The sq. Kilometre Array (SKA) venture is a world undertaking to layout and c- struct a progressive new radio telescope with of order 1 million sq. meters of gathering quarter within the wavelength diversity from3mto1cm.It could have - ders of importance larger sensitivity than present telescopes and an unparalleled huge prompt ?eld-of-view. those functions will make sure the SKA will play a number one position in fixing the main astrophysical and cosmological questions of the day (see the technological know-how case at www.skatelescope.org/pages/page astronom.htm). The SKA will supplement significant floor- and space-based astronomical amenities less than development or deliberate in different elements of the electromagnetic spectrum (e.g. ALMA, JWST, ELT, XEUS,...). the present agenda for the SKA foresees a call at the SKA web site in 2006, a decisiononthedesignconceptin2009,constructionofthe?rstphase(international path?nder)from2010to2013,andconstructionofthefullarrayfrom2014to2020. the price is envisioned to be approximately one thousand M . TheSKAProjectcurrentlyinvolves45institutesin17countries,manyofwhich are all in favour of nationally- or regionally-funded state of the art technical devel- ments being pursued prior to the 2009 collection of layout proposal. This precise factor of Experimental Astronomy offers a picture of SKA engineering act- ity world wide, and is predicated on shows made on the SKA assembly in Penticton,BC,CanadainJuly2004.Topicscoveredincludeantennaconcepts,so- ware, sign shipping and processing, radio frequency interference mitigation, and experiences on similar applied sciences in different radio telescopes now below development. additional details at the venture are available at www.skatelescope.org.
