Success in this review aptly named SKA publication, Contact. will enable us to prepare the SKA1 Contact is obviously a movie reference Construction Proposal and Operations but the name also reflects our desire Plan which we intend to submit to to connect the SKA community. As we the SKA Observatory Council, upon emerge from the detailed design phase, its establishment. When the Council move towards the establishment of the approves the proposal and commits SKA Observatory and see construction the agreed funding, SKA will move into on the near horizon, we decided to move the construction phase of the project. away from our two previous newsletters So, the next 15 months or so will be an (one internal to the project, the other exciting period and we will endeavour to aimed externally) to deliver a single share progress and milestones to make magazine which will cover the growing sure you keep up-to-date on the most range of SKA activities around the world. relevant happenings within the project. In this more ambitious format we will I hope you enjoy this new SKA seek articles from across the community, publication. I’d like to thank all the from scientists in SKA science working authors who contributed to the groups, from engineering, design and first issue and I’m sure that our construction teams, from precursor and communications team will welcome pathfinder telescopes and occasionally feedback, suggestions for improvement from our government partners. and of course contributions to this This first issue of Contact is published publication, which is very much yours! at a period of heavy activity as the design teams prepare for the System Prof. Philip Diamond, SKA Critical Design Review, scheduled for Director-General 3 IN BRIEF CHINA HOSTS FIFTH SKA SUMMER SCHOOL IN SHANGHAI BY DR TAO AN (SHANGHAI ASTRONOMICAL OBSERVATORY) & YANG JIE (SKA CHINA OFFICE) A week-long training session involving “We had lectures on hot topics like Supported by China’s Ministry of more than 70 students and young gravitational waves, gamma-ray bursts, Science and Technology, the SKA China scholars in SKA-related fields was fast radio bursts and supernovae, Office, and the Chinese Academy held in Shanghai, China in August. and SKAO Project Scientist Dr Evan of Sciences, the summer school is Using data obtained from the SKA Keane set the students a practical part of China’s consistent efforts precursor and pathfinder telescopes, challenge to search for FRBs,” explains to nurture future talents to work in the summer school focused on the Dr Tao An of Shanghai Astronomical SKA-related fields, and has been search for and study of radio transients.

Northern Cape province at the end of July. At CSIRO, we teamed up with Curtin University The launch was graced by the This year it took place from 29 and ICRAR to celebrate science in Geraldton, the Minister of Higher Education, July to 3 August 2019.
