Cool image time! The panorama above was created from three pictures taken on June 12, 2026 by the left navigation camera on the Mars rover Curiosity (see here, here, and here). It shows the immediate ground uphill in front of the rover, which appears to be the smoothest ground that Curiosity has seen in about five years, since it entered the foothills at the base of Mount Sharp in 2021.

Since then the terrain has been routinely boulder strewn. In one case, the ground was so rocky and rough that the science team had to back off from their original plans and find a different route.

The panorama above shows something wholly different, a patch of relatively smooth ground with only a scattering of sharp rocks protruding periodically from below. This ground is likely the rover’s first taste of what the science team calls the “yardang unit”, the light colored hills in the lower right of the overview map to the right. For years that team has looked at those hills, wondering what it would be like to drive Curiosity on them. Their geology suggests a much softer terrain, sand shaped into dunes (yardangs) by the wind. The unknown was always whether the ground was structurally strong enough for the rover to traverse it.

It looks like they are about to get their first clue. Based on the panorama above, the ground appears very promising.

On the overview map, the blue dot marks Curiosity’s present position, with the red-dotted line is planned route and white-dotted line its actual travels. The yellow lines indicate approximately the area covered by the panorama.

SpaceX gets an additional $10 billion from its IPO, bringing total raised to $85.7 billion

9:05 am

SpaceX logo

SpaceX yesterday announced that it has raised an additional $10 billion from its initial public offering (IPO) because its original private investors have decided to exercise their option to purchase stock, bringing the total raised to $85.7 billion.

Space Exploration Technologies Corp. (“SpaceX”) today announced the closing of its initial public offering of an aggregate 638,888,888 shares of its Class A common stock, including the full exercise by the underwriters of their overallotment option to purchase an additional 83,333,333 shares of Class A common stock from SpaceX. The issuance of all shares closed on June 15, 2026, bringing the gross proceeds from the initial public offering to SpaceX to approximately $85.7 billion. The shares of Class A common stock began trading on the Nasdaq Global Select Market and Nasdaq Texas on June 12, 2026, under the ticker symbol “SPCX.”

Goldman Sachs & Co. LLC, Morgan Stanley, BofA Securities, Citigroup, J.P. Morgan, Barclays, Deutsche Bank Securities, RBC Capital Markets, UBS Investment Bank, and Wells Fargo Securities acted as book-running managers for the offering. Cantor, Needham & Company, Raymond James, Societe Generale, Stifel, William Blair, BTG Pactual, ING, Macquarie Capital (USA) Inc., Mirae Asset Securities, Mizuho, and Santander acted as co-managers.

The actual cash raised for the company is less than $85.7 billion, as the various financial institutions listed in the second paragraph above get a cut for managing the IPO, which is only 0.75%, the lowest percentage for an IPO since 2010. Thus, SpaceX raised more than $85 billion for its own use.

As I noted a few days ago, this nest egg of cash is only part of the company’s resources. It presently earns about $31 billion in revenue yearly from Starlink and its computer hardware divisions. That number is also certain to rise in the coming years.

Meanwhile, subsequent trading of the company’s stock on Wall Street remains brisk, with the price continuing to rise. It is presently trading at over $200 per share. Though this higher price doesn’t mean more money to SpaceX (as it only represents resales of the stock), it does tell us that the market considers the stock more valuable than its initial price. Thus, the predictions of many financial experts that the IPO was over-valued are so far turning out to be wrong.

Are the Russians no longer going to dock to its leaking Zvezda module on ISS?

10:15 am

Zvezda module of ISS
The Zvezda module, with aft PrK section indicated
where the cracks have been found.

In a report today at Ars Technica, Eric Berger cites two anonymous NASA officials as saying that the Russians have decided to decommission the aft PrK section of its Zvezda module where it has found numerous cracks and air leaks in the hull, apparently caused by the stress of the many dockings to Zvezda since it was launched almost thirty years ago.

Berger’s report was aimed at providing more information about the kerfuffle between NASA and Roscosmos on June 5, 2026,, when NASA had the astronauts on its half of the station shelter inside their Dragon capsule because Roscosmos was going to have its Russian astronauts cut off a structural bracket in Zvezda as part of the first phase of a new leak patch effort. NASA objected strongly to this action, fearing justifiably that the work could cause a catastrophic failure in Zvezda.

The Russians eventually backed off, merely doing measurements of the module’s new crack, which appearantly appeared after a Progress docking in April

Berger doesn’t really add any significant new details to this June 5 story, but he ends his report with this tidbit:

In the days since, there has been some additional back-and-forth, but Russia has now told NASA it will decommission the PrK module. Effectively, this means cosmonauts will no longer enter the PrK module or attempt to pressurize it. Progress vehicles will still be able to use the docking port to transfer fluids or perform other functions, but Russia will need to use other ports to move supplies on board the space station. [emphasis mine]

This quote however doesn’t tell us anything, and actually raises more questions. The Russians have already been keeping the hatch to Zvezda closed as much as possible, opening it only to unload Progress cargo. And if Progress freighters are still going to dock to Zvezda to “transfer fluids or perform other functions”, the module isn’t decommissioned. Nor is the risk reduced. One of the reasons Zvezda has been stressed over the years is that this port is along the station’s main axis, which makes it ideal for engine burns to raise the station’s orbit. Progresses have been doing this repeatedly from Zvezda for three decades. If they intend to dock with Zvezda to “transfer” fluids”, that also suggests they also plan to continue to use that port for those burns.

It also makes no sense to say other ports will be used to “move supplies” from freighters. Russia isn’t going to dock to Zvezda to transfer fluids, do engine burns, and then move Progress to a different port to transfer cargo.

Thus, we really at this moment do not know what the Russians intend. Nor do we know if they plan to continue to dock with Zvezda. And it appears that each time they do, the chances of a catastrophic failure of Zvezda increases.

Two launches so far today, with a third only hours away

9:29 am

Since last night there were two launches globally, by China and SpaceX, with a third launch scheduled several hours hence by the rocket startup Isar Aerospace.

First, China’s launched eight classified “high-resolution optical remote sensing” satellites, its solid-fueled Kinetica-1 rocket (also called Lijian-1) lifting off from its Jiuquan spaceport in northwest China. Such satellites are almost certainly for military reconnaissance. China’s state-run press provided no other information, nor did it mention where the rocket’s lower stages crashed inside China. Kinetica-1 is also built by the pseudo-company CAS-Space, which happens to be wholly owned by a government agency.

Next, SpaceX launched 24 more Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California. The first stage completed its 14th flight (45 days after its previous flight), landing on a drone ship in the Pacific.

Finally, a third launch is scheduled for 1 pm (Pacific) by the rocket startup Isar Aerospace. It will be making its second attempt from Norway’s Andoya spaceport to launch its Spectrum rocket, the first having failed seconds after launch in March 2025. I have embedded the live stream below, and will post a separate report after the launch. UPDATE: Scrubbed due to ground issues.

The leaders in the 2026 launch race (prior to Isar’s launch attempt):

71 SpaceX
37 China
8 Russia
8 Rocket Lab (plus two suborbital HASTE launches)

For the third straight year SpaceX leads the entire world combined in total launches, 71 to 64.

India won’t reveal the cause of its two PSLV rocket failures

10:19 am

India's space agency ISRO, as transparent as mud
India’s space agency ISRO,
as transparent as mud

Though one of India’s high government officials yesterday announced that its space agency ISRO had “resolved” the third stage issue that caused two consecutive failures of its PSLV rocket, that official also refused to provide any details.

Union Minister of State for Science and Technology Jitendra Singh on Saturday said that the anomaly in the Polar Satellite Launch Vehicle (PSLV) has been resolved. Dr. Singh said on the sidelines of the Research, Industry, Start-up and Entrepreneurship (RISE) Conclave 2026 in Bengaluru, that the national level expert committee constituted to review the reason for anomaly in PSLV Vehicle has submitted its report and the anomaly has been detected.

“The report has come out and the anomaly has been detected. However we cannot share that (reason for the anomaly) on a public platform. But experts are working on it, which has been resolved and very soon we will be back on the track,” Dr. Singh said replying to a query by The Hindu.

Note that after the first third stage failure in 2025, ISRO was also reticent about revealing the problem and how it fixed it. Then the third stage failed again at almost the exact same moment during the next launch in January 2026.

A month later this same official announced ISRO knew what the problem was and had fixed it — once again giving no details — and said the next launch was scheduled for June 2026. It is now June, and despite Singh’s promise no PSLV launch is being prepared.

This lack of transparancy speaks very badly for ISRO. It will make it extremely difficult for it to attract any commercial customers. In fact, that is basically what has happened. Before the Covid panic ISRO had a decent share of the commercial satellite market. Now, even with that satellite market growing in leaps and bounds, it has almost no commercial customers.

SpaceX’s IPO sets the stage for the colonization of the solar system — by private enterprise

1:01 pm

Elon Musk during the IPO
Elon Musk at the IPO opening.

While most news reports have focused trivially on Elon Musk’s status as the first trillionaire resulting from SpaceX’s successful initial public offering (IPO) last week, the real story of that IPO has to do with SpaceX itself and how that company’s extremely bright future is going to change human history.

Let me run some numbers.

The day’s earnings

First, the IPO was designed to raise capital for SpaceX by selling about 555 million shares of stock, with an opening price of $135. Once IPO opened however that price immediately jumped to $150, rising as high as $176 during the day, and by closing time settled at $160.95.

If we pick a conservative average sale price of $155 per share, this means SpaceX raised more than $86 billion in investment capital on this one day. The actual number will be less, because the brokerage houses that ran the IPO get a cut, but I would guess SpaceX will walk away with at least $75 billion once all accounts are settled.

To give this some context, NASA’s annual budget for the past two decades has been around $24 billion. NASA however cannot use that cash very efficiently, because it is required by Congress to have a huge unneeded labor force in many centers scattered around the country, to create jobs in specific congressional districts and states.

SpaceX doesn’t have that problem. For the company, this is real money. It can focus its use very precisely and efficiently for what needs to be done, and thus get a lot more bang out of the buck.

Annual earnings

SpaceX however is not limited to just the capital raised in the IPO.

A galaxy as seen by Hubble and Webb

9:23 am

A galaxy seen by Hubble and Webb
Click for original image.

Cool image time. The picture to the right, cropped and reduced to post here, was taken on March 20, 2026 in a coordinated observations by both the Hubble and Webb space telescopes.

This March 20, 2026, image of Messier 64, or the Black Eye Galaxy, is a composite view from NASA’s Hubble Space Telescope and James Webb Space Telescope. It shows Messier 64 captured at near- and mid-infrared wavelengths by Webb, while Hubble’s image shows the galaxy in ultraviolet, visible, and near-infrared light.

Messier 64 is characterized by its bizarre internal motion. The gas in the outer regions of this spiral galaxy is rotating in the opposite direction from the gas and stars in its inner regions. This strange behavior may be the result of a merger between M64 and a satellite galaxy over a billion years ago.

The red in this image is dust, as the galaxy gets its nickname from the dark streak that wraps around its nucleus on its left side. In optical that streak is dark. Here Webb’s infrared view sees it in false color red.

READERS: It appears that it is a very slow news day today. Other than SpaceX’s IPO, which is on-going and too soon to post any reports, I can so far find nothing much of great significance on which to report.

Two launches today by Japan and SpaceX

8:47 am

The beat goes on! Even as SpaceX proceeds today with the largest initial public offering of stock ever, raising an expected $75 billion in cash for its long term plans, the global launch industry marched on with two launches today.

First, Japan’s space agency JAXA successfully launched its H3 rocket on a test flight following a launch failure in December 2025. The rocket lifted off from JAXA’s Tanegashima spaceport in southern Japan, using its simplest configuration, with no solid-fueled strap-on boosters. Though the rocket deployed some cubesats, its main payload was a dummy satellite to test the rocket’s deployment system, which caused the 2025 failure by not holding its satellite in place. On today’s launch, the deployment system worked as planned, which means JAXA can now resume operational launches with H3.

This was Japan’s first launch in 2026.

Next, SpaceX placed another 29 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral Space Force Station in Florida. The first stage completed its 27th flight, landing on a drone ship in the Atlantic (58 days after its previous flight).

The leaders in the 2026 launch race:

70 SpaceX
36 China
8 Russia
8 Rocket Lab (plus two suborbital HASTE launches)

For the third straight year SpaceX leads the entire world combined in total launches, 70 to 63.

Parker makes 28th close fly-by of the Sun

12:48 pm

The overall flight plan for Parker
The overall flight plan for Parker. The green indicates
this most recent close approaches.

The Parker Solar Probe this past week successfully completed its 28th close fly-by of the Sun, zipping past its surface at a distance of only 3.8 million miles.

During this solar encounter, which started June 3 and ends Saturday, June 13, Parker’s four scientific instrument packages gathered data from inside the Sun’s atmosphere, or corona. Parker will begin returning detailed spacecraft telemetry on June 14, with science data transmission set to run from Wednesday, June 17 to Tuesday, June 30.

…Parker also equaled its record-setting speed of 430,000 mph — a mark that, like Parker’s distance to the Sun, was set during a close approach on Dec. 24, 2024, and matched during five flybys since, most recently on March 11. Parker will continue matching these speed and distance records during future flybys.

Engineers estimate the spacecraft’s heat shield experiences temperatures exceeding 1,700 degrees Fahrenheit with each close pass.

With each pass the spacecraft dives deep into the Sun’s corona and gathers data about it unobtainable from a distance. It is also gathering that data over time, as it first arrived in 2018, when the Sun was at its solar minimum with little sunspot activity. Since then it has ramped up to maximum and is presently thought to be on its way back down to minimum (though this still remains uncertain). Parker’s ability to gather data cross this timeline is invaluable for gaining a better understanding of the Sun’s behavior.

Two orbital launches today by China and SpaceX, plus a suborbital hypersonic launch by Rocket Lab

10:45 am

The beat goes on! Since last night both China and SpaceX successfully completed orbital launches.

First, China used its most powerful operating rocket, the Long March 5, to place what its state-run press called “a new communication technology test satellite” into orbit, the rocket lifting off from its coastal Wenchang spaceport. As the Long March 5 can haul very large payloads into orbit, it suggests this one satellite is unusually heavy.

Next, SpaceX successfully placed another 24 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California.

The first stage (B1071) successfully completed its 34th flight (38 days after its previous flight), landing on a drone ship in the Pacific. With this flight the stage moved past the space shuttle Atlantis, putting it in third place in the rankings for the most reused launch vehicle:

39 Discovery space shuttle
35 Falcon 9 booster B1067
34 Falcon 9 booster B1071
33 Atlantis space shuttle
32 Falcon 9 booster B1063
31 Falcon 9 booster B1069
28 Columbia space shuttle
28 Falcon 9 booster B1077
28 Falcon 9 booster B1078

Sources here and here.

Though it was not an orbital launch and thus isn’t added to my launch totals, Rocket Lab also launched last night, using its HASTE suborbital version of its Electron rocket to do a suborbital hypersonic test for the War Department, as part of its $190 million contract to do twenty such test flights. This appears to be the first of those launches.

UPDATE: The HASTE launch appears to have actually been an orbital one, with a second stage and kick stage, both of which reached orbit. No information has been released on the status of the classified payload, which I suspect was a test hypersonic missile that was accelerated to orbital speeds by that second stage and kick stage, but then flew a guided high speed planned suborbital test flight. Since this launch did place objects in orbit, and appears to have been 100% successful as planned I am including it in my launch totals below.

The leaders in the 2026 launch race:

69 SpaceX
36 China
8 Russia
8 Rocket Lab (plus two suborbital HASTE launches)

For the third straight year SpaceX leads the entire world combined in total launches, 69 to 62.

Another unsuccessful suborbital launch from proposed Nova Scotia spaceport

9:44 am

Proposed Canadian spaceports
Proposed Canadian spaceports

For the second time in less than seven months the Canadian startup company T-Minus unsuccessfully attempted a suborbital test launch from the proposed Spaceport Nova Scotia, owned and operated by the company Maritime Launch Services and funded mostly by a major $200 million lease by the Canadian government.

The launch was conducted from Spaceport Nova Scotia under approved regulatory and safety frameworks. The demonstration strengthened coordination among launch site teams and partners while refining launch operational procedures and the safety and security systems that govern all activities at the spaceport.

While two suborbital flights had been planned for today’s demonstration, the decision was made to conclude operations following the first flight in order to review mission data and incorporate lessons learned into future testing activities. The demonstration featured the launch of the Barracuda, a hypersonic, single-stage, solid-fuel suborbital vehicle capable of carrying payloads of up to 40 kilograms to altitudes of approximately 80 kilometres.

Full analysis of the flight data will continue over the coming weeks. However, initial data indicate that the vehicle operated nominally during the powered phase of flight before experiencing an anomaly late in the boost phase.

In other words, the first launch did not operate as expected, which forced the cancellation of the second launch. T-Minus had a similar result in its November 2025 test, making its record 2-for-2 in failures.

This launch was really designed as a PR event, not a space launch. Maritime invited numerous government officials and celebrities to watch, even as the leftist Carney government has tried to falsely sell its spaceport lease as a way to establish a sovereign launch capability for Canada.

Maritime itself has been trying to get this spaceport off the ground since 2016, with no success. Only in the last year it has come back to life due to that $200 million government lease. With that financing, Maritime has been able to sign up two different rocket startups to consider launching from Spaceport Nova Scotia, the German company Isar Aerospace and the South Korean company Innospace.

However, no orbital launches are presently scheduled, and it is likely none will occur before 2028. And when or if it happens, it will not be by a Canadian rocket company.

Stoke Space successfully completes all tank tests for 1st stage of its Nova rocket

9:24 am

Stoke's Nova rocket
Stoke’s Nova rocket, designed to be
completely reusable.

The rocket startup Stoke Space announced earlier this week it has successfully completed all tank tests for 1st stage of its Nova rocket, thus increasing the odds that the rocket’s first launch will occur before the end of this year.

During this campaign, the team filled both tanks above their maximum expected pressure conditions, demonstrated automated pressure control across a range of fill levels, and operated the vehicle through challenging environmental conditions, including hurricane-force winds and a severe lightning storm. More than just a successful structural test campaign, the result was a broader demonstration that Nova’s hardware, software, ground systems, and operations approach are maturing together.

The company noted that it is not unusual for new rockets to experience explosions and other failures during this testing phase, thus making its complete success without a failure “a significant achievement.”

Stoke has consistently refused to set a launch date as it has been developing its rocket. It approach has been simply “We will launch when we are ready.” It has had this luxury in that it has successfully raised $1.34 billion in private investment capital, attracted to the company because of its rocket’s radical design that will allow both its first and second stages to be reusable. The first stage will land vertically, as does SpaceX’s Falcon 9.

The second stage uses a revolutionary nozzle design that makes its return possible. Instead of a single central nozzle, the engine has a ring of small nozzles on the outside edge of its heat shield. The stage will then return to Earth like a capsule, with those nozzles adding force to control and slow its descent.

The rocket itself has a smaller payload capacity than a Falcon 9, but its ability to be completely reusable means its second stage is far more capable. It can fly multiple times, thus lowering the launch costs for its customers. It can also provide an orbital manufacturing site, like a Varda capsule, which will attract a much larger customer base.

A look back at a significant moment in human history: the first picture of the Moon’s far side

12:14 pm

The first picture ever taken of the Moon's far side, by Luna-3
Click for original image.

Today’s cool image is being posted not because of its beauty or high resolution, but because it was a significant first that shined a light on a mystery that had baffled all humanity since the first time a human being in Africa looked up and observed the Moon.

The picture to the right, reduced slightly and smoothed to remove some camera artifacts, was the first picture ever taken of the hidden far side of the Moon, captured by the Soviet Union’s Luna-3 probe on October 7, 1959, one day after it had passed less than 3,900 miles above the surface. As it moved away, it looked back, and took this picture from a distance of about 40,000 miles.

The picture ain’t what we are used to nowadays from space, but you need to put yourself back in time to truly appreciate it. For literally the entire history of humanity, this view had been hidden. Dreamers, philosophers, scientists, and ordinary people would look at the near side of the Moon almost nightly, but no one knew what was on the other side. Whole religious myths grew up about this unknown. Some science fiction writers of the 19th century fantasized there was air and water there and thus housed an alien civilization, purposely positioned so we couldn’t see it.

Suddenly, with this picture, that side was no longer hidden. This one Luna-3 picture showed humanity that the Moon’s far side was not much different than the near side, though much more cratered with fewer dark mare regions. It had no air or water. Nor were there alien civilizations.

But that age-old mystery was now solved. For those living in the 1950s, it was something of a revelation to see this picture. For those who came after, it is important to try to imagine the significance of that revelation. Suddenly, the mysteries of the universe were no longer unsolvable. Suddenly, we had the ability to solve them.

This picture, like all new knowledge, also brought with it new mysteries, based not on a hidden view but on real data and real questions. Now the goal was understand that data in order to solve the history of the Moon’s geology and how it fit into the formation of the Earth and the entire solar system. That endeavor is still on-going, with its solution not yet entirely in sight.

One last point: Though this picture is woefully inadequate compared to modern planetary images, it also carries a remarkable amount of good information that has since been confirmed by other spacecraft. To get an idea, compare it with a similar global view produced using Lunar Reconnaissance Orbiter (LRO)’s full dataset. The features match quite well, and a close look at the Luna 3 picture reveals many details not immediately evident that match well with the LRO image. The Russian engineers who made this happen should be rememberd and honored for their achievement.

New Webb data suggests little red dots are supermassive black holes embedded in gas cloud

11:02 am

Little Red Dot GLIMPSE-17775
Little Red Dot GLIMPSE-17775

Using spectroscopic infrared data obtained by the Webb Space Telescope, astronomers now posit that the mysterious little red dots found by Webb in the very early universe are supermassive black holes embedded in a dense cloud of ionized gas.

The scientists focused Webb on the little red dot dubbed GLIMPSE-17775, shown to the right in a false color image produced by Webb’s near infrared camera. You can read their paper here [pdf].

The spectroscopic data collected by Webb contains multiple lines of evidence that support the interpretation that little red dot GLIMPSE-17775 is a black hole star: a rapidly accreting, or growing, black hole enveloped in a dense gas cocoon, which is reprocessing the light emitted from near the black hole and producing the features seen in the spectrum.

Among the 40-plus lines that the team detected in GLIMPSE-17775’s spectrum were various independent indicators that all align with the BH* scenario [the name the scientists use for this model]. For example, the team found that many of the spectral lines, such as hydrogen, oxygen, and helium, do not fit a simple model of a rotating gas cloud. Instead, the best fit model includes a broadening effect known as electron scattering, a telltale sign that a dense, layered gas cocoon is enshrouding this source.

The strength and ratios of certain lines to each other, most notably the 16 iron lines that compose what the team has dubbed an “iron forest” and certain oxygen lines, require a high-energy source to produce them, like a rapidly accreting black hole. Additionally, astronomers noted the fluorescence and absorption of helium in the spectrum, both of which individually suggest that there is a dense medium enveloping a powerful source.

The researchers claim this theory will work to explain all the other little red dots that Webb has detected in the early universe. They also claim it explains how the dots could be there so soon after the Big Bang, as they don’t have to be as supermassive as first believed. If very large, there wasn’t time for them to coalesce following the Big Bang. This model suggests instead that they can be much smaller black holes, thus allowing time for their formation without contradicting present Big Bang cosmology.

There is of course a lot of uncertainty here. For example, GLIMPSE-17775’s data is microlensed, which distorts it. While scientists think they understand the distortions fully, their inability to see this object and the foreground object doing the microlensing from multiple perspectives requires them to make many assumptions that cannot be proven, and could very well be wrong.

Mitsubishi gets subsidy from Japan to develop its own orbital tug

9:52 am

The Japanese aerospace company Mitsubishi today announced that Japan’s Space Strategic Fund has awarded it a subsidy of an undisclosed amount to its develop its own orbital tug.

The goal is to develop an OTV [orbital transfer vehicle] that can respond flexibly to user needs, navigate between orbits, and load and release payloads in space without being limited to specific applications or transport routes. The company also aims to verify the feasibility of autonomous rendezvous, proximity operations and docking (RPOD) using physical AI and robotics for the safe and effective capture, handling and release of payloads in space.

The Space Strategic Fund was created by the Japanese government in 2023 as a ten year $6.6 billion program to encourage the growth of a private Japanese space sector, to essentially transition Japan from a government space program run and owned by its space agency JAXA to a independent and competing private sector, following the capitalism model.

That fund however was given to JAXA to manage, and so far it appears it has not moved aggressively to promote an independent sector. Inside, the awards it has given out so far have mostly been to either fund its own programs, or help its big space partners, such as Mitsubishi. This could change of course as privately-owned spacecraft begin garnering customers outside of JAXA. It is however taking a long time, and meanwhile Japan’s space industry continues to trail badly both China and India, and even South Korea. While these Asian companies are developing multiple rockets and spacecraft, Japan presently has no operational rockets, and its commercial space sector is barely alive.

India takes first step to privatize its largest rocket, the LVM3 or Bahubali

9:21 am

LVM3 launching a set of OneWeb satellites in 2022
LVM3 about to launch a set of OneWeb satellites in 2022

IN-SPACe, the agency assigned the job for shifting India’s space effort away from its space agency ISRO and to the private sector, yesterday released an Expression of Interest (EOI), asking India’s private aerospace industry for bids to take over operations of ISRO’s LVM3 rocket (also called Bahubali), its most powerful rocket that ISRO plans to use for its future manned and interplanetary missions.

The invitation for EOI, released on Tuesday, invites eligible Indian private companies or industry consortia to acquire and operationalise LVM3 technology from ISRO. The LVM3, often referred to as ISRO’s ‘Baahubali’ rocket, is the agency’s heaviest operational launch vehicle and is behind key missions including Chandrayaan 2 and 3. The selected private entity will receive technology transfer and extensive support from ISRO to absorb the technology and begin manufacturing and launching LVM3 vehicles commercially.

The EOI invitation also lays down the eligibility criteria for the applicable private entities. ISRO’s handholding and infrastructure support is proposed for a defined period of 42 months or until the realisation and launch of two LVM3 vehicles by the selected entity, whichever comes earlier.

The eventual goal is for the private sector to market LVM3 for commercial purposes, outside of ISRO’s Gaganyaan and space station manned program. While ISRO will continue to operate the rocket to launch manned missions as well as the country’s proposed Bharatiya Antariksh Space Station (BAS), the private company that takes over LVM3 will sell it to the international market for profit. As this is a powerful rocket, it can compete directly with SpaceX’s Falcon 9, ULA’s Vulcan, Blue Origin’s New Glenn, and Arianespace’s Ariane-6.

IN-SPACe has already begun this process with ISRO’s smallsat SSLV rocket, transferring operations in June 2025 to Hindustan Aeronautics Limited (HAL). There are also indications it is trying to do the same with ISRO’s mid-sized PSLV rocket. If all three transfers go through, almost all of ISRO’s rockets will be operated by the private sector.

Don’t expect this transition to the private sector to happen quickly. As we have seen in the U.S., the shift away from a government-run space program to a chaotic free capitalist space industry can take many years, decades even. And its eventual success is never guaranteed, as government agencies fight hard to protect their turf, and they have the power of government coercion to back them up.

China picks four of its pseudo-companies to launch its new Qingzhou cargo freighter

China’s Qingzhou unmanned cargo freighter

China’s government has now chosen four of its pseudo-companies to allow them to bid on launching its new smaller and less costly Qingzhou freighter to bring cargo its Tiangong-3 space station.

Launch firms Galactic Energy, CAS Space, OrienSpace and Landspace were shortlisted to launch the Qingzhou cargo spacecraft, following the launch of a prototype of the supply vessel March 30. The four were named in a public notice posted to China’s national tendering platform June 5, with the notice period closing June 9. The notice does not indicate the selection of a final provider.

The full scale Qingzhou cargo spacecraft is tentatively scheduled for launch in January 2027, subject to the final launch window, according to the tender information. The mission is intended to dock at Tiangong to provide supplies for the first time. Qingzhou is developed by the Innovation Academy for Microsatellites of the Chinese Academy of Sciences (IAMCAS), and is one of two low-cost space station resupply spacecraft being developed under a program initiated by China’s human spaceflight agency, CMSEO, to support Tiangong. The prototype completed rendezvous tests in April.

Of these four pseudo-companies, CAS Space and Landspace are most likely to get the first Qingzhou launch contracts. CAS Space is wholly-owned by a government agency, giving it a distinct political advantage. Its Kinetica-2 solid-fueled rocket has also flown a number of times successfully, including one mission that launched the first Qingzhou prototype in March 2026.

Landspace’s rocket, the Zhuque-2, has also flown successfully a number of times (with one failure). As an independent pseudo-company with no direct ownership by the government, its political connections are not as good. At the same time, all these pseudo-companies are essentially owned by the communist government, which recognizes private property only at its convenience.

Science operations about to resume on Europe’s two-satellite Proba-3 space telescope

After months of trouble-shooting after losing contact with the coronagraph probe of Europe’s two-satellite Proba-3 solar space telesscope in February 2026, engineers have successfully resumed precise formation flying of the two spacecraft, and are about to resume full science observations of the Sun’s corona.

The mission is explained in the graph to the right. In February all contact with the coronagraph, which holds the mission’s science instruments, was lost. After a month of struggle, engineers regained contact, but it required another few months of trouble-shooting to pin down the cause of the problem and fix it. The press release provides almost no information about that cause, other than this one quote that hints it was software-based.

“One by one, we have checked the status of each of the spacecraft’s subsystems. We have also been able to successfully perform the operations that proved critical in February,” says Damien. “Back then, it triggered the unfortunate chain reaction that led to loss of connection with the spacecraft, but after patching the root cause in the software, we were confident that this activity will cause no further issues.”

With both spacecraft once again operating in tandem, the occulter can block the Sun’s light so the coronagraph can observe the Sun’s corona, its atmosphere. Essentially, Proba-3 creates an on-going artificial eclipse so as to make the corona visible for study.

The rings of Saturn

Saturn's rings in 2006
Click for original image.

Cool image time! Rather than post another Mars image, I decided today to dig back into the Cassini orbiter archives, which orbited Saturn for almost fourteen years, beginning in 2004.

The picture to the right, reduced and sharpened to post here, was taken on September 6, 2006 from about 397,000 miles away. It has a resolution of about 22 miles per pixel, so no object smaller than that is resolved.

This wide and sweeping view of the sunlit rings of Saturn takes in the impressive variety in their structure — from the clumpy and perennially intriguing F ring to the many waves, ringlets and gaps in the A and B rings and the Cassini Division in between.

The F ring is the outermost thin clumpy ring. The B ring is the brighter set of rings inside the wide Cassini Division, with the A ring the darker set beyond. For a labeled map of all the rings and gaps go here. The seemingly incoherent naming sequence is because the rings are named alphabetically in their order of discovery. Thus, the A ring was first identified, followed by the inner B Ring. The F ring was discovered by the Pioneer 11 when it flew past Saturn in 1979.

While the many Cassini wide-view images of Saturn’s rings tend to look somewhat the same, they all remain breath-taking regardless. Imagine a hotel in orbit around Saturn, where you could look out your window and see this evolve over time as your spacecraft orbited the ringed planet.

NASA announces crew and flight plan for Artemis-3 Earth orbit mission next year

12:22 pm

NASA today unveiled both the four-person crew that will fly its Artemis-3 Earth orbit mission next year as well as the mission’s basic plan, assuming both SpaceX and Blue Origin can get their respective lunar landers ready in time.

Crew assignments are as follows:

  • NASA astronaut Randy Bresnik, commander
  • ESA (European Space Agency) astronaut Luca Parmitano, pilot
  • NASA astronaut Frank Rubio, mission specialist
  • NASA astronaut Andre Douglas, mission specialist

… NASA astronaut Bob Hines was named as a backup crew member.

Except for Douglas, all are veterans.

The mission details were also announced:

Artemis III includes launching the world’s most powerful rockets in short order. Blue Origin’s lander pathfinder, which is able to stay in orbit for multiple weeks, will launch first and await the crew. NASA will send the astronauts aboard Orion by SLS to orbit Earth, before rendezvousing in space with the company’s lander test article and spending about two days docked together for tests and technology demonstrations, including entering the lander.

After completing docked operations with Blue Origin, Orion will detach and await Starship. SpaceX’s Starship pathfinder will launch and meet up with Orion to spend about a day connected for checkouts and testing. After that, Orion and its crew will undock and return home, splashing safely down in the Pacific Ocean where a team from the U.S. Navy and NASA will recover the astronauts.

In total, the crew is expected to remain in space for about two weeks, with exact mission length to be determined in real-time based on launch, rendezvous, and docked operations.

All of this assumes that New Glenn has been fixed and is operational by late 2027 and can launch the Blue Moon Mark-2 manned lunar lander. It also assumes the lunar lander version of Starship is ready and operational and man-rated. It also assumes NASA can get SLS stacked and ready for launch much faster than previously expected.

All are big assumptions.

Other issues: Orion will be testing its docking system and its newly redesigned heat shield for the first time, with humans on board. As the return will be from low Earth orbit, the stress on the heat shield will be relatively light, reducing the risk considerably. Similarly, if the docking system fails they simply won’t dock, and can return to Earth instead. Both should work, however, as neither is cutting edge technology.
