TRACE
type: Concept
definition: The Transition Region and Coronal Explorer (TRACE) is a NASA Small Explorer (SMEX) mission to image the solar corona and transition region at high angular and temporal resolution. TRACE was launched on a Pegasus launch vehicle from Vandenberg Air Force Base in April 1998. The launch was scheduled to allow joint observations with SOHO during the rising phase of the solar cycle to sunspot maximum. No transition region or coronal imager has witnessed the onset and rise of a solar cycle.
