The Transition Region and Coronal Explorer was a NASA Small Explorer (SMEX) mission to image the solar corona and transition region at high angular and temporal resolution. The TRACE project maintains an Open Data Policy: all data are available from our data archives (see below) to the science community. The TRACE mission obtained its last science image on 2010/06/21 23:56 UT.
