SKA site final decision ! Not.

April 4, 2012

So as promised, the SKA Members met today (in Schiphol airport, lucky them) to review the recommendation made by the evaluation committee. You can read the announcement here. The decision is ….. we are going to think about it some more !!!

Just remember, it will be very groovy when it all happens. Two things that knocked me out at NAM, SKA-wise. First, Michael Kraemer, discussing the power requirement for cooling the SKA megacomputers, said that perhaps it doesn’t need its own nuclear power plant after all. Seeing as both potential sites are sunny deserts, what we need is a vast solar power array… and this exactly what these remote areas need anyway, and they can sell power back. So there ya go. Not only did radio astronomy apparently invent wifi, but they are going to save the world too. Hows that for impact.

Knockout fact number two. I went to the session with results from LOFAR, the SKA pathfinder. As you may know, it can act as a cosmic ray telescope, detecting radio waves from the air shower made by a particle hitting the top of the atmosphere. The shower arrives at an angle, so a kind of front moves across the array. LOFAR has nano-second time resolution and each station is a hundred metres across or something like that; so they watch the front move across the array. Holy shit, they can WATCH LIGHT MOVING.
