I would like to PrepSKA received full funding for 3 years thank ASTRON in Dwingeloo for their from the European Commission to conduct generous hosting of the ISPO Director and a work program to (i) integrate the world- support staff for the last 5 years, and wide R&D effort on the SKA into a costed CSIRO-ATNF for their likewise generous system design, (ii) carry out further site hosting of the International Project characterisation including deep RFI Engineer. measurements at the candidate core sites, (iii) investigate options for governance structures for the SKA, (iv) investigate procurement issues and the involvement of industry in the development and construction of the telescope, and (v) to investigate options for construction funding. Funding for the 4th year, foreseen in the PrepSKA proposal for the system design work, will be sought at a later date. This is a fantastic result, and full credit to Phil Diamond and his global team for bringing this off. Commitment of the matching funds is in progress. PrepSKA will start formally on 1 April 2008, with most of the senior engineers in the Central Design Integration Team (CDIT), funded by PrepSKA, in action in Manchester as soon as possible thereafter.

Finally, I’m sure you will all join me in saying thanks to Peter Hall for his outstanding leadership of the international 3 NEWS FROM THE WORKING GROUPS ENGINEERING The engineering component of the SKA deliver the SKA, it’s clearer than ever that project has made considerable progress progress in overcoming our key design over the last 12 months. Along with challenges is likely to emerge from the substantial technical innovation within less-than-defined “twilight zone” between regional Pathfinders and Design Studies, pure astronomy, engineering, operations as an international project we are now set and probably a number of other to embark on a central design and disciplines. integration exercise via the PrepSKA program. Before starting PrepSKA, the At the operational engineering level, the engineering community was keen to see a previous EWG Newsletter report listed in set of preliminary SKA specifications to detail a number of important activities, guide the new Central Design and including performance-cost modelling.

I’m very excited about my new role as foundation Professor of Radio Astronomy It is very gratifying to see that as the SKA Engineering at Curtin University in Perth, project progresses, we remain strong in and I look forward to working closely with our ability to work effectively and cordially the whole SKA community in coming across national and discipline boundaries. years. My own view is that this will be incredibly important in the years ahead. For example, as we rightly strive to build the Peter Hall formal structures and processes needed to International Project Engineer, and Chair EWG.
