Re-entry is expected late this month or early October. The teleconference participants are: -- Paul Hertz, chief scientist, NASA's Science Mission Directorate, Washington -- Nick Johnson, chief scientist, NASA's Orbital Debris Program, Johnson Space Center, Houston -- U.S. Air Force Maj.

UARS was launched Sept. 12, 1991, aboard space shuttle mission STS-48 and deployed on Sept. 15, 1991. It was the first multi-instrumented satellite to observe numerous chemical components of the atmosphere for better understanding of photochemistry. UARS data marked the beginning of many long-term records for key chemicals in the atmosphere. The satellite also provided key data on the amount of light that comes from the sun at ultraviolet and visible wavelengths. UARS ceased its productive scientific life in 2005.
