Axiom today announced it has signed a deal with the medical company Burjeel Holdings to fly and test a glucose monitor during its May 2025 AX-4 manned mission to ISS.
The Ax-4 mission will utilize Continuous Glucose Monitors (CGMs), which have become the standard for glucose monitoring in individuals with diabetes. These devices will be tested to ensure their accuracy in microgravity, providing real-time data that will ultimately support the health of astronauts with insulin-dependent diabetes.The comprehensive preflight, inflight, and post flight protocols will employ various testing methods to validate these technologies. The Ax-4 mission also plans to look at insulin exposure in microgravity to assess the potency and stability of the drug product upon its return to Earth.
Testing the behavior of CGMs and insulin delivery technologies in microgravity and with circadian rhythm disruption is expected to advance the understanding of how such innovations can improve diabetes monitoring and care in remote or under served areas on Earth. Experts say this research will lay the groundwork for managing diabetes in isolated locations, such as oil rigs, deserts, or rural regions.
These tests will also make it possible for people who have diabetes to go into space. For Axiom, this will help widen its customer base. For Burjeel it proves its monitors can work in many remote and hostile environments, also widening its customer base.

Cool image time! Using Mars Reconnaissance Orbiter (MRO), scientists have captured a very cool image of Curiosity in its recent travels on Mars. That picture is above, reduced and sharpened to post here.
Taken by the HiRISE (High-Resolution Imaging Science Experiment) camera aboard NASA’s Mars Reconnaissance Orbiter, the image shows Curiosity as a dark speck at the front of a long trail of rover tracks. Likely to last for months before being erased by wind, the tracks span about 1,050 feet (320 meters). They represent roughly 11 drives starting on Feb. 2 as Curiosity trucked along at a top speed of 0.1 mph (0.16 kph) from Gediz Vallis channel on the journey to its next science stop: a region with potential boxwork formations, possibly made by groundwater billions of years ago.
The overview map to the right provides some context. Curiosity’s present position is indicated by the blue dot. The yellow lines indicate the approximate section of its past travels photographed by the picture above.
According to the press release at the link, the science team is now estimating the rover will arrive at the boxwork geology in about a month.
The smart phone: A proven tool for spying
Just one more reason I don’t own a smartphone: Researchers have now found that though there is no evidence that big software companies like Facebook and Google are tracking your smartphone conversations, the data instead shows that the many apps you routinely install on your phone are spying on you quite extensively by periodically taking screenshots of things you look at and sending those images to third parties.
“There were no audio leaks at all – not a single app activated the microphone,” said Christo Wilson, a computer scientist working on the project. “Then we started seeing things we didn’t expect. Apps were automatically taking screenshots of themselves and sending them to third parties. In one case, the app took video of the screen activity and sent that information to a third party.”
Out of over 17,000 Android apps examined, more than 9,000 had potential permissions to take screenshots. And a number of apps were found to actively be doing so, taking screenshots and sending them to third-party sources. “That has the potential to be much worse than having the camera taking pictures of the ceiling or the microphone recording pointless conversations,” said David Choffnes, another computer scientists working on the project. “There is no easy way to close this privacy opening.”
Doing this kind of spying is simply unethical, but it is also now routine in our increasingly unethical culture. What makes it worse is that I expect few will react in any way to this information. People will shrug and continue to install apps casually, accepting the fact that they are now merely a tool that someone else can manipulate.
The smallsat rocket startup MaiaSpace has selected Poland’s Łukasiewicz Research Network’s Institute of Aviation to develop the engine that will power its Maia rocket’s top stage, used to put satellites into their final orbit.
In a 23 April update, the Łukasiewicz Research Network’s Institute of Aviation (Łukasiewicz–ILOT) announced that it had been selected by MaiaSpace to develop a rocket engine to power Maia’s Colibri kick stage. According to the announcement, the engine will be based on technology developed by Łukasiewicz–ILOT as part of its Green Bipropellant Apogee Rocket Engine (GRACE) initiative, a project financed by the European Space Agency under the Future Launchers Preparatory Programme.
Each new engine will be capable of producing 420 newtons of thrust, with a cluster of these engines powering the Colibri kick stage. However, the update did not specify how many engines would make up the cluster
MaiaSpace had previously indicated it was building its own Colibri kick stage engine. It appears that it has now decided to hire Lukasiewicz to do it instead.
The significance here is not this specific decision, but how it involves two different European commercial entities with no managerial input from the European Space Agency or any government agency. It really does appear that Europe’s aerospace industry has completely freed itself from the dictates of those government apparachiks.
MaiaSpace hopes to complete the first launch of Maia in 2026.
Schmidt’s data tampering, as documented in 2016.
As part of the Trump administration’s aggressive effort to trim the federal budget as well as shift the research focus at the federal government’s many science agencies, on April 24, 2025 it revealed that it has canceled the building lease for the Goddard Institute for Space Studies (GISS) in New York that has existed since 1961 and in 2016 and 2017 was found to be tampering with past climate data with no explanation, lowering past temperature numbers while raising more recent ones in order to make the data fit the as-yet unproven theory that human activity is causing global warming.
Those “adjustments” have never been justified in any way. Nor has Gavin Schmidt, the man who heads GISS, ever done anything to correct them. Moreover, when his office was accused of this tampering in 2016 he not only refused to fix or justify the changes, he responded by claiming “planetary warming does not care about the election.” In the years since it has been his office that annually declares each year “the hottest on record,” using these tampered numbers to do so and demonstrating that he has been acting not as a real researcher but as a political operative of the global warming crowd.
Though the office lease is being canceled, GISS has not been shut down, as of now.
While NASA is terminating the lease on the GISS offices, it is not closing the institute itself. Lystrup said in the email that it will help employees move “to remote work agreements in the short-term as the agency seeks a new, permanent space for the team.”
I suspect this statement is merely designed by Trump officials to dampen the screams of opposition against its actions. It is very likely GISS is going away, and most of its employees will have to find new jobs.
The hope is that new scientists can be hired to review these tampered numbers and get them fixed so that climate research in the future can proceed with reliable data.
SpaceX tonight successfully launched another 28 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.
The first stage completed its 23 flight, landing on a drone ship in the Atlantic.
The leaders in the 2025 launch race:
47 SpaceX
21 China
5 Rocket Lab
5 Russia
SpaceX now leads the rest of the world in successful launches, 47 to 36.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was released today by the science team running the Dark Energy Camera on the Blanco 4-meter telescope in Chile.
This winding, shadowy form, accentuated by a densely-packed starry background, is the Circinus West molecular cloud — a region rich in gas and dust and known for its host of newly formed stars. Molecular Clouds, the cradles of star formation, are interstellar clouds that are so dense and cold that atoms within them bond with each other to form molecules. Some, such as Circinus West, are so dense that light cannot pass through, giving them a dark, mottled appearance and earning them the name dark nebulae. The cloud’s flourishing population of young stars has offered astronomers a wealth of insight into the processes driving star formation and molecular cloud evolution.
…Circinus West is known for harboring dozens of young stellar objects — stars that are in their early stages of development. Despite being shrouded in dense gas and dust, these infant stars make themselves known. Zooming in, various clues to their presence can be seen dotted throughout Circinus West’s snaking tendrils.
The cloud is about 2,500 light years away and is estimated to be about 180 light years across. Scientists estimate the mass in the cloud to be about 250,000 times that of the Sun.
No one however would ever even know this cloud existed if it wasn’t back dropped by thick field of stars behind it.
Landing sites for both Firefly’s Blue Ghost and
Ispace’s Resilience
The Japanese startup Ispace today announced that its Resilience lunar lander — launched on a Falcon 9 to the Moon in January — has now completed all the orbital maneuvers required to send it on a path to enter lunar orbit in early May.
Ispace engineers performed the final orbit maneuver from the Mission Control Center in Nihonbashi, Tokyo, Japan in accordance with the mission operation plan. In total, the RESILIENCE lunar lander has completed 8 orbit control maneuvers. RESILIENCE is now maintaining a stable attitude in its planned orbit and mission operations specialists are now preparing for the Mission 2 milestone Success 7, “Entering Lunar Orbit.” The RESILIENCE lander is expected to enter lunar orbit on May 7, 2025.
The map to the right shows the landing zone, near the top of Moon’s near hemisphere in the region of Figoris Mare. The landing will occur a week or so after orbital insertion, after the company’s engineers have fully assessed the situation.
The rover carries eight commercial payloads, including its own Tenacious mini-rover, as well as a “water electrolyzer” from a Japanese company, a “food production experiment” from another company, and a “deep space radiation probe” from the National Central University of Taiwan.
Resilience’s main purpose however remains to prove the company can build and successfully soft land on the Moon. Its only previous attempt, Hakuto-R1, crashed in Atlas Crater. Despite that failure Ispace has won a contract each from NASA and Japan to launch additional lunar landers, so a success here is critical for the company’s future.

As part of a larger European Space Agency (ESA)) project, Viasat has won an ESA contract to build a communications constellation that will orbit the Moon.
Viasat will be responsible for the design and development of the communication network and will lead the definition of the end-to-end communications services: aiming to provide a communications network for lunar landers, rovers, orbiters, and other technology. Viasat will also be responsible for the communication earth ground infrastructure and communication lunar surface user terminals. Telespazio, as Moonlight program lead, has executed a contract with Viasat for the initial design phase of the communication system. This work will be fully funded by the European Space Agency throughout Phase 1.
The UK Space Agency, as one of the major contributors to ESA’s Moonlight program, selected Viasat to lead the UK ecosystem to deliver the communications capability. Moonlight services will be deployed in phases, targeting initial capability at the end of 2028 with full operations aimed by 2030.
It does seem that there are a lot of competing communications/navigation constellations under development, from China, Europe, and the U.S. It also appears that there is far less coordination between them then there should be.

The original phase I plan of Chinese-Russian lunar
base plan, from June 2021.
The new colonial movement: In several different reports today in China’s state-run press — timed to coincide with the launch of three astronauts to Tiangong-3 — Chinese officials confirmed that it has moved up the planned launch dates for both its first lunar rover as well as its Mars sample return mission, and it is also expanding its offers to the international community to partner on those missions.
At the same time it let slip the fact that it will not be establishing its lunar base on the Moon in 2030, as previously claimed. Moreover, note how this so-called accelerated schedule of lunar missions is actually behind the announced timetable outlined by China and Russia in 2021, as shown on the right. None will fly by this year, as promised.
As for the news today, first China announced that its Tianwen-3 Mars sample return mission will launch in 2028.

Proposed spaceports in Malaysia
According to an report out of Malaysia yesterday, the Malaysian state of Pahang has initiated a one year study to build a spaceport off its eastern coast near the town of Nensasi, working in partnership with China.
“On April 15, PKNP [Pahang State Development Corporation] signed a letter of intent with China Great Wall Industry Corporation (CGWIC) and Lestari Angkasa Sdn Bhd to establish a strategic collaboration in the space technology sector. “Next month, PKNP and Lestari Angkasa will visit Wenchang Space City in Hainan, China, to hold further discussions on the Pahang International Spaceport project,” he said during the Pahang state assembly session today.
This is the second Malaysian state to propose its own spaceport. In January the eastern state of Sabah began its own study, working in partnership with the Ukraine.
The partnership with China is worrisome for the U.S., as it is very likely that China will arrange use of that spaceport for its own purposes. It will also use its presence there to access and steal any technology brought by other western companies or nations should they launch there as well.
China today successfully launched a new crew of three astronauts for a six-month mission on its Tiangog-3 space station, its Long March 2F rocket lifting off from its Jiuquan spaceport in northwest China.
The crew’s Shenzhou capsule will dock autonomously with the station later today. This was China’s fifteenth manned mission and ninth to the station, which it has now occupied continuously for more than three and a half years.
The rocket’s core stage and four strap-on boosters crashed somewhere inside China. No word on where or whether they crashed near any habitable areas.
The leaders in the 2025 launch race:
46 SpaceX
21 China
5 Rocket Lab

SpaceX now leads the rest of the world in successful launches, 46 to 36.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on February 28, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).
The scientists label this picture “enigmatic terrain.” And there are certainly mysteries here. For example, why are there scattered tiny knobs across the surface in the low areas, but not on the higher areas? Also, what caused that top layer to get stripped in places? Was it erosion from wind? Or did some other process cause that layer to vanish in these spots?
Note too that this landscape has few craters. Whatever happened here occurred recently enough that it was able to cover over the impact history from the early solar system that peppered the planets with craters as the planets formed. Though impacts continue even to this day, the impact rate is far less, which allows younger terrain like this to remain largely crater free.
The location provides us some answers, but it still leaves much of this geology a puzzlement.

In a set of new pictures taken of Curiosity’s wheels yesterday it appears that the damage to those wheels has increased significantly in the past year, with the most damaged wheel (which based on contradictory science team reports is either the middle left or middle right wheel), having more had more sections broken to the point where this wheel might even fail in the near future.
The pictures to the right show these changes. The treads, called grousers, have been numbered to make the comparisons easier. The bottom two pictures were taken in September 2024, and look at this wheel with the damage on the side to show how a whole section of the wheel had at that time collapsed to form a depression.
The top two pictures show the increase in the damage in this section between February 2024 and yesterday. Note especially the changes in growlers 4, 5, and 6. Not only have large sections broken off in the wheel’s central section, it appears that the wheel’s outside section is beginning to separate from that central section.
The increased damage in the past year illustrated starkly the roughness of the terrain that the rover is traversing. Moreover, there is no sign that roughness is going to ease anytime in the near future. This increased damage thus explains partly why the science team changed the rover’s route to get to the nearby boxwork geology as fast as possible. That unique geology is likely to provide some important scientific information unobtainable elsewhere, and it seems worthwhile to get to it before this particular wheel fails.
There is one silver lining to this cloud. This particular wheel is a middle wheel, which means it is less critical to maintaining the rover’s stability as it travels as well as sits. The photographs of the other wheels taken today do not show as much change. Even if this wheel fails, the rover will still have five working wheels, including the most essential four corner wheels.
Having shut down its smaller Rocket-3 rocket operations and then almost going bankrupt, the startup Astra is apparently coming back from the dead, having won a $44 million military development contract to build its larger Rocket-4 rocket.
Chris Kemp, Astra’s chief executive, said in an interview the company intends to leverage its contract with the Defense Innovation Unit to demonstrate point-to-point delivery of about 1,300 pounds of cargo using Rocket 4. The military for years has expressed interest in using rockets for rapid deployment of critical supplies to remote locations, complementing traditional transportation methods.
The company now claims it will do the first test launch of Rocket-4 in 2026.
When the company’s stock valuation dropped so much in 2022 and was on the verge of shutting down, Kemp and a team of investors purchased that stock and took the company private. Since then it has mostly focused on building attitude thrusters for satellites. Whether this new contract is enough to get this new rocket off the ground remains a big unknown.
Astronomers using the TESS space telescope have discovered an exoplanet about 140 light years away that appears to have a tail of trailing material that is gaining mass with each transit as the planet slowly disintegrates.
The typical signal of an orbiting exoplanet looks like a brief dip in a light curve, which repeats regularly, indicating that a compact body such as a planet is briefly passing in front of, and temporarily blocking, the light from its host star.
This typical pattern was unlike what Hon and his colleagues detected from the host star BD+05 4868 A, located in the constellation of Pegasus. Though a transit appeared every 30.5 hours, the brightness took much longer to return to normal, suggesting a long trailing structure still blocking starlight. Even more intriguing, the depth of the dip changed with each orbit, suggesting that whatever was passing in front of the star wasn’t always the same shape or blocking the same amount of light.
You can read the peer-reviewed paper here [pdf]. Their calculations estimate the planet will disintegrate entirely in about two million years.
Because of the nature of these transits, the relative nearness of the star system, and the existence of this tail of material, this exoplanet is an excellent candidate for studying the planet’s structure and make-up. The scientists advocate further studies using a range of telescopes, including Webb and Hubble.

Both Jay and I have found it to be a relatively slow news day in space.
According to the budget data that was leaked anonymous last week, the Trump administration is proposing a major restructuring of NOAA’s satellite operations, shifting from building geosynchronous weather/climate satellites in partnership with NASA to focusing on buying weather data from commercial smallsats.
The plan would initially reduce NOAA’s program by two-thirds.
The document suggests NOAA’s National Environmental Satellite, Data and Information Service (NESDIS) “immediately cancel all major instrument and spacecraft contracts on the GeoXO program,” saying the projected costs are “unstainable, lack support of Congress, and are out of step with international peers.”
GeoXO is a $19.6 billion program that includes six satellites and ground infrastructure to significantly enhance NOAA’s ability to monitor weather, map lightning, and track ocean and atmospheric conditions over decades. To maintain observations from geostationary orbit at the conclusion of the Geostationary Operational Environmental Satellite (GOES)-R Series, the White House memo calls on NOAA to “immediately institute a major overhaul to lower lifecycle costs by 50 percent” with annual costs below $500 million, while remaining on schedule to launch the first satellite in 2032.
Rather than expanding the geostationary constellation to include satellites over the East, West and Central United States, the proposal includes only East and West satellites like the GOES-R Series. OMB also recommends an immediate end to NOAA relying on NASA to help it acquire weather satellites.
Maybe the most controversial recommendation calls for NOAA to focus on gathering daily weather data while ending its monitoring of long term ocean and atmospheric climate trends.
The shift from NOAA-built satellites to purchasing weather data from commercially launched and built satellites makes great sense, and is the most likely part of this plan to get implemented. Similarly, ending NOAA’s reliance on NASA will help streamline the fat from both agencies.
Whether the Trump administration can force an end to NOAA’s climate gathering operations is less clear. The politics suggest this will be difficult. The realities however suggest that a major house-cleaning in this area is in order, as there is ample evidence that the scientists running this work have been playing games with the data, manipulating it in order to support their theories of human-caused global warming.
Going where no bureaucrat has gone before! Ceremonies on April 20, 2025 in Cairo inaugurated the opening of the headquarters in Egypt of the African Space Agency.
Badr Abdelatty, Egypt’s Minister of Foreign Affairs and Immigration, participated in the official inauguration. The ceremony was attended by several high-ranking officials and dignitaries, including Dr. Ayman Ashour, Minister of Higher Education and Scientific Research; Dr. Sherif Sedky, CEO of the Egyptian Space Agency; Moses Vilakati, African Union Commissioner for Agriculture, Rural Development, Blue Economy, and Environmental Sustainability; and Dr. Tidiane Ouattara, Chair of the African Space Agency Council. Also in attendance were heads and representatives of African and international space agencies, along with ambassadors from African nations and partner countries of the African Union.
…Minister Abdelatty underlined that the African Space Agency will act as a platform to deepen cooperation among African nations in the peaceful uses of space, promote knowledge exchange, and build technical capacities. Additionally, it will work to unify African positions in international forums, especially within the United Nations system. He also stressed the importance of collaboration with academic institutions, research centers, and global space agencies, which will help establish a robust African presence in space science and technology.
While these officials also claimed the agency will foster cooperation across Africa’s space industries and governments, the quote reveals its main focus, acting as a jobs program for the political hacks who have done favors for the various leaders of African countries. This is not to say it won’t help encourage some space development (it will), but we must recognize that this agency has little to do with fostering private enterprise.
Closest view of asteroid DonaldJohanson.
Click for movie.
The science team for the asteroid probe Lucy today released the pictures taken by the spacecraft as it approached the asteroid Donaldjohanson on April 20, 2025, compiled into a short movie.
The asteroid was previously observed to have large brightness variations over a 10-day period, so some of Lucy team members’ expectations were confirmed when the first images showed what appeared to be an elongated contact binary (an object formed when two smaller bodies collide). However, the team was surprised by the odd shape of the narrow neck connecting the two lobes, which looks like two nested ice cream cones.
…From a preliminary analysis of the first available images collected by the spacecraft’s L’LORRI imager, the asteroid appears to be larger than originally estimated, about 5 miles (8 km) long and 2 miles (3.5 km) wide at the widest point. In this first set of high-resolution images returned from the spacecraft, the full asteroid is not visible as the asteroid is larger than the imager’s field of view. It will take up to a week for the team to downlink the remainder of the encounter data from the spacecraft; this dataset will give a more complete picture of the asteroid’s overall shape.
Lucy is now on its way to the orbit of Jupiter, where it will get close-up views of five different Trojan asteroids in 2027, followed by a later visit to another group of Trojans in 2033.
SpaceX yesterday successfully launched three different payloads on its third “Bandwagon” launch, its Falcon 9 rocket lifting off from Cape Canaveral.
The first stage completed its third flight, landing back at Cape Canaveral. The fairings completed their second and fifteenth flights respectively.
The rocket’s primary payload was a commercial satellite for a South Korean company. Next was a commercial weather smallsat from the startup Tomorrow.
The third payload was from the European company Atmos, and was intended to test its deployable heat shield designed to protect payloads returning from orbit. According to the company, preliminary data says the deployment and return went as planned.
The leaders in the 2025 launch race:
46 SpaceX
20 China (with a launch scheduled for this morning)
5 Rocket Lab
5 Russia
SpaceX now leads the rest of the world in successful launches, 46 to 35.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on February 26, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).
The scientists describe these features as “dendritic relief features,” an apt description of the thousands of miles of river-like meandering ridges that orbital images have discovered in the past decade scattered across Mars, as noted in 2016:
The inverted channels are similar to those found elsewhere on Mars and Earth. They are made of sand and gravel deposited by a river and when the river becomes dry, the channels are left upstanding as the surrounding material erodes. On Earth, inverted channels often occur in dry, desert environments like Oman, Egypt, or Utah, where erosion rates are low – in most other environments, the channels are worn away before they can become inverted.
The most dramatic example of these Martian ridge rivers are the fernlike ridges in Antoniadi Crater. The ridges to the right however are almost as striking.

Due to its success in quickly redesigning the first stage of its Electron rocket into a hypersonic test vehicle dubbed HASTE, Rocket Lab has now won two very large hypersonic test program contracts from both the American Space Force as well as the United Kingdom.
Rocket Lab has been selected by the U.S. Air Force to participate within its Enterprise-Wide Agile Acquisition Contract (EWAAC), a $46 billion indefinite delivery-indefinite quantity (IDIQ) contract designed for the rapid acquisition of innovative technologies, engineering services, and technical solutions that develops the Air Force’s new capabilities. The program has a contracting period through to 2031 and is designed to be broad in scope, flexible in funding, and agile for maximum use to enable the Air Force to quickly procure services and technologies across various domains.
Further, Rocket Lab has also been selected by the United Kingdom’s Ministry of Defence (UK MOD) for its Hypersonic Technologies & Capability Development Framework (HTCDF), a ~$1.3 billion (£1 billion) framework to rapidly develop advanced hypersonic capabilities for the United Kingdom. As a newly-selected supplier to the HTCDF, Rocket Lab is now eligible to bid to provide services, technologies, and testing capabilities that support the UK’s development of sovereign hypersonic technology.
In both cases Rocket Lab will bid for test contracts using HASTE.
These deals indicate that Rocket Lab has essentially grabbed the business that Stratolaunch had been vying for with its giant Roc airplane and Talon test drop vehicles. Stratolaunch might get some contracts, but it appears the bulk of the work will instead go to Rocket Lab. It also appears that Stratolaunch has also been beaten to this business by the startup Varda, which has also won an Air Force contract for hypersonic testing using its orbital capsules during their return to Earth.
According to one government official, India’s space agency ISRO has now successfully completed a second autonomous docking in orbit using the target and chase spacecraft of its Spadex mission, launched in December 2024.
Between the undocking on March 13 and the second docking operation, Isro had carried out a “rolling” or “rotating” experiment — in late March. … At the time, Narayanan [ISRO chairman], while confirming the success of the operation, had said that more experiments were in store. … “…The satellites have a lot of propellant… I have only told [the teams] one thing, please do everything [on] simulation on ground [first]. Let us be very careful. Let us not make any mistakes as a wealth of data can be generated [through various experiments].”
The rolling experiment, which was likened to the Chandrayaan-3 “hop” experiment the space agency conducted on Moon in terms of learning it provides for future missions, helped Isro validate multiple softwares, ground station control and more.
This second docking further confirms the technology and the ability of ISRO’s engineers to perform it. Originally the plan had been to do only one docking. The two spacecraft were to then undock and go their separate ways, doing other orbital research. Narayanan changed that plan, since this technology is essential for India’s planned space station. The focus is now on multiple test dockings, in a variety of configurations, with more to come.
