Europe to spend $11 billion to build its own Starlink government constellation

9:26 am

The European Union has now finalized its $11 billion plan to build a government-owned 290 satellite constellation, dubbed IRIS2, to compete with Starlink and the many other private constellations already launching.

On 16 December, ESA, the European Commission, and the SpaceRIDE consortium, led by European satellite operators SES, Eutelsat, and Hispasat, signed a €10.55 billion, 12-year concession contract to develop the IRIS2 constellation.

…Under the contract terms, the EU will contribute €6 billion, the consortium €4 billion, and ESA €550 million toward the total value. In addition to the consortium’s three leads, the key partners include Thales Alenia Space, OHB, Airbus Defence and Space, Telespazio, Deutsche Telekom, Orange, Hisdesat, and Thales SIX.

As is usual for government projects, and especially for European ones, the time table for construction and launch is as slow as molasses. The first satellite won’t be launched until 2029, with the service not available until 2030. By that time there will be multiple such constellations in orbit, not just Starlink, offering services at rates far less than this system will likely offer.

This project is really nothing more than crony capitalism, creating a project to funnel government money to all these big European corporations. Fortunately, the project does demand they commit some of their own funds, which will at least act to keep them relatively honest.

Europe however would be better off leaving this to the companies entirely. If both SpaceX, OneWeb, and Amazon can build their internet constellations without government funds, why can’t these big European companies?

ESA continues to dither about building a heavy lift rocket

10:47 am

In what almost appears to be a clown show, the European Space Agency (ESA) has three times issued and then retracted and then reissued a request for proposals for studying possible designs to possibly build a heavy lift rocket to both replace Ariane-6 as well as compete with SpaceX’s Starship/Superheavy.

ESA published an initial call for its European 60T LEO Reusable Launch System Pathfinder Study initiative on 20 November. The call was, however, deleted later that day. On 3 December, a second version of the call was published and then removed, once again, on the same day. On 10 December, ESA published a third iteration of the call, with this one being the first to remain published overnight.

The second version put more emphasis on “time and cost efficiency.” The third version added details noting the limitations of Ariane-6 (its cost, limited payload capacity, and non-re-usability).

When ESA issued the second version, I noted its lack of urgency. “This is ‘call’ for a ‘study’ to ‘explore’ the ‘options’ for development. Hell will freeze over before ESA starts construction.” The new version doesn’t change this in the slightest. It only recognizes more fully the bad decisions that ESA made in 2015 when it approved the expendable design of Ariane-6, making it too expense then to compete with SpaceX’s Falcon 9.

Airbus cuts almost 500 jobs in Great Britain

9:30 am

As part of a larger planned belt-tightening that is expected to reducing staffing by more than 2,000, Airbus has now begun eliminating 477 jobs in its British operations.

The cuts are expected to hit the workforce in Stevenage and Portsmouth, where Airbus’s UK space operations are concentrated, while Newport in south Wales may also be impacted. The Stevenage site is also building Europe’s first Mars rover for a mission designed to search for signs of past or present life on the planet that’s due for launch in 2028.

Airbus said that only “overhead positions” – such as management support – will be hit, with nobody assigned to individual programmes or projects affected.

The company claims these cuts are due to SpaceX grabbing a large part of market share in the satellite business. It is also because Airbus is likely overstaffed, its operations shaped by the European Space Agency past requirement that it spread those operations to as many member nations as possible. These cuts in Great Britain are likely an attempt to reduce that spread.

PLD obtains a new loan, this time for $11.6 million

11:45 am

The Spanish rocket startup PLD yesterday announced it has obtained a new $11.6 million loan that it plans to use to build its launch facility at the French-owned French Guiana spaceport.

The loan was issued by the Spanish governmment finance agency COFIDES, which comes on top of an earlier $43.8 million Spanish government grant. In addition, the company has gotten a $2.4 million grant from the European Commission, as well as a $1.37 million grant from the European Space Agency.

The company has also obtained a loan of $34 million from banks in Spain.

All told, the company has raised about $164 million, more than $58 million came from government agencies, with another $34 million from loans.

For whatever reason, PLD has found favor with the various governments in Europe, fueling its work. None of the other European rocket startups from Germany or Great Britain have been as lucky.

ESA and JAXA sign agreement to increase cooperation and accelerate development of Ramses mission to Apophis

10:18 am

The new colonial movement: The European Space Agency (ESA) and Japan’s own space agency JAXA on November 20, 2024 signed a new cooperative agreement to increase their joint work on several missions, the most important of which is the proposed Ramses mission to the potentially dangerous asteroid Apophis during its 2029 close fly-by of Earth.

Two agencies agreed to accelerate to study potential cooperation for ESA’s Rapid Apophis Mission for Space Safety (RAMSES) which aims to explore the asteroid Apophis that will pass close to our planet on 13 April 2029, including but not limited to provision of thermal infrared imager and solar array wings as well as possible launch opportunities.

The two countries are already working together on two different planetary missions, the BepiColombo mission to Mercury and the Hera mission to the asteroid Dymorphos. Both are on their way to their targets. This new agreement solidifies the commitment of both to make sure Ramses is funded, built, and launched in the relatively short time left before that 2029 Earth fly-by. At the moment the ESA has still not officially funded it fully.

ESA awards four European rocket startups contact extensions worth €44.2 million total

9:19 am

Capitalism in space: The European Space Agency (ESA) this week awarded four European rocket startups — HyImpulse, Isar Aerospace, Rocket Factory Augsburg, and Orbex — new contact extensions worth €44.2 million total to continue the development of their commercial rockets.

According to ESA, the €44.2 million in funding awarded through the Boost! contract extensions is aimed at alleviating the pressure in the months before an inaugural flight when costs are high and the potential to generate revenue is limited.

…While the ESA press release did not disclose the specific amounts awarded to each company, announcements from the companies have revealed that Orbex will receive €5.6 million, Isar Aerospace €15 million, and both Rocket Factory Augsburg and HyImpulse €11.8 million each.

The first three companies are German-based, while Orbex is based in the United Kingdom. All four have received ESA grants under this program previously. None have yet actually attempted an orbital launch, but all four have been getting close, though all also face challenges. For example, Orbex, which had said it was ready to launch its Prime rocket in 2022, has been waiting for a launch license from Great Britain’s Civil Aviation Administration (CAA) for almost three years, to no avail. Rocket Factory meanwhile had hoped to launch its RFA-1 rocket this year, but could not after it was destroyed during a static fire dress rehearsal countdown in August.

Isar meanwhile has begun static fire tests of its Spectrum rocket at the Andoya spaceport in Norway. No launch date has been set. Hyimpulse in turn has flown a suborbital test flight from the Southern Launch spaceport on the south coast of Australia, but development of an orbital rocket seems farther behind its competitors.

This ESA contract award is also revealing in who did not get contracts. The large big space company ArianeGroup, which owns the Ariane-6 rocket, also has its own smallsat rocket startup, Maiaspace, that is attempting to compete with these other rocket startups, and had previously gotten ESA development contracts. That it got no contract extension under this program suggests ESA has decided it can manage without this aid, considering its owner is a well-financed big space contractor.

Old rockets clash with new rockets in Europe

9:35 am

Two stories today from Andrew Parsonson at his website Europeanspaceflight.com today illustrate the battle going on in Europe’s vast space bureaucracy over its future rocket development, and clearly tell us who is winning.

First Parsonson described a presentation put forth by Arianespace officials at an “Ariane-6 User’s Club” meeting two weeks ago, outlining the planned and proposed upgrades Arianespace intends for the Ariane-6 rocket over the next decade. All the upgrades are focused on increasing the rocket’s payloac capacity. None will make any of the rocket reusable in order to lower its high cost which makes it uncompetitive in the modern launch market.

What was significant about Parsonson’s report is that he also noted that many of these upgrades need to be approved by the European Space Agency (ESA), and its officials won’t make that decision until 2025 during a planned conference. Thus, this presentation by Arianespace was essentially a lobbying effort to convince ESA to approve these upgrades.

Parsonson’s second story then told us what ESA is approving, right now.

The European Space Agency has selected Rocket Factory Augsburg, The Exploration Company, ArianeGroup, and Isar Aerospace to develop reusable rocket technology.

On 9 October, ESA held its Future Space Transportation Award Ceremony in Paris. During the event, the agency announced the four awardees under two initiatives focused on the development of reusable rocket technology: the Technologies for High-thrust Reusable Space Transportation (THRUST!) project and the Boosters for European Space Transportation (BEST!) project.

Except for ArianeGroup, these are new startups. The German companies Rocket Factory and Isar are developing their own rockets, while the French company Exploration has so far focused on making cargo capsules to supply future space stations.

ArianeGroup meanwhile is the joint partnership between Airbus and Safran that built and owns the Ariane-6, and actually has more say on its future than Arianespace, which is merely a government agency that in the past (but no more) managed and controlled all of Europe’s rockets. ArianeGroup hasn’t abandoned Ariane-6 by no means, but clearly is shifting its interests in new directions.

Interestingly, the final decisions on some of these reusable projects will be made at that same 2025 conference.

Want to bet that ESA at that conference shifts its focus from upgrading the non-reusable Ariane-6 and instead goes whole hog for reusability? I expect that, especially because all recent political signs at ESA has indicated no interest in maintaining Arianespace any longer. For example, ESA has taken the Vega family of rockets away from Arianespace and given it back to Avio, the Italian company that manufactures it. ESA has also returned management of French Guiana from Arianespace to France’s space agency, which owns the site.

Designed as the commercial arm of ESA, it no longer has a function, now that Europe is shifting from the Soviet-model of its rocket operation run by the government (Arianespace) to a capitalism model where competing independent companies provide products and services to that government.

ESA awards OHB Italia a preliminary contract to build Ramses probe to Apophis

9:22 am

The European Space Agency (ESA) yesterday awarded the company OHB Italia a €63 million preliminary contract to begin work on mission dubbed Ramses that will launch in 2028 and rendezvous with the potentially dangerous asteroid Apophis when it flies past the Earth on April 13, 2029 at a distance of less than 20,000 miles.

The contract award is preliminary because the entire project still has to be approved by the ESA ministral council of nations, meeting in 2025. Because of the short development time, however, ESA’s management found funds from its existing budget to begin work.

To speed work, the project is also using as its design basis the Hera asteroid spacecraft, which was recently launched to study the binary asteroids Didymos-Dimorphos. That mission was also built remarkably fast for a European space project, going from contract to launch in just four years.

NASA has already re-tasked its OSIRIS-REx asteroid mission to head for Apophis, renaming it OSIRIS-APEX for reasons that baffle me. The mission had successfully delivered samples from the asteroid Bennu, but after completing that mission had sufficient fuel and was well placed to do this additional rendezvous as well.

First test images sent back by Hera asteroid probe

9:19 am

The Earth and Moon system as seen by Hera
Click for original image.

During its initial in-space commissioning to make sure everything is working properly after an October 7, 2024 launch, engineers have successfully taken the first test images by Hera asteroid probe, proving those instruments are operating as intended.

The picture to the right, cropped, reduced, and sharpened to post here, was taken by the spacecraft’s mid-infrared camera, and shows both the Earth (lower left) and the Moon (upper right) as seen from a little less than a million miles away. Once Hera reaches the binary asteroid system of Didymos and Dimorphos, this instrument will be used to measure the changes of temperature on the asteroids’ surface.

Images of Earth taken by two other instruments proved those instruments were functioning properly as well.

Hera is a European Space Agency (ESA) follow-up asteroid mission to see up close what changes were caused to Dimorphos by the impact of NASA’s Dart mission in 2022. It will rendezvous with the asteroid in late 2026 after flying past Mars and its moon Deimos in earlier that year. It will then spend about a half year flying in formation with the asteroids before a planned landing in late July 2027.

ESA awards D-Orbit €119.6 million contract to complete Europe’s first robotic service mission

9:25 am

The European Space Agency (ESA) today awarded the European orbital tug company D-Orbit a €119.6 million contract to fly Europe’s first robotic mission to extend the life of an already orbiting satellite.

Referred to as RISE, the mission will demonstrate the D-Orbit GEA satellite life extension vehicle’s ability to dock with a geostationary satellite, maneuver the satellite, and then release it. After this sequence is verified, ESA’s involvement in its operation will come to an end. The vehicle will then move into an operational phase with D-Orbit offering a life extension service to active geostationary satellite operators.

The mission is targeting a 2028 launch, though no specific target satellite as yet has been identified.

This project is very similar to the Mission Extension Vehicle (MEV) robotic missions of Northrop Grumman, which has been flown twice successfully. I guess ESA needed to see it work before it would consider doing its own mission. Moreover, ESA probably wanted to sign up a European company to do it, and until now no such company existed. D-Orbit has already completed fourteen orbital tug missions with seven more scheduled for 2025. This mission extension project however will be a significant leap forward in its capabilities, funded by ESA.

A new map of the magnetosphere of Mercury

12:11 pm

Map of Mercury's magnetosphere
Click for original.

Using data obtained during the June 2023 fly-by by the European-Japanese probe BepiColombo, scientists have now published a new detailed map of the magnetic field that surrounds Mercury.

That map is to the right. From the caption:

A textured sphere representing Mercury is shown with magnetic field lines compressed on the sunward side and streaming out into a tail on the nightside. The BepiColombo spacecraft’s trajectory is drawn passing through the magnetosphere from dawn to dusk, close to the planet’s surface. Various features in the magnetosphere are depicted and labelled with text. Following the order in which they were detected by the spacecraft, this includes the bow shock, magnetopause, low-latitude boundary layer, cold ion cloud, plasma sheet horn and ring current.

You can read the peer-reviewed paper here [pdf]. Note that this research does not include data obtained during BepiColumbo’s fourth fly-by of Mercury in September. Furthermore, the spacecraft will do two more fly-bys before arriving in orbit in 2026, where it will then separate into two separate orbiters in complementary orbits. Thus, this magnetic map of Mercury is merely a rough draft, and will be significantly refined by the end of the mission.

ESA awards Polish rocket startup €2.4 million contract

9:33 am

The European Space Agency (ESA) has awarded a Polish rocket startup, dubbed SpaceForest, €2.4 million to upgrade its suborbital Perun rocket that the company has test launched twice in last year.

Perun runs on modified paraffin, commonly used as candle wax, and so its propellant is non-toxic. The rocket can be launched on a mobile launch pad, allowing for easy deployment at launch facilities around Europe. Last year, SpaceForest launched two full-scale models of its Perun rocket that flew to 22 km and 13 km altitude from the coastal town of Ustka, Poland, on the Baltic Sea.

This company is now the second Polish rocket startup to have successfully tested its rocket. The Łukasiewicz Institute of Aviation has completed suborbital test flights of its ILR-33 Amber 2K rocket, and has a deal to fly its next test from Norway’s commercial Andoya spaceport.

Investigation into upper stage failure during Ariane-6’s first launch completed

8:38 am

The Ariane-6 rocket investigation team, including people from the European Space Agency (ESA), CNES (France’s space agency), ArianeGroup (which built and owns the rocket), and Arianespace (which presently manages the rocket), has identified the issue that caused the rocket’s upper stage failure during the rocket’s first launch in July.

In a 16 September update, the Task Force announced that the investigation had identified a single temperature measurement that “exceeded a predefined limit” as the root cause of the anomaly. The tripped limit caused the software to trigger a shutdown of the APU which ensured the rocket’s Vinci upper stage engine could not be restarted for the final burn.

In order to remedy this issue and ensure a similar shutdown does not occur in the future, the ignition preparation sequence, specifically the APU chill-down sequence, has been changed. The updated flight software is already being tested as teams prepare for the rocket’s first commercial flight which is set to take place before the end of the year.

Because of that incorrect temperature, the upper stage did not do its final burn, thereby stranding the stage and two demonstration return capsules in the wrong orbit. This prevented the test return of both capsules, as well as the test planned de-orbit of the stage over the ocean.

Arianespace successfully completes the last launch of Avio’s Vega rocket

9:29 pm

Tonight the last launch of the Vega rocket, built by the Italian company Avio and managed by Arianespace, successfully lifted off from French Guiana, placing a European Earth observation satellite into orbit.

The launch was delayed several years because of a failure during a previous launch that required a major redesign of an engine. Further delays took place when Avio literally lost the tanks for the rocket’s upper stage, and had to improvise a solution (which has never been explained fully).

The rocket will now be replaced by the Vega-C, which after several more launches will be entirely owned and managed by Avio, which will market it to satellite customers without any significant participation of the government middleman Arianespace.

This was only the second launch by Europe in 2024, so the leader board of the 2024 launch race does not change.

86 SpaceX
37 China
10 Rocket Lab
9 Russia

American private enterprise still leads the rest of the world combined in successful launches 101 to 56, while SpaceX by itself leads the entire world, including American companies 86 to 71.

Due to thruster problem, the Mercury orbiter BepiColombo will arrive at Mercury almost one year late

9:05 am

The joint ESA and JAXA Mercury mission BepiColombo will now reach its destination eleven months late because its ion electric thrusters are producing less thrust than expected.

The spacecraft is actually made up of two orbiters, one built by the European Space Agency (ESA) and the second built by Japan’s space agency JAXA. During launch and the journey to Mercury each is attached to a third spacecraft called the Mercury Transfer Module (MTM), which has the large electric ion thrusters used for making the mid-course corrections prior to and after each fly-by of the Earth (once), Venus (twice), and Mercury (six) before finally entering orbit around Mercury. It has already completed the Earth, Venus and three Mercury fly-bys.

In April 2024 engineers discovered that during a mid-course correction on April 26st the MTM’s thrusters failed to produce the desired thrust.

Engineers identified unexpected electric currents between MTM’s solar array and the unit responsible for extracting power and distributing it to the rest of the spacecraft. Onboard data imply that this is resulting in less power available for electric propulsion. ESA’s BepiColombo Mission Manager, Santa Martinez explains: “Following months of investigations, we have concluded that MTM’s electric thrusters will remain operating below the minimum thrust required for an insertion into orbit around Mercury in December 2025.”

In order not to lose the mission entirely, the science team has come up with a new trajectory that will have it fly past Mercury on its fourth fly-by on September 4, 2024 only 103 miles above the surface, 22 miles closer than originally planned. This will give it a larger slingshot speed boost to help make up for the under-powered thrusters. It will then make its planned fifth and sixth Mercury fly-bys in December ’24 and January ’25, the adjusted route having it arrive in Mercury orbit eleven months later than planned, in November 2026.

This new plan however means that the pictures taken this week during the Mercury fly-by will provide some nice high resolution details, far better than those produced by the earlier fly-bys.

Juice completes Earth fly-by, heads for Venus fly-by

9:07 am

Click for original image.

The European probe Juice yesterday successfully completed a close fly-by of the Earth and was thus successfully slingshoted on its way to its next fly-by, of Venus, on its way to Jupiter.

This fly-by was actually a double event. First Juice zipped past the Moon the day before, coming within 435 miles. Then, only one day later it passed the Earth at a distance of 4,230 miles, thus completing the first dual fly-by of the both the Earth and the Moon.

The flyby of the Moon increased Juice’s speed by 0.9 km/s relative to the Sun, guiding Juice towards Earth. The flyby of Earth reduced Juice’s speed by 4.8 km/s relative to the Sun, guiding Juice onto a new trajectory towards Venus. Overall, the lunar-Earth flyby deflected Juice by an angle of 100° compared to its pre-flyby path.

The inherently risky flyby required ultra-precise, real-time navigation, but is saving the mission around 100–150 kg of fuel. In the month before the flyby, spacecraft operators gave Juice slight nudges to put it on exactly the right approach trajectory. Then they tracked Juice 24/7 between 17–22 August.

The Venus fly-by will occur in August 2025, followed by additional Earth flys in September 2026 and January 2029. The spacecraft will finally arrive in Jupiter orbit in July 2031, where it is designed to study the large icy moons (Europa, Gandymede, and Calisto) of that gas giant.

Europe’s Juice probe to Jupiter yesterday successfully completed its close fly-by of the Moon, shifting its path as it prepares for a close fly-by of the Earth today.

The picture to the right, cropped, reduced, and sharpened to post here, was taken during yesterday’s flyby. At its closest approach Juice was only 435 miles above the lunar surface. It will pass the Earth today at a distance of 4,230 miles.

If the Earth fly-by today is successful, Juice will then do flybys of Venus in August 2025, Earth in September 2026, and Earth again in January 2029, arriving in Jupiter orbit in July 2031, where it is designed to study the large icy moons (Europa, Gandymede, and Calisto) of that gas giant.

Gaia space telescope identifies more than 350 asteroids with candidate moons

9:24 am

Using the Gaia space telescope, astronomers have identified 352 asteroids that the data suggests have smaller satellite asteroids in orbit around them.

In its data release 3, Gaia precisely pinpointed the positions and motions of 150 000+ asteroids — so precisely that scientists could dig deeper and hunt for asteroids displaying the characteristic ‘wobble’ caused by the tug of an orbiting companion (the same mechanism as displayed here for a binary star). Gaia also gathered data on asteroid chemistry, compiling the largest ever collection of asteroid ‘reflectance spectra’ (light curves that reveal an object’s colour and composition).

These results need to be confirmed by direct observation, as this method does involve some assumptions and uncertainties. If these numbers are confirmed however it will give planetary scientists a better census on the percentage of asteroids with moons, which in turn can be used to create better models of the formation of the solar system as well as the evolution of asteroids over time. At the moment scientists predict about one out of every six asteroids will have a moon. This data suggests that number might be high.

Arianespace finally schedules last Vega launch

9:04 am

After improvising an upper stage fix because the rocket’s Italian manufacturer, Avio, literally lost the stage’s tanks, Arianespace on July 31, 2024 finally scheduled the last Vega rocket launch, targeting a September 3, 2024 lift off from French Guiana.

The change to the upper stage was required after the company managed to lose two of its four propellant tanks. As the production line for the AVUM upper stage tanks had been shut down in anticipation of the rocket’s retirement, Avio was forced to find a way to instead utilize the larger propellant tanks from the Vega C AVUM+ upper stage. With this process now complete, the company has a clear path toward the rocket’s swan song.

This rocket has been replaced by the more powerful Vega-C. Control and ownership on future launches has also been shifted from Arianespace back to Avio as part of Europe’s transition from using a government-run launch monopoly (Ariancespace) to relying on multiple competitive and independent private companies.

Astroscale wins contract to deorbit OneWeb satellite

8:50 am

The orbital tug company Astroscale has won a $15 million contract from both the UK and European space agencies to launch a mission to rendezvous, grab and then deorbit a defunct OneWeb communications satellite.

The company, originally from Japan, has established operations in both the U.S. and Europe in order to win contracts from those regions, and had already signed contracts with OneWeb, several UK companies, the the European Space Agency (ESA), and the UK Space Agency for this project. This new contract apparently releases the money from both ESA and the UK.

The mission, dubbed ELSA-M, is will fly no later than April 2026, will be built by Astroscale’s UK division in Oxford, and is a follow-up of the ELSA-d mission that in 2021 demonstrated rendezvous and proximity operations but was unable to complete a docking using Astroscale’s magnetic capture system because of failed thrusters. I suspect the reason this new deal was finally approved is because of Astroscale’s more recent successes in another mission for Japan’s JAXA space agency, ADRAS-J, rendezvousing and flying in proximity to an old abandoned H2A rocket upper stage.

The new mission will attempt once again to prove the practicality of Astroscale’s magnetic capture system, which it is trying to convince all satellite companies to include on their satellites.

ESA’s Juice probe to Jupiter prepares for first Earth+Moon slingshot fly-by

The European Space Agency’s (ESA) first mission to Jupiter, dubbed Juice (Jupiter Icy Moons Explorer) is about to do the first ever back-to-back fly-bys of the Moon and then the Earth immediately afterward in order to slingshot it forward on its long journey to the gas giant.

The graphic to the right, cropped and reduced to post here, shows the plan. Juice will first fly past the Moon, shifting its path slightly, and then zip past the Earth one day later, its trajectory then under-going a much larger change.

The lunar-Earth flyby will see Juice pass just 700 km [435 miles] from the Moon’s surface at 23:16 CEST on 19 August and 6807 km [4230 miles] from Earth’s surface almost exactly 24 hours later at 23:57 CEST on 20 August.

Using the gravity of the Moon to slightly bend Juice’s trajectory first will improve the effectiveness of the much larger gravity assist at Earth. However, the dual flyby requires extraordinarily precise navigation and timing, as even minor deviations could send Juice in the wrong direction.

The engineering teams have already been doing simulations to make sure they get this complex maneuver right. If all goes right, the spacecraft will then do flybys of Venus in August 2025, Earth in September 2026, and Earth again in January 2029, arriving in Jupiter orbit in July 2031.

Europe’s Gaia space telescope in trouble

9:34 am

Launched in 2013 and now functioning more than six years after the completion of its primary mission to measure precisely the distances to over a billion stars, the European Space Agency’s Gaia space telescope has experienced several major technical issues this spring related to a micrometeorite hit and a failure of the electronics of one of its CCDs.

The micrometeorite hit occurred in April.

The impact created a little gap that allowed stray sunlight – around one billionth of the intensity of direct sunlight felt on Earth – to occasionally disrupt Gaia’s very sensitive sensors. Gaia’s engineers were in the middle of dealing with this issue when they were faced with another problem.

The spacecraft’s ‘billion-pixel camera’ relies on a series of 106 charge coupled devices (CCDs) – sensors that convert light into electrical signals. In May, the electronics controlling one of these CCDs failed – Gaia’s first CCD issue in more than 10 years in space. Each sensor has a different role, and the affected sensor was vital for Gaia’s ability to confirm the detection of stars. Without this sensor to validate its observations, Gaia began to register thousands of false detections.

The cause of the electronics failure remains unsolved, though it is believed related to the major solar storm that swept by at about the same time.

As a result of these issues, the telescope’s data stream will be significantly reduced. How long it will remain in operation remains unclear. At some point the cost will outweigh the amount of data obtained.

Europe targets 2031 for the first mission of its own lunar lander

10:48 am

The European Space Agency (ESA) has approved a target date of 2031 for the first mission of its own unmanned lunar lander, dubbed Argonaut, and launched on the most powerful version of the Ariane-6.

On 16 July, the agency published a call for Argonaut Mission 1 Phase A/B1 development aimed at demonstrating the technical and programmatic feasibility of the Argonaut mission concept. The call included a proposed launch date of 2031 for the first Argonaut mission to the Moon.

The Argonaut lunar lander will be launched aboard an Ariane 64 rocket. Once operational, ESA envisions it being used for a wide variety of applications, from cargo logistics to acting as an in-situ resource utilization plant. The agency has already completed pre-phase A studies for what it calls the European Charging Station for the Moon. This system would be launched aboard an Argonaut lunar lander and would essentially act as a gas station on the Moon that would be used to support crewed missions on the surface of the Moon.

As I’ve noted previously, ESA routinely sets a glacial pace on all its government-run projects. Do not expect this government lander to fly on this schedule. More likely by 2031 there will be many cheaper and available options from the private sector, and European companies wanting to put payloads down on the Moon will turn to those, especially because Argonaut is apparently being forced to use the expensive expendable Ariane-6 rocket. The cost for going on Argonaut is simply going to be too high.

ESA announces asteroid mission to Apophis

9:06 am

Apophis' path past the Earth in 2029
A cartoon showing Apophis’s path in 2029

The European Space Agency (ESA) today announced that is beginning work on an asteroid mission, dubbed Ramses, to the potentially dangerous asteroid Apophis when it makes its next close-fly of the Earth in 2029.

Ramses needs to launch in April 2028 to allow for an arrival at Apophis in February 2029, two months before the close approach. In order to meet this deadline, ESA requested permission to begin preparatory work on the mission as soon as possible using existing resources. This permission has been granted by the Space Safety programme board. The decision whether to commit to the mission in full will take place at ESA’s Ministerial Council Meeting in November 2025.

Using a suite of scientific instruments, the spacecraft will conduct a thorough before-and-after survey of the asteroid’s shape, surface, orbit, rotation and orientation. By analysing how Apophis changes during the flyby, scientists will learn a lot about the response of an asteroid to external forces as well as asteroid composition, interior structure, cohesion, mass, density, and porosity.

Based on the track record of European space projects, which appear to always proceed at a glacial pace with late problems that cause the missions to miss their launch window (with the launch of the Franklin Mars rover as the poster child), the project is getting started far too late to meet its launch date of April 2028. We shall see if Europe surprises us this time and gets the project off the ground as planned.

Right now the only confirmed mission to Apophis is OSIRIS-APEX, which was redirected to the asteroid after it delivered its samples from Bennu to Earth. Many others have been proposed, including a commercial mission, but none appear to be confirmed or under construction.

Watch the first launch of Europe’s Ariane-6 rocket

9:14 am

Europe’s Ariane-6 rocket, first proposed in 2014 and about four years behind schedule, will finally make its first launch at 2 pm (Eastern) today.

I have embedded the live stream below.

The rocket was conceived by the European Space Agency (ESA) as an attempt to compete with SpaceX’s Falcon 9 rocket. It failed to do this from day one, since the rocket was from day one designed to be expendable. By the 2020s it became clear to European satellite companies and government agencies that its launch cost would be far higher that the Falcon 9, and these companies and agencies have therefore resisted signing launch contracts with ArianeGroup. In fact, if Amazon had not decided in ’22 to give the Ariane-6 a contract for 18 launches to put up its Kuiper satellites, the rocket would have almost no launches in its manifest.

This situation was made even more starkly evident at the end of June, when the European governent weather company Eumetsat cancelled its Ariane-6 contract and switched to the Falcon 9.

Though the unelected bureaucrats and apparatchiks in the European Union are trying to require the use of Ariane-6, ESA and Europe’s rocket future resides in the independent rocket startups (Rocket Factory Augsburg, Isar Aerospace, Hyimpulse, PLD). Because they are in competition with each other as well as SpaceX, and are not saddled with heavy government interference, they can focus on innovating to lower cost. Expect them to quickly begin launching in the next three years, with reusability soon to follow.

ESA approves taking the Vega-C rocket away from Arianespace

9:12 am

The council that runs the European Space Agency (ESA) today approved a resolution that shifted ownership of the Vega-C rocket away from government-run Arianespace and giving it back to its builder, the Italian aerospace company Avio.

Arianespace and Avio have agreed that Arianespace will remain the launch service provider and operator for Vega and Vega-C launch services until Vega flight 29 (VV29), scheduled for the fourth quarter of 2025. For Vega-C launches following VV29, the customers who have already contracted with Arianespace will be offered the possibility to transfer their contracts to Avio as the new launch service provider and sole operator of Vega.

Arianespace will primarily focus with ArianeGroup on the Ariane 6 exploitation to best meet the customer needs.

The council also agreed with France’s plan to allow independent commercial rocket startups to launch from French Guiana. Control of that spaceport has also been taken from Arianespace and returned to its owner, the French space agency CNES.

Essentially, this decision ties Arianespace’s future to Ariane-6, which is likely to disappear once its present manifest of launches, mostly for Amazon’s Kuiper constellation, gets launched.

Arianespace calls for Europe to require all European space payloads use European rockets

9:57 am

Arianespace, whose many-decade-long European launch monopoly is presently threatened by a wave of new rocket startups and an effort by European governments to created a competitive launch industry of many companies, has now urged Europe to require that all European space payloads use European rockets.

Arianespace head of public affairs Charlotte Lang has advocated for legislation that would require European missions to be launched aboard European rockets. Lang made the comments during the “Ensuring Long Term Autonomous Access to Space for Europe” panel on the first day of The European Space Forum conference. “The EU should enforce the principle of European launcher preference,” said Lang.

In a follow-up statement, Arianespace reiterated “the need for the EU to legislate that European missions are launched from European territory using launchers and technology manufactured in Europe by European providers.” The company identified the European Union’s planned IRIS² constellation as the “perfect opportunity to advance this initiative.”

Arianespace is like Blue Origin. It can’t get its rockets built and flying at a competitive price, so instead it advocates lawfare to limit competition in order to give it a favored position when it bids on future launch contracts.

In the case of Europe, I think this Arianespace effort will generally fall on deaf ears. The trend among numerous European governments (Germany, France, Italy) is to encourage new rocket companies to compete with Arianespace, in order to create options. These governments will of course wish to favor these new European rocket companies with any contract awards, but they will also not want to tie their hands with the kind of legislation Arianespace proposes. They all discovered in the past two years what could happen if they do that, when Arianespace failed to get Ariane-6 launched on time, and Europe ended up with no launch capabilities. During that time period they still had the option to use other non-European options (such as SpaceX). Having that flexibility in the future makes great sense.

Slovenia becomes 23rd member nation of the European Space Agency

9:05 am

Formerly part of Yugoslavia and largely aligned with the communist bloc during the Cold War, Slovenia has now signed on to become the 23rd member nation of the European Space Agency (ESA).

Slovenia has been working with ESA since 2008, when it signed a first Cooperation Agreement, followed by a European Cooperation Agreement. This cooperation was strengthened with its accession to associate membership in 2016, which it upgraded in 2020 with a new Agreement for an enhanced Association. This included a provision that after its expiration in 2025, Slovenia can apply for ESA membership.

Slovenia’s membership still needs to be ratified, but that is expected.

Increasingly Putin’s invasion of the Ukraine has proven to be incredibly stupid. It has not only trapped Russia in a quagmire that it can’t easily escape, with victory nowhere in sight, it has caused all of its other neighbors to look west, away from Russia, out of fear of getting invaded themselves. Slovenia is just the most recent example.

ESA signs deal with Vast to use its Haven-1 space station

2:51 pm

The European Space Agency (ESA) and the commercial space station startup Vast today signed an agreement that sets the initial terms for ESA to use Vast’s first space station, Haven-1, as well as any space stations to follow.

The agreement outlines the parties’ intention to foster human spaceflight, science, technology and commercialisation development and explore collaboration in low Earth orbit destinations other than the International Space Station. The collaboration will initially focus on exploring opportunities for access to space for Europe through the Vast Space Stations. These could include:

  • Access to the Vast Space Stations for ESA and its Member States, for astronaut missions and research activities as well as commercial business development.
  • Supporting European industry to supply subsystems and equipment for future Vast Space Stations.
  • Vast making use of future qualified European LEO cargo and/or crew transportation services, at market rates and commercially viable terms and conditions, also as a means for offsetting future ESA Astronaut Missions.
  • Vast and ESA jointly supporting European industry in getting certified for docking to future Vast Space Stations.

This deal is actually a very big deal, as Vast’s Haven-1 space station is the only one under construction that does not have a deal with NASA. It is being financed privately and will at first simply be a one module habitat set to launch as early as August 2025 on a Falcon 9 rocket, with the first 30-day 4-person manned mission to follow almost immediately on a Dragon capsule. Vast’s work is closely linked with SpaceX, as its station also has a deal to use Starlink for communications.

The plan is to add more modules in the coming years to build up to a full station.

This deal not only indicates that this independent station is going to give the NASA-supported stations some real competition, it indicates that Europe is committed to doing the same. Now that Europe has abandoned the government-owned and international cooperation model it has used for decades with decidedly mixed results and switched to the capitalism model, where it is merely a customer buying things from a competing private sector, it is doing so full speed ahead, without any hesitation.

The independence of this station also frees it and its customers from the heavy rules that NASA routinely imposes on anyone who deals with it. This aspect gives Vast a competitive advantage that many will clearly wish to take advantage of.

This deal is therefore a challenge that better be recognized by NASA and the other commercial stations. If they don’t react properly they could find themselves left in the dust completely.
