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.

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

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.

Dragon Endeavour undocks from ISS to bring 4 astronauts home

8:48 am

After more than a month delay resulting first from the issues with Starliner and then by poor weather in the splashdown zones, SpaceX’s Endeavour capsule today finally undocked from ISS, with a planned splashdown on October 25, 2024 at approximately 3:29 am (Eastern) off the coast of Florida. I have embedded the live stream of that splashdown below.

The capsules brings home three Americans and one Russian after a seven-month-long mission.

Review of the four private space stations presently under construction

8:41 am

Link here. The review provides a nice summary of the status of all four stations, being built by Axiom, Vast, and consortiums led by Blue Origin (Orbital Reef) and Voyager Space (Starlab).

The article included one piece of new news, based on recent stories suggesting major financial issues at Axiom:

As a result of these issues, the Axiom Station is believed to have been downsized to two modules from the originally planned four. There will be a reduced research capability from this arrangement compared to what was expected. However, it remains to be seen if additional capability can be added after the station becomes operational.

The original plan had been to separate the station from ISS once all four modules were launched. Whether it will be able to do so, flying independent of ISS’s systems with only two modules is unclear.

A pointy mesa once washed by theorized Martian ocean

A pointy mesa on Mars
Click for original image.

Today’s cool image returns to the same region yesterday’s cool image visited. The picture to the right, cropped, reduced, and sharpened to post here, was taken on July 21, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It was clearly taken to get a close look at this unusual pointy mesa.

MRO elevation data says this mesa is about 800 feet height. The color difference between the north and south flanks suggests the accumulated presence of dust on the north, suggesting the prevailing winds here come from the northeast and blow to the southwest. This conclusion is reinforced by the dark accumulated dust found in the southwest quadrants of all the crater floors in the full image. The wind blows this dust into the craters, where it gets trapped against the southwest crater wall.

Note the mesa’s wide base, with one crater partly eaten away on its eastern edge. The overall shape of this base suggests that it was carved by some flow coming from the southwest, as indicated by the arrow.

A slight bend in one boom delays NASA solar sail flight

9:07 am

Even though NASA’s solar sail test mission, dubbed the Advanced Composite Solar Sail System (ACSSS), successfully unfolded its giant sail in late August, engineers have not yet reactivated the sail’s attitude control system because they have detected a slight bend in one of the sail’s four booms.

While the solar sail has fully extended to its square shape roughly half the size of a tennis court, the mission team is assessing what appears to be a slight bend in one of the four booms. This likely occurred as the booms and sail were pulled taut to the spacecraft during deployment. Analysis indicates that the bend may have partially straightened over the weeks since boom deployment, while the spacecraft was slowly tumbling.

The attitude control system was turned off as planned during the deployment, allowing the sail to slowly tumble. It has been kept off longer than expected because the tumbling appears to be helping straighten the bend.

Once the control system is reactivated, the mission will then attempt to use the sail to change its orbit, to actually fly in space using sunlight like the wind.

ULA begins stacking Vulcan for military launch, anticipating Pentagon approval

8:56 am

Though the Space Force is still reviewing the nozzle issue on the second flight of ULA’s Vulcan rocket and has not yet certified the rocket for military operational launches, ULA has begun stacking the next Vulcan for an anticipated military launch of a national security satellite.

On Monday [October 21], ULA shared photos of the 109.2-foot-long (33.3 m) booster being hoisted into the Vertical Integration Facility to begin the stacking process. In the days and possibly weeks to come, the 38.5-foot-long (11.7 m) Centaur 5 upper stage will be added along with four solid rocket boosters and the payload fairings.

It appears that the military has accepted Vulcan for this launch because — despite the nozzle falling off of
a strap-on side booster — the rocket was successful in placing its payload in its precise orbit. The Space Force is simply completing the paperwork required for certification.

No date however has been set, but the company hopes to complete two military Vulcan launches in 2024, so it won’t be that far in the future.

The obvious visual evidence for assuming Mars once had catastrophic floods

The obvious visual evidence of past catastropic floods on Mars
Click for original image.

Since the first comprehensive orbital data of Mars was sent back in the early 1970s by Mariner 9, scientists have generally concluded that many of the features seen at the eastern end of the giant Valles Marineris canyon were caused by one or several catastrophic floods.

The picture to the right, rotated, cropped, and reduced to post here and taken on July 26, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), provides a good example of why the scientists have come to that conclusion. It shows what the camera team labels a “streamline feature surrounding crater.” I have added the arrows to indicate the presumed direction of flow. The flow went around this 2.5-mile-wide unnamed crater because the impact had compacted it, making it resistent to erosion. The flow however was strong and large enough to wash away the plateau on which the crater sits, as well as cutting into the crater’s southwest rim. In addition, the rim on the southeast was also cut through at some point, this time from what might have been flow eddies as the flood pushed past.

Hence, the theory of catastrophic floods.
