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

Data from Perseverance suggests the delta in Jezero Crater was formed by a wide variety of different “fluvial” events

9:43 am

Jezero Crater delta
Jezero Crater delta

Using data from the Perseverance rover in Jezero crater, scientists now conclude that the delta that poured through a gap in the crater’s rim was formed by a wide variety of different “fluvial” events, not a steady flow as previously assumed.

From the paper’s conclusions:

The origin of this variability as well as that of the high discharge represented by the boulder conglomerate is still unknown. Realistic hypotheses include seasonal variations due to melting of snow, glacial input with possible episodic surges punctuating more regular fluvial input, or arid climate type of flows with intense storms and related flash floods.

We do not speculate further about the nature of fluvial activity in this study. However, the variability and the presence of high discharge rates have important implications on the lake evolution. Firstly, previous modeling of Jezero delta formation used steady-state discharge rates to estimate the time required to form the delta, an assumption that we can no longer justify according to our observations. Secondly, estimates of discharge rates … may be used as upper limits for some of the peak discharge rates, although the number of flood events is still difficult to determine from the sparse outcrops and the ubiquitous presence of scree.

In other words, the delta was not formed by a single event or a long stream of liquid flowing into the crater to form the lake that scientists believe once filled the crater. Instead, that flow varied, involved numerous distinct and different events over time, and likely included glacial ice transport as well.

Not that this is a surprise, but as always, the closer we get to a planet and the more detailed our data about it, the more complicated we find its nature and origins.

Members of Texas Space Commission unveiled

9:27 am

The governor of Texas, Greg Abbott, yesterday revealed the names of the 18 individuals who will head the Texas Space Commission, created by the legislature to encourage the development of that state’s commercial space industry.

The Texas Space Commission will be tasked with developing a statewide strategy that promotes innovation, creates incentives (including grant funding) and develops workforce training. They initially have $350 million to work with, $150 million budgeted for grants and $200 million for a new research and training facility built by the Texas A&M University System.

The Texas Aerospace Research and Space Economy Consortium, which is part of the Texas Space Commission, will identify research and development opportunities and find ways to further integrate space into the Texas economy.

The commission appears strongly made up of representatives from many commercial companies, including the big companies SpaceX, Lockheed Martin, and Boeing as well as a number of newer smaller companies. Linked as it is so closely with the state government, this commission will be well placed to eliminate any obstacles within the state to commercial development.

The spiraling magnetic field surrounding the Milky Way’s central supermassive black hole

9:19 am

The magnetic field lines surrounding Sagittarius A*
Click for original image.

Astronomers have now produced the first detailed image of polarized light surrounding the Milky Way’s central supermassive black hole, dubbed Sagittarius A* (pronounced “Sagittarius A-star”) which in turn maps out the spiraling field lines of that black hole’s magnetic field.

The image to the right, reduced to post here, shows that image. From the press release:

“What we’re seeing now is that there are strong, twisted, and organized magnetic fields near the black hole at the center of the Milky Way galaxy,” said Sara Issaoun, CfA NASA Hubble Fellowship Program Einstein Fellow, Smithsonian Astrophysical Observatory (SAO) astrophysicist, and co-lead of the project. “Along with Sgr A* having a strikingly similar polarization structure to that seen in the much larger and more powerful M87* black hole, we’ve learned that strong and ordered magnetic fields are critical to how black holes interact with the gas and matter around them.”

Light is an oscillating, or moving, electromagnetic wave that allows us to see objects. Sometimes, light oscillates in a preferred orientation, and we call it “polarized.” Although polarized light surrounds us, to human eyes it is indistinguishable from “normal” light. In the plasma around these black holes, particles whirling around magnetic field lines impart a polarization pattern perpendicular to the field. This allows astronomers to see in increasingly vivid detail what’s happening in black hole regions and map their magnetic field lines.

Despite this similarlity, it still remains a mystery why the much larger M87 black hole is very active while Sagittarius A’ remains generally quiet.

Engineers resolve issue on IXPE space telescope

9:01 am

Engineers have resolved the issue on the IXPE (Imaging X-ray Polarimetry Explorer) space telescope that was jumbling the data it was sending to Earth, and expect to return it to full science operations shortly.

On March 26, using procedures developed following that previous interruption, the team initiated a spacecraft avionics reset to address the issue, which put IXPE into a planned safe mode. The team has confirmed that IXPE is once again transmitting valid telemetry data and is now working to resume science operations, in as rapid and safe a manner as possible. The spacecraft is in good health.

The “previous interruption” was in 2023. In both cases it appears that simply rebooting the telescope’s software fixed the problem.

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.

Part 2: A further list of upcoming Democratic Party election chaos

2:21 pm

The Democratic Party: hostile to freedom and fair elections

In part one of this series yesterday I outlined one Democratic Party scenario for stealing a Trump election victory, based on the possibility that they might regain control of both Houses of Congress this year due to Republican resignations, and use that power to interfere with the election result as a lame duck Congress.

To do this however will require some groundwork. Today I will to outline several of the far more likely tactics the Democratic Party will use in the coming months, before, during, and after the election, to make the first scenario above more doable, should it be necessary due to a Trump victory. These tactics are also intended to use fear and violence to supress the Republican vote while energizing Democrats.

Bursting bubbles of water gas on Mars

Bursting bubbles on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and enhanced to post here, was taken on January 12, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Because of a technical issue that leaves a blank strip down the center of recent high-res MRO images, I have filled in that gap using a MRO context camera photo taken on January 12, 2015. The resolution is much less, but by doing so we can see the ground features as a unit.

What are we looking at? According to the scientists, this picture shows “fresh-looking ruptures,” referring to the broken line of sharp tears inside that meandering canyon that almost resemble a fresh wound in flesh. As this location is at 28 degrees south latitude, it lies on the edge of dry equatorial regions, where orbital images have sometimes found hints of a few remaining buried glaciers that are much more common closer to the poles.

In this case it appears the warmer equatorial climate has acted to heat up the buried ice so that it sublimated into gas. At some point the gas pressure caused the surface to burst, much like bubbles bursting on the surface of a pot of simmering tomato sauce, leaving behind these scars.

Report: 3D printing in space

10:44 am

A new report released today [pdf] from the space think tank Intro-act provides a nice detailed summary of the economic and technological state of 3D printing industry in space.

The report first outlines the types of 3D printing presently available, using plastics and metals, and then outlines the advantages of printing things in orbit rather than carrying them up from Earth. Essentially, 3D printers are the real version of replicators seen in sci-fi movies, except that reality requires much more complexity, including a whole range of different machines designed for specific materials and final products.

The report lists four companies of note:

Made in Space (acquired by Redwire Corp.), Relativity Space, and AI SpaceFactory are the leading companies in the 3-D printing segment. With the addition of Vaya Space, the list provides a more comprehensive overview of the companies that are pioneering the use of 3-D printing technology in the realm of space exploration and development, showcasing the diverse applications and innovative strategies being employed in this exciting field.

Each company appears to have a different focus. Redwire is developing 3D printers for use on ISS, Relativity developing 3D printers for building rocket components, and AI Spacefactory developing 3D printed space colonies for Mars or the Moon.

If I had to choose which company to bet on, my pick would be Relativity followed by Redwire. The former’s large 3D printing technology for rockets can be very easily shifted to other uses and products, giving it a product of great value far beyond space. Redwire meanwhile has already launched and operated printers on ISS, proving it can provide that technology to future space stations.

This industry is however in its infancy. As the private space stations presently under construction launch, their need for this technology will skyrocket, and thus there will be opportunities galore.

Orbital tug startup ExLabs plans mission to asteroid Apophis in 2028

9:03 am

The orbital tug startup Exploration Labs (ExLabs) has announced it is planning to use its tug to deliver three cubesats on a rendezvous mission to asteroid Apophis in 2028, shortly before the asteroid does a close fly-by of Earth in April 2029.

The article at the link provides no other information about this mission. In searching the web I was unable to find anything further. It seems this mission is at present nothing more than a proposal, issued at this time mostly for public relations purposes to showcase the abilities of its proposed orbital tug, presently under development.

This conclusion does not mean the mission won’t happen, only that it is very far from a reality.

Intuitive Machines: Odysseus is dead

8:53 am

In a tweet on March 23, 2024 the company Intuitive Machines announced that the mission of its first lunar lander, Odysseus, is officially over with the spacecraft failing to come back to life after sunrise on the Moon.

As of March 23rd at 1030 A.M. Central Standard Time, flight controllers decided their projections were correct, and Odie’s power system would not complete another call home.

The engineers had begun listening for a signal on March 20th, when their computer models said enough sunlight would reach the solar panels to charge its communications system.

The failure of the lander to survive the lunar night is a disappointment, but it was never considered a strong possibility. Right now the company’s main task is to prevent the issues that caused Odysseus to land too fast and tip over, so that the next two missions, scheduled for either this year or next, each deliver their payloads properly on the Moon’s surface.

Pushback: Smithsonian to pay Catholic students $50K and publicly apologize for ejecting them from Air & Space for wearing pro-life hats

5:25 pm

The evil hat that Air & Space banned
The evil hat that Air & Space officials banned

Bring a gun to a knife fight: The Smithsonian has agreed to pay twelve Catholic students $50K and publicly apologize to them for ejecting them from the Air & Space museum last January because they were wearing pro-life hats.

That hat is to the right. Though many others were wearing t-shirts and hats with other political statements, museum officials singled these students out for harassment and ejection. According to their lawyer,

Once in the museum, they were accosted several times and told they would be forced to leave unless they removed their pro-life hats. The group all wore the same blue hat that simply said, “Rosary PRO-LIFE.” Other individuals in the museum were wearing hats of all kinds without issue.

The museum staff mocked the students, called them expletives, and made comments that the museum was a “neutral zone” where they could not express such statements. The employee who ultimately forced the students to leave the museum was rubbing his hands together in glee as they exited the building.

According to the settlement deal [pdf]:

Part 1: The expected upcoming election chaos caused by the left’s hatred of any opposition

4:33 pm

The Democratic Party: hostile to freedom and fair elections

The kerfuffle this week at MSNBC because NBC had hired former Republican National Committee (RNC) chairwoman Ronna McDaniel is important not because of what eventually happened (MSNBC quickly announced McDaniel was banned though she would still appear on NBC), but by what it reveals of the left’s political class.

Democrat politicians everywhere, both pretending to be journalists at MSNBC as well as within the leaders of the Democratic Party, complained that it was unacceptable to hire a former Republican Party leader, simply because she had dared express opinions and conclusions they disagreed with.

“The free and independent press is fundamental to our democracy and has and continues to face unprecedented attacks by Donald Trump and his lackeys – including Ronna McDaniel – to chip away at its credibility and allow space for MAGA lies and deceit,” Democratic National Committee Chairman Jaime Harrison fumed in a statement. “There should be no debate about the truth in our political discourse. Ronna McDaniel is a proven liar, and has no place in an honest and objective conversation about the future of this country.”

Gee, I don’t remember anyone complaining when NBC hired Chuck Todd, who hosted fund-raising events for Hillary Clinton and whose wife is a major leftist strategist who did campaign work for Bernie Sanders. Nor did anyone complain when ABC hired George Stephanopoulos, a longtime Democratic Party campaign worker who was a major player in Bill Clinton’s campaign. Nor did any of these so-called journalists complain about these hires:

France to award four rocket startups launch contracts worth as much as 400 million euros

11:41 am

Capitalism in space: According to a story today at the European Spaceflight website, the French government will later this week announce contract awards to four different rocket startups worth as much as 400 million euros.

The four launch startups that will receive a combined €400 million in subsidies are HyPrSpace, Latitude, Sirius Space Services, and the ArianeGroup subsidiary MaiaSpace.

The HyPrSpace OB-1 and Latitude Zephyr rockets will be the smallest of the lot and will be capable of delivering between 100 and 200 kilograms to low Earth orbit. The Sirius 1, Sirius 13, and Sirius 15 rockets will be capable of delivering between 175 and 1,100 kilograms to orbit. The Prometheus-powered Maia rocket is expected to be the most powerful, with a payload capacity of up to three tonnes when launched in its expendable configuration.

All four companies however will only receive a small upfront payment, with the bulk of the award only paid if a company achieves a maiden launch by 2028.

That the French government is now signing deals with new private and independent launch companies and not with Arianespace, the commercial arm of the European Space Agency (ESA) that has always been dominated by the French, is a major development. Up until now most of the action encouraging independent rocket companies has come from Germany and Spain. That France has now joined the party signals the almost certain death knell to the failed two decade-long effort by Arianespace to make a profit, even when it controlled about 50% of the launch market.

Expect the government monopoly of Arianespace to fade away in the next five years. Expect it to be replaced with a thriving industry of mulitple rocket companies, all charging less and coming up with new ways to lower cost.

South Texas booming due to arrival of SpaceX

11:29 am

Link here. The article details the major tourism and industry dollars that have come into existence in the Brownsville region since SpaceX established its Boca Chica launch facility, including major development now underway to cater to the tourist business of travelers eager to get a close look at a Starship/Superheavy launch.

The article gives a sense of the reality on the ground. While the anti-Musk activist groups sue SpaceX in their attempt to shut down Starship/Superheavy development, claiming it is harming the region, stories like this put the lie to those claims.

The tangled view of astronomers

11:06 am

A protostar in formation
Click for original image.

The uncertainty of science: The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope as part of a survey of young stars surrounded by an edge-on dust disk. From the caption:

FS Tau is a multi-star system made up of FS Tau A, the bright star-like object near the middle of the image, and FS Tau B (Haro 6-5B), the bright object to the far right that is partially obscured by a dark, vertical lane of dust. The young objects are surrounded by softly illuminated gas and dust of this stellar nursery. The system is only about 2.8 million years old, very young for a star system. Our Sun, by contrast, is about 4.6 billion years old.

The blue lines on either side of that vertical dust lane are jets moving out from FS Tau B. The caption says their asymetrical lengths are likely due to ” mass is being expelled from the object at different rates,” but it just as easily be caused by the angle in which we see this object, making the nearer jet seem longer than the one behind.

That astronomers cannot move around such an object and see it from many angles explains the headline of this post. We can only see astronomical objects from one angle, and when they are complex objects such as this one, a large part of the research problem is disentangling the shapes we see into a coherent picture. Spectroscopy helps a lot, as it provides information about the speed and direction of different parts of the object, but even this can be enormously complicated and difficult to interpret.

Remember these facts when you read news reports about astronomical research. No matter how certain the press release sounds, its certainty is always tempered by many unknowns, some very pedestrian but fundamental.

UK Space Agency proudly grows

9:27 am

The United Kingdom Space Agency today announced that it is opening four new offices in four different cities, giving it a brand new headquarters as well as a total of five regional offices.

The new HQ at Harwell is due to open in June, while offices at William Morgan House in Cardiff and Space Park Leicester will open in April, with the office at Queen Elizabeth House, in Edinburgh, opening later in the summer.

In addition, the agency will retain its offices in London and Swindon.

Will this expansion alleviate the serious red-tape issues in the United Kingdom that killed Virgin Orbit and have delayed launches at its two new spaceports in Scotland? I have my doubts. The licensing problems in the UK have centered on the number of different agencies and offices that must issue approvals to private space companies. While it might make sense for the UK Space Agency to hire more people, if anything it should be streamlining its operations to one central place.

It appears instead that this bureaucracy is doing what all government bureaucracies do, expanding and growing at the cost of private enterprise. I don’t see how opening many different small offices can possibly help make the licensing procedure faster or easier.

Boom’s one-third-scale prototype supersonic jet finally takes off

9:05 am

The private startup Boom has finally flown its third-scale prototype supersonic jet, dubbed XB-1, on its first short flight, taking off on March 22, 2024 from the flight test facility in Mojave, California.

Following behind was Test Pilot Tristan “Geppetto” Brandenburg in a T-38 chase plane to observe the flight and confirm altitude and speed. With a length of 62.6 feet (19 m) and a wingspan of 21 ft (6 m) , the XB-1 achieved an altitude of 7,120 ft (2,170 m) and speeds up to 238 knots (273 mph, 440 km/h) under the force of its three GE J85-15 engines generating a maximum thrust of 12,300 lbs.

According to Boom, once its aerodynamic characteristics and flight worthiness are confirmed, the XB-1 will increase speed until it is flying on later tests in excess of Mach 1.

This prototype supersonic test plane was first unveiled in 2020, four years ago, but runway taxi tests did not begin until 2023. I suspect the Wuhan panic contributed to the three year delay between unveiling and first tests, though this is speculation.

The goal is to build the first commercial superonic passenger plane since the Concorde. At present Boom has a contract from United for fifteen Boom 12-passenger planes, plus development deals with Boeing, and Japan Airlines.

Antenna for joint NASA-ISRO radar satellite needs fix, delaying launch

8:50 am

The large deployable antenna for a joint NASA-ISRO radar satellite, dubbed NISAR, that was targeting a spring launch will require an extra coat of reflective material, thus delaying the satellite’s launch until the second half of this year.

In a March 22 statement, NASA said a new launch date for the NASA-ISRO Synthetic Aperture Radar (NISAR) mission will be set at the end of April because of work to protect the spacecraft’s reflector, an antenna that is 12 meters across when fully deployed, from temperatures when in its stowed configuration. “Testing and analysis identified a potential for the reflector to experience higher-than-previously-anticipated temperatures in its stowed configuration in flight,” NASA said in the statement. To prevent those increased temperatures, a “special coating” will be applied to the antenna so that it reflects more sunlight.

That work, NASA said, requires shipping the antenna, currently with the rest of the NISAR spacecraft in India, to a facility in California that can apply the coating. NASA did not state how long the process of applying the coating, as well as shipping the antenna to California and then back to India, will take.

It appears that the need for this additional coat was discovered during environmental testing by ISRO engineers in India as part of its preparation for launch on India’s GSLV rocket. Based on the JPL website for this mission, it appears this antenna system was built by JPL.

NASA is providing the mission’s L-band synthetic aperture radar, a high-rate communication subsystem for science data, GPS receivers, a solid-state recorder and payload data subsystem. ISRO is providing the spacecraft bus, the S-band radar, the launch vehicle and associated launch services.

Though the purpose of the final environmental testing prior to launch is specifically to find such issues and correct them, the question remains why this issue occurred. One can’t help wondering if the many management problems detailed at JPL in several reports (here, herej, here) might have contributed, including the organization’s total commitment since 2022 to Diversity, Equity, and Inclusion quotas, making skin color and sex the primary qualifications for hiring, rather than skill, education, or talent.

Russians launch three astronauts to ISS

2:20 pm

The Russians today successfully launched three astronauts to ISS, its Soyuz-2 rocket lifting off from Baikonur in Kazakhstan.

The Soyuz is scheduled to dock with ISS on March 25, 2024. The Russian and Belarus astronauts will stay on board ISS for about two weeks, returning to Earth on an Soyuz-2 capsule that is presently docked to ISS, taking with them an American who has just completed six months in space. The American on today’s launch will now start her own six month mission, and will return in September with two Russian astronauts who are presently on a year long mission, one of whom will likely set a new duration record for a woman.

The leaders in the 2024 launch race:

28 SpaceX
12 China
4 Rocket Lab
4 Russia

American private enterprise still leads the rest of the world combined in successful launches 33 to 22, while SpaceX remains ahead of the entire world, including American companies, 28 to 27.

Martian vent or sink?

A Martian vent or sink?
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and enhanced to post here, was taken on January 29, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

Though the scientists label this image showing “channels”, what I see is either a vent or a sink, with the channels to the south indicating past flows either coming out of the depression or into it. The uncertainty exists because the surface grade in this region is essentially flat. There is a lot of small up and down variations, but overall it is very difficult to determine the general trend, suggesting that when the depression and channels formed the grade was different, and there is no way from this data to determine the angle at that time.

Were the flows that created the channels lava or water or ice? Knowing the grade when these channels formed would help answer this question, but other research now suggests the latter.

Australia moves to make skin color and sex more important in hiring space engineers than skill or knowledge

9:18 am

A new industry group, established with full support of the Australian government, has been formed to encourage the hiring of minorities and women in that nation’s space industry, merely because they are minorities and women.

The Australian Space Diversity Alliance (ASDA) said it aims to support senior leaders and minimise the barriers that marginalised groups face. It comes after a series of reports have shown the sector is lagging behind others in regard to gender disparity, and alongside a talent shortage critics say can only be overcome with a more diverse intake.

ASDA was founded by eight industry figures, including Defence Council of Victoria’s Anntonette Dailey, ANU’s Dr Cassandra Steer, and Raytheon’s Linda Spurr. Defence Connect is one of the group’s industry partners, alongside five state governments, the iLAuNCH Trailblazer initiative, and communications agency The Write Space.

It makes the typical and very bogus claims of these Diversity, Equity, and Inclusion (DEI) programs that because woman comprise only 20% of the people in the space industry and minorities only 5%, bigotry must be involved. And the only solution is more bigotry, by favoring applicants from those groups even it they are less qualified than others.

The possibility that women and minorities might simply not be interested in doing this work is a reality that these race hustlers simply can’t tolerate. No, if women and minorities aren’t represented at a level we believe appropriate, we will make it so, regardless of skills, talent, knowledge or experience.

Expect the entire Australian space industry to suffer because of this effort.
