2021: arranca la construcción de SKA - 31st May 2021
Outline • The science driving the SKA • The SKAO • Science • Design • Construction • SKA Regional Centres (SRCs) • SKAO Key information
The SCIENCE DRIVING the SKA Open key questions in Astrophysics, Astrobiology and Fundamental Physics • Formation of the 1st galaxies in a dark Universe dominated by atomic gas • Evolution of the atomic gas and star formation till the current epoch • Strong Field Tests of Gravity Using Pulsars and Black Holes • Acceleration in the expansion of the Universe not understood yet • Habitable extrasolar planets (proto-planetary disks, biomarkers)

Statement by Minister Pedro Duque after the celebration of the first SKA Council
meeting:
“España da la bienvenida a la creación del Observatorio Internacional SKA, que
culmina un periodo de intensos estudios y diseños, y marca el comienzo de una
nueva etapa en la cual se construirá uno de los telescopios más ambiciosos de la
historia de la astronomía. Estamos orgullosos de haber contribuido a esta
impresionante fase preparatoria, y ahora esperamos participar activamente en la
construcción del Observatorio. Nuestra contribución al SKA estará basada en una
comunidad científica fuerte, estratégicamente posicionada dentro del proyecto con
la intención de jugar un papel importante en el desarrollo de la Ciencia Clave del
SKA, y en una industria bien preparada para llevar a cabo los exigentes desarrollos
que un proyecto de esta magnitud requiere. España está firmemente decidida a
participar, en primera línea, en esta magnífica aventura científica destinada a
revolucionar la astronomía y otros campos científicos y tecnológicos.”

Timeline Scientific preparatory work for SKA
• Present: Transition from Participation in Science Working Groups
•
design to construction
• Use of pathfinder/precursor telescopes
• 2021: construction approval • Preparation for commissioning
by IGO Council • Exploitation of multiƛ/multimessenger
• Phased assembly till ~2028 synergies
The SQUARE KILOMETRE ARRAY SKA Science Working Groups • Cover all science areas that SKA will address • Interaction with astronomical community
