Coronal loops are very important to our understanding of the current "coronal heating problem". Coronal loops are highly radiating sources of plasma and are therefore easy to observe by instruments such as "TRACE". An explanation of the coronal heating problem remains as these structures are being observed remotely, where many ambiguities are present (i.e., radiation contributions along the LOS). "In-situ" measurements are required before a definitive answer can be determined, but due to the high plasma temperatures in the corona, "in-situ" measurements are, at present, impossible. The next mission of the NASA Parker Solar Probe will approach the Sun very closely, allowing more direct observations.
