Tested TAL-D55 plasma engine. Also was part of the NRO's ATeX advanced tether experiment, which reportedly failed on January 16. The ATeX lower end mass was meant to remain attached to the STEX parent spacecraft, but with only 21 m of tether deployed, it appeared the tether was so far off vertical that automatic safety systems jettisoned the base to protect the remainder of the STEX satellite. Thus,the upper and lower ATeX end masses were in orbit as one object connected by a 21 m tether, and designated USA 141 (1998-055C). The main STEX satellite was in orbit as a separate object, 1998-055A.
Remained attached to STEX.

Measured the integrated solar energy output from 0.2 to 2 microns. Carried instrument deleted from Terra spacecraft.
Korean Multipurpose Satellite; carried an ocean color sensor developed by TRW and particle detectors. KOMPSAT was built by the Korean Aerospace Research Institute (KARI) based on a test model built by TRW; it used the TRW STEP Lightsat bus and had a mass of around 500 kg, with 73 kg of hydrazine fuel.
Sandia Multispectral Thermal Imager (MTI), aka USAF Space Test Program mission P97-3. The satellite was equipped with a hyperspectral imager for military target recognition / treaty monitoring applications.
