Reports of another ExoMars parachute failure during test

9:09 am

Following a failure of ExoMars’ parachutes during a May test, there are now reports that a second failure occurred on August 5.

A fresh test of the parachute system for the Russian-European mission ExoMars-2020 have failed again as a structural mockup of the Russian-built lander crashed during the simulated landing, a source familiar with the test results told Sputnik.

The test with the use of a high-altitude balloon was carried out on August 5 at a Swedish Space Corporation’s test site in northern Sweden.

“Tests of the parachute system at the Esrange test site in Sweden failed. A full-size mockup of the landing module of the ExoMars-2020 Martian station crashed during the landing,” the source said.

I have seen this report in two other sites, but it has not yet been confirmed by the European Space Agency.

If these reports are true, the chances of ExoMars launching in July 2020 is likely almost nil. They haven’t even begun assembling the spacecraft, and have had two parachute failures in tests, with the second destroying the prototype used for those tests.

SpaceX and Arianespace complete successful launches

9:58 pm

Today, as I was giving my lecture in Denver, both Arianespace and SpaceX successfully completed launches.

SpaceX put a commercial communications satellite in orbit. The first stage was not recovered, but this was intended. The company however was successful in catching one half fairing in the giant net of its recovery ship Mrs. Tree., the second time they have done so.

Arianespace used its Ariane 5 rocket to launch a commercial communications satellite and a European Space Agency data relay satellite.

The leaders in the 2019 launch race:

12 Russia
11 China
10 SpaceX
6 Europe (Arianespace)
4 India

The U.S. now leads Russia 16 to 12 in the national rankings.

Europe completes 1st rollout of Ariane 6 mobile launch gantry

9:32 am

The mobile launch gantry that Europe will use for its new Ariane 6 rocket successfully completed its first rollout tests last week.

This gantry is the equivalent of NASA’s VAB building. Within this gantry they will assemble Ariane 6 vertically, then roll the gantry back for launch.

Assembling a rocket vertically I think is more costly, but it also makes it possible for the rocket to launch payloads that must be installed in this manner. Thus, Ariane 6 will have this selling point over rockets like the Falcon 9 and Falcon Heavy, which are assembled horizontally.

Europe’s Galileo GPS-type constellation back up and running

7:35 pm

Europe’s Galileo GPS-type constellation was back up and running on July 18, though it remains unclear exactly what caused the failure in both of its ground facilities.

Officials have only provided this tantalizing hint:

“The technical incident originated by an equipment malfunction in the Galileo control centers that calculate time and orbit predictions, and which are used to compute the navigation message,” the GSA wrote on Thursday in its most specific statement yet. “The malfunction affected different elements on both centers.”

That generally confirms what researchers who use the Galileo system had noticed independently. Satellites transmit packages of data to Earth that convey a set of astronomical positioning and timing data, used to compute satellite orbits and positions. But some combination of errors in the Galileo processing system led it to base these calculations on the wrong date, for example, using July 11 time stamps—the day the outage began—throughout the week. Eventually, the system even interpreted this data as referring to July 18, instead of the previous Thursday. The frozen time stamp seemed to be a symptom of problems with the ground-based processing system, rather than the satellites themselves.

This sure sounds like a computer hack that took down the systems at both facilities, suggesting that the security of Europe’s Galileo system has some very big holes.

Update on Europe’s Galileo GPS-type constellation failure

8:57 am

Link here. Key quote:

A new source has told Inside GNSS that the ongoing Galileo outage “…has to do with the Precise Time Facility (PTF), a redundant facility present in both Italian and German control centers.” This is the second source close to the program who has identified the PTF as the focus of the incident. Our source adds, “Incidentally, the redundancy apparently did not work.” So, the suggestion is that both PTFs, at two separate European locations, have failed. And, our source adds, “Take into account that the two major outages in the last two years were also caused by problems in the PTF. There are major architectural problems within the GMS [Galileo Mission Segment] under Thales Alenia Space…responsibility.” [emphasis mine]

The article does not go into any details how it is possible for two redundant facilities to fail at the same time. It does note however that while the U.S.’s GPS, Russia’s Glonass, and China’s Beidou systems all are operated by the military, which takes very seriously security, Europe’s Galileo is not.

Europe finally admits it must build reusable rockets

8:56 am

The new colonial movement: Europe has finally admitted that its refusal with Ariane 6 to make it reusable was a mistake, and has begun a major engineering research project to design and fly two different types of reusable rockets.

This month, the European Commission revealed a new three-year project to develop technologies needed for two proposed reusable launch vehicles. The commission provided €3 million to the German space agency, DLR, and five companies to, in the words of a news release about the project, “tackle the shortcoming of know-how in reusable rockets in Europe.”

This new RETALT project’s goals are pretty explicit about copying the retro-propulsive engine firing technique used by SpaceX to land its Falcon 9 rocket first stages back on land and on autonomous drone ships. The Falcon 9 rocket’s ability to land and fly again is “currently dominating the global market,” the European project states. “We are convinced that it is absolutely necessary to investigate Retro Propulsion Assisted Landing Technologies to make re-usability state-of-the-art in Europe.”

What is interesting to me is what appears to be some internal politics within Europe surrounding this effort. France is generally the most dominate member of the European Space Agency. Yet, according to the press release for this announcement, France is not involved in these new reusable rocket projects. Instead, Germany dominates, with companies from Switzerland, Portugal, and Spain participating.

It could be that the failure of Ariane 6 to garner customers, due to its higher costs, has forced these ESA partners to push for their own reusable rocket projects.

Either way, the competition in rocket technology is heating up, more evidence that the 2020s will be the most exciting decade in space since the 1960s.

Ireland’s government releases its space strategy goals through 2025

9:01 am

The new colonial movement: Ireland today released a national space strategy designed to encourage the growth of a commercial space sector by 2025.

You can download the actual report here [pdf].

They want to increase both public and private investment by 50% by 2025. Whether that means investment in private companies or simply a growth in a government bureaucracy is uncertain, based on my reading of the report. It appears their goal is to grow the private sector, but they will be using European Space Agency approaches for doing so, which tend to favor government growth and control rather than developing an independent commercial industry.

ESA moves forward on building its own reusable X-37B

10:29 am

The European Space Agency (ESA) has approved the preliminary design reviews for its reusable mini-shuttle, dubbed Space Rider, that they hope to launch by 2022.

Launched on Vega-C, Space Rider will serve as an uncrewed high-tech space laboratory operating for periods longer than two months in low orbit. It will then re-enter the Earth’s atmosphere and land, returning its valuable payload to eager engineers and scientists at the landing site. After minimal refurbishment it will be ready for its next mission with new payloads and a new mission.

Essentially this is Europe’s X-37B, but developed for commercial customers rather than the military. In fact, it suggests that Boeing, the builder of X-37B, is missing a major market by not developing its own commercial X-37B.

Europe inaugurates ExoMars control center

8:15 am

The Europe Space Agency yesterday inaugurated the control center where it will control and download data from the ExoMars rover, Rosalind Franklin, scheduled to launch to Mars in the summer of 2020.

The control center also includes a dirt filled enclosure where they can simulate Martian conditions with a rover model.

The article outlined the project’s upcoming schedule:

Over the summer the rover will move to Toulouse, France, where it will be tested in Mars-like conditions. At the end of the year Rosalind Franklin will travel to Cannes to meet the landing and carrier modules for final assembly.

As I noted yesterday in my most recent rover update, this assembly, only six months before launch, gives them very little margin. If there are any problems during assembly, they will likely miss the 2020 launch window.

I also wonder if this will allow them any time to do acoustical and environmental testing, as was just completed on NASA’s 2020 rover, to make sure ExoMars can survive launch, landing, and the journey to Mars. If they forego those tests, they might discover after launch that they were launching a paperweight, not an expensive planetary probe.

ArianeGroup begins production of first 14 Ariane 6 rockets

9:15 am

Capitalism in space? ArianeGroup has announced it has begun production of the first fourteen Ariane 6 rockets, set for launch beginning in 2020.

Following the initial institutional and commercial launch orders for Ariane 6 obtained by Arianespace since the autumn of 2017, and the resolution of the ESA Council on April 17, 2019, related to the rocket’s exploitation framework, ArianeGroup is starting to build the first series-production batch of 14 Ariane 6 launchers.

These 14 launchers, scheduled to fly between 2021 and 2023, will be built in ArianeGroup plants in France and Germany, as well as in those of its European industrial partners in the 13 countries taking part in the Ariane 6 program.

The April 17 resolution essentially committed the ESA (European Space Agency) to subsidize ArianeGroup should Ariane 6 fail to obtain sufficient launch contracts for the company to make a profit.

Right now, that subsidization seems almost certain, based on the prices ArianeGroup is charging for Ariane 6 and the resulting dearth of sales contracts.

The launch rate announced above illustrates the rocket’s lack of interest. Fourteen launches in three years? SpaceX has been launching that many times in half a year. Granted, Ariane 6 is designed to launch two satellites to Falcon 9’s one, but even so this launch rate is low. And I expect in reality it will be lower than this. I expect them to fail to get launch customers, and will find they have a white elephant on their hands.

ESA agrees to subsidize Ariane 6 should it fail to sell

9:57 am

The European Space Agency (ESA) has signed an agreement with ArianeGroup, the private company building its next generation rocket Ariane 6, to provide subsidizes to the company should the rocket’s inability to get launch contracts continue.

The problem is that ESA had promised ArianeGroup seven launch contracts from its various governments during the rocket’s development, but only three so far have been signed. Ariane 6, though less expensive than Ariane 5, still costs too much (it is not going to be usable), and it appears that too many member nations in ESA don’t want to pay the extra bucks when they can get the same service cheaper from SpaceX.

This lack of contracts has caused ArianeGroup to slow development.

The new agreement gives the company a financial guarantee should the additional four launch contracts not materialize.

“If seven launch service contracts are not signed by the ministerial at the end of November, then the ESA DG [Director General Jan Woerner] will propose for decision to member states to complement the revenues needed for the first Ariane 64,” said [Daniel Neuenschwander, ESA’s director of space transportation].

In other words, Ariane 6 is going to turn out just like Ariane 5, an expensive rocket that never makes a profit. Moreover, if ESA requires its members to use its cost will handicap Europe’s future space efforts.

This isn’t a surprise. I predicted this likelihood back in September 2017 when ArianeGroup first announced the prices it planned to charge for Ariane 6 launches. Those prices, for launches in the 2020s, were higher than what SpaceX charges now, and were certainly going to be more uncompetitive in the future.

It seems that Europe’s aerospace industry, both in and out of government, can’t seem to understand these basics of the free market. You have to be competitive, and if you are not, the worst way to fix the problem is pour more money into an uncompetitive product. From the get-go they designed Ariane 6 as if it was 1990, when the industry said reusable rockets were impossible. The result is a rocket no one wants to buy, because everyone knows that by the mid-2020s they will have many inexpensive reusable rockets to choose from. Why buy an overpriced dinosaur?

So, instead of pouring subsidies into Ariane 6, as designed, ESA should be demanding for its money new designs from ArianeGroup that make the rocket cheaper to launch.

Europe does not appear to be doing this, however, so expect Europe to be badly crippled in the upcoming 21st century space race.

Spanish company completes parachute drop test of reusable first stage

7:09 pm

The new colonial movement: A Spanish company funded by the European Space Agency (ESA) has successfully completed a drop parachute test for recovering the first stage of their smallsat rocket from the ocean.

A Chinook CH-47 helicopter lifted the 15 m long 1.4 m diameter Miura 5 demonstration first stage to an altitude of 5 km then dropped it over a controlled area of the Atlantic Ocean, 6 km off the coast of Huelva in southern Spain.

During the descent, electronic systems inside the demonstrator controlled a carefully timed release of three parachutes to slow it down until its splashdown at a speed of about 10 m/s.

A team of divers recovered the demonstrator and hoisted it onto a tugboat, which returned to the port of Mazagón. The demonstrator looks to be in good shape and will now be transported to PLD Space, in Elche, for inspection and further analysis.

They next say they will develop a vertical landing system, similar to SpaceX’s.

Honestly, this seems like a waste of money and somewhat foolish. SpaceX made it very clear almost a decade ago when they tried to recover first stages out of the ocean after using parachutes to splash down softly that the salt water did too much damage to the engines and made such recovery impractical.

I can’t help asking, why is ESA spending time and money supporting engineering tests of a design that simply won’t work? They should be doing tests now of vertical landing technology, since it does work, and in fact is what they need to compete successfully.

Maybe I am being too harsh. Maybe they want to develop vertical landing technology that will work in conjunction with these parachutes, and this is merely their first step. Maybe. Based on past ESA development projects (which are often as dysfunctional as NASA’s), I think my doubts are not unreasonable.

Auditor condemns Ariane 6

10:30 am

Capitalism in space: France’s independent government auditor has issued a new report that badly slams Arianespace’s next generation rocket, Ariane 6, accusing its design as being too cautious and too expensive, thus guaranteeing it will fail to compete with the reusable rockets now in use as well as being developed in the U.S.

This is the scathing assessment of France’s independent state auditor in a report that picked apart the flawed economic model behind Ariane 6, the next generation of rocket-launchers set to start operating in 2020.

It made the point that Europeans, who have taken part in developing the launcher, went for a “cautious” approach and invested in the kind of controlled technology that potential clients in the continent had no faith in, even back in 2014. This means that Ariane 6 is stuck in the past and “risks not being competitive over the long term.” Its U.S. rivals are way ahead and already testing future disruptive technologies. [emphasis mine]

The highlighted text is proven by the apparent unwillingness of Arianespace’s European partners to sign contracts for Ariane 6.

This isn’t really news. See for example this February 13, 2018 report on Behind the Black. Or this one from September 2017, where ArianeGroup first outlined the prices they expected to charge for Ariane 6. Then, I predicted what France’s auditor has only now realized:

Will these prices be competitive in 2020s? I have my doubts. I estimate, based on news reports, that SpaceX is charging about $40 million today for a launch with a reused first stage, and $62 million for a launch with an entirely new rocket. Give them another five years of development and I expect those prices to drop significantly, especially as they shift to entirely reused first stages for almost every launch and begin to demonstrate a routine launch cadence of more than one launch per month.

This quote…explains how ArianeGroup really intends to stay alive in the launch market: “The price targets assume that European governments — the European Space Agency, the European Commission, Eumetsat and individual EU nations — agree to guarantee the equivalent of five Ariane 62 missions per year, plus at least two missions for the light-lift Vega rocket.”

In other words, ArianeGroup really doesn’t wish to compete for business. It wants to use government coercion to force European space agencies and businesses to buy its product. They might get that, but the long term result will be a weak European presence in space, as everyone else finds cheaper and more efficient ways to do things. [emphasis mine]

Based on recent stories, it seems that ArianeGroup has been unable to force European space agencies to buy Ariane 6. Thus, the rocket faces failure, before it even launches.

ArianeGroup successfully test fires new solid rocket motor

9:11 am

Capitalism in space: ArianeGroup, the private consortium building Europe’s next generation of rockets, has successfully test fired the new solid rocket motor it will use for both its Ariane 6 and Vega-C rockets.

The P120C is designed and built by a European consortium involving a joint venture known as Europropulsion, a venture between ArianeGroup and Avio, as well as CNES, the Italian ASI space agency, and Airbus Safran. This multinational venture uses the Avio facilities in Colleferro, Italy to manufacture the carbon fiber composite casing, a facility in France to build the ArianeGroup composite steerable nozzle, and the propellant casting and integration facilities in French Guiana to build up and prepare these boosters for flight.

The P120C, through its common use across launch vehicle lines and use of existing facilities, is designed to reduce costs as a competitive response to newer companies like SpaceX that have dramatically lowered launch costs and captured an increasing share of the worldwide launch market, dethroning the ArianeGroup from the dominating position it had held until very recently.

Without doubt they are going to save money using this solid rocket motor on both rockets. I remain somewhat skeptical, however, about whether they will achieve enough cost savings to compete with SpaceX. The seeming lack of interest by their primary European customers for Ariane 6 suggests this. It appears that its price might still be too high.

Arianespace slashes launch price for Ariane 5

9:10 am

Capitalism in space: Arianespace has announced that it is once again dropping the launch price for an Ariane 5 launch, in order to increase the chances it will win several contracts this year.

Arianespace is competing for two major launch contracts in the Asia-Pacific region that should be awarded this year and expects there could be tenders for another three, said [Arianespace Managing Director and Head of Sales for Asia-Pacific Vivian Quenet].

The article does not mention the actual price, but Arianespace had been charging about $100 million per launch satellite, while SpaceX had been charging $62 million (for a new Falcon 9) and about $50 million (for a reused one).

Ariane 6 might be in trouble

8:25 pm

Capitalism in space: Arianespace today announced that they will not be able to begin full production of their next generation rocket, Ariane 6, unless they get four more contracts from the partners in the European Space Agency.

With the maiden flight of the Ariane 6 now 18 months away (in July 2020), Arianespace CEO Stéphane Israël said the company had anticipated signing a manufacturing contract with ArianeGroup in the second part of last year to begin production beyond the first rocket.

So far, European public entities have purchased three Ariane 6 missions — two from the European Commission for launching Galileo navigation satellites, and one from France for the CSO-3 military imaging satellite — but have not committed to the number envisioned at the start of the Ariane 6 program in 2014.

“We are confident it will happen,” Israël said of the remaining government missions. “But it is not done yet. We are working in this direction. It is now quite urgent because industry has anticipated the manufacturing of these first launchers, but now we need these institutional contracts to fully contractualize the first Ariane 6s.”

I wonder if the fact that the cost for an Ariane 6 launch is expected to be remain higher than a comparable SpaceX launch is the reason they are having trouble getting a commitment from their European partners. Why buy this rocket, when you can get the same service for less?

BepiColombo begins first operational engine burn

9:09 am

The European/Japanese mission to Mercury has begun the first operational firing of its four ion engines, set to last for the next two months.

This might seem like a ridiculously long burn, since most conventional rocket engines fire for minutes, not months. These are ion engines, however, far more efficient but producing a very tiny acceleration. It takes a long time for their burns to accumulate a velocity change.

ESA plans Vega rocket upgrades

9:33 am

In order to grab more market share, the European Space Agency today outlined a wide range of upgrades and options it is creating for its Vega rocket.

The article describes versions aimed at the smallsat market, the geosynchronous satellite market, and a recoverable mini-shuttle similar to the X-37B, dubbed Space Rider. All these options are expected to come on line by 2021.

Isn’t competition wonderful? Threatened by loss of market share by SpaceX, Europe has been forced to up its game, something it had been loath to do for decades.

ArianeGroup to cut 2300 jobs

8:48 am

Capitalism in space: Faced with a significant loss of market share, taken by SpaceX, the European rocket manufacturer ArianeGroup has announced it will reduce its staffing by 2,300 jobs by 2022.

A joint venture by European aerospace company Airbus and the French group Safran, it currently employs 9,000 people in France and Germany. Constructor of the Ariane rockets, the European Space Agency workhorse, ArianeGroup also produces ballistic missiles.

Ariane 5 rockets are soon to be replaced by the Ariane 6 which will be an estimated 40 percent cheaper to make, under pressure in particular from Elon Musk’s SpaceX.

But European buyers have so far ordered only three Ariane 6 rockets ahead of the first scheduled launch in 2020.

The article at the link, produced by a French news service, is somewhat amusing. It repeatedly blames the lack of demand for the Ariane 6 on the U.S. government, which provides business to SpaceX. It doesn’t mention that ArianeGroup’s Ariane 6 rocket meanwhile is being built with government funds from the European Space Agency, and once completed in the 2020s will have a launch price that exceeds that of the Falcon 9 today. No wonder it hasn’t garnered many customers.

Europe picks landing site for its ExoMars 2020 rover

4:32 pm

The European Space Agency (ESA) has chosen the landing site for its ExoMars 2020 rover, a generally flat area with scattered craters dubbed Oxia Palum.

After over 4 years of careful study of HiRISE and more recently CaSSIS images Oxia Planum was chosen because scientists were convinced that its fine grained sediments, deposited during the ancient Noachian epoch were ideally suited for the Exobiology rover. With an enormous catchment area the sediments will have captured organics from a wide variety of environments over a long period of time, including areas where life may have existed. The fine sediments should also be ideal for the ExoMars drill – it aims to get to 2 metres depth.

Remote identification with the Mars Express and Mars Reconnaissance Orbiter Infrared spectrometers shows the presence of clays and other minerals giving clues to its aqueous history. A large group of scientists have been working on proposing, characterising and down selecting the sites, all of which had fascinating aspects, but Oxia Planum is the clear winner on both science and engineering constraints.

Based on my analysis of the last two candidate sites, I would guess that they also picked Oxia Planum because it is less spectacular, flatter, and thus poses less risk. It also means the images from there will be a bit more boring for the ordinary person.
