EADS : Astrium rachète SSTL

EADS Astrium, la division aérospatiale d'EADS, a annoncé avoir signé un accord avec l'université britannique du Surrey pour l'acquisition du constructeur de petits satellites Surrey Satellite Technology Limited (SSTL). L'université a décidé de céder sa participation majoritaire d'environ 80% dans cette société pour un montant non communiqué. SSTL emploie 270 personnes et a réalisé un chiffre d'affaires de l'ordre de 26 millions de livres en 2006-2007 (exercice clos fin juillet).

L'opération reste soumise à l'approbation des autorités de régulations compétentes.

L'achat de SSTL par EADS est bon a mon avis. EADS etait bon pour Astrium UK. SSTL va rester independent d'un point des operations mais ils ont plus d'argent pour R&D etc... .

Astrium's Assurances Sealed Deal for SSTL Acquisition

By Peter B. De Selding

The founder and managing director of British small-satellite builder Surrey Satellite Technology Ltd. (SSTL) said he personally endorsed the company's sale to Astrium, a large satellite conglomerate, because of guarantees from Astrium that SSTL would remain independent — even when it competes with Astrium.

In an April 10 interview, Sir Martin Sweeting said Astrium, owned by Europe's largest aerospace company, EADS, gave specific assurances to the British government and the British Defence Ministry that SSTL's corporate culture would not be overwhelmed in the Astrium bureaucracy.

"Negotiations on the sale of SSTL have been going on for six months, and I talked to all the bidders," Sir Martin said. "The bids were all fairly good in financial terms, but Astrium gave the most specific assurances about our continued independence."

In an agreement announced April 7, Britain's University of Surrey, which owns a majority of SSTL, and Astrium Satellites announced that Astrium would be buying the successful small-satellite builder.

In addition to purchasing almost all of the university's SSTL ownership, Astrium will be buying the 10 percent of SSTL owned by Space Exploration Technologies of Hawthorne, Calif., and the 5 percent stake owned by SSTL employees. All three transactions are being concluded on the same terms and conditions. Industry officials valued the all-cash transaction at around 45 million British pounds ($89.7 million).

The university will retain a symbolic 1 percent share of SSTL's equity after the sale, which is pending approval by British and European regulators.

Astrium had approached SSTL several years earlier about a possible sale and had been rejected on the grounds that a large enterprise like Astrium, one of the world's biggest satellite builders, would smother SSTL.

But in 2007, SSTL and the university concluded that their relationship had to end if SSTL was to be allowed to grow. The company has built 27 satellites since 1981 and has 13 more on order. In recent years it has been slowly increasing its presence in the commercial market, and has found itself in need of loan guarantees and other financial backing that the university could not provide.

The university's director of corporate services, Greg Melly, said the university naturally was looking to monetize its more than two decades of investment in SSTL. But it equally was determined not to put the company into the hands of a buyer that would destroy SSTL.

In an April 7 interview, Melly agreed with Sir Martin that Astrium's assurances about its intentions for SSTL were broader and deeper than any other bidder's, irrespective of the financial terms.

"We are not commercially naïve," Melly said. "But we are hugely proud of the success of this company, and the buyer's integrity, its approach to the market, where it competes — all this was key to us. Astrium gave us more assurances about how this would be done than anyone else."

Sir Martin will remain with the company, and SSTL will have an independent board of non-executive directors that will not be appointed by Astrium, Melly said. Sir Martin confirmed that he has no intention of leaving SSTL.

Melly and Sir Martin said Astrium gave specific guarantees about SSTL's expected bid to build at least some of the 26 Galileo satellite navigation satellites to be contracted by the European Commission and the European Space Agency later this year.

Astrium, led by its German division, is bidding to build all 26 Galileo spacecraft, and SSTL has indicated it might bid with OHB System of Bremen, Germany, for some of the satellites.

For Astrium, the profitability of a contract to build 26 identical satellites likely would be far superior to a contract for 15-20 satellites.

Nonetheless, Astrium has promised that SSTL will be allowed to make a bid. "We've had those assurances quite categorically," Sir Martin said. "The [European Commission] is looking to open competition for Galileo, so if SSTL doesn't bid [against Astrium], someone else will. So from Astrium's point of view, it would be better to have a competing supplier that you own than a competing supplier that you don't own." While SSTL and Astrium occupy different market sectors — Astrium concentrates on large satellites, space infrastructure and government business in Britain, France and Germany — they have found themselves in competition with increasing frequency.

Astrium's French division has developed, with the French government, a line of small satellites for Earth observation and science that competes with SSTL's famously low-priced product. At the same time, SSTL has begun development of larger satellites, hoping to apply its low-cost program management to bigger contracts.

Astrium spokesman Jeremy Close said the company already has proven its ability to give subsidiaries a broad independence with Tesat Spacecom of Germany, a builder of satellite components and laser communications terminals that occasionally competes with Astrium.

"The Tesat model is the one we are applying here," Close said April 7. "We think the Tesat history gives us credibility when we say we are determined to let SSTL continue to do what it does best."

SSTL reported revenue of 26 million British pounds for the fiscal year ending July 31, with a net profit of 1.2 million pounds. Sir Martin forecast that SSTL's current backlog would generate revenue of slightly less than 46 million pounds for the fiscal year ending in July, with a net profit of slightly less than 3 million pounds.

PICTURE: UK built SpaceX capsule revealed

By Rob Coppinger

Details have emerged of the UK's first commercially designed and built manned capsule that was delivered in 2005 to US customer Space Exploration Technologies (SpaceX), but did not fly. SpaceX had planned to launch a production version on its Falcon 5 rocket.

Above: The Magic Dragon capsule before its shipment to SpaceX

Kept secret until now, the five-crew capsule, called Magic Dragon, was designed by UK engineer Andy Elson for a three-day journey to take crew or cargo to the International Space Station and also act as an ISS emergency return vehicle.

Each of the capsule's five seats had a touchscreen laptop computer and supported the body and calf muscles during lift-off, with foot rests designed to fold away after launch. In its cargo version, without seats, it was to have carried three ISS pallet racks.

UK built SpaceX Magic Dragon capsule

The interior of the Magic Dragon capsule

Magic Dragon had an ISS common berthing module (CBM) at one end and a combined heatshield/propulsion unit at the other. The propulsion unit's exit cones' rims were to have been flush with the Falcon 5's heat-shield leading edge. The Falcon 5 has now been superseded by SpaceX's Falcon 9 booster.

SpaceX had specified a powered descent that did not use parachutes. The propulsion unit was also to have acted as a launch abort system during a rocket malfunction. The combined heatshield/propulsion unit was wider than the capsule for re-entry aerodynamics and atop this crew module, covering the CBM, was the Falcon 5's foldaway nose cone.

Elson, who has built pressurised capsules for high-altitude balloons, says there was originally a three-man capsule, but SpaceX chief executive Elon Musk decided "in October or September 2004 he wanted a five-person capsule".

The US government's International Traffic in Arms Regulations issues caused difficulties for Elson. He was unable to obtain details of the CBM or even basic Falcon 5 dimensions from SpaceX, a situation complicated by a lack of information about the combined heatshield/propulsion unit Elson was not designing.

SpaceX's next launch of its Falcon 1 rocket with its new Merlin 1C first-stage engine is scheduled for June from the company's central Pacific Marshall islands' Kwajalein Atoll launch site. The payload will be for the US Department of Defense's operationally responsive space office. This third flight of the Falcon 1 was to have taken place earlier this year.

Positive results encourage further UK Stern rocket work

By Rob Coppinger

A rocket nozzle that delivers optimal thrust across a much wider range of altitudes and which could be used for a UK spaceplane concept is to be tested again this year. This follows analyses of four 1s firings in February and March that indicated a successful outcome.

In theory rocket engines with an expansion, deflection (ED) nozzle should provide increased performance in atmospheric flight as the nozzle compensates for the effect of the changing ambient pressure, maximising thrust.

The nozzle's test rig is called the Static Test Expansion/Deflection Rocket Nozzle (Stern) motor and its four firings were part of a long-term programme by Culham, Oxfordshire based-Reaction Engines to understand how ED works.

Funded by Reaction Engines and built by UK company Airborne Engineering, the University of Bristol helped develop and test the 30kg (66lb) Stern rocket engine that produces 1,100lb thrust (5kN).

Because its combustion chamber reaches 2,100°C (3,800°F) the firings have to be limited to less than 2s otherwise the chamber wall would melt.

"The nozzle is designed to test our computer models. We want to design the tool for developing the ED nozzle to go on [Reaction Engines' Sabre engine]," says consultant to Stern, Bristol University space technology senior lecturer Mark Hempsell.

The test rig was built in 12 months. Hempsell will not disclose Stern's cost. Reaction Engines funded the research as it would like to use the ED nozzle on its Sabre engine.

This hydrogen, air-fuelled engine would power the company's horizontal take-off, horizontal landing Skylon spaceplane concept.

The ED nozzle is calculated to deliver sufficiently more thrust during take-off so that its payload could be increased by 500kg and the runway length shortened by 500m (1,600ft).

The Stern test rig also used igniter and injector designs for the Sabre. An analysis of the engine's performance suggests these worked as expected.

Ion engine enters space race

By Helen Briggs

Science reporter, BBC News

The test chamber is one of the biggest in Europe

Engineer Neil Wallace peers into a huge vacuum chamber designed to replicate - as far as possible - the conditions of space.

Cryogenic pumps can be heard in the background, whistling away like tiny steam engines.

Using helium gas as a coolant, they can bring down the temperature in the vacuum chamber to an incredibly chilly 20 Kelvin (-253C). The pressure, meanwhile, can drop to a millionth of an atmosphere.

This laboratory in a leafy part of Hampshire is where defence and security firm Qinetiq develops and tests its ion engines - a technology that will take spacecraft to the planets, powered by the Sun.

Ion engines are an "electric propulsion system". They make use of the fact that a current flowing across a magnetic field creates an electric field directed sideways to the current.

This is used to accelerate a beam of ions (charged atoms) of xenon away from the spacecraft, thereby providing thrust.

Neil Wallace, technical lead of the electrical propulsion team at Qinetiq, winds open the door of the testing chamber.

The most exciting time for us will be when that space craft comes over the horizon

Neil Wallace, Qinetiq

He points to some large metal blocks at the bottom of the chamber.

"These are the xenon pumps and these are cooled down by the helium compressors to approximately 20 degrees Kelvin," he explains.

"So any gas atoms that strike those panels, they freeze. After you've been running the engines for a number of hours you can see a frost - it looks like snow - which is actually frozen air and xenon."

During testing, the engine fires ions towards the opposite end of the chamber, which has a protective coating of graphite.

"The ions are travelling very fast, at approximately 50km a second," he says.

"When they strike the other end of the chamber, they actually knock atoms off the surfaces they strike; it's analogous to sand-blasting on an atomic level."

Cruise control

The ion engine developed by Qinetiq, the T5, will be flown for the first time on the European Space Agency's Goce spacecraft. The mission will fly just 200-300km above the Earth, mapping the tiny variations in its gravity field.

GOCE - EUROPE'S GRAVITY EXPLORER

Goce (BBC)

1. The 1,100kg Goce is built from rigid materials and carries fixed solar wings. The gravity data must be clear of spacecraft 'noise'

2. Solar cells produce 1,300W and cover the Sun-facing side of Goce; the near side (as shown) radiates heat to keep it cool

3. The 5m-by-1m frame incorporates fins to stabilise the spacecraft as it flies through the residual air in the thermosphere

4. Goce's accelerometers measure accelerations that are as small as 1 part in 10,000,000,000,000 of the gravity experienced on Earth

5. The UK-built engine ejects xenon ions at velocities exceeding 40,000m/s; Goce's mission will end when the 40kg fuel tank empties

6. S Band antenna: Data downloads to the Kiruna (Sweden) ground station. Processing, archiving is done at Esa's centre in Frascati, Italy

7. GPS antennas: Precise positioning of Goce is required, but GPS data in itself can also provide some gravity field information

'Space arrow' to map Earth's tug

A replica of the T5 engine sits in the test facility at Qinetiq. It is tiny - weighing 3kg, and looks rather like the oil filter of a car.

Yet despite this humble appearance, it took 20 to 30 years to develop, at a cost of tens of millions of pounds.

In space, ion engines will draw electric power from solar panels, generating a thrust equivalent to the weight of a postcard.

This incredibly gentle thrust could, in theory, take a spacecraft beyond our Solar System, if sustained for long enough.

Goce is staying very close to Earth, flying in an ultra-low orbit, where it will encounter wisps of air.

The benefit of an ion engine on this mission is to provide drag compensation, or cruise control.

"This spacecraft is [travelling] at a speed of about eight and a half kilometres per second," says Neil Wallace.

"As it travels around the Earth, it's going through the upper atmosphere and it experiences a buffeting.

"They need to compensate that buffeting very accurately and that's what we're doing, so we're actually providing cruise control for that spacecraft."

Real flight

Various types of ion engine have been used before on only a handful of space missions, including Smart-1, the European mission to the Moon, and Nasa's Deep Space 1, which flew by a comet.

The T5 ion engine being tested

Future Esa missions such as BepiColombo, bound for the innermost planet, Mercury, will also use the technology.

Qinetiq gets to test its T5 engine for real this summer, when Goce is launched from the Russian space port of Plesetsk. It will go up on the same type of rocket that failed three years ago, destroying Europe's Cryosat ice mission.

Neil Wallace says the nature of the space business makes watching any launch a dramatic event.

"You spend 10 years working on a mission, treating the components and equipment like a newborn baby. You never take it out of the clean room, and then you put in on the top of 100 tonnes of high explosive and set light to it," he says, laughing nervously.

"But no, the most exciting time for us will be when that spacecraft comes over the horizon and the ground station picks it up, and you can see the engines are doing what we've always said they will do."

Missile practice for Moon mission

By Judith Burns

BBC News

Penetrator missiles were fired into a wall of sand at 1,100km/h (700mph)

Tests on a UK-led technology at the heart of a planned Moon mission have been a spectacular success, according to the experts involved in the project.

Three penetrator missiles were fired into a sand bunker in Wales, designed to mimic the lunar surface.

Professor Alan Smith, of the Mullard Space Science Laboratory, told BBC News the results had exceeded expectations.

He is a leading figure in the Moonlite mission, which hopes to fire instruments into the Moon in 2013.

A BBC team witnessed the final day of the tests at the Ministry of Defence (MoD) test site at Pendine, near Tenby.

The site has been open since 1940 but is now operated by Qinetiq, the privatised MoD spin-off company which developed the penetrator technology.

Three projectiles were tested on three consecutive days at the end of May.

They look like missiles but, rather than exploding on impact, they are designed to stay intact to protect the scientific instruments inside.

An animation of the penetrator missile hitting the lunar surface

The Moonlite mission plans to fire four penetrators into the lunar surface from an orbiting spacecraft. They will come to rest three metres (10ft) underground.

The onboard instruments will send back a mass of information, everything from seismic activity and mineral composition to the underground temperature.

Sand blasted

Security at Pendine was tight - we had to show passports to gain entry. The high-speed test track is set in a large area of sand dunes paradoxically full of birds and flowers.

Professor Alan Smith explains how the penetrator missiles are tested

It's a hard hat site; during the firing itself, all staff must take cover. We were actually confined to the control centre.

Earlier, we saw scientists loading instruments into the third and final penetrator to be tested.

The purpose of the test firings was to check how well the penetrators would withstand being slammed into several tonnes of sand at 1,100km/h (700mph) and whether the instruments inside would survive.

The difference between the penetrators that had already been fired and the one that had yet to be tested was striking.

The blue paint on the fired ones was scraped off and the steel nose cones were distorted.

But despite their battered appearance, Peter Truss of Qinetiq confirmed that they had done their job and protected the instruments inside: "our confidence is growing with every test".

Qinetiq not only contributed to the missile derived design of the penetrators themselves, but to the batteries and communication systems they will carry.

Ultimately, the plan will be to apply this technology to other rocky planets and moons in the Solar System, particularly to Jupiter's icy moon Europa, which may have an ocean below its frozen surface.

Other candidates include Saturn's moons Titan and Enceladus.

Deep space

Until now, missions have only been able to scrape the surface of other planets.

"We're developing the technologies now to enable a much more in-depth analysis of these planetary bodies and with the increase in technology that we can apply to these problems, all sorts of possibilities open up," explained Peter Truss.

The other advantage of penetrators is that it's easier to fire into a rocky planet than to land gently on the surface.

Loading and safety checks complete, the penetrator was driven out to the test track. This stretches 1,500m through the sand dunes but the penetrator and its rockets were strapped to a firing sled 300m from the target.

We retired to the control room and looked on as scientists waited anxiously for the final countdown. When it came, the firing shattered the quiet with a reverberating bang. There were cheers from the scientists at the completion of the last test.

Then it was time to break cover and head down to the sand bunker with a metal detector and some shovels to locate the penetrator and dig it out. Researchers measured how far it had pushed into the sand and collected samples.

In each test, the penetrators described a curved trajectory upwards through the sand, ending up only slightly below the surface.

Intruigingly, they also turned the sand they touched black, possibly as a result of its high coal content reacting to the heat.

Speaking later, back at the Mullard Space Science Laboratory, Professor Smith said Nasa and the European Space Agency were showing interest.

"The results have been spectacular and the space agencies are sitting up and taking notice," he said.

"Before now it had all been on paper. Now we have real hardware to show them."

Astrium wins satellite contract worth €263 million

WEBWIRE – Tuesday, May 27, 2008

Berlin. – Europe’s leading space company, Astrium, has been commissioned by the European Space Agency (ESA) to develop and build the EarthCARE Earth observation satellite. The contract worth € 263 million was signed today in Berlin on the occasion of the International Aerospace Exhibition (ILA) by Volker Liebig, ESA’s Director of Earth Observation, Evert Dudok, CEO of Astrium Satellites and Uwe Minne, Director of Earth Observation and Science at Astrium (Friedrichshafen, Germany), in the presence of German Chancellor Angela Merkel, ESA Director General Jean-Jacques Dordain and Head of the German Aerospace Centre (DLR) Johann-Dietrich Wörner.

EarthCARE (Earth Clouds, Aerosols and Radiation Explorer) will focus on clouds, tiny particles in the atmosphere – aerosols – and their influence on atmospheric radiation. Among other things, EarthCARE will draw up vertical profiles of natural and man-made aerosols, register the distribution of water and ice and their transport by clouds, and investigate the interrelationships between clouds and precipitation and their effects on radiation. It will be possible to derive profiles of atmospheric heating and cooling by clouds from a combination of the measured aerosols and “cloud elements”.

“The role of aerosols in cloud formation and the interaction with radiation is not completely understood by science but plays an important role in climate and weather modelling. This is why the EarthCARE proposal was selected” said ESA’s Earth Observation Director Dr. Volker Liebig.

EarthCARE will thus contribute to a better understanding of our climate and deliver valuable data for the numerical forecasting models of climate researchers and meteorologists. Weighing around 1.7 metric tons, the satellite is scheduled to lift off into space in September 2013. EarthCARE will spend three years taking measurements from a polar orbit (97° inclination) at an altitude of about 400 kilometres.

“By offering an innovative and future-oriented range of products, Astrium is helping to achieve a better understanding of Earth’s sensitively balanced ecosystem and encourage people to treat it with greater care,” said Astrium Satellites CEO Evert Dudok to journalists in Berlin. “The experience and know-how gained from projects such as EarthCARE or the recently awarded contracts for the Sentinel family of satellites and the polar-orbiting weather satellite Metop give us an excellent basis and serve as a reference for future tasks such as the third generation of Meteosat satellites.”

Astrium (Friedrichshafen, Germany) will be responsible for the industrial management of EarthCARE and the integration and test activities. The satellite is equipped with four instruments, two passive and two active sensors that will supply a unique data package with only one satellite mission. Astrium (Toulouse, France) will supply the active laser instrument ATLID, while the platform (Astrium), the Multi-Spectral Imager MSI (SSTL) and the Broadband Radiometer BBR (SEA) are being produced in the UK. The fourth instrument is the Cloud Profiling Radar CPR, which will be supplied by the Japanese Space Agency, JAXA.

Astrium and the Earth Explorer

EarthCARE is the sixth Earth Explorer mission to be launched by ESA as part of its “Living Planet” Earth exploration programme. It is being implemented jointly with the Japanese space agency JAXA. Astrium is the prime industrial contractor.

Astrium also plays an important part in the other satellites for Earth Explorer missions that are currently under construction. Astrium (Friedrichshafen) is prime contractor for the ice investigation satellite Cryosat-2 and the three-satellite Swarm mission to investigate the Earth’s magnetic field. It is also supplying the platform for the Goce mission to measure the Earth’s gravitational field. Astrium UK is the prime contractor for the ADM-Aeolus wind mission, for which Astrium France is developing the Aladin instrument. Astrium Spain is developing and building the Miras payload for the SMOS mission to study soil moisture and ocean salinity.

BRUXELLES (Reuters) - EADS a reçu le feu vert de la Commission européenne pour acquérir, via sa filiale néerlandaise, le fabricant britannique de satellites Surrey Satellite Technology Limited (SSTL).

L'exécutif communautaire indique dans un communiqué avoir considéré que les activités des deux entités se chevauchaient essentiellement dans le domaine de la fabrication de satellites d'observation de la terre, mais que l'opération n'entraverait pas de manière significative la concurrence sur ce marché.

Sur le marché européen des appels d'offres institutionnels, où les deux entreprises sont également présentes, la Commission dit être parvenue à la conclusion que cette acquisition par le groupe européen d'aéronautique n'éliminera du marché aucun concurrent réel ou potentiel important d'Astrium.

EADS est présente dans le secteur spatial principalement par l'intermédiaire de sa filiale Astrium, qui conçoit, développe et fabrique des systèmes de satellites.
