration’s goal of landing astronauts on the Moon by 2024 — the Artemis program. Embracing Artemis is the first step towards a trillion dollar cislunar space economy according to space industry executive Tory Bruno who spoke at the same conference in Laurel, MD. He urged everyone to stop “squabbling” and support the program.

There is a lot more in the article, including a lot of advocacy by Jurczyk and others for Lunar Gateway. I also found certain aspects of the Trump administration’s effort to make their 2024 target date for manned lunar landing, specifically related to the quick development of that Human Landing System (HLS), somewhat concerning:

We can’t thrash on the requirements. So on HLS, we said 90 days, we’re going to nail down the requirements. And if we can’t agree, NASA’s just going to tell you, use ours. We’re going to negotiate technical standards. Either use ours or show equivalency to yours, but after 90 days if we can’t get agreement, you’re going to use ours. … 90 days and we’re done with Human Landing System requirements.

I am all for doing it fast but one needs to also do it smart. I wonder about this approach.

Jurczyk noted that the administration and NASA are doing a lot of work outlining their plans for the whole Artemis exploration program following that lunar landing, and hope to reveal it by the end of March. Since this program still remains unfunded by Congress, that announcement will be part of the political campaign to obtain those funds.

More SLS launches planned/proposed?

9:48 am

According to this article from Ars Technica, NASA is considering shifting gears in its Artemis lunar program to become more dependent on SLS rather than a mix of SLS and commercial rockets.

The new plan, if implemented, would substantially cut commercially developed rockets—such as SpaceX’s Falcon Heavy and Blue Origin’s New Glenn—back from the Artemis program. Previously, NASA had said it would launch elements of its Human Landing System on commercial rockets, because such vehicles cost much less than the estimated $2 billion rate per launch of the SLS vehicle. Now, perhaps, private rockets may be called upon to launch smaller pieces such as a lunar rover to the Moon’s surface.

The source document, which appears to be very preliminary and which NASA calls “inaccurate”, also calls for four SLS launches leading up to the 2024 lunar landing, something that seems very very unlikely. Not only would it require Boeing to move faster in building additional SLS rockets, something the company has routinely been unable to do, this schedule assumes funding from Congress for SLS, something that remains unclear.

It also appears from the proposed launch schedule that Lunar Gateway is fading from view. This makes great sense, as the Gateway only causes delays and higher costs for any lunar landing program, something the Trump administration clearly wishes to avoid.

First SLS launch pushed back again to April 2021

9:15 am

NASA on February 20, 2020 finally admitted that the first SLS launch cannot happen in 2020, and set a new target date no earlier than April 18, 2021.

The previous target launch date in November 2020 was always a pure fantasy. NASA just held off admitting it in order to defuse any political consequences for having a program, building SLS, that will end up taking them almost two decades to complete.

This new launch date is likely the most realistic so far, since the hardware for SLS is actually finally coming together. Nonetheless, if anything at all should go wrong along the way, especially with the full static test firing of the core booster of the first stage scheduled for no earlier than August, then expect more delays, possibly lasting years.

Europa Clipper faces budget overruns

10:25 am

NASA’s $4.25 billion dollar mission to orbit the Jupiter moon Europa now faces cost overruns that threaten its launch in 2023.

The management of NASA’s Europa Clipper mission, facing dwindling cost reserves while still years away from launch, is looking at cost saving options that would preserve the mission’s science.

In a Feb. 3 presentation at a meeting of the Outer Planets Assessment Group in Houston, Jan Chodas, project manager for Europa Clipper at the Jet Propulsion Laboratory, said she was looking for ways to restore cost reserves that had declined precipitously in the last year.

Chodas said that Europa Clipper had met a JPL recommendation of 25% cost reserves, known at the lab as unallocated future expenses (UFE), when it completed a final “delta” preliminary design review in June 2019. By November, though, those reserves had fallen to just 12%, a level deemed “unacceptably low” for a mission not scheduled for launch until at least 2023.

To save money, they are “streamlining hardware testing and scaling back work on flight spare hardware. The project has also reduced the frequency of meetings of the mission’s science team.”

When the reserves in a government budget get this low, it almost always guarantees that the budget will go over. When the reserves get this low this early in the project, it almost always guarantees that the budget will go over, by a lot.

There have been other indications that Europa Clipper’s budget is in trouble. In March NASA canceled one science instrument to save money.

Making matter worse has been our lovely Congress, which has required this mission fly on its bloated, over-budget, and behind schedule SLS rocket, a mandate that is also costing the project an additional $1.5 billion (for the launch) while threatening its launch date (because of SLS delays). NASA would rather have the option to launch Clipper on the more reliable commercial and already operational Falcon Heavy, for about $100 million, thereby saving more than a billion dollars while guaranteeing its launch date. Congress so far has refused to budge, and has in fact insisted that the mission be delayed several years if necessary for getting it on SLS.

Meanwhile, Clipper itself is doing what too many big NASA projects routinely do, go overbudget.

Our federal government. Doesn’t its management skills just warm your heart?

House authorization bill focuses on pork

9:06 am

A new House authorization bill for NASA would shift the agency’s focus from commercial space and getting to the Moon to building Artemis and Gateway and going to Mars.

A NASA authorization bill released by the House Science Committee Friday proposes major changes to the direction of the agency’s human spaceflight programs, with a goal to land crews on the moon by 2028, not the 2024 schedule set by the Trump administration.

The House version for NASA Authorization Act of 2020, which would set NASA policy if enacted into law, calls for the space agency to develop plans for sending a crewed mission to orbit Mars by 2033.

The bipartisan legislation would appear to stand in the way of any plans to build a permanently-occupied moon base or develop methods to mine water ice inside craters at the moon’s poles, which could be converted into breathing oxygen, drinking water and rocket fuel.

The bill, not yet approved by the House committee despite support from the committee heads from both parties, differs significantly from the Senate bill, which places more emphasize on having NASA use private enterprise. For example while the Senate bill calls for NASA to hire privately-built lunar landers, the House bill wants NASA to build the landers entirely.

Read the whole article. The House bill could I think also be labeled the “Orange Man Bad for Space” bill, as it clearly seems designed to block almost all of the Trump initiatives to encourage private space and get a manned mission to the Moon sooner rather than later.
