SpaceX launches 29 more Starlink satellites

11:01 pm

The beat goes on: Even as everyone (including myself) was focused on NASA’s Artemis-2 lunar mission, SpaceX remained centered on its own space effort. This evening it placed another 29 Starlink satellites into orbit, its Falcon 9 lifting off from Cape Canaveral Space Force Station in Florida.

The first stage completed its 15th flight, landing on a drone ship in the Atlantic only 23 days after its previous flight.

Below is the leader board for the 2026 launch race, which I had forgotten to include in the previous two launches by SpaceX and NASA. Those posts have now been updated to include it.

41 SpaceX
16 China
5 Rocket Lab
3 Russia

SpaceX continues to lead the entire world combined in total launches, as it did in both ’24 and ’25.

Chinese pseudo-company Space Pioneer was also scheduled today to do the first demo launch of its Tianlong-3 orbital rocket, which appears in many ways to be a Falcon 9 copy. At this moment there are no reports out of China of what happened, though Jonathan McDowell reports on X of speculation that it was a failure. We will know more in a day or so.

Space Pioneer is the pseudo-company that in 2024 had this rocket’s first stage do an unplanned launch during a static fire engine test. That incident delayed this launch attempt by at least one year.

Orion fires engines and is now on its way around the Moon

4:55 pm

After reviewing the operation of Orion capsule during its first day in orbit, the NASA Artemis-2 management team approved sending the spacecraft to the Moon.

The burn occurred at 7:49 Eastern. The live stream of that burn is embedded below.

At this moment NASA and the crew are committed. No matter what happens, they cannot return to Earth any earlier than about nine days from now. And when they return, they will have to do a direct dive into the atmosphere, heading to splashdown. The Orion heat shield at that point must work.

Neptune’s rings, as seen by Voyager-2 in 1989

2:05 pm

The rings of Neptune as seen by Voyager-2
Click for original image.

Cool image time! The picture to the right, cropped, reduced slightly, and sharpened to post here, was taken by Voyager-2 on August 26, 1989 shortly after it had completed its close fly-by of Neptune, looking back at the planet from a distance of about 175,000 miles.

The two main rings are clearly visible and appear complete over the region imaged. … Also visible in this image is the inner faint ring at about 25,000 miles from the center of Neptune, and the faint band which extends smoothly from the 33,000 miles ring to roughly halfway between the two bright rings. Both of these newly discovered rings are broad and much fainter than the two narrow rings.

These long exposure images were taken while the rings were back-lighted by the sun at a phase angle of 135 degrees. This viewing geometry enhances the visibility of dust and allows fainter, dusty parts of the ring to be seen. The bright glare in the center is due to over-exposure of the crescent of Neptune. The two gaps in the upper part of the outer ring in the image on the left are due to blemish removal in the computer processing. Numerous bright stars are evident in the background. Both bright rings have material throughout their entire orbit, and are therefore continuous.

While Voyager-2 took other pictures of these rings (here, here, here, here, and here), I think this picture shows the rings best, if not terrible well. Images using the Hubble and Webb space telescopes as well as others have not been better.

The rings were first confirmed to exist in the mid-1980s, shortly before Voyager-2’s fly-by. We now think there are five rings total, all made of dark material, likely a mix of carbon-based molecules, much of it the equivalent of dust and soot.

The new Rubin telescope discovers over 11,000 new asteroids in first observations

11:07 am

Rubin's first asteroid discoveries
Click for full animation.

The new Rubin Observatory, a ground-based telescope in Chile, has discovered over 11,000 new asteroids in its first preliminary observations, with most in the main asteroid belt but a large number in the Kuiper Belt beyond Neptune and 33 previously unknown near-Earth asteroids.

The graphic to the right, annotated by me to post here, shows all of Rubin’s asteroid detections in light blue.

The submission to MPC [Minor Planet Center] comprises approximately one million observations, taken over the span of a month and a half, of over 11,000 new asteroids and more than 80,000 already known asteroids, including some that had previously been observed but were later “lost” because their orbits were too uncertain to predict their future locations. You can interact with all of Rubin’s asteroid discoveries in the Rubin Orbitviewer, which uses real data to provide an intuitive way to explore the structure of our cosmic backyard in three dimensions and in real time. Also, visit the Rubin Asteroid Discoveries Dashboard to learn about the new objects Rubin has uncovered.

…Among the newly identified objects are 33 previously unknown near-Earth objects (NEOs), which are small asteroids and comets whose closest approach to the Sun is less than 1.3 times the distance between Earth and the Sun. None of the newly discovered NEOs pose a threat to Earth, and the largest is about 500 meters wide.

Astronomers predict that Rubin will eventually find 90,000 new near-Earth objects, with some expected to pose a risk of hitting the Earth. It does this by repeatedly surveying the southern sky with its large mirror, then identifying new objects with its sophisticated software.

Scientists: Saturn’s magnetic field is warped

9:41 am

Saturn's theorized magnetic field

Using six years of archival data from the Cassini Saturn orbiter, scientists now think Saturn’s magnetic field is lopsided, pulled sideways due to the planet’s very fast rotation as well as the material that surrounds the ringed planet.

The graphic to the right, Figure 4 from the research paper [pdf], compares the Earth’s symmetric magnetic field (top) with that of Saturn’s (bottom). From the press release:

The team found that the cusp was dragged to the right as viewed from the Sun, and was located most often between 1:00 and 3:00 (as it might appear on a clockface), compared to 12:00 as it would be on Earth.

The researchers said this was likely because of Saturn’s extremely fast rotation (a Saturn day is 10.7 hours) and the heavy “soup” of plasma (ionised gas) it pulls around it, a product of gases emitted by Saturn’s moons, especially Enceladus. Together, these are thought to drag the magnetic field lines to the right. But more simulations are needed to confirm this interpretation.

When the solar wind hits the Earth’s magnetic field lines at the cusp, that wind is funneled down along those lines to the poles, where it produces the aurora. This new analysis at Saturn will help scientists better understand the behavior of Saturn’s aurora, which is made even more complex by the planet’s many moons.

SpaceX files initial paperwork for going public

8:54 am

SpaceX logo

SpaceX yesterday filed the first confidential paperwork the the Securities and Exchange Commission (SEC) for its initial public offering (IPO) of public stock, now targeting a June-July time frame.

The filing was reported by Bloomberg, the Wall Street Journal and Reuters, citing unnamed sources familiar with the matter. SpaceX did not immediately respond to a request for comment. The SEC said it had no comment on the matter. The filing will lead to a sale of shares by June or July, according to the published reports. Confidential filings are used by companies to share information with the SEC and investors before they have to disclose to the broader public.

How much SpaceX plans to raise through a sale of some of its shares are not yet available due to the confidential nature. But CEO and principal shareholder Elon Musk is expected to control a majority of voting shares once the details are revealed. And it could make Musk, already the world’s richest person, that much richer.

SpaceX was valued at $800 billion and xAI $230 billion at their most recent funding round in January according to PitchBook, a research firm that tracks the valuation of private companies. That puts the combined companies’ worth at more than $1 trillion.

SpaceX also now includes X (formerly Twitter) that Musk bought for $44 billion, so the combined company is actually even larger. We still do not know any details, such as the number of shares to be sold as well as the initial sale price. One rumor has indicated that SpaceX wants to reserve 30% for sale to individuals, a number much higher than usual. Other rumors say that Musk is designing the sale to make sure he remains the majority stock-holder and thus in control of all three companies.

Stock experts have predicted this stock sale could garner SpaceX as much as $75 billion in cash, which would give it the resources to not only build its proposed million-satellite data center constellation in orbit but also develop the Starship/Superheavy infrastructure to build its own data center on the Moon. And along the way SpaceX would have the funds to do its own space program to settle Mars.

If SpaceX does raise that much, it will truly become America’s space program, doing far more that NASA and much faster — financed voluntarily by the American people.

SLS successfully puts Orion into orbit

3:46 pm

SLS less than a minute after launch
SLS less than a minute after launch

NASA’s SLS rocket today successfully launched the Orion capsule, carrying three Americans and Canadian on a planned ten-day mission swinging around the Moon and back to Earth.

During the countdown there were two minor issues, the second of which causes a slight ten-minute delay in the launch. Both were resolved very quickly, though one wonders if NASA can ever do a launch with this rocket without such issues during countdown.

The crew will remain in Earth orbit until tomorrow, checking out the capsule and its systems. Once they have confirmed these are working as expected, they will then fire their engines to head to the Moon.

The live stream can be viewed here.

As this was the first U.S. government launch this year (and the first since 2022), the leader board for the 2026 launch race remains unchanged:

40 SpaceX
16 China
5 Rocket Lab
3 Russia

SpaceX continues to lead the entire world combined in total launches, as it did in both ’24 and ’25.

Court dismisses lawsuit from victims of multiple Boeing 737-Max crashes

11:44 am

Boeing Logo
Corrupt from top to bottom

The Fifth Circuit Court today dismissed the lawsuit by the families of the 346 victims of two Boeing 737-Max crashes, caused by Boeing’s admitted malfeasance and corruption, preventing those families from blocking a sweetheart deal between Boeing and the Justice Department that largely lets Boeing off the hook.

The court’s decision was vile in its own way, as noted by one of their lawyers:

In today’s ruling, the Circuit said that the families’ victims rights challenges to these agreements came too late to allow any remedy. But earlier, in 2023, the Circuit had said that the families’ challenges were “premature.” The fact that the families now will seemingly never receive any remedy is a cruel judicial bait-and-switch, revealing how much work remains to be done to create truly enforcable crime victims’ rights in the criminal justice system. [emphasis mine]

In other words, this court’s rulings over time essentially made it impossible for these victims to ever claim their rights under the Crime Victims’ Rights Act (CVRA).

The background: In 2018 and 2019 two of Boeing’s new 737-Max planes crashed, due to Boeing’s own design. The investigation into the crashes revealed that Boeing knew about these design flaws, lied about it to federal authorities, while doing nothing to fix the identified problems (behavior to which it has admitted). In 2021 Boeing pleaded guilty to malfeasance and corruption charges, and was given three years to clean up its act or face criminal prosecution.

When after three years Justice found Boeing had instead lied again while doing little to fix things, Justice first proceeded with prosecution, only to suddenly back off and make a plea deal that would have Boeing pay and/or invest up to $1.1 billion, about half of which would go to victims’ families.

To understand the opposition by the families to this deal, you need to read what the Justice Department determined about Boeing’s behavior.

A Justice Department investigation uncovered the fact that Boeing had lied to the FAA about the safety of the aircraft—lies that led directly and proximately to the crashes killing 346 passengers and crew. On January 7, 2021, the Justice Department filed a criminal information with a one-count conspiracy charge against Boeing, alleging that “From at least in or around November 2016 through at least in or around December 2018, in the Northern District of Texas and elsewhere, the Defendant, The Boeing Company, knowingly and willfully, and with the intent to defraud, conspired and agreed together with others to defraud the United States by impairing, obstructing, defeating, and interfering with, by dishonest means, the lawful function of a United States government agency.”

The families didn’t simply want money, they wanted justice. They wanted Boeing and its management to be prosecuted for their part in allowing 346 people to die unnecessarily.

At this moment, it appears they won’t get it, because of a similar malfeasance at the Fifth Circuit, which now seems as corrupt and as dishonest as Boeing.

Voyager-2 discovered Neptune to be a planet of quickly changing weather

10:53 am

Neptune's fast changing weather
Click for source.

Cool image time! When Voyager-2 flew past Uranus in 1986, the data showed the gas giant’s weather to be relatively sedate and quiet, with little changing during the fly-by. Scientists expected this: Uranus’s distance from the Sun meant it got little energy to fuel an active climate, with any activity produced by internal heating due to the gravitational pressure of its mass. And Uranus did not produce that much heat internally.

When Voyager-2 passed Neptune three year later, the scientists expected something similar, or even less, due to Neptune’s greater distance from the Sun. Instead, Voyager-2’s data showed Neptune’s weather patterns to be changing constantly and quickly, as illustrated by the three images of the Great Dark Spot to the right, the biggest storm on Neptune at that time and located in the planet’s southern mid-latitudes.

The bright cirrus-like clouds of Neptune change rapidly, often forming and dissipating over periods of several to tens of hours. In this sequence spanning two rotations of Neptune (about 36 hours) Voyager 2 observed cloud evolution in the region around the Great Dark Spot at an effective resolution of about 60 miles per pixel. The surprisingly rapid changes which occur over the 18 hours separating each panel shows that in this region Neptune’s weather is perhaps as dynamic and variable as that of the Earth. However, the scale is immense by our standards — the Earth and the [Great Dark Spot] are of similar size.

In Neptune’s frigid atmosphere, where temperatures are as low as 55 degrees Kelvin (-360 F), the cirrus clouds are composed of frozen methane rather than Earth’s crystals of water ice.

Subsequent observations by the Hubble Space Telescope in 1994 found this Great Dark Spot was gone, replaced by a comparable storm in the northern hemisphere. Further Hubble observations found Neptune’s storms tend to last about two years, fading as they drifted towards the equator. Those observations however also detected storms drifting away from the equator. Other research suggested the storms might be influenced by the Sun’s sunspot cycle.

All of the data post-Voyager-2 remains very coarse and uncertain, as we are looking at Neptune at a great distance. Thus, no theory about what is happening carries much weight, especially because we do not know why Neptune produces so much more internal heat than Uranus, fueling this fast-changing weather. For example, Neptune gets 1/20th of the energy received by Jupiter, yet its atmosphere appears even more active and variable.

India’s space agency requests proposals for building landing legs for its next new rocket

8:59 am

NGLV as proposed in November 2025
NGLV (the two rockets in the middle) as proposed
in November 2025. Click for bigger image.

India’s space agency ISRO has issued a request for bids from the country’s commercial aerospace sector to build landing legs for its next new rocket, dubbed the Next Generation Launch Vehicle (NGLV).

The tender, titled “Fabrication of Landing Leg Hardware with materials for Advanced Development Module for In-situ Reusable Technologies (Admire) VTVL (10 units)”, seeks industry participation in developing critical components for a vertical take-off, vertical landing (VTVL) test vehicle under the ADMIRE programme.

…According to ISRO’s tender documents, the selected vendor will be responsible for end-to-end development, including procurement of raw materials, manufacturing, quality control planning, and final delivery of landing leg hardware. The project has been structured into three distinct phases spanning approximately 12 months.

The NGLV rocket was first approved by the India government in September 2024. Since then ISRO has completed the preliminary design of its methane engine, but has also revised the rocket’s design twice, in October 2024 and again in November 2025. This new landing leg contract suggests the agency hopes to do some test hops of a first stage prototype a year from now.

A 2nd Starlink satellite since December fails catastrophically

8:38 am

According to reports from two different companies (here and here) that monitor objects in orbit, a Starlink satellite broke apart for unknown reasons on March 29, 2026.

SpaceX yesterday confirmed the incident.

On Sunday, March 29, Starlink satellite 34343 experienced an anomaly on-orbit, resulting in loss of communications with the satellite at ~560 km above Earth. Latest analysis shows the event poses no new risk to the Space_Station, its crew, or to the upcoming launch of NASA’s Artemis II mission. We will continue to monitor the satellite along with any trackable debris and coordinate with NASA and the USSpaceForce.

This is the second time in just over three months that a Starlink satellite has failed suddenly. In mid-December a Starlink satellite began to tumble when fuel began venting from a tank. It burned up in the atmosphere a month later.

Considering that SpaceX has approximately ten thousand Starlinks in orbit, any failures should not be a surprise. You launch that many, some are going to fail. That the company has only had two such failures indicates instead SpaceX’s incredible quality control in manufacturing, as almost every satellite works as expected with no such failure.

Countdown begins for the Artemis-2 mission around the Moon

11:57 pm

NASA this afternoon began the two-day long countdown leading up to the planned 6:24 pm (Eastern) launch of its Artemis-2 mission, sending three Americans and one Canadian around the Moon.

The onsite countdown clock started ticking down at 4:44 p.m. EDT to a targeted launch time of 6:24 p.m. on Wednesday, April 1. Artemis II is the first crewed launch of NASA’s SLS (Space Launch System) rocket and Orion spacecraft.

…NASA and weather officers with the U.S. Space Force’s Space Launch Delta 45 continue to pay close attention to weather conditions ahead of tanking operations. The weather forecast for launch day shows an 80% chance of favorable weather conditions with primary concerns being cloud coverage and the potential for high winds in the area. Teams will continue to monitor the weather in the coming days.

The ten-day mission will use the SLS rocket, which has only flown once previously, and has had repeated fueling issues prior to that 2022 launch as well as during dress rehearsal countdowns last month. It will also use an Orion capsule with a questionable heat shield and an untested life support system.

SpaceX launches first stage for record 34th time, passing shuttle Atlantis

2:25 pm

SpaceX today successfully launched another 29 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral Space Force Station in Florida.

The first stage (B1067) completed its 34th flight, landing on a drone ship in the Atlantic, only 32 days after its previous launch. With this flight, this stage passed the space shuttle Atlantis to hold second place in the rankings of the most reused launch vehicle.

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

Sources here and here.

SpaceX continues to recycle its first stages in a month or less, so expect this booster to pass Discovery before the end of the year. We should also expect all the boosters in the list above to do the same by the end of next year, though it is possible some will be retired as SpaceX begins to transition from its Falcon 9 high launch rate to using Starship/Superheavy instead.

The leaders in the 2026 launch race:

Brownsville’s mayor: SpaceX has brought billions of dollars to the region

12:04 pm

According to Brownsville’s mayor, John Cowen, SpaceX has brought billions of dollars to the region as well as created tens of thousands of jobs, and should be unanimously hailed by everyone there.

“The aerospace giant has infused $13 billion into into the economy across Brownsville and South Texas. It has created 24,000 direct and indirect jobs across the region, with approximately 4,000 jobs on site today. It is projected that 4,000 more jobs are coming,” Cowen said.

Cowen made his remarks about SpaceX at his 2026 State of the City Address, held March 25 at Texas Southmost College’s Performing Arts Center.

“SpaceX has generated more than $305 million in tax revenue. It has managed business relationships with more than 350 suppliers, putting $147 million into the regional supply chain,” Cowen said.

None of this is a surprise, except to some local and national news outlets that like to act as PR departments for the fringe activist groups — Save RGV, the South Texas Environmental Justice Network and the fake Indian tribe dubbed the Carrizo/Comecrudo Nation of Texas — that have opposed SpaceX’s Boca Chica operations from day one, and have repeatedly gone to court to try to shut it down. Those news outlets always give these activists a big bullhorn to tout their position, even though they represent practically no one in the region and likely get their funding from leftist sources outside of Texas.

Voyager-2’s view of clouds on top of clouds on Neptune

11:45 am

Neptune's upper clouds
Click for original image.

Time to continue our cool image tour this week of the Voyager-2 archive of Neptune, taken during the spacecraft’s August 25, 1989 close fly-by of the gas giant, zipping only 2,700 miles above the cloud-tops. This remains the only mission to visit Neptune so far.

The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken two hours before Voyager-2’s closest approach. From the caption:

These clouds were observed at a latitude of 29 degrees north near Neptune’s east terminator. The linear cloud forms are stretched approximately along lines of constant latitude and the sun is toward the lower [right]. The bright sides of the clouds which face the sun are brighter than the surrounding cloud deck because they are more directly exposed to the sun. Shadows can be seen on the side opposite the sun.

These shadows are less distinct at short wavelengths (violet filter) and more distinct at long wavelengths (orange filter). This can be understood if the underlying cloud deck on which the shadow is cast is at a relatively great depth, in which case scattering by molecules in the overlying atmosphere will diffuse light into the shadow. Because molecules scatter blue light much more efficiently than red light, the shadows will be darkest at the longest (reddest) wavelengths, and will appear blue under white light illumination.

The resolution of this image is 6.8 miles per pixel and the range is only 98,000 miles. The width of the cloud streaks range from 30 to 125 miles, and their shadow widths range from 18 to 30 miles. Cloud heights appear to be of the order of 31 miles.

Of all the high resolution images taken of Neptune by Voyager-2, this is the only one that clearly shows some dimensionality. Later photographs taken by Hubble and other ground- and space-based telescopes can only show global views that are far less sharp than the global views produced by Voyager-2.

This picture hints at Neptune’s very complex weather patterns, which has no well-defined surface and is made up mostly of gas and liquid. Though scientists have used Hubble to roughly track those weather patterns, they can only glean the most basic facts. For example, its fast-changing weather appears to be driven by high winds, thought to move as fast as 1,300 miles per hour. This fact however is woefully incomplete and very uncertain, as we have no way to track detailed weather patterns at multiple depths.

Our tour will continue tomorrow.

A soft barred galaxy with an active nucleus

A barred galaxy with an active galactic nucleus
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 two different surveys aimed at studying galaxies with what scientists call active galactic nuclei.

IC 486 lies right on the edge of the constellation Gemini (the Twins), around 380 million light-years from Earth. Classified as a barred spiral galaxy, it features a bright central bar-shaped structure from which its spiral arms unfurl, wrapping around the core in a smooth, almost ring-like pattern.

…At the galaxy’s center a noticeable white glow outshines the starlight around it. This is light given off by IC 486’s active galactic nucleus (AGN), powered by a supermassive black hole more than 100 million times the mass of the Sun. Every sufficiently large galaxy hosts a supermassive black hole at its center, but some of these black holes are particularly ravenous, marshaling vast amounts of gas and dust into swirling accretion discs from which they feed. The intense heat generated by the orbiting disc of material generates intense radiation up to and including X-rays, which can outshine the entire rest of the galaxy. In these cases, the galaxy is known as an active galaxy, with an AGN at its center.

For comparison, the relatively inactive supermassive black hole at the center of the Milky Way has a mass of about four million Suns, considerably smaller than IC 486’s. Why one is active and the other not however is not yet truly understood, though their different masses might provide part of the explanation.

Two launches from China and SpaceX early today

9:42 am

Early this morning both SpaceX and China successfully launched rockets. First, SpaceX completed its sixteenth Transporter mission placing 119 payloads in orbit, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California.

The first stage completed its 12th flight, landing on a drone ship in the Pacific. A detailed description of the 119 payloads can be found here.

Next, China successfully completed the maiden launch of its Kinetica-2 rocket, lifting off from its Jiuquan spaceport in northwest China and placing three demonstration satellites into orbit. The rocket is built by the pseudo-company CAS Space, which is entirely owned by one of China’s government space agencies.

According to the developers, the rocket stands 53 meters tall, with a core stage diameter of 3.35 meters and a fairing 4.2 meters wide. At liftoff, it weighs 625 tons and produces 753 tons of thrust. It can deliver up to 12 tons to a 200 kilometers low Earth orbit or 8 tons to a 500 kilometers sun-synchronous orbit.

On this launch, the liquid-fueled core stage and two side boosters were expendable, and crashed somewhere in China. China will use this rocket to partly replace its older expendable Long March 2 and Long March 3 rockets that use very toxic hypergolic fuels, thus reducing the risk to its citizens somewhat from crashing lower stages. Eventually the plan is to make the core stage and boosters reusable, so that they no longer crash uncontrolled inside China.

The leaders in the 2026 launch race:

39 SpaceX
16 China
5 Rocket Lab
3 Russia

SpaceX continues to lead the entire world combined in total launches, as it did in both ’24 and ’25.

SpaceX has another Starlink launch scheduled for later today, using a first stage on a record 34th flight.

Another rocket startup in India hopes to launch from its own spaceport

India’s spaceports, active, under construction, or proposed

A new rocket startup in India, dubbed Bharath Space Vehicle (BSV), is not only building a commercial rocket to launch smallsats, it hopes to establish its own private spaceport near the town of Kodinar in western India.

BSV has proposed a launch complex near Kodinar in Gujarat’s Gir Somnath district. Gujarat’s Science and Technology Minister Arjun Modhwadia told the state assembly that IN-SPACe has identified a suitable location between Diu and Kodinar for a satellite launch facility, comparable to Sriharikota.

The coastal location offers open sea access and favourable launch corridors for specialised satellite trajectories. Isro had earlier evaluated a Gujarat site for its SSLV launch complex before Kulasekarapattinam in Tamil Nadu was selected.

Sriharikota has been operated for decades by India’s space agency ISRO. Kulasekarapattinam is a new ISRO spaceport set to begin operations next year, focused on launching its Small Satellite Launch Vehicle (SSLV) for commercial missions. Hope Island is a proposed private and commercial spaceport, under study.

BSV’s rocket is called Agasthya-1 and will use liquid-fueled engines. It appears to be similar in design to SpaceX’s first rocket, the Falcon-1.

Though the company’s founders are all ISRO veterans who helped develop its rockets, its website makes no mention of a launch schedule. At present, India has two rocket startups, Skyroot and Agnikul, that appear close to their first orbital launch.

China’s government strengthens its commitment to space

8:01 am

China's long term launch record
Taken from my 2025 year-end report on the state of
global launch industry.

In the Chinese government’s most recently announced five-year plan, it appears it has increased its commitment to its space program and its government-controlled commercial space sector.

Aviation and aerospace was elevated at the Two Sessions [conference earlier this month] to a ‘pillar industry’—a step up from its previous classification as an emerging sector. For the first time, the 15th 5-year plan (2026–30) explicitly sets the goal of building China into a space power by 2030.

The 5-year plan prioritizes reusable launch vehicles, large-scale satellite constellations, and the commercialization of space applications, with cost reduction cast as central to long-term viability. Satellite internet has been earmarked for rapid development as part of broader ambitions around integrated space-air-ground connectivity. A new ‘Space+’ framing suggests that satellite infrastructure is being treated as part of the broader industrial system, with growing interest in on-orbit computing rather than communications alone.

…But the sector still runs on patient state capital—a funding model that has enabled rapid scaling while deferring any serious test of commercial viability. No domestic launch provider has yet turned a profit, and closing the cost gap with SpaceX on reusable rockets remains the industry’s central challenge.

The report at the link is very detailed. Though it comes from a Chinese-based think tank that almost certainly gets funding and supervision from the Chinese communists, it is definitely worth reading. It notes the areas where China is doing well — its Beidou GPS-type constellation and its manned space program — as well as those areas it has come up short — re-usable rockets and its mega-satellite constellations.

Though the graph to the right illustrates the long-term growth of China as a space power, it has not yet been able to match the U.S. in these two areas, mostly because of SpaceX. Moreover, the inability of China’s pseudo-rocket companies to get its reusable rockets operational is hindering the ability of China’s pseudo-satellite companies to launch their satellites. In both cases this new five-year plan appears to be applying pressure on these pseudo-companies to get moving, or the government will take over.

I must repeat again that the Chinese government’s support for space is deep and widespread, strengthened by that government’s almost two-decade-long policy of using that program as a training ground for its political leaders. Many of its successful space industry managers have been promoted to higher political office, and thus wield great power in deciding policy. Their pro-space roots clearly influence that policy in favor of China’s space effort.

Astronaut Mike Fincke finally reveals details of his medical emergency on ISS

9:33 am

Astronaut Mike Fincke, who had an undisclosed medical issue on ISS in January 2026 that forced the early return of his crew, has finally provided details of what happened.

Four-time space flier Mike Fincke said he was eating dinner on Jan. 7 after prepping for a spacewalk the next day when it happened. He couldn’t talk and remembers no pain, but his anxious crewmates jumped into action after seeing him in distress and requested help from flight surgeons on the ground. “It was completely out of the blue. It was just amazingly quick,” he said in an interview with The Associated Press from Houston’s Johnson Space Center.

Fincke, 59, a retired Air Force colonel, said the episode lasted roughly 20 minutes and he felt fine afterward. He said he still does. He never experienced anything like that before or since. Doctors have ruled out a heart attack and Fincke said he wasn’t choking, but everything else is still on the table and could be related to his 549 days of weightlessness. He was 5 ½ months into his latest space station stay when the problem struck like “a very, very fast lightning bolt.”

Fincke hopes he can fly in space again, but I doubt NASA would agree if the cause of this incident is not identified. His other option then would be to get hired by one of the commercial space station companies to fly to their stations, but even they might be reluctant to hire him.

Rocket Lab launches GPS-type demo satellite for Europe

9:05 am

Rocket Lab this morning successfully placed a European Space Agency (ESA) smallsat into orbit, its Electron rocket lifting off from one of its two launchpads in New Zealand.

The smallsat, dubbed Celeste, is the first of two such demo satellites that ESA has contracted Rocket Lab to launch. They are designed to test a low Earth orbit constellation for providing global navigation and location information to users on the ground, similar to the U.S.’s GPS constellation. Celeste will work from low orbit with Europe’s medium orbit Galileo constellation, but being smaller will be cheaper and faster to build and launch.

The leaders in the 2026 launch race:

38 SpaceX
15 China
5 Rocket Lab
3 Russia

SpaceX continues to lead the entire world combined in total launches, as it did in both ’24 and ’25.

Neptune as seen by Voyager-2 in 1989, four days before closest approach

2:46 pm

Neptune as seen by Voyager-2 on approach
Click for original image.

Cool image time! In two earlier posts I highlighted the pictures taken by Voyager-2 of Neptune’s two largest moons, Triton and Proteus, when it made its close fly-by of Neptune in 1989. Other than a very distant low resolution picture of 105-mile-wide Nereid, Voyager-2 took no other good images of Neptune’s other known moons.

So today, let’s begin a tour of some of Voyager-2’s imagery of Neptune itself. The picture to the right, reduced slightly to post here, was taken on August 20, 1989 as the spacecraft was beginning its approach to Neptune. It shows the full daylight hemisphere of the gas giant. From the caption:

The images were taken at a range of 4.4 million miles from the planet, 4 days and 20 hours before closest approach. The picture shows the Great Dark Spot and its companion bright smudge; on the west limb the fast moving bright feature called Scooter and the little dark spot are visible. These clouds were seen to persist for as long as Voyager’s cameras could resolve them. North of these, a bright cloud band similar to the south polar streak may be seen.

Next week I will post some of the other good shots taken of Neptune, as well as one or two close-ups of Triton that need highlighting. Sadly, at that point we will have more or less reviewed most of the best data now available of this distant world. Astronomers have used the Hubble Space Telescope in subsequent years to attempt to track its weather patterns, but even Hubble really can’t provide enough resolution to really make that research substantive.

But stay tuned. The Voyager-2 images to come are worth viewing.
