Space Force awards SpaceX $2.29 billion contract for military data constellation

9:13 am

In what is intended as an upgrade to the Starshield military variation of SpaceX’s Starlink constellation, the Space Force yesterday awarded SpaceX a $2.29 billion contract to launch a “data transport constellation in low Earth orbit (LEO) for the Space Data Network (SDN), which the service is developing as its central communications network to link sensors to shooters.”

Under the Other Transaction Authority agreement, the company is to deliver “a fully operational prototype capability by the end of 2027,” Space Systems Command (SSC) said in a press release.

The SDN Backbone, formerly known as MILNET and based on SpaceX’s Starshield militarized variant of its commercial Starlink constellation, will serve as the backhaul data transport layer for the broader SDN. While the award to SpaceX is thus not a surprise, the size of the contract is.

It appears that the Pentagon has been so satisfied with its use of both Starlink and Starshield that it was quite willing to give SpaceX this new larger contract.

The good part of this story is that SpaceX is providing good service to the American people, through the Pentagon. The bad part of this story is that it is getting so little competition from the rest of the aerospace industry. This was work that Amazon could have won, had its Leo constellation been operational and competitive. It is not, as yet, and so it loses business. As the saying goes, “He who hesitates is lost.” And sadly a lot of old and even new aerospace companies have been hesitating.

A call to my readers: Find the location of NASA’s lunar base!

8:46 am

Moon base map from NASA's May 26, 2026 presentation

Moon's south pole, with landers indicated
Click for interactive LRO map.

During yesterday’s NASA press conference outlining the first unmanned missions to the agency’s planned moon base near the Moon’s south pole, Carlos García-Galán, Moon Base program executive, included the graphic above of that base in his presentation.

Though García-Galán said this lunar base map is in the south pole region, the map provided no crater names nor any longitude or latitude information. Nor did it provide a scale to determine the size of these craters. Because of this lack of information, I was unable to identify the map’s precise location near the Moon’s south pole, even after searching extensively at the QuickMap site for Lunar Reconnaissance Rover (LRO) images, now managed by Intuitive Machines images and found here. The map to the right was created from that QuickMap site, annotated by me later with the planned landing locations for Chang’e-7 and Griffin, plus the sites where Nova-C and Vikram landed previously.

I am now asking you, my readers, to do some detective work. See if you can pinpoint the location of the map above with the LRO south pole imagery at the link. The crater patterns should provide the first clue. Remember also that the orientation of the map might require significant rotation to match the LRO data. Remember too that the scale of the map above could require you to zoom in a great deal.

If you think you have a match, post it in the comments below.

A review of what happened and what’s next for Starship/Superheavy

8:06 am

Link here. This article is a very nice and thorough review of what happened during SpaceX’s 12th test flight of Starship/Superheavy last week. What I like about it most is that it outlines what happened with very little speculation. No one outside of SpaceX is in a position to do this properly, and some speculation has been I think over the top. The article at the link avoids this.

It also provides a quick and reasonable summary about what is likely to happen next:

Next up will be Booster 20 and Ship 40 for Flight 13. This mission may launch in the July-August timeframe, pending testing and any mitigation efforts relating to the issues found during Flight 12. The launch pad appears to be in good shape, removing it from being a potential bottleneck to Booster 20’s Static Fire test, although that is not expected for weeks.

The article also provided this added news item that SpaceX revealed during last week’s test flight that has mostly fallen under the radar among news outlets (including here):

SpaceX also revealed plans for a lunar Starlink constellation using laser-linked relay satellites and confirmed that Fram2 commander Chun Wang has signed up for Starship’s first crewed interplanetary mission — a two-year Mars flyby. Wang will first fly with Dennis and Akiko Tito on the previously contracted crewed lunar flyby, potentially as early as 2034.

That’s two Starship missions apparently paid for by Wang, one around the Moon followed by a Mars fly-by. With the lunar fly-by targeting 2034, the Mars fly-by is likely a decade away, at the earliest.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

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

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

 

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

 

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

 

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

German rocket startup signs deal with Nova Scotia spaceport

7:50 am

Proposed Canadian spaceports
Proposed Canadian spaceports

The German rocket startup Isar Aerospace, which has not yet had a successful launch, has now signed a launch agreement with Maritime Launch Services, the company that has been trying to create a spaceport in Nova Scotia for more than a decade without success.

Space company Isar Aerospace and Spaceport operator Maritime Launch Services (MLS), have signed a Letter of Intent to advance sovereign orbital launch readiness from Nova Scotia, Canada. The agreement brings together Isar Aerospace’s orbital launch system and MLS’s launch site, Spaceport Nova Scotia, which is strategically located for launches to support reliable access to mid- to high-inclination and polar orbits for Earth observation and communication satellites and constellations, supporting commercial and government missions

Isar’s Spectrum rocket failed seconds after launch in its first attempt in 2025, launching from Norway’s Andoya spaceport. Since January the company has tried again several times but was forced to scrub each time. At present the launch is tentatively scheduled for June.

MLS’s history is even more convoluted. Initially a decade ago it partnered with a Ukrainian rocket company to offer launch services at Spaceport Nova Scotia. After years of delays that deal ended for good when Russia invaded the Ukraine. Since then MLS has tried to interest both satellite and rocket companies, all to no avail. This new deal was probably made possible due to financial help from the Canadian government, which in March 2026 signed a 10 year deal with MLS worth $200 million, with the intent to encourage a “sovereign orbital capability” for Canada. Since there are no rocket companies in Canada capable of doing this, it appears that capability will now come from Germany.

Kansas – Dust in the Wind

6:01 pm

An evening pause: Performed live c2011. While I consider the music of this song truly beautiful, I personally despise the nihilist sentiments of the lyrics. There is more to life and existence than dust and nothingness, even if we as humans can’t quite figure it out. For this reason I have for years refused to post this song as an evening pause when others have suggested it.

I decided this time to finally let it play, mostly because the violin solo here is so well done.

NASA outlines new program of unmanned missions to Moon

2:15 pm

NASA's Moon base plans as of May 2026
NASA’s Moon base plans as of May 2026.

NASA officials today outlined its new reshaped program of unmanned missions to Moon, designed it says to lay the first groundwork for the manned lunar base to follow.

You can watch the press conference here. The map to the right comes from one viewgraph during that conference, and apparently shows the planned lunar base area, which officials said could cover about 100 square miles. Though officials said this is in the south pole region, I have not been able to identify the precise location, using the global map produced by Lunar Reconnaissance Orbiter. The large crater northeast of the base does not appear to be Shackleton Crater.

The schedule includes four already planned missions, two new missions awarded to Blue Origin in a $188 million contract to deliver two new rovers, and a new hopper mission mission to be delivered by Firefly’s Blue Ghost lander. The schedule is as follows:

Colorful Martian dunes

12:00 pm

Colorful Martian dunes
Click for original image.

Cool image time! The picture to the right, cropped to post here, was taken on March 15, 2026 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The science team labels the image a “dune field.” What struck me immediately however was the vast range of colors, something that is usually not seen on Mars. Within a very short distance we go from bright orange to dark blue, with the change sometimes exceedingly sharp.

The orange is likely coarser rocks or bedrock, while the dark blue patches are likely piles of sand that has piled up due to prevailing winds. Why the dunes on the upper plateau change from bright orange to dark blue however is an unknown.

And why the patches of dust remain undefined is also a mystery. Dust on Mars is generally organized into dunes by the wind. It isn’t here.

NASA approves lunar habitation module design from Italy’s space agency

10:06 am

While the American company Redwire appears in the lead to win a European contract to build its lunar lander’s robot arm, it appears the Italian Space Agency (ASI) has gotten NASA’s preliminary approval to begin work on its Multi-purpose Habitation module (MPH) for the lunar base.

The Italian Space Agency [ASI] announced on 22 May that its Multi-Purpose Habitation (MPH) module had been cleared by a NASA review board to progress toward a Preliminary Design Review in 2027. The first MPH module is expected to launch in 2033.

…With the successful completion of the SDR [System Definition Review] and SRR [System Requirements Review], ASI and Thales Alenia Space can now prepare for the Preliminary Design Review (PDR), which will assess whether the module’s preliminary design is mature enough to meet NASA’s requirements before the programme advances into detailed design and hardware development.

It should be noted that the MPH appears to be a revision of the habitable module that ESA and Thales Alenia were building for the now dead Lunar Gateway station. This new deal is likely NASA’s effort to give ESA comparable work to make up for the loss of its Gateway contribution.

At the same time, ASI will face heavy competition from American companies for this work, as it isn’t the only one proposing habitable modules for the American lunar base. In March 2026 Voyager Technologies and Max Space announced a partnership to build their own inflatable habitable lunar modules. Just as ESA can only make rare exceptions when it gives work to American companies, NASA is obliged to do the same with its European contracts.

Redwire completes testing on robot arm prototype for ESA

9:45 am

The European division of the American space manufacturing company Redwire last week delivered to the European Space Agency (ESA) a full developed and tested robot arm prototype, as per a 2024 contract.

The project is being led by Redwire’s Luxembourg team, which recently completed several project milestones including preliminary design and performance assessment.

Before successful delivery, the MANUS Breadboard Model underwent a comprehensive test campaign to verify the functionality and performance of the manipulator and tool-changer subsystems, and to demonstrate operational scenarios aligned with system requirements. All planned operations, including payload handling, end-effector actuation with wireless data and power transfer, range extender manipulation, and automatic deployment, were executed successfully, confirming overall system readiness. Functional testing validated safe and reliable mechanical performance, demonstrating strong joint-space accuracy and stable interaction among subsystems.

The arm is intended for ESA’s Argonaut lunar lander, allowing it to unload cargo from the lander to the lunar surface. ESA’s 2024 development contract was issued to both Redwire and the Polish company PIAP. PIAP however has not even built the actual prototype. It appears ESA is now moving forward on the full contract phase for the entire rover, and it appears Redwire’s Luxembourg division is in the best position to win the robot arm contract portion.

Not surprisingly, Redwire’s stock surged by 24% following this announcement.

Voyager wins $16.5 million DARPA contract to give solid-fueled rockets variable thrust

9:29 am

The space station startup Voyager Technologies announced today that DARPA has awarded it a $16.5 million contract to develop a technology for use by all solid-fueled rocket manufacturers that will allow those rockets to have variable thrust while firing.

Until now, once you light a solid-fueled rocket motor (SRM) it works like a firecracker, burning at the same high thrust until it runs out of fuel. The goal is to introduce ways to change that thrust along the way, if need be.

During the 20-month contract, Voyager will combine its expertise with complex system modeling and controls with the propellant and manufacturing specialized to develop and validate proof-of-concept systems, culminating in tailorable SRM hot-fire demonstrations.

The program also focuses on manufacturing scalability and post-manufacturing control architectures, including the integration of structural health monitoring systems to support real-time health monitoring and performance. These activities are intended to prepare the technology for rapid industrial transition across multiple weapon systems, enabling flexible weapons procurement and large-scale production and stockpiling.

The vagueness in this description likely comes from two reasons. First, the technology is likely difficult and still uncertain. Two, when developed this technology is certainly going to be classified, since solid-fueled rockets are used extensively by the War Department in missiles. It will be made available to multiple American manufacturers, but only to them.

Whether this technology can become operational in less than two years remains a large question. We shall see. Nonetheless, as a company Voyager continues to expand its reach, diversifying its effort beyond its Starlab space station.

An evening pause: For Memorial Day, a repost from 2020. The words:

To fallen soldiers let us sing
Where no rockets fly nor bullets wing
Our broken brothers let us bring
To the Mansions of the Lord
No more bleeding, no more fight
No prayers pleading through the night

Just divine embrace, eternal light

Where no mothers cry and no children weep
We will stand and guard though the angels sleep
Through the ages safely keep

An outcrop of many parallel layers on Mars

An outcrop of many parallel layers on Mars
Click for original image.

Cool image time! The picture to the right, rotated, cropped, and reduced to post here, was taken on March 11, 2026 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The picture has been rotated so that north is to the top.

The science team describes this feature as “dark linear ridges.” Apparently the ground at this location at some point in the past tilted upward, exposing these layers and creating this 250 to 400 foot high escarpment facing south. What makes this even more intriguing is the ground was only uplifted in this one area. If you look at the full image you will see that the surrounding terrain is flat and relatively featureless.

The location is in the high southern latitudes in the Martian cratered highlands. Thus, it is likely that there is some near surface ice in these layers, and in fact the many Martian climate cycles produced by the wide swings in the planet’s rotational tilt likely contributed to making the layers themselves.

The geology of the Moon’s far side, revealed in pictures taken during Artemis-2

9:04 am

A sample of Andrew McCarthy's work
A sample of Andrew McCarthy’s work. Click for original.

When Artemis-2 commander Reid Wiseman took pictures as his Orion capsule swung around the far side of the Moon, he did so as per the instructions of astrophotographer Andrew McCarthy, thus producing enhanced-color photographs capable of distinguishing the lunar geology with more detail.

Astrophotographer Andrew McCarthy is known for turning the moon into something it decidedly isn’t to the naked eye; a colorful, mineral-rich landscape that looks more like a geological survey than the grey orb hanging in the night sky. His technique relies on stacking hundreds or thousands of images together to suppress noise and amplify the subtle spectroscopic differences between different surface materials. The result is both scientifically accurate and visually arresting.
Linking up with Artemis

As Space.com details, just weeks before the Artemis II launch window, McCarthy DM’d mission commander and NASA astronaut Reid Wiseman with a proposal: could Wiseman shoot the moon the same way McCarthy shoots the moon? It turns out he could. “He was immediately onboard,” McCarthy said. “It was a dream come true, obviously, for me, but I saw it as this very unique opportunity.”

McCarthy worked up a plan alongside Wiseman and NASA’s lunar photography team, the same group that had trained the Orion crew on their camera kit. As regular readers will already know, the primary workhorse was a Nikon D5 DSLR paired with an 80–400 mm Nikkor lens, a decade-old body chosen specifically for its exceptional high-ISO performance. Wiseman shot burst sequences at varying exposures throughout the flyby, generating a dataset McCarthy could stack back on Earth.

The picture to the right is a small sample of McCarthy’s work.

NASA practically eliminates any Starliner flights before ISS retires

10:11 am

Starliner docked to ISS
Starliner docked to ISS in 2024.

In a procurement announcement on May 18, 2026, NASA added another three to six crewed flights to ISS to its contract with SpaceX, covering all missions possible through 2030, which in turn practically eliminates the possibility it will buy any manned flights on Boeing’s Starliner capsule.

In a May 18 procurement filing, NASA announced its intent to add six post-certification missions, or PCMs, to SpaceX’s commercial crew contract on a sole-source basis. The agency would order up to three of those missions at the time it added them, formally starting preparations for them.

…Adding six missions to the contract would cover three years of ISS operations, at a rate of one mission every six months. With the currently contracted missions, running through Crew-14, flying through the fall of 2027, the extension would provide coverage through late 2030, when the ISS is slated for retirement. NASA has previously stated the last crewed mission would likely spend a year at the station.

Though it is not stated yet exactly how much SpaceX will earn with these additional missions, based on previous contracts the revenue will likely range from $1 to $2 billion. Overall, SpaceX has probably received somewhere between $4 to $6 billion additional earnings that was supposed to go to Boeing.

Instead, Boeing is now out of the picture entirely, though NASA is being very coy about saying so. It will earn nothing from Starliner, at least in connection with hauling crews or cargo to ISS. And because its contract with NASA was fixed price and the company could not meet its final milestones to get the bulk of its payments, it will have cost the company about $2 billion beyond what NASA had paid it.

It remains unknown whether Boeing wishes to continue the project. NASA officials had suggested earlier this year that it would buy an unmanned cargo mission to ISS to give the company a chance to prove the capsule and get it certified for manned missions. They have since backed off from that plan, scheduling no Boeing missions through the rest of this year.

Though things could still change, it appears Starliner is dead. In history books this Boeing project I think will become the poster boy for the failures of the older big space companies that used to dominate America’s aerospace industry. By the 21st century they didn’t know how to budget, had poor quality control resulting in unreliable products, and designed things that were badly conceived. The result was a bankrupt space industry that was only saved when new companies appeared willing to fill a need these older companies could not.

China launches three astronauts to its Tiangong-3 space station

9:21 am

China today successfully launched three astronauts to its Tiangong-3 space station, its Long March 2F rocket lifting off from its Jiuquan spaceport in northwest China.

The Shenzhou capsule docked with the station 3.5 hours after launch. The overall mission is planned as a standard six-month mission, though depending on how the crew fare one will continue and attempt to complete a yearlong mission.

China’s state-run press provided no information on where the rocket’s lower stages and four strap-on boosters (using extremely toxic hypergolic fuels) crashed inside China. That press however made a big deal about how one of the astronauts comes from Hong Kong, no longer free and now under the full thumb of the communist government.

On the Space Show twice this week!

12:59 pm

After yesterday’s Starship/Superheavy test launch, David Livingston, who runs The Space Show, decided schedule an quick open-lines show for tomorrow, Sunday May 24, 2026 at noon (Pacific), asking all of the show’s board of advisors to come on and discuss their impressions of the launch and the future of SpaceX.

I agreed, mostly because I am curious to hear what the other board members think. They focus more on the engineering than I do, so I want their perspective. I will of course chime in when I think I have something to add.

In addition, I have a full two-hour appearance already scheduled on The Space Show for Tuesday, May 26, 2026 at 6 pm (Pacific). On that show I will expand on my own perspective SpaceX as well as all things related to space exploration, focusing less on engineering and more on the larger political and cultural issues.

In both cases, the shows will be aired live on Zoom. To join that Zoom meeting as a video participant you need to be a supporter of the Space Show by donating at least $100.

However, anyone can listen and participate by phone without donating. To do so you need to email David Livingston at drspace@thespaceshow.com prior to airtime for both the Zoom phone numbers and access permission. The name and the phone number you provide should agree with the same on your telephone number log in when you enter the Zoom waiting room. The Space Show is following Zoom security requirements in inviting public participation in this program.

Without the access codes, you will not be able to join.

You can also place a comment below saying you want to participate, and I will then put you in touch with David.

I hope some of my readers join the discussion. You have a lot to contribute, and you also would ask really pertinent questions.

FAA clears New Glenn for launch

12:18 pm

The Federal Aviation Administration (FAA) yesterday approved the results of Blue Origin’s investigation into the failure of the upper stage of the company’s New Glenn rocket to reach orbit on the rocket’s third launch in April 2026.

The Blue Origin tweet announcing this FAA decision provided little information, saying only this:

The FAA has approved our NG-3 report, and corrective measures have been implemented. Prior to our second GS2 [upper stage] burn, we experienced an off-nominal thermal condition, and, as a result, one of the BE-3U engines didn’t achieve full thrust to reach our target orbit.

Blue Origin says it is preparing for the next New Glenn launch, but provided no information about when. The company is under heavy pressure to up its launch rate, which compared to SpaceX, Rocket Lab, and ULA appears almost pitiful in its slowness. It had had a contract with Amazon to do 27 Leo satellite launches, but that total has been reduced to 24 due to the lack of launches. It is also unable to do any military launches until it flies New Glenn successfully four more times.

Getting New Glenn off the ground successfully and quickly is becoming critical for the company.

One of the three Chinese astronauts to launch this weekend will do a yearlong mission

12:02 pm

The Tiangong-3 station, as presently configured
The Tiangong-3 station, as presently configured,
with two Shenzou capsules docked to its main hub.

Though the decision won’t be made as to who until the mission is ongoing, one of the three Chinese astronauts scheduled to launch this weekend to China’s Tiangong-3 space station will do a yearlong mission, rather than the standard six month missions that they have been doing since the station became operational.

Chinese astronauts Zhu Yangzhu, Zhang Zhiyuan and Li Jiaying (or Lai Ka-ying in Cantonese) will carry out the Shenzhou-23 crewed spaceflight mission. The astronaut selected for the year-long stay will be determined based on how the mission unfolds in orbit, CMSA spokesperson Zhang Jingbo said at a press conference.

During the year-long residency, China will implement its first space-based human body research program to collect crucial data on astronaut exposed to long-duration spaceflight environments, Zhang noted.

I guarantee this is the preliminary to a longer mission that will break the 14.5 month record set by Valeri Polykov on Russia’s Mir station in 1994-95. China’s station program is solid and robust, and even includes plans to double the size of Tiangong-3 in the coming years. There will be nothing preventing them from doing missions even longer, from two to three years, as they develop the knowledge for interplanetary travel.

SpaceX completes a largely successful 12th orbital test flight of Starship/Superheavy

4:41 pm

Starship and Superheavy in flight

SpaceX today successfully completed its 12th orbital test flight of Starship/Superheavy, with Superheavy lifting off and getting Starship into its preliminary flight path and Starship then firing its engines and getting into a workable orbit that naturally decayed over the Indian Ocean.

There were issues with several Raptor-3 engines, being used in flight on both Superheavy and Starship for the first time. During launch one Superheavy Raptor-3 engines cut off prematurely, forcing the other 32 engines to compensate for the loss. Then, after stage separation (shown in the screen capture to the right) Superheavy’s boost back burn cut off prematurely. As a result, the booster did not come down off the coast for a soft vertical splashdown as planned, but came down in the Gulf, mostly uncontrolled. It did successfully fire some engines for the landing burn, but that splashdown was hard.

As for Starship, it also had one engine shut down prematurely, requiring the other five engines to burn about 90 seconds longer to get the ship up to an acceptable orbit. Because of these engine issues, the engineering team decided to forgo a test restart of one Raptor-3 engine.

Starship then successfully deployed 20 dummy Starlink satellites, followed by two operational Starlink satellites that were modified expressly to provide visual observations of Starship and its heat shield while it is space. Only a few minutes later engineers were able to broadcast those observations, showing Starship as seen from nearby.

Starship then successfully executed its planned maneuver leading to a soft splashdown in the Indian Ocean.

Overall this sets the stage for a quick follow-up. Expect new test flights over the summer and fall, coming almost monthly. The company has made it clear it wants to do a two-week refueling mission with two Starship before the end of the year, as well as begin using Starship to deploy the bigger upgraded Starlink version 3 satellites.

Though this flight did not complete a full orbit, the rocket got Starship into an acceptable orbital path, allowing it to do most of the orbital testing desired. I consider this a success for the 2026 launch race:

60 SpaceX
28 China
8 Russia

Isaacman rearranges the deck chairs on the Titanic of NASA

12:50 pm

NASA administrator Jared Isaacman today announced major bureaucratic changes at NASA designed to make the agency’s work more “mission centric”, to use his words.

To improve our operational efficiency, we must evolve the organization to be more ‘mission centric’, with specialized centers properly resourced to support current and future requirements. To do this, we will separate lines of authority between preparing and supporting the workforce and executing the mission.

Center Directors will continue reporting to the Associate Administrator, focused on empowering the workforce and maintaining the facilities and critical capabilities at their Centers. Mission Directorates will now report to the Administrator with the primary focus on leveraging Center resources, industry, and international contributions to execute on the mission as urgently and efficiently as possible. We will also take this opportunity, where appropriate, to consolidate departments, flatten org structure and enhance HQ by rotating operational expertise into critical functions.

Isaacman’s memo is long, and involves a lot of reshaping, including an attempt to give specific research focus to each of NASA’s existing centers, while consolidating several departments at NASA headquarters to make operations more efficient. A good summary can also be found here.

Overall, Isaacman’s changes seem logical and smart. At the same time, I’ve seen new NASA administrators do the same time after time, without actually accomplishing any real change. In a sense this is no different than rearranging the deck chairs on the Titanic as it sinks. You aren’t really fixing the problem, you are making believe you are doing so.

To really fix NASA will require major cuts, with whole centers and bureaucracies eliminated. If NASA is going to depend on the private sector to get things done — which is very clearly doing at this point — it doesn’t need its present large labor force. All it needs is a trim small bureaucracy in Washington to manage the contracts it hands out as it lets the commercial industry develop and build the rockets, spacecraft, and interplanetary bases the U.S. requires.

Isaacman is not willing or able to do this, however. He might want to (though nothing he has said suggests he does) but even if he did Congress will not let him. It wants NASA funded to keep those pork-laden unproductive jobs alive in their numerous congressional districts.

And so, the deck chairs get rearranged.

Watching SpaceX’s 12th Starship/Superheavy orbital test flight

9:59 am

After yesterday’s scrub, SpaceX has now rescheduled the 12th test orbital launch of Starship/Superheavy for later today, with a launch window opening at 5:30 pm (Central).

The upcoming flight will debut the next generation Starship and Super Heavy vehicles, powered by the next evolution of the Raptor engine and launching from a newly designed pad at Starbase.

The flight test’s primary goal will be to demonstrate each of these new pieces in the flight environment for the first time, with each element of the Starship architecture featuring significant redesigns to enable full and rapid reuse that incorporate learnings from years of development and test.

I have once again embedded below several different live streams of the flight.
