A galactic cloud

A galactic cloud
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope. It shows what scientists dub a lenticular galaxy, with features that put it somewhere between a spiral galaxy and an elliptical (which has no structure a appears instead a cloud of stars), sitting about 73 million light years away.

NGC 3156 has been studied in many ways … from its cohort of globular clusters, to its relatively recent star formation, to the stars that are being destroyed by the supermassive black hole at its centre.

Why this galaxy has no spiral arms is somehow related to its age and its central black hole, but the detailed theories that astronomers have to explain this are far from confirmed.

The image is interesting also because of its lack of foreground stars or background galaxies. Its location in the sky explains this, as Hubble was looking at right angle to the Milky Way’s galactic plane, essentially looking directly into the vast emptiness between the galaxies.

Two launches today, one by ULA and one by China

Today there were two successful launches. First China launched a remote sensing satellite using its Long March 6 rocket that lifted off from its Taiyuan spaceport in the south of China.

No word on where the rocket’s lower stages and four strap-on boosters crashed inside China.

Shortly thereafter, ULA used its Atlas-5 rocket to place a reconnaissance satellite into orbit for the National Reconnaissance Office (NRO), lifting off from Cape Canaveral.

For ULA, this was only its second launch in 2023. The leaders in the 2023 launch race are now as follows, with China’s total corrected:

63 SpaceX
42 China
12 Russia
7 Rocket Lab
7 India

In the national rankings, American private enterprise now leads China in successful launches 73 to 42. It also now leads the entire world combined, 73 to 67, while SpaceX by itself now trails the rest of the world (excluding American companies) only 63 to 67.

CORRECTION: Hat tip to reader John Foley (see his comment below), who noted that China’s total appeared to be one short. I went back and discovered I had missed a March 22, 2023 launch of a Kuaizhou 1A rocket from the Jiujian spaceport, placing four weather satellites in orbit. I have now added that launch to China’s total, and corrected the other numbers.

The panorama above, cropped, reduced, sharpened, and annotated to post here, was created on September 6, 2023 from eleven pictures taken by the right navigation camera on the Mars rover Curiosity.

This mosaic looks south, into the slot canyon dubbed Gediz Valles. The red dotted line on the panorama as well as the overview map to the right indicates the planned route the science team plans on traveling as it sends Curiosity higher and higher on Mount Sharp. On the overview map Curiosity’s present position is indicated by the blue dot. The yellow lines show the approximate area covered by the panorama above.

As noted in today’s update from the science team:

The rover is currently driving across bumpy terrain consisting of rounded bedrock sticking up between dark sand and drift as she drives south, and slightly uphill, along the Mt. Sharp Ascent Route. Due to the rugged ground, the rover sometimes ends her drive with a wheel or two perched on a rock.

When the rover’s placement prevents use of the arm, the scientists have it do other things, such as take more images of the many layers on Kukenan.

As rocky as this future route is, it appears it is less rocky than earlier terrain, which the science team found impossible to traverse requiring several route detours. Thus, the pace forward has been a bit faster lately.

Good news? FAA issues own report on April Starship/Superheavy launch

The FAA today closed out its own investigation into the April test launch failure of SpaceX’s Starship/Superheavy rocket, stating that it found “63 corrective actions SpaceX must take” before another launch license will be issued.

Corrective actions include redesigns of vehicle hardware to prevent leaks and fires, redesign of the launch pad to increase its robustness, incorporation of additional reviews in the design process, additional analysis and testing of safety critical systems and components including the Autonomous Flight Safety System, and the application of additional change control practices.

It is not clear how many of these corrections have already been completed by SpaceX. The FAA made it clear however that it does not yet consider its requirements to have been met.

The closure of the mishap investigation does not signal an immediate resumption of Starship launches at Boca Chica. SpaceX must implement all corrective actions that impact public safety and apply for and receive a license modification from the FAA that addresses all safety, environmental and other applicable regulatory requirements prior to the next Starship launch.

The timeline suggests FAA is demanding additional actions from SpaceX. The company submitted its own investigation report to the FAA on August 16th. The FAA then spent almost a month reviewing it, during which it almost certainly decided some of SpaceX’s corrections were insufficient. It has now followed up with its own report, listing additional actions required.

Remember, no one at the FAA is qualified or even in a position to do a real investigation. They are simply acting as a chess kibitzer on the sidelines, making annoying commentary based on less information than held by the players of the game (in this case SpaceX). Unlike a chess kibitzer, however, the FAA controls the board, and can force SpaceX to do its recommended moves, or declare the game forfeited by SpaceX.

If the FAA has required additional actions, we will find out in the next few days when SpaceX destacks Starship/Superheavy and rolls both back into the assembly building. It is also possible we instead shall have a few weeks of back-and-forth negotiations by phone, zoom, paper, and face-to-face meetings, whereby SpaceX engineers will be desperately trying to make FAA paper-pushers understand some of their engineering work which will eventually result in an agreement by the FAA to let SpaceX launch.

Remember, none of this kind of regulatory interference and investigation took place between SpaceX and the FAA during the Trump administration when SpaceX was flying a Starship suborbital test flight almost monthly. The heavy boot of regulation arrived soon after Biden. The two are closely linked.

GAO blasts NASA for purposely failing to control the budget of its SLS rocket

In a new report [pdf] released yesterday, the Government Accountability Office (GAO) strongly blasted NASA’s non-budgeting process for financing the costs for this SLS rocket, which appear specifically designed to allow those costs to rise uncontrollably.

This one sentence from the report says it all:

NASA does not plan to measure production costs to monitor the affordability of the SLS program.

That non-plan is actually in direct defiance of four different reports by both the GAO and NASA’s inspector general over the past decade, all of which found that NASA was not using standard budgeting practices with SLS and which all demanded it do so forthwith. As this new report notes in reviewing this history, in every case NASA failed to follow these recommendations, and instead created budgetary methods designed to instead obscure the program’s cost.

This report notes that NASA continues to do so.

Senate approves Biden’s FCC nominee, giving him a Democrat majority on FCC

FCC: now controlled by Democrats
The FCC, now controlled by the
power-hungry Democratic Party

Failure theater: The Senate yesterday voted 55 to 43 to approve Biden’s Federal Communications Commission (FCC) nominee, Anna Gomez, thus giving the Democrats a 4 to 3 majority on the Commission.

This was Biden’s second nominee to the commission, with the first withdrawn when it was clear the Senate opposed the nominee.

Biden tried again in May with the nomination of Gomez, a State Department digital policy official who was previously deputy assistant secretary at the US National Telecommunications and Information Administration (NTIA) from 2009 to 2023. A lawyer, Gomez was vice president of government affairs at Sprint Nextel from 2006 to 2009 and before that spent about 12 years at the FCC in several roles.

Gomez got through the confirmation process with relative ease, though most Republicans voted against her. Both parties seem to expect the FCC to reinstate net neutrality rules now that Democrats will have a majority.

Imposing net neutrality is essentially socialism/communism for the internet. It will squash competition, cost a fortune, and eventually be used as well to squelch dissent online (which translates into silencing conservatives).

From the perspective of space, the majority on the FCC is likely very bad news as well, for several reasons. » Read more

Layered glaciers in two small Martian craters

Layered glaciers in two small Martian craters
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on April 7, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what planetary scientists label somewhat vaguely as “layered deposits,” because though the features inside both of these craters strongly resemble glacial ice features, until this is confirmed a good scientist remains skeptical.

I can be more bold, and call the layers glacial in both of these small and very shallow craters (less than a 100 feet deep). To explain this it is important to understand that the lighting and shadows make it hard to distinguish the high points of these layers. Based on the elevation data from MRO, the ground descends to the south, and the mesa in the southern half of each crater’s floor is actually far below the layers and material to the north.

This elevation data suggests that the layered material is surviving best against the crater’s northern interior wall, which at this latitude, about 36 degrees south, will be in shadow the most.

Ingenuity flies on, completing its 57th flight

Overview map
Click for interactive map

On September 3, 2023 Ingenuity successfully completed its 57th flight on Mars, traveling 713 feet for two minutes and nine seconds. As noted at the tweet at the link, the helicopter has now accumulated more than 100 minutes of flight time.

As it has on almost all its recent flights, the helicopter flew a slightly longer distance for slightly longer that its flight plan, probably because it was taking time to find a safe landing spot.

The green dot on the overview map above shows Ingenuity’s new location. It has moved west and north of Perseverance, following the rover’s planned route as indicated by the red dotted line. The blue dot marks Perseverance’s present location. The yellow lines indicate the approximate area of the mosaic below, just released by the Perseverance science team, taken on July 8, 2023 by the rover’s high resolution camera and cropped and reduced to post here. It shows us the rover’s eventual path forward, into that mountain gap.

MOXIE completes its last run on Mars, producing oxygen from the atmosphere

The MOXIE instrument on the rover Perseverance in Jezero Crater on Mars has completed its sixteenth and last operational run, once again demonstrating that oxygen can be extracted from the Martian atmosphere in sufficient quantities to supply a future colony of humans.

Since Perseverance landed on Mars in 2021, MOXIE has generated a total of 122 grams of oxygen – about what a small dog breathes in 10 hours. At its most efficient, MOXIE was able to produce 12 grams of oxygen an hour – twice as much as NASA’s original goals for the instrument – at 98% purity or better. On its 16th run, on Aug. 7, the instrument made 9.8 grams of oxygen. MOXIE successfully completed all of its technical requirements and was operated at a variety of conditions throughout a full Mars year, allowing the instrument’s developers to learn a great deal about the technology.

Future MOXIEs will likely be larger in scale, even more efficient, and include methods for liquifying and storing any oxygen produced, though for producing a breathable atmosphere for Martian colonists all that would be needed would be an enclosed habitat. An operating MOXIE-type oxygen generator could fill it.

Targeted layoffs at Blue Origin

It appears that the upper management at Blue Origin has finally realized that a large Human Resource (HR) department contributes no real productive quality to a company, and in fact usually acts to reduce the company’s productive capabilities. According to reports from some company employees, it has begun to downsize this division.

Micah Thornton, a production control specialist at Blue Origin, wrote on LinkedIn that β€œseveral people from the Blue Origin Space Human Resource/Talent Acquisition team have been let go due to downsizing.” Several other employees wrote that they were laid off on Tuesday and are seeking new roles elsewhere.

This could be a very good sign for Blue Origin, or it could mean nothing. Other than periodically flying its reusable New Shepard suborbital spacecraft, the company’s main accomplishment since its formation more than two decades ago has been to establish a reputation as an unfocused operation unable to get its most important projects completed on time. Having a big HR department likely helps explain that history, and getting it reduced suggests management might be trying to get the company focused on its real mission.

Or not. HR employees are not engineers. Shifting them to other positions (which it appears the company is doing) simply rearranges the deck chairs on the Titanic.

We shall have to wait and see what transpires next. But then, that is all we have been doing in connection with Blue Origin for the past seven years.

China’s Long March 4C rocket launches classified remote sensing satellite

China’s three-stage Long March 4C rocket today (early morning on September 7th in China) successfully placed a classified remote sensing satellite into orbit, lifting off from China’s Jiuquan spaceport in the Gobi Desert.

This launch occurred prior to Japan’s H-2A launch, but I am only catching up with it now. As always, China’s state run press released little information, including where the first and second stages crashed inside China. All three stages of the Long March 4C use very toxic hypergolic fuels, so if those stages landed near habitable areas, there will be significant risk to bystanders.

The leaders in the 2023 launch race:

62 SpaceX
40 China
12 Russia
7 Rocket Lab
7 India

In the national rankings, American private enterprise still leads China in successful launches 71 to 40. It also still leads the entire world combined, 71 to 65, while SpaceX by itself now trails the rest of the world (excluding American companies) only 62 to 65.
