China launches X-ray space telescope

9:25 am

China early today successfully used its Long March 2C rocket to launch its new Einstein X-ray space telescope, built in partnership with the European Space Agency (ESA). The rocket lifted off from the Xichang spaceport in the southwest of China.

Astronomers will use the telescope to study the high energy released by during supernovae. It will also be used to study black holes and other high energy deep space phenomenon.

Meanwhile, the lower stages of the rocket, which use toxic hypergolic fuels, fell somewhere in China. No word if they landed anywhere near habitable areas.

The 2023 launch race:

3 SpaceX
2 China

Artemis lunar program likely to be delayed further

9:14 am

Surprise! According to two different news outlets today (Reuters and CNN) citing anonymous sources, NASA is about to announce further delays in its manned Artemis program to put humans back on the Moon.

Both reports state that the second Artemis mission, the first with humans on board, will not take place this year as NASA has been saying, but will be delayed until 2025. The third mission, the intended manned landing on the Moon, will be further delayed until 2026. Furthermore, Reuters reports that the actual landing might be delayed until the fourth mission, “giving SpaceX and other contractors more practice before making the first such landing in half a century.”

None of these dates will be met. I predict that further delays will be announced next year and the year after that, pushing all these missions back again, in small increments, even though it is obvious now that the entire program is years from making those first manned flights.

There are numerable problems. First the SLS rocket is so cumbersome it takes many months to assembly for launch. Any issues along the way cause delays. Second, battery problems were detected during testing of the Orion capsule to fly, requiring their replacement.

Third, and most important, the lunar landing requires NASA’s Lunar Gateway and SpaceX’s Starship. Gateway is nowhere near ready. All of its multiple components are still being built, with none yet launched.

SpaceX’s Starship is undergoing testing, but those test flights are being hampered by red tape at the FAA and elsewhere in the federal government. SpaceX had planned to do as many as six test flights per year. Right now the federal bureaucracy is slowing that plan to only one to two test flights per year. Under that restriction, the Starship lunar lander won’t be ready for years.

Pushing the manned lunar landing back one mission makes some sense, but the entire program remains fraught with great risks. Because SLS is so expensive and difficult to fly, NASA can’t afford to do the correct number of unmanned test missions before sending humans on it. For example, the first manned flight will be the first using the environmental system in Orion designed to keep people alive. Yet, that mission intends to circle the Moon with people on board.

For context, note that this program was first announced by George Bush Jr in 2004, with a goal of putting humans on the Moon by 2015. NASA did not even fly the first unmanned SLS/Orion mission until 2022.

Right now, if NASA gets a human on the Moon before 2030 it will be doing well.

Layered volcanic vent on Mars

Layered volcanic vent on Mars
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on August 31, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows what the science team labels as a “vent near Olympica Fossae.”

The grade within the fissure is downhill to its center. Outside the vent the grade is downhill to the north and south, with the overall grade sloping to the west as well. Note the layers on each side of the depression. Each indicates another volcanic flood event that laid down another layer of lava. At some point this vent either blew up through those layers, or it had remained opened during all those many events, the lava flowing out and acting like water to erode the layers on the north and the south.

As always, the scale of Martian geology is daunting, as shown by the overview map below.

Astrobotic’s Peregrine lunar lander suffers major failure

12:10 pm

According to updates by the engineering team running Astrobotic’s Peregrine lunar lander, launched early today by ULA’s Vulcan rocket, the lander’s propulsion system suffered a major failure shortly after activation.

After successfully separating from United Launch Alliance’s Vulcan rocket, Astrobotic’s Peregrine lunar lander began receiving telemetry via the NASA Deep Space Network. Astrobotic-built avionics systems, including the primary command and data handling unit, as well as the thermal, propulsion, and power controllers, all powered on and performed as expected. After successful propulsion systems activation, Peregrine entered a safe operational state. Unfortunately, an anomaly then occurred, which prevented Astrobotic from achieving a stable sun-pointing orientation.

The company later released an update, stating that the failure caused “a critical loss of propellant” that will make the mission impossible as planned. They are reassessing to see if they can come up with an alternate plan, but without sufficient fuel no lunar landing will be possible under any mission profile.

Peregrine is a smaller test version of Astrobotic’s larger Griffin lunar lander, which has contracts with NASA and ESA for later missions. This failure will likely impact those missions, forcing either delays or redesigns.

This mission was always an engineering test mission designed to prove out Astrobotic’s landing design, so experiencing a failure was not a surprise. The problem is that this failure occurred so soon after launch that it prevents the company from testing that landing design, at all.

Americans push back against government overreach with some real defiance

11:54 am

Are Americans finally waking up and emulating their country's founders?

Bring a gun to a knife fight: For the first time since 2020, when state and federal governments nationwide decided the Constitution and Bill of Rights no longer applied to them and began imposing a whole range of abusive illegal regulations and lockdowns and mandates and blacklisting on Americans everywhere, we are now finally beginning to see some real push back from ordinary people, in ways that leave these tinpot dictators no choice but to back down.

Two examples in the past week. First in St. Louis the city government (controlled by radical leftist Democrats) decided it was time to institute a new panic over COVID, likely to give them the ability to once again easily manipulate voting in 2024, by instituting a new city mask mandate. Though it only recommended strongly that everyone wear masks everywhere, its director of health Matifadza Hlatshwayo Davis said that masks were required of government employees if they were indoors or in a car with another person.

Davis’s problem was that, unlike 2020, almost no one obeyed her demands.

One spiral galaxy eating another

One spiral galaxy eating another
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 as part of an on-going survey of known pecular-looking galaxies. This pair is believed to be 570 million light years away. From the caption:

Galaxies are composed of stars and their solar systems, dust and gas. In galactic collisions, therefore, these constituent components may experience enormous changes in the gravitational forces acting on them. In time, this completely changes the structure of the two (or more) colliding galaxies, and sometimes ultimately results in a single, merged galaxy. That may well be what results from the collision pictured in this image. Galaxies that result from mergers are thought to have a regular or elliptical structure, as the merging process disrupts more complex structures (such as those observed in spiral galaxies). It would be fascinating to know what Arp 122 will look like once this collision is complete . . . but that will not happen for a long, long time.

From our viewpoint, the spiral galaxy at the top appears warped by the gravitational pull of the face-on spiral at the bottom, as if it is being sucked into the bottom galaxy. In truth, both galaxies are pulling on each other. If we could circle around and see them in three dimensions we would almost certainly see distortions in the bottom spiral as well.

Scientists: Suspended iron minerals floating in Venus’s atmosphere explain dark UV streaks

9:37 am

Venus as seen in ultraviolet by Mariner 10, February 5, 1974

The uncertainty of science: Since the mid-1970s scientists have been trying to figure out the cause of the dark streaks seen in the atmosphere of Venus when photographed in ultraviolet. The image to the right was the first such UV image, taken by Mariner 10 during its fly-by on its way to Mercury. These streaks are caused by some unknown material that absorbs the UV light.

Researchers have now proposed that two different iron-bearing minerals, floating in Venus’s atmosphere, are what cause these dark UV streaks. From the absract:

Our results demonstrate that ferric iron can react with sulfuric acid to form two mineral phases: rhomboclase [(H5O2)Fe(SO4)2·3H2O] and acid ferric sulfate [(H3O)Fe(SO4)2]. A combination of these two mineral phases and dissolved Fe3+ in varying concentrations of sulfuric acid are shown to be good candidates for explaining the 200- to 300-nm and 300- to 500-nm features of the reported unknown UV absorber.

Iron has been detected in the atmosphere previously, and is theorized could come from volcanic eruptions on the planet’s million-plus volcanoes.

This new hypothesis explaining the dark UV absorber however remains unconfirmed, and joins a list of other candidates for that absorber, many of which propose either iron or sulfur in different combinations. Because so little data really exists about the atmosphere of Venus, with what is known also uncertain, it is presently impossible to solve this mystery with confidence. The problem is made even more difficult in that scientists understand almost nothing about the chemistry of materials under the conditions seen in Venus’s atmosphere, which is extremely hot (800 degrees Fahrenheit) and very thick and dense (100 times that of Earth).

ULA’s Vulcan rocket successfully places payload in orbit on first launch

1:10 am

Vulcan at liftoff.

After four years of delay, mostly caused by delays at Blue Origin in delivering the two BE-4 engines used in the first stage, ULA’s Vulcan rocket finally completed its first launch early on January 8, 2024, lifting off from Cape Canaveral and successfully placing Astrobotic’s Peregrine lunar lander into orbit.

As of posting the upper stage had just deployed Peregrine, which will leave Earth orbit in about four days using its own engines. The upper stage has one more burn to send it into solar orbit, carrying the ashes of numerous people for the company Celestis.

The 2024 launch race:

3 SpaceX
1 India
1 China
1 ULA

For ULA, this launch is a very big deal. It is the first of two required in order for the Space Force to certify the rocket for future military launches. It also positions the company to begin the many launches that Amazon has awarded it to place into orbit a large percentage of that company’s Kuiper internet satellite constellation, assuming of course Blue Origin can deliver on schedule the many BE-4 engines that ULA will require.

This launch will also likely lead to the sale of ULA. » Read more

NASA: UAE to build airlock module for lunar station plus have astronaut fly there

9:20 am

According to a press release from NASA today, the United Arab Emirates (UAE) will build the airlock module for the Lunar Gateway space station plus have one astronaut fly a mission to the station after it is built.

Under a new implementing arrangement expanding their human spaceflight collaboration with NASA through Gateway, MBRSC will provide Gateway’s Crew and Science Airlock module, as well as a UAE astronaut to fly to the lunar space station on a future Artemis mission.

I strongly suspect that the UAE will mostly pay for this module to be built, hiring outside contractors from either the U.S. or Europe to do the work.

Canyons formed from the giant crack that splits Mars

Canyons formed by the giant crack that splits Mars
Click for original image.

Cool image time! The photo to the right, cropped, reduced, and sharpened to post here, was taken on September 22, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a complex of north-south trending canyons, with easternmost cliff about 400 feet high (though the full drop to the large canyon on its east is closer to 800 feet).

These canyons however have nothing to do with ice or water flow. They were formed by underground tectonic forces that pushed the ground upward, forced it to split and form cracks. Those cracks in turn produced these canyons. In some cases, such as the depression on top of the central ridge, the formation process probably occurred because fissures formed below ground, causing the surface to sag.

As always, the hiker in me wants to walk up the nose of that ridge and then along its western edge, with the western canyon on my left and that smaller depression on my right.

The larger context of this location is in itself even more spectacular.

SpaceX sues to have NLRB complaint dismissed

10:31 am

SpaceX yesterday filed a lawsuit in the federal courts to have the employee complaint filed by the National Labor Relations Board (NLRB) dismissed as a violation of the company’s fifth and seventh amendment rights as well as article II of the Constitution.

You can read SpaceX’s lawsuit here [pdf]. It specifically lists as defendants the board members of the NLRB, as well as the unnamed administrative judge who will run the NLRB’s case, once it begins.

The SpaceX lawsuit is interesting in that it challenges the very legal structure that has established the NLRB, stating that its actions are illegal because that structure forbids the President from having full control over its actions, as required by article II of the Constitution.

Whether this lawsuit succeeds is of course unknown, but its quick filing tells us that SpaceX was prepared for this NLRB action, even before it was filed. It also tells us that the company now recognizes the overall threat to it by the Biden administration, which appears to be trying to weaponize every agency in the federal government to destroy the company, and is prepared to fight long and hard against this abuse of power.

Japan’s XRISM X-ray space telescope, which launched in September, has now released first data and images.

One image showed the wide field view of the telescope’s Xtend imager, capable of viewing in X-rays an area of the sky 60% larger than the Moon. The second, shown to the right, provided a false color image of a supernova remnant in the Large Magellanic Cloud along with spectroscopy that data provided. According to the caption, “the spectrum reveals peaks associated with silicon, sulfur, argon, calcium, and iron.”

These pictures were produced during the telescope’s check-out period since launch. The mission, though Japanese-led, is being managed by NASA’s Goddard Space Flight Center, which is now accepting observation proposals for a full science schedule of observations to begin in the summer of this year.

Researchers propose method for removing toxic perchlorates from Martian water

9:55 am

Of the twelve research grants just awarded by NASA to develop a variety of new technologies for astronomy and future space exploration, one proposes a new method for removing the toxic perchlorates that are thought to exist in all Martian water.

What if we could make the perchlorates just vanish? This is the innovative solution we propose here, taking advantage of the reduction of chlorate and perchlorate to chloride and oxygen being thermodynamically favorable, if kinetically slow. This is the promise of our regenerative perchlorate reduction system, leveraging synthetic biology to take advantage of and improve upon natural perchlorate reducing bacteria.

These terrestrial microbes are not directly suitable for off-world use, but their key genes pcrAB and cld, which catalyze the reduction of perchlorates to chloride and oxygen, have been previously identified and well-studied. This proposed work exploits the prior work studying perchlorate-reducing bacteria by engineering this perchlorate reduction pathway into the spaceflight proven Bacillus subtilis strain 168, under the control of a robust, active promoter. This solution is highly sustainable and scalable, and unlike traditional water purification approaches, outright eliminates perchlorates rather than filtering them to dump somewhere nearby.

Essentially the researchers will try to engineer bacteria known to be able to survive space so that it carries genes from another microbe able of changing the perchlorate into chloride and oxygen.

This study as well as the other eleven are only in phase one of their contracts, with the award of later phases determined by their initial successes or failures.

Japan delays launch of Mars sample return mission due to problems with its H3 rocket

9:43 am

Japan’s space agency JAXA last week officially delayed the launch of its MMX Mars sample return mission, from later this year until the next Mars launch window in 2026.

A September 2024 launch would have seen MMX reach the Red Planet in August 2025 and return to Earth with around 0.35 oz (10 grams) of samples of the Mars moon Phobos in 2029. But the mission now must wait until the next Mars launch window opens in late 2026; its samples are slated to reach Earth in 2031.

The delay is because of JAXA’s ongoing problems getting its new H3 rocket off the ground. The first test launch last year failed, and though the next launch attempt is now scheduled for February, the agency decided it wanted more time to prove out the rocket before putting the Mars mission on it.

This decision once again highlights the overall failure of JAXA to produce for Japan a viable space effort. It is long past time for the Japanese government to take control from this agency, and allow the private sector to compete freely for business. Right now Japan’s continuing failures in space are downright embarrassing, compared to its Asian neighbors of China, India, and South Korea.
