More on TRACE from NASA:

TRACE was the first mission to image an entire cycle of solar activity, studying the sun at both its turbulent maximum and demure minimum. The satellite observed some fine-scale structures for the first time as well, including coronal or solar moss, a sponge-like structure found at the base of some coronal loops. On June 21, 2010, TRACE took its last image, after millions of images taken before the last and 12 successful years in orbit.
