  • Kuiper official urges governments to regulate the methods used by satellite makers to maneuver their satellites

    • I like Jay’s comment: “How many satellites does Kuiper have again? Zero. Damn arm-chair satellite companies!” The timing of this statement, a day after the WEF issued its proposed government guidelines for de-orbiting satellites, suggests Amazon supports that effort, but has a different approach as to how those rules should be implemented.

    In other words, Amazon wants to dictate how others build their satellites. Or make it illegal for them to do so as they wish. Seems a great plan for eliminating one’s competition.

Tomorrow’s final launch of Europe’s Ariane-5 rocket delayed indefinitely

2:01 pm

Arianespace officials today cancelled tomorrow’s final launch of its Ariane-5 rocket — supposedly to be replaced by the not-yet-flown Ariane-6, citing issues with “three pyrotechnical transmission lines that are associated with the Ariane 5’s solid rocket boosters.”

No new launch date has been set. There is the possibility that to resolve this issue the rocket will have to be rolled back to its assembly building and destacked. If so, the launch will be delayed months.

At the moment, Europe has only managed one launch in 2023, a far cry from the seven to twelve launches it used to do annually, before SpaceX came along and offered a cheaper rocket that could launch more frequently and quicker.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon, any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Some real pushback: Former Starbucks employee, fired to give Starbucks a white scapegoat, wins $25 million in lawsuit

1:37 pm

Enthusiastically supports racial discrimiation
Punished enthusiastically for enthusiastically
supporting racial discrimination

Bring a gun to a knife fight: Shannon Phillips, a former Starbucks employee for thirteen years who was fired from the company following a racial incident at one of its stores, has been awarded back pay and $25.6 million in compensatory and punitive damages by a jury, who ruled she was fired simply because she was white and Starbucks needed a scapegoat.

The controversy began when the staff at a Starbucks store called the police on two blacks sitting in the store.

Rashon Nelson and his friend Donte Robinson were arrested at the Philly Starbucks in April 2018 after an employee called 911 to say they weren’t paying customers and had refused to leave. The men, who said they had been simply sitting at a table waiting for a potential real estate business partner to arrive, were arrested for trespassing.

In response to the widespread protests that followed, Starbucks temporarily shut its 8,000 locations nationwide in order to give its employees “anti-bias training,” while coming to an out-of-court settlement with the two men, whereby they each were paid a symbolic $1 but the company set up a $200,000 program to help young entrepreneurs.

The company also decided to fire Phillips, even though she was not at the store when the incident occurred. That firing was because she had objected to the company’s order for her to suspend a white manager who had had no connection to the incident at all.

Cape Canaveral, version 2.0

Falcon 9 first stage hauled back to the cape after launch
Falcon 9 first stage hauled back to the cape after launch

Last week BtB’s intrepid stringer Jay was unable to send me any “Quick Space links” because he was working at Cape Canaveral at the Kennedy Space Center, involved in a project involving, as he noted, “infrastructure,” giving him only a limited access to the center.

He did however have time to drive around and take pictures. For example, we have the picture on the right. On his way to lunch on his second day there he “had to pull over for a semi carrying something large. At first I thought it was a fuel tank, but it was the first stage of a Falcon-9 that lifted off on June 4th.”

This picture alone illustrates how things have changed at Kennedy since the retirement of the shuttle in 2011. Then, local officials and NASA managers all thought the sky was falling in, and that the economy of Cape Canaveral was about to die forever with that retirement.

Instead, it is now entirely routine for a private rocket company to drive its used first stages back and forth in between launches. Cape Canaveral hasn’t died, it has been reborn.

More pictures by Jay are below, all of which illustrate the resurgence of space activity that private enterprise is bringing to America’s first spaceport. To quote Jay,

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

House proposed cuts pose no threat to NASA, despite the screams of agony

10:14 am

Proposed Republican budget cuts
Proposed Republican budget changes

Before even beginning this story, it is critical for my readers to understand that the worst any of these possible cuts could do to NASA’s budget in 2024 would be to bring it back to budgetary levels from most of the last decade, levels that hardly crippled the agency in the slightest.

The graph to the right, posted initially by Roll Call, outlines in detail the required cuts the Republicans in the House are demanding in the federal budget for the 2024 fiscal year. The percentages in the last column list the amount each of these twelve appropriation subcommittees must cut from their area of focus. NASA is part of the Commerce-Justice-Science category, which requires a total cut of 28.8%.

NASA’s budget in 2023 was $25.4 billion. If the House imposes that percentage cut to NASA, it would lower its 2024 budget to about $18 billion.

O my! We are all going to starve!

Taiwan company issues letter of intent to build cubesat facility in California city

9:27 am

The city of Paso Robles in California has now received an official letter of intent from the Taiwan cubesat company Gran Systems, describing its desire to build spaceport there.

The CEO of Gran Systems recently toured the proposed Paso Robles Spaceport and tech corridor area and met with Paso Robles Airport Manager Mark Scandalis to discuss opportunities for establishing its California facility in Paso Robles.

Though the news article refers to this as a “spaceport,” I don’t think this has anything to do with launching rockets. Instead, this spaceport is part of Paso Robles’ effort to establish an industrial park at its airport, including space companies such as satellite builders, and Gran Systems has decided to rent space there, probably to widen its market in the U.S.

Scientists detect evidence of phosphorus coming from the interior of Enceladus

9:13 am

Using archival data from the Cassini orbiter, scientists have now detected the first evidence of phosphorus – a key element in the development of life on Earth – coming from the interior of the Saturn moon Enceladus.

The small moon is known to possess a subsurface ocean, and water from that ocean erupts through cracks in Enceladus’ icy crust as geysers at its south pole, creating a plume. The plume then feeds Saturn’s E ring (a faint ring outside of the brighter main rings) with icy particles.

During its mission at the gas giant from 2004 to 2017, Cassini flew through the plume and E ring numerous times. Scientists found that Enceladus’ ice grains contain a rich array of minerals and organic compounds – including the ingredients for amino acids – associated with life as we know it.

Phosphorus, the least abundant of the essential elements necessary for biological processes, hadn’t been detected until now. The element is a building block for DNA, which forms chromosomes and carries genetic information, and is present in the bones of mammals, cell membranes, and ocean-dwelling plankton. Phosphorus is also a fundamental part of energy-carrying molecules present in all life on Earth. Life wouldn’t be possible without it.

“We previously found that Enceladus’ ocean is rich in a variety of organic compounds,” said Frank Postberg, a planetary scientist at Freie Universität Berlin, Germany, who led the new study, published on Wednesday, June 14, in the journal Nature. “But now, this new result reveals the clear chemical signature of substantial amounts of phosphorus salts inside icy particles ejected into space by the small moon’s plume. It’s the first time this essential element has been discovered in an ocean beyond Earth.”

You can read the paper here. It is very important to emphasize that though phosphorus is essential for life, life in the underground ocean of Enceladus has not been discovered. The scientists have merely found evidence of this specific ingredient needed for life, suggesting that these ingredients are common in our solar system. Going from a list of ingredients to a finished dish one can eat is something else entirely.

Arianespace signs deal with Spanish rocket startup PLD

8:58 am

Following up with its agreement with the UK rocket startup Orbex, Arianespace yesterday also signed a deal with the Spanish rocket startup PLD to study using that company’s as-yet-unflown Miura-5 rocket.

Like the Orbex deal, this agreement makes it possible for Arianespace to arrange launches using PLD’s rocket. It also tells us that Arianespace and the European Space Agency are shifting from designing and building their own rockets — a process that has failed to produce any profit and had presently left Europe with no launch capability — to acting simply as a customer buying that capability from independent competing private companies.

For this to work however both Orbex and PLD will have to get their rockets off the ground.

China launches 41 satellites on single launch, a record for that country

8:49 am

China today successfully used its Long March 2D rocket to place 41 satellites in orbit, a new record for that country, lifting off from its interior Taiyuan spaceport in north China.

No word on where the rocket’s first stage crashed within China, or whether it landed near any habitable areas. The Chinese state-run press also provided no information about any of those 41 satellites.

The leaders in the 2023 launch race:

40 SpaceX
23 China
8 Russia
5 Rocket Lab

American private enterprise still leads China 45 to 23 in the national rankings, and the entire world combined 45 to 39, with SpaceX by itself still leading the rest of the world, excluding other American companies, 40 to 39.

  • Diagram from ULA outlining the pattern of decay for orbital debris, depending on orbit

    • This diagram was posted in connection with a proposal from ULA’s CEO, Tori Bruno, suggesting a system similar to carbon credits to eliminate space junk. Bruno also suggests the U.S. should “kickstart” this program. The timing, the same day the WEF released its own space junk guidelines, suggests he is all-in on strong international regulation, along with the kind of scams (such as carbon credits) that this regulation always goes hand-in-hand with. It also suggests he wants to use that regulation to beat down his competitors, since on the open market ULA is failing miserably at this task.

Drainage channel between two Martian hollows

Drainage channel between two Martian hollows
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on April 28, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Dubbed a “terrain sample” by the camera team, it was likely taken not as part of any specific research project but to fill a gap in the camera’s schedule so as to maintain that camera’s proper temperature. When they have to do this, they try to pick interesting targets, though there is no guarantee the result will be very interesting.

In this case the camera snapped what appears to be a drainage channel between two deeper hollows. The channel sits about 100 feet above the western hollow and 260 feet above the eastern hollow. This makes some sense, as the overall drainage in this region is going from the west to the east, and then to the north.

Astronomers detect vaporized elements in atmosphere of hot Jupiter-sized exoplanet

8:23 am

Using the Gemini telescope in Hawaii, astronomers have detected several elements in atmosphere of hot Jupiter-sized exoplanet, dubbed WASP-76b, that would normally be found in rocks, but here are vaporized because the exoplanet orbits so close to its star.

In 2020 and 2021, using Gemini North’s MAROON-X (a new instrument specially designed to detect and study exoplanets), Pelletier and his team observed the planet as it passed in front of its host star on three separate occasions. These new observations uncovered a number of rock-forming elements in the atmosphere of WASP-76b, including sodium, potassium, lithium, nickel, manganese, chromium, magnesium, vanadium, barium, calcium, and, as previously detected, iron.

Due to the extreme temperatures of WASP-76b’s atmosphere, the elements detected by the researchers, which would normally form rocks here on Earth, are instead vaporized and thus present in the atmosphere in their gaseous forms. While these elements contribute to the composition of gas giants in our Solar System, those planets are too cold for the elements to vaporize into the atmosphere making them virtually undetectable.

The data not only suggests such elements exist in the solar system’s gas giants, but that such elements are common in solar systems elsewhere. That possibility increases the chances of other planets like Earth, capable of sustaining life as we know it, in addition to sustaining life as we don’t know it.

World Economic Forum decides its business is running space too!

8:13 am

We’re the government and we’re here to help you! The World Economic Forum (WEF) yesterday released its proposed new set of guidelines for mitigating space junk in orbit, even though some of the most important commercial satellite operators (SpaceX and Viasat) have not signed on.

The Space Industry Debris Mitigation Recommendations document, released by the WEF June 13, outlines recommendations to avoid collisions that can create debris by limiting the lifetime of satellites in orbit after they have completed their missions and improving coordination among satellite operators.

Among those recommendations is to establish a success rate for “post-mission disposal,” or removal of satellites from orbit after the end of their missions, to 95% to 99%. That disposal should be completed no more than five years after the end of each satellite’s mission.

You can read the guidelines here [pdf], which the WEF is pushing governments worldwide to adopt. Though SpaceX and Viasat have not signed on, 27 companies have endorsed the guidelines, including OneWeb, Airbus, Axiom, and a host of orbital tug and space junk removal startups, the latter of which all benefit from these guidelines.

While the proposals makes some sense, everyone in the space industry should remain skeptical, and resist the call for more government regulation. Once this power is given to government it will never be recanted, and will only grow with time. Moreover, all signs indicate that such interference by law by government is unnecessary. Both satellite operators and most rocket companies (the exception mostly China) have been making strong efforts to deal with the issue of space junk, for profit. The fact that there are a host of orbital tug and space junk startups right now illustrates this. Investors have realized there is money to be made removing satellites and space junk. They don’t need government telling them what to do.

BepiColumbo about to do third Mercury flyby

7:58 am

In its long journey to get into orbit around Mercury, BepiColumbo needs to do nine different flybys of the inner planets, with third fly-by of Mercury coming up on June 19, 2023.

The mission launched into space on an Ariane 5 from Europe’s Spaceport in Kourou in October 2018 and is making use of nine planetary flybys: one at Earth, two at Venus, and six at Mercury, to help steer into Mercury orbit.

After this flyby, the mission will enter a very challenging part of its journey to Mercury, gradually increasing the use of solar electric propulsion through additional propulsion periods called ‘thrust arcs’ to continually brake against the enormous gravitational pull of the Sun. These thrust arcs can last from a few days up to two months, with the longer arcs interrupted periodically for navigation and manoeuvre optimisation.

The spacecraft will zip past Mercury at a height of 147 miles. If all goes well, this dual orbiter mission, carrying both a European and a Japanese orbiter will arrive in 2025, beginning a planned three year mission in different complementary orbits.

Arianespace signs deal to study the possibility of using Orbex’s commercial rocket for launches

5:20 pm

In what must be considered a major sea change in Europe, Arianespace — the European Space Agency’s (ESA) official commercial launch company — has now signed a deal with Orbex, a rocket startup based in the United Kingdom, to study the possibility of using Orbex’s not-yet-launched Prime rocket for future European launches.

In particular, it is expected that future collaboration would be particularly beneficial for customers planning small satellite constellations, providing a flexible solution for Low-Earth Orbit (LEO) payloads. Light and heavy-lift launch vehicles could jointly support customers in deploying their initial constellations into the required orbital planes, provide precise injections of a smaller number of satellites through dedicated missions, as well as provide replenishment and replacement launches.

While the ESA began developing a partnership with Orbex back in 2021 when it awarded Orbex a development contract worth 7.45 million euros, for Arianespace to go directly to this independent company for launch services suggests the new policy of ESA to stop developing its own rockets but to become a customer hiring the rockets of private companies is gaining steam.

Today’s blacklisted American was arrested for quoting the Bible

Damon Atkins being arrested by McClure for quoting Bible
Atkins (r) being arrested by McClure for quoting Bible

They’re coming for you next: On June 3, 2023 there was a rally supporting the queer agenda in front of the Reading City Hall in Pennsylvania, partly instigated it appears by the endorsement of the city’s Democratic Party mayor, Eddie Moran. On the other side of the street were several Christians who vocally expressed their opposition to that rally.

Those Christians found themselves repeatedly harried by the police. As Matthew Wear noted, “I preached for 10 minutes or so until a tyrant cop laid hands on me and threatened to arrest me if I continued.” Soon thereafter a second Christian, Damon Atkins, began quoting the Bible in protest. That same policeman, Police Sergeant Bradley McClure, immediately arrested him.

According to an affidavit of probable cause, McClure claims that “[Atkins] was carrying a sign with a slogan written on it that showed his opposition to the event.” The video footage shows Atkins holding a sign that read “JESUS SAID GO AND SIN NO MORE.”

In the affidavit, McClure also claims that Atkins “began to yell to the people” attending the pride event. “I immediately approached him and told him that, while he was free to stand on that side of the street and hold his sign,” McClure wrote in the affidavit, “he could not cross the street nor yell comments intended to disrupt the event.” McClure added that Atkins “said he understood.”

But the video does not show Atkins agreeing to remain silent and Atkins told The Lancaster Patriot that he never agreed to McClure’s instructions.

The affidavit continues with McClure claiming that in less than a minute Atkins “resumed yelling derogatory comments to the people at the event.” The video records the only words from Atkins as “God is not the” immediately prior to McClure arresting him.

I have embedded the video taken by Wear below.

Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on April 23, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The scientists dub the features here merely as “land forms,” probably because it is difficult to explain the origins of many of these strange features. For example, why is the half-mile-wide crater filled that knobby terrain, far different than the surrounding plains? Similarly, what caused the small meandering ridges (less than five feet high) that appear to closely resemble the cave formation called rimstone dams?

And why is this terrain so generally flat and smooth?

As usual, the overview map helps explains some of this, but not all.

Boeing gets NASA contract to develop new airplane wing design

10:22 am

In its effort to reduce fossil fuel use and thus save us from being burned to death by global warming in only a decade, NASA has now awarded Boeing a contract to develop new airplane wing design that it predicts will lower fuel use by up to 30%.

The X-66A is the X-plane specifically aimed at helping the United States achieve the goal of net-zero greenhouse gas emissions by 2050. To build the X-66A, Boeing will work with NASA to modify an MD-90 aircraft, shortening the fuselage and replacing its wings and engines. The resulting demonstrator aircraft will have long, thin wings with engines mounted underneath and a set of aerodynamic trusses for support. The design, which Boeing submitted for NASA’s Sustainable Flight Demonstrator project, is known as a Transonic Truss-Braced Wing.

While developing a more efficient wing design is certainly worthwhile, having skepticism about this project is certainly reasonable. First of all, it seems somewhat strange to award Boeing such a contract at this time, considering NASA own experience with the company with Starliner, as well as that company’s problems with other government contracts for the military.

Secondly, the press release makes a big deal about the project getting an X-plane designation, an entirely superficial and PR related title that if anything suggests there is very little steak to this sizzle.

Third, it is unclear the nature of this contract. Is is cost-plus, or fixed price? The press release says NASA will “invest $425 million over seven years, while the company and its partners will contribute the remainder of the funding, estimated at about $725 million.” If cost-plus, this means nothing. Boeing will use any excuse to go over budget in order to get more money from NASA.

Finally, half a billion dollars to develop and test a new airplane wing design, using an already existing airplane, seems incredibly exorbitant. And to require seven years to build it seems ridiculously long.

All in all, I suspect the real goal of this project is to funnel tax dollars to Boeing to help keep it afloat, not to build a new green airplane.

New House bill proposes giving FAA responsibility for monitoring space junk

10:10 am

A just proposed House bill for reauthorizing the Federal Aviation Administration (FAA) also proposes giving that agency the responsibility for monitoring space junk.

The bill instructs the FAA to establish a program to track objects “that are potential sources of covered airborne debris” with a focus on identifying those about to reenter and could pose a risk to aircraft in airspace. That program would coordinate with the FAA’s air traffic control system to identify airspace that needs to be closed for a reentry. It would allow the FAA to establish its own space situational awareness (SSA) facilities and work with other federal agencies, companies or international organizations for data on such objects.

While the focus of the bill is tracking debris to assess airspace risks, the bill does enable additional uses of the data the FAA collects. In particular, it directs the FAA to offer “a basic level of data, information, and services” at no charge. That includes maintaining a public catalog of space objects and “emergency conjunction notifications” of such objects.

The article at the link notes that this new FAA job would also duplicate work of the Space Force, as well as a new Commerce Department office tasked with similar responsibilities. It also duplicates the same responsibilities the FCC has created for itself, outside of its statutory authority.

In other words, there is a factional turf war going on within the swamp, with each faction attempting to establish its territory and control over this work.

The result? Expect Congress to allow this duplication to go forward, funding all three efforts. As we all know, money grows on trees, and hiring as many Washington bureaucrats is the most important thing Congress can do, even if those bureaucrats don’t do anything useful.

Japanese government adopts revised space policy emphasizing defense

10:00 am

The Japanese government today announced a revision to its space policy, with the changes mostly focused on increasing that nation’s military surveillance and reconnaissance capabilities in space.

Though defense and security appeared to be the focus of the revision, there were hints this would be achieved through a greater use of the competitive free market.

The government also vowed to bolster collaboration between the Defense Ministry and the Japan Aerospace Exploration Agency in a bid to provide support to private companies engaged in critical space technology development, the blueprint says. By attempting to stimulate private-sector-led development in space, the government will aim to reduce costs in the face of budget constraints, it adds.

Japan has traditionally operated as the U.S. used to, by letting its space agency JAXA do and control everything. JAXA in turn has routinely hired established companies like Mitsubishi to build what it wants, while retaining all control and ownership. The result has been a moribund effort, with Japan at present having no low cost rocket that can compete on the international market for business.

Whether this new policy will allow new companies to compete with the big established players remains unknown.

Forgotten Weapons – Girardoni Air Gun

SpaceX launches 72 smallsats; lands a Falcon 9 1st stage for the 200th time

3:22 pm

SpaceX today successfully launched 72 smallsats using its Falcon 9 rocket, lifting off from Vandenberg Space Force Base in California.

With this launch, SpaceX achieved a significant milestone, successfully landing a Falcon 9 first stage for the 200th time, an achievement that for more than a half century all managers and most engineers in the rocket business claimed was not only impossible, but impractical. They insisted that the first stage would not be able to be reused because of the stress of launch. SpaceX has proved these close-minded fools very wrong. This particular first stage completed its ninth mission on this flight, a number that has become very routine for SpaceX’s Falcon 9 first stages. The stage landed back at Vandenberg,

As of posting the satellites have not all deployed.

40 SpaceX
22 China
8 Russia

American private enterprise now leads China 45 to 22 in the national rankings, and the entire world combined 45 to 38, with SpaceX by itself leading the rest of the world, excluding other American companies, 40 to 38.

The evidence shows clearly that Biden has worked to squelch Elon Musk and SpaceX

Starship #15 about to land
Starship prototype #15, during its successful suborbital test flight in May 2021

The public concerns expressed last week by one NASA official about the regulatory delays caused by the FAA to SpaceX’s Starship/Superheavy development program illustrated once again my sense that there had been a stark change in how SpaceX was being regulated by the federal government, from the Trump to the Biden administration. Under Trump, SpaceX was moving fast, launching test flights frequently. Under Biden, all such test flights appeared to grind to a halt.

For example, it seemed to me that during the Trump administration the FAA allowed SpaceX to complete its investigations of explosions or launch failures quickly, so they could proceed as quickly to another test launch, sometimes only weeks later. After the first orbital test flight of Superheavy/Starship on April 20, 2023, however, the FAA responded quite differently, demanding the right to oversee a full investigation that it also implied would take many months.

Others have disputed this assertion. For example, space reporter Doug Messier commented about my analysis, stating that the FAA’s insistence on a lengthy investigation into the April 20, 2023 Superheavy/Starship orbital test flight failure was simply standard procedure. “I don’t think this represents any change in policy. This is how it’s been done for years,” Messier wrote. “It’s easy to scapegoat FAA as THE cause of the problem, and speculate about nefarious actions by the Biden Administration.”

Who is right? Am I being paranoid? Or is Messier being naive? As Howard Cosell used to say on Monday Night Football, “Let’s go to the videotape!” Or in this case, let’s take a hard detailed look at how SpaceX’s test program for Starship/Superheavy came to a screeching halt when Joe Biden took over the White House from Donald Trump.

From 2018, when SpaceX began first cutting metal on Starship prototypes, to May 2021, the company did eight suborbital test flights and at least six tank and static fire engine tests, with some resulting in explosive destruction. Below is a list of those tests (There were more such engine and tank tests during that time, but these were ones I could quickly find).

Alongside its hazy shape, NGC 7292 is remarkably faint. As a result, astronomers classify NGC 7292 as a low surface brightness galaxy, barely distinguishable against the backdrop of the night sky. Such galaxies are typically dominated by gas and dark matter rather than stars.

Astronomers directed Hubble to inspect NGC 7292 during an observational campaign studying the aftermath of Type II supernovae. These colossal explosions happen when a massive star collapses and then violently rebounds in a catastrophic explosion that tears the star apart. Astronomers hope to learn more about the diversity of Type II supernovae they have observed by scrutinising the aftermath and remaining nearby stars of a large sample of historical Type II supernovae.

NGC 7292’s supernova was observed in 1964 and accordingly given the identifier SN 1964H. Studying the stellar neighbourhood of SN 1964H helps astronomers estimate the initial mass of the star that went supernova, and could uncover surviving stellar companions that once shared a system with the star that would become SN 1964H.

I searched but was unable to locate any 1964 images of this galaxy when the supernova was still visible, so I could not pinpoint its location in the picture. It has long since faded away.

Note that the reddish smudges scattered throughout the picture are likely galaxies so far distant that their light has shifted entirely into the reddish spectrum. This likely places them one to several billions of light years away, not millions.

SpaceX launches another 52 Starlink satellites

12:21 am

Just after midnight tonight (Pacific) SpaceX successfully launched another 52 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage successfully completed its ninth flight, landing on a drone ship in the Atlantic, the 199th time that SpaceX has accomplished this so-called impossible task. The two fairing halves completed their fourth and fifth flights respectively.

The leaders in the 2023 launch race:

39 SpaceX
22 China
8 Russia
5 Rocket Lab

American private enterprise now leads China 44 to 22 in the national rankings, and the entire world combined 44 to 38, with SpaceX by itself leading the rest of the world, excluding other American companies, 39 to 38.
