Europe’s deep space communications network to support India’s next two missions beyond Earth orbit

8:52 am

The new colonial movement: Based upon a 2021 agreement, the European Space Agency (ESA) today outlined how its deep space communications network of antennas will support India’s next two missions beyond Earth orbit.

ESA’s global deep-space communication antennas will provide essential support to both missions every step of the way, tracking the spacecraft, pinpointing their locations at crucial stages, transmitting commands and receiving ‘telemetry’ and valuable science data.

In June 2021, ESA and the Indian Space Research Organisation (ISRO) signed an agreement to provide technical support to each other, including tracking and communication services to upcoming Indian space missions via ESA’s ground stations.

The first missions to benefit from this new support agreement will enable India look to the Sun and the Moon with the Aditya-L1 solar observatory and Chandrayaan-3 lunar lander and rover, both due to launch in 2022 from the Satish Dhawan Space Centre in Sriharikota Range (SDSC SHAR), India.

Though scheduled for launch this year, ISRO (India’s space agency) has not yet announced firm launch dates for either.

This arrangement signals an effort by India and Europe to remain independent of the American Artemis program, which is NASA’s central program for manned missions beyond Earth orbit. To partner with NASA for such missions the Trump administration had demanded nations sign the Artemis Accords, though that requirement might have been eased by the Biden administration for deep space communications.

Regardless, this agreement gives both India and ESA flexibility for remaining outside the accords, at least for now. Neither India nor most of the partners in the ESA have signed, with France and Germany the most notable European nations remaining outside the accords.

Solar Orbiter takes closest image of Sun so far

10:18 am

Solar Orbiter's closest image of the Sun, so far
Click for full interactive image, where you can zoom in, a lot.

Cool image time! The European Space Agency (ESA) yesterday released several new images from its Solar Orbiter probe, taken when the spacecraft made its most recent closest approach of the Sun.

One of the images, taken by the Extreme Ultraviolet Imager (EUI) is the highest resolution image of the Sun’s full disc and outer atmosphere, the corona, ever taken.

Another image, taken by the Spectral Imaging of the Coronal Environment (SPICE) instrument represents the first full Sun image of its kind in 50 years, and by far the best one, taken at the Lyman-beta wavelength of ultraviolet light that is emitted by hydrogen gas.

The images were taken when Solar Orbiter was at a distance of roughly 75 million kilometres, half way between our world and its parent star. The high-resolution telescope of EUI takes pictures of such high spatial resolution that, at that close distance, a mosaic of 25 individual images is needed to cover the entire Sun. Taken one after the other, the full image was captured over a period of more than four hours because each tile takes about 10 minutes, including the time for the spacecraft to point from one segment to the next.

The photo to the right, reduced to post here, is the EUI photo.

Solar Orbiter has been in its science orbit since November, though that orbit over time will slowly be adjusted to swing the spacecraft into a higher inclination so that it can make the first close-up observations of the Sun’s polar regions. It is also working in tandem with the Parker Solar Probe, which observes the Sun from even closer distances using different instruments.

ESA: ExoMars launch in ’22 “very unlikely” due to Russian invasion of the Ukraine

9:05 am

In a statement yesterday condemning Russia’s invasion of the Ukraine and responding to the Russians’ decision to suspend cooperation with Arianespace in French Guiana, the European Space Agency (ESA) also admitted, almost as an aside, that the ExoMars launch in ’22 to Mars is now “very unlikely.”

That mission is a partnership with Russia, where the Russians provide the rocket and the lander that will put Europe’s Franklin rover on the surface.

For the scientists running ExoMars, this delay only adds to their frustration, as the mission has already been delayed several times, most recently from a ’20 launch because the lander parachutes — being built by ESA — were not ready.

ESA dithers, forming committee to study concept of building its own manned capsule

9:37 am

My heart be still! The European Space Agency (ESA) has decided to create a committee to study the concept of building a European manned capsule so that it will no longer be dependent on either the U.S. or Russia to get its astronauts into space.

Aschbacher said a draft mandate for the new advisory group will be presented to ESA members at a March meeting of the ESA Council, with the goal for the group to start working immediately thereafter. The committee will prepare an interim report in time for the ministerial meeting in November, with a final report by next spring.

“It is clear that this group has to be independent and comprising mostly non-space experts,” he said, “because we really would like to look at various aspects of society from an economic point of view, a historical point of view, a geopolitical point of view.” That means including people such as artists and philosophers in the group to look at various aspects of exploration beyond science and technology. [emphasis mine]

The highlighted words illustrate the empty PR nature of this committee. It will not result in any European manned spacecraft at all. Instead, it will spend more than a year talking a lot about the wonders of space, and then produce a report repeating how wonderful space is and how Europe must be there.

The result? ESA will have wasted a year and not gotten itself one iota closer to having its own manned spacecraft.

If this hollow effort was the exception to the rule for Europe, there might be hope some political pressure could get the committee reformed and actually include engineers to develop a real design. That hope is in vain, however, because this is how Europe and ESA does everything. By the time ESA produces the first designs of this capsule, probably five to six years hence, it will be so out-of-date that building it would be a joke.

In a larger sense, this absurd committee and the top management at ESA and in the European Union that proposed it illustrate the overall bankruptcy of modern civilization’s entire management class. The people running governments worldwide are generally all do-nothing idiots, who talk a lot, waste a lot of money for their own aggrandizement, impose taxes and regulations on everyone else that makes the lives of ordinary people a misery, and fail in almost every project they undertake. We need only look at their panicked, dishonest, and failed global response to the Wuhan flu in the past two years for a prime example.

The official intellectual class that is running our governments worldwide are bankrupt. They need to be fired.

ESA selects Ariane-6’s first payloads

9:05 am

The European Space Agency (ESA), ArianeGroup, and Arianespace today announced the payloads that will fly on the first launch of its new Ariane-6 rocket.

The payloads are a variety of cubesats and science experiments, none heavier than 175 pounds with a total payload weight less than one ton. These secondary payloads will either be deployed from or kept attached to a dummy mass that will simulate a large primary satellite payload.

The press release makes no mention of a launch date, as has been the pattern in the last few Ariane-6 press releases. The last release to mention a launch date was in October 2020, which then predicted a launch in the second quarter of ’22. That this date is no longer being mentioned suggests the date has been pushed back, though for how long remains a mystery.

Lockheed Martin wins NASA contract to build Mars rocket

9:11 am

Capitalism in space: NASA yesterday awarded Lockheed Martin a $194 million contract to build the Mars rocket that will lift Perseverance’s samples into orbit for return to Earth.

Set to become the first rocket fired off another planet, the MAV [Mars Ascent Vehicle] is a crucial part of a campaign to retrieve samples collected by NASA’s Perseverance rover and deliver them to Earth for advanced study. NASA’s Sample Retrieval Lander, another important part of the campaign, would carry the MAV to Mars’ surface, landing near or in Jezero Crater to gather the samples cached by Perseverance. The samples would be returned to the lander, which would serve as the launch platform for the MAV. With the sample container secured, the MAV would then launch.

Once it reaches Mars orbit, the container would be captured by an ESA (European Space Agency) Earth Return Orbiter spacecraft outfitted with NASA’s Capture, Containment, and Return System payload. The spacecraft would bring the samples to Earth safely and securely in the early- to mid-2030s.

According to this project’s webpage, the European Space Agency (ESA) is building that they call a “fetch rover” which will be deployed from the rover to get the samples and bring them back to the MAV.

There are a lot of uncertainties in this scenario. It has been decades since Lockheed Martin built rockets. ESA has not yet built an operational Mars rover. It is also unclear who will build NASA’s lander and capture/return payload. Thus, do not expect this mission to launch “as early as ’26,” as the press release says. I predict it will launch at least five, maybe ever ten years, later.

Webb telescope reaches launchpad on Ariane 5 + how to watch launch

9:14 am

The James Webb Space Telescope, stacked on top of Arianespace’s Ariane 5 rocket, has finally reached its launchpad in French Guiana after twenty years of development costing 20 times its original budget.

The launch itself is now scheduled for December 25, 2021 at 7:20 am (Eastern). It will be live streamed by both NASA (in English) and Arianespace (with options in English, French, or Spanish).

I have embedded below NASA’s feed. As always, expect NASA to pump you with lots of propaganda during its live stream.

When all is said and done, Webb has the chance to show us things about the universe we’ve never seen before. Optimized for deep space cosmology, it will provide us a window into the earliest moments of the universe’s existence. And is infrared capabilities will allow it to peer into many nearer places obscured by dust with a resolution unmatched by previous telescopes.

Keep your fingers crossed all goes as planned.

ESA delays Webb launch one day due to weather

8:41 am

The European Space Agency (ESA) announced late yesterday that, due to “adverse weather conditions” in French Guiana, it has delayed the launch of the James Webb Space Telescope on an Ariane 5 rocket one day to December 25th.

The announcement also stated that the final launch readiness review also approved the launch, though no update has yet been issued on the ground control communications problem that had caused a two day delay last week.

Meanwhile, this story and its headline encapsulates the terror I think many astronomers presently feel about this telescope:

Why Astronomers Are “Crying and Throwing Up Everywhere” Over the Upcoming Telescope Launch

The sense is one of helpless panic among astronomers who want to use Webb. They know it will do really cutting edge science, but they also know that many things can go wrong, and the history of the telescope (ten years late and 20x overbudget) will likely make replacing it impossible.

And many things can go wrong. Below is NASA’s video showing the telescope’s complex unfolding, step-by-step, after launch.

Scientists discover underground reservoir of hydrogen, likely ice, near Martian equator

8:58 am

Detection of underground hydrogen in Valles Marineris
Click for full image.

In what could be a very significant discovery, scientists using Europe’s Trace Gas Orbiter (TGO) have discovered a surprisingly large underground reservoir of hydrogen, likely ice, near Martian equator and inside the solar system’s largest known canyon, Valles Marineris.

The map to the right, reduced to post here, provides all the important data. From its caption:

The coloured scale at the bottom of the frame shows the amount of ‘water-equivalent hydrogen’ (WEH) by weight (wt%). As reflected on these scales, the purple contours in the centre of this figure show the most water-rich region. In the area marked with a ‘C’, up to 40% of the near-surface material appears to be composed of water (by weight). The area marked ‘C’ is about the size of the Netherlands and overlaps with the deep valleys of Candor Chaos, part of the canyon system considered promising in our hunt for water on Mars.

What the caption does not note is the latitude of this hydrogen, about 3 to 10 degrees south latitude. Assuming the hydrogen represents underground ice, this would be the first detection on Mars below 30 degrees latitude, and the very first in the equatorial regions. Data from orbit has suggested that Mars has a lot of water ice, found near the surface more and more as you move into higher latitudes above 30 degrees and making Mars much like Antarctica. Almost no ice however had until now been detected below 30 degrees latitude. As the European Space Agency’s press release noted,

Arianespace launches two Galileo GPS-type satellites

8:14 pm

Capitalism in space: Using a Russian Soyuz-2 rocket, Arianespace successfully launched two Galileo GPS-type satellites from its spaceport in French Guiana tonight.

The leaders in the 2021 launch race:

45 China
27 SpaceX
20 Russia
6 Europe (Arianespace)

China still leads the U.S. 45 to 42 in the national rankings. This launch tonight was 116th successful launch in 2021, which is the most launches completed in a year since 1988. Based on the number of planned launched over the next three weeks, there is an outside chance that the global total will top 127, making this the second most active year ever in the history of space. Even if the numbers end up in the mid-120s, 2021 will be among the top eight years ever.

And I expect next year to easily top this year.

Mars Express successfully relays data from Zhurong to Earth

10:21 am

The European Space Agency’s Mars Express orbiter has successfully been used to relay data from China’s Zhurong Mars rover to Earth and then to China.

In November, ESA’s Mars Express and CNSA’s Zhurong teams carried out a series of experimental communication tests in which Mars Express used this ‘in the blind’ mode to listen for signals sent to it by the Zhurong Rover.

The experiments culminated in a successful test on 20 November. “Mars Express successfully received the signals sent by the rover, and our colleagues in the Zhurong team confirmed that all the data arrived on Earth in very good quality.” says ESA’s Gerhard Billig.

Apparently, normal communications would first involve “handshake” communications between the two, but that requires communications frequencies Zhurong does not use. Mars Express instead had to grab the data on the blind. The test was a success, which means the ESA will likely act as another communications relay for Zhurong, in addition to China’s Tianwen-1 orbiter, as the rover’s mission on Mars continues.

Engineers: Webb undamaged by “incident”, ready for December 22nd launch

9:46 am

Arianespace engineers have confirmed after testing that the James Webb Space Telescope was undamaged by “incident” that occurred during stacking, and have okayed the resumption of the telescope’s preparation for launch.

On Wednesday, Nov. 24, engineering teams completed these tests, and a NASA-led anomaly review board concluded no observatory components were damaged in the incident. A “consent to fuel” review was held, and NASA gave approval to begin fueling the observatory. Fueling operations will begin Thursday, Nov. 25, and will take about 10 days.

The launch is now set for December 22nd.

Europe’s Solar Orbiter to make last flyby of Earth

8:51 am

Solar Orbiter, the European Space Agency’s (ESA) probe to work in tandem with NASA Parker Solar Probe in studying the inner regions surrounding the Sun, will make last flyby of Earth on November 27, 2021, thus putting it into its planned science orbit.

While the press release gives a good overview of the mission, it focuses on the risk during that fly-by of the spacecraft hitting something during its close approach.

Solar Orbiter’s Earth flyby takes place on 27 November. At 04:30 GMT (05:30 CET) on that day, the spacecraft will be at its closest approach, just 460 km above North Africa and the Canary Islands. This is almost as close as the orbit of the International Space Station.

The manoeuvre is essential to decrease the energy of the spacecraft and line it up for its next close pass of the Sun but it comes with a risk. The spacecraft must pass through two orbital regions, each of which is populated with space debris.

The first is the geostationary ring of satellites at 36 000 km, and the second is the collection of low Earth orbits at around 400 km. As a result, there is a small risk of a collision. Solar Orbiter’s operations team are monitoring the situation very closely and will alter the spacecraft’s trajectory if it appears to be in any danger.

While there is a risk, it seems to me that ESA is taking advantage of the recent news outburst in connection with the Russian anti-sat test and the space junk it created to sell this mission. The risk of impact during this fly-by is very low, especially in the geostationary ring.

Italy switches from Arianespace to SpaceX for launch contract

9:05 am

Capitalism in space: Because of the two recent launch failures of Arianespace’s Vega rocket (built mostly in Italy), the Italian space agency (ASI) has decided to take the launch of an Earth observation satellite from Arianespace and award the launch contract instead to SpaceX.

The article at the link describes in detail the history and politics that make this decision significant. Essentially, because Arianespace in the past decade has failed to meet the challenge of SpaceX, so that its launches continue to be more expensive, this government-subsidized business has tried to force nations in the European Space Agency (ESA) to use Arianespace rockets via political agreements.

With this decision Italy is defying that pressure, which in turn is going to increase the pressure on Arianespace to finally step up its game, or die from lack of business. For example, when the ESA agreed to have Arianespace build its next generation rocket, the Ariane 6, it failed to require it to be reuseable. The Ariane 6 rocket was therefore designed as an expendable rocket, which meant that right from the start it could not compete with SpaceX’s Falcon 9. It has therefore failed to win launch contracts.

Expect the Ariane 6 to continue to fade as the years pass, simply because the bureaucrats in ESA and Arianespace refused to take their competition seriously.

Arianespace successfully completes first Ariane 5 launch in almost a year

11:23 pm

Arianespace today successfully completed its first Ariane 5 launch since August 2020, placing in orbit two commercial communications satellites.

The long gap in launches occurred because of a vibration issue discovered during that August 2020 launch durng the release of the rocket’s two fairing halves.

Engineers introduced modifications to the Ariane 5’s payload fairing, or nose cone, to reduce vibrations imparted on the satellites during separation of the shroud, which protects payloads during the first few minutes of flight through the atmosphere. Ground teams will analyze data from the rocket to make sure the changes reduced the vibrations.

Another launch is scheduled for September, followed next by the launch of the James Webb Space Telescope in either November or December. The results from today’s launch as well as the one in September will determine if the Webb launch will go forward on time.

These issues with Ariane 5, delays imposed by the company in fear of the Wuhan flu, and other launch problems with Arianespace’s Vega rocket, has meant that this is only its second launch in 2021, a pace that is below its pace for most of the last decade. Whether the company can recover and pick up the pace before the end of the year will depend on what they learn during today’s launch.

With only two launches total, Europe’s Arianespace remains off the leader board in the 2021 launch race:

24 China
20 SpaceX
12 Russia
3 Northrop Grumman
3 Rocket Lab

The U.S. lead over China in the national rankings remains 30 to 24.

Ariane 6 inaugural launch date appears to be delayed again

9:46 am

It appears that officials at the European Space Agency (ESA) have begun preparing the public for a further delay in the first launch of its new Ariane 6 rocket, from the second quarter of 2022, as announced in October 2020, to the third quarter of 2022, at the earliest.

Josef Aschbacher, director general of the European Space Agency, at the Paris Air Forum [described the creation of] “a small group” … to make an independent assessment of the schedule for the final development phase of the Ariane 6 rocket. The goal of this task force will be to ensure that Europe does everything it needs to do launch on time.

…In referring to an “on time” launch, Aschbacher said he meant next year, before the European Space Agency’s Ministerial Council meeting that is typically held in October or November. This is a high-level meeting where representatives from each member nation of the space agency gather to set policy. The European Space Agency’s budget is provided, in varying amounts, by member nations. “This is a must,” Aschbacher said of launching before the 2022 meeting, “because we need good news, and good success, for our politicians to see that Europe performs, that Europe delivers, and therefore it is worth investing in space in the ministerial conference.”

It appears from these statements that the development of Ariane 6 is now faced with delays that might make a launch by the third quarter in ’22 difficult, and this new independent committee is being put together to try to forestall that possibility. What makes this even more significant for Ariane 6 is that it continues to have trouble winning contracts from the nations within ESA, as it remains far more expensive that SpaceX’s Falcon 9. If that first launch is delayed past that important fall ’22 high-level meeting, those politicians at that meeting might decide to consider serious new alternatives to it, or even more drastically decide to replace it entirely.

Europe to fly mission to Venus to study its volcanoes

9:32 am

The European Space Agency yesterday announced that it will fly an orbiter to Venus in 2031, dubbed EnVision, to study the estimated million volcanoes on the surface of that hellish planet.

EnVision will use an infrared spectrometer to seek out hot spots on the surface that could indicate active volcanoes. It will use radar to map the surface, looking for signs of lava flows. Ultraviolet and high-resolution infrared spectrometers will then look for water vapor and sulfur dioxide emissions, to see whether smoldering volcanoes are driving cloud chemistry today.

This data will help determine exactly geologically active Venus’s volcanoes are. Several studies in the past decade using archival data (see here, here, and here) have suggested as many as 37 of those volcanoes are active, but this data remains uncertain.

German smallsat rocket startup wins launch contract

8:42 am

Capitalism in space: The German smallsat rocket startup company Isar Aerospace has won its first launch contract, to place an Airbus Earth observation satellite using its new Spectrum rocket.

Isar is one of three new German rocket companies competing for the smallsat market that all hope to launch for the first time next year.

Along with Rocket Factory Augsburg and HyImpulse Technologies, the three startups are competing as part of the German Space Agency DLR’s microlauncher competition.

The competition, which is being run in conjunction with ESA [European Space Agency], will award one of the three startups with 11 million euros ($13 million) in funding later this year. The funding is to be used to support a qualification flight that will carry a payload for a university or research institution for free. A second prize of 11 million euros in funding will then be awarded in 2022 as the final stage of the competition.

In evaluating the three startups, the DLR panel of judges will examine the technical aspects and commercial feasibility of each launcher. As a result, each startup’s success in securing funding and signing launch contracts will play a role in their chance of winning the competition.

Rocket Factory has also won a launch contract, with that commercial launch set for 2024.

Note how ESA is shifting its approach. Previously it focused its commercial effort entirely within the government-controlled Arianespace company. Now it is awarding competitive contracts to independent private companies. It appears that the ESA, like NASA, is adopting the recommendations put forth in my policy paper Capitalism in Space. It no longer wants to be the company but is instead acting as a customer looking for a product to buy.

Hopefully more than one of these three German companies will succeed, so that the competition will increase. That in turn will force prices down while encouraging greater innovation.

Europe and China discussing future space cooperation

8:49 am

The new colonial movement: The heads of the space agencies of both Europe and China held a virtual face-to-face discussion on April 1st, discussing their space operations as well as the possibility of future cooperation.

Zhang Kejian, administrator of the CNSA, and new ESA Director General Josef Aschbacher, who entered the post March 1, discussed a range of topics according to a short CNSA press release (Chinese). The parties outlined upcoming activities, with China recently approving a 14th Five-year plan for 2021-2025, and discussed lunar and deep space exploration, Earth observation, and cooperation in ground station.

Josef Aschbacher tweeted after the meeting that he had congratulated Zhang on the Chang’e-5 lunar sample return mission, which in December 2020 delivered to Earth 1.73 kilograms of lunar samples from Oceanus Procellarum on the moon’s near side.

…Karl Bergquist, ESA’s international relations administrator, told SpaceNews that ESA and CNSA went over ongoing activities including telemetry, tracking, and control support activities for the Chinese exploration program.

Apparently Zhang raised the issue of Europe contributing to China’s proposed lunar base. Aschbacher made no commitments, though he later stated that while there is “no ESA stance on this topic”, he anticipates future discussions on the topic.

Some of this is similar to the recent discussions between NASA and China, focused on exchanging telemetry of various orbiters to avoid the possibility of collisions or interference with their operation. I would not be surprised however if Europe expands this conversation and joins China in its space plans. The U.S. is shifting from a government-run space program — which both China and Europe favor — to a commercial model mostly run by private enterprise. Under that model there will be less opportunity for European participation in American space projects.

ESA awards UK’s Orbex 7.45 million euros to fund rocket development

10:14 am

Capitalism in space: The European Space Agency (ESA) has awarded the new United Kingdom smallsat launch company Orbex 7.45 million euros to help fund the development of its Prime rocket.

This will supplement the 4.7 million euros that Orbex has raised from private capital.

The funds from the award will go towards the completion of spaceflight systems in preparation for the first launches of Orbex’s 19-metre ‘microlauncher’ rocket, Prime. €11.25 million of the total funding will be assigned to work undertaken in the UK, in particular the lightweight avionics designed in-house by Orbex in Forres, and the guidance, navigation and control (GNC) software subsystem being designed by Elecnor Deimos, a strategic investor and partner of Orbex. The remaining €900,000 of the total funding package will support the development of the GNC for the orbital phase being developed by Elecnor Deimos for Orbex in Portugal.

If all goes right, Prime will make its first launch from Sutherland, Scotland, in ’22.

The contract award signals the shift at ESA that resembles what happened at NASA in the past decade, moving from designing and building its rockets and spacecraft to buying the product from private companies. While ESA might be providing a large bulk of the capital to develop Prime, it appears ESA is not involving itself heavily in the development itself, leaving that instead to the company.

ESA contracts Airbus to build three more Orion service modules

11:38 am

The European Space Agency (ESA) late last week announced that it has awarded Airbus a contract to build three more service modules for NASA’s Orion capsule.

This new contract supplements the existing contract that already has Airbus building three service modules. With six service modules in the pipeline, the ESA is signaling that it is very confident the Artemis program will continue.

The key question remains: Will it continue with SLS as the rocket of choice? Right now there simply aren’t the funds to build six SLS rockets. Congress has only funded two. Moreover, the pace of construction for SLS means that, if funded, it will likely take a decade at least for it to launch these six capsule/service modules. Since SpaceX’s Starship/Super Heavy will likely be operational in about half that time, and will also be capable of much more for far less, I suspect that if these additional Orion capsules get launched, they will do so on something other than SLS.

ESA funds ArianeGroup prototype vertical landing hopper

4:57 pm

The European Space Agency (ESA) has now committed 33 million euros for ArianeGroup to develop a prototype vertical landing hopper dubbed Themis that would begin testing first stage landings by ’23.

ArianeGroup and its collaborators in Belgium, Switzerland, France and Sweden offer critical technical knowhow gained through the development of Europe’s next-generation engine – Prometheus – which will power Themis.

ESA’s Prometheus is a highly versatile engine capable of providing 1000 kN of variable thrust and is reignitable which makes it suitable for core, booster and upper stage application. An onboard computer handles engine management and monitoring in real time – a crucial feature for reusability.

ArianeGroup is the private consortium led by Airbus and Safran that is building Ariane 6. This deal suggests that ESA amd ArianeGroup has finally recognized that Ariane 6, built without reusability, is a lemon and is not attracting customers. This new contract starts the process of developing a reusable first stage.

They still might be too late. They will only begin testing the Themis prototype in ’23, with no clarity on when a full scale version will follow. Meanwhile, it is very likely that SpaceX’s fully reusable Starship/Super Heavy will be flying orbital missions by then, and likely charging far less than they presently do for their Falcon 9.

ESA funds construction of its own X-37B, dubbed Space Rider

11:23 am

The new colonial movement: The European Space Agency (ESA) has now signed the contracts to fund the construction of its first reusable mini-shuttle, dubbed Space Rider and comparable to the Air Force’s X-37B.

ESA signed two contracts with industry on 9 December at Palazzo Chigi in Rome, Italy in the presence of Italian government representatives. The first contract is for delivery of the Space Rider flight model including the reentry module and the AVUM orbital service module, by co-prime contractors: Thales Alenia Space Italy and Avio. The second contract covers the delivery of the ground segment by Italian co-prime contractors: Telespazio and Altec.

Activities are on track for the first flight of Space Rider in the third quarter of 2023 from Europe’s Spaceport in French Guiana.

Like the X-37B, Space Rider will provide Europe with a space platform for performing long term experiments in space and recovering them undamaged, though initially the flights will be no more than two months long. While it will launch on a rocket like the X-37B, and will use its body to shed velocity as it returns through the atmosphere, it will not land on a runway but will instead use parachutes to drop it to the ground.

More importantly, Space Rider will be available to the private sector. The X-37B is controlled by the U.S. military, and they have made it available for only a limited number of non-military experiments.

New Gaia data release tracks distance and motion of 1.8 billion stars

10:49 am

The European Space Agency (ESA) today released the third round of data from its Gaia satellite, designed to measure precisely the distance and motion of billions of nearby stars.

Gaia EDR3 contains detailed information on more than 1.8 billion sources, detected by the Gaia spacecraft. This represents an increase of more than 100 million sources over the previous data release (Gaia DR2), which was made public in April 2018. Gaia EDR3 also contains colour information for around 1.5 billion sources, an increase of about 200 million sources over Gaia DR2. As well as including more sources, the general accuracy and precision of the measurements has also improved.

This release also included the following discoveries:

  • The Milky Way’s outer regions beyond the Sun contain two populations of stars, one slowly dropping towards the galaxy’s plane, the second flying away quickly.
  • The first precise measure of the solar system’s orbit in the Milky Way
  • A more complete census of all stars within 100 parsecs of the Sun
  • A better map of the interaction between the Large Magellanic Cloud and the Milky Way, which also showed that the cloud does have a spiral structure

This precise data will take decades to digest, as past research has been based on only rough distance and motion estimates. Having precise data will change our approximation of each object’s brightness, which will also change much of what we assume about it.

ESA signs contract for 1st space junk removal

9:39 am

Capitalism in space: The European Space Agency (ESA) has now signed a contract with a private company, ClearSpace SA, for the first dedicated commercial mission to remove a piece of orbiting space junk.

ESA officials signed a contract with ClearSpace on Nov 13. to complete the safe deorbiting of a payload adapter launched aboard the second flight of the Arianespace Vega rocket in 2013.

Unlike traditional ESA contracts that involve the agency procuring and coordinating the mission, ClearSpace-1 is a contract to purchase a service: the safe removal of a piece of space debris. ESA officials said they intend this mission to help establish a new commercial sector led by European industry. The 86 million euros supplied by ESA will be supplemented with an additional 24 million euros ClearSpace is raising from commercial investors. Approximately 14 million euros of the privately-raised funding will be utilized for the mission, while the remaining 10 million will be set aside for contingencies, ESA spokesperson Valeria Andreoni told SpaceNews.

First, that the ESA has decided here to shift from running the mission and to merely being the customer buying the product from a private company is magnificent news. Europe has been, like NASA was in the 2000s, very reluctant to give up its total control in the design, construction, and launch of rockets and spacecraft. That they are now mimicking NASA’s own shift in the 2010s to this private model, as I outlined in detail in Capitalism in Space, means that ESA’s bureaucracy is finally coming around to the idea of freedom, capitalism, and private enterprise. What a thing!

Second, though this mission is commercial, it isn’t really a practical economic solution to the removal of most space junk. The contract will cost $104 million, plus the additional private capital ClearSpace has raised. None of this appears to include the launch cost. Yet, it will only remove one defunct object in orbit.

Such a technology will be useful for removing specific large pieces of space junk that pose a risk should they crash to Earth. It will not be economically useful for removing the small junk in orbit that threatens other working satellites and spacecraft. For that technology to be cost effective it will need to be able to clean up many objects on a single flight.

ESA maps out first launch schedule for new rockets

3:19 pm

Capitalism in space? The European Space Agency (ESA) today laid out the development roadmap that will lead to the launch of two new rockets, the Vega-C being built by the Italian company Avio, and the Ariane 6 being built by ArianeGroup.

The Vega-C is a more powerful version of the Vega rocket, aimed at capturing the smaller satellite market. It maiden flight is now scheduled for June ’21.

The Ariane 6 is aimed at replacing the Ariane 5, Europe’s big workhorse rocket, but to do so at a lower cost. Its maiden flight is now set for the second quarter of ’22, a significant delay from the previously announced target date in ’21, which itself was a delay from the original late ’20 launch date.

Ariane 6 however has not succeeded in cutting costs enough to match its competitor SpaceX, and thus it continues to have trouble attracting customers, even among ESA’s partner nations that it is meant to serve. These issues have led to rumors that ESA is already looking to either significantly upgrade Ariane 6 (before it even flies), or replace it entirely wit a new re usable rocket.

NASA and ESA ink Lunar Gateway deal

9:09 am

NASA yesterday announced that it has signed a deal with the European Space Agency (ESA) outlining their partnership in building the Lunar Gateway space station in orbit around the Moon.

Under this agreement, ESA will contribute habitation and refueling modules, along with enhanced lunar communications, to the Gateway. The refueling module also will include crew observation windows. In addition to providing the hardware, ESA will be responsible for operations of the Gateway elements it provides. ESA also provides two additional European Service Modules (ESMs) for NASA’s Orion spacecraft. These ESMs will propel and power Orion in space on future Artemis missions and provide air and water for its crew.

For some reason NASA’s press release makes no mention of what ESA gets from the deal. From this news report:

[ESA] said it will receive “three flight opportunities for European astronauts to travel to and work on the Gateway” as part of the agreement.

I also note that there is no mention of the Artemis Accords in this agreement. As far as I can tell, right now the only ESA member who has signed on is the United Kingdom, and I am not sure of the UK’s status in the ESA considering their exit from the European Union. The two are different political deals, but exiting one might affect the other.

The Trump administration has said repeatedly that it will only partner in its lunar ambitions with countries that sign the accords. However, at this moment Congress has simply not funded those ambitions, so NASA needs partners to get things built. Moreover, Orion is a space capsule (costing about $18 billion and taking 20 years to build) that does not have a service module to provide it air and water. Europe provides that, and had only agreed to build two.

It might be that NASA has traded the accords away to get Europe’s help for both Gateway and Orion. This deal, announced now, might also be an effort by NASA (and Europe) to lobby Congress to fork up the cash.

Mercury probe BepiColombo probe flies past Venus

9:44 am

Venus during BepiColombo fly-by
Click for full image.

The two-pronged European and Japanese probe BepiColombo today has completed its first of two fly-bys of Venus on its way to an arrival at Mercury in 2025.

The image to the right is one of 64 taken during the fly-by. The science team has created a movie from those images, showing Venus slide past as the spacecraft slewed to view it. During the fly-by the instruments on board its Japanese and European orbiters, both of which will separate and operate independently once they reach Mercury, gathered data of Earth’s sister planet.

The spacecraft still needs one more Venus fly-by plus six past Mercury to get it on a trajectory that will put it in orbit around Mercury. It has also already completed one fly-by past Earth in this complicated route.

COVID-19 and launchpad issues delay Ariane 6

10:00 am

The European Space Agency (ESA) confirmed today that the first launch of Arianespace’s Ariane 6 rocket will be delayed at least six months, to late 2021, due to lock downs related to the Wuhan flu panic, as well as construction issues at the rocket’s new launchpad.

“While we know that the maiden flight will not take place before the second semester of 2021, we cannot at this moment precisely quantify the delay, and we cannot provide an exact launch date,” Daniel Neuenschwander, ESA’s director of space transportation, said according to an ESA translation of remarks at a July 9 press event provided to SpaceNews. The French Association of Professional Journalists in Aeronautics, organized the event at ArianeGroup’s headquarters in Paris.

ESA hopes to have greater clarity on the delays in a few months, he said, according to the ESA translation.

It bodes bad for this rocket that they, at this time, have so little handle on the issues and the length of the delays.

ArianeGroup developing new rocket engine

9:35 am

Capitalism in space: The private company ArianeGroup has now gotten the okay from the European Space Agency (ESA) to begin full development of its new Prometheus rocket engine, intended to reduce costs 10x.

By applying a design-to-cost approach to manufacturing Prometheus, ESA aims to lower the cost of production by a factor of ten of the current main stage Ariane 5 Vulcain 2 engine. Features such as variable thrust, multiple ignitions, suitability for main and upper stage application, and minimised ground operations before and after flight also make Prometheus a highly flexible engine.

This Prometheus precursor runs on liquid oxygen–methane which brings high efficiency, allows standardisation and operational simplicity. Methane propellant is also widely available and easy to handle.

Essentially, ArianeGroup is going to try to build its own methane-powered rocket engine, having seen the success that SpaceX has so far had with its own Raptor methane engine. This also signals an increased recognition at ESA and ArianeGroup that their new Ariane-6 rocket, whose first launch is still about a year away, is not going to be competitive with SpaceX’s offerings, and needs to be upgraded or replaced.
