Arianespace aims for 14 launches in 2018

The competition heats up: Arianespace officials told reporters today that it plans to complete 14 launches in 2018, which would be a record for the company.

For 2018, the company is targeting seven launches of the Ariane 5 model, four launches for the Soyuz model and three launches of the Vega satellite launcher.

Isn’t competition wonderful? SpaceX forces everyone to lower their launch prices, and instead of going out of business, which the old rocket companies were saying would happen for decades should they be forced to drop prices, everyone gets more customers, more business, and more profits. I am shocked, shocked!

Whether Arianespace can maintain this growth however is another story. As newer rocket companies, such as Blue Origin, come on line with even lower costs, I am not sure their more expensive rockets will survive.

ArianeGroup to begin production of first Ariane 6 rocket

Capitalism in space: Having completed a new review of the design of its new Ariane 6 rocket, ArianeGroup and ESA have decided to begin production for a planned launch in 2020.

I continue to wonder how they expect this expendable rocket to compete for launch business with both SpaceX and Blue Origin flying reusables by 2020. At best, I see the member states of the European Space Agency saddled with the requirement to use this more expensive rocket, which will seriously handicap them in the competition to settle the solar system.

Europe commits $107 million for new rocket and space plane

The European Space Agency (ESA) today allocated $107 million to develop both a new larger version of its Vega rocket as well as an orbital version of the spaceplane engineering test vehicle flown in 2015.

The Vega-E will be larger and will give them another rocket capable of competing for launch business, but the space plane project is more interesting.

ESA awarded 36.7 million split between Avio and Thales Alenia Space Italy for Space Rider, an unmanned spaceplane capable of lifting 800 kilograms to LEO for missions up to two months. A single Space Rider should be capable of six missions with refurbishing, according to Thales Alenia Space.

Space Rider leverages technology from ESA’s Intermediate Experimental Vehicle (IXV), which performed a suborbital mission in February 2015, landing in the Pacific Ocean. Unlike its predecessor, Space Rider is designed for ground landings. ESA tasked Thales Alenia Space with building Space Rider’s reentry module based on the IXV.

It seems Europe wants its own version of X-37B and Dream Chaser.

Europe finally begins to realize that reusability cuts costs

Capitalism in space: Faced with stiff and increasing competition from SpaceX, European governments are finally beginning to realize that their decades of poo-pooing the concept of rocket reusability might have been a big mistake.

In what was likely an unexpected question during a Nov. 19 interview with Europe 1 radio, French Economy and Finance Minister Bruno Le Maire was asked if SpaceX meant the death of Ariane.

“Death? I’m not sure I’d say that. But I am certain of the threat,” Le Maire said. “I am worried.” Le Maire cited figures that are far from proven — including a possible 80% reduction in the already low SpaceX Falcon 9 launch price once the benefits of reusability are realized. “We need to relfect on a reusable launcher in Europe, and we need to invest massively in innovation,” Le Maire said.

Then there was a report out of Germany that has concluded that SpaceX commitment to reusability is about to pay off.

The article also cites those in Europe and with the U.S. company ULA that remain convinced that they can compete with expendable rockets. In reading their analysis, however, I was struck by how much it appeared they were putting their heads in the sand to avoid facing the realities, one of which has been the obvious fact that SpaceX has been competitively running rings around them all. This is a company that did not even exist a decade ago. This year it very well could launch more satellites than Europe and ULA combined.

ESA to lead international effort to track falling Chinese space station

The European Space Agency has taken the lead position in an international effort to track China’s falling Tiangong-1 test space station module.

The goal of the effort is to improve the accuracy of predicting the fall of such objects. Tiangong-1, at 8.5 tons, is big enough for some pieces to survive re-entry and crash to the ground. Improving the predictions of where it will fall will reduce the chances of the debris causing harm.

I first read of this effort from this news story, which contained in its last sentence one piece of interesting news having nothing to do with Tiangong-1:

The next such launch [of a Chinese space station module] will be of the Tianhe core module around 2019 on a new Long March 5B rocket, the country’s largest and most powerful so far. [emphasis mine]

It appears China has quietly renamed its big Long March 5 rocket, adding a “B” to the name. This name change strongly indicates what I have suspected for months, that the July launch failure has required China to significantly redesign the rocket. Apparently, the poor performance of the rocket’s first stage engines was caused by fundamental design problems.

Motor for ArianeGroup’s next generation rockets ready for testing

Capitalism in space: The first full scale solid rocket motor for ArianeGroup’s next generation rockets, the Ariane 6 and the Vega-C, is now ready for testing.

The P120C is the largest solid-propellant rocket motor ever built in one segment. Each P120C will hold over 140 tonnes of propellant in a carbon fibre casing almost 11.5 m long and about 3.4 m in diameter. It is derived from Vega’s current first stage motor, the P80, which holds 88 tonnes of propellant.

The design builds on existing expertise and lessons learned with Vega’s P80, and it increases Vega performance with Vega-C. Two or four P120Cs will be strapped onto Ariane 6 as boosters for liftoff.

The use of this solid rocket on both the upgraded Vega-C and the larger Ariane 6 illustrates how the privately controlled ArianeGroup is trying to reduce costs. In the past, Arianespace would have had different companies within the ESA build different solid rockets for Vega-C and Ariane 6 in order to distribute the work to different member countries, even though having two different development contracts would have increased costs.

Canadian Inuit officials demand halt to rocket launch

The coming dark age: Canadian Inuit officials are demanding that the launch of a European atmospheric research satellite by a converted Russian ICBM be stopped out of fear of the pollution it might cause.

The position of the rocket company is based on calculated engineering:

In a statement to CBC News, the European Space Agency insisted the fuel won’t reach Earth’s surface. “Please remember that under standard pressure, hydrazine boils at 113.5 C,” the agency said. The stage containing the fuel will re-enter Earth’s atmosphere much hotter than that, it said. “The structural parts lose their integrity and by melting the destruction of the stage occurs. The agency said that six kilometres above the ground “the propellant components have completely burnt up.”

The position of the protesters is based on fear and lack of knowledge:

The concern for Inuit is the rocket’s second stage, which contains hydrazine-based fuel and is expected to splash down in the North Water Polynya. Though it’s outside of Canada and Denmark’s international waters, it’s home to a vast array of birds and marine mammals that Inuit rely on for food.

“It’s the birthing ground of all the animals that we eat, that people in the North depend upon,” said Eva Aariak, Canada’s commissioner on the Inuit Circumpolar Council and former Nunavut premier. “I know it’s being played down in terms of the kind of effect it would have, but nobody knows. This is the most concerning part is that nobody really knows. And before people know exactly what kind of effect it can have, we will keep fighting.” [emphasis mine]

The article also interviews a pro-Inuit scientist whose primary evidence apparently comes from a youtube video.

There is no doubt that hydrazine is very toxic, which is why it is generally not used as the launch fuel for rockets. However, these protests appear based on mindless fear, almost like the protesters were primitive tribesman afraid of thunder. Ah, but maybe that is exactly what they are!

ArianeGroup struggles with the concept of reusability

Capitalism in space: ArianeGroup, the company building ESA’s next generation rocket Ariane 6, is debating when and if it should introduce reusability into its design.

[Patrick Bonguet, head of the Ariane 6 program,] said ArianeGroup is studying reusability with Prometheus “in order to be sure to take the right path at the right moment.” Those efforts are mostly to prevent Europe from being caught flat-footed in the wake of other reusable launch systems, namely from SpaceX and now also Blue Origin.

Reusability is far from a primary focus, however. “We still have not understood, would we save money by reusing? At least with our launch rate?” he asked. “We hope to launch 12 times a year. If we reuse 12 times, that means we only manufacture one time per year. It is difficult for us to have that.”

Bonguet said reusability would essentially erase the production efficiencies ArianeGroup is striving for, starving the Ariane 6 industrial base of the work upon which it relies. A smaller tip-toe into reusability could come through salvaging Ariane 6’s payload fairings. Swiss manufacturer Ruag Space is developing reusable fairings, which Bonguet said are of interest to ArianeGroup.

I guarantee that by the mid-2020s they will entirely be “caught flat-footed” if they have not begun by then the use of reusable rockets.

ArianeGroup’s transition to Ariane 6 rocket

Link here. It appears that this transition not only includes replacing Ariane 5 with Ariane 6, but also the phase out of Russian Soyuz rockets by 2022. This loss of business is going to hurt Russia, as the government there desperately needs cash with the drop in oil prices.

The article also noted that ArianeGroup will charge two prices for Ariane 6, depending on configuration and payload, $85 million and $130 million per launch. These prices seem high, but because they likely cover the launch of two satellites, customers will be charged half these amounts, $40 million and $65 million, which is competitive in today’s market.

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 below 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.

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.

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.

ExoMars’ Trace Gas Orbiter images Phobos

As part of its checkout, Europe’s ExoMars’ Trace Gas Orbiter has taken test images of the Martian moon Phobos.

The camera imaged the moon on 26 November from a distance of 7700 km, during the closest part of the spacecraft’s orbit around Mars. TGO’s elliptical orbit currently takes it to within 230–310 km of the surface at its closest point and around 98 000 km at its furthest every 4.2 days. A colour composite has been created from several individual images taken through several filters. The camera’s filters are optimised to reveal differences in mineralogical composition, seen as ‘bluer’ or ‘redder’ colours in the processed image. An anaglyph created from a stereo pair of images captured is also presented, and can be viewed using red–blue 3D glasses.

The images were done to test the spacecraft’s operation, and have apparently shown that it is functioning well.

ESA approves ExoMars 2020 funding

Despite the failure of the Schiaparelli lander on ExoMars 2016, the European Space Agency today approved funds to build and fly the ExoMars 2020 rover mission.

At a meeting of European government ministers in Lucerne, Switzerland, on 1 and 2 December, ESA member states agreed to provide an extra €339 million for ExoMars 2020. ESA also announced that it will find a further €97 million by moving funds internally. Speaking at a press briefing after the meeting, ESA director-general Jan Wörner said this would be done “without detriment” to ESA’s wider science budget.

But not all projects were so fortunate. Member states did not commit the €250 million needed to fund a plan for ESA to participate in a mission to deflect the moon of an asteroid, although they left door open to future, similar projects.

I am not at present sure how they are going to divide up the work between Europe and Russia. Earlier it was my understanding that Russia would provide the roving technology, but right now I am very unsure about this.

One side note: At this same meeting ESA committed to sticking with ISS through 2024.

Dispute in ESA over Schiaparelli failure

Prior to the release of ESA’s preliminary report on the failure of Schiaparelli, the Italian space agency had claimed the problem was caused by the failure of a Romanian subcontractor to do sufficient simulations and testing.

ESA released the preliminary conclusions after the Italian Space Agency had accused that the decisive tests for the Sciaparelli lander simulations had been entrusted to an organization “which hadn’t enough expertize”. It’s about Arca Space Romanian company, based in Las Cruces, USA, as La Repubblica reported.

In retort, the Arca Space Corporation manager, Dumitru Popescu warned the Italian space agency to be more careful, as they don’t have proves to support their accusations. “They could pay the price. We are at ease that we did all we could do: to run a specific test we should have flown very closely to the Russian base in Sevastopol. Russia has just annexed Crimea and we risked generating a conflict between the Russian Federation and NATO,” the Romanian manager argued.

There is something fishy here, but I’m not sure what. That they didn’t do a test because they feared instigating an international incident with Russia does not seem right. In fact, this whole story suggests that the very management structure of ESA, designed to spread work to as many of its partner nations as possible, is the fundamental source of the problem.

Software error caused Schiaparelli crash

A new ESA report says that the ExoMars 2016 Schiaparelli lander failed because its navigation system thought the lander was on the ground when it was still more than two miles from the surface.

Europe’s Schiaparelli Mars lander crashed last month after a sensor failure caused it to cast away its parachute and turn off braking thrusters more than two miles (3.7 km) above the surface of the planet, as if it had already landed, a report released on Wednesday said.

Figuring out what caused this failure will be helpful for the design of the ExoMars 2020 rover, but the failure here is likely going to make it more difficult for Europe to raise the money needed for that next mission, including a 400 million euro cost overrun.

Fate of Schiaparelli remains unknown

While Europe’s Trace Gas Orbiter has successfully gone into orbit around Mars, it remains unknown whether the lander Schiaparelli was able today to land successfully on the surface.

The carrier signal from Schiaparelli recorded by Mars Express abruptly ended shortly before landing, just as the beacon tone received by a ground-based radio telescope in India stopped in real-time earlier today.

Paolo Ferri, head of ESA’s mission operations department, just gave an update on the situation. “We saw the signal through the atmospheric phase — the descent phase. At a certain point, it stopped,” Ferri said. “This was unexpected, but we couldn’t conclude anything from that because this very weak signal picked up on the ground was coming from an experimental tool.

“We (waited) for the Mars Express measurement, which was taken in parallel, and it was of the same kind. It was only recording the radio signal. The Mars Express measurement came at 1830 (CEST) and confirmed exactly the same: the signal went through the majority of the descent phase, and it stopped at a certain point that we reckon was before the landing.

“There could be many many reasons for that,” Ferri said. “It’s clear these are not good signs, but we will need more information.”

ExoMars 2016 in detail

This Nature article provides a nice summary of the European/Russian ExoMars 2016 mission that on Wednesday will try to place a lander on Mars as well as put an orbiter in orbit.

Neither probe is going to provide many exciting photos. The orbiter, dubbed boringly the Trace Gas Orbiter, is designed to study Mars’ atmosphere, while the lander, Schiaparelli, is essentially a technology test mission for planning and designing what Europe and Russia hope will be a more ambitious lander/orbiter mission in 2020.

Anyone expecting spectacular pictures from Schiaparelli itself might be disappointed — photos will be limited to 15 black-and-white shots of the Martian surface from the air, intended to help piece together the craft’s trajectory. No photos will be taken on the surface, because the lander lacks a surface camera.

Schiaparelli’s instruments will study the Martian atmosphere, including the possible global dust storm that might happen this month but so far has not yet appeared. The instruments will also be able to detect lightning, should it exist on Mars.
