The SKAO’s Director-General, Prof. Philip Diamond, travelled to Western Australia to represent the Observatory at the site of the future SKA-Low telescope. Council Chair Dr Catherine Cesarsky attended the event in South Africa’s Northern Cape province where the SKA-Mid telescope will be located.

In her address, Dr Cesarsky said: “The SKA project has been many years in the making. Today, we gather here to mark another important chapter in this 30-year journey that we’ve been on together. A journey to deliver the world’s largest scientific instrument. After 18 months of intense activities around the world, we are starting construction of the SKA telescopes.”

Over the past 18 months, over 40 contracts worth more than €150 million have been entered into by the observatory. On Monday, major new construction contracts worth over €300 million were announced at the ceremonies.

Minister Ed Husic from Australia and South Africa’s Dr Blade Nzimande announced more than €200 million for Australian and South African companies to deliver some of the extensive infrastructure required for the telescopes. 

The SKAO also announced the major contracts – worth €100 million – to manufacture the antennas for both telescopes, bringing the total amount of construction funds allocated so far by the observatory to close to €500 million.

In their announcements, the science ministers elaborated on the contractual conditions that the SKAO placed on infrastructure providers to include local communities. 

In South Africa, the lead infrastructure contractor is required to spend a proportionate amount locally by providing a range of sub-contract opportunities to local SMMEs, on employing, training and transferring skills locally and on other community development initiatives. 

In Australia, the aim is to create nearly 100 new roles for the Wajarri Yamaji and locals in the Mid West region of Western Australia.

The Indigenous Land Use Agreement recently signed between the Wajarri Yamaji and the Australian federal and Western Australian governments as well as CSIRO, expanded Inyarrimanha Ilgari Bundara, the CSIRO Murchison Radio-astronomy Observatory to enable construction of the SKA telescope there. 

The agreement ensures that Wajarri Yamaji cultural heritage will stay protected and that they will receive sustainable and intergenerational benefits in areas such as enterprise and training and education. About 400 km of ground was surveyed to map areas of cultural significance, and the layout of the SKA telescope array was amended to avoid significant Wajarri heritage sites.

In recognition of the agreement, the Wajarri gifted the site the traditional name – Inyarrimanha Ilgari Bundara, meaning “sharing the sky and stars”. 

“We want to be good neighbours to all of the local stakeholders where our infrastructure is located,” said Prof. Diamond. “It’s important that we play our part in supporting the local economy as well as the national one, and we’re doing our small part to ensure this is the case. For example, we’ve instructed infrastructure contractors to ensure local businesses are engaged and benefit from those contracts as well.”

Italy: Minister of University and Research, Anna Maria Bernini  

“Finally, the SKA radio telescope is no longer a mere project but a reality. The largest telescope in the world, with thousands of antennas spread across two continents, is destined to define our present and our future. It is one of the most ambitious projects ever undertaken, and I am particularly proud to be able to say that this project is very much tied to Italy. Right from the onset, Italy has played a leading role through its National Institute of Astrophysics. Italy contributes to the project not only financially and in terms of technology but, first and foremost, through its excellent human resources. Something in which we are leaders. The SKA Observatory is a demonstration that Italy has all the resources to participate fully in space exploration from the ground. This is truly an extraordinary endeavour. We are taking a fundamental step towards a broader understanding of the laws that govern the universe. And perhaps also towards broadening our view of the World. As our Latin ancestors would say, ‘per aspera ad astra’. My best wishes for a fruitful exploration.”

We are as the UK very proud to be one of the three host partners of the SKA Observatory and I'd like to congratulate colleagues in South Africa and Australia on achieving this latest milestone and helping us to bring one step closer operation of this really exciting observatory. After construction completion, the two complementary telescopes will be the ears on either side of the planet allowing us to listen to those murmurings from the deep universe, which are driving such excitement in both science and deeper our understanding of the universe in which we live and the origins of life. As the home of the control centre for the Observatory, the UK is helping lay the foundation for new galaxy-level discoveries through radio astronomy. Scientists, engineers and researchers across UK industry and academia are working to deliver the working brain if you like behind these two telescopes, the software systems which make space observations possible and allow us to make sense of what we see and hear. All of these efforts help to channel more funds, jobs, careers, opportunities and innovation, both into the UK economy, but just as importantly, into the global commercial space science and space economy.”
