The Transition Region and Coronal Explorer is a NASA Small Explorer (SMEX) mission to image the solar corona and transition region at high angular and temporal resolution. The 30 cm aperture TRACE telescope uses four normal-incidence coatings for the EUV and UV on quadrants of the primary and secondary mirrors. The segmented coatings on solid mirrors form identically sized and perfectly coaligned images. Pointing is internally stabilized to 0.1 arc second against spacecraft jitter. A 1024 x 1024 CCD detector collects images over an 8.5 x 8.5 arc minute field-of-view (FOV). A powerful data handling computer enables very flexible use of the CCD array including adaptive target selection, data compression, and fast operation for a limited FOV. TRACE explores the magnetic field in the solar atmosphere by studying: • the 3-dimensional field structure • its temporal evolution in response to photospheric flows • the time-dependent coronal fine structure • the coronal and transition region thermal topology. TRACE pass-bands are: White Light, Lyman Alpha, C IV 1550, UV Continua and imaging in 173A, 195, and 284
