TRACE


American solar satellite. One launch, 1998.04.02. TRACE, carried a 30-cm extreme ultraviolet imaging telescope for studies of the sun. Lockheed was the lead contractor while the Smithsonian Astrophysical Observatory made the telescope mirrors.

TRACE had a field of view of 8.5 arcmin and a resolution of 1 arcsecond. TRACE was placed in a sun-synchronous orbit, enabling it to make continuous observation of the sun.

First Launch: 1998.04.02.
Number: 1 .

1998 April 2 - . 02:42 GMT - . Launch Site: Point Arguello WADZ. Launch Pad: 36.0 N x 123.0 W. Launch Platform: L-1011. LV Family: Pegasus. Launch Vehicle: Pegasus XL. LV Configuration: Pegasus XL F21.
  • TRACE - . Nation: USA. Agency: NASA Greenbelt. Program: Small Explorer. Class: Astronomy. Type: Solar astronomy satellite. Spacecraft: TRACE. USAF Sat Cat: 25280 . COSPAR: 1998-020A. Apogee: 652 km (405 mi). Perigee: 602 km (374 mi). Inclination: 97.8000 deg. Period: 97.10 min. 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. The telescope mirrors were made by the Smithsonian Astrophysical Observatory. TRACE had an 8.5 arcmin field of view and 1 arcsecond resolution.
