Letters from the DG, Xavier Barcons

Greetings!

In my last “letter” I talked about the huge range of opportunities and benefits available to ESO’s Member States. Today I’d like to elaborate on how we at ESO work with universities, research institutions and leading companies in our Member States to design and build our telescopes and scientific instruments.

Astronomy is a driving force for humanity, challenging our curious minds and pushing us to make key progress here on Earth and beyond. It’s an inherently innovative discipline, using some of the most advanced technologies and sophisticated techniques available to scientists and engineers, and it constantly urges them to take one step further and come up with creative new solutions.

In order to carry out its ambitious programme of scientific research, ESO designs, constructs and operates the most advanced ground-based astronomical telescopes in the world. Unsurprisingly, the construction of such major facilities usually takes up to a decade or more. ESO has built its facilities at three observatories in Chile: La Silla, Paranal-Armazones and Chajnantor. Creating infrastructures of this size and complexity requires a massive collaborative effort between scientists, engineers and industry partners across the world. Scientific institutes in Member States participate in these massive projects, promoting and organising collaboration and giving them cutting-edge know-how — but ESO also joins efforts with a wide range of industry partners to bring ambitious projects to life. Companies in Member States can receive contracts from ESO, covering all business areas from the provision of services to technical studies to the delivery of advanced equipment.

The collaboration between ESO and industry started many years ago. One of the best known examples is the Very Large Telescope (VLT), the most advanced optical/infrared ground-based facility in the world. Back in 1988, ESO signed a contract with the German company SCHOTT to cast the four giant telescope mirror blanks from the specialised material Zerodur®. SCHOTT has now de facto become the main provider of mirror blanks to ESO. In France, a new optical facility was created at Safran Reosc for polishing the giant mirrors for the VLT, and in Italy a consortium of three companies, the AES Consortium, was formed to construct the main mechanical structures of the four 8.2-metre VLT Unit Telescopes. The fruitful VLT collaboration still endures to this day; the recently-installed Adaptive Optics Facility is a triumph of collaboration between ESO and industry.

In total, over 330 million euros were spent in the ESO Member States for the construction of the VLT. Hundreds of suppliers were involved and more than 70 contracts each exceeding 500 000 euros in value were awarded, covering a wide range of industrial services, from civil works to precision electronics to large-scale glass manufacture.

Another example of a massive and successful collaborative project is the Atacama Large Millimeter/submillimeter Array (ALMA), a 1.3 billion euro project between ESO, North America, and East Asia.

ALMA is a giant telescope composed of 66 high-precision antennas; North America provided 25 of these antennas, East Asia 16, and the remaining 25 were provided by ESO. The ESO antennas were manufactured by the European AEM Consortium, led by French, Italian and German companies participating under a nearly 150 million euro contract, one of the largest ever European industrial contracts for ground-based astronomy.

The Extremely Large Telescope (ELT) is ESO’s current major project, with a budget of 1.15 billion euros. This 39-metre optical/infrared telescope will dwarf all other telescopes. ESO signed the contract for the ELT dome and telescope structure with the Italian ACe Consortium, consisting of Astaldi, Cimolai and the nominated sub-contractor EIE Group. This is the largest contract ever awarded by ESO and also the largest contract ever in ground-based astronomy worth an approximate value of 400 million euros. SCHOTT is again casting the telescope’s mirrors, Safran Reosc will polish the mirrors, the SENER Group will supply the mirror cells, and the FAMES consortium — composed of Fogale and Micro-Epsilon — will provide the edge sensors for the 798 hexagonal segments of the primary mirror. Of course, this is not the end of it; there is still a large number of industrial contracts that need to be placed for the ELT, and so further opportunities for European industry will be available in the coming years. Furthermore, the ELT will be equipped with a wide variety of instruments that will be developed and built by our Member States institutes and companies.

But ESO’s telescopes and instruments aren’t the only ones to benefit. ESO’s projects involve staggering technology and continuous innovation and knowledge gain, offering possibilities for technology and knowledge transfer. Since the science and engineering of these huge astronomical projects is cutting-edge, most of it must be developed from scratch — creating opportunities to start new companies, boost high-skilled employment, and generate substantial added value to our Member States’ economies. Companies working for ESO’s demanding projects often need to develop new skills and capacities; these challenges become assets of the companies afterwards, expanding their business opportunities.

ESO also sets new global benchmarks for size, accuracy, capacity, speed and efficiency of optics, mechanics, sensors, lasers, computing, communication, construction, logistics and other important fields. ESO’s projects offer a clear showcase for industry. They benefit our Member States, our industry partners, the scientific institutes working with us, and even society as a whole. To name just two simple, concrete examples, a broad range of dental treatments stem directly from laser developments in astronomy, and adaptive optics technology in telescopes has been implemented in microscopic techniques to improve resolution and contrasts, as well as in instruments for ophthalmology enabling sharp imaging of the retina.

ESO is the foremost intergovernmental astronomy organisation in Europe and the world’s most productive ground-based astronomical observatory by far. It is supported by 16 countries: Austria, Belgium, Brazil, the Czech Republic, Denmark, France, Finland, Germany, Italy, the Netherlands, Poland, Portugal, Spain, Sweden, Switzerland and the United Kingdom, along with the host state of Chile. ESO carries out an ambitious programme focused on the design, construction and operation of powerful ground-based observing facilities enabling astronomers to make important scientific discoveries. ESO also plays a leading role in promoting and organising cooperation in astronomical research. ESO operates three unique world-class observing sites in Chile: La Silla, Paranal and Chajnantor. At Paranal, ESO operates the Very Large Telescope, the world’s most advanced visible-light astronomical observatory and two survey telescopes. VISTA works in the infrared and is the world’s largest survey telescope and the VLT Survey Telescope is the largest telescope designed to exclusively survey the skies in visible light. ESO is a major partner in ALMA, the largest astronomical project in existence. And on Cerro Armazones, close to Paranal, ESO is building the 39-metre European Extremely Large Telescope, the E-ELT, which will become “the world’s biggest eye on the sky”.
