ESA buys the first Ariane 6 launches

The European Space Agency (ESA) has purchased the first two Ariane 6 launches to place four of its Galileo GPS satellites in orbit in the 2020-21 timeframe.

This is not a big surprise, since ESA is mandated to use Arianespace’s rockets, and the space agency is the obvious candidate for making the first commitment to this new rocket’s use.

The press release does not mention the price that Arianespace is charging for these launches, but I suspect it isn’t anywhere near as cheap as they will have to charge to truly private and commercial customers. Essentially, I am willing to bet that this contract award is a bit of crony capitalism, designed to pass some extra cash from ESA to Arianespace.

Arianespace announces new launch contracts

Capitalism in space: Arianespace today announced it has won a new launch contract for two different satellites, bringing its launch manifest to 53.

The press release contains a lot of interesting tidbits:

  • They plan to complete 11 launches in 2017, which is slightly above their yearly average in the past six years.
  • In 2018 they presently have only 7 launches planned, the lowest number since 2013.
  • Of the 53 launches, Ariane 5 will do 17, Soyuz 27, and Vega 9, suggesting a shift away from Ariane 5, which has been the company’s mainstay.
  • The private joint partnership of Airbus and Safran, now called ArianeGroup, has taken control of the business, and has begun streamlining it.
  • Arianespace has now been relegated to only handling “customer relations” and launch operations.

Overall, it looks like this European private/government partnership is doing reasonably well in the new very competitive launch market. I still expect their business to shrink in the coming years, but I think they will be around for awhile.

ESA unveils dual orbiter mission to Mercury

After twenty years of development, the European Space Agency this week finally unveiled the completed dual orbiters that it hopes to launch on a seven year journey to Mercury in October 2018.

The 4,100-kilogram BepiColombo consists of two orbiters that will launch together — the ESA-managed Mercury Planetary Orbiter (MPO) and the JAXA-owned Mercury Magnetospheric Orbiter (MMO). The two spacecraft will be delivered to the orbit around Mercury stacked on top of each other by the Mercury Transfer Module (MTM). During the seven-year journey, the MMO will be shielded from the sun by the MMO Sunshield and Interface Structure (MOSIF), which will also serve as a mechanical and electrical interface between the two orbiters.

“MPO focuses on the planet, the surface and the interior size,” said Reininghous. “The orbit is a polar one — 480km times approximately 1500km — a little bit elliptical but extremely close to the planet as such with a return period of 2.3 hours. The data return is estimated at 1.5 gigabit per year.”

The MMO will focus on the planetary environment including the planet’s atmosphere, according to Reininghous. “The orbit is also polar but far more elliptical — 590 km times approximately 11,700 km. It has a period of 9.3 hours. The data return is approximately 10 percent of what we expect from the MPO.”

The European orbiter is much larger and more expensive, with Japanese probe budget being about a tenth the cost.

According to ESA, the mission took so long to build because in 2004, after about seven years of development, ESA suddenly realized that its orbiter’s thermal protection was inadequate, and required a complete redesign. To me, this is either outright incompetence (they knew from the start they were going to Mercury) or a clever way to extend the funding so that it provides an entire lifetime’s work for its builders. Think about it. Twenty-one years from concept to launch, then seven years to fly to Mercury, and then one to two years in orbit. That’s more than thirty years for this single mission.

Success of test mission paves way for orbiting gravitational wave detector

The success of LISA Pathfinder during the past year to test the technology for building an orbiting gravitational wave detector has now made it possible for Europe to approve construction of the full scale telescope, set to launch in the 2030s.

The LISA Pathfinder mission, launched in late 2015, beat its precision target by a factor of 1,000 and quieted critics who have doubted its potential, says project scientist Paul McNamara, an astrophysicist at ESA in Noordwijk, the Netherlands. “This is not the impossible task that some people believed it was.”

Currently set to fly in 2034, the full-scale Laser Interferometer Space Antenna (LISA) will be the space analogue of the Laser Interfero-meter Gravitational-Wave Observatory (LIGO), two machines in the United States — each with a pair of 4-kilometre-long arms — that first detected the ripples by ‘hearing’ the merger of two black holes. LISA’s three probes will fly in a triangle, millions of kilometres apart, making the mission sensitive to much longer gravitational waves, such as the ripples produced by the collisions of even larger black holes.

The article also notes that the European Space Agency also approved two other large missions, one to launch in 2022 and go the moons of Jupiter, another an X-ray observatory that will launch in 2028.

ESA discovers the wonders of capitalism!

Three stories today illustrate how competition is revolutionizing and energizing the European aerospace industry:

The first two stories are clearly examples of the new competition within the launch industry. The first describes the effort by ESA and Airbus-Safran, a partnership now dubbed ArianeGroup, to get the Ariane 6 rocket built fast and cheaply, under pressure as they are by SpaceX’s lower prices.

The manufacturing consortium is looking for a 40% cost reduction, at least, in the Ariane 6, compared with the Ariane 5. In part that is coming from exploiting new materials and new manufacturing techniques (3D printing, friction stir welding, augmented reality design, etc) and in part by maximising the common use of elements in both the 62 and 64 variants. Avio’s solid-fuelled booster is also the same as the first stage on the company’s Vega rocket, which launches much smaller satellites.

But a big cost saving will come from simply employing fewer people. “There is a transition from Ariane 5 to Ariane 6 (from 2020 to 2023), but from 2024, 2025 onwards – our workforce will be 30% less than today,” explained Hans Steininger, the boss of MT Aerospace, which is making the rocket’s huge metallic propellant tanks.

The second article describes how ESA is suddenly changing its reusable mini-shuttle program from a typical, staid, dead-end research project (where they do a series of test flights with no thought towards using what they learned) to a private mini-shuttle available for lease by researchers of all stripes.

By 2025, ESA officials said, Space Rider could be operating commercially, flying science payloads and bringing them back to Earth for roughly $9,200 per kilogram. Arianespace, the Evry, France-based launch services provider, would likely serve as Space Rider’s operator, offering industry and government customers the opportunity to fill the spaceplane 800-kilogram payload capacity with microgravity science, materials testing, telecommunications and robotics demonstrations.

Previously, the plan had been to test fly this spaceplane without selling its cargo capacity. Now they want to make money on it, right from the beginning.

The third article meanwhile illustrates that the old way of doing things is still a factor in Europe’s space effort. Europe’s Galileo GPS satellite network has been delayed badly by faulty atomic clocks. They are replacing them, and are preparing to resume launches. However, in ordering 8 new satellites they have also decided to keep OHB, the same contractor who provided the faulty atomic clocks, rather than give the contract to a competitor or at least split it between two contractors.

The contract, expected in late 2016, was delayed as the commission and the 22-nation European Space Agency (ESA) debated whether to maintain OHB as Galileo’s sole supplier or to award all or part of the contract to competitor Thales Alenia Space Italia.

In the event, the commission and ESA agreed that the savings realized from ordering recurrent-model spacecraft from OHB, and the schedule assurance this provided, outweighed arguments on behalf of dual sourcing. “Dual sourcing is always important but it needs to be weighed against other program requirements” including cost, said Paul Verhoef, ESA’s director of navigation. Verhoef said ESA and the commission may pursue dual sourcing for the next round of Galileo orders, when a new design will be used for the system’s second generation.

I suspect that as competition continues to prove its worth ESA will move to accept the idea of competition in the building of future GPS satellites. For right now, however, this change was more than this large government bureaucracy could handle.

Europe considers a helicopter drone for future Mars missions

The European Space Agency is considering flying a technology demonstration helicopter drone on a future Mars mission.

Note that they don’t yet have the money to build this, and it appears that they don’t yet have a mission to fly it on. What they have done is just completed a preliminary study, which suggests the idea is feasible. They are now lobbying for more cash to move forward.

3D printing of bricks, using moondust

European engineers have managed to print bricks using simulated moondust and focused sunlight.

The resulting bricks have the equivalent strength of gypsum, and are set to undergo detailed mechanical testing. Some bricks show some warping at the edges, Advenit adds, because their edges cool faster than the centre: “We’re looking how to manage this effect, perhaps by occasionally accelerating the printing speed so that less heat accumulates within the brick. But for now this project is a proof of concept, showing that such a lunar construction method is indeed feasible.”

The video at the link is very unconvincing. While it shows film of the printing process, it does not show film of anyone holding or manipulating the finished bricks. Instead, it shows one or two photos of finished bricks, all of which give the impression that these bricks crumble easily at the edges, I suspect that the bricks are simply too fragile for practical use.

So, is this a proof of concept? Maybe. They have at least shown that 3D printing using materials on the Moon might work.

European push for more space regulations under international law

In the European space community and governmental circles, there appears to be a new push to revise the Outer Space Treaty, focused specifically on increasing the treaty’s regulatory power in the area of large satellite constellations and space junk.

This week [the city of] Darmstadt hosts a closed-door, governmental meeting of the Inter-Agency Space Debris Coordination Committee (IADC). Whether it was planned or not, the IADC is set to discuss a much-needed renewal of international space law, which is, experts admit, rather vague. But how far they will go is anyone’s guess.

…There is a palpable sense that the space community needs enforceable international laws and regulations, rather than – or merely to bolster – its current inter-agency agreements. They’ve served us so far, but few countries have actually signed up to them. That leaves a lot of wriggle-room, especially as space becomes increasingly commercialized.

Most of our space activities are governed by the Outer Space Treaty of 1967. It’s a short document that primarily seeks to ensure space operations are “peaceful” and for the good of all humanity. It is complemented by other agreements, including a set of documents on mitigating space debris. “We have a good, coherent set of justified rules and we don’t intend to alter them drastically,” said Christophe Bonnal of the French Space Agency, CNES, and the International Academy of Astronautics (IAA) in closing remarks last week. “But we will improve them at the IADC meeting to include mega-constellations.”

It appears to me that this is a push-back against Luxembourg’s recent announcement that it is going to request a renegotiation of the Outer Space Treaty to allow for property rights in space. What this article is advocating instead is that the treaty increase its control and regulatory power over private satellite constellations, which at present are not covered by the treaty.

Airbus-Safran gets go-ahead to build first Ariane 6 test rocket

Capitalism in space: The European Space Agency (ESA) has given Airbus-Safran the go-ahead to build the first Ariane 6 rocket, which will be used for ground tests.

It is really important to recognize how this article illustrates the major things that have occurred in how Europe is builds its rockets. Note first that Arianespace is not mentioned at all, even though government bureaucracy has been in charge of ESA’s commercial business for decades. It is not in control any longer and is thus irrelevant. Note also that the design was created solely by Airbus-Safran, and that the only thing ESA did was approve it. The agency did not micromanage it, or revise it, or insist on changes, as would have been the case less than three years ago. Instead, it appears they essentially rubber-stamped it, leaving this work entirely to the private company, which in the end will operate and sell the rocket entirely for profit, while also providing ESA its needed launch vehicle.

At first glance, it appears that the ESA has adopted here the recommendations that I made in my policy paper, Capitalism in space:. In truth, they made these policy changes well before my paper was even written, which helps illustrates forcefully their universal correctness. If you want things built well and efficiently, you give people ownership of their work, you let them create it, and you get out of the way.

Or to use that forgotten word, you let freedom work its magic.

Atomic clocks on 9 of 72 European GPS satellites have failed

The atomic clocks on 9 of the 72 European Galileo GPS satellites, designed to compete with the American, Russian, and Chinese GPS satellites, have failed.

No satellite has been declared “out” as a result of the glitch. “However, we are not blind… If this failure has some systematic reason we have to be careful” not to place more flawed clocks in space, [ESA director general Jan Woerner] said.

Each Galileo satellite has four ultra-accurate atomic timekeepers — two that use rubidium and two hydrogen maser. Three rubidium and six hydrogen maser clocks are not working, with one satellite sporting two failed timekeepers. Each orbiter needs just one working clock for the satnav to work — the rest are spares.

The question now, Woerner said, is “should we postpone the next launch until we find the root cause?”

That they are even considering further launches with so many failures of the same units seems absurd. They have a systemic problem, and should fix it before risking further launches.
