The main science goal of our experiment is to measure faint microwave signals to help us better understand the Big Bang. Because the signals are so faint (equivalent to temperature fluctuations of less than 0.000001 degrees), we need incredibly sensitive detectors to find them. Furthermore, there are lots of stronger signals (e.g. from our own Galaxy) we have to reject in order to see the tiny ones from the beginning of the Universe. Therefore, most of our work here comes in two parts: upgrading our telescopes and characterizing how they respond to different types of signals.
