New orbital image of Curiosity on Mount Sharp

10:01 am

Though this is not the first time Curiosity has been spotted from orbit by Mars Reconnaissance Orbiter (MRO), the image to the right, reduced and sharpened to post here, might be the coolest, because it shows clearly the mountainous terrain within which the rover presently travels. The cliff on the picture’s right is 400-foot-high Kukenan.

NASA’s Curiosity Mars rover appears as a dark speck in this image captured from directly overhead by the agency’s Mars Reconnaissance Orbiter, or MRO. The orbiter is equipped with a camera capable of viewing objects the size of a dinner table on the Red Planet’s surface.

The camera, called the High-Resolution Imaging Science Experiment (HiRISE), has viewed spacecraft on the surface many times before. Here, it captured Curiosity driving up a steep slope on Dec. 29, 2023, the 4,051st Martian day, or sol, of the rover’s mission.

At present the Curiosity team is using the rover to analyze the material produced from the rover’s 40th drill hole, and thus it has not moved significantly for several weeks.

More orbital tugs reach orbit

9:44 am

When SpaceX launches a large number of smallsats and payloads on a Falcon 9 launch, as it did on March 5 from Vandenberg in California, it routinely takes several days or even months for the results from each payload or smallsat to trickle in. Two reports today illustrate the growing cottage industry of orbital tugs.

First, a company named Apex has successfuly demonstrated its first service module for satellites, designed to provide the basic services needed for satellites so that companies can focus on designing their primary mission rather than reinventing a basic satellite each time. The module was launched on March 5th, and has been operating as expected. The company hopes to begin mass producing this service module in a new factory later this year.

Second, a new orbital tug company from France, Exotrail, has successfully deployed a cubesat from its first tug. That tug was launched on a Falcon 9 smallsat launch in November, and has been testing operations since. After releasing that cubesat for Airbus’s defense division, the tug is continuing operations, acting as the service module for a second payload from Belgium that is testing its own gyros and reaction wheels for controling smallsat orientation.

These companies are small, and are focused on very specific technologies needed by smallsats to operate efficiently in space. As such, their achievements are generally more mundane and less exciting that a SpaceX Starship/Superheavy test launch, by many magnitudes. Nonetheless, their success, not only technically but financially, suggests a growing maturity to the in-orbit space industry, which will also lay the groundwork for much more sophisticated operations in the future beyond Earth orbit. The people that build these tugs will move on to build vessels that can go to the planets and do things that are presently impossible or too difficult, and do it at low cost and very quickly.

Is the Saxavord spaceport in the UK about to finally get approved for launches?

9:22 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea.

According to the head of the Saxavord spaceport in the UK, it is finally poised to get all the necessary approvals from the government of the United Kingdom that will allow the first launches before the end of this year.

Following on from the CAA licence being granted just before Christmas, management at SaxaVord Spaceport is confident it will receive its ‘range licence’ later this month to finally become a “fully-fledged spaceport”. This second licence, also issued by the Civil Aviation Authority (CAA), allows rockets launched from SaxaVord to use the airspace.

Sounds great, eh? Except that the spaceport is still waiting approval from a local commission of its plan for allowing spectators to watch launches. In addition, no launch license has yet been issued to any rocket company. The German company Rocket Factory Augsburg (RFA) is planning to take over one specific launchpad at Saxavord where it hopes to do as many as ten launches per year, with the first test launch later this year. The UK’s Civil Aviation Authority (CAA) has not yet issued that license.

Another rocket startup, ABL, is also waiting CAA approvals. Its first test launch (which failed in January 2023) was conducted in Alaska, with a second launch planned there in the next month or so. If successful the company hopes to launch regularly from Saxavord, assuming the CAA gives it approval.

Saxavord submitted its license applications to the CAA in November 2022, with the hope launches could begin in 2023. It took the CAA however more than a year to issue the spaceport license, and it still has not issued the range license, nor has it issued RFA any launch licenses yet. For these companies to prosper the government approval process has got to be streamlined.

Harp & VolfgangTwins – Paint It Black

6:01 pm

An evening pause: The music is great, but I generally dislike these music videos that put the performers in some beautiful place that is also a place where it is absolutely impossible to record a performance. They then do lip synch and editing to hide the fact that the performance is faked. Ugh.

Still, as I said, the music is great, and the scenery is beautiful.

Another helicopter mission under development for Mars?

Another helicopter mission for Mars?
Click for original image.

Today’s cool image to the right, cropped to post here, is probably on its own one of the more boring cool images I have posted over the years, a generally featureless plain with some ripple dunes within a few low hollows.

What makes this picture cool however is the label for the image: “Sample Landing and Traverse Hazards at Possible Helicopter Landing Site.” The picture was taken on January 23, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), with the obvious goal of seeing whether this location can serve as a landing site for a helicopter mission to Mars.

The site is relatively uninteresting because the first goal is to find a safe place to land, but to do so near a location where there is rough geology which only a helicopter can explore. And it appears, from the overview map below, that is exactly what this location is.

Amazingly Justice actually charges two leftist activists with felonies for defacing the display case holding the Constitution

12:55 pm

Security guards watch as vandals of the Constitution preach their message
Rotunda security guards do nothing so that these
vandals of the Constitution can preach their message.
Click for video.

In a move that is astonishing considering the political favorism of the left by the Biden administration’s Justice Department, that agency has now charged the two leftist activists who defaced the display case holding the Constitution with felonies.

On Friday, the Department of Justice charged Donald Zepeda of Maryland and Jackson Green of Utah with felony destruction of government property, according to Fox News. Zepeda and Green have been accused of dumping red powder on the case that displayed the historic document. The incident occurred on Feb 14 and the DOJ said their stunt caused more than $50,000 worth of damages.

It is not clear what penalities these two thugs face should they be convicted. For all we know, Justice is merely prosecuting them now for effect, and will allow them to skip with light charges when the case comes to court.

Nor should be we surprised if these vandals end up walking free. » Read more

March 4, 2024 Zimmerman/Space Show podcast

11:14 am

David Livingston has now posted my two-hour appearance on the Space Show last night, with the podcast available for download here.

Despite some technical issues halfway through (which David has edited out of the podcast), the show was fun, especially because of a lot of very good questions from listeners. The second half of the show was devoted to discussing my book Conscious Choice, which David Livingston had read and wanted to highlight. His endorsement of the book was much appreciated. As he noted (I am paraphrasing), it you are interested in the problem of establishing space settlements, you must read this book, because it deals with things beyond engineering that are as if not more important.

Blue Origin is targeting a first unmanned landing of its manned lunar lander in 2025

10:36 am

Blue Origin's Blue Moon manned lunar lander
An early visualization of Blue Moon

According to one Blue Origin official, the company is now targeting its first unmanned landing of its manned lunar lander, Blue Moon, for sometime in 2025, far sooner than previously expected.

Jeff Bezos’ Blue Origin space venture is aiming to send an uncrewed lander to the surface of the moon in the next 12 to 16 months, according to the executive in charge of the development program. John Couluris, senior vice president for lunar permanence at Blue Origin, provided an update on the company’s moon lander program on CBS’ “60 Minutes” news program on Sunday. “We’re expecting to land on the moon between 12 and 16 months from today,” Couluris said. “I understand I’m saying that publicly, but that’s what our team is aiming towards.”

Blue Moon is shown in the graphic to the right. Though being built to provide NASA a second manned lander in addtion to SpaceX’s Starship, this first mission will simply bring cargo to the surface, as a test of the lander itself.

If Blue Origin can keep even somewhat close to this schedule, we will likely have two manned moon landers doing test flights at almost the same time.

A sidebar: Note the lander’s height, as well as the narrow footprint of its landing legs. New graphics of this lander from Blue Origin show the same high center of gravity with an even narrower footprint for the legs. One wonders why. Wouldn’t it make sense to have those legs deploy outward more?

This issue applies also to SpaceX’s Starship, which will also have a high center of gravity. When SpaceX’s rockets land on Earth (both Falcon 9 boosters and Starship), most of their fuel is gone so the bulk of the mass is near the bottom where the engines are, even though the boosters stand very high. On the Moon however these vehicles will be landing heavily loaded, with cargo and fuel. This raises a stability question that was illustrated sadly by the tipping over recently of Intuitive Machines Odysseus lander.

I am not an engineer, so I admit that my off the cuff analysis here is very questionable. Nonetheless, one wonders.

Scientists: Europa produces oxygen on its surface, but less than expected

10:18 am

Graphic of Europa
Click for original image.

The uncertainty of science: Scientists using data from a 2022 flyby of the Jupiter moon Europa by the orbiter Juno have determined that the moon produces about 1,000 tons of oxygen every 24 hours on its surface, a large amount but less than most predictions based on previous indirect observations.

The paper’s authors estimate the amount of oxygen produced to be around 26 pounds every second (12 kilograms per second). Previous estimates range from a few pounds to over 2,000 pounds per second (over 1,000 kilograms per second). Scientists believe that some of the oxygen produced in this manner could work its way into the moon’s subsurface ocean as a possible source of metabolic energy.

You can read the paper here. The graphic shows the basic process, as presently theorized. What remains unknown is how or even if that oxygen is transported downward to the theorized underground ocean of liquid water. That the amount created is on the very low end of previous estimates suggests that there will be less free oxygen to support life in that ocean than expected.

SpaceX almost completes dress rehearsal countdown of Starship/Superheavy

10:02 am

According to a tweet from SpaceX, the company yesterday conduceted a dress rehearsal countdown of Starship/Superheavy, ending the rehearsal at T-10 seconds so that no static fire test of Superheavy’s engines occurred.

Starship completed its rehearsal for launch, loading more than 10 million pounds of propellant on Starship and Super Heavy and taking the flight-like countdown to T-10 seconds.

Prior to all its launches SpaceX routinely does this kind of rehearsal, but always ends them at T-0 and a short engine burst. That it did not do so here suggests either some issue prevented it, or the company was doing tests of its propellant loading procedures. Either way, it is likely another dress rehearsal countdown will be required before the actual test flight can occur.

I also suspect the FAA is involved in this in some way, demanding certain actions by SpaceX before the agency issues the launch license. At the moment there is no word when that license will be issued, though Elon Musk keeps saying on X that it is coming “soon.”

Australian rocket startup gets government approval for its spaceport

9:55 am

Proposed Australian commercial spaceports

The Australian rocket startup Gilmour Space has now received a spaceport licence from the Australian government, allowing launches to occur from its Bowen spaceport on the northeast coast of Australia, as shown on the map to the right.

The company describes the approval from [Ed Husic Federal Minister for Industry and Science], who is also the minister in charge of the Australian Space Agency, as a vote of confidence in Gilmour’s technical capability, paving the way for the launch of Australia’s first sovereign-made rockets, ‘bridging Country to Sky’. Gilmour Space has also secured approval from the Department of Climate Change, Energy, the Environment and Water, enabling the operation of the spaceport at Abbot Point.

Not all is unicorns and rainbows however. First, it appears Gilmour began negotiating for this approval two years ago, so the government took a looong time to say yes. The other spaceport on the map has been awaiting for a launch license for about the same length of time, and has still not gotten it.

Gilmour also wants to do its first test launch of its Eris rocket in the next few months, but it is still awaiting its launch license from the Australian Space Agency. We are therefore about to find out whether Australia’s government can issue that permit in the next few months, or will instead emulate Great Britain, and bog things down with endless red tape.

JPL requests proposals from the private sector for Mars exploration

9:44 am

Capitalism in space: JPL, which is the lead agency running NASA’s very troubled Mars Sample Return (MSR) mission, has now issued a request for proposals from the private sector for doing a variety of Mars missions.

NASA’s Jet Propulsion Laboratory issued a request for proposals Jan. 29 for “commercial service studies” for future robotic Mars mission concepts. The studies, with a value of $200,000 or $300,000, would be carried out over 12 weeks. The studies are intended to examine four specific design reference missions to explore commercial opportunities to support Mars exploration: delivery of small payloads of up to 20 kilograms to Mars orbit, delivery of large payloads of up to 1,250 kilograms to Mars orbit, services to provide high-resolution imaging of the Martian surface and communications relay services between Mars and Earth.

Missions to provide imaging or communications from Mars orbit could quite easily be provided by numerous private companies. Delivering payloads to the Martian service is exactly what SpaceX proposes with Starship, and is also what several lunar lander companies have now been doing.

Up until now, JPL has always built everything in-house, or if it didn’t it designed and managed everything very closely. The result with MSR is a project that is now poorly managed, vastly over budget and behind schedule, and very likely to fail. This proposal suggests JPL is now recognizing that private enterprise might be able to do it better, as NASA has now proven with its shift from being the builder to becoming merely a customer.

If so, this proposal might be indicating the first step at JPL and NASA in imposing a major change in MSR itself, coming as it does just days after the release of an inspector general report about that project’s many problems.

Texas approves SpaceX land swap

9:31 am

Despite a concerted effort by a small group of activists to stop it, the Texas Parks and Wildlife Commission yesterday approved a proposed land swap that would give SpaceX 43 acres of state park land in exchange for receiving 477 acres in a nearby wildlife refuge.

The commission said that the land swap “would create a tenfold return,” allowing the Texas Parks and Wildlife Department to begin planning for a new state park that would give the public access to fishing, kayaking, hiking and other outdoor activities.

…The 43 acres it would give to SpaceX are “noncontiguous,” with the commission noting that most of the acres “do not connect to each other or to areas offering public access at Boca Chica State Park.”

“These smaller, noncontiguous tracts do not provide beach access and are dotted among private properties or immediately adjacent to SpaceX’s facilities, meaning they aren’t readily available for public use and provide less cohesive wildlife habitat than offered by a connected and consistently managed tract of conservation land,” the announcement reads.

The opposition came from the same activist groups that have been attempting by lawfare in every way to shut SpaceX down. They claim in the article at the link that “SpaceX has a history of being a bad neighbor, wreaking havoc on the communities and habitat nearby,” but there is zero evidence of this. Even Fish & Wildlife was forced in its own environmental report to admit that there was no reason to block Starship/Superheavy launches at Boca Chica. And the general community is enthused about the presence of SpaceX because of the billions of dollars of new investment and tens of thousands of new jobs it has brought to the Brownsville region.

These activist groups are simply another visible expression of the irrational hatred the left now holds for Elon Musk, because he has dared defy the left in a number of ways. Sadly, these groups routinely get strong help from every media source (also part of that left), always getting quoted and always getting treated as if they are a major political force in the region, when only a tiny minority in south Texas is on their side.

The beat goes on: SpaceX launches twice today

5:36 pm

UPDATE: This post is changed because I missed an earlier launch today from SpaceX, when it launched 53 payloads, including many smallsats using its Falcon 9 rocket lifting off from Vandenberg in California. It then followed with a successful launch of another 23 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral.

On the Vandenberg launch, the first stage successfully completed its fifth flight, landing back at its landing zone at Vandenberg. In the Cape Canaveral launch, the first stage completed its thirteenth flight. landing on a droneship in the Atlantic.

The leaders in the 2024 launch race:

22 SpaceX
10 China
3 Russia

American private enterprise now leads the entire world combined 25 to 19 in successful launches, while SpaceX now leads the rest of the world, excluding American companies 22 to 19.

Real pushback: Faced with a legal requirement to end its DEI programs, University of Florida shuts them down

12:34 pm

Martin Luther King Jr
A real victory for Martin Luther King Jr

Bring a gun to a knife fight: In the past year there have been a variety of bills in state legislatures attempting to rein in or eliminate the racist Diversity, Equity, and Inclusion (DEI) programs and departments at state universities. Some have been relatively weak feel-good, failure theater efforts, such as those that merely “ban” the teaching of these ideas, something that the leftist academics in charge easily get around by simply renaming the programs.

Other states imposed stronger legislation, threatening to cut the budgets of these colleges if they didn’t eliminate the programs. A few states have actually followed through.

Florida however took the strongest action under the leadership of Governor Ron DeSantis and its Republican controlled state legislature. It passed legislation that not only banned the teaching of these programs, it cut their budgets as well. No threats of budget cuts, the budgets of DEI programs were cut, right off the bat.

The University of Florida on March 1, 2024 demonstrated the effectiveness of this strong action.

A sunflower crater on Mars

11:33 am

Overview map

A sunflower crater on Mars
Click for original image.

Cool image time! The picture to the right, cropped and reduced to post here, was taken on December 17, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the science team labels a “pedestal crater,” a crater that, because the impact smashed the ground to make it more resistent, when the surrounding terrain eroded away it left the crater sitting high and dry.

In this case the crater is only a few feet higher than that surrounding terrain. In fact, though it looks much deeper than the crater to the northeast, both are so shallow that their depth is below the resolution of MRO’s elevation data.

Both craters however suggest the presence of a lot of near surface ice, which is confirmed by overview map above. The rectangle marks the location, inside the 2,000-mile-long northern mid-latitude strip I dub glacier country, as almost every high resolution picture suggests glacial features and near-surface ice. The crater to the northeast appears filled with glacier debris, while the sunflower-shaped apron around the pedestal crater suggests the impact hit soft ice that splashed away and then hardened.

Though this pedestal crater does not appear to sit high above the plain, the rough edges of its apron illustrate the subsequent erosion. The impact likely stripped away the dust/debris layer that protected the glacial and near-surface ice of that splash apron so that sunlight would cause it to sublimate away. Thus we have that knobby surface at the edges.

In the NASA budget now approved, Congress demonstrates once again its utter bankruptcy

9:44 am

Negotiators for both the House and Senate have now released a federal budget for the 2024 fiscal year that includes NASA’s budget, and in doing so clearly illustrates by that NASA budget how utterly incompetent, irresponsible, and useless this Congress continues to be.

First of all, this budget is for this fiscal year, that actually began six months ago in October 2023. That Congress can’t come up with a budget on time has not only become routine, those budgets continue to arrive later and later, or not at all.

The budget itself was an attempt to fix things, because it actually is a detailed budget made up of six appropriation bills that the House began developing last year, rather than a massive omnibus bill that no one had reviewed or read. The goal with each bill was to reduce actual spending across the board — as much as 28.8% — not simply slow the growth of that spending.

However, that effort this year has been a failure. The use of continuing resolutions to keep the government running at previously high levels for the first six months of this fiscal year has largely defeated that effort. Do not expect the budget to shrink in 2024 in any major manner at all.

The budget for NASA also gives us a good window into Congress’s bankruptcy.

Watch video from Varda’s return capsule as its comes back to Earth

9:42 am

I have embedded below video taken from inside the capsule of the commercial startup Varda from its release from the Rocket Lab service module throughout its descent back to Earth.

The capsule had been launched in June 2023, carrying equipment to manufacture HIV drugs in space and then return them to Earth for sale. Even though the company had begun negotiations with the FAA and the Air Force two years prior for landing that capsule in the Air Force’s test range in Utah, those agencies blocked its planned return in the September of 2023, and was only able to do it last month. This mission is demo flight, with three others now scheduled.

For the video, Varda included a window looking up outside the capsule, and a camera to film everything that occurred outside that window during descent, release of parachutes, and impact on the ground. It is quite fascinating, as you can see that the capsule initially tumbles, then as the atmosphere thickens its aerodynamic shape causes it to stablize with its heat shield at its bottom.

German rocket startup ships suborbital test rocket to Australia for launch

9:28 am

The German rocket startup Hyimpulse has now packed its SR75 test rocket for shipment to Australia for a suborbital test flight taking off from Koonibba Test Range on that nation’s southern coast.

The launch at Koonibba will also assist HyImpulse as they continue development of their SL1 Orbital Launcher. The SL1 Orbital Launcher will use ten of the SR75 rocket motors to lift payloads of up to 600kg to low earth orbit and could be launched from the Whalers Way Orbital Launch Complex [part of Koonibba] in the future.

The launch campaign is scheduled to begin from mid-April with both companies targeting a launch at the end of April through to early May subject to regulatory approval. [emphasis mine]

The highlighted phrase immediately raises concerns, as Australia is part of the British Commonwealth, with laws based on Great Britain’s. In Great Britain the red tape from those laws has acted to stymie all launches, destroying one company (Virgin Orbit) and threatening the viability of two spaceports. In Australia there have been indications that such red tape is doing the same to new spaceports on the northern coast. We shall see if that April launch happens. If it is delayed because of “pending regulatory approvals” it will confirm that the Australian government is as much a problem as Great Britain’s.

Hyimpulse is one of three German rocket startups, with Rocket Factory Augburg and Isar Aerospace the other two. It however has been very quiet in the past few years, with the other two companies garnering the most publicity as they prepare for their own first test launches. This story suggests however it might actually be the first to fly, despite the lack of news reports about it.

Lockheed Martin offers to buy startup satellite maker Terran Orbital

9:38 pm

Lockheed Martin now has submitted an offer to buy the startup satellite maker Terran Orbital for $293 million.

Lockheed Martin has submitted a nonbinding offer to buy satellite maker Terran Orbital’s 223 million outstanding shares for $1 each and pay $70 million for its outstanding warrants.

Lockheed Martin also offered to cover about $313 million of the company’s outstanding debt.

Lockheed already owns 28.3% of Terran Orbital, and uses the satellite maker to produce its military satellites, so this deal seems a good fit. It also fits the overall long term strategy of Lockheed, which has been investing in a number of other startups (such as rocket startups Rocket Lab and ABL). The company has clearly seen the future. Rather than continue working like an old-style bloated big space company, it has been using these new companies as models for its future work.

SLIM put back to sleep for second lunar night

3:51 pm

Engineers at Japan’s space agency JAXA have put their SLIM lunar lander back to sleep on February 29, 2024 with the hope it might survive its second night on Moon.

“Although the probability of failure will increase due to repeated severe temperature cycles, SLIM plans to try operation again the next time the sun shines (in late March),” the update from JAXA read, automatically translated from Japanese to English by Google.

Like Intuitive Machines Odysseus lunar lander, SLIM’s overall mission was a success, as it proved it could land automatically within a very small target zone and do so softly enough that it could send back data to Earth. The failures and problems experienced by SLIM, such as having a nozzle fall off causing it land sideways are simply fixes that can be instituted on future missions.

NASA shuts down Goddard $2 billion demo refueling program

3:43 pm

After more than a decade of work and more than $1 billion spent, NASA yesterday shut down a Goddard Space Flight Center program, dubbed On-orbit Servicing, Assembly, and Manufacturing 1 (OSAM-1), that would have attempted to refuel a defunct the Landsat-7 satellite.

This Space News article details the program’s long history:

OSAM-1 started about a decade ago as Restore-L, with the goal of launching as soon as 2020 to refuel Landsat 7. The mission was renamed OSAM-1 in 2020 with the addition of payloads to perform in-space assembly and manufacturing activities.

The mission, though, suffered significant cost overruns and delays. As of April 2022, the mission’s total cost, once projected to be between $626 million and $753 million, had grown to $2.05 billion and its launch delayed to December 2026. NASA’s Office of Inspector General (OIG), in an October 2023 report, concluded the project would likely suffer additional overruns, with an estimated cost at completion as high as $2.17 billion and a launch of between March and June 2027.

The program was originally conceived by Frank “Cepi” Cepollina, who had run the program in the 1980s to use the shuttle and standard parts on satellites to successfully repair the Solar Max satellite, and then headed the program at Goddard that ran all the repair missions to the Hubble Space Telescope. It was his correct contention that designing satellites and spacecraft with standard modular parts would not only allow for replacement and repair, it would reduce the cost of getting into space while increasing increasing profit margins.

The problem was that Cepi’s operation was a government program, divorced from cost controls and profit. Unlike the many private orbital tug companies that are now building and flying the same technology, developed quickly and for relatively little, the Goddard program experienced endless delays and cost overruns. In the end, private enterprise has overtaken the government, and made this program superfluous. Kudos to NASA’s management for making the hard decision to shut it down finally.

Astronomers discover new moons around Neptune and Uranus

8:50 am

Using a observations over several years from a number of ground-based telescopes, astronomers have now identified two new moons around Neptune and one new moon circling Uranus.

The new Uranian member brings the ice giant planet’s total moon count to 28. At only 8 kilometers, it is probably the smallest of Uranus’ moons. It takes 680 days to orbit the planet. Provisionally named S/2023 U1, the new moon will eventually be named after a character from a Shakespeare play, in keeping with the naming conventions for outer Uranian satellites.

…The brighter Neptune moon now has a provisional designation S/2002 N5, is about 23 kilometers in size, and takes almost 9 years to orbit the ice giant. The fainter Neptune moon has a provisional designation S/2021 N1 and is about 14 kilometers with an orbit of almost 27 years. They will both receive permanent names based on the 50 Nereid sea goddesses in Greek mythology.

The two new Neptune moons raises its moon total now to sixteen. The orbits of all three are tilted and eccentric and far from the planets, strongly suggested they are capture asteroids, not objects formed at the same time as the planet.

Local county now in full support of SpaceX land swap

8:41 am

According to a local Cameron county judge, who had previously expressed opposition, county officials including himself are now in full support of the proposed land swap, giving SpaceX 43 acres of Boca Chica State Park land in exchange for 477 acres at a national wildlife area about 10 miles away.

A special meeting of the Texas Parks and Wildlife Commission to vote on this land swap is now scheduled for March 5, 2024 in Austin, and it appears it is ready to approve. That meeting however should be entertaining, because it also appears that the small minority of leftist activists organizations in the area that oppose everything SpaceX is achieving are organizing carpools to attend the meeting. Expect them to perform the typical shennigans of the left, screaming and shouting and attempting to take over the venue to prevent the vote.

What these activists of course refuse to recognize, or simply don’t care, is that the change of opinion by local officials is because the local community and in fact the majority of Texans support what SpaceX is doing. It has revitalized the Brownsville area, bringing billions of new investment capital and tens of thousands of new jobs to the region. It has also demonstrated repeatedly it is being a good steward to the environment at Boca Chica, and will do much as a launch site to help preserve the coastal wildlife there, just as NASA has done at Cape Canaveral for three quarters of a century.
