Since the launch AIA has taken over 100 million images, with HMI not that far behind at 80 million. EVE has returned over 12 million EUV spectra of the Sun. There have been many science results, with over 2000 papers so far presenting SDO science results. My favorite observations include the trebuchet eruption, comets in the corona, and the Transit of Venus in 2012.
SDO is a great observatory! How about 5 more years?
