NASA. Solar observation carried out by the TRACE (Transition - Lot 232

NASA. Solar observation carried out by the TRACE (Transition Region and Coronal Explorer) program. TRACE was a NASA solar and heliophysical observatory designed to study the links between small-scale magnetic fields and associated plasma structures on the Sun by providing high-resolution images and observations of the solar photosphere, transition region and corona. The TRACE instrument focuses primarily on the fine structure of low-level coronal loops in the solar atmosphere. TRACE is the third spacecraft in the Small Explorer program, launched on April 2, 1998, and obtained its last scientific image on June 21, 2010. Vintage chromogenic print. Numbering in the margin on the front. Legend on label on back. 25.4 X 20.4CM with margins.
