Webb: Needles scattered near the center of the Milky Way

9:14 am

Needles in space
Click for original image.

Scientists today released a new false-color infrared image taken by the Webb Space Telescope of a region about 300 light years from the center of the Milky Way, dubbed Sagittarius-C. That picture is to the right, cropped, reduced and sharpened to post here. The blue or cyan regions are ionized hydrogen clouds, and with this image were revealed to be much more extensive than expected. The orange blob near the center is a densely packed cluster of protostars, the starlight blocked by the cloud of material.

The most interesting feature however are the needle-like structures within that ionized hydrogen, oriented in all directions in a manner that looks completely random. Though such needles have been seen previously, the data here is far more detailed, and might eventually help astronomers figure out what the heck these features are and what caused them.

SpaceX successfully launches Superheavy and Starship

6:57 am

Superheavy & Starship, on their way
Note how all 33 Superheavy engines are firing.

SpaceX this morning successfully launched its Superheavy/Starship heavy lift rocket into its test orbit.

The test flight achieved far more than the first test in April. First, during the entire flight of Superheavy all 33 Raptor-2 engines fired normally. None cut out prematurely. Then at very risky hot fire stage separation — where the second stage (Starship) ignited prior to separation from Superheavy — the correct number of engines shut down, Starship’s engines fired, and Superheavy successfully separated and began its maneuvers for a soft splashdown in the Gulf of Mexico.

At that point mission controllers issued the self-destruct command to destroy Superheavy. Though it appeared that the stage was struggling to flip for its controlled return to Earth, it is also very likely that mission controllers wanted to test that flight termination system after its not perfect performance on the first test flight. Then, the self-destruct command did not activate the instant the command was given, being delayed by about 40 seconds. This time it appeared it worked as planned.

SpaceX launches 23 Starlink satellites

10:15 pm

While everyone is focused on the Starship/Superheavy launch scheduled for tomorrow at 7 am (Central) at Boca Chica, SpaceX tonight launched another 23 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage successfully completed it eleventh flight, landing on a drone ship in the Atlantic.

The leaders in the 2023 launch race:

84 SpaceX
52 China
14 Russia
7 Rocket Lab
7 India

American private enterprise still leads China 96 to 52 in successful launches, and the entire world combined 96 to 81. SpaceX by itself is now leads the rest of the world (excluding American companies) 84 to 81.

The southernmost extent of Mars’ youngest lava flood event

The southernmost edge of Mars' youngest lava event
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on August 24, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

Labeled “flow margin in Elysium Planitia,” it shows the very edge of what scientists believe was the most recent large lava event on Mars, dubbed the Athabasca Valles, that is thought to have occurred only 600 million years ago. In only a matter of weeks the fast flowing lava covered a region about the size of Great Britain. What we see here is the southernmost edge of that flow, with the smooth terrain on the west an older lava flood plain, covered by the new flood lava from Athabasca on the east.

The polygon cracks likely indicate cracks that formed during the hardening process (like the polygon cracks in drying mud). Hot lava then pushed up from below to form the ridges. It is also possible the ridges are what scientists call “wrinkle ridges,” formed when material shrinks during the drying process.

Salt glaciers on Mercury?

10:55 am

From Figure A1 of paper
From Figure A1 of paper.

Based on a new analysis of data from the Messenger spacecrat that orbited Mercury from 2011 to 2015, scientists today posited the possibility that salt glaciers exist on Mercury and have reshaped its terrain in manner vaguely comparable to what Mars Reconnaissance Orbiter (MRO) has found on Mars.

You can read the paper here [pdf]. The image to the right, enhanced by the scientists to bring out the faint blue in the hollows, is remarkably reminiscent of the hollows and scallop terrain found in many places in the high Martian latitudes. From its conclusion:

Detecting widespread elemental volatile surface compositions, ubiquitous sublimation hollows, and extensive chaotic terrains has significantly reshaped our perception of Mercury’s geological past. These observations collectively point to the presence of volatile-rich strata spanning several kilometers in depth and likely formed before the [Late Heavy Bombardment] (∼3.8 billion years ago). This notion challenges the conventional view of a volatile-depleted Mercurian crust.

The morphologies within Mercury’s Raditladi basin bear a striking morphologic resemblance to glaciers on Earth and Mars, suggesting their origin from an impact-exposed [volatile-rich layer], likely containing halite. Our numerical simulations show that the unique rheological properties of halite, including the high thermal sensitivity of its viscosity, reinforce this hypothesis. These glacier-like features occur beyond the chaotic terrain boundaries, indicating a potentially global yet concealed, volatile-rich upper stratigraphy. We posit that the exposure of these volatile-rich materials, instigated by impact events, could have been instrumental in the formation and evolution of hollow features, signifying a complex geodynamic history of volatile migration and redistribution, essentially interconnecting some of the oldest and youngest stratigraphic materials on the planet.

The scientists do not have enough information as yet to determine if these glaciers are still active or not. Moreover, the theorized layer of volatile material near the surface remains unconfirmed, requiring in situ investigation to determine its existence with certainty. Like Mars, if it exists it likely only does so in the high latitudes.

Researchers confirm it was a Chinese rocket stage that impacted Moon in 2022

9:35 am

Impact, before and after
The crash site is the double crater in the
lower image.

Researchers have now confirmed that the unknown rocket stage that impacted the Moon in 2022 was from a Chinese rocket, a Long March 3B that launched China’s Chang’e-5 lunar sample return mission in November 2020.

“In this paper, we present a trajectory and spectroscopic analysis using ground-based telescope observations to show conclusively that WE0913A is the Long March 3C rocket body (R/B) from the Chang’e 5-T1 mission,” the researchers, led by Tanner Campbell, a doctoral student in the UA’s Department of Aerospace and Mechanical Engineering, wrote in a study that came out Thursday (Nov. 16) in the Planetary Science Journal. These two lines of evidence — how the object was moving and what it was made of — leave little doubt about WE0913A’s provenance, Campbell and his colleagues report.

The data, combined with the unusual double crater caused by the impact, also suggests that this stage had additional unknown equipment at its top, matching the mass of its engines at the bottom. Since the Chinese continue to deny it was their stage and have said nothing about it, we have no idea what that extra equipment might have been.

German rocket startup signs deal with Norwegian spaceport

9:23 am

Map of northern European spaceports

The German rocket startup Isar Aerospace has signed a deal to provide the Andoya spaceport in the north of Norway with a new flight tracking and safety system, to be used by all launches including Isar’s own Spectrum rocket.

The purpose of the autonomous flight tracking system is to precisely and reliably keeping track of the Spectrum launch vehicle’s position, speed and direction of travel as it ascends to orbit, which is important to guarantee Andøya Spaceport’s flight safety requirements. The objective is to further evaluate the use of the system in enabling automated flight termination functionality for launches by Andøya Spaceport’s ground system, autonomously triggering an abort of the mission if ever operational parameters of the launch vehicle are out of bounds.

This announcement today illustrates the rising competition between German rocket startups and European spaceports. Yesterday the Saxavord spaceport in Scotland and another German rocket startup, HyImpulse, announced their own launch deal. Today’s announcement is the response from Andoya and Isar.

Today’s announcement also increases the pressure in the UK’s Civil Aviation Authority (CAA) to get its regulatory act together. Andoya is positioning itself as a good alternative to the two new British spaceports in Scotland, as shown by the red dots on the map above, should red tape in the UK slow launches there.

House committee delays vote on commercial space bill due to new White House proposal

8:59 am

Because of the sudden announcement by the White House of its own version of a new commercial regulatory space bill, the House Science committee was forced to delay the voting on November 15, 2023 of its own new commercial space bill, put forth by Republicans.

The committee met Nov. 15 to mark up the Commercial Space Act of 2023 and one other bill. At the end of the markup, lasting more than three and a half hours including a recess, the committee’s chairman, Frank Lucas (R-Okla.) said the committee would delay votes to advance both bills until after the Thanksgiving break because of votes on the House floor and “and the nature of additional information that has become available to us.”

The latter comment appeared to be a reference to a legislative proposal released by the White House’s National Space Council less than an hour before the markup regarding a mission authorization concept for new space activities. That proposal would establish a system where both the Commerce Department and the Transportation Department would oversee activities not regulated today, based on the type of activity.

The House bill, introduced Nov. 2 by Lucas and space subcommittee chairman Rep. Brian Babin (R-Texas), would create its own mission authorization system at the Commerce Department. It would also direct Commerce to hand over responsibility for a civil space traffic coordination system to a consortium led by an academic or nonprofit organization, rather than keeping it within the Office of Space Commerce as currently planned. Lucas, in his opening remarks, said he was aware of the new White House proposal but has reservations about it. “These proposals, I fear, simply go in the wrong direction and hurt rather than support America’s space industry,” he said.

Both bills were aimed at realigning the regulatory regime governing private space activities. The House bill’s final form apparently had been written with a lot of industry input. The White House bill, supported by Democrats, appears designed instead to clamp down on commercial space by allowing the federal bureaucracy to regulate everything.

Both bills unfortunately give too much power to the federal government, though the Republican bill at least tries to shift some of that power to the private sector, where it belongs.

One of the main reasons we have had a rennaisance in commercial space in the past decade is that there has been little regulation. The private sector has been left to regulate itself, and it has generally done so very successfully because of the invisible hand of free market forces. Build things right and the world beats a path to your door. Do it badly and no regulation is needed, you go out of business.

Modern Americans no longer trust these fundamentals of freedom and capitalism, and so we have a rush by government to establish “rules,” none of which will really accomplish anything but slow development and innovation and squelch this emerging industry.

Sierra Space shakes up its staffing

8:44 am

Sierra Space yesterday did a major staffing shake up, laying off 165 workers while shifting 150 with secruity clearances from its parent company Sierra Nevada.

Sierra Space this week shipped the first Dream Chaser, named Tenacity, for pre-launch testing at NASA’s Armstrong facility in Ohio. The layoffs began soon after, the Sierra Space spokesperson said, noting the company conducted a surge in hiring this year to complete work on the Tenacity spacecraft.

With Tenacity shipped, Sierra Space’s spokesperson said the company is realigning to focus on the operations phase of Dream Chaser’s first mission, as well as on classified national security work. The latter part of Sierra Space’s realignment includes adding nearly 150 employees with security clearances from Sierra Nevada Corp., the aerospace and defense contractor owned by Fatih and Eren Ozmen, which the space company was spun out of two years ago. Sierra Space’s spokesperson said the company is creating a national security space team to work on several classified contracts.

This shift suggests that at least in the short run, Sierra is putting more focus on future military contracts rather than its civilian manned space projects like its LIFE space module (for the Orbital Reef space station) and future manner versions of its Dream Chaser mini-shuttle. I wonder if the company is having more internal doubts about Orbital Reef and its main partner, Blue Origin. Unlike the stations being built by Axiom and Voyager Space, which have already garnered contracts from both national and international customers, Orbital Reef has not done the same. There could be great doubts in the space community it will be built because of Blue Origin’s absymal record for building anything.

Amazon’s first two Kuiper satellites in orbit worked exactly as planned

2:55 pm

Amazon announced today that its first two Kuiper satellites, launched into orbit by ULA’s Atlas-5 rocket on October 6, 2023, have worked exactly as planned, thus allowing the company to begin building operational satellites.

With the prototypes’ testing in space now complete, Badyal said Amazon plans to begin building the first production Kuiper satellites in December and launch the first satellites for its network in the “latter part of the first half” of 2024. Badyal emphasized that Amazon wasn’t sure what performance to expect from the prototype satellites, since “you don’t know how well it’s going to work in space.”

“They’re working brilliantly,” Badyal said.

The need of Amazon to start launching lots of satellites next year — in order to meet its FCC license requirements to put half of its 3,000+ constellation in orbit by 2026 — puts great pressure on ULA, Blue Origin, and Arianespace to get their new but as yet unlaunchd rockets operating. All three have big launch contracts with Amazon, but none presently appear to have the capability to meet the demands of those contracts.

Jupiter’s Great Red Spot continues to shrink, possibly to its smallest size ever measured

2:27 pm

Jupiter, as seen by Hubble in 2020

Click for full image.

Long term data from numerous observatories shows that the Great Red Spot on Jupiter, the largest and longest lasting storm in the solar system, has been continuously shrinking for decades, and appears approaching this year its smallest size ever measured.

Despite so many factors working to keep it “alive” the Spot may be in need of life support. It’s been shrinking for decades. In 2012 the rate of shrinkage abruptly accelerated, something many amateur observers have commented on since that time. Several years later, while still shrinking in diameter, it expanded in latitude becoming more circular. Now it’s narrowed again and continues to diminish in both axes. This observing season I’ve been struck by the Spot’s unusually small size. That, along with its pale pink color and turbulent environment, have made it less obvious than ever.

…Using the WinJUPOS program and one of his recent high-resolution images, Peach measured the Great Red Spot’s diameter on November 6, 2023, at 12,500 kilometers or about 7,770 miles across. If confirmed it would make this season’s GRS not only smaller than the Earth (12,756 kilometers or 7,926 miles across) but the smallest size in observational history. A British Astronomical Association Jupiter section bulletin on October 30th described it as “the smallest it has ever been.” That’s a far cry from the late 1800s when the Spot ballooned to 41,000 kilometers (25,500 miles) — big enough to swallow three Earths with room to spare. Now it can barely contain one!

No one knows if this shrinkage is merely a normal long term fluctuation, or a sign that this many-centuries-old storm is finally dissippating. When it comes to the solar system’s gas giants, their size and long orbits make any firm conclusion difficult in only a few centuries of observation. To understand them properly will likely require thousands of years of observations, covering many orbits and seasons.

Saxavord spaceport gets launch deal from German rocket startup

2:07 pm

The Saxavord spaceport, one of two being built in Scotland, has signed a launch deal from the German rocket startup Hy-Impulse, with two suborbital test launches scheduled for next year and an orbital launch targeting 2025.

HyImpulse, a launch services provider and DLR spinoff based in Baden-Württemberg, Germany, is currently gearing up for its inaugural suborbital launch early next year from Australia. It will however look to conduct two suborbital launches from SaxaVord Spaceport, located in Scotland’s Shetland Islands, from August 2024 onwards. HyImpulse has already secured an Air Navigation Order (ANO) license from the UK’s Civil Aviation Authority for one launch.

These will be followed by first orbital launches from late 2025 onwards. The plan envisions rising to full commercial operations by 2030.

All this assumes that the UK’s Civil Aviation Authority (CAA) can issue the launch licenses in time. After all it only six to ten months to approve those suborbital launches, and almost two years to approve the orbital launch. So far the CAA has proven unable to approve anything within even those long time frames.

Biden White House proposes major expansion of the regulations governing commercial space

9:23 am

We’re here to help you! The Biden White House yesterday proposed a major expansion of the regulations that govern commercial space, with the changes aimed at splitting all regulation within the Transportaion and Commerce Departments, but expand the regulations to so as to increase the power of the government over all future activitives, from rockets to spacecraft to space stations.

According to the White House’s statement [pdf]:

Specifically, this proposal would amend 51 U.S.C. 50902 to define a “human space flight vehicle” as a vehicle, including a launch vehicle or reentry vehicle, habitat, or other object, built to operate in suborbital trajectory or outer space, including on a celestial body, with a human being on board. A license would then be required for a citizen of the United States to operate a human space flight vehicle in outer space. (51 U.S.C. 50904).

DOT would authorize the operation of a human space flight vehicle consistent with public health and safety, safety of property, space sustainability, international obligations of the United States, and national security, foreign policy, and other national interests of the United States. (51 U.S.C. 50905). This proposal adds “space sustainability” and “other national interests” to DOT’s current authority. Including “space sustainability” would allow DOT to include debris mitigation and require measures to protect the sustainable use of outer space in their regulations, to include the mitigation and remediation of orbital debris and consideration of impacts to the space operational environment. [emphasis mine]

Essentially, these new rules — purposely written to be vague — will allow the government to forbid any activity in space by private citizens it chooses to forbid. No private space station could launch without government approval, which will also include the government’s own determination that the station will be operatied safely. Once launched, the vagueness of these regulations will soon allow mission creep so that every new activity in space will soon fall under its review.

Since no one in the government is qualified to supervise things like this, in the end politics and the abuse of power will be the rule.

Moreover, by what constitutional right does the federal government have to supervise the work of all space companies, in all things? It doesn’t have that right, and in fact the Constitution was written expressly to forbid it from attempting such a thing. The Constitution however is nothing more than fish wrap in modern America.

Note that most other news reports on this proposal are making it sound as nothing more than a simple revision of the law to better organize the regulatory system. The assumption is always that the government is all-knowing and all-seeing, and has the ability to act as school teacher for everyone else.

Initially we can expect these regulations will be followed with good faith, but such things never last. Given time they will end up squelching freedom in space and the entire American effort to colonize the solar system. And should any American colony become reasonably self-sufficient under these rules (something not likely), the rules guarantee that they will revolt from American rule as quickly as possible.

At this moment this proposal is simply that. Congress needs to review it and decide if it wishes to do as the Biden White House proposes. Though it is unlikely it will pass as written, it is also likely that our present Congress will simply reword it to accept this expansion of power, in some manner.

China launches ocean observation satellite

8:52 am

China today successfully launched what it claimed was the first of a new generation of ocean observation satellites, its Long March 2C rocket lifting off from its Jiuquan spaceport in northwest China.

No word on where the rocket’s lower stages, which use toxic hypergolic fuels, crashed inside China.

The leaders in the 2023 launch race:

83 SpaceX
52 China
14 Russia
7 Rocket Lab
7 India

American private enterprise still leads China 95 to 52 in successful launches, and the entire world combined 95 to 81. SpaceX by itself is still leads the rest of the world (excluding American companies) 83 to 81.

FAA and Fish & Wildlife approve further launches of Starship/Superheav at Boca Chica

UPDATE: The FAA has now issued the launch licence [pdf]. Note it adds that the FAA and Fish & Wildlife have imposed new requirements (as noted in the announcements below) on SpaceX on this and future launches, all of which will have to be reviewed after each launch.

Original post:
————————-
Both the FAA and the Fish & Wildlife department of the Interior Departiment today released their completed investigations of the environmental impacts created by the first test launch of SpaceX’s Starship/Superheavy rocket in April 2023, and (not surprisingly) concluded that the launch did no harm, and that a second launch can be allowed.

The FAA report can be found here [pdf]. The Fish & Wildlife report can be found here [pdf]. Both essentially come to the same conclusion — though in minute detail — that Fish and Wildlife had determined in April 2023, only a week after that first test launch.

No debris was found on lands belonging to the refuge itself, but the agency said debris was spread out over 385 acres belonging to SpaceX and Boca Chica State Park. A fire covering 3.5 acres also started south of the pad on state park land, but the Fish and Wildlife Service didn’t state what caused the fire or how long it burned.

There was no evidence, though, that the launch and debris it created harmed wildlife. “At this time, no dead birds or wildlife have been found on refuge-owned or managed lands,” the agency said. [emphasis mine]

In other words, the investigation for the past seven months was merely to complete the paperwork, in detail, for these obvious conclusions then.

As part of the FAA action today, it also issued range restrictions for a November 17, 2023 test launch at Boca Chica. Though there is no word yet of the issuance of an actual launch license, it appears one will be issued, and SpaceX is prepared for launch that day, with a 2.5 hourlong launch window, opening at 7 am (Central). SpaceX has already announced that its live stream will begin about 30 minutes before launch, at this link as well as on X.

Lava/ice eruptions on Mars

Lava/ice eruptions on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on August 1, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled by the science team as showing “possible lava-ice interaction,” the photo features some pimply-looking mounds that, though round like craters, sit above the surrounding landscape like small volcanoes.

That these are likely not ancient pedestal impact craters that now sit higher because their material is packed and can resist erosion is illustrated by the bridge-like mound in the lower right. This mound was likely once solid, but its north and south sections have disappeared, either by erosion or sublimation. If formed by an impact the mound would have had a depression in its top center, and would have only eroded outside the rim.

Japan to spend $6.6 billion over ten years to develop its space industry

9:19 am

The Japanese government has created a new $6.6 billion fund that it will provide to its space agency JAXA, spread out over the next ten years, to help develop the country’s commercial space industry.

The very short article at the link provides little additional information. For example, will JAXA be required to act merely as a customer, buying services from competing private companies, or will it be allowed to use this money to create its own projects that it designs, builds, and owns?

The difference is fundamental. Presently JAXA functions like NASA had for decades, partnering with only a handful of big space companies (Mitsubishi for example) to build its own government rockets and spaceships. The results have been comparable to NASA prior to 2010: Little gets built and whatever is built is overbudget and far behind schedule.

Since NASA accepted the idea of capitalism in space, where it no longer builds or owns much but relies on private enterprise to get it done, things have moved fast. Similarly, India and China have followed suit, and both are getting similar good results.

The unanswered question from this story is whether Japan has finally taken the leap to do it as well. Making this transition can be politically difficult, because the space agencies and big space contractors fight to protect their turf. It is not clear if the Japanese government is willing to fight that battle.

If it doesn’t, however, Japan will continue to be a backwater in space, like Russia,as the rest of the world’s space-faring nations increasingly turn to private enterprise, competition, and (most of all) freedom to get results.

Scientists: More evidence cosmic rays come from nearby supernova remnants

9:07 am

The uncertainty of science: According to high energy data from an instrument on ISS, astronomers found more evidence that the cosmic rays that enter our solar system likely come from nearby supernova remnants.

Current theory posits that the aftermath of supernovae (exploding stars), called supernova remnants, produce these high energy electrons, which are a specific type of cosmic ray. Electrons lose energy very quickly after leaving their source, so the rare electrons arriving at CALET with high energy are believed to originate in supernova remnants that are relatively nearby (on a cosmic scale), Cannady explains.

The study’s results are “a strong indicator that the paradigm that we have for understanding these high-energy electrons—that they come from supernova remnants and that they are accelerated the way that we think they are—is correct,” Cannady says. The findings “give insight into what’s going on in these supernova remnants, and offer a way to understand the galaxy and these sources in the galaxy better.”

The results however do not prove this. Nor do they eliminate the possibility that cosmic rays might also come from other sources outside our galaxy. At present the data is simply too uncertain.

Intuitive Machines will attempt to launch 3 lunar landing missions in 2024

8:52 am

South Pole of Moon with landing sites

According to the company’s CEO, Intuitive Machines is pushing to fly two more Nova-C lunar landing missions next year after its first is launched by SpaceX on January 12th and hopefully lands successfully near the Moon’s south pole on January 19th.

Intuitive Machines is working on two more Nova-C landers for its IM-2 and IM-3 missions, also carrying NASA CLPS payloads. The company has not announced launch dates for those missions, but Altemus said he hoped both could take place by the end of 2024.

“We are planning three missions in 2024,” he said, which will depend in part on NASA’s requirements as well as orbital dynamics. Landings at the south polar region of the moon, the target for IM-2, are linked to “seasons” where lighting conditions are optimal for lander operations. IM-3, he said, would happen “a few months” after IM-2.

Though Nova-C will launch after Astrobotic’s Peregrine lander (launching on ULA’s Vulcan rocket), it will get to the Moon quickly, and will attempt its landing first. If successfully it will therefore be the first private payload to do so.

The company’s ambitions for 2024 are laudable, but depend so entirely on everything going perfectly it will not be surprising if they do not pan out. Nor will it reflect badly on the company if just one mission flies in 2024. Landing a robot on another world is hard. For private companies to do it is harder.

ESA firms up space station partnership with Voyager Space

8:38 am

The European Space Agency (ESA) and the American company Voyager Space last week signed an agreement making Voyager’s Starlab space station Europe’s main space station destination, replacing ISS.

Starlab will fulfill that role, at least partially, in the future for the space agencies of individual ESA member states. It’s expected to launch as soon as 2028, with operations set to start in 2029. This will include access for astronaut missions and to conduct research as well as providing opportunities for commercial business development. Starlab is also set to provide a complete “end-to-end” system in low-Earth orbit to which European crews and cargo will journey.

This European deal became more likely when Airbus joined the partnership of Voyager and Lockheed Martin in January 2023. It is also probably why Northrop Grumman in October 2023 abandoned its own space station project and joined this one instead. ESA is a big customer, most likely to guarantee the most profits.

What makes this deal different than ISS is that the station will not be owned by this large government customer. The companies building Starlab — led by Voyager — will be free to sell its services to anyone who wishes to use it. This deal also means that NASA and ESA will be going separate ways after ISS, no longer partnering on a station.

The caldera wall of a Martian giant volcano

The caldera wall of Pavonis Mons
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and enhanced to post here, was taken on June 8, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the top half of the northwestern interior wall of the central caldera of Pavonis Mons, the center volcano in the string of three giant volcanos found in Mars’ equatorial regions.

The elevation change from the top to the bottom of this picture is about 7,000 feet, though this covers only half the distance down to the floor of the caldera. The picture was taken as part of a survey of this caldera wall.

Volcanic activity here is thought to have ended more than a billion years ago. Thus we are looking at relatively old terrain that has had many eons to be reshaped since the last eruption.

NASA “pauses” Mars Sample Return mission

9:11 am

Perseverance’s first set of core samples,
placed on the floor of Jezero Crater

Faced with a strong threat of major budget cuts from the Senate, NASA has decided to “pause” the Mars Sample Return mission (MSR) by ramping back some work to consider major changes to the project.

We brought Steve [Thibault] downtown to be the chief engineer in the Headquarters MSR program office … leading a team that consists of all the implementing centers and our European colleagues to stand back and take a look at the architecture with a fresh set of eyes and figure out not only just how to improve our technical margins and make the mission more robust, but also to see if there are ways to implement it in ways to potentially save costs. We’re also going off and listening to industry and seeing what ideas they have.

While the House had approved NASA’s budget request that exceeded $1 billion to complete the mission (more than double its original price tag), the Senate responded by only allocating one quarter of that, demanding NASA come up with a plan that would match its original budget number. This Senate pressure was enhanced by an independent review that harshly criticized the present design of the project, which involves three NASA centers, European participation, and multiple American companies, all building different components that must all interact perfectly.

Musk: Government approval for 2nd Starship/Superheavy launch expected before Friday

8:35 am

According to a tweet today by Elon Musk, he has been informed that the federal government will give its blessing for SpaceX to conduct the second Starship/Superheavy test launch from Boca Chica in time for a Friday November 17, 2023 launch.

The launch window opens at 7 am (Central) and lasts until 11:20 am.

Let us all now bow our heads to our lords and saviors at the FAA and Fish and Wildlife for finally deciding to allow this once-free American to simply do something the government was once forbidden from blocking. The worst part is that the fundamental law that forbids such government interference (its called the Constitution and the Bill of Rights) has not been officially repealed, merely morphed into nothing more than fish wrap while everyone decided to look the other way.

Be warned: Even if by some miracle this second test launch goes perfectly, these government agencies are still not going to allow a quick turn-around for a third launch. No, they will put SpaceX through the same investigatory grind, eating up months. And if the more likely scenario occurs, and the launch does not go perfectly, I guarantee the grind will go on longer.

Sovereign power now resides within Washington, not the people of the United States. The proof is how so many of those people now consider this situation normal and expected.

Curiosity looks back at Gale Crater one last time before month-long communications break

Looking back at Gale Crater

Overview map

Though the view has not changed much since early October, when I last posted a Curiosity navigation image looking out across Gale Crater from the present heights of Mount Sharp, today’s image above, taken on November 8, 2023, sol 4001 since the rover landed on Mars, signals the beginning of the monthlong solar conjunction, when all communications with Mars is blocked because the Sun has moved between the Earth and the Red Planet.

Solar conjunction occurs every two years, with this being the sixth conjunction experienced by Curiosity. It officially began on November 6th and is expected to end around November 29th. The picture above however was obtained two days into that conjuction, and is unusual in that it does not have the large drop-outs now seen in many other images taken then, both from Curiosity and Perseverance. We should expect there to be very few additional images before the end of November.

The blue dot in the overview map to the right shows Curiosity’s present position, with the yellow lines indicating roughly the area covered by the picture above. The crater rim is about 20 to 25 miles away, with the peak of Mount Sharp about the same distance away in the opposite direction. The rover has climbed about 2,500 feet, but it still sits about 13,000 feet below the mountain’s peak. Though the photo encompasses Curiosity’s entire route since landing, most of it is out of sight, the lower flanks of Mount Sharp blocking our view.

Spanish court indicts two high-altitude balloon companies for stealing from third

9:16 am

In a legal battle between the three Spanish high-altitude balloon tourist companies (Zero-2, Halo, and Eos-X), a court in Spain has indicted the latter two for stealing trade secrets from the first.

The case stems from Zero 2 Infinity’s allegations that the people hired to raise money for its space tourism business established two competing firms based on Zero 2 Infinity’s intellectual property.

After asking for extensive documentation to share with potential investors, some of the individuals indicted “changed the logo in the presentations and managed to raise 1 million euros for a company that was just a website with some” computer generated imagery, Jose Mariano Lopez-Urdiales, Zero 2 Infinity founder and CEO, told SpaceNews. “They thought they could do that because Zero 2 Infinity was in financial distress, in part because we were expecting that 1 million euros to arrive.”

…The law in question carries potential penalties “of imprisonment from three to five years” if the secrets in question were “disseminated, revealed, or transferred to third parties” in addition to fines, Spanish attorney Leonardo López Marcos, co-founder of the International Legal Center for Space Sustainability, said by email.

One of the companies, Halo, apparently used the fund-raisers as a go-between so that it never had any direct links to the original company, Zero-2. Of the three companies, Halo has now done the most test flights. Whether this ruling will force it to shut down remains unclear.
