It's a big week for us here at the South Pole as we've begun preparations for this year's Event Horizon Telescope observing run. Recently we installed EHT's secondary and tertiary mirrors on the telescope deck and cooled the receiver "camera" down to just a few degrees above absolute zero. (All in a brisk -100F wind-chill)
