Academics in space community scheme to continue their racist DEI policies

1:41 pm

USRA logo

A letter sent out yesterday by the Universities Space Research Association (USRA) clearly illustrated the bigoted desire of our modern Marxist academic community to continue its racist Diversity, Equity, and Inclusion (DEI) policies in hiring by hiding or renaming them so that the Trump administration might not notice.

USRA is one of several university consortiums that manage a variety of space, science, and astronomical operations for the government. In USRA’s case, it manages the Lunar Planetary Institute (LPI) for NASA.

The letter purported to announce how the organization was complying with Trump’s executive orders banning such race-based programs, but instead revealed its desire to continue them, but to do so under the table where no one could monitor them.

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

China hints that it is moving forward with expansion of Tiangong-3 space station

12:39 pm

According to a statement by one Chinese official, China will use its Long March 5B rocket to soon launch more modules to its Tiangong-3 space station, expanding the station’s size considerably.

“According to the plan, the Long March 5B rocket will also carry out the future launches of additional modules for the crewed space station,” Wang Jue from China Aerospace Science and Technology Corporation (CASC) told China Central Television (CCTV) April 30. No official timeline has been released for the missions, but the comments appear to confirm plans to add modules to Tiangong, a T-shaped, three-module orbital outpost constructed across 2021-2022.

In 2022 China had hinted on this same plan, but it is three years later and nothing has yet happened. It could be this statement was an attempt at lobbying by this official, trying to convince the government to finance the new modules. Or it could be the first new module, a hub with six docking ports that will allow the additional fullsize modules to be attached, is nearing completion and launch.

Who knows? One must take all such proclamations from China with a grain of salt.

The article also notes the revisions to the Long March 5B rocket so that its core stage no longer reaches orbit to subsequently crash uncontrolled somewhere on Earth. Instead, the upper stage has been upgraded so that it gets the payload into orbit and the core stage shuts down earlier and thus falls into the ocean immediately after launch.

Rocket Lab’s as-yet unlaunched new Neutron rocket gets military contract

10:01 am

Neutron landing platform
Graphic showing Neutron landing on Rocket Lab’s
barge

Capitalism in space: Rocket Lab has won a contract from the Air Force to test the use of its new Neutron rocket for tranporting cargo quickly across the globe, despite the fact that the rocket won’t make its first launch until later this year, at the earliest.

The mission, slated for no earlier than 2026, will fall under the Air Force Research Laboratory’s (AFRL) “rocket cargo” program, which explores how commercial launch vehicles might one day deliver materiel to any point on Earth within hours—a vision akin to airlift logistics via spaceflight.

…The cargo test would be a “survivability experiment.” Neutron is expected to carry a payload that will re-enter Earth’s atmosphere, demonstrating the rocket’s ability to safely transport and deploy cargo.

Neutron is designed to bring its first stage back to a vertical landing on Earth for re-use, similar to what SpaceX does with its Falcon 9. Unlike the Falcon 9, however, Neutron’s fairings remain attached to the rocket, opening and closing like alligator jaws to deploy its satellite payloads. Since it brings the fairing back attached to the rocket and closed after satellite deployment, the plan will be to see if it can carry within this enclosed fairing this Air Force test payload and bring it back unscathed.

This contract suggests the military is very confident that Neutron will fly as planned, and will succeed in its early launches.

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.

Crash prediction for Soviet-era Venus probe narrows

9:36 am

May 9, 2025 morning prediction
Click for original image.

The prediction for when and where a 1972 Soviet-era failed Venus lander will crash back on Earth has now narrowed to an eight hour period on May 10, 2025, centered at 1:54 pm (Eastern).

The map to the right, from the Aerospace Corporation, shows the orbital path of the lander for the Venera lander, covering its last six orbits. Though the center of the prediction would have the lander come down over the Atlantic, that orbit has it crossing parts of South America, all of Europe, much of Asia and India, and Australia.

The lander failed to leave Earth orbit when it was launched in 1972, and has been circling the Earth since. As it was designed to survive the very thick and hot atmosphere of Venus, it is likely to survive re-entry through Earth’s more benign atmosphere.

This prediction will narrow continuously for the rest of the day. I will post an update this evening.

Bright material on the high points of a Martian mountain

12:29 pm

Bright material on top of a Martian mountain
Click for original image.

Today’s cool image is mostly an example of the present unknowns of Mars. The picture to the right, cropped, reduced, and sharpened to post here, was taken on April 2, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The science team quite rightly labels this vaguely as “bright materials,” referring to the bright rim of that crater as well as the scattered bright patches on the surrounding plain. This vagueness tells us that the scientists don’t have enough data yet to definitively identify this stuff, though they know it is distinctly unique because of its inexplicable bright albedo compared to everything around it.

That the crater rim (as well as all the crater rims in the full picture) exhibit this same brightness suggests this material was excavated from below when the impacts hit. The surrounding patches suggest that erosion has exposed this buried material at these points.

Israeli non-profit suspends its effort to build a second Beresheet lunar lander

11:35 am

The Israeli non-profit, SpaceIL, has now suspended its effort to build a second Beresheet lunar lander, citing an inability to raise funds for the project.

SpaceIL had built Beresheet-1, which in 2019 successfully reached lunar orbit, only to crash when it attempted to soft land.

The project’s budget was expected to be similar to that of Beresheet 1, which cost approximately $100 million. Most of the funding came from a group of donors led by Patrick Drahi and Morris Kahn, the primary backer of the original mission. However, in mid-2023, the donor group announced it would no longer support the project. SpaceIL launched an urgent effort to find alternative funding, but the outbreak of war on October 7, 2023, made fundraising even more challenging.

The organization’s board of directors repeatedly extended deadlines to secure funding, but by the final deadline—March 2025—the necessary funds had not been raised, forcing the suspension of the project.

A number of SpaceIL’s engineers on Beresheet-1 left the company after its failure to instead form their own Isreali company that partnered with Firefly to build the successful lunar lander Blue Ghost. I suspect their departure was a major reason why the original investors left, and no others could be found.

SpaceIL continues to do non-profit educational work in Israel. Though it claims its lunar lander project is not dead but merely suspended, it is almost certain it will never fly.

Update on Vast’s space station plans

10:19 am

Haven-2
Haven-2 station once completed

Link here. The article provides a very detailed look at Vast’s short and long range plans, including its overall strategy to win NASA’s full space station construction contract by first building, launching, and occupying its small scale Haven-1 station and thus demonstrating it is the right company for NASA to finance its full scale Haven-2 rotating space station (shown in the graphic to the right).

The article notes that Vast intends to complete Haven-1’s primary structure in July, and do environmental and vibration ground testing from January to March 2026, with its planned launch on a Falcon 9 rocket in May 2026. Once launched it plans to put crews on board for a total of 30-days (though it is unclear at this moment whether that will be a single mission or a series of shorter flights).

In addition, the article reveals that the company also hopes to do two spin tests of Haven-1, testing its ability to rotate and create an artificial gravity. That aligns with the goal of Vast’s full scale Haven-2 station, which it wants to rotate as well. Since the plan is to assembly Haven-2 from upgraded Haven-1 modules, these spin tests are essential for proving the larger station’s design.

Based on this new information, I think we can now map out the evolving but still subject-to-change manned operations at Haven-1, comprising several short 3-5 day manned missions. The first will the crew test the module’s operation. The next two will be to do these spin tests, with people on board.

Vast’s strategy is fundamentally different than the other proposed stations (all listed below). Instead of taking a small NASA development grant to create designs on paper, it is spending its own money to actually launch a demonstration station. If successful, this strategy will make it very easy for NASA to pick it when the time comes to award the larger station construction contracts.

My present rankings for the four proposed commercial stations:

  • Haven-1, being built by Vast, with no NASA funds. The company is moving fast, with Haven-1 to launch and be occupied in 2026 for an estimated 30 days total. It hopes this actual hardware and manned mission will put it in the lead to win NASA’s phase 2 contract, from which it will build its much larger mult-module Haven-2 station..
  • Axiom, being built by Axiom, has launched three tourist flights to ISS, with a fourth scheduled for early June, carrying passengers from India, Hungary, and Poland. Though there have been rumors it has cash flow issues, development of its first module has been proceeding more or less as planned.
  • Starlab, being built by a consortium led by Voyager Space, Airbus, and Northrop Grumman, with an extensive partnership agreement with the European Space Agency. It recently had its station design approved by NASA.
  • Orbital Reef, being built by a consortium led by Blue Origin and Sierra Space. Overall, Blue Origin has built almost nothing, while Sierra Space has successfully tested its inflatable modules, including a full scale version, and appears ready to start building its module for launch.

The French startup, The Exploration Company, ships its next cargo capsule prototype for launch

9:50 am

The Exploration Company, a French startup aiming to provide cargo services to both ISS and the future space stations that will replace it, has completed construction and testing of its next cargo capsule prototype, dubbed “Mission Possible,” and has shipped it to Vandenberg in California for launch on a SpaceX Falcon 9 rocket in June 2025.

In a 6 May update, The Exploration Company announced that it had completed Mission Possible’s pre-shipment review on 2 May and subsequently shipped the capsule to its launch site in the United States. The spacecraft will launch aboard a SpaceX Falcon 9 as part of the Transporter-14 rideshare mission, which is expected to lift off no earlier than June 2025.

Once launched, the Mission Possible capsule will remain attached to the Falcon 9 upper stage until after the stage completes its deorbit burn. This approach is necessary because the capsule lacks sufficient propulsion to independently deorbit itself. After separation, it will carry out a series of reorientation manoeuvres as it begins atmospheric reentry.

This capsule is 2.5 meters in diameter, smaller that its proposed commercial Nyx capsule that is the company’s eventual commercial freighter. It is also larger than the company’s first prototype, which flew on the first launch of Ariane-6 in 2024 but was unable to test its re-entry designs because of a failure in that rocket’s upper stage engine that prevented its planned controlled de-orbit.

Europe and India sign agreement to work together on manned space flight

9:35 am

The European Space Agency (ESA) yesterday announced that it has signed an agreement with the Indian government that will lay the groundwork for them to work together on manned space exploration, first in connection with their future space station plans and later on lunar exploration.

ESA and ISRO declared their intent to work together on the interoperability of rendezvous and docking systems to allow their respective spacecraft to work together in low Earth orbit. They will also examine further activities related to astronaut training, analogue space missions – where teams test aspects of space missions in ground-based simulations – and parabolic flight activities.

…Future cooperation possibilities include ESA astronaut flight opportunities to the planned Bharatiya Antariksh Station (BAS) and early scientific utilisation, as well as developing infrastructure in low Earth orbit. The two space agencies are also discussing alignment on payloads and robotic scientific missions to the Moon.

Faced with the decommissioning of ISS in 2030, as well as the likely end to several major Artemis components (Orion and Lunar Gateway) that ESA has had a major part, it appears Europe has quickly begun looking for other alternatives. It already has partnered with the American consortium building the Starlab space station, but this new agreement with India gives it more options.

India meanwhile gets aid and support from Europe. It could even be that both are negotiating transferring some of Europe’s Lunar Gateway modules to India’s space station.

Russia signs space agreement with Venezuela

9:23 am

The losers unite! Russia’s state-run press today announced that its government have signed a bi-lateral agreement with Venezuela to work together in space.

Moscow and Caracas have agreed to enhance cooperation in the peaceful use of outer space, including by building a Glonass ground station in Venezuela, according to a bilateral cooperation treaty.

Because of the bankruptcy at both nations, this agreement really doesn’t involve much real space development. All it really does is allow Russia to build a ground station in Venezuela for operating its orbiting Glonass GPS-type constellation, which Russia in turn has been struggling for decades to bring back into full operation after the fall of the Soviet Union.

SpaceX gets approval to sell Starlink in India

9:18 am

Almost immediately after India’s government issued this week new tightened regulations for allowing private satellite constellations to sell their services in India, it also apparently completed negotiations with SpaceX to allow it to sell Starlink in India based on these rules.

According to sources, the DoT [Department of Transportation] granted the LoI [Letter of Intent] after Starlink accepted 29 strict security conditions, including requirements for real-time terminal tracking, mandatory local data processing, legal interception capabilities, and localisation of at least 20% of its ground segment infrastructure within the first few years of operation.

Starlink’s nod came amid heightened national security sensitivities, coinciding with India’s pre-dawn Operation Sindoor strikes on terror camps across the border in response to the Pahalgam massacre. However, DoT officials clarified that the decision to approve Starlink was independent of these military developments.

At the moment SpaceX’s chief competitors, OneWeb and Amazon’s Kuiper constellation, have not yet obtained the same permissions. This allows SpaceX to grab a large portion of the market share in India before either of these other companies.

Seepage coming from under an ancient Martian flood lava flow?

12:13 pm

Seepage at edge of lava flow?
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and enhanced to post here, was taken on April 3, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

I have enhanced the image to make it easier to see the details. It appears we are looking at three layers. At the base (on the left side of the picture) is a relatively smooth bottom layer with the highest number of scattered craters. On the top (on the right side of the picture) is a somewhat rough layer with fewer craters.

In between is a middle layer that appears to be seeping out from under the top layer.

The science team seems to agree with my last guess, as they label this image “Possible basal seepage at flow boundary.” The flow boundary is the edge of a lava flood that scientists believe covered a distance of about 1,400 miles at speeds ranging from 10 to 45 miles per hour.

India tightens its satellite regulations for foreign companies

9:27 am

In what is a likely response to the increased military conflict with Pakistan, India’s government has announced new satellite regulations for foreign companies that will likely impact the operations of both Starlink and OneWeb.

The country’s Department of Telecommunications (DoT) announced 29 additional regulations May 5, citing national security interests, which also apply to companies that already hold licenses for providing space-based communication services directly to users.

The rules include a requirement for call logs and other user data to be stored in India, and new obligations for interception and monitoring under national law. Satellite operators must also show how they plan to source at least 20% of their ground infrastructure equipment from India within five years of commercial launch.

The article at the link suggests that these new regulations will have a greater impact on OneWeb than Starlink. Yet, OneWeb already has approval to sell its services in India, while Starlink has not.

The article also included one interesting tidbit from a Starlink official, noting that the company expects to have 6.5 million subscribers by the end of this year. Based on the company’s subscriber fees, that translates into many billions in revenue. Very clearly SpaceX no longer needs NASA to develop Starship.

Ispace’s Resilience lander successfully enters lunar orbit

9:15 am

Map of lunar landing sites
Landing sites for both Firefly’s Blue Ghost and
Ispace’s Resilience

Ispace today announced that its lunar lander Resilience, launched in January by SpaceX, has now been successfully inserted into lunar orbit,

Ispace engineers performed the injection maneuver from the Mission Control Center in Nihonbashi, Tokyo, Japan in accordance with the mission operation plan. The orbital maneuver required a main thruster burn lasting approximately 9 minutes, the longest to date during Mission 2. RESILIENCE is now maintaining a stable attitude in its planned orbit above the lunar surface. Mission operations specialists are now preparing for final orbit maneuvers after reaffirming Ispace’s ability to deliver spacecraft and payloads into lunar orbit. A lunar landing is scheduled for no earlier than June 5, 2025 (UTC) (June 6, 2025, JST).

If all goes right, Resilience will touch down in Mare Frigoris in the northern latitudes of the Moon’s near side, as shown on the map to the right.

This is Ispace’s second attempt to soft land on the Moon. Its first attempt, Hakuto-R1, got within three kilometers of the surface in Atlas Crater (also shown on the map), but then its software mistook its altitude, thinking it was only a few feet above the surface and shut down the engines prematurely, causing it to crash.

This second landing is critical for the company’s future. It has contracts for future landers from both NASA and Japan, but a failure now might cause both governments to reconsider those deals.

NASA cancels VIPER solicitation

9:06 am

NASA today announced that it has canceled its solicitation from the private sector, asking for proposals for launching its overbudget and as yet unfinished lunar rover VIPER to the Moon.

NASA announced Wednesday it is canceling its Lunar Volatiles Science Partnership Announcement for Partnership Proposals solicitation, which sought opportunities to send VIPER to the Moon at no cost to the government.

The announcement, which was very short and lacking in any details, stated also that the agency “will announce a new strategy for VIPER in the future.”

Some background: VIPER was originally budgeted at $250 million. When cancelled in 2024 its budget had ballooned to over $600 million, and that wasn’t enough to complete the rover for launch.

This decision suggests the agency did not get any worthwhile proposals. Apparently, no one was interested in paying the cost to get VIPER finished (about $100 million) and launched. It is also likely that the planned Trump budget cuts had an impact on this decision. NASA management probably recognized that there was no way they could con the administration into forking over any money to finance any private proposal.

It is also possible that this cancellation now is part of the typical game NASA managers always play to get Congress to fund bloated programs like this. Cancel it, get the propaganda press to cry about how the cancellation is so terrible, which in turn gets Congress outraged and willing to approve the extra funds.

Sunspot update: Activity rises slightly in April

1:06 pm

It is the start of the month, so it is of course time for my monthly report on sunspot activity, based on the update that NOAA posts each month to its own graph of sunspots activity. As I have done since the start of Behind the Black in 2010, I take that graph each month and annotate it with extra information to illustrate the larger scientific context.

Sunspot activity in April did nothing to tell us anything about the Sun’s future activity. It rose slightly, but not by enough to suggest that the prediction put forth last month by NOAA scientists that the ramp down to solar minimum has begun is wrong.

FAA approves SpaceX request to increase Starship launch rate at Boca Chica

11:40 am

The FAA today by email announced that it has released the final environmental reassessment that approves SpaceX’s request to increase the number of yearly Starship/Superheavy launches at Boca Chica to as many as 25.

The assessment is now available for public comment, and could still be revised. However, the FAA’s conclusions are clear, as indicated by the highlighted phrase:

The FAA is announcing the availability of the Final Tiered Environmental Assessment and Mitigated Finding of No Significant Impact/Record of Decision (FONSI/ROD) for the SpaceX Starship/Super Heavy Vehicle Increased Cadence at the SpaceX Boca Chica Launch Site in Cameron County, Texas (Final Tiered EA and Mitigated FONSI/ROD).

Under the Proposed Action addressed in the Final Tiered EA, the FAA would modify SpaceX’s existing vehicle operator license to authorize:  Up to 25 annual Starship/Super Heavy orbital launches, including: Up to 25 annual landings of Starship (Second stage); Up to 25 annual landinqgs of Super Heavy (First stage). The Final Tiered EA also addressed vehicle upgrades.

You can read the executive summary of this announcement here [pdf]. The full reassessment can be read here [pdf]. Its conclusion is quite blunt:

The 2022 PEA [Preliminary Environmental Assessment] examined the potential for significant environmental impacts from Starship/Super Heavy launch operations at the Boca Chica Launch Site and defined the regulatory setting for impacts associated with Starship/Super Heavy. The areas evaluated for environmental impacts in this EA [environmental assesssment] included air quality; climate; noise and noise‐compatible land use; visual resources; cultural resources; Department of Transportation Section 4(f); water resources; biological resources (terrestrial and marine wildlife); land use; hazardous materials; natural resources and energy supply; and socioeconomics, and children’s health. In each of these areas, this EA concludes that no significant impacts would occur as a result of SpaceX’s proposed action. [emphasis mine]

As I’ve noted repeatedly, this has all been self-evident for years, as proved by the environmental circumstances at the American spaceports at Cape Canaveral and Kennedy in Florida and Vandenberg in California. Spaceports help the environment by creating large wildlife refuges where no development can occur. We have known this for decades. That the FAA and the federal bureaucracy has in the past five years suddenly begun demanded these long reassessments time after time that simply restate these obvious facts can only be because that bureaucracy wants to justify its useless existence with make-work.

Update on launch schedule for India’s manned space program

10:59 am

According to the head of India’s space agency ISRO, V Narayanan, the first unmanned Gaganyaan orbital mission is now targeting a launch in the last quarter of this year, followed by two more unmanned test flights in 2026 and the manned mission of one to three days flying in the first quarter of 2027.

This schedule appears more firm than any previously announced. When first proposed back in 2018, ISRO’s goal was to launch the first manned mission in 2022. And like all government projects, the launch date kept getting pushed back again and again. ISRO officials will blame the COVID panic for these delays, but that’s hogwash. While ISRO shut down for almost two years out of fear of a only slightly more potent illness than the flu, others did not, and ended up stealing almost all of ISRO’s commercial business as a result.

The delays in Gaganyaan also stem from the unrealistic goals first put forth by ISRO. For example, initially the program did not include these unmanned test flights, a lack that was foolish and later corrected.

Based on all reports in the past year, however, it appears that this newest schedule probably reflects reality, and will take place more or less as described.

Astronomers measure the vibrations of a star 21 light years away

10:22 am

Using an instrument on the ground-based Keck telescope in Hawaii, astronomers have been able to measure the internal vibrations of a star 21 light years away, the equivalent of recording a star’s seismology.

Keck Observatory’s KPF instrument precisely measures the motion of the stellar surface towards and away from the observer. Over four consecutive nights, the team used KPF to collect over 2,000 ultra-precise velocity measurements of the star — enabling them to catch the star’s vibrations in action. This is the first asteroseismic inference of the age and radius for a cool star using KPF.

The astronomers next claim that this data allowed them to date the star’s age as 10.2 billion years old, and that it was about 4% smaller in diameter than measured by other observations. Both these conclusions carry uncertainties, but the former has implications if true for the present theories of stellar evolution, since this star appears to be behaving differently than expected for a star this old.

Astronomers have been doing this kind of stellar seismology for the Sun for several decades. To now have instruments sensitive enough to detect it on stars light years away is truly astonishing.

Stratolaunch completes first hypersonic test flight for Pentagon

9:58 am

The military this week confirmed that Stratolaunch had successfully completed its first two hypersonic test flights for the Pentagon in December and March.

The hypersonic vehicle named Talon A2 exceeded Mach 5—the threshold for hypersonic speed—in two Pentagon-backed test flights conducted in December 2024 and March 2025, the Defense Department confirmed May 5.

The flights mark the first time since the X-15 program, which ended in 1968, that the U.S. has conducted reusable hypersonic testing.

At the moment the military’s hypersonic test program is really getting its money’s worth from private enterprise. Stratolaunch is doing tests using a reusable vehicle. Rocket Lab is doing suborbital flights using a revised version of its Electron rocket’s first stage. Varda will do hypersonic tests with its capsule when it returns from orbit. And startups Ursa Major and Radian have won contracts to do their own test flights.

For literally decades the military’s hypersonic test program had limped along, barely able to do tests more than once every few years. Then however it was run entirely by the government. Now that the military has stopped trying to be the designer and builder but simply a customer, it is getting what it needs fast and with a great deal of variety.

Ain’t freedom and competition and private enterprise wonderful?

Australia’s first rocket company continues to be blocked by red tape

9:40 am

Australian commercial spaceports
Australia’s commercial spaceports. Click for original map.

The first rocket launch by Gilmour Space, Australia’s first rocket company, from its Bowen spaceport on the east coast of Australia has apparently been blocked by continuing bureaucratic regulatory red tape.

In February the company had announced a planned launch date in March, based on what appeared to be the issuance (after more than a year’s delay) of its launch licence. That launch however never happened, with no public explanation, until now. From the link above:

In an update on Sunday, the Queensland-based firm said it had received approval from CASA and is now waiting for final clearance from the Australian Space Agency.

…It had planned for an inaugural blast-off in April 2024 but faced a lengthy delay in obtaining its final permit from the Australian Space Agency.

In other words, the launch license had only been promised, but then was not issued, leaving the company stranded for several more months, with that license still buried in the government’s byzantine operations.

The article at the link says the Australian government is now moving to streamline its space regulatory system, but don’t believe it. The elections this week saw a resounding victory for the leftist coalition with the conservative party defeated handily.
