South Korea recovers North Korea’s failed spy satellite

9:37 am

South Korea officials have revealed that their salvage operation has recovered the North Korean spy satellite that was lost when its rocket failed during launch on May 31, 2023.

The satellite, known as Malligyong-1, is reported to be designed to take high-resolution images of Earth to provide intelligence for the reclusive country’s military.

Pieces of debris believed to be the Chollima Type 1 rocket used for the mission were recovered just days after the attempted launch, Reuters reported on June 15. South Korea’s Yonhap News Agency is now reporting that the South Korean military has salvaged “an object believed to be a military reconnaissance satellite,” offering a valuable opportunity to learn about the spacecraft and its planned capabilities.

We should not expect South Korea to tell us much of what it finds. I predict the satellite will be very unsophisticated, and to reveal that would not serve the purposes of the South Korean government, which benefits from overstating North Korean military capabilities. North Korea is certainly a threat to South Korea, but all governments always take advantage of such threats to expand their power.

All told South Korea had recovered about 180 pieces of debris, including parts of the failed rocket. The salvage operations are continuing.

Russians launch weather satellite and 42 smallsats

9:29 am

Russians today successfully launched a Russian weather satellite plus 42 smallsats on a Soyuz-2 rocket, lifting off from Vostochny in Russia’s far east.

Almost all of the secondary payloads were Russian. The one exception known was a demo cubesat from the United Arab Emirates (UAE), apparently built by its own engineers and flown to test their growing capabilities. Previous UAE satellites and probes have previously been built by others and used to train UAE engineers.

The leaders in the 2023 launch race:

43 SpaceX
24 China
9 Russia
5 Rocket Lab

American private enterprise now leads China in successful launches 49 to 24 in the national rankings, and the entire world combined 49 to 41, with SpaceX by itself still leading the rest of the world, excluding other American companies, 43 to 41.

The insidious presence of porn in K-12 public schools

1:36 pm

The Harrisonburg school board
The Harrisonburg school board and its superintendent, just one of many
school boards nationwide that have been promoting the queer agenda to little
kids, against the wishes of parents.

In the past three years it has become routine to see stories almost weekly of school board meetings where parents arrive en masse complaining loudly about the pornography they have discovered openly available in school libraries. Similarly, there are numerous other stories of public school teachers and programs eagerly promoting the queer agenda in the classroom, sometimes doing so secretly when faced with parental opposition.

The situation however is far more insidious than suggested by these stories alone. It seems that this issue has been building for a long time, unnoticed by parents and kept quiet by school officials and teachers as they introduced these materials widely in school curriculums and libraries.

For example, why is it that these pornography books, clearly written to appeal to young minds, have appeared so widely in so many schools throughout the nation? The books haven’t just appeared in states controlled by Democrats, but many places, from Florida to Arizona to Georgia to Michigan to Pennsylvania to Maine to Rhode Island to Wisconsin to Virginia. It seems absurdly impossible that so many different and widely spaced school systems would so completely and all at once accept such graphic sexual materials, written for children under twelve.

And yet, these books have been purchased by schools everywhere, in every state in the union. Such widespread eagerness suggests a strong organized effort within the education community to promote the teaching of sex to little kids. This is confirmed by a review of the queer agenda books recommended to teachers and schools by Scholastic, which is one of the main sources for school librarians. From its own webpage, celebrating the queer agenda:

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 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.

A northern lowland ice sheet on Mars?

A northern lowland ice sheet on Mars?
Click for original image.

Cool image time. The picture to the right, cropped to post here, was taken on March 14, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Dubbed simply a “terrain sample,” this image was likely taken not as part of any specific research project, but to fill a gap in the camera’s schedule in order to maintain its temperature by taking regular images. When the camera team needs to do this, they try to find interesting locations not previously photographed. Sometimes the photos turn out somewhat boring. Most of the time however they capture something very intriguing.

In this case, the intriguing feature of this picture is its stippled surface that seems to overlay a relatively flat surface underneath, with some faint covered craters visible. On top are several more recent craters that suggest either the impact landed in very soft material, thus producing little ejecta and no crater rims or the craters are not craters but sinks, places where the ground is subsiding due to some underground process.

Japan’s military tests using Starlink for communications

8:49 am

Japan’s Self-Defense Forces (SDF) have been testing since March the use of SpaceX’s Starlink constellation to augment that nation’s own geosynchronous communications satellites.

Japan’s Defense Ministry signed a contract with an agent that provides SpaceX’s services to equip units of the Air, Ground and Maritime SDF with Starlink antennas and other communication devices. The SDF has been using the service at about 10 locations, including bases and camps, to verify whether there are any operational issues.

The ministry currently has two of its own X-band communication satellites in geostationary orbit about 36,000 kilometers above Earth for SDF units to use. The Starlink deal marks the first time the SDF is using a private-sector satellite constellation in low orbit.

An agreement with another company that provides a similar service will be concluded during the current fiscal year. [emphasis mine]

The goal is to provide Japan redundant communications capabilities in case China or Russia — both of which have become more aggressive militarily in the past few years — attempt to take out its own satellites. The highlighted sentence strongly suggests a deal with OneWeb is also being negotiated.

Webb makes first detection of one particular carbon molecule

8:42 am

The uncertainty of science: Using the Webb Space Telescope, astronomers have made the first detection of methyl cation (pronounced cat-eye-on) (CH3+) in space, located in a baby solar system the star-forming region of the Orion nebula about 1,350 light years away.

While the star in d203-506 is a small red dwarf, the system is bombarded by strong ultraviolet (UV) light from nearby hot, young, massive stars. Scientists believe that most planet-forming disks go through a period of such intense UV radiation, since stars tend to form in groups that often include massive, UV-producing stars.

Typically, UV radiation is expected to destroy complex organic molecules, in which case the discovery of CH3+ might seem to be a surprise. However, the team predicts that UV radiation might actually provide the necessary source of energy for CH3+ to form in the first place. Once formed, it then promotes additional chemical reactions to build more complex carbon molecules.

Broadly, the team notes that the molecules they see in d203-506 are quite different from typical protoplanetary disks. In particular, they could not detect any signs of water. [emphasis mine]

In the next day or so we shall likely see a number of stories in the mainstream press shouting some variation of “Webb finds key element of life!” Webb has done no such thing. It has found a carbon molecule not seen previously, which simply provides scientists another small data point in trying to understand the development of complex solar systems.

The highlighted sentences make clear the uncertainty in this field and the general shallow amount of knowledge. For example, why carbon molecules but no water, which is made up of hydrogen and oxygen, both ubiquitous throughout the universe and found in large amounts in star-forming regions?

Tiny Tim’s first appearance on the Tonight Show with Johnny Carson

6:01 pm

An evening pause: Aired live April 4, 1968. This important moment in time not only illustrates the incredible tolerant and eccentric nature of 1960s culture, it shows us Johnny Carson at his best. He recognizes the eccentricity of his guest, uses it for humor, but then is also sincerely willing to interview Tim and let him express himself. As always, Carson is kind to his guest, which is one of the reasons his audience loved him so much.

Carson also recognized that Tiny Tim’s eccentricity was great entertainment (something Tim recognized himself quite clearly), which is why Carson allowed the appearance to go so long. It was good show business.

Hat tip Judd Clark.

Real pushback: Thirteen university-run child mutilation clinics to shut down this year

1:45 pm

Owned for the purpose of mutilation and castration
Up to now, government-controlled apparently to allow their
mutilation and castration

Bring a gun to a knife fight: Because of pressure from state legislatures, up to thirteen university-run child mutilation clinics — falsely called “gender-affirming clinics” — are to shut down before the end of this year, with more shut downs likely next year as well.

Up to 13 pediatric gender clinics at university hospitals could close or scale back by the end of the year, as a result of Republican-led states restricting doctors from removing healthy organs or injecting hormones into minors who are confused about their gender.

In some cases, university youth gender clinics have already scaled back their operations as a result of state law. Litigation against the legislation could slow down or stop some clinics from closing. However, some are being closed while litigation proceeds.

The closures represent a quick change from just a year ago when The College Fix identified at least thirteen Republican-led states that funded pediatric gender clinics through universities, including Oklahoma, Florida and West Virginia.

Determining whether a Martian crater is impact or volcanic

Determining whether a Martian crater is impact or volcanic
Click for original image.

Overview map

Cool image time! The picture above, rotated, cropped, reduced, and sharpened to post here, was taken on March 22, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The camera team labeled this “Crater rim and ejecta,” which subtly reveals the picture’s scientific purpose.

The white dot on the overview map to the right indicates the location of this 15-mile-wide unnamed crater, about 150 miles northwest of where the rover Opportunity landed and traveled south to the rim of Endeavour Crater. It also shows in the inset that the crater appears to sit in the center of an upraised mound, suggesting it was formed not by impact but by volcanic processes.

This picture however says otherwise. The many small mounds and mesas to the south of the crater rim are not what one would expect on the apron of a volcano. Instead, they suggest this crater is an impact, with those mounds the eroded ejecta from that impact, now also partly buried by dust. This hypothesis is strengthened by the data from Opportunity, which found a great deal of impact ejecta during its travels, possibly from the very event that created this crater.

Three articles today all asked the same question as I pose above in the headline, noting the similarity in the business model of the deepsea tourism company OceanGate Expeditions and the burgeoning space tourism business, including both suborbital and orbital flights.

Without question there will be many more such articles in the coming days, as more information is gathered about what caused the failure of the Titan. As these three articles do, all will note the similarities and differences between deep sea tourism and space tourism.

Rocket Lab to attempt full recovery of first stage on next launch

9:46 am

In announcing the launch window, opening July 14th, for its next New Zealand launch, Rocket Lab also revealed that it will attempt the full recovery of the first stage after it splashes down softly in the ocean using parachutes.

Rocket Lab is also planning to conduct a marine recovery of Electron’s first stage as part of this mission. Rocket Lab’s recovery team will retrieve Electron using a customized vessel and transport the stage back to Rocket Lab’s production complex for analysis. Data from this recovered stage will inform Rocket Lab’s ongoing recovery and reuse program.

The company recently decided to forego any further attempts to snatch the first stage in the air before splashdown using a helicopter. Instead, it thinks it can recover the stage in good enough condition out of the water to use it or its engines again.

The launch itself will carry seven smallsats, four for NASA and three for two commercial companies.

House Democrats propose and Republicans approve Space Force increasing spaceport fees

9:37 am

We’re here to help you! The House Armed Services Committee, controlled by a majority of Republicans, has approved a defense funding bill that includes an amendment, proposed by a Democrat, that would allow the Space Force to charge much larger fees for the use of its spaceports.

Committee members signed off on the legislation June 22, which proposes $874 billion in defense spending. The full House is slated to vote on the bill in July. Included in the bill is an amendment offered by Rep. Salud Carbajal, D-Calif., that would allow the Space Force to collect fees from companies for the indirect costs of using the military’s launch ranges, like overhead infrastructure or other charges that a traditional port authority might impose on its users.

Today, per the Commercial Space Launch Act of 1984, the service is limited to collecting fees for direct costs like electricity at a launch pad. The law also restricts the Space Force from accepting in-kind contributions from commercial companies to upgrade its ranges.

The committee’s bill, if approved, would require commercial launch companies to “reimburse the Department of Defense for such indirect costs as the Secretary concerned considers to be appropriate.”

The bill also includes a Republican amendment that encourages the Space Force to charge other additional fees, or require private companies to do work the Space Force is presently handles.

Though the latter amendment might make sense, both amendments will likely achieve just one thing: making it much more expensive to launch from Cape Canaveral and Vandenberg. Whether those increased costs will be kept as low as possible is entirely unknown. We certainly should not trust officials in the federal government to do so.

Two ultraviolet images of Mars, taken six months apart

9:28 am

Mars in ultraviolet

The two images to the right, rearranged, cropped, and reduced to post here, were taken six months apart by the Mars orbiter MAVEN using its Imaging Ultraviolet Spectrograph (IUVS). From the press release:

The IUVS instrument measures wavelengths between 110 and 340 nanometers, outside the visible spectrum. To make these wavelengths visible to the human eye and easier to interpret, the images are rendered with the varying brightness levels of three ultraviolet wavelength ranges represented as red, green, and blue. In this color scheme, atmospheric ozone appears purple, while clouds and hazes appear white or blue. The surface can appear tan or green, depending on how the images have been optimized to increase contrast and show detail.

The first image [top] was taken in July 2022 during the southern hemisphere’s summer season, which occurs when Mars passes closet to the Sun. The summer season is caused by the tilt of the planet’s rotational axis, similar to seasons on Earth. Argyre Basin, one of Mars’ deepest craters, appears at bottom left filled with atmospheric haze (depicted here as pale pink). The deep canyons of Valles Marineris appear at top left filled with clouds (colored tan in this image). The southern polar ice cap is visible at bottom in white, shrinking from the relative warmth of summer. Southern summer warming and dust storms drive water vapor to very high altitudes, explaining MAVEN’s discovery of enhanced hydrogen loss from Mars at this time of year.

The second image [bottom] is of Mars’ northern hemisphere and was taken in January 2023 after Mars had passed the farthest point in its orbit from the Sun. The rapidly changing seasons in the north polar region cause an abundance of white clouds. The deep canyons of Valles Marineris can be seen in tan at lower left, along with many craters. Ozone, which appears magenta in this UV view, has built up during the northern winter’s chilly polar nights. It is then destroyed in northern spring by chemical reactions with water vapor, which is restricted to low altitudes of the atmosphere at this time of year.

Though of course not visible, the landing sites for Viking-1 (1976), Pathfinder (1997), and Franklin (2028) are captured in the bottom global image, as indicated by the white dots I have added. The two left dots are Viking-1 and Pathfinder respectively, located in the northern lowland plain dubbed Chryse Planitia. Franklin will land to the right, in the transition zone between those northern lowland plains and the southern cratered highlands.

Ariane-6 engineering test rocket at launchpad for engine tests

9:05 am

Ariane-6 test version at launchpad
Click for original image.

An engineering test version of ArianeGroup’s Ariane-6 rocket has arrived at the launchpad in French Guiana, where it will undergo a series of static fire engine and fueling tests.

As seen in this image [to the right] taken on 22 June 2023, the doors of this mobile gantry have been opened and the structure rolled back on rails. The operation, which takes about half an hour, was a trial run in preparation for a series test firings of the Vulcain 2.1 engine. These test firings will be conducted on the launch pad as part of ongoing preparations for the first-ever flight of Ariane 6. Removing the gantry for the first time – and then returning it – also helped validate the Ariane 6 ground infrastructure.

The Ariane 6 rocket visible here is not intended for flight. It is being used to check assembly procedures, electrical and fuel connections, telemetry, etc. Flight models, including the rocket that will make Ariane 6’s inaugural flight, are being built in Europe and integrated by prime contractor Ariane Group. After shipping to French Guiana, Ariane 6 core and upper stages are assembled horizontally, before being transferred to the launch pad and lifted upright inside the gantry, where the solid-fuel boosters and payload are attached. The horizontal assembly method cuts the time and cost of a launch campaign, and is a first for an Ariane rocket.

With only one Ariane-5 rocket launch left on its manifest, the European Space Agency desperately needs to get Ariane-6 off the ground and operational. It was originally supposed to make its first launch in 2020, thus overlapping the final launches of Ariane-5 by several years. At this moment it appears there will be a gap between when one rocket retires and the other begins flying.

SpaceX launches 56 more Starlink satellites

8:45 am

SpaceX this morning successfully launched another 56 Starlink satellites, with its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage completed its eighth flight, landing on its drone ship in the Atlantic. The fairing halves completed their 7th and 10th flights, with the latter a new record.

The leaders in the 2023 launch race remain the same:

43 SpaceX
24 China
8 Russia
5 Rocket Lab

American private enterprise now leads China in successful launches 49 to 24 in the national rankings, and the entire world combined 49 to 40, with SpaceX by itself still leading the rest of the world, excluding other American companies, 43 to 40.

Why is this rare? School board members react in horror when hearing the porn they allow in schools

2:17 pm

Maybe no longer in Brainerd
Maybe the parents of Brainerd have finally decided their children
are theirs, not the government’s

In what seems to be the exception rather than the rule, when parents began reading the pornography that the Brainerd Public school district allowed in its school libraries, the school board members didn’t try to shut them up, but instead were horrified.

When Kevin Boyles, the board chair, attempted to move on from the public comment without addressing the concerns, [D.J.] Dondelinger told him to “hold on a second.” He told Boyles that he would like to make a motion to discuss the book at the next board meeting. “Something needs to be done,” Dondelinger said. “I’m shocked. We need to dig in and find out what the hell’s going on.”

He then proceeded to ask if “this stuff is accessible to fifth graders” and was told by the room of concerned citizens that yes, it was.

Boyles said that they would address the topic at the board’s retreat that took place on June 16, saying that he didn’t think a board meeting was the appropriate venue for a discussion about it initially. “I think it’s fair to say that several of us have questions,” he said.

Dondelinger pushed back, asking for a second to his motion to add the books to the agenda for the next school board meeting, to the applause of the audience.

I have embedded video of this board meeting, cued to when the parents begin reading. If you want to skip listening to badly written porn, Dondelinger’s demand for action begins at the 31 minute point of the video.

Biden administration announces India will sign Artemis Accords

1:08 pm

Modi meeting Biden upon arrival at White House June 21, 2023
Modi meeting Biden upon arrival at White House
on June 21, 2023

As part of the visit of Indian prime minister Narendra Modi to the U.S., the Biden administration today announced that India has agreed to sign Artemis Accords, becoming the 27th nation to join the American space alliance.

It appears India made this decision after the Biden administration agreed to foster a whole range of cooperative technology exchanges.

Cooperation in advanced computing, artificial intelligence, and quantum information science is also being fostered through the establishment of a joint Indo-US quantum coordination mechanism and the signing of an implementation arrangement on artificial intelligence, advanced wireless, and quantum technologies.

Both countries are working together on 5G and 6G technologies, including Open Radio Access Network (RAN) systems, with plans for field trials, rollouts, and scale deployments in both markets. “Here we’ll be announcing partnerships on open ran, field trials and rollouts, including scale deployments in both countries with operators and vendors of both markets. This will involve backing from the US International Development Finance, for cooperation and to promote the deployments in India,” the official said.

The US will support the removal of telecommunications equipment made by untrusted vendors through the US rip and replace program and welcomes Indian participation in this initiative.

The full list of signatories to the Artemis Accords is now as follows: Australia, Bahrain, Brazil, Canada, Columbia, Czech Republic, Ecuador, France, India, Israel, Italy, Japan, Luxembourg, Mexico, New Zealand, Nigeria, Poland, Romania, Rwanda, Saudi Arabia, Singapore, South Korea, Spain, the United Kingdom, the United Arab Emirates, the Ukraine, and the United States.

One would hope that this decision would help separate India from China and Russia, but this is unclear.

There are other questions. » Read more

A spectacular Martian glacier

Overview map

A spectacular Martian glacier
Click for original image.

Mars appears to be a planet filled with past surface flows, none of which are active today but all of which came from widely different geological processes. Yesterday’s Martian cool image showed the hardened remains of a lava flow on Mars. Today’s cool image shows us what might one of the best examples of the kind of glacial evidence orbital images have been finding throughout the mid-latitudes of Mars.

The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on April 27, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The red dot in the inset on the overview map above indicates its location on Mars, in the chaos region dubbed Protonilus Mensae that forms the central part of the 2,000-mile-long Martian region in the north mid-latitudes I dub glacier country. In this region almost every high resolution image shows evidence of glaciers, all protected by a thin layer of dust and debris so they do not sublimate away.

This particular glacier fills a canyon carved into the southern cliff of a mile-high mesa five miles by ten miles in size, and drops dramatically almost 4,700 feet in about four miles. In fact, it so epitomizes what glaciers look like that the camera team for MRO’s high resolution camera used a 2020 image to give a quick lesson on how to spot a glacier on Mars.

This 2023 picture was likely taken as part of a long term monitoring program. Though planetary scientists presently do not think the glaciers on Mars are active and moving, this assumption is not yet confirmed. Taking repeated pictures of this same glacier over time will eventually answer this question.

Update on SpaceX’s work leading to next Starship/Superheavy test launch

10:29 am

Link here. A static fire engine test program has begun for Starship prototype #25, which will fly on top of a Superheavy prototype. Also, work on the launchpad, badly damaged by the first test flight in April, has proceeded quickly.

During the first integrated test flight of Starship, Super Heavy Booster 7’s 30 working engines dug a sizable hole under the OLM [Orbital Launch Mount] during liftoff. The first images of it pictured a dramatic scene and pointed at some tough repair work ahead for SpaceX teams. Over the last two months, the hole was covered and reinforcements have been installed deep into the ground to strengthen the soil.

More recently, teams have been installing several tons of rebar underneath the OLM. While some rebar remains to be installed, as seen from aerial pictures captured by NSF, this work is expected to be finished soon and should be followed by a convoy of concrete trucks to fill up the pit. SpaceX will then install water-cooled steel plates over this concrete which will help support them and serve as an anchor for them.

The update also describes the numerous additional prototypes SpaceX is building at Boca Chica for further flight tests. It also notes this disturbing fact about the company’s planned Starship/Superheavy launch facility in Florida:

Work on the second set of tower sections, chopsticks, carriage system, and QD arm at SpaceX’s Roberts Road facility has come to a halt. Contractor equipment has visibly disappeared and other construction equipment has been removed. The Florida Mega Bay parts have also made their way to Starbase, becoming the second Mega Bay at the Texas facility. The two big cranes that were previously at Roberts Road were also moved to Starbase to aid in the construction of that new Mega Bay.

On top of this, SpaceX has changed the use of the building previously thought to be the factory for Starship sections. This facility is now being used to process Starlink payload integration with Falcon 9’s fairings.

This slow down is probably because NASA has forbidden Starship/Superheavy launches from this launchpad because it is near the launchpad SpaceX uses for NASA’s manned missions. The agency wants SpaceX to be able to launch Dragon from its other more distant pad, and that work needs to be completed first before the Starship/Superheavy pad can be used.

More direct images released of exoplanet 87.5 light years away

9:56 am

Keck images of exoplanet over time

The Keck Observatory in Hawaii has now released its own image of the exoplanet AF Leporis b, following up the images produced by the Very Large Telescope (VLT) released in February.

The direct images Franson’s team captured revealed that AF Lep b is about three times the mass of Jupiter and orbits AF Leporis, a young Sun-like star about 87.5 light-years away. They took a series of deep images of the planet starting in December 2021; two other teams also captured images of the same planet since then.

What make the Keck observations most interesting is that they captured over time the motion of the exoplanet as it orbited its star. The two images to the right show this motion.

The paper, available here, was published today in Astrophysical Journal Letters. This particular star also has a debris disk surrounding it, suggesting it is a young solar system still in the process of forming. From the paper’s conclusion:

AF Lep joins other young planet hosts with debris disks such as β Pic, HR 8799, HD 206893, and HD 95086, reinforcing indications of a higher frequency of long-period planets orbiting stars hosting debris disks.

Startup orbital tug company experiences technical issues on demo flight

9:36 am

The first test rendezvous and docking of two smallsats built by the startup orbital tug company Starfish Space and space station startup Launcher/Vast are facing significant technical issues because both spacecraft are spinning in an unexpected manner.

Soon after Orbiter SN3 separated from the Falcon 9 upper stage, it experienced an anomaly that set it spinning at a rate on the order of one revolution per second, far outside the bounds of normal operating conditions.

By the time Launcher’s team made contact with Orbiter, fuel and power levels were critically low — and the team made an emergency decision to deploy Otter Pup immediately. In a joint statement issued today, Launcher and Starfish Space said that quick action “gave the Otter Pup mission a chance to continue.”

With assistance from Astro Digital and ground station partners, Starfish’s team contacted Otter Pup and determined that it was generating power — but was also spinning because of the circumstances of its emergency deployment.

The plan had been to deploy Otter Pup and have it rendezvous and then dock with Orbiter, demonstrating the maneuverability of both spacecraft as well as their docking equipment. The spinning now threatens the company’s ability to do this. Over the next few months engineers will make attempts to slow the spinning of Orbiter, but it is unlikely a docking can now be attempted.

Intelsat and SES end negotiations to merge

9:27 am

In a very short press release, the Luxembourg-based satellite company SES today announced that it has broken off negotiations to merge with the satellite company Intelsat. The full text:

SES announces today that discussions regarding a possible combination with Intelsat have ceased. On 29 March 2023, SES had confirmed that the company engaged in discussions with Intelsat and that there could be no certainty that a transaction would materialise.

It appears the two companies could not settle differences on a number of points, and according to this article Intelsat decided to end negotiations yesterday.

There has been a trend among the established satellite companies to consolidate and merge, faced with the stiff competition from the new satellite constellations of Starlink and OneWeb. It is very possible that both of these companies will either revisit the idea of this merger, or begin negotiations with other established satellite companies.

In a ceremony yesterday in Washington, Ecuador became the 26th nation to sign the Artemis Accords, a bi-lateral agreement with the United States that was designed during the Trump administration to act as a work around to the limitations to private enterprise in space created by the Outer Space Treaty.

The full list of signatories so far: Australia, Bahrain, Brazil, Canada, Columbia, Czech Republic, Ecuador, France, Israel, Italy, Japan, Luxembourg, Mexico, New Zealand, Nigeria, Poland, Romania, Rwanda, Saudi Arabia, Singapore, South Korea, Spain, the United Kingdom, the United Arab Emirates, the Ukraine, and the United States.

Adding third world nations to the alliance strengthens it, but it is really the clout of major space players like France, Luxembourg, the UK, the UAE, Italy, and Japan that gives the United States a great deal of leverage in establishing future space legal policy, assuming the alliance is used as originally intended. Considering however the Biden administration’s general hostility to the private sector and freedom, it is unclear if that will be the goal.

ULA launches Delta-4 Heavy rocket on next-to-last flight

9:02 am

Early this morning ULA successfully place a National Reconnaissance Office classified surveillance satellite into orbit, using its Delta-4 Heavy rocket lifting off from Cape Canaveral.

This was ULA’s its first launch in 2023. At the start of the year, the company’s manifest listed ten launches. Whether is can complete that manifest in the remaining six months is questionable, considering it has rarely managed a launch pace exceeding one launch per month in its entire history.

This launch was also the next-to-last for the Delta-4 Heavy. ULA is retiring that rocket and replacing it with the still-not-flown Vulcan rocket. The plan had been for there to be an overlap in use as one was retired and the other was initiated. That has not happened.

The leaders in the 2023 launch race remain the same:

42 SpaceX
24 China
8 Russia
5 Rocket Lab

American private enterprise now leads China in successful launches 48 to 24 in the national rankings, and the entire world combined 48 to 40, with SpaceX by itself still leading the rest of the world, excluding other American companies, 42 to 40.
