TRACE Chronology

02 April 1998 TRACE Program: Small Explorer. Launch Site: Vandenberg . Launch Vehicle: Pegasus XL. Perigee: 602 km. Apogee: 652 km. Inclination: 97.8 deg.

NASA's third Small Explorer, the Transition Region and Coronal Explorer (TRACE), was successfully launched by an Orbital Pegasus XL. The L-1011 carrier aircraft took off from Vandenberg and dropped the Pegasus over the Pacific Ocean. TRACE, a project led by Lockheed's solar physics group, carried a 30-cm extreme ultraviolet imaging telescope which will study the Sun.
