The federal government’s blank check

9:38 am

Three articles this morning about actions taken by Congress in connection with the budgets for NASA and NOAA illustrate the bankrupt nature of our federal government.

The first story describes how several legislators from the House Appropriations Committee have inserted amendments into their budget bill that will restore a $10 million NASA climate monitoring program that the Trump administration had shut down.

The second story describes how that same budget bill generously funds both NASA and NOAA at levels far above their own requests.

Contamination found in shuttle engines to be used by SLS

12:03 am

Now we know why the first launch is likely delayed: It appears that contamination has been found in the used and refurbished shuttle engines that the Space Launch System is using.

A “routine quality assurance inspection” of the core stage, he said, discovered contamination in tubing in the engine section of the core stage, which hosts the vehicle’s four RS-25 main engines and associated systems. That contamination turned out to be paraffin wax, which is used to keep the tubes from crimping while being manufactured but is supposed to be cleaned out before shipment.

“The prime contractor determined the vendor was not fully cleaning the tubes and it was leaving residue in the tubes,” McErlean said. “This was retained as a requirement in the prime contractor’s spec, but it was not properly carried out.” Boeing is the prime contractor for the SLS core stage, but he did not disclose the vendor who provided the contaminated tubing.

The contamination was initially found in a single tube, he said, but later checks found similar residue in other tubes. All the tubing in the core stage is now being inspected and cleaned, a process he said is not straightforward because of the “mass of tubing” in the engine section and also because cleaning is a “non-trivial process.”

Some obvious questions immediately arise:

1. These engines were previously flown on the space shuttles, numerous times. How did the paraffin wax, used “to keep the tubes from crimping while being manufactured,” remain in the tubes during all those shuttle flights?

2. Assuming the tubes were a new addition or replacement during the refurbishing process, it still seems astonishing that a subcontractor could be so lax. Did they really believe the wax did not need to be thoroughly cleaned?

3. While they have admitted that they will likely have to delay the launch because of issues with the core stage, why do they deny this contamination problem is the cause? More important, how much is it costing to fix? And how much time are they actually losing to fix it?

4. Finally, this is only one of many similar problems that we have seen with this entire project. Boeing and NASA have gotten so far about $40 billion to build this rocket, and have been working on it since 2006, more than a dozen years ago. Furthermore, they supposedly are building it using shuttle equipment in a Saturn rocket-type design in order to save money and time. Instead, they have wasted billions and taken more than three times longer than it took us to win World War II to get to a point where the program still has not flown.

Does anyone really believe this project is anything but a huge boondoggle? And if so, can they please tell me how it will be possible for the United States to really explore the heavens with a project run this incompetently?

Another delay for SLS

8:36 am

This really isn’t news: Work on the core stage for the first SLS rocket launch appears to face another three month delay, threatening the scheduled June 2020 launch date.

The article outlines in great detail the work being done on the SLS core stage, and where the delays might be coming from, while also being vague about what exactly is causing the delay.

It is unknown if the additional time for completion of final assembly of the whole rocket stage is based on the engine section, the other four elements, or continuing refinement of forward work. Most of the hardware and systems that will fly on EM-1 are being built for the first time and the procedures to connect the five pieces of the Core Stage together will also be attempted for the first time.

Of the five elements, the most recent news had the Forward Skirt near completion of its individual work by the end of the month. Work to cover the liquid oxygen tank with its Thermal Protection System (TPS) foam was in final phases, with the liquid hydrogen tank to follow behind it. The engine section and intertank elements continue to be outfitted with propellant lines, pressure tanks, avionics boxes, wiring, and other equipment.

Once complete, the elements will be assembled vertically in two stacks before a horizontal join of the halves of the rocket kicks off final assembly.

In fact, reading the article’s detailed description of the testing and assembly of SLS’s core stage struck me as incredibly slow-paced, so slow paced that it actually filled me with a sense of ennui. In the time they seem to need to only do an equipment review, SpaceX appears to have upgraded and flown a new version of its Falcon 9 first stage, while also redesigning a new core stage for its Falcon Heavy.

The aging data relay spacecraft orbiting Mars

9:40 am

By the 2020s, NASA and other space agencies sending landers and rovers to Mars will be faced with a data-relay crisis, as the orbiters they presently use to provide communications with the Martian surface are aging, and no replacements are presently planned.

The venerable Mars Global Surveyor (MGS) and Mars Odyssey spacecraft were the first to employ data relay capabilities in the modern era of Mars exploration. They operated as relays for the twin Mars Exploration Rover missions until the arrival of the Mars Reconnaissance Orbiter (MRO) in 2006.

MGS entered into a safe mode in November 2006 and NASA later declared the mission over in January 2007 after the space agency failed to reestablish contact with the aging orbiter. The 12-year-old MRO and 17-year-old Odyssey have served as the primary data relays for Mars surface missions since.

More important, funding for a dedicated communications satellite called NEMO, planned for launch in 2022, has disappeared.

However, funding for NeMO has been largely phased out in favor of directing limited funds towards the development of the Mars Sample Return mission. Mars Sample Return has the primary objective of fetching samples that scientists plan to collect and cache using the Mars 2020 rover currently under development. The current Planetary Science Decadal Survey has listed the flagship sample return mission as the primary objective for NASA’s Mars program in the 2020s, along with requisite funding. The existing fleet of orbiting spacecraft at Mars, while aging, are in generally good health meaning the postponement of a new orbiter will require careful management of existing orbital assets into the next decade.

One of the reasons there is no funding for NEMO is that NASA has had to steal money from its planetary program to fund the cost overruns on the James Webb Telescope. Though this was never admitted publicly, the cuts that the Obama administration imposed on the planetary program were partly to pay for Webb. Thus, not only has that telescope killed almost all of NASA’s entire astrophysics program, it has damaged the planetary program as well.

Russian to fly on Orion?

9:12 am

In negotiations between NASA and Roscosmos on their hoped-for partnership to build the Lunar Orbital Platform-Gateway (LOP-G), it has been proposed that when SLS carries Orion and the platform’s Russian airlock to lunar orbit a Russian will go as well.

“Within the framework of talks, draft plans of future manned missions to the lunar stations have been made. Among other issues, the possibility to send one Russian cosmonaut as part of the crew of the Orion spacecraft that will drag the Russian airlock module to the moon is on the agenda. The Russian cosmonaut will have to ensure the integration of the module with the station,” the source said.

A source in Russia’s Rocket and Space Corporation Energia (RSC Energia) that would produce the module confirmed this information to Sputnik, saying that four manned missions were expected to be sent to the station and the Russian cosmonaut should accompany the Russian-made module during its transportation to the Earth satellite.

This all sounds so wonderful. Too bad it is so unconnected with reality. Congress has yet to provide any funds for LOP-G. At the moment, SLS/Orion is only funded through its first manned mission.

At the same time, I am getting the feeling that both NASA and Congress expect SLS/Orion’s $4 billion-plus annual budget that it has gotten since the program started in the late 2000s will simply continue, giving them the money to build this Potemkin Village in orbit around the Moon while funding the Russian contributions.

That’s what happened with ISS. The U.S. footed most of the bills for the Russian portion of ISS, and the Russians are now hoping we will do the same for LOP-G. Sadly, I also expect our corrupt Congress will go along, focused as they are in only distributing pork to local districts while encouraging a global international village having nothing to do with American interests. They see LOP-G not as exploring space, but as a jobs program, both here in the U.S. and in Russia.

And a jobs program is exactly what it is. Just like it will take SLS/Orion almost two decades to complete its first manned launch, LOP-G will likely not get anything built in orbit around the Moon for more than a decade. Don’t expect anything substantial assembled in lunar orbit before the mid-2030s, at the earliest.

More problems uncovered during testing of the James Webb Space Telescope

8:42 am

During ground tests of the James Webb Space Telescope engineers have discovered an additional quite astonishing problem that will certainly delay the project again.

In a presentation at a meeting of the National Academies’ Space Studies Board here May 3, Greg Robinson, the JWST program director at NASA Headquarters, said some “screws and washers” appear to have come off the spacecraft during recent environmental testing at a Northrop Grumman facility in Southern California.

Technicians found the items after the spacecraft element of JWST, which includes the bus and sunshield but not its optics and instruments, was moved last weekend from one chamber for acoustics tests to another to prepare for vibration testing.

“Right now we believe that all of this hardware — we’re talking screws and washers here — come from the sunshield cover,” he said. “We’re looking at what this really means and what is the recovery plan.” The problem, he said, was only a couple of days old, and he had few additional details about the problem. “It’s not terrible news, but it’s not good news, either,” he said. [emphasis mine]

The absurd spin expressed by the program director above is garbage. This is unbelievable and entirely unacceptable. On spacecraft, especially those that are not planned for in-space maintenance like Webb, screws are routinely sealed with some form of glue so that they will not unscrew themselves during the vibrations of launch. This is standard space engineering and has been for more than a half century.

That some screws came off Webb during testing suggests a quality control problem at Northrop Grumman that is beyond comprehension.

GAO predicts more delays and cost increases in NASA’s big projects

10:30 am

The Government Accountability Office is predicting more delays and cost increases for most of NASA’s big projects in its tenth annual report.

The cost and schedule performance” of NASA’s major projects “has deteriorated, but the extent of cost deterioration is unknown” because NASA does not have a cost estimate for Orion. Orion is “one of the largest projects in the portfolio” and NASA “expects cost growth.”

As for schedule, “the average launch delay for the portfolio was 12 months, the highest delay GAO has reported in its 10 years” of making these assessments. GAO said the 12-month average delay is up from 7 months in last year’s assessment.

Further, NASA faces the risk of more cost and schedule growth because of “new, large, complex projects that will enter the portfolio and expensive projects remaining the portfolio longer than expected.” Europa Clipper, the Wide-Field Infrared Survey Telescope (WFIRST), the Lunar Orbital Platform-Gateway, and Europa Lander are cited as examples of those future large, complex projects. GAO did give NASA credit for putting processes in place to control the costs of Europa Clipper and WFIRST.

GAO identified nine existing projects as the biggest contributors to the poor cost and schedule performance: SLS, Exploration Ground Systems (EGS), the Space Network Ground Segment Sustainment (SGSS) cited in the 2017 report, Mars 2020, the James Webb Space Telescope (JWST), ICESat-2, NISAR, ICON, and GRACE-FO (GRACE-Follow On).

Orion has cost already cost the taxpayer about $15 billion, all of which will only buy the taxpayer three capsules (two unmanned test flights and a single manned flight). And yet they don’t have enough money yet, and NASA can’t provide a total cost estimate? To me, this appears to be outright theft. Building three capsules simply shouldn’t cost that much. (Note: the report claims Orion has cost about $6.6 billion. My number above comes from actual appropriations by Congress specifically for Orion. I think my number is a far more accurate reflection of the project’s true cost.)

Though the report expresses concerns about schedule delays in the commercial crew program, it is with the NASA-run projects that the report finds the worst cost overruns and delays. All of the usual suspects above come in for criticism: Webb, WFIRST, SLS (and its associated ground facilities), Orion, LOP-G.

I will make a prediction: All these NASA projects will be cited for further cost overruns and further delays in next year’s GAO report. By that time, we shall have also seen the first test flights of the commercial crew capsules by Boeing and SpaceX.

NASA tests new small fission power plant for future space missions

10:08 am

NASA has successfully completed a full test of a new small fission power plant that it hopes to use in future space missions.

The prototype power system uses a solid, cast uranium-235 reactor core, about the size of a paper towel roll. Passive sodium heat pipes transfer reactor heat to high-efficiency Stirling engines, which convert the heat to electricity.

According to David Poston, the chief reactor designer at NNSA’s Los Alamos National Laboratory, the purpose of the recent experiment in Nevada was two-fold: to demonstrate that the system can create electricity with fission power, and to show the system is stable and safe no matter what environment it encounters. “We threw everything we could at this reactor, in terms of nominal and off-normal operating scenarios and KRUSTY passed with flying colors,” said Poston.

The Kilopower team conducted the experiment in four phases. The first two phases, conducted without power, confirmed that each component of the system behaved as expected. During the third phase, the team increased power to heat the core incrementally before moving on to the final phase. The experiment culminated with a 28-hour, full-power test that simulated a mission, including reactor startup, ramp to full power, steady operation and shutdown.

Throughout the experiment, the team simulated power reduction, failed engines and failed heat pipes, showing that the system could continue to operate and successfully handle multiple failures.

This power plant appears similar in concept to the fission RTG nuclear fuel systems that have been used routinely for decades on unmanned planetary probes such as the two Voyager spacecraft, New Horizons, and on Curiosity. This new system however provides significantly more power, as much as ten kilowatts compared to the approximate two hundred watts provided by RTGs.

Such a system will be essential for future bases on both Mars and the Moon, where solar power is not the best option. I should also add that such a system might possibly have applications here on Earth. Developed properly, it could provide a practical power source for out-of-the-way locations not on the grid. If made cheap enough, it might also provide electrical customers a cheaper and competitive alternative that will allow them to remove themselves from the grid entirely.

Bridenstine confirmed as NASA administrator

2:32 pm

After an eight month delay, caused partly by the refusal of any Democrats to vote for a Trump nominee, Congressman Jim Bridenstine (R-Oklahoma) was today confirmed as NASA’s administrator.

The vote passed 50-49, and only finally occurred because Senator Marco Rubio (R-Florida) decided to stop opposing Bridenstine.

I don’t think this nomination will matter much. The people who are really in charge of the U.S. space effort don’t work for NASA, and in fact are not even in the government. They also have enough financial power that they probably can force NASA to do what they want, over the long run. Bridenstine will I think carry water for them.

Sierra Nevada opens all rockets to launching Dream Chaser

9:33 am

In a status update for its Dream Chaser reusable mini-shuttle cargo ship to ISS, Sierra Nevada officials also revealed that they are considering a wide range of launch companies for future launches.

SNC announced a contract with ULA in July 2017 that covered two Dream Chaser launches, in 2020 and 2021. Both would use the Atlas 5 552, the largest version of the Atlas 5 with a five-meter payload fairing, five solid rocket boosters and a dual-engine Centaur upper stage.

However, Sirangelo said the company was looking at other options for launching the second and later Dream Chaser ISS cargo missions. “It’s a quite interesting time in the launch business, where we see all the major launch companies coming out with a new launch system,” he said. “We are looking at all of the launch systems.” Sirangelo said later that the company issued a request for proposals for multiple Dream Chaser launches. “We’ll probably be making a decision by the end of this year,” he said. “We’re gotten tremendous response for it.” He declined to discuss specific vehicles under consideration but said SNC received “really great response from all the major providers.”

Their willingness to open up the launch bidding is merely a recognition that they can save money by encouraging competition for their business. The vehicle itself has not yet completed its design review, though they hope to begin its assembly within a month, with a planned launch date in late 2020.

The company was awarded its cargo contract in January 2016, more than two years ago. It seems to me that it has taken far too long to get to this point. I wonder if NASA has thrown up roadblocks, as it has with SpaceX.

FCC upset FCC not included in National Space Council

9:32 am

Turf war! The FCC commissioner today questioned the omission of an FCC representative on Trump’s reborn National Space Council.

Commissioner Jessica Rosenworcel said April 17 that the Federal Communications Commission “needs to coordinate more closely with other federal authorities” as it navigates through new space activities. “Right now the National Space Council is considering policy changes to help promote the growth of the commercial space industry,” she said. “Their efforts encompass everything from streamlining licenses to reforming export controls, protecting airwaves, to facilitating space activities … the FCC should have a seat at the table. It’s a glaring omission that this agency does not, because through our oversight of the airwaves and licensing of satellite services, we have an important role ensuring the viability of space for future generations.”

Rosenworcel noted that the National Space Council as revived by the Trump administration last year has a distinguished list of leaders, including the head of NASA, the secretaries of defense, transportation and homeland security, and others, calling it “an impressive list.” But “cutting the FCC out of this discussion is an unseemly mistake, and one that deserves a fix,” she said.

To translate: The FCC wants to keep its regulatory power over space operations, and by excluding them from the council Trump is threatening that power. This is unacceptable!

If the Trump administration is truly serious about streamlining the space regulatory bureaucracy, we should hear more complaints like this in the coming months, from the FAA, NASA, the State Department, and other agencies. Normally such government streamlining efforts only make things worse, because all the threatened government agencies chime in with complaints like this. The result is that nothing gets streamlined. Instead, the effort merely adds another layer of bureaucracy, as illustrated by my previous post.

NASA might scale down the first manned SLS flight

10:10 pm

In order to meet its present schedule and budget, NASA is considering scaling down its first manned SLS flight in 2023 by using the same smaller version of SLS that will fly the first unmanned test flight in 2020.

The SLS has been in development for the last decade, and when complete, it will be NASA’s main rocket for taking astronauts to the Moon and Mars. NASA has long planned to debut the SLS with two crucial test missions. The first flight, called EM-1, will be uncrewed, and it will send the smallest planned version of the rocket on a three-week long trip around the Moon. Three years later, NASA plans to launch a bigger, more powerful version of the rocket around the Moon with a two-person crew — a mission called EM-2.

But now, NASA may delay that rocket upgrade and fly the same small version of the SLS for the crewed flight instead. If that happens, NASA would need to come up with a different type of mission for the crew to do since they won’t be riding on the more powerful version of the vehicle. “If EM-2 flies that way, we would have to change the mission profile because we can’t do what we could do if we had the [larger SLS],” Robert Lightfoot, NASA’s acting administrator, said during a Congressional hearing yesterday.

NASA clarified that astronauts would still fly around the Moon on the second flight. However, the rocket would not be able to carry extra science payloads as NASA had originally planned. “The primary objective for EM-2 is to demonstrate critical functions with crew aboard, including mission planning, system performance, crew interfaces, and navigation and guidance in deep space, which can be accomplished on a Block 1 SLS,” a NASA spokesperson said in a statement to The Verge.

The problem here really is that Congress keeps throwing money at this boondoggle. It will fly, but it will never be able to make the exploration and colonization of the solar system possible. It is simply too expensive and has a far too slow launch rate. Instead, it will allow for NASA to do stunts in space, while elected officials can preen and prance about, bragging about the jobs they brought to their districts.

And the nation’s debt will grow, and grow, and grow.

I hold to my prediction that private companies will bypass SLS in the 2020s, doing far more for far less. The differences between them will become downright embarrassing to SLS and Congress.

Status update on Mars Reconnaissance Orbiter

9:25 am

Link here. The story is focused on the decision by NASA to hold off launching a replacement for MRO and instead keep it operating for another decade. In telling this story, however, the article also provides us a detail look at the spacecraft’s present condition.

[A]ging batteries and gyroscopes, used to store electricity and aid navigation, will have to be carefully watched in the coming years to keep the mission going. “We found that they weren’t charging at full capacity,” Tamppari said of the batteries. MRO charges its batteries through its solar arrays while in sunlight. During night passes over Mars, the orbiter draws electricity from its batteries for about 40 minutes during each two-hour lap around the planet. The spacecraft now charges its batteries higher than before, NASA said, and engineers sent up commands for MRO to reduce the draw on the batteries while in shadow.

MRO’s two inertial measurement units are also showing signs of their age. Each redundant unit contains three gyroscopes and three accelerometers, feeding data about the spacecraft’s orientation to on-board computers. One measurement unit likely in the final months of its useful lifetime, Tamppari said, and the other is showing signs of degradation.

Ground controllers found a work-around by implementing an “all-stellar” navigation mode on MRO in March. The new technique allows the orbiter to sense the positions of the stars to determine which way it is pointing. “In all-stellar mode, we can do normal science and normal relay,” said Dan Johnston, MRO project manager at JPL, in a statement released in February. “The inertial measurement unit powers back on only when it’s needed, such as during safe mode, orbital trim maneuvers, or communications coverage during critical events around a Mars landing.”

There’s more at the link. Since MRO is also used as the main communications relay satellite between the Martian ground-based probes and the Earth, the story also outlines the communications capabilities of all spacecraft presently orbiting Mars. All told, it seems that if MRO fails the research on the surface will be significantly impacted, even if the rovers and landers are all still working.

NASA expands first manned Starliner mission

8:35 am

NASA has modified its contract with Boeing to allow its first manned Starliner test mission to add an astronaut and extend the mission’s length so that it more resembles an operational flight to ISS.

NASA is considering adding a third crew member to the Starliner’s “Crew Flight Test” and could extend its trip to the International Space Station from two weeks up to six months, the length of a typical ISS expedition. The potential changes, outlined in a contract modification with Boeing, could help NASA maintain its presence on the International Space Station through 2019 and beyond.

NASA’s last purchased ride aboard a Russian Soyuz spacecraft, upon which the U.S. has relied for access to the ISS since the shuttle’s retirement in 2011, is scheduled to launch in the fall of 2019.
Boeing’s new Starliner spacesuit features lightweight fabric, slim gloves and sneaker-like boots. But Boeing’s Starliner and SpaceX’s Crew Dragon may not be certified to fly four-person crews until after that. “This contract modification provides NASA with additional schedule margin if needed,” said Bill Gerstenmaier, head of human spaceflight operations at NASA headquarters in Washington. “We appreciate Boeing’s willingness to evolve its flight to ensure we have continued access to space for our astronauts.”

Doing this makes some sense, but I wonder why NASA chose to do it with Boeing’s Starliner instead of SpaceX’s Dragon. Starliner has never flown in any form, while the manned Dragon is based on SpaceX’s well tested design.

I suspect NASA will soon modify its SpaceX contract as well. It makes sense. Once you put humans on board, you might as well give yourself the option to do a full mission.

NASA’s horrible management of SLS

8:25 am

In this article from NASASpaceflight.com describing a recent status update from NASA of its SLS/Orion program (which remains years behind schedule and might see further delays) was the following quote, revealing much about NASA’s incompetence and corruption in building this boondoggle:

In contrast to the more centralized organization structure for the cancelled Constellation program, [SLS’s] three major programs [ground systems, Orion, and SLS] are managed independently: Exploration Ground Systems (EGS) based at KSC, Orion based at the Johnson Space Center (JSC) in Houston, Texas, and SLS based at the Marshall Space Flight Center (MSFC) in Huntsville, Alabama.

Each of the programs has resources to integrate with its other two partners, but ESD [Exploration Systems Development at NASA headquarters in DC] provides the overall coordination between all three. During Constellation, the equivalent organizations were projects directly managed by that now-cancelled program. [emphasis mine]

In other words, when Obama unilaterally cancelled Constellation (something he really didn’t have the power to do) and Congress micromanaged its reinstatement (creating SLS/Orion), the Obama administration and NASA abandoned a sensible management structure and allowed SLS/Orion to be a three-headed monster, difficult to coordinate and certain to go over-budget and fall behind schedule.

With this operational structure, even if SLS eventually flies successfully, it will be impossible for it to operate efficiently. Expect every one of its future efforts to always go over budget and to fall behind schedule.

Further launch delays for Russia’s next ISS module & space telescope

9:18 am

The race to be last! Russia today announced that the launch of both its next ISS module as well as a new space telescope will be delayed until 2019.

The ISS module, Nauka, is years behind schedule, and is presently being cleaned of contamination in its fuel system that was found several years ago.

“Repairs of the MLM Nauka are taking longer than expected, and the deadlines are yet unclear. This means it will not be brought to Baikonur any time soon, and the launch will be postponed until 2019,” the source said.

It was reported earlier that the mission would be delayed for six months. “The delivery of the MLM Nauka to the Baikonur cosmodrome has been moved from September to late 2018. Hence, the module’s launch to the ISS has been provisionally delayed for another six months,” the source said. The launch was scheduled for September 2018 with the possible alternative date in March 2019.

The article also notes delays for Spekr-RG high-energy space telescope until 2019. The article might also describe delays for another satellite, though the writing is unclear.

Nauka was first built in the 1990s as a backup for ISS’s first module. In the early 2000s Russia decided to reconfigure it and fly it to ISS, with its launch scheduled for 2007. This means its launch is now going to be twelve years behind schedule.

It sure does appear that Russia’s Roscosmos is competing with NASA to see which government agency can delay its missions the longest. In fact, for fun, let’s put together the standings!

  • Nauka: 12 years behind schedule (originally scheduled for 2007, now 2019)
  • James Webb Space Telescope: 9 years behind schedule (originally scheduled for 2011, now 2020)
  • SLS/Orion: 8 years behind schedule (originally scheduled for 2015, now 2023)

Stay tuned. This race to the bottom is far from over. NASA could still win, especially because it has more than one project in the running.

First commercial crew flights still set for 2018 with chance of delay

9:03 am

NASA’s manager of the commercial crew program provided an update to the agency’s advisory board on Monday, noting that both SpaceX and Boeing are making good progress to their scheduled first flights late this year.

The bottom line however is that there is a good chance the flights will slip into 2019, though based on the update it appears to me that the flights will not slip that much beyond that.

Webb telescope delayed again to 2020

10:34 am

NASA has announced that it is once again delaying the launch of the James Webb Space Telescope, from 2019 to 2020.

The observatory was supposed to fly this year. But last fall, NASA bumped the launch to 2019. NASA announced the latest delay on Tuesday. “We have one shot to get this right before going into space,” said Thomas Zurbuchen, NASA’s associate administrator of science. He said some mistakes were made while preparing the telescope, and NASA underestimated the scale of the job. [emphasis mine]

None of this is a surprise. Webb is more pork than science. It was originally budgeted at $1 billion, with a planned launch in 2011. It will now cost more than $9 billion, and be delayed almost a decade. Since the project began in the early 2000s, by the time it launches it will have been in development for almost two decades, which is almost a lifetime career for some people.

And note, the article includes the lie that Webb is “a successor to the Hubble Space Telescope.” It is not. Hubble is an optical telescope. Webb will only look in the infrared. These are very different things.

NASA chief argues against purchasing Falcon Heavy over SLS

8:55 am

When asked at a meeting of a NASA advisory council meeting why NASA doesn’t buy a lot of Falcon Heavies instead of building a few SLS rockets, NASA chief of human spaceflight Bill Gerstenmaier argued that only the SLS could launch the large payloads NASA requires to establish its Lunar Orbiting Platform-Gateway (LOP-G).

Gerstenmaier then said NASA’s exploration program will require the unique capabilities of the SLS rocket. “I think it’s still going to be large-volume, monolithic pieces that are going to require an SLS kind of capability to get them out into space,” he said. “Then for routine servicing and bringing cargo, maybe bringing smaller crew vehicles other than Orion, then Falcon Heavy can play a role. What’s been talked about by [Jeff] Bezos can play a role. What United Launch Alliance has talked about can play a role.”

The problem with this argument is that the “large-volume, monolithic pieces” Gerstenmaier proposes don’t exist yet, either in design or in budget. NASA could very easily design LOP-G’s pieces to fit on Falcon Heavy, and then use it. Instead, they are purposely creating a situation where SLS is required, rather than going with the most cost effective solution.

Unless someone in power, such as a president, puts his foot down and demands NASA do this intelligently, I expect NASA to accomplish nothing significant in manned space in the next decade. That does not mean Americans will be trapped on Earth, only that NASA will not be the way they will get off the planet. And unfortunately, based on the most recent budget passed by Congress and signed by Trump, I do not expect this president to do anything to change things. Right now, NASA is being run by the big contractors (Boeing and Lockheed Martin) that need SLS and Orion, and thus NASA is going to give them a lot of money to build things that we can’t afford and can do nothing to put Americans in space.

Congress pumps pork money to NASA in omnibus budget

7:45 am

The omnibus budget that Congress plans to pass this week for 2018 gives NASA $20.7 billion, significantly more than requested and funding almost every pork project Congress could conceive of, including a second mobile launcher for SLS.

The budget gives SLS and Orion more than $3 billion, funds all the Earth science and education projects the Trump administration wished to cut, as well as WFIRST, which the Trump administration wants to cancel because of cost overruns. In general, the NASA budget is a microcosm of the entire spending bill, which does nothing to cut any program anywhere, including Obamacare and a number of liberal programs that the Republicans have repeatedly promised to shut down, until they are in a position to do so. Then they act like leftist Democrats and fund everything.

This is posted between Tucson and Phoenix. I am heading up to the Grand Canyon for a four day cave expedition, which is why I can’t do a more thorough analysis. This really isn’t necessary however, as it is very clear that the Republican leadership in Congress are continuing their corrupt passion for spending money that does not exist. And they wonder why they may lose seats in 2018.

NASA’s interim administrator to retire in April

11:00 pm

NASA’s interim administrator, Robert Lightfoot, has announced that he plans to retire in April.

Lightfoot’s retirement leaves NASA without any leadership, as the Senate has shown no interest in confirming Trump’s candidate for the position, Congressmen Jim Bridenstine (R-Oklahoma).

All 49 Democrats in the Senate are expected to vote against to Bridenstine’s confirmation, and Sen. Marco Rubio (R-Florida) is also reportedly also opposed, Space News reported. Sen. John McCain (R-Arizona) is not in Washington as he undergoes treatment for cancer, leaving Bridenstine short of the 50 votes needed for confirmation.

Bridenstine is not a perfect choice, and I have reservations about his commitment to commercial space, but the reasons for the Democratic opposition is, as far as I can tell, the same as all their other opposition to every other Trump or Republican proposal: pure spite. “We hate it because of YOU!”

The lack of a politically appointed administrator at NASA however is not necessarily a bad thing, considering that the important stuff happening right now is not at NASA but in the private sector. Having NASA adrift for awhile might actually work to weaken NASA’s pork projects, SLS and Orion, that are in direct competition with private space.

The ever-receding Space Launch System

10:20 am

Today a story at Space News reveals that NASA has decided to forgo construction of a second mobile launcher for its Space Launch System (SLS). Instead, they will modify the one they have.

The mobile launch platform, originally built for the Constellation Program and currently being modified to support the SLS, will be used for one launch of the initial Block 1 version of the SLS, designated Exploration Mission (EM) 1. That platform will then have to be modified to accommodate the taller Block 1B version that will be used on second and subsequent SLS missions.

Agency officials said late last year they were considering starting work on a second mobile launch platform designed from the beginning to accommodate the Block 1B version of the SLS. They argued that doing so could shorten the gap of at least 33 months between the first and second SLS missions caused in part by the modification work to the existing platform.

The first mobile launcher was built and modified for an estimated $300 to $500 million. NASA obviously has decided that the politics of building a second won’t fly. The cost is too great, as would be the political embarrassment of admitting they spent about a half a billion for a launcher they will only use once. (That this mobile launcher is leaning we will leave aside for the moment.)

What this does however is push back the first manned SLS/Orion launch. At present, the first unmanned mission is likely to go in June 2020 (though don’t be surprised if that date sees further delays). If it takes 33 months after that launch to reconfigure the launcher for the first manned mission, that manned mission cannot occur any sooner than April 2023. That second launch however is planned to be the first to use SLS’s new upper stage. To put humans on it untested seems foolish, doesn’t it? NASA is going to have to fly an extra mission to test that upper stage, which is going to add further delays to the schedule.

In November I predicted that the first manned SLS/Orion mission would not happen before 2025. At the time it was assumed that the second flight of SLS would have to launch the unmanned Europa Clipper mission, in order to test that upper stage. Now however it appears that the Trump administration wants to shift Europa Clipper to a commercial launch vehicle, probably Falcon Heavy.

This means that either astronauts will be flying on an untested SLS upper stage, or NASA will have to add a test launch in April 2023, followed some time thereafter by that manned mission. Since NASA does not at present have a budget for a third mission, I am not sure what is going to happen here.

What I do know is that SLS is certain to get delayed again. By 2025 we will have paid close to $50 billion for SLS and Orion, and the best we can hope for is a single manned mission. And that one mission will have taken 21 years to go from concept to launch.

This is not how you explore the solar system. With a schedule like this, all SLS and Orion are doing is distributing pork to congressional districts and to the big space companies (Boeing and Lockheed Martin) that are building both. Establishing the United States as a viable space-faring nation is the last thing these players have in mind.

Mars Reconnaissance Orbiter comes out of safe mode

7:28 am

On February 23 the Mars Reconnaissance Orbiter (MRO) engineering team was able to bring the spacecraft out of safe mode, after a low battery voltage reading caused it to shut down.

Mission team members brought MRO out of safe mode on Friday (Feb. 23), NASA officials said. The orbiter seems to be in good health overall; the battery voltage is back to normal, MRO is communicating with Earth, and temperatures and power levels are stable, agency officials said.

But MRO’s handlers haven’t put the orbiter back to work yet. “We’re in the diagnostic stage, to better understand the behavior of the batteries and ways to give ourselves more options for managing them in the future,” MRO project manager Dan Johnston, of NASA’s Jet Propulsion Laboratory in Pasadena, California, said in a statement. “We will restore MRO’s service as a relay for other missions as soon as we can do so with confidence in spacecraft safety — likely in about one week. After that, we will resume science observations.”

Overall this sounds like very good news.

Webb faces more delays, cost overruns

7:23 am

A new GAO report released yesterday says that the James Webb Space Telescope faces further delays and cost overruns.

This is par for the course. Webb has become an incredible boondoggle. I hope it eventually gets launched and works, but its gigantic cost, $8 to $9 billion (compared to an original $1 billion budget), and delayed schedule suggests that this was not the right way for NASA or the astronomical community to build its space telescopes. Further, this quote from the story suggests something fundamentally wrong:

The GAO report also noted that, during the sunshield deployment exercises, Northrop discovered several tears in the material which it attributed to “workmanship error.” Those tears can be repaired but may consume more schedule reserve.

Is this thing really going to work? I really hope so, but have been increasingly doubtful as the delays and problems have piled up.

Meanwhile, NASA and the astronomical community is still pushing to get funding for its next “Webb,” the Wide-Field Infrared Survey Telescope (WFIRST). This project, similar in scope as Webb, is hardly off the ground and already has budget overrun issues. The Trump administration recommended cancelling in its budget proposal earlier this month, but I would be surprised if that recommendation goes through, considering the pork this new project represents.

The first SLS mobile launcher is leaning

8:49 am

Though NASA says it is not a problem, they have now revealed that the very expensive mobile launcher to be used for the first unmanned SLS launch in 2019, is leaning slightly.

The notes spoke of engineers being concerned about a lean towards the North – which would be towards the rocket when mated – with the angle of the leaning claimed to be seen as increasing when the Vertical Stabilizer porch was installed. It was also claimed the ML Tower is twisting and this issue increased when the porch was installed. This was cited as the reason additional arm installations onto the Tower were placed on hold, until the leaning-twisting issue is understood. Next in line for installation are the ICPS (Interim Cryogenic Propulsion Stage) Umbilical Arm, the Crew Access Arm and the two Vehicle Stabilizer Arms.

NASASpaceFlight.com’s Philip Sloss took the concerns to NASA to ask for clarifications. NASA responded, saying “the ML leaning/bending was not the cause of the delay in the install of the Crew access arm. These are unrelated.” However, they did expand on the specific issue, mainly to note it is understood and does not currently require any additional mitigation or modification to the ML.

“NASA’s mobile launcher is structurally sound, built to specifications, and does not require a design change or modifications. As expected, the mobile launcher is not perfectly still,” a NASA spokesperson added.

Note that this mobile launcher is not compatible with the second SLS launch, which would be the first manned flight in 2023. NASA will either have to modify it significantly at great costs, or build another, discarding this launcher after only one use.

NASA approves 2020 launch window for first Dream Chaser flight

8:32 am

Capitalism in space: Sierra Nevada has gotten the okay from NASA to aim for a 2020 launch window for the first flight of its reusable Dream Chaser mini-shuttle.

SNC announced Feb. 7 that it had received “authority to proceed” on that mission using the company’s Dream Chaser vehicle. The mission will launch on a United Launch Alliance Atlas 5 rocket in late 2020. The mission is the first of six in the company’s Commercial Resupply Services (CRS) 2 contract it won in 2016 to transport cargo to and from the ISS. SNC received a CRS-2 contract along with current CRS providers Orbital ATK and SpaceX.

“While we won the contract a couple of years ago, the contract still needed to be validated by a task order,” said Mark Sirangelo, executive vice president of SNC’s Space Systems business area, in a Feb. 7 speech at the Federal Aviation Administration’s Commercial Space Transportation Conference here. That order, he said, is the “biggest step” to date on the program. That flight will be a “full scale, fully operational mission,” he said, even though it will represent the first orbital flight of the Dream Chaser. Orbital ATK and SpaceX, who developed their Cygnus and Dragon spacecraft, respectively, under earlier NASA Space Act Agreements, flew demonstration missions before starting their operational CRS cargo flights.

Do not be surprised if this flight does not launch on schedule. I fully expect that development will push it back into 2021, a delay that would not be unreasonable.

Lockheed Martin starts assembling first manned Orion capsule

10:38 am

My heart be still! Thirteen years after winning its contract to built the manned Orion capsule, Lockheed Martin proudly announced this week that it has finally begun building the first capsule that will carry humans.

I should add that this first manned flight is not scheduled to happen for another five years. Moreover, they have so far spent at least $14 billion on this capsule, and will likely spend another five billion by the time it finally launches. That’s 18 years and $19 billion, for a single manned mission. Seems somewhat shameful to me.

The article is filled with much of the dishonest hyperbole that has surrounded the Orion capsule from the start:

  • “NASA’s first of a new generation of manned deep space exploration craft”
  • “Orion will be a major step in the American program to establish a Deep Space Gateway station, return to the Moon, and eventually make a manned landing on Mars”
  • “Orion has tremendous momentum.”
  • “This is not only the most advanced spacecraft ever built, its production will be more efficient than any previous capsule.”

What Orion really is is a lie. It is nothing more than the ascent/descent capsule for the as-yet still undesigned, unfunded, and unbuilt interplanetary spaceship that will be needed for any real deep missions. It is also a boondoggle of the worst sort, providing pork for congressional districts while accomplishing nothing.

Lockheed Martin is lying in its press release here, and it is shameful that any journalist who knows anything about space should buy into those lies.

New Zimmerman op-ed: NASA’s safety bureaucracy sabotaging manned space

9:50 pm

The website American Greatness has now published a new op-ed I have written that describes how the bureaucracy at NASA is acting to sabotage commercial space, even as it ignores far more significant safety issues with SLS and Orion.

I was prompted to write the op-ed after reading the reports in the past few weeks by NASA’s safety panel and the GAO, both of which clearly favored NASA’s bloated projects.

What both reports actually demonstrate is that the bureaucrats in Washington have very little interest in safety, but instead are more focused on putting their thumbs on the scale in order specifically to harm these private efforts—especially SpaceX’s. One report in particular, by NASA’s Aerospace Safety Advisory Panel (ASAP), was especially hostile to these private efforts, even as it remained completely unconcerned about similar but far worse safety issues that exist with NASA’s government-built and competing SLS and Orion programs.

Both reports also illustrated starkly the complete lack of understanding that the Washington community has for the nature of exploration, the very task that NASA was founded to spearhead. The result is a bureaucratic culture that makes the manned exploration of space by the United States practically impossible.

If things do not change, expect this country to be bypassed in the coming decades by the rest of the world as the solar system is colonized and settled.

Check it out.

The landing site of NASA’s next Mars lander

6:55 pm

InSight's landing site on Mars

InSight, NASA’s next Mars lander scheduled to launch later this year (two years late), is aiming for a landing site in a region called Elysium Planitia, a flat plain north of the equator.

InSight’s scientific success and safe landing depends on landing in a relatively flat area, with an elevation low enough to have sufficient atmosphere above the site for a safe landing. It also depends on landing in an area where rocks are few in number. Elysium Planitia has just the right surface for the instruments to be able to probe the deep interior, and its proximity to the equator ensures that the solar-powered lander is exposed to plenty of sunlight.

The target area is centered at 4.5 N latitude and 135.9 East longitude. If you zoom in on that latitude and longitude at the archive of Mars Reconnaissance Orbiter (MRO) high resolution images, you get the red blob on the right, which shows how many images they have taken of this area in preparation for InSight’s mission. The X indicates the location of lat/long above.

Below the fold is a reduced version of the MRO image for the center of this target area. The black spots near the center are thought to be a recent crater impact site. In general, this image shows an area with more features than the region around it. Most of the landing area of Elysium Planitia is a featureless flat plain with scattered small craters. Since InSight is not a rover, where it lands will be where it does its research, so there was no reason to pick a site with lots of interesting surface features. Moreover, since InSight is focused not on studying the surface but the interior geology of Mars, it matters little what the surface looks like anyway. One instrument will be a seismograph, while another will insert a thermometer about sixteen feet into the ground to measure the interior temperature.
