Blue Origin completes first round of launchpad/New Glenn tanking tests

9:52 am

Link here. In the past week or so Blue Origin has done three tanking tests of its assembled engineering test rocket, simulating fueling of a New Glenn rocket on the launchpad, and now intends to roll that test vehicle back to its rocket assembly building.

From here, it is most likely that the rocket will be prepared for the next round of testing, which will include a static fire of the seven first-stage BE-4 engines. This test will mark the first time that Blue Origin’s BE-4 engines will ignite while integrated with a New Glenn first stage. It will also be the first time that the new launch pad supports an engine firing.

The company continues to aim for a first test launch of New Glenn before the end of the year, and these tests strengthen the likelihood that this schedule is realistic.

UK government to invest £10 million in Saxavord spaceport

9:45 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea.

The government of the United Kingdom announced yesterday that it will directly invest £10 million in the Saxavord spaceport being built on one of the Shetland Islands, as shown on the map to the right.

Coming in addition to around £40 million of private investment, the government funding will allow SaxaVord to accelerate its capital works programme to ensure it is ready to support the first orbital launch.

That capital works program was forced to shut down last year when red tape at the Civil Aviation Authority (CAA) delayed the licensing of Saxavord. It could be this grant has been issued partly to repay the losses the spaceport company experienced due to those bureaucratic delays. The timing kind of reinforces this speculation, as only yesterday Saxavord got its spaceport license approved, though other approvals remain pending.

All this news suggests strongly that the first test flight at Saxavord by the German rocket startup Rocket Factory Augsburg will occur later this year, as promised.

Meanwhile, the other spaceport in Sutherland must be wondering if it can get similar government aid, or if the government is now playing favorites.

Irish company wants to establish spaceport in Ireland

9:32 am

An Irish company, SUAS Aerospace, has announced a investment capital round to raise €5 million in order to establish a spaceport in Ireland by 2027.

The company has been lobbying for this spaceport since at least May 2023. It is based on the southern coast of Ireland at a facility dubbed the National Space Centre. This would likely be close to where the spaceport would be located, though this is unconfirmed.

SUAS Aerospace was founded in 2019 and is supported by the Enterprise Ireland. With initial investment of €1.1 million to date, SUAS has secured significant partnerships with major European Companies including Skyrora, T Minus Engineering, Pangea Aerospace and is part of a successful consortium awarded a €5m grant from Horizon Europe to develop interoperable (plug and play) rocket engine testing infrastructure for Europe.

I wonder if Ireland’s bureaucracy will be easier to work with than Great Britain’s.

SpaceX: We want to fly next Starship/Superheavy test launch on March 14, 2024

9:07 am

In a tweet yesterday SpaceX announced an update on its Starship webpage, outlining its plans for the third orbital test launch of its heavy-lift Starship/Superheavy rocket, with March 14, 2024 listed as the hoped-for launch date.

The update began with these cautionary words, “pending regulatory approval,” and then went on to describe details of the test flight:

The third flight test aims to build on what we’ve learned from previous flights while attempting a number of ambitious objectives, including the successful ascent burn of both stages, opening and closing Starship’s payload door, a propellant transfer demonstration during the upper stage’s coast phase, the first ever re-light of a Raptor engine while in space, and a controlled reentry of Starship. It will also fly a new trajectory, with Starship targeted to splashdown in the Indian Ocean. This new flight path enables us to attempt new techniques like in-space engine burns while maximizing public safety.

I suspect the change in the splashdown location, from northeast of the main island of Hawaii, was instigated by the FAA for those “public safety reasons”. From SpaceX’s perspective, this is an easy give, as a slightly shorter flight makes little difference for this test, and it allows the company to test that Raptor engine by firing that de-orbit burn.

Will the flight occur on March 14th? The odds are high, partly because this SpaceX announcement is designed to put pressure on the bureaucrats at the FAA to finish their paperwork already. At the same time, bureaucrats sometimes love to stick it to private citizens, just for fun. We shall see.

Is this really a spiral galaxy?

10:16 am

Is this really a spiral galaxy?

The uncertainty of science: The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope and released on March 4, 2024 by the PR department of the European Space Agency (ESA) as part of its Hubble Picture of the Week program. It shows what the press release claims is a spiral galaxy about 55 million light years away, seen edge on.

In this image NGC 4423 appears to have quite an irregular, tubular form, so it might be surprising to find out that it is in fact a spiral galaxy. Knowing this, we can make out the denser central bulge of the galaxy, and the less crowded surrounding disc (the part that comprises the spiral arms).

If NGC 4423 were viewed face-on it would resemble the shape that we most associate with spiral galaxies: the spectacular curving arms sweeping out from a bright centre, interspersed with dimmer, darker, less populated regions. But when observing the skies we are constrained by the relative alignments between Earth and the objects that we are observing: we cannot simply reposition Earth so that we can get a better face-on view of NGC 4423!

This picture provides a great example of the amount of assumptions that are often contained in astronomical observations. Though the data strongly suggests this is spiral, we must remember this is merely an educated guess, based on that central bulge and the dust lanes visible along the galaxy’s profile. There is actually no guarantee that this is so. As the press release also notes, astronomers are constrained by our viewpoint, and cannot change that viewpoint to get a better view to confirm this guess. For all we know, a face on veiw of this flat galaxy would reveal it has no spiral arms, but instead is mottled and chaotic, a rare type that does exist.

Astronomers do the best they can, but it is important that they (and we) always recognize the limitations.

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.

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.

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.

SpaceX and China complete launches

10:40 pm

Two successful launches today, first from China and then from SpaceX.

First, China launched what it called a”high-orbit internet services” satellite into orbit, its Long March 3B rocket lifting off from its Xichang spaceport in southwest China. No word where the rocket’s four strap-on boosters or core stage crashed in China.

Then SpaceX launched another 23 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral. The first stage successfully completed its 11th flight, landing on a drone ship in the Atlantic.

The leaders in the 2024 launch race:

19 SpaceX
10 China
3 Russia

American private enterprise still leads the entire world combined 22 to 19 in successful launches, while SpaceX remains tied 19-19 with the rest of the world, excluding American companies.
