Satellite companies SES and Intelsat complete their merger

The Luxembourg-based satellite company SES has now completed its acquisition of the European-based satellite company Intelsat, giving the combined company 120 active satellites in a variety of low and high Earth orbits.

With a world-class network including approximately 90 geostationary (GEO), nearly 30 medium earth orbit (MEO) satellites, strategic access to low earth orbit (LEO) satellites, and an extensive ground network, SES can now deliver connectivity solutions utilising complementary spectrum bands including C-, Ku-, Ka-, Military Ka-, X-band, and Ultra High Frequency. The expanded capabilities of the combined company will enable it to deliver premium-quality services and tailored solutions to its customers. The company’s assets and networks, once fully integrated, will put SES in a strong competitive position to better serve the evolving needs of its customers including governments, aviation, maritime, and media across the globe.

Both companies are long established, with Intelsat initially founded in the mid-1960s as a consortium of 23 nations aimed at launching the first geosynchronous communications satellites over the Atlantic and Pacific serving most of the Old World and linked to the New.

The merger is an attempt by both companies to compete with the new low-orbit constellations of SpaceX, Amazon, and from China.

Russia: Commercial satellite constellations providing help to the Ukraine are now targets

Russia this week informed regulators at the International Telecommunications Union (ITU) that it now considers all European and American private satellite constellations “legitimate targets to be destroyed” if they provide any help to the Ukraine.

Russia tells ITU that GPS/Galileo/GNSS nav & commercial broadcast sats helping Ukraine militarily should expect interference. Same for EutelsatGroup, OneWeb, Starlink constellations, which Russia has said are ‘legitimate targets to be destroyed.

There is more at the full article, but that is behind a subscription paywall.

Russia’s announcement here is probably in response to Trump’s more bellicose statements recently about Putin and Russia.

It is hard to predict what will happen, especially when you have a dictator like Putin in power where rational thinking can never be relied on and no laws apply. For example, destroying any orbiting satellites in low Earth orbit will create space junk that will threaten ISS, and a situation NOT beneficial to Russia.

I suspect Russia will begin by trying to jam these constellations. Let us hope it does not go farther than that.

Mars meteorite sells at auction for $5.3 million

The largest Mars meteorite found so far on Earth sold yesterday at auction for $5.3 million, a million dollars more than expected.

The 54-pound (25-kilogram) rock named NWA 16788 was discovered in the Sahara Desert in Niger by a meteorite hunter in November 2023, after having been blown off the surface of Mars by a massive asteroid strike and traveling 140 million miles (225 million kilometers) to Earth, according to Sotheby’s. The estimated sale price before the auction was $2 million to $4 million.

The identity of the buyer was not immediately disclosed. The final bid was $4.3 million. Adding various fees and costs, the official bid price was about $5.3 million.

Most Mars’ meteorites found on Earth are scooped up in Antarctica as part of government funded research. Thus, they are not available for sale. This rock was found by a private meteorite hunter, who then owned the rock free and clear and could do with it as he or she liked. It appears the hunting paid off handsomely.

Axiom’s ticket price for India’s astronaut on Ax-4 mission: $59 million

According to reports today in the India press, the price Axiom charged India’s space agency ISRO for training and then flying its astronaut on the just completed Ax-4 two-week mission to ISS was $59 million.

The expenditure by ISRO includes cost of [Shubhanshu] Shukla’s training for the mission as well as that of a seat on SpaceX’s Dragon spacecraft for the 20-day trip that launched Shukla, and three others — Peggy Whitson from the US, Slawosz Uznanski-Wisniewski of Poland and Tibor Kapu of Hungary — to space.

Earlier reports had suggested Axiom was charging $70 million per ticket. If the $59 million is accurate and applies to the charges Poland and Hungary paid, then Axiom’s revenue for the flight was $177 million. From that it would have to pay SpaceX (for the launch and the use of its Grace capsule) and NASA (for the use of ISS). Based on past history, SpaceX likely charged around $70 million for the launch. The cost for using Grace is unknown. NASA’s fees for a two-week visit to ISS were probably around $10 million plus.

My guess, based on this very limited information, is that Axiom made some profit from the flight, ranging from $20 to $50 million.

Scientists: The Sun’s bright corona acts to impede coronal mass ejections

Using data gathered by the Solar and Heliospheric Observatory (SOHO) since its launch in 1995, scientists have determined that when the Sun’s corona (its atmosphere) is bright, it acts to slow and even block the ejection of coronal mass ejections (CMEs), which if they impact the Earth’s magnetic field can have a harmful effect on our modern technology.

Using data from NRL’s Large Angle and Spectrometric Coronagraph Experiment (LASCO) on board the joint European Space Agency (ESA)-NASA Solar and Heliospheric Observatory (SOHO), the NRL team [National Research Laboratory] compiled nearly three decades of observations of the solar corona. They studied the extensive dataset to investigate trends in the brightness of the Sun’s corona and compare them to CME velocities over the same period. Their study found a strong correlation between the two datasets, with bright regions of the solar corona appearing to relate to substantially slower CME velocities and, in some cases, perhaps entirely precluding CMEs.

This data will help solar weather observers better predict the arrival of CMEs, should they erupt from the Sun aimed at Earth. It will also allow them to gauge the risk of CMEs even occurring.

SpaceX planning to use Starship for manufacturing in space

It appears the enthusiastic investment response last week to the potential of using Varda’s re-turnable capsule for manufacturing in space (especially of pharmceuticals) has caught SpaceX’s interest. According to a news report yesterday, SpaceX has now begun developing a program to use Starship for the same purpose, delivering the raw materials in orbit for short or long periods while these products are produced automatically and then returning them for sale on Earth.

Under the plan, internally called Starfall, SpaceX’s Starship rocket would bring products such as pharmaceutical components to space in small, uncrewed capsules, said one of the people, who spoke on condition of anonymity because the matter is confidential.

Starship would then deploy the capsules, which would spend time in orbit before reentering the atmosphere, where they could be recovered back on Earth, the person added.

This description by this anonymous source seems inaccurate however. Why even consider using these small separate capsules when the entire operation can be put inside Starship, which can then bring everything home when ready? Moreover, Starship’s ability to put a lot of mass in a large space up into orbit gives it an great advantage over the smaller capsules being developed by companies like Varda.

Either way, the advantages of weightlessness for producing products for profit are finally being realized, after decades of blockage by government intransigence. Since the Challenger accident in 1986 and Reagan’s order that the shuttle would no longer not be used for commercial purposes, NASA has forbidden production on its spacecraft and ISS of any products for sale afterward.

Now that the cost of launch has dropped significantly (Thank you Elon Musk!), many investors and companies are seeing great potential for manufacturing in space. And those profits will help feed a private space industry, making the government agency of NASA even more irrelevant.

SpaceX completes its first launch for Amazon

SpaceX tonight successfully launched 24 Kuiper satellites for Amazon’s internet constellation, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage completed its first launch, landing on a drone ship in the Atlantic. This was the third new stage launched in 2025, and follows the company’s recent pattern of launching between one to three new stages per year. The two fairings completed their 27th and 28th flights respectively. As of posting the satellites had not yet been deployed.

This was SpaceX’s first launch for Amazon, out of an initial contract of three launches. The launch was also Amazon’s third Kuiper satellite launch, the previous two by ULA on its Atlas-5 rocket, launching 27 satellites each. While ULA seems poised to begin regular launches for Amazon, having a contract for 46 launches (with completed two), the contracts for Blue Origin’s New Glenn (27 launches, and ArianeGroup’s Ariane-6 (18 launches) are more uncertain. Neither company has achieved any launches on their contracts, and it is not clear when either company, especially Blue Origin, will ever begin regular launches.

This slow launch pace from these companies is a serious problem for Amazon, which is required by its FCC licence to get 1,600 satellites in orbit by July 2026. For this reason, there are rumors that Amazon might switching more launches to SpaceX, as it has the capability of to launch frequently.

We will have to wait and see.

SpaceX now leads the rest of the world in successful launches, 88 to 64.

SpaceX launches 26 Starlink satellites

SpaceX this evening successfully placed another 26 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg in California.

The first stage completed its fourth flight, landing on a drone ship in the Pacific.

The leaders in the 2025 launch race:

SpaceX also has another launch scheduled in just a few hours from Cape Canaveral, launching 24 Kuiper satellites for Amazon. This is SpaceX’s first launch for Amazon, out of contract of three launches. It will also be the third Kuiper satellite launch, the previous two by ULA on its Atlas-5 rocket, launching 27 satellites each.

The failed MethaneSat climate satellite apparently had problems from launch

According to a detailed New Zealand news report today, the failed MethaneSat climate satellite — funded and operated by the Environmental Defense Fund — apparently had significant problems during its short fifteen month life-span, going into safe mode many times, before failing completely last month.

An earlier report from this same news outlet described more fully the issues — which began in September 2024 only about six months after launch.

The mission’s chief scientist has now said more intense solar activity because of a peak in the sun’s magnetic cycle has been causing MethaneSAT to go into safe mode. The satellite has to be carefully restarted every time.

There has also been a problem with one of the satellite’s three thrusters, which maintain its altitude and steer the spacecraft. MethaneSAT says it can operate fully on two thrusters.

It appears there is a lot of unhappiness in New Zealand for spending $32 million on this project that was designed, built, and operated by an environmental activist organization with little space experience.

What is clear now is that the spacecraft likely got relatively little data during its fifteen month life span.

Webb spots aftermath of collision of two galaxies

colliding galaxies
Click for source.

Using the Webb Space Telescope, astronomers have discovered the collision of two spiral galaxies that appears to have caused a supermassive black hole to collapse in its wake.

The Webb false-color infrared image to the right shows the two galaxies as the red dots, both surrounded by a ring, with the supermassive black hole the bluish spot in between but offset somewhat to the left. Follow-up radio observations suggested that this bluish spot was a supermassive black hole, having a mass of a million suns and sucking up matter from the giant gas cloud that surrounds it.

The team proposes that the black hole formed there via the direct collapse of a gas cloud – a process that may explain some of the incredibly massive black holes Webb has found in the early universe.

This hypothesis however has enormous uncertainties, and requires a lot more observations to confirm. The black hole could simply exist unrelated to the galaxy collision, having come there from elsewhere. Or it could be from a third galaxy in this group that these initial observations have not yet detected.

The image however is quite cool.

Axiom’s commercial manned mission to ISS splashes down safely

Axiom’s fourth commercial manned mission to ISS successfully splashed down off the coast of California early this morning, returning its astronaut commander, employed by Axiom, and three government passengers from India, Poland, and Hungary after spending two weeks at the space station and eighteen days total in space.

For all three nations this was their second manned flight, and the first in more than four decades. All three had previously flown astronauts on Soviet era Soyuz missions, with Poland and Hungary’s astronauts visiting the Salyut 6 station in 1978 and 1980 respectively, and India’s astronaut visiting the Salyut 7 station in 1984.

The mission also marked the inaugural flight of SpaceX’s new Grace reusable manned Dragon capsule, the fifth such spacecraft in its fleet. SpaceX’s fleet is now larger that NASA’s space shuttle fleet ever was.

If you watch the live stream at the link, it is once again important to note that everyone you see on the screen, except for these three government astronauts, are employees of SpaceX or Axiom. There is no government involvement at all in the splash down procedure. It is entirely commercial and private affair.

In other words, who needs NASA for spaceflight? It clearly is not required.

A distant globular cluster

A distant globular cluster
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope as part of a research project to study globular clusters in galaxies other than the Milky Way.

The data for this image comes from an observing programme comparing old globular clusters in nearby dwarf galaxies — the LMC [Large Magellanic Cloud], the Small Magellanic Cloud and the Fornax dwarf spheroidal galaxy — to the globular clusters in the Milky Way galaxy. Our galaxy contains over 150 of these old, spherical collections of tightly-bound stars, which have been studied in depth — especially with Hubble Space Telescope images like this one, which show them in previously-unattainable detail. Being very stable and long-lived, they act as galactic time capsules, preserving stars from the earliest stages of a galaxy’s formation.

Astronomers once thought that the stars in a globular cluster all formed together at about the same time, but study of the old globular clusters in our galaxy has uncovered multiple populations of stars with different ages. In order to use globular clusters as historical markers, we must understand how they form and where these stars of varying ages come from. This observing programme examined old globular clusters like NGC 1786 [pictured] in these external galaxies to see if they, too, contain multiple populations of stars. This research can tell us more not only about how the LMC was originally formed, but the Milky Way Galaxy, too.

This cluster, discovered in 1835 by John Herschel, is about 160,000 light years away.

Suborbital test launch from Oman’s Duqm spaceport scrubbed

The Middle East, showing the location of
Oman’s proposed spaceport at Duqm.

A suborbital test launch from Oman’s Duqm spaceport was scrubbed yesterday due to” a technical issue” with the rocket.

DUQM: Etlaq Spaceport’s highly anticipated experimental rocket launch mission “Duqm-2” was aborted due to a technical issue on Sunday, July 13, 2025. Consequently, the launch has been postponed until “a replacement solution is developed,” it stated.

This was the second attempt launch scrubbed at Duqm, officially labeled the Etlaq Spaceport. The first, an attempt by a Middle East startup to do a vertical take-off and landing of a prototype small rocket, was scrubbed in April due to weather and technical issues. No new launch date has been scheduled.

The spaceport had announced in April a schedule of five launches before the end of the year. Two have now been scrubbed. All appear to have major financing from the Oman government. I suspect all have been pushed too hard and too fast by the government for PR reasons, which explains the two scrubs and the lack of a new launch schedule.

Dragon capsule undocks from ISS carrying four Axiom’s passengers

After spending 18 days in space, 14 on ISS, the Dragon capsule early this morning undocked from ISS with a splashdown scheduled for early tomorrow.

The mission was financed by the space station company Axiom, and was commanded by former NASA astronaut Peggy Whitson, now employed by Axiom as a professional astronaut. The three paying passengers were all government astronauts from India, Poland, and Hungary.

The capsule, dubbed Grace, is the newest addition to SpaceX’s fleet of five manned reusable capsules, flying on its first mission.

Splashdown is scheduled for the wee hours of July 15th tomorrow off the coast of California. The live stream can be found here.

SpaceX launches geosynchronous satellite for unnamed customer

SpaceX tonight successfully launched a geosynchronous satellite for unnamed customer, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage completed its thirteenth flight, landing on a drone ship in the Atlantic. The fairings completed their fourteenth and eighteenth flights respectively. No information about the satellite was released, including ending the live stream right after the first stage landed while providing no information about the satellite’s orbit after stage separation.

First suborbital launch of Taiwan rocket startup fails

The first suborbital launch of the Taiwan rocket startup Tispace failed today shortly after lift-off from a new commercial spaceport on the northern island of Hokkaido in Japan.

The rocket took off from Hokkaido Space Port at 11:40 a.m. local time, but it was soon seen drifting, with smoke escaping. Footage of the launch was shown by NHK News on its website.

Nobody was reported injured in the incident, and the rocket was not carrying any payload. The first launch of a foreign-made rocket from Hokkaido served to test its engine’s capabilities, the report said.

The rocket startup was formed in 2016 and originally wanted to launch from Taiwan. After legal issues blocked that launch site it then attempted to arrange a launch from Australia. It appears similar red tape issues forced it to switch to Japan.

Weird drainages on Mars

Weird drainages on Mars

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on Februay 11, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The camera team posted it yesterday as their own cool image, labeling it “A Fissure and Channel near Pavonis Mons”. From the caption:

A linear trough strikes northeast, then abruptly ends (or changes into a narrow ridge). Where the trough ends, a sinuous channel has an east-southeast strike, trending at almost a right angle to the trough. What happened to form these features?

We can speculate that first there was a southwest-to-northeast trending fracture or fault, perhaps associated with a volcanic vent. Groundwater (or some other runny fluid) coursed through the fault until overflowing and forming the sinuous channel. Continued movement through the fault carved a trough up to the overflow point.

The arrows indicate the downhill grades. Though this caption mentions groundwater, it is far more likely that the “runny fluid” was lava, as shown by the overview map below.

Varda raises another $187 million in private investment capital

Click for original image.

The in-space manufacturing startup Varda has now raised another $187 million in private investment capital, bringing the total cash the company has raised to $329 million.

The $187 million fundraise was led by Natural Capital and Shrug Capital, with participation from Founders Fund, Peter Thiel, Khosla Ventures, Caffeinated Capital, Lux Capital, and Also Capital. Since launching their first mission, W-1, in 2023, Varda has completed three successful launch and return missions, with a fourth, W-4, currently in orbit and a fifth expected to launch before the end of the year.

…”With this capital, Varda will continue to increase our flight cadence and build out the pharmaceutical lab that will deliver the world’s first microgravity-enabled drug formulation,” said Varda CEO Will Bruey.

Varda has expanded its footprint terrestrially as well, opening an office in Huntsville, Ala. and a new 10,000 square foot laboratory space in El Segundo, which will allow its pharmaceutical scientists to begin working on developing processes to crystallize biologics, such as monoclonal antibodies. As of 2022, the market size for monoclonal antibodies is estimated to be $210.06 billion.

As I have noted previously, a real market for pharmaceuticals produced in weightlessness has existed for decades. It appears Varda is now well placed to be the first to make money doing so, using its returnable capsules.

One more note: These products and this industry could have been developed on ISS, but NASA has banned all profit-making commercial manufacturing projects there from the station’s beginning. You can do research, but you are forbidden to create any products for sale later on Earth. This strange policy is left over from before the station, when Reagan discontinued all commercial missions on the shuttle following the Challenger accident.

SpaceX gets approval to build oxygen plant at Boca Chica

SpaceX today received the okay from Cameron County to build a plant at Boca Chica to produce oxygen from the atmosphere for use in its Superheavy/Starship rocket.

The commissioners voted, 3-1, to give Elon Musk’s rocket company a beachfront construction certificate and dune protection permit, allowing the company to build a modern-day factory akin to an oil refinery to produce gases needed for space flight launches.

The plant will consist of 20 structures on 1.66 acres. The enclosed site will include a tower that will reach 159 feet, or about 15 stories high, much shorter than the nearby launch tower, which stretches 480 feet high. It is set to be built about 280 feet inland from the line of vegetation, which is where the dunes begin. The factory will separate air into nitrogen and oxygen. SpaceX utilizes liquid oxygen as a propellant and liquid nitrogen for testing and operations.

By having the facility on site, SpaceX hopes to make the delivery of those gases more efficient by eliminating the need to have dozens of trucks deliver them from Brownsville. The company says they need more than 200 trucks of liquid nitrogen and oxygen delivered for each launch, a SpaceX engineer told the county during a meeting last week.

As usual, the same cranks who always complain about this stuff are given space by this news outlet to whine, but the truth is that the commission’s vote well reflects the attitude of the local community. It supports what SpaceX is doing, because of the prosperity the company is bringing to this formerly depressed region.

Moreover, this facility will not only save SpaceX money and make it easier to launch more frequently, it is likely environmentally beneficial. I suspect the facility will be relatively clean compared to the truck convoys it will replace.

Why did Trump suddenly pick Transportation Secretary Sean Duffy to become temporary head of NASA?

The reason for Trump’s sudden decision yesterday to name Transportation Secretary Sean Duffy as interim NASA administrator, replacing long-time NASA manager Janet Piro — who had held the job since Trump took office — remains unclear.

This article suggests the president wanted someone with more political clout who was also part of his inner circle.

Two articles (here and here) imply the decision was related to the recent clashes politically between Trump and Musk, adding that Duffy and Musk have been reported to be in conflict over air traffic controller issues. Picking Duffy thus directly reduces Musk’s influence at NASA.

The truth is that we really don’t know exactly what motives brought Trump to make this appointment. It could be that Trump wants someone in charge who will have the political clout to push through his proposed NASA cuts. It also could be Trump wants someone with that clout to review those cuts and change them.

The bottom line is that NASA remains a political football, a situation that in the end had done decades of harm to the American space industry. The sooner it can be made irrelevant and replaced by a commercial, competitive, and (most important) profitable space industry, the better.

We really don’t need a “space agency.” We didn’t have such a thing when we settled the American west.

SpaceX finally passes final regulatory hurdle to sell Starlink in India

You might get deja-vu from this story, since I have reported repeatedly in the past that SpaceX has finally gotten regulatory approval to sell Starlink in India.

However, India’s complex regulatory framework — leftover from the days of British rule and strengthened for decades after independence when the strongly socialist Congress Party ruled — ended up requiring SpaceX to leap multiple regulatory hurdles to get the Starlink approved. According to news reports today, that last licensing hurdle has now finally been leaped.

The final approval marks a crucial milestone that will pave the way for the Musk-led company to launch its commercial satellite operations in the country. The Elon Musk-led company has been waiting for regulatory approvals since 2022 to operate legally in India. With this approval, Starlink has become the third company to enter the satellite space in India after Reliance Jio and Eutelsat’s OneWeb, in which Bharti Airtel, led by Sunil Mittal, is a shareholder.

Does this mean SpaceX can now sell Starlink in India? Of course not:

The next step for Starlink is to secure spectrum from the government, which will likely be assigned in the coming months. It also needs to set up infrastructure on the ground. One of the most critical aspects of Starlink’s India foray will be its compliance with the country’s security rules.

Since Starlink doesn’t need a complex ground infrastructure, selling terminals directly to customers, the infrastructure mentioned in the quote likely involves partnering Starlink operations with the Indian telecommunications companies Airtell and Jio, so that they get a piece of the action.

New census of inverted channels on Mars strongly suggests the planet once had more water

Martian ridges that imitate rivers
Click for original image.

A new review of inverted channels on Mars now strongly suggests that the red planet was once far wetter than presently seen, with the channels implying the existence of liquid rivers.

The discovery of more than 15,000 kilometres of ancient riverbeds on Mars suggests that the Red Planet may once have been much wetter than previously thought. Researchers looked at fluvial sinuous ridges, also known as inverted channels, across Noachis Terra – a region in Mars’ southern highlands. These are believed to have formed when sediment deposited by rivers hardened and was later exposed as the surrounding material eroded.

Similar ridges have been found across a range of terrains on Mars. Their presence suggests that flowing water was once widespread in this region of Mars, with precipitation being the most likely source of this water.

The image to the right is a good example of an inverted channel, a previous cool image posted in April 2025. It is located not in Noachis Terra but in the northern lowland plains.

The researchers argue that these channels suggest that about 3.7 billion years ago there were flowing liquid rivers on Mars, fed by precipitation. This conclusion however still does not explain how this could happen on a planet that is too cold with too thin an atmosphere for liquid water to exist. Every model so far proposed to make Mars warmer with a thicker atmosphere in the distant past remains questionable with many holes.

Could the inverted channels have been created by glacial activity, ice instead of liquid water? At present we don’t know enough about the Mars environment and the physics of such things in the planet’s one-third gravity to answer that question. It is however a question that scientists I think should be asking, based on the extensive evidence of glacial activity in the Martian mid-latitudes.

The big takeaway from this study however is that it adds weight to the overall trend seen in the data, that over time the total amount of water on the planet has declined. We can see this in glaciers, for example, with later glacial flows always falling short of previous flows. This research shows that even in the dry tropics there was once ample water, even if we don’t yet know what form it took.

Sightseeing near Starship’s candidate Martian landing sites

An interesting mesa near Starship's Martian landing zone
Click for original image.

Today’s cool image takes us sightseeing in the region on Mars that SpaceX has chosen for its prime landing zone for its Starship spaceship. The picture to the right, cropped, reduced, and sharpened to post here, was taken on May 29, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows a 465-foot-high unusually shaped mesa in this region.

The full resolution inset at the bottom of the picture focuses at the strange tilted layers on the southern slope of this mesa. Apparently the layers at this spot were pushed sideways so they lie significantly angled to the horizontal. Though it isn’t clear from this picture, it is possible that the mesa itself is made up of similar tilted layers, hidden below the surface. We can see the tilt only on the mesa’s southern flank because erosion has apparently exposed it.

Note also the black stain that surrounds the mesa. Though this might be caused by wind distributing dust, such stains have also been seen at a location where scientists suspect an inactive hot spring might exist, as well as another location where there may have been relatively recent volcanic activity.

Is this stain caused by any of these processes? In situ exploration would probably be necessary to find out. And we may soon actually have spaceships landing here in the relatively near future with the capability to do this.

ESA tests parachutes and guidance system for its proposed Space Rider reusable mini-shuttle

The engineering
Click for original image.

The European Space Agency (ESA) revealed today that it has completed drop tests from a helicopter of an engineering vehicle of its proposed Space Rider reusable mini-shuttle — similar in concept to the U.S. military’s X-37B — testing the spacecraft’s parachutes and re-entry guidance system.

The drop-test campaign had two objectives: the qualification of the parachutes used to slow the spacecraft during descent, and to test the software that controls the parafoil, guiding the Space Rider’s reentry module to its precise landing site. Space Rider models were dropped from a CH-47 Chinook Italian Army helicopter from altitudes ranging from 1 to 2.5 km, at the Italian military’s training and experimentation area Salto di Quirra.

The press release provides no movie of any of the drop tests, and the images it provides are almost all taken from very far away, making it impossible to see in detail what the engineering vehicle looks like. Only one picture clearly shows it, and that is what I have posted to the right. This is not a model of a spacecraft, but a square box carrying the parachutes and sensors.

Note also that ESA was doing similar drop tests last summer of a similar model. Apparently they aren’t yet ready to test the real thing.

This X-37B copy was first tested by ESA in 2015 and by 2017 the agency was promising it would be flying commercially by 2025. A decade later and they have not yet begun testing a full scale spacecraft. In addition, ESA has established some very complex rules about who can use it commercially, rules so complex I predict few will be interested.

Europe might be trying to adopt capitalism and freedom as its model, but in many ways it behaves as if it hasn’t the foggiest idea what it is doing.

ISRO successfully tests thrusters to be used on its manned Gaganyaan capsule

India’s space agency ISRO last week successfully completed two tests of the attitude control thrusters that will be used on its manned Gaganyaan capsule.

In a statement issued on Wednesday, ISRO said that the short-duration tests, lasting 30 seconds and 100 seconds respectively, were aimed at validating the test article configuration. The space agency stated that the overall performance of the propulsion system during the hot tests had been normal and aligned with pre-test predictions.

It was also noted that during the 100-second test, the simultaneous operation of all Reaction Control System (RCS) thrusters in various modes—both steady state and pulsed—along with all Liquid Apogee Motor (LAM) engines had been successfully demonstrated.

The first unmanned test flight of Gaganyaan is presently targeting a launch in the last quarter of 2025, with two more unmanned test flights in 2026. The manned mission of one to three days would follow in 2027.

Canadian rocket startup hopes to fly first suborbital launch from its proposed Newfoundland spaceport in August

Nordspace's proposed spaceport
Nordspace’s proposed spaceport. Click for original.

Though details remain slim, the Canadian rocket startup Nordspace now says it is targeting an August launch of its hopes to fly first suborbital launch from its proposed spaceport in August.

NordSpace’s Taiga rocket isn’t going to reach orbit when it launches in August, but it’s a big step toward the company’s ultimate goal. Taiga is a small, liquid-fueled, hypersonic launch vehicle capable of carrying just over 110 pounds (50 kilograms) above the Karman Line. This summer’s shakedown cruise will be a low-altitude demonstration of Taiga’s capabilities.

The map to the right indicates the location of the spaceport, near the town of St. Lawrence on the southern coast of the island of Newfoundland.

Whether this launch occurs is very uncertain. For example, a previous report in January 2025 about this launch site suggested that government approvals were still required. It is not known if those approvals have been obtained.

Nordspace is the second company in Canada to propose offering a combined spaceport/rocket service. The other, Maritime Launch Services, first appeared almost a decade ago, but has never gotten off the ground. Nordspace first announced its plans in July 2024, so achieving a first test launch in 2025 will clearly place it ahead of Maritime.

SpaceX gets launch contract from Globalstar

As it appears right now to be the only American rocket company capable of taking on new launch contracts, SpaceX today was awarded a new launch contract from Globalstar to launch its third generation set of satellites.

The press release is not clear about the number of satellites or launches involved, but either way the deal signals SpaceX’s continuing dominance. For larger satellites it has no real competitors. Not only are its launch prices the cheapest, none of its competitors are capable of adding new customers to their launch manifests. In fact, those competitors, ULA, Arianespace, and Blue Origin, are having trouble simply getting their rockets off the ground on a regular basis.

This situation however is likely to change by two years, assuming the new rockets being developed by Rocket Lab, Stoke Space, and Relativity finally begin flying.

Spanish high altitude balloon company to fly tourist flights from South Korea

The Spanish high altitude balloon startup Zero-2-Infinity has now established an office in South Korea with the intention of flying tourist flights from there for a ticket price of about $60k per flight.

Zero 2 Infinity plans to begin its Korean operations with a project called “Byul” — the Korean word for star — which offers a symbolic farewell for pet lovers. The initiative will invite volunteers to send the ashes of their deceased furry companions into the stratosphere, carried in star-shaped, biodegradable capsules. The company aims to begin collecting participants this September, with the first near-space release scheduled for December in Korea.

Byul will apparently be a smaller balloon with no human passengers. The company claims it has already test flown a larger helium balloon with humans aboard to an altitude of 6 miles, and again unmanned to 20 miles. If so it has done so with no publicity at all. This announcement today appears more a push to raise the $70 million the company says it needs to develop this manned balloon capsule.
