Using the ground-based ALMA telescope in Chile, astronomers have detected evidence of the existence of numerous protoplanetary disks in three molecular clouds near the galactic center.
The findings suggest that over three hundred such systems may already be forming within just these three CMZ clouds [Central Molecular Zone]. “It is exciting that we are detecting possible candidates for protoplanetary disks in the Galactic Centre. The conditions there are very different from our neighbourhood, and this may give us a chance to study planet formation in this extreme environment,” said Professor Peter Schilke at the University of Cologne.
You can read the paper here.
These results once again suggest that the formation of stars, solar systems, and planets is more ubiquitous than ever expected, that they can all form in very extreme and hostile environments, of which the center of the Milky Way is one of the most hostile.
And if planets can form here, they can likely form everywhere else. This increases the likelihood of many planets throughout the galaxy capable of supporting the development of life.
Due to the breakup of Starship over the Atlantic during its last two test flights, the FAA today issued [pdf] revised launch window and flight plan restrictions for future flights, in an attempt to placate somewhat the concerns of the United Kingdom.
The map to the right, taken from the FAA assessment, shows in red the area where air traffic is impacted by the next Starship/Superheavy launch, now tentatively planned for next week. Note how the path threads a line avoiding almost all land masses, thus limiting the worst impact to just the Bahamas, the Turks & Caicos Islands. Though the launch will effect 175 flights and require one airport on these islands to close during the launch window, to minimize the impact the FAA has required that the launch window be scheduled outside peak travel periods.
At the same time, the FAA after discussions with the governments on these islands has approved this flight plan, noting that “no significant impacts would occur” due to the ninth flight.
The agency has not yet actually issued the launch license, but it will almost certainly do so in time for SpaceX’s planned launch date. Since the advent of the Trump administration the FAA has no longer been slow walking these approvals in order to retype the results of SpaceX’s investigation. Instead, as soon as SpaceX states it has satisfactorily completed its investigation, the FAA has accepted that declaration and issued a launch license. Expect the same this time as well.
In response to reports in its local press that Russia was going to pull out of the Baikonur spaceport in the next three years, two decades before its lease expires in 2050, the Kazakhstan government yesterday issued a denial.
Local media in Kazakhstan have reported that Russia could exit the lease between 2026 and 2028 as it pulls back from international space cooperation, including a planned withdrawal from the International Space Station (ISS) as early as 2028.
“The question of early termination of the lease, or transfer of the city of Baikonur to the full control of the Kazakh side, is not being considered at this time,” Kazakhstan’s Aerospace Committee told AFP.
There rumors however could have real merit. Once ISS is retired, the Russians will have little reason to use Baikonur. It is almost certain it will not have launched its own replacement station by then, and Baikonur’s high latitude location will make its use with any other station difficult if not impossible. Moreover, the effort to switch to its Angara rocket favors launches from the Vostochny and Plesetsk spaceports, both of which have launchpads built for that rocket.
Finally, Russia has not had the cash to upgrade the launchpads at Baikonur, so much so that it has often been late paying Kazakhstan its annual $115 million rental fee, delays which at one point caused Kazakhstan to seize the launchpad Russia was upgrading for its proposed new Soyuz-5 rocket.
In fact, Russia might not be able to afford Baikonur at all, based on its present finances and the cost of its stupid war in the Ukraine.
We shall not get clarity on this story for at least a year or so, but stay tuned. Nothing is certain.
The Australian rocket startup has canceled any attempt to launch its Eris rocket during its present launch window as a result of the premature fairing release that occurred during the countdown yesterday.
Last night, during final checks, an unexpected issue triggered the rocket’s payload fairing. No fuel was loaded, no one was hurt, and early inspections show no damage to the rocket or pad.
While investigating the cause of this incident, the company will ship and install a replacement fairing from its factory. A new launch date will be announced after these actions are completed. Expect a delay of at least two months, likely more.
SpaceX this morning successfully placed another 26 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg in California.
The first stage completed its second flight, landing on a drone ship in the Pacific, and doing so only 39 days after its first flight.
The leaders in the 2025 launch race:
59 SpaceX
26 China
5 Rocket Lab
5 Russia
SpaceX now leads the rest of the world in successful launches, 59 to 43.

Cool image time! The panorama above, taken on May 14, 2025 by the left navigation camera on the Mars rover Curiosity, takes a look uphill at the canyon that the rover is now entering.
The overview map to the right gives the context. The blue dot marks the rover’s location when the picture was taken, and the yellow lines indicate approximately the view of the panorama above. If you look closely at the ground at the base of the cliff on the right, you can see the boxwork ridges indicated on the overview map.
The red dotted line marks the original planned route of the rover. The science team abandoned that plan several months ago in order to get to the boxwork geology as quickly as possible. It expects to reach that boxwork sometime in the next month or so.
Based on the proposed route posted in September 2023, after the scientists have completed their observations of the boxwork the rover will continue uphill within this canyon, bearing east as it parallels that 100-foot-high cliff seen on the horizon. The green dotted line indicates roughly that future route.
According to a NASA/JPL press release today, Perseverance successfully observed the first visible-light aurora on another world when in March 2024 it photographed a faint aurora overhead, caused by a strong solar flare.
The images at the link are quite unexciting, so much so that I don’t see a reason to include it here. The aurora observed is barely noticeable. Moreover, this is not really a new discovery. Previous observations in the ultraviolet had determined that Mars does have a weak aurora. That in rare circumstances a strong solar event can have it also appear in visible wavelengths is hardly news.
Normally I would have considered this story unimportant enough to list merely as a quick link at the end of the day, but I post it now because of how the mainstream propaganda press has latched onto it as if it is a big deal. The New York Times, the Washington Post, and the Associated Press all posted stories, giving it far more play than it deserves.
My impression from all these articles is that their reporters know almost nothing about Mars and the research that is going on there, and were easily bamboozled by the press people at NASA and JPL to report this relatively minor story loudly. They no longer have anyone who covers science and space on a regular basis and thus understand the larger context, so therefore their coverage is often shaped entirely by the public relations departments at NASA.
More proof that in today’s internet world, if you want good information the last place you should go is the old dinosaur press.
The Australian rocket startup Gilmour Space has scrubbed its first attempt to launch its Eris rocket from its own Bowen spaceport on the eastern coast of Australia.
Our team identified an issue in the ground support system during overnight checks. We’re now in an extended hold to work through it. Our next target is the Friday morning launch window.
The company has a two week launch window extending through the end of the month. If it can’t launch in that window then it will try again in the second half of June, assuming the bureaucracy of the Australian Space Agency issues a revised licence. It took that government three years to issue this license, so assuming it will work quickly to issue a revision is a dangerous thing.
The company is not providing a live stream of the launch, though it has said it will release a full video after the fact.
Norway today became the 55th nation to sign the Artemis Accords, the second nation to do so since Donald Trump assumed the presidency.
The full list of nations now part of this American space alliance: Angola, Argentina, Armenia, Australia, Austria, Bahrain, Bangladesh, Belgium, Brazil, Bulgaria, Canada, Chile, Colombia, Cyprus, Czech Republic, Denmark, Dominican Republic, Ecuador, Estonia, Finland, France, Germany, Greece, Iceland, India, Israel, Italy, Japan, Liechtenstein, Lithuania, Luxembourg, Mexico, the Netherlands, New Zealand, Nigeria, Norway, Panama, Peru, Poland, Romania, Rwanda, Saudi Arabia, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, Thailand, the United Kingdom, the United Arab Emirates, the Ukraine, the United States and Uruguay.
Unlike previous announcements, the only official public announcement (so far) was from the State Department. NASA has not yet issued its own statement. Also, and maybe far more important, unlike the previous announcement in April when Bangladesh signed, the text of the announcement made no mention of the Outer Space Treaty, as had been routinely stated during the Biden administration.
When Trump in his first term had created the Artemis Accords, the goal had been to create an American alliance of nations that supported private property and capitalism, which could also become strong enough to either get around the Outer Space Treaty’s restrictions on these concepts, or work to revise that treaty entirely to allow nations to establish such laws on other worlds. During Biden’s term that goal was abandoned. NASA announcements of new signatories would always state bluntly the exact opposite, that the accords were designed to support the Outer Space Treaty, using this language:
The Artemis Accords are grounded in the Outer Space Treaty and other agreements including the Registration Convention, the Rescue and Return Agreement, as well as best practices and norms of responsible behavior that NASA and its partners have supported, including the public release of scientific data.
Today’s State Department announcement makes no mention of the Outer Space Treaty at all, instead placing the focus on the accords’ principles of private enterprise.
With an alliance now of 55 nations (which is also likely to grow), the present Trump administration is well positioned to force some action on changing or eliminating the Outer Space Treaty’s limitations on private property and the ownership of territory on other worlds. Obviously this is not the most important item on Trump’s plate, but it does need to be addressed if Americans (and everyone else) are to have the freedom to establish colonies on other planets, protected by the same laws that protect Americans on Earth.
Hopefully the subtle language change seen today in this State Department press announcement is a signal that the Trump administration intends to do so.
UPDATE: It appears that NASA still wants this alliance to uphold the Outer Space Treaty. Late today it released its own press release announcing Norway’s signing, and included the boilerplate that I quote above that it began using during the Biden administration.
I wonder when (or if) Marco Rubio or any of the higher ups in the Trump administration (including Trump) will ever take an interest in this issue. So far it does not appear they have.
NASA and Axiom have delayed the launch of the company’s fourth commercial manned flight to ISS by at least a week, from May 29 to June 8, at the earliest.
The NASA press announcement was decidedly vague about the reason:
After reviewing the International Space Station flight schedule, NASA and its partners are shifting launch opportunities for several upcoming missions. The schedule adjustments provide more time to finalize mission plans, spacecraft readiness, and logistics.
This report speculates that SpaceX might have had additional issues getting its brand new manned Dragon capsule ready on time, without out any clear evidence. The capsule has taken longer to build than originally predicted, but giving SpaceX one extra week seems insufficient if the capsule had some outstanding technical issues.
More likely it is exactly as NASA states, the delay is to accommodate the complex coming and going of vehicles to ISS.
The mission will launch one Axiom command pilot and three passengers, government astronauts from India, Poland, and Hungary.
This new manned Dragon, as yet unnamed, will bring SpaceX’s fleet of manned capsules to five, assuming it does not retire one of the older capsules. The company will thus have the largest manned spacecraft fleet ever, exceeding NASA’s four shuttle fleet that existed in the 1990s.

The routes the Voyager spacecraft have
taken since launch. Not to scale.
Because of an anticipated pause in communications due to upgrade work on the antennas of NASA’s Deep Space Network — used to communicate with interplanetary missions — the engineers operating the two Voyager spacecraft that are now in interstellar space after almost a half century of travel have improvised a repair that reactivated thrusters on Voyager-1 that were deemed inoperable in 2004.
Since then the spacecraft had been dependent solely on its backup thrusters. The engineers wanted the spacecraft to have two sets of thrusters again in case something went wrong during that pause in communications, running from May 2025 to February 2026.
The repair required getting two heaters switched back on, and carried with it the risk of an explosion that would destroy Voyager-1. The command to reactivate the heaters was sent on March 20, 2025, and two days later (after the command traveled at the speed of light for 23 hours to reach Voyager-1 and then 23 hours to return) the spacecraft signaled that all was well and that the heaters and thrusters were now working again.
Both Voyagers are expected to run out of power sometime in the next two years. The goal now is try to make both last at least until 2027, so that they will mark a full half century of operation since their launch in 1977.
Even though the newly minted town of Starbase at Boca Chica is essentially a “company town,” with almost all its residents employees of SpaceX, the company is not treating the town in a traditional company town manner, which in the past meant the company used its monopoly control to the detriment of its employees.
Instead, it appears SpaceX is committing millions to develop the town of Starbase at Boca Chica into a very classy place to live.
The newly minted Starbase, Texas will soon have a $22 million community center, according to online records from the Texas Department of Licensing and Regulation. The community center is being designed by a Pennsylvania design firm called AE7, and will be located at 41028 Quicksilver Ave. immediately north of a bend in the Rio Grande. It will include a 20,000-square-foot building and pool, with construction aiming to start in June and be completed by June 2026, according to the TDLR records.
…Earlier this year, Starbase officials registered several other community projects with state regulators, including a $20 million school “housing children from infancy to grade 12,” whose construction was set to get underway in April. Other projects include a 2,555-square-foot medical clinic, a $2 million multifamily construction featuring a 111,745-square-foot “new parking garage and multifamily” development at 52163 Memes St.
SpaceX is also building a $100 million office building for its operations. It has also filed plans to create a $13.5 million recreation center and sushi restaurant. Another plan to build a $15 million retail plaza was proposed earlier, but has remained stalled.
Under the leadership of Elon Musk (“the new Hitler” according to the brainless Democratic Party and its media propagandists), the employees of SpaceX at Starbase will be living in an up-to-date modern and very upper middle class environment, comparable to the best suburban communities found anywhere in the United States.

Using data from both ground- and space-based telescopes, astronomers have now observed clouds rising in the thick atmosphere of the Saturn moon Titan.
The team observed Titan in November 2022 and July 2023 using both Keck Observatory and the James Webb Space Telescope. Those observations not only showed clouds in the mid and high northern latitudes on Titan — the hemisphere where it is currently summer — but also showed those clouds apparently rising to higher altitudes over time. While previous studies have observed cloud convection at southern latitudes, this is the first time evidence for such convection has been seen in the north. This is significant because most of Titan’s lakes and seas are located in its northern hemisphere and evaporation from lakes is a major potential methane source. Their total area is similar to that of the Great Lakes in North America.
The image to the right shows these methane clouds, indicated by the arrows, as seen by Webb on July 11, 2023 and then three days later by Keck. The clouds appear to have shifted downward during these observations.
The data suggests we are seeing one small aspect of Titan’s atmospheric methane cycle, where the liquid methane in the lakes evaporates to form clouds, which later than condense to rain back down. Though superficially similar to the water cycle here on Earth, the details suggest it will be very different on Titan.
Two launches so far today. First, China successfully launched the first 12 satellites for proposed orbiting computer constellation dubbed the “Three-Body Computing Constellation,” its Long March 2D rocket lifting off from its Jiuquan spaceport in northwest China.
As is usual for China’s state-run press, it revealed little useful information about this constellation.
Each satellite in this initial batch is equipped with a domestically developed 8-billion-parameter AI model capable of processing satellite data across levels L0 to L4 (with L0 referring to raw data directly collected by the satellite), CGTN learned from the lab. The constellation also supports full inter-satellite connectivity. In addition to AI-powered data processing, the satellites will carry out experimental missions, including cross-orbit laser communication and astronomical science observations.
The press also provided no information about where the rocket’s lower stages, using very toxic hypergolic fuels, crashed inside China.
Next, SpaceX placed another 28 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral in Florida. The first stage completed its fourth flight, landing on a drone ship in the Atlantic.
The leaders in the 2025 launch race:
58 SpaceX
26 China
5 Rocket Lab
5 Russia
SpaceX still leads the rest of the world in successful launches, 58 to 43.
Though it did not state the all the specific rockets the company will use, the satellite-to-cellphone company AST SpaceMobile revealed this week that it plans to launch its BlueBird satellites every month or two beginning in July 2025.
India’s GSLV rocket is slated to carry AST SpaceMobile’s first Block 2 BlueBird satellite, which the operator said is scheduled to ship from its Texas facility in June. At three times the size of each of the five Block 1 BlueBirds launched last year on a SpaceX Falcon 9 rocket, the satellite would surpass its predecessors to become the largest commercial antenna ever deployed in low Earth orbit.
Abel Avellan, AST SpaceMobile founder and CEO, said that from the second or third launch this year, Block 2 BlueBirds would feature in-house developed chips to support peak data rates of up to 120 megabits per second at 10 times the capacity of Block 1. Subsequent launches would also deploy between three and eight Block 2 satellites at a time, depending on the rocket, Avellan told investors during the company’s earnings call.
Avellan did not give an update on other launch missions that would leverage SpaceX’s Falcon 9 and Blue Origin’s New Glenn rockets, whose larger fairings can accommodate up to eight Block 2 satellites per flight.
Whether AST SpaceMobile will be able to fulfill this schedule however is a big question. SpaceX could provide the rockets for all these launches, but the availability of its Falcon 9 rocket might be limited due to other customer contracts as well as its own needs to launch Starlink satellites. Blue Origin’s New Glenn could certainly use the business, but that rocket has only launched once, and the company has been very slow about doing its second launch, now scheduled for later this month. It is very unclear whether it could do more than one of these launches this year.
India’s GSLV rocket could grab the business, but once again it is unclear it has the capacity to do more than two such launches before the end of the year.
All in all, it appears the demand for rocket launches exceeds the supply, a situation that is very good for the launch industry.
Varda’s third capsule, on the ground in Australia.
Click for original image.
The third recoverable capsule for the startup Varda has landed successfully in Australia, completing its commercial orbital mission for the Air Force, which tested a positional sensor intended for use during hypersonic missile flights.
The California-based space manufacturing startup said the capsule, carrying an inertial measurement unit (IMU) developed for the U.S. Air Force by Innovative Scientific Solutions Incorporated (ISSI), touched down at the Koonibba Test Range operated by Southern Launch.
According to company officials, the capsule reentered Earth’s atmosphere at speeds exceeding Mach 25 – more than 25 times the speed of sound. “This extreme environment offers researchers valuable data to enhance hypersonic navigation, expand orbital economy applications, and support U.S. national security objectives in low Earth orbit,” said Dave McFarland, Varda’s vice president of hypersonic and reentry test.
The capsule had been launched on March 14, 2025 on a SpaceX Falcon 9. Of the capsule’s now three flights, two have tested equipment sensors during descent. Only the first did in-space manufacturing, as had been what Varda anticipated would be its primary customer base.
This was also the second return in a row landing in Australia. Initially the company had planned to return the capsules in the U.S., as it did with its first capsule, but the bureaucratic red tape from both the FAA and the military to do that landing was so bad (delaying the capsule’s return by six months) Varda made alternative arrangements in Australia.
In the past two days SpaceX’s Starlink constellation for providing internet service globally has obtained approvals from three different countries, widening its use significantly worldwide.
First, Scotland has approved Starlink to begin a six-month trial whereby the constellation will provide internet access on trains operating “between Inverness and Thurso, Wick, Kyle of Lochalsh and Aberdeen.” If successful, the program will be expanded to provide service along other rural train lines in Scotland.
Next the Bangledesh government approved a 90-day waiver allowing Starlink to “supply bandwidth from outside the country.” Normally the regulations in that country require such services to be routed through “local gateways”, which likely refers to local communications companies. This waiver will allow SpaceX to offer Starlink in its normal manner, direct to the customer and outside any already established communications network.
Whether the waiver will be extended further is at present unknown, but I suspect it will be because of public pressure.
Finally, Elon Musk announced that Saudi Arabia has now approved Starlink for “aviation and maritime use” within the country.
All in all, SpaceX continues to vacuum up the world’s internet market simply because none of its competitors have made the effort to compete aggressively. They continue to cede territory to Starlink, without a fight.

Scientists reviewing the dust devil tracks in orbital images produced by Mars Reconnaissance Orbiter (MRO) have now created a global map that also provides insight into the ground conditions that cause the dust devils to form. From the abstract:
In the first global study of these tracks using high-resolution satellite images from 2014 to 2018, we find tracks in 4% of the images, mostly near 60° north and south latitudes. These tracks are more common during local summers, especially in the southern hemisphere, coinciding with the peak of Mars’ dust storm season, when active dust devils are also more common. Surprisingly, dust devil track (DDT) formation does not depend on elevation, indicating it is not related to the ambient atmospheric pressure. Instead, they occur in darker areas where surface dust covers coarser material, which is revealed as the dust devil moves past.
The white dots on the map above, figure 5 of the paper, shows those MRO images where dust devil tracks were seen. The redish-orange regions are where the data suggests more dust devils should occur, while the blue areas of regions of few dust devils.
The map also notes the locations where Spirit, Opportunity, and InSight landed. Opportunity clearly landed in a region that had more dust devil activity, which explains why its solar panels were cleaned off so regularly by wind. Spirit did not land in such a region, but somehow it was lucky in getting wind events that cleared its panels of dust. InSight had no such luck, and having landed in a region with little dust devil activity, its panels steadily became covered with dust, eventually forcing the end of the mission.
As the paper notes, “To maximize mission lifetimes, future solar powered assets should favor regions where we have identified numerous [dust devil tracks] and where many active [dust devils] are present.” This proposal makes sense, for many reasons. For one, it shifts missions to higher latitudes where many glacial and near-surface ice features are found. Up until now the science community has sent all the landers and rovers to the Martian dry tropics, which has no such near surface ice. For future colonies it is imperative we begin studying Mars’ wetter regions.
This study provides another practical reason for doing so.
Dry ice frost on Martian cliffs. From a 2020 post.
Click for full image.
A new analysis of the gullies found on cliffs on Mars, usually on the interior rims of craters, has concluded that carbon dioxide frost is the cause of the erosion, not ancient flows of water.
This conclusion eliminates the need for liquid flowing water in the Martian past, at least in conjunction with gullies. From the paper’s conclusion:
These results show that CO2 frost is capable of producing Martian gully morphologies. Since flows powered by this process are known to be ongoing and capable of transporting the necessary volume of material, it is the simplest explanation for their formation. Variations in the frequency and fluidity of flows could have occurred over time due to variations in the CO2 cycle. CO2-driven gully formation would indicate that there was not necessarily regular, recurring meltwater during high-obliquity periods. This removes a constraint on recent climate, and also addresses a paradox: if obliquity regularly exceeds the current value as generally thought, and if gullies formed via snow melting at high obliquity, the Late Amazonian Epoch should have included regular snowmelt and widespread aqueous processes. Gully formation by CO2 frost processes is consistent with a cold-desert Late Amazonian with rare or small amounts of liquid water and little aqueous weathering, consistent with the observed mineralogy.
…Gullies, one of the most-discussed lines of evidence for liquid water on Mars, may in fact have no direct connection to H2O. CO2 frost-fluidized gully formation also has broader implications for geomorphology, widening an emerging field of new landform types and processes without Earth analogs. Similar processes could occur on other worlds with erodible substrates on steep slopes and volatile ices at their frost point, although we currently lack the high-resolution images needed to test this hypothesis. Such ices include N2 on Pluto and Triton, and SO2 on Io. [emphasis mine]
In other words, though the gullies appear at first glance to our Earth eyes to have been caused by water flowing downhill, in fact the data now suggests the annual CO2 frost cycle of Mars is the prime cause, even in the distant past. No surface water was required. And since no one has yet come up with a good model for liquid surface water even existing in the Martian past (the atmosphere being too cold and thin), this conclusion helps eliminate this conflict.
The paper also notes the lack of water likely eliminates the need for any planetary protection efforts at these gullies, as the lack of water makes the likelihood of any microbiology nil.
As these conclusions are based on lab work and analysis of images, there remains great uncertainty. Nonetheless, the results help reinforce the arguments that the geological features we see on Mars were formed not by flowing liquid water but by other processes, such as glaciers of ice.

Australia’s commercial spaceports. Click for original map.
After several years of delays, the Australian rocket startup Gilmour Space today announced that it has finally been issued a launch license from the Australian Space Agency.
According to the company, “pending weather & final system checks, we’re on target for our launch window to open NET May 15.”
The launch will take place at Gilmour’s own Bowen spaceport on the east coast of Australia. The Eris rocket has three stages and is designed to launch smallsats similar to Rocket Lab’s Electron rocket.
It is amazing this company hasn’t gone bankrupt waiting for this launch license. It applied in 2022, hoping to launch that year. Three years later it finally gets the okay. The amount of cash it had to burn unnecessarily in those years would generally destroy most startups.
Whether the red tape in Australia will clear up in the future is decidedly unknown, especially with the election victory this month of the leftist party.

China early this morning successfully launched another communications test satellite. its Long March 3C rocket lifting off from its Xichang spaceport in southwest China.
China’s state-run press as always released little information. All we really know is that this launch has been part of a series of recent launches putting similar communications test satellites into orbit. We also don’t know where the rocket’s lower stages, which use very toxic hypergolic fuels, crashed inside China.

Capitalism in space: In its effort to rely on the private sector for its space needs, the Pentagon yesterday added fourteen space companies to its list of eight companies that can bid on space infrastructure projects.
The latest round of companies added to the project includes Capella Space, EdgeCortix, Eutelsat America Corp. OneWeb Technologies, Fairwinds Technologies and AST Space Mobile, Illumina Computing Group, Lockheed Martin Space, MapLarge, SES Space & Defense, Skycorp, SkyFi, Ursa Space, and Viasat.
They join eight other firms that were brought on board in 2022: Aalyria Technologies, Amazon Web Services, Amazon Kuiper, Anduril, Astranis, ATLAS Space Operations, Enveil, Google, Palantir, Planet Labs, Microsoft, and SpiderOak.
Essentially, the Pentagon wants these companies to compete for contracts to build various space-based communications assets, coming up with the designs and spacecraft themselves. In this round the specific goal is to develop satellite systems that can transmit data and communications to military units anywhere on the globe.
It is puzzling however that SpaceX is not included in this list, even though all its competitors are. I suspect this is because SpaceX’s Starshield version of Starlink is covered under different military programs and contracts. Or it could be that politics forced the military to exclude it in this case. Or there could be some other reason that defies logic. Understanding the byzantine workings of the government’s bureaucracy is often impossible.
In its most recent fund-raising round, the solid-fueled rocket startup X-Bow (pronounced “crossbow”) raised $35 million in private investment capital, with Lockheed Martin being the largest investor.
Lockheed Martin’s involvement marks a deepening interest in securing alternative sources for solid rocket motors, components that are increasingly vital to a wide range of U.S. missile systems, including hypersonic weapons. The investment comes three years after Lockheed’s attempt to acquire Aerojet Rocketdyne was blocked by the Federal Trade Commission on antitrust grounds. Aerojet was later bought by L3Harris Technologies, leaving Lockheed without a vertically integrated propulsion supplier.
Nor is this the first time that Lockheed Martin has invested in a rocket startup. It had previously invested in ABL and Orbex, both liquid-fueled but struggling or failing, as well as the much more successful Rocket Lab. It has also invested in the orbital tug startup Orbit Fab, the orbital capsule company Inversion Space, and the satellite startup Terran Orbital, which it ended up buying entirely.
All in all, Lockheed Martin appears determined to join the new wave of space startups, if not by doing it itself but by buying into the successes of new startups. So far this has not entirely paid off, but it does appear to be, in the long term, a viable strategy to keep Lockheed Martin competitive and in the game.
Flight path of second super pressure balloon test
Due to an issue with its power system, NASA engineers today decided to end its second super pressure balloon flight this year after only nine days, when the balloon crossed over South America and thus allowing them to recover it safely.
Although the balloon performed well and the mission successfully met its minimum requirements toward qualification of the balloon system, an issue with the power system aboard the balloon gondola prompted the team to terminate the mission early as a precaution. The team had been monitoring a power failure in one of the redundant charging systems since May 8. “Despite the loss of one of the redundant charging systems, the remaining power system was performing very well and still able to sustain the batteries and electrical equipment over the course of the mission,” said Hamilton. “However, to be cautious, the team opted to end the flight early to get the equipment back, so we can do a full failure analysis.”
After identifying a safe area and coordinating with Argentinian officials, the flight was safely terminated. Recovery of the balloon and payload is in progress.
The first flight flew for seventeen days, circling the globe at the high southern latitudes. In that case issues with the balloon caused the flight to be terminated while it was over the ocean, preventing recovery. As the goal with both flights was to fly for 100 days, neither came close to that target.
