Successful deployment of large array antennas on all five AST’s satellites

12:48 pm

AST SpaceMobile has now successfully unfolded the large array antennas on all five the satellites it launched in September, and did so six weeks ahead of schedule.

“The unfolding of the first five commercial satellites is a significant milestone for the company. These five satellites are the largest commercial communications arrays ever launched in low Earth orbit,” commented Abel Avellan, founder, Chairman and CEO of AST SpaceMobile, in a statement. “It is a significant achievement to commission these satellites, and we are now accelerating our path to commercial activity.”

The satellites are designed to act like cell towers in space, providing direct satellite-to-cellphone coverage and fill gaps in ground-based cell service. ATT has already signed a contract with AST to use these satellites.

Lab tests suggest water brines could also exist on large asteroids

12:28 pm

Gullies in crater on Vesta
Click for original image.

In attempting to explain the existence of flow features that have been found on the interior walls of craters on the asteroids Ceres and Vesta — as shown in the image above — scientists recently performed a laboratory experiment which determined that a mixture of water and salt could produce those gullies.

The team modified a test chamber at the Jet Propulsion Laboratory to rapidly decrease pressure over a liquid sample to simulate the dramatic drop in pressure as the temporary atmosphere created after an impact on an airless body like Vesta dissipates. According to Poston, the pressure drop was so fast that test liquids immediately and dramatically expanded, ejecting material from the sample containers.

“Through our simulated impacts, we found that the pure water froze too quickly in a vacuum to effect meaningful change, but salt and water mixtures, or brines, stayed liquid and flowing for a minimum of one hour,” said Poston. “This is sufficient for the brine to destabilize slopes on crater walls on rocky bodies, cause erosion and landslides, and potentially form other unique geological features found on icy moons.”

The press release makes it sound as if this result makes the existence of subsurface water ice more likely on such asteroids as Ceres and Vesta, but previous research from the Dawn asteroid probe made that fact very clear, especially for Ceres, years ago. All this does is provide some evidence of what might be one process by which these erosion gullies form.

Two cubesats on Hera signal home

10:07 am

Engineers on the ground have now established good communications with the two cubesats that are being carried by the European probe Hera on its way to the binary asteroids Didymos and Dimorphos.

“Each CubeSat was activated for about an hour in turn, in live sessions with the ground to perform commissioning – what we call ‘are you alive?’ and ‘stowed checkout’ tests,” explains ESA’s Hera CubeSats Engineer Franco Perez Lissi.

…Travelling with Hera are two shoebox-sized ‘CubeSats’ built up from standardised 10-cm boxes. These miniature spacecraft will fly closer to the asteroid than their mothership, taking additional risks to acquire valuable bonus data.

Juventas, produced for ESA by GOMspace in Luxembourg will make the first radar probe within an asteroid, while Milani, produced for ESA by Tyvak International in Italy, will perform multispectral mineral prospecting.

This use of small cubesats in conjunction with a larger interplanetary probe is becoming increasingly routine, and provides a cheap and efficient way to increase the data and information obtained. Note too that both cubesats were apparently built entirely by private companies, thus establishing their creditionals as providers of interplanetary probes.

ExoAnalytic now identifies more than 500 pieces from Intelsat satellite breakup

9:57 am

The private commercial space tracking company ExoAnalytic has now identified more than 500 pieces from Intelsat 33e satellite breakup.

Some of the smaller debris might actually quickly disappear as these pieces are possibly bits of solid fuel that will evaporate.

Much of the press has suddenly decided this failure is all Boeing’s fault, because the satellite was built by that company a decade ago. This seems a bit unfair, since Boeing’s problems now seem far removed from its design and construction of satellites then. At the same time one must wonder. Boeing built four of these type satellites for Intelsat, and the first was lost in 2019 when either it was hit by a meteor or had “a wiring flaw, which led to an electrostatic discharge following heightened solar weather activity.”

That means two of the four satellites have been lost, though the second, 33e, didn’t break-up until twelve years of operation, almost its expected lifespan. Furthermore, the other two satellites are still working fine.

All in all, that suggests to me that though there may be a technical cause that can be traced back to the company, it is more likely we are simply seeing a random expression of the dangers of space to engineering, by anyone.

New issue with Voyager-1

9:41 am

The Voyager missions
The routes the Voyager spacecraft have
taken since launch.

According to a NASA report yesterday, engineers are dealing with a new technical problem that has occurred Voyager-1, flying out beyond the edge of the solar system.

On Oct. 16, the flight team sent a command to turn on one of the spacecraft’s heaters. While Voyager 1 should have had ample power to operate the heater, the command triggered the fault protection system. The team learned of the issue when the Deep Space Network couldn’t detect Voyager 1’s signal on Oct. 18.

The spacecraft typically communicates with Earth using what’s called an X-band radio transmitter, named for the specific frequency it uses. The flight team correctly hypothesized that the fault protection system had lowered the rate at which the transmitter was sending back data. This mode requires less power from the spacecraft, but it also changes the X-band signal that the Deep Space Network needs to listen for. Engineers found the signal later that day, and Voyager 1 otherwise seemed to be in a stable state as the team began to investigate what had happened.

Then, on Oct. 19, communication appeared to stop entirely. The flight team suspected that Voyager 1’s fault protection system was triggered twice more and that it turned off the X-band transmitter and switched to a second radio transmitter called the S-band. While the S-band uses less power, Voyager 1 had not used it to communicate with Earth since 1981. It uses a different frequency than the X-band transmitters signal is significantly fainter. The flight team was not certain the S-band could be detected at Earth due to the spacecraft’s distance, but engineers with the Deep Space Network were able to find it.

Though communications with the spacecraft continue, no data can be downloaded and work is essentially suspended while engineers troubleshoot why Voyager-1 kept initiating its fault system.

It is amazing that communications were still possible using the S-band after more than forty years. I would bet that no engineers from then still work at the Deep Space Network. Kudos to the engineers there now for finding the signal.

NASA picks nine lunar south pole candidate sites for Artemis-3 manned landing

10:37 am

The Moon's south pole, with candidate landing sites
Click for NASA’s original image.

NASA today revealed the nine candidate sites in the Moon’s south polar region for its Artemis-3 manned mission, presently targeting a 2026 launch date.

The map to the right shows the location of those nine sites, numbered in order of priority, as follows:

  • 1. Peak near Cabeus B
  • 2 . Haworth
  • 3. Malapert Massif
  • 4. Mons Mouton Plateau
  • 5. Mons Mouton
  • 6. Nobile Rim 1
  • 7. Nobile Rim 2
  • 8. de Gerlache Rim 2
  • 9. Slater Plain

The map also shows the planned landing sites for Intuitive Machine’s Athena lander in January 2025, and China’s Chang’e-7 lander in 2026, as well as where India’s Virkam lander touched down in 2023.

Cabeus B is likely the prime candidate site because its high elevation will make communciations easier, while placing it closer to the crater Cabeaus, which was impacted by the LCROSS mission in 2009 and found a significant signature of water in the ejecta plume of that impact.

To make a final decision NASA will be consulting all players, from the science community as well as the engineers. All of this however depends on other factors outside of science and engineering, mostly related to politics and practicality. The entire mission relies on the full version of the SLS rocket, the manned lunar version of SpaceX’s Starship, launched by Superheavy, and a working version of Lockheed Martin’s Orion capsule, none of which are presently flightworthy.

Old rockets clash with new rockets in Europe

9:35 am

Two stories today from Andrew Parsonson at his website Europeanspaceflight.com today illustrate the battle going on in Europe’s vast space bureaucracy over its future rocket development, and clearly tell us who is winning.

First Parsonson described a presentation put forth by Arianespace officials at an “Ariane-6 User’s Club” meeting two weeks ago, outlining the planned and proposed upgrades Arianespace intends for the Ariane-6 rocket over the next decade. All the upgrades are focused on increasing the rocket’s payloac capacity. None will make any of the rocket reusable in order to lower its high cost which makes it uncompetitive in the modern launch market.

What was significant about Parsonson’s report is that he also noted that many of these upgrades need to be approved by the European Space Agency (ESA), and its officials won’t make that decision until 2025 during a planned conference. Thus, this presentation by Arianespace was essentially a lobbying effort to convince ESA to approve these upgrades.

Parsonson’s second story then told us what ESA is approving, right now.

The European Space Agency has selected Rocket Factory Augsburg, The Exploration Company, ArianeGroup, and Isar Aerospace to develop reusable rocket technology.

On 9 October, ESA held its Future Space Transportation Award Ceremony in Paris. During the event, the agency announced the four awardees under two initiatives focused on the development of reusable rocket technology: the Technologies for High-thrust Reusable Space Transportation (THRUST!) project and the Boosters for European Space Transportation (BEST!) project.

Except for ArianeGroup, these are new startups. The German companies Rocket Factory and Isar are developing their own rockets, while the French company Exploration has so far focused on making cargo capsules to supply future space stations.

ArianeGroup meanwhile is the joint partnership between Airbus and Safran that built and owns the Ariane-6, and actually has more say on its future than Arianespace, which is merely a government agency that in the past (but no more) managed and controlled all of Europe’s rockets. ArianeGroup hasn’t abandoned Ariane-6 by no means, but clearly is shifting its interests in new directions.

Interestingly, the final decisions on some of these reusable projects will be made at that same 2025 conference.

Want to bet that ESA at that conference shifts its focus from upgrading the non-reusable Ariane-6 and instead goes whole hog for reusability? I expect that, especially because all recent political signs at ESA has indicated no interest in maintaining Arianespace any longer. For example, ESA has taken the Vega family of rockets away from Arianespace and given it back to Avio, the Italian company that manufactures it. ESA has also returned management of French Guiana from Arianespace to France’s space agency, which owns the site.

Designed as the commercial arm of ESA, it no longer has a function, now that Europe is shifting from the Soviet-model of its rocket operation run by the government (Arianespace) to a capitalism model where competing independent companies provide products and services to that government.

ISRO head unveils new timeline for major missions

10:06 am

The head of India’s space agency ISRO, S. Somanath, yesterday unveiled a new timeline for several of that nation’s major missions, both manned and unmanned.

The new timeline is as follows:

  • 2025: NISAR: a joint Indian-American radar orbiter, long delayed
  • 2026: Gaganyaan-1, India’s first manned orbital mission
  • 2028: Chandrayaan-4, an unmanned sample return mission to the Moon
  • 2028: Chandrayaan-5, a joint lander-rover to the Moon

The last project will be done in partnership with Japan, with India building the lander and Japan the rover.

2028 will be a very busy year for India in space. The Indian government had previously announced that ISRO would launch in 2028 the first module of its space station as well as a Venus orbiter.

Unidentified astronaut from recent ISS mission released from hospital

9:54 am

Though NASA’s press release provided little informationto protect the astronaut’s privacy, including his or her name, the unidentified astronaut who was held overnight for observation after returning from a seventh-month stay on ISS mission has now been released from the hospital.

After an overnight stay at Ascension Sacred Heart Pensacola in Florida, the NASA astronaut was released and returned to NASA’s Johnson Space Center in Houston Saturday. The crew member is in good health and will resume normal post-flight reconditioning with other crew members.

This has happened before. Readapting to a 1G environment after months in weightlessness can be difficult, even if one does all the exercises required while in orbit.

SpaceX yesterday launched another 23 Starlink satellites

5:34 pm

SpaceX yesterday successfully launched 23 more Starlink satellites, its Falcon 9 lifting off from Cape Canaveral in Florida.

While the video link above says 23, a UPI report said the launch placed 22 satellites in orbit. I have no idea which is right, as the number of Starlinks on these launches range from 20 to 23.

The first stage completed its 19th flight, landing on a drone ship in the Atlantic.

The leaders in the 2024 launch race:

105 SpaceX
48 China
11 Russia
11 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 122 to 71, while SpaceX by itself now leads the entire world, including American companies, 105 to 88.

Space News buries the lede

9:42 am

In reporting the information revealed in an audio report of two SpaceX engineers to Elon Musk, Space News completely misses the main reason Musk posted this video.

The focus of Jeff Foust’s report is the technical problems the engineers revealed that occurred during the descent of Superheavy during the last flight. According to them, one particular parameter related to the Raptor engines was one second away from demanding an abort, whereby the rocket would not attempt to be captured by the tower chopsticks but instead crash along side it. In addition, these engineers reported the worrisome consequences when a chine on the booster ripped off shortly before landing.

All interesting, but the real reason Elon Musk posted this clip from a much longer audio report is what one engineer says about two thirds of the way through:

Given that that is the first launch [#6] in a long time — well, really, ever — that we’ve not been FAA driven, we’re trying to go do a reasonable balance of speed and risk mitigation on the booster, specifically.

Musk wished everyone to know without question the perspective of his employees when it comes to the red tape of the FAA. It hasn’t been our imagination. For the past three years the FAA has determined the test schedule, slowing it down significantly while costing SpaceX a lot of money.

Space News, which generally has been in the tank for the regulators and the FAA, puts this quote to the very end of its article, almost as an aside. I suspect the outlet would have liked to leave it out.

I have posted the video below, so my readers can listen at their leisure.

One unidentified astronaut hospitalized after return to Earth today

9:04 pm

Though NASA has released very little information, including the indentity of the astronaut, one of the four crew who were brought back to Earth early today has ended up in the hospital.

NASA said Friday one its astronauts is in a hospital in Florida for medical observation after a “normal” predawn splashdown in the Gulf of Mexico inside a SpaceX capsule.

The mission’s other three crew members were cleared to return to their home base at Johnson Space Center in Houston after their own medical evaluations, NASA said.

The hospitalized astronaut “is in stable condition and under observation as a precautionary measure,” a NASA spokesperson said in a statement. The agency did not identify the astronaut or provide any more details about their condition, citing medical privacy protections.

That the other three astronauts returned to their home base at Johnson in Houston strongly suggests the hospitalized astronaut is the one Russian, Alexander Grebenkin, Normally Russians head back to Russia relatively quick after landing.

This remains speculation. We will have to wait for more information.

Gina Lollobrigida – Pagan dance

An evening pause: I think this makes a great start to the weekend. Clips from the 1959 movie Solomon and Sheba, centered on Gina’s pagan dance as Sheba, and edited to a piece of music by Dead Can Dance, called Cantara, which the youtube website labels “genuinely pagan music.” If you want to see the original film, go here and go to about 90 minutes. In the original, God steps in to stop all this hanky-panky.

Taking the day off…

12:19 pm

Yesterday I came down with a head cold, which is draining me of energy. I am going to take a few hours off to take a nap. I should post some more later in the day but don’t expect much.

A sidenote: When I mentioned I had a head cold to someone, the first question that person asked was “Covid?” I laughed and responded, “Who cares? Covid has been nothing more than a cold since around 2021.”

This obsession with Covid has got to stop. From a infectious disease perspective the only valuable thing it taught us is that every new and harsh flu strain that comes through eventually mutates downward utnil it is nothing more than the common cold. Covid did exactly that, no matter how much the Chicken Littles of the world tried to claim otherwise.

Boeing considering selling its space division

11:55 am

According a Wall Street Journal exclusive today (behind a paywall), the company is now exploring the possibility of selling off its space division.

The NASA business that Boeing is exploring a sale of includes the troubled Starliner space vehicle and operations that support the International Space Station, but excludes the unit building NASA’s Space Launch System, the newspaper reported.

The U.S. planemaker’s shares rose 0.6% in afternoon trading.

Boeing’s space division includes its Starliner capsule and its work on NASA’s SLS rocket, as well as building many of the modules on ISS and operating it for NASA.

If this is so, it appears the new CEO, Kelly Ortberg, has decided that in order to get the company back on track it needs to focus on Boeng’s first and central business, building airplanes. Space is a distraction that is not helping the company bottom line right now in any way. Furthermore, NASA in 2020 told Boeing it would not entertain any new project bids from the company because its past bids were so poorly conceived. That decision remains in effect now, four years later. Since then Boeing has only have gotten a renewal contract to build more SLS rockets, plus a contract to develop a new airplane wing, but little else.

Using spectroscopic data, astronomers create 3D map of ancient supernova remnant

10:55 am

Supernova 1181
Click for original image.

Astronomers have now createdsdft a 3D map of the remnant formed by a supernova that occurred in 1181, using detailed spectroscopic data to determing which remnant filaments are moving towards us and which are moving away.

The picture to the right is from figure 1 of their paper, and shows how the filaments radiate out from the center in straight lines, something that is unusual for such remnants. It was taken in 2023 by a ground-based telescope at Kitt Peak in Hawaii. From simple optical data it is impossible however to determine which filaments are in the rear, expanding away from us, and which are in the front, expanding towards us.

To probe the three-dimensional structure of the supernova remnant, the astronomers turned to KCWI, an instrument that can capture multiwavelength, or spectral, information for every pixel in an image. This is like breaking apart the light captured in every pixel into a rainbow of colors. The spectral information enabled the team to measure the motions of the filaments poking out from the center of the explosion and ultimately create a 3D map of the structure. The filament material that is flying toward us shifted toward the blue higher-energy portion end of the visible spectrum (blue-shifted), while light from material moving away from us shifted toward the red end of the spectrum (red-shifted).

…The results showed that the filament material in the supernova is flying outward from the site of the explosion at approximately 1,000 kilometers per second. “We find the material in the filaments is expanding ballistically,” says Cunningham. “This means that the material has not been slowed down nor sped up since the explosion. From the measured velocities, looking back in time, you can pinpoint the explosion to almost exactly the year 1181.”

The 3D information also revealed a large cavity inside the spindly, spherical structure in addition to some evidence that the supernova explosion of 1181 occurred asymmetrically.

Using this data, they were able to create that 3D map, shown below in a coarse animation video.

Sutherland spaceport submits another revised plan to local council

10:41 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea.

We’re from the government and we are here to help you! The long-delayed proposed Sutherland spaceport on the north coast of Scotland has now submitted another revised plan to its local Highlands council for approval.

The amended plans for Sutherland Spaceport include a smaller launch pad and launch services facility, and realigning an access road to avoid an area of deep peat. Highland Council planners said the changes would mean reducing the amount of peat that would have to be excavated by more than half. The soil is seen as important because it absorbs CO2.

Highland councillors meeting next week have been asked to approve the amendments. In a report, officials said the amount of peat to be dug up could be cut from 24,046 cubic metres to 9,895 cubic metres.

This is the second time the spaceport has had to submit revised plans to this council. It did so in December 2023, but apparently the council was not satisfied.

Meanwhile Sutherland’s main launch customer, Orbex, has still not gotten its launch licence from the UK’s Civil Aviation Authority, first applied for in February 2022. Orbex, which has a fifty year lease at Sutherland and has built its rocket factory nearby, had planned to do its first test launch of its Prime rocket two years ago. Didn’t happen.

Adding to these bureaucratic delays, Anders Holch Povlsen, a local billionaire — who is an investor in the Saxaford spaceport on the Shetland Islands — in July 2024 filed what appeared to be an absurd harrasment lawsuit against Sutherland, and this was the second time he had done so.

I think Orbex picked the wrong spaceport horse in this race, and is likely going to be killed by this red tape and opposition.

The uncertainty of science: New research suggests first image in ’22 of Milky Way’s central black hole is likely not accurate

10:25 am

Sagittarius A*
The original interpretation. Click for full image.

The new interpretaion
The new asymmetrical interpretation. Click for original image.

Surprise, surprise! A new analysis of the data behind the 2022 false-color radio image of the supermassive black hole at the center of the Milky Way, posted to the right, suggests that image was not accurately interpreted from the data.

Astronomers led by the National Astronomical Observatory of Japan (NAOJ) say their analysis points at Sagittarius A* having an elongated accretion disk, as opposed to the ring-like “doughnut” image released in 2022 by an international team called the Event Horizon Telescope (EHT) collaboration.

The EHT image shows a central dark region where the hole resides, circled by the light coming from super-heated gas accelerated by immense gravitational forces.

But a new paper published today in Monthly Notices of the Royal Astronomical Society suggests that part of this appearance may actually be an artefact because of the way the image was put together. … Assistant professor Miyoshi Makoto, of the NAOJ, said: “Our image is slightly elongated in the east-west direction, and the eastern half is brighter than the western half. We think this appearance means the accretion disk surrounding the black hole is rotating at about 60 per cent of the speed of light.” He added: “Why, then, did the ring-like image emerge? Well, no telescope can capture an astronomical image perfectly. We hypothesise that the ring image resulted from errors during EHT’s imaging analysis and that part of it was an artefact, rather than the actual astronomical structure.”

It must be noted that this false color radio image was assembled from eight different radio telescopes across the globe, and to bring the data together required a great deal of massaging. While most astronomers appear to favor the top picture, it is just as likely that the bottom picture is a better representation. Either way, both must be considered in any future studies of Sagittarius A*’s environment and structure.

Four astronauts complete 7-month mission and return to Earth

9:54 am

In the early hours of the morning today SpaceX’s Endeavour capsule safely splashed down in the Gulf of Mexico near Pensacola, Florida, bringing three Americans and one Russian back from ISS after seven months in orbit.

After launching March 3 on a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center in Florida, NASA astronauts Matthew Dominick, Michael Barratt, and Jeanette Epps, as well as Roscosmos cosmonaut Alexander Grebenkin, spent 232 days aboard the space station.

Recovery teams from NASA and SpaceX quickly secured the spacecraft and assisted the astronauts during exit. The crew now will head to NASA’s Johnson Space Center in Houston, while the Dragon spacecraft will return to SpaceX facilities at Cape Canaveral Space Force Station in Florida for inspection and refurbishment for future missions.

This completed Endeavour’s fifth flight to ISS, ranging in length from 17 to 235 days in length.

SpaceX rolls out the next Superheavy for sixth test orbital launch

9:59 am

SpaceX in a tweet on October 22, 2024 announced the roll out to the launch tower of the next Superheavy to be used in the sixth orbital test flight, only nine days after that launch tower had successfully caught a Superheavy at the end of the fifth orbital test flight.

Though no launch date has been announced, the company is clearly wants to do it soon. Though its present launch license allows it go when ready, it remains unclear whether it will get that approval from the FAA when requested. FAA upper management has repeatedly indicated a desire to delay its approvals to SpaceX, and until there is a change in the White House — thus forcing a change in that FAA upper management — there is no reason to expect the agency to change its behavior.

Spaceport startup SUAS Aerospace signs deal to launch small suborbital rocket from west coast of Ireland

9:49 am

SUAS's proposed spaceport plan
Click for original image.

The Irish spaceport startup SUAS Aerospace has now signed a partnership deal with the Netherlands rocket startup T-Minus Engineering to launch a small suborbital rocket from west coast of Ireland in order to demonstrate the viability of Ireland as a potential spaceport location.

According to this report, “T-Minus will provide its Dart rocket for the launch. Dart stands at 3.5 metres and is capable of carrying payloads of up to 3.5 kilograms to a maximum altitude of 200 kilometres.”

Though SUAS has raised €5 million in private investment capital to push its project to build two launch sites within Ireland, it has not made it clear the exact locations of these sites, other than indicating it wants to place them at two locations on Ireland’s west coast, as shown by the company graphic to the right. I suspect it does not yet have rights to the land, and its lobbying effort is largely focused on getting government help to obtain those rights, either on public or private land.

For example, its press release does not provide any details on where this suborbital launch will occur. I am not even sure the company knows. It might simply arrange some coastal location, simply to make possible this demonstration launch, even if that place is not the actual location of its proposed spaceport.

JPL unveils website for viewing all high resolution imagery so far taken of Europa

9:29 am

In anticipation of the eventual arrival of Europa Clipper in orbit around Jupiter to begin its close investigation of that planet’s moon Europa, JPL yesterday unveiled a website that allows a view to quickly find and review all the high resolution imagery so far taken of Europa by the Jupiter orbiters, Voyager, Galileo, and Juno.

You can visit the Europa Trek portal website here.

The announcement touts the webpage’s ability to take viewers on “fly-overs” of the terrain, but that’s just a bell and whistle claim of little importance. More significant is the easy access this webpage provides to all that imagery, organized in context with a global map of the planet. Not only can anyone quick find interesting features, you can do so within the global context of the whole planet. In addition, the page provides detailed commentary about each image.

When Europa Clipper arrives this portal will be invaluable in deciphering the significance of every new image and datapoint.

Boeing forced to take another $250 million charge on Starliner

9:19 am

Because of the continuing problems getting its Starliner manned capsule operational, Boeing has now taken another $250 million charge on the project, raising the total spent of its own money to $1.85 billion.

The company’s original fixed-price contract with NASA to deliver the capsule was $4.2 billion. The bulk of that won’t be paid until Starliner begins flying astronauts commercially, and NASA has now delayed that until 2026 at the earliest. The company’s new CEO, Kelly Ortberg, has now made it clear that he is focused on imposing changes to fix the bankrupt engineering management culture that has caused it so many failures in so many of its recent projects, not just Starlner. In his remarks announcing the company’s third quarter results, he said this:

The trust in our company has eroded. We’re saddled with too much debt. We’ve had serious lapses in our performance across the company which have disappointed many of our customers.

In addressing these issues Ortberg listed a whole range of changes, many of which focused on getting managers more closely involved in design and construction, or as he said, management needs “to be on the factory floors, in the back shops and in our engineering labs.”

Whether he will succeed is unknown. Its factory workers today rejected a new contract offer, continuing their now six-week strike that has halted work on company’s airplane business. In addition, Boeing reported a loss of $6 billion in that third quarter report.

One thing Ortbeg did make clear this week however: Boeing is not walking away from its Starliner contract with NASA. At a minimum it will complete that initial fixed price contract. Whether it will go on to fly more Starliner missions however Ortberg left open. I suspect he remains in negotiation with NASA over this issue.
