NASA nixes plan to fly humans on first SLS flight

3:33 pm

Common sense prevails! In a joint decision with the White House, NASA announced today that they will not fly humans on the first test flight of SLS, now scheduled for sometime in 2019.

Bill Gerstenmaier, NASA associate administrator for human exploration and operations, said that the study turned up fewer technical issues with putting a crew on EM-1 than he originally expected. “What I was surprised by was that I thought there would be a whole lot of really negative work that would actually maybe make this not very attractive to us,” he said. “But when [acting NASA administration Robert Lightfoot] and I look at this overall, it does add some more risk to us, because it’s the first crew on the vehicle,” he said. The work to add crew to EM-1 would have cost NASA an additional $600–900 million, and delay the launch likely to the first or second quarter of 2020.

“The culmination of changes in all three of those areas said that overall, probably the best plan we have is actually the plan we’re on right now,” Gerstenmaier said. “When we looked at the overall integrated activity, even though it was feasible, it just didn’t seem warranted in this environment.”

The announcement also included an admission by Gerstenmaier that the first manned SLS flight, now set for 2021, will likely be delayed.

SLS oxygen tank dome dropped and damaged

11:46 am

You can’t make this stuff up. The dome for the oxygen tank for NASA’s SLS rocket has been accidently dropped and has been damaged beyond repair.

No details yet. It appears they can build another dome from available parts, but this will likely cause additional delays to the SLS launch schedule.

Update: More information here.

The damage was limited to the one dome section of the tank, which was not yet welded to the rest of the tank. “Assessments are ongoing to determine the extent of the damage,” she said. Henry said that the incident was classified as a “Type B” mishap. Such a mishap, according to NASA documents, covers incidents that cause between $500,000 and $2 million in damage. No one was injured, she said.

The liquid oxygen tank involved in the incident was a qualification model, intended for testing, and not flight hardware. Henry said it wasn’t immediately clear how long the investigation would take.

Brittle and weak welds on SLS tanks?

8:39 am

Government in action! The hydrogen tanks that will be used for the first SLS rocket flight were welded using a technique that NASA has since found to be untrustworthy.

Although the weld strength issue stopped welding the qualification and flight articles of the LOX tank before it could start, the issue wasn’t caught until after both LH2 tanks were welded with the modified pin tool last summer. The implications of the two tanks possibly having below design strength welds disrupted the original, post-weld plans.

The LH2 qualification tank, which will be used for structural testing at Marshall Space Flight Center in Huntsville, Alabama, was welded first and after setup and configuration was taken to Building 451 in December of last year both for proof testing of the welds and to qualify the test facility and procedures for subsequent flight tanks. Hydrogen tanks are proof tested by pressurizing them with nitrogen gas while a hydraulic test rig applies loads to the structure. “We wanted to wring out…the control system – 451 was another building that was made bigger to fit the hydrogen tank,” Doering said. “The control system is all new, the reaction fittings are all new, along with all the actuators. We didn’t want to put the flight asset in there to try to use it for the first time, so [using] the qual[ification] article [first] was also trying to wring out the pressurization and the actuation of the control system in 451.”

Originally, the plan included a test case to pressurize the qualification tank to slightly above flight pressure to help as a part of that “pathfinding” work; however, the discovery that the welds may be below design strength forced plans to be reconsidered.“We couldn’t say with any real degree of certainty that these welds would make it to [flight pressure],” Doering said. “In a pneumatic test, pressurizing it like that, it’s like a balloon…there’s a good portion of the community that thinks it will survive, there’s another portion of the community that says you don’t know enough to be able to say that, [and] there’s another portion of the community that says…’no way.’ [emphasis mine]

This is merely the qualification tank, built to find out if the tank design, which appears to be overly complicated to begin with, will work. The flight tank?

Lower pressure isn’t an option for the LH2 flight tank, which must perform at flight pressures both in testing and in flight. The SLS Program developed and is working on multiple, parallel options for consideration that include repairs and/or replacement of the already-welded flight tank. “We’re looking at use as-is – can I get to the point where I’m comfortable using that flight tank?” Doering said. “The answer to that is probably not, just because the analysis tools don’t exist yet to do this.” [emphasis mine]

They are faced with the likely possibility that they will have to repair the tank, which will likely cause the now 2019 launch date for the first unmanned test to be delayed further.

The rumors that NASA is considering making that first test flight a manned one makes me think that they are considering that decision as a cover for these additional delays. “We need more time to make this work as a manned flight,” NASA management will claim, using that extra time to fix the tanks as well. They will also claim they need more money, as they always do.

Meanwhile, NASA is having trouble building rocket tanks, an item that aerospace engineers figured out how to build half a century ago. Way to go, NASA!

NASA may have decided to fly humans on first SLS test flight

8:32 am

Doug Messier at Parabolic Arc has a story today suggesting that there are rumors at NASA that the agency has decided that it will put astronauts in Orion for SLS’s first test flight, now tentatively scheduled for sometime in 2019.

At he notes, this will only be the second time in history humans will have flown on a untested rocket, the first being the space shuttle, where they had no choice as the vehicle needed people to fly it.

NASA’s arguments in favor of this manned test flight will probably rest on noting how much of the rocket is based on previously flown equipment. For example, the upper stage for this flight will be a modified Delta upper stage, a well tested and frequently flown stage. The first stage will be made of side-mounted first stage solid rocket boosters that are essentially upgrades of the shuttle’s solid rocket boosters. And the first stage engines are actual shuttle engines salvaged from the shuttle’s themselves. In addition, NASA will note that Orion will have a launch abort system, though it appears that there will be no test of this system prior to the flight.

These arguments don’t carry much weight. The Delta upper stage will also be modified for this flight, and this will be that version’s first use. Similarly, the solid rocket boosters have been modified as well, and this will be their first flight. And as I noted, the Orion launch abort system will not have been tested in flight.

Finally, and most important, the goal of this test flight is to see if these different parts have been integrated together properly. As a unit, none of them has ever flown together. To put humans on such a flight is very foolish indeed.

Messier sums this up quite well:

The flight might come off just fine. But, I fear that NASA’s concern about keeping the program funded, and Donald Trump’s desire for some space spectacular to boost his re-election chances, could combine to produce something very unfortunate.

I pray that people in the Trump administration put a stop to this silliness, as soon as possible.

NASA officially delays SLS first flight to 2019

12:40 pm

Government in action! Despite spending almost $19 billion and more than thirteen years of development, NASA today admitted that it will have to delay the first test flight of the SLS rocket from late 2018 to sometime in 2019.

“We agree with the GAO that maintaining a November 2018 launch readiness date is not in the best interest of the program, and we are in the process of establishing a new target in 2019,” wrote William Gerstenmaier, chief of NASA’s human spaceflight program. “Caution should be used in referencing the report on the specific technical issues, but the overall conclusions are valid.”

Anyone who is a regular reader of Behind the Black will not be surprised by this. Beginning as far back as March 2015 I began noting the various issues that made a 2018 launch unlikely. All that has happened here is that NASA has gone public with what has been obvious within the agency now for two years.

The competition between the big government SLS/Orion program and private commercial space is downright embarrassing to the government. While SLS continues to be delayed, even after more than a decade of work and billions of wasted dollars, SpaceX is gearing up for the first flight of Falcon Heavy this year. And they will be doing it despite the fact that Congress took money from the commercial private space effort, delaying its progress, in order to throw more money at SLS/Orion.

NASA to rely more on private space for deep space missions

12:52 pm

Capitalism in space: NASA officials stated this weekthat they plan to rely more on private space companies for its future deep space missions.

NASA’s statement is the most direct agency indication so far that projected U.S. government funding may need to leverage private-sector investments and commercial expertise in order for crews to fulfill the agency’s target of reaching Mars by the late 2030s and establishing settlements there by the 2040s. NASA said it also expected to persuade some foreign governments to participate in crewed voyages to Mars.

William Gerstenmaier, the head of NASA’s human-exploration office, wrote to the inspector general that efforts to use private cargo rockets as part of the overall drive to send crews to Mars “are continual and will also be reflected in the exploration road map” slated for delivery to Congress at the end of 2017.

This story is merely noting NASA’s response to the recommendations of the NASA inspector general report [pdf] that came out earlier in the week that noted the delays and costs of SLS/Orion and suggested alternative approaches. What that response indicates is that NASA is increasingly bending to the cost pressures that they face with SLS/Orion, and are now more willing to consider private and less expensive and quicker alternatives.

The Inspector General (IG) report is itself a sign that the agency and the executive branch is beginning to see the light about the ineffectiveness of SLS/Orion. Previous IG reports in the past five years have tiptoed around the delays and gigantic cost of SLS/Orion. If anything, they were written to allow NASA to prepare Congress and the public for more delays and larger budgets. This report however was much more blunt and critical, and went out of its way to outline alternatives to SLS/Orion.

Another sign that the political winds are shifting is this story about a request by 20 House members to the Air Force to expand its program encouraging the development of competing private launch systems. In the past some of these same House members had tried to force particular companies and products on the Air Force and on ULA. Now they seem more willing to let the Air Force put out the bids competitively and allow the chips to fall where they may.

More important is this quote about two members who did not sign the letter request:

Absent from the list of members who signed the [letter] are Reps. Mac Thornberry (R-Texas) and Mike Rogers (R-Ala.), the chairmen of the full House Armed Services Committee and its Strategic Forces Subcommittee, respectively. In February, the two sent a letter to Acting Secretary of the Air Force Lisa Disbrow and James MacStravic, performing the duties of the under secretary of defense for acquisition, calling on the government to have “full access to, oversight of, and approval rights over decision-making about any engine down-select for Vulcan (assuming they will be requesting government funding).”

In the letter, they argued that since ULA is accepting government funding to support the development of Vulcan, the government should also have insight into that process, “especially where one of the technologies is unproven at the required size and power.” That was a reference to Blue Origin’s BE-4, which will be the largest rocket engine developed to date using methane as a fuel, rather than the kerosene used by the RD-180 and AR1 engines.

Thornberry has since backtracked on the comments in that letter, telling reporters last month it was not his intent to micromanage subcontracting decisions.

Rogers, in a recent SpaceNews interview, said he was not satisfied with the pace of development of an RD-180 replacement, but also praised the capabilities of commercial launch companies. “My subcommittee, our full committee, this Congress, is committed to not stop until we have an American-made engine that can get our national security space assets launched,” he said. [emphasis mine]

That these congressmen appear to be backing off from pushing their favorite rockets or insisting that the Air Force micromanage the development of these private rocket engines is a positive sign. It appears that there is increasing political pressure to support private development, free of government control.

Audit finds SLS unlikely to launch in 2018

4:00 am

A NASA audit has found that it is unlikely that the first SLS test flight will take place as scheduled in 2018, and that the first manned flight is also likely to be delayed from its 2021 launch target.

“NASA’s first exploration missions — EM-1 and EM-2 — face multiple challenges that will likely delay their launch,” the report states. The missions “are not likely to launch by 2018 or 2021, respectively,” it continues.

When might a crew launch? Hard to say.

The report says incomplete NASA information makes it “more difficult for both the agency and external stakeholders to gain a full understanding of the costs of that mission or to assess the validity of the agency’s launch date assumptions.”

If the first manned flight happens in 2023, as now expected, it means that it will occur 20 years after George Bush first proposed the Crew Exploration Vehicle (Orion) and the heavy lift rocket to put it into space. The total cost to fly this one mission will be approximately $43 billion.

Let me repeat that: $43 billion and 20 years to fly a single manned mission. Does no one in government see something wrong with this picture?

SLS faces more delays

5:34 pm

Delays by ESA in the construction of the service module for Orion, plus the tornado damage at the Michoud facility in Louisiana, could force NASA to delay the first unmanned test launch of the SLS rocket, presently planned for late in 2018.

NASA is also considering delaying the flight further should the agency decide to make this first unmanned test flight a manned one. They also say they will need more money if they have to put people on the first flight. I guess $43 billion and almost 15 years wasn’t enough.

By the way, it took less than four years to win World War II. From Kennedy’s speech to the Apollo 11 landing was only eight years. One wonders when we, as a nation, will finally wake up and realize that SLS is not a rocket to the Moon, but an never-ending jobs program unable to accomplish anything in space.

Blue Origin proposes unmanned lunar mission

9:12 am

The competition heats up: Blue Origin has proposed building for NASA an unmanned lunar mission to visit Shackleton Crater at the Moon’s south pole by 2020.

The Post says the company’s seven-page proposal, dated Jan. 4, has been circulating among NASA’s leadership and President Donald Trump’s transition team. It’s only one of several proposals aimed at turning the focus of exploration beyond Earth orbit to the moon and its environs during Trump’s term.

As described by the Post, the proposal seeks NASA’s support for sending a “Blue Moon” lander to Shackleton Crater near the moon’s south pole. The lander would be designed to carry up to 10,000 pounds of payload. It could be launched by Blue Origin’s New Glenn rocket, which is currently under development, or by other vehicles including NASA’s Space Launch System or United Launch Alliance’s Atlas 5. [emphasis mine]

The important take-away from this story is not the proposal to go to the Moon, but the proposal, as highlighted, that other rockets could do it instead of SLS. Though the proposal includes SLS as a possible launch vehicle, NASA’s giant rocket simply won’t be ready by 2020. That New Glenn might be illustrates again how much better private space does things, as this rocket is only now beginning development. If it is ready by 2020, which is what Blue Origin has been promising, it will have taken the company only about four years to build it, one fourth the time it is taking NASA to build SLS.

ULA lets the press see part of SLS

9:38 am

Link here. The upper stage of SLS is undergoing its final testing in Michoud prior to shipment to Florida, and ULA had a press event to show it off.

“This is the first piece of integrated flight hardware for the SLS system to be shipped down to the Cape in preparation for our very first launch,” said Jerry Cook, Deputy SLS Program Manager for NASA. Cook noted that the ICPS test article is currently undergoing stress and load tests at Marshall.

The completion of the ICPS is yet another landmark in SLS’ development, though some contend it’s still a drawing-board vehicle. John Shannon, Boeing’s Vice President and General Manager of the SLS Program, disagrees. “The SLS has, in various forms, been called a paper rocket […] and, if I think you look to your right, you’ll see that absolutely is not true,” stated Shannon. “If you had the opportunity to go to the Michoud Assembly Facility in New Orleans, where we’re putting the bigger core stage together, you would also see that it is not true because we are putting hardware together as we speak.”

This upper stage engine is a brand new design and has never flown before, and the rocket it is part of has yet to be assembled. Yet NASA is considering flying humans on it during its first test flight, even as it harasses SpaceX and Boeing about using the Falcon 9 and Atlas 5 rockets, both proven repeatedly in operational flights, for their manned ISS missions.

The article also gives an update on the situation at Michoud since it was hit by a tornado on February 8. It appears that the facility is operating again, but not fully.

Killing both commercial space and American astronauts

9:54 am

This all reeks of politics: A new Government Accountability Office (GAO) report released yesterday says that NASA it should not permit Boeing and SpaceX to fly humans on their capsules and rockets until they fix certain issues and test both repeatedly on unmanned flights before the first manned flights to ISS.

This GAO report was mandated by Congress, and it requires NASA to certify that both Boeing and SpaceX have met NASA’s requirements before allowing those first manned flights. While the technical issues outlined in the report — to which NASA concurs — might be of concern, my overall impression in reading the report, combined with yesterday’s announcement by NASA that they are seriously considering flying humans on SLS’s first test flight, is that this process is actually designed to put obstacles in front of Boeing and SpaceX so as to slow their progress and allow SLS to launch first with humans aboard.

For example, the report lists three main problems with the commercial manned effort. First there is the Russian engine on the Atlas 5. From the report itself [pdf]:

Two congressmen propose naming SLS for astronaut Gene Cernan

9:43 am

Two congressman yesterday introduced legislation that would rename SLS after Eugene Cernan, the last Apollo astronaut to walk on the Moon.

I don’t think anyone would argue with this. First, SLS is a terrible name for the rocket. Second, Cernan deserves the recognition.

At the same time, I suspect this is happening as part of an overall push within the Washington community to sell SLS to Trump and his administration. This proposal, as well as the recent news stories proposing SLS/Orion Moon missions and putting astronauts on SLS’s first flight, all point to a lobbying effort inside NASA, Congress, and the big space community to save SLS, which when compared to the successes and achievements of commercial space since 2010 appears an abject failure.

That comparison is at the heart of my policy paper, Capitalism in Space, which will hit the newstands next week. It makes it very clear how much a failure SLS/Orion has been, and how embarrassing that failure stands when compared to commercial space.

NASA considers putting astronauts on first SLS/Orion flight

1:28 pm

Faced with indications that Trump wants a manned lunar mission during his first term, NASA’s acting administrator has asked his engineers and management to look into the possibility of putting humans on the first SLS/Orion launch, now set for late in 2018.

As the Acting Administrator, my perspective is that we are on the verge of even greater discoveries. President Trump said in his inaugural address that we will “unlock the mysteries of space.” Accordingly, it is imperative to the mission of this agency that we are successful in safely and effectively executing both the SLS and Orion programs.

Related to that, I have asked Bill Gerstenmaier to initiate a study to assess the feasibility of adding a crew to Exploration Mission-1, the first integrated flight of SLS and Orion. I know the challenges associated with such a proposition, like reviewing the technical feasibility, additional resources needed, and clearly the extra work would require a different launch date. That said, I also want to hear about the opportunities it could present to accelerate the effort of the first crewed flight and what it would take to accomplish that first step of pushing humans farther into space. The SLS and ORION missions, coupled with those promised from record levels of private investment in space, will help put NASA and America in a position to unlock those mysteries and to ensure this nation’s world pre-eminence in exploring the cosmos.

This is incredibly stupid. That first flight will be the very first time SLS will fly. It will also be flying with an upper stage engine that has also never flown before. It will take the Orion capsule to the Moon, when the capsule itself has not yet even done one orbit around the Earth. To put people on it makes no engineering sense at all.

Trump to the Moon!

8:46 am

Two stories in the past two days strongly suggest that the Trump administration is planning a two-pronged space policy approach, with the long-term goal of shifting most of space to private operations.

From the first link:

The more ambitious administration vision could include new moon landings that “see private American astronauts, on private space ships, circling the Moon by 2020; and private lunar landers staking out de facto ‘property rights’ for American on the Moon, by 2020 as well,” according to a summary of an “agency action plan” that the transition drew up for NASA late last month. Such missions would be selected through an “internal competition” between what the summary calls Old Space, or NASA’s traditional contractors, and New Space characterized by SpaceX and Blue Origin. But the summary also suggests a strong predilection toward New Space. “We have to be seen giving ‘Old Space’ a fair and balanced shot at proving they are better and cheaper than commercial,” it says.

Another thrust of the new space effort would be to privatize low-Earth orbit, where most satellites and the International Space Station operate — or a “seamless low-risk transition from government-owned and operated stations to privately-owned and operated stations.” “This may be the biggest and most public privatization effort America has ever conducted,” it says.

Essentially, they are going to do exactly what I suggested back in late December, give SLS/Orion a short-term realistic goal of going to the Moon. This is what it was originally designed for, and it is the only technology presently available that has even the slightest chance of meeting the three year deadline outlined above. More important, this will give Congress something in the negotiations, as SLS/Orion has been Congress’s baby — pushed and funded by Congress over the objections of the previous administration and without a clear mission to go anywhere — in order to keep the money stream flowing to the big “Old Space” companies like Boeing and Lockheed Martin. Obama tried to simply cancel its predecessor, Constellation, and that did not sit well with Congress. Trump however understands negotiation and how to play the game. In order to eventually eliminate SLS Trump is going to provide Congress some short term excitement and some viable long term alternatives.

The long term alternatives will be private enterprise. Even as they send SLS/Orion on its grand finale to the Moon, the Trump administration will accelerate the restructuring of NASA to make the agency less of a design and construction operation and more a mere customer of private space. All non-military Earth orbital operations will be shifted to the private sector over time, so that once SLS/Orion has achieved that goal of completing a lunar mission there will be a strong enough private space sector to replace it, allowing Congress to let it go the way of Apollo and the space shuttle.

NASA SLS/Orion facility in Louisiana sustains tornado damage

8:25 am

A tornado has damaged the building NASA uses at its Michoud facility near New Orleans for building SLS and Orion.

[One official] says a 43-acre building where they build rockets suffered significant damage on one end. A number of areas in the facility have lost parts of the roof or walls. He says the hardware and tooling used in the Orion and Space Launch System were not damaged. But they’ll have to do a “significant effort” to cover everything up and make sure any subsequent bad weather doesn’t affect it while the roof and walls are repaired.

Based on this report, this damage should not effect the SLS/Orion launch schedule. At least, if this was a private company it would not. We shall see how NASA responses.

NASA asteroid redirect mission delayed again

11:15 pm

Due to the uncertainty of its budget NASA has decided to delay the award of the contracts to begin work on its asteroid redirect mission (ARM).

The uncertainty is that Congress has never budgeted any real money for it. The mission was proposed by Obama but only vaguely, without any real support. First it was to be a manned mission to an asteroid, using Orion. Then it was to be an unmanned mission to bring a large asteroid closer to Earth to be later visited by astronauts in an Orion capsule. Then the large asteroid became a mere boulder, with the manned mission delayed until the unforeseen future.

I think NASA sees the writing on the wall here. They expect this vague unsupported mission to die with the next administration, and have decided it is better not to waste money on it now.

Trump interested in lunar manned mission?

3:48 pm

After meeting with Donald Trump a historian now says the president-elect appears very interested in the idea of sending a man to the Moon.

All of these stories continue to be speculation, but I strongly suspect that much of it also consists of trial balloons pushed by the various supporters of SLS/Orion in their effort to give that very expensive and so-far completely unproductive boondoggle a mission it can actually achieve. Right now, SLS/Orion has no mission. It is only funded through the first manned test flight in 2021 (likely to be delayed until 2023). Since it has been a pork barrel favorite of a number of Senators and Congressmen, I would not be surprised if they are trying to convince Trump to fund it by giving it a new Kennedy-like mission.

The ever shrinking and delayed Orion/SLS

6:15 pm

NASA is considering changing the first Orion crewed mission so that, instead of orbiting the Moon, the spacecraft will merely whip past it on a course that will take it directly back to Earth.

In a presentation to a Nov. 30 meeting of the NASA Advisory Council in Palmdale, California, Bill Gerstenmaier, NASA associate administrator for human exploration and operations, discussed what he described as a new proposal for Exploration Mission 2 (EM-2) that would last eight days. The concept, called the multi-translunar injection free minimum mission, would initially place the Orion spacecraft and its Exploration Upper Stage (EUS) into an elliptical orbit around the Earth with an apogee of 35,000 kilometers. After spending one day in that orbit, the spacecraft would separate from the EUS and use its service module engine for a final burn to send the spacecraft towards the moon. Orion would fly on a “free return” trajectory around the moon without going into orbit and without requiring another engine burn. The mission would end with a return to Earth eight days after launch, but with an option to extend the mission to up to 21 days.

The entire SLS/Orion project is idiotic and incredibly dangerous, not because it is going to the Moon but in how they plan on doing it, with literally no preparation flights beforehand. With Apollo, NASA was very careful to test each part of the package first, then proceed with a more ambitious mission. The only exception to this process was Apollo 8, which went to the Moon without a Lunar Module. That happened because they were in an intense space race with the Soviets and were under pressure to achieve Kennedy’s commitment to land before the end of the decade.

With SLS/Orion there is no such pressure. What is driving their lack of testing is a lack of money, caused by the project’s ungodly cost. They not only can’t afford to build multiple rockets to fly a variety of missions building up to the Moon, Congress hasn’t given them the money. Right now all they have allocated is enough to fly one unmanned mission in 2018, and this one manned flight in 2021 (which by the way is almost certainly going to be delayed until 2023).

The worst aspect of SLS/Orion is its stuntlike nature. They aren’t building anything that will have any permanence or allow for future colonization. It costs too much. Instead, SLS/Orion is designed to do one or two PR missions that will look good on some politician’s resume, but will do little to further the colonization of the solar system by the U.S.

Software issues threaten Orion/SLS schedule

8:36 am

Despite having more than a decade to develop the software for SLS and Orion, NASA now faces the possibility that the rocket’s first test flight in 2018 might be delayed because that software is not ready.

Specifically, a NASA advisory board has revealed that Orion’s flight software is behind schedule and might not be ready in time. This, combined with schedule problems for the capsule’s service module, being built by the European Space Agency, threatens the 2018 launch date.

NASA considers alternatives to Orion

6:33 pm

The competition heats up: Faced with long delays and an ungodly budget, NASA is now considering alternatives to replace the Orion capsule.

NASA has initiated a process that raises questions about the future of its Orion spacecraft. So far, this procedural effort has flown largely under the radar, because it came in the form of a subtle Request for Information (RFI) that nominally seeks to extend NASA’s contract to acquire future Orion vehicles after Exploration Mission-2, which likely will fly sometime between 2021 and 2023.

Nevertheless, three sources familiar with the RFI, who agreed to speak on the condition of anonymity, told Ars there is more to the request than a simple extension for Orion’s primary contractor, Lockheed Martin. Perhaps most radically, the RFI may even open the way for a competitor, such as Boeing or SpaceX, to substitute its own upgraded capsule for Orion in the mid-2020s.

The article also has this juicy quote:

The new RFI states that Lockheed will continue with development of Orion through a second uncrewed flight set for late 2018 and Exploration Mission-2, the first crewed mission, as early as 2021. However, once this “base vehicle” configuration is established, the RFI signals NASA’s intent to find a less expensive path forward. “This RFI serves as an examination of the market, which is an initial step in pursuing any of the available acquisition strategies, including the exercising of existing options,” the document states.

The end of SLS and Orion is beginning.

Orion faces more delays

10:00 pm

Faced with looming schedule problems for Europe’s effort to build the service module for the Orion capsule, NASA has created a working group to attack the problem.

The European Service Module (ESM) element of Orion has been classed as a major schedule driver for the program for some time. The Service Module for Orion was originally going to be an all-American system, under the control of Lockheed Martin. However, a deal back in 2012 resulted in an alliance with the European Space Agency (ESA) to utilize hardware associated with its Automated Transfer Vehicle (ATV).

The deal made sense. NASA’s goal of international collaboration is deemed to be an essential formula for spreading the costs and increasing the viability of NASA’s exploration goals, building on the success of the partnerships that built the International Space Station. Also, the ATV is proven technology, having already proved its worth via a string of successful resupply missions to the orbital outpost.

However, the challenge of combining the technology into what is essentially an American vehicle has resulted in schedule pressures.

Let me once again point out that Orion was first proposed by President George Bush in 2004. Its first official flight, with service module, is now scheduled for 2018. That means it took NASA 14 years to build and launch a unmanned single complete capsule, assuming they can get the service module built in time. That it took that long to build this is shameful. That there is even the slightest possibility that 14 years won’t be enough time to build the service module is downright disgusting, and is another illustration of the complete failure of the federal government.

Note that the previous unmanned Orion test flight in 2014 really doesn’t count. That capsule was a engineering test capsule, designed to test the capsule’s heat shield, even though NASA had already decided before the flight to abandon that heat shield design. In other words, it was a complete waste of money.

SLS schedule changes impending

9:52 am

NASA’s refurbishment plans for the mobile launcher and SLS launchpad suggest that the first manned flight of SLS is increasingly likely to be delayed from its present 2021 launch date.

The situation is complicated. The SLS configuration that will launch an unmanned capsule in December 2018 will use a Delta rocket upper stage, and will only have the capability of launching about 70 metric tons into low Earth orbit. After this one flight NASA wants to begin using SLS’s own upper stage, which it calls the Exploration Upper Stage and which will raise the rocket’s payload capacity to 105 metric tons. Because these changes will make SLS taller, however, they have to refurbish both the mobile launcher that brings the rocket to the launchpad as well as the launch tower used to fuel the rocket during countdown. These changes, now scheduled, will shut down the launchpad from January 2019 until the end of 2020.

The problem with doing this is that SLS’s second flight, presently scheduled in 2021, is supposed to be manned. To use the Exploration Upper Stage untested on this manned flight is something NASA doesn’t really want to do. Flying another unmanned flight to test that upper stage however will require NASA to delay the first manned flight again, probably to 2023.

Based on the article at the link above, those delays now seem almost certain. Because NASA is moving to refurbish the launchpad right after that first unmanned flight in December 2018, this means all later SLS launches will use the Exploration Upper Stage. Since Congress has also ordered NASA to fly its upcoming Europa orbiter mission on SLS, it seems to me that NASA is now quietly moving to add a second unmanned SLS test flight between the rocket’s first flight in 2018 and the first manned flight and will use it to launch the Europa orbiter some time in 2021. This will in turn delay the launch of that first manned flight, probably until 2023, a date that is presently listed in many NASA documents as the latest SLS’s first manned mission will fly.

If this is the case, it means that it will have literally taken NASA two decades to build and fly a single manned Orion capsule, beginning when George Bush ordered the construction of the Crew Exploration Vehicle in January 2004.

Does no one but me see something wrong here?

Charles Bolden poo-poos private space

12:33 pm

In remarks at a conference yesterday NASA administrator Charles Bolden expressed his distrust and lack of confidence in the ability of private companies to build large heavy lift rockets.

“If you talk about launch vehicles, we believe our responsibility to the nation is to take care of things that normal people cannot do, or don’t want to do, like large launch vehicles,” Bolden said. “I’m not a big fan of commercial investment in large launch vehicles just yet.”

…Despite the demonstrable efforts by both SpaceX and Blue Origin, Bolden nonetheless said that “normal people” cannot, or do not want to, develop large launch vehicles. What the administrator appears to be asserting here is that NASA is more special, or better, than those in the private sector when it comes to building rockets.

The article at the link notes the strangeness of Bolden’s remarks, especially since NASA itself has failed, despite repeated efforts, to build its own new rocket since the 1970s. The author also notes the high cost of SLS, though the numbers he cites — $13 billion to develop and build SLS — is actually about half the real cost, which will be about $25 billion to build two SLS rockets.

Bolden here illustrates the old way of doing things. He will be gone soon, however, and a new way will replace him, private, competitive, innovative, and fast moving, everything that NASA has not been in the past four decades.

The status of SLS for its first launch in 2018

9:49 am

Link here. The article gives an excellent and detailed overview of where construction of SLS presently sits, what the problems are that still remain, and what they have done to overcome them.

What struck me most however in reading the article was how long it takes them to do anything. For example, it appears they will assemble the rocket in the spring of 2018 for a December launch. In fact, the description of this assembly in this article partly explains to me why SLS will have the ungodly slow launch rate of at best once every two years.

In addition, the article describes how NASA has handled a number of engineering issues that have come up, and for each the approach seems to me to be more complicated than necessary. However, I am not an engineer and have never been part of this kind of work. Maybe everyone does it this way.

NASA finalizes more cubesat deals for first SLS launch

11:19 pm

Lockheed Martin and NASA have signed a deal to put a science cubesat on the first SLS rocket, planned for an unmanned launch of Orion in 2018.

The adapter ring that connects Orion to the rocket will include 13 bays for CubeSats, shoe-box sized payloads that until now haven’t been delivered in significant numbers into deep space. Each of those payload operators is working to finalize contracts with NASA for the ride into space, and on Monday, Lockheed Martin announced a few details of its 6U CubeSat, called SkyFire. Lockheed’s payload will capture high-quality images of the Moon. And in exchange for the ride into deep space, NASA will receive data from the mission.

“The CubeSat will look for specific lunar characteristics like solar illumination areas,” James Russell, Lockheed Martin SkyFire principal investigator, said in a news release. “We’ll be able to see new things with sensors that are less costly to make and send to space.”

This is without doubt a great opportunity for Lockheed Martin and others to test the use of a cubesat in interplanetary space. Whether it makes sense to use SLS to launch them is another matter entirely.

NASA delays asteroid redirect mission one year

8:48 am

NASA has decided to delay by one year the planned launch dates for both its unmanned and manned missions to an asteroid.

And why might you ask?

Mr. Gerstenmaier further stated that “We had trouble getting the funding together for this thing. So this slip of the one year that you see wasn’t caused by technical. It was really caused by budget availability. We just didn’t have the budget available to go do this.”

Also, the article notes that the launch rocket for the unmanned mission, now set for 2021, will be one of three possible rockets.

No elaboration was given as to what those “three rockets” are, though SLS, one of SpaceX’s Falcon family of rockets, and Atlas V are understood to be the prime contenders at this time.

The unmanned mission might happen (though I wouldn’t bet on it). As for the manned mission, there is a reason NASA has had trouble getting funding. SLS/Orion cost too much. Congress simply doesn’t want to spend that much for the actual missions. They will dole out a lot of cash for development (and the pork that goes with it), but even they can’t afford the gigantic budgets NASA needs to actually fly real missions.
