Leftist students take-over building illegally and by force at Vanderbilt

The lawless left: Because Vanderbilt University officials canceled a vote on a student amendment to the student government constitution, on March 25, 2024 about thirty students broke into the chancellor’s office, assaulting a security guard as they did so, and occupied it about 22 hours before police forced them out.

The university canceled the amendment vote because it would require the boycott of any businesses linked with Israel, and thus would likely violate federal and state laws and would make the university “ineligible for new state contracts and could have existing contracts voided.”

Whether or not the cancellation was right, the violence of the students is typical of the spoiled-child tantrums of the left, that assume it has the right to do anything at all, including violence and trespass, if it doesn’t get what it wants.

In a statement, the Vanderbilt spokesperson said the protest was “not a peaceful one.”

Japan awards development agreements with four rocket startups

Capitalism in space: Japan’s space agency this week awarded development agreements to four Japanese rocket startups, signaling that nation’s attempt to shift from depending on JAXA’s government-built rockets to becoming a customer of an industry of competing commercial rocket companies.

Japan Aerospace Exploration Agency (JAXA) and Interstellar signed a basic agreement in March. Space One, whose Kairos solid rocket exploded seconds after liftoff earlier this month, was also selected under the JAXA-SMASH (JAXA-Small Satellite Rush Program) initiative. Two further companies also signed basic agreements. These are Space BD and Mitsui Bussan Aerospace, which offer services aimed at the commercial utilization of space.

The agreements mean the companies will have priority for future contracts. These are designed to support private-sector entities capable of launching satellites developed under JAXA’s small satellite missions and advance the commercialization of space transportation services.

These deals are part of a new policy announced in November that includes $6.6 billion to help encourage the growth of a Japanese commercial space sector, independent of that nation’s space agency.

It remains uncertain whether JAXA will let go the purse strings and actually allow these new companies ownership of what they do. The deals as described sound like the agency is using its power to attempt to capture the companies, rather than encourage their independent growth.

We shall have to wait and see. On its face this announcement is very good news for Japan’s space industry, as it suggests that things might be changing.

A detailed look at the international partners for China’s Moon base

Link here. The article provides a nice summary of who has signed on to China’s project to build a Moon base in competition with the American Artemis project, prompted by the announcement that an astronomical association in Columbia has now signed on.

The contrast is stark between the nations that have signed the Artemis Accords to participate in the American project (36 so far) and the entities that have partnered with the Chinese. China at present only has seven partner nations (Belarus, Pakistan, Azerbaijan, Russia, Venezuela, South Africa, Egypt), only one of which, Russia, has any space capabilities. The remaining nine partners are all academic organizations of one kind or another, all of which also have little or no major space capabilities.

Essentially, these partners are mostly PR by China to make it appear it has an international team. In reality almost all of its lunar project will be done by China. China doesn’t even expect Russia to contribute that much. As the article notes, “China has regularly omitted any mention of Russia as an ILRS partner” since the Russia invaded the Ukraine in February 2022. Before then Russia’s ability to accomplish much of anything new in space had long been questionable, and since then the doubts have escalated.

Though many of the nations who have signed the Artemis Accords are as weak, the list also includes almost all the world’s major players in space, such as France, Germany, India, Japan, and Luxembourg.

Like the Cold War, the western capitalist alliance is larger and more capable, because no one really wants to join an partnership that discourages freedom and private enterprise.

Martian waves of ridges and cracks

Martian waves of ridges and cracks
Click for original image.

In preparing today’s cool image I initially planned to post an picture taken on December 26, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), as it showed a strange series of ridges that almost resembled waves or ripples on a pond.

In digging into MRO’s context camera archive to get the larger context, however, I immediately switched to the photo on the right, cropped, reduced, and sharpened to post here. Taken on December 17, 2010, it shows a much more mysterious and striking set of geological features than the closer view of the high resolution image, with the wave-shaped ridges on its western half but another set of wave-shaped cracks on its eastern half.

Even more intriguing, the arcs for the ridges curve in the opposite direction from the arcs for the cracks. It is almost as if there were two flows moving in opposite directions, right next to each other.

The remnant of the supernova from 1181, as seen in multiple wavelengths

Supernova remnant as seen in multiple wavelengths
Click for original image.

Using a number of different telescopes and observing in many wavelengths outside the visible spectrum, astronomers have produced a new composite image of the remnant of a supernova that was detected in the year 1181 and remained visible to the naked eye for about six months.

That composite picture is to the right, cropped and reduced to post here. From the press release:

X-ray observations by ESA’s XMM-Newton (blue) show the full extent of the nebula and NASA’s Chandra X-ray Observatory (cyan) pinpoints its central source. The nebula is barely visible in optical light but shines bright in infrared light, collected by NASA’s Wide-field Infrared Space Explorer (red and pink). Interestingly, the radial structure in the image consists of heated sulfur that glows in visible light, observed with the ground-based Hiltner 2.4 m telescope at the MDM Observatory (green) in Arizona, USA, as do the stars in the background by Pan-STARRS (white) in Hawaii, USA.

Because the remnant is so dim in visible light, it has taken years of searching to locate it.

SLIM survives its second lunar night, re-establishes contact

SLIM's view after surviving its 2nd night on the Moon
Click for original image.

According to Japan’s space agency JAXA, the SLIM lunar lander has successfully survived its long night on the Moon, re-establishiing contact with ground controllers yesterday.

Last night, we received a response from #SLIM, confirming that the spacecraft made it through the lunar night for the second time! Since the sun was still high and the equipment was still hot, we only took some shots of the usual scenery with the navigation camera

One of those pictures is to the right, reduced slightly to post here. It looks west across the floor of Shioli Crater, with the far rim about a thousand feet away. The picture is identical to previous images, tilted because the spacecraft landed on its side and has limited scientific capabilities, being primarily an engineering test mission.

That this engineering test has now survived two lunar nights speaks well for its design. It tells us that future Japanese lunar landers (and rovers) will have a good chance of surviving for a long time on the Moon.

Scientists release detailed geological map of the landing site for Europe’s Franklin rover

Low resolution cropped section of map
Click for original image.

Scientists today released a new high resolution and very detailed geological map of the landing site for Europe’s Franklin rover, produced using orbital data from the U.S.’S Mars Reconnaissance Orbiter and Europe’s Trace Gas Orbiter.

A very low resolution version of the map is to the right.

The work was divided into 134 one-square-kilometre areas, so that the [80-person] team could fully cover the estimated landing area. Scientists used a web-based system that allowed everyone to work on the map in parallel. The software was provided by NASA’s Jet Propulsion Laboratory and set up at ESA [European Space Agency]. Data came from the Colour and Stereo Surface Imaging System (CaSSIS) onboard the ExoMars Trace Gas Orbiter and several instruments on NASA’s Mars Reconnaissance Orbiter (MRO), including the HiRISE camera, which returns images from Mars orbit at 25 cm per pixel.

The mapping leads then pieced together the information on all the areas to form a coherent map that shows the geology of the landing site in unprecedented detail. The map includes the main types of bedrock, and structures with distinct shapes like ridges and craters. It even features the material that rests on top, for example blown by the wind, or thrown long distances when meteorites impacted the surface.

The result is the highest resolution map of Oxia Planum yet, created at a scale of 1:25 000, by which every centimetre equals 250 metres on the martian surface. An average drive of 25 to 50 metres a day for Rosalind Franklin would be one to two milimetres on the map.

The team had the extra time to compile this map because the launch of Franklin to Mars was delayed a number of times because of engineering issues and the Ukraine War, which ended the Europe’s partnership with Russia, requiring ESA to find other means to launch and land the rover.

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

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

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

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

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.

China’s Long March 6 rocket launches remote sensing satellite

China yesterday successfully launched a classified remote sensing satellite, its Long March 6 rocket lifting off from its Taiyuan spaceport in the northeast of China.

No word on where the rocket’s four solid-fueled strap-on boosters and liquid-fueld core stage crashed inside China.

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

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

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.

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

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]:

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

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

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

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

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

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

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.

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.
