STEX's (Space Technology EXperiments) main equipment was provided by the Naval Research Laboratory. These included:
- Hall Effect electric thrusters derived from Russian technology
- Experimental solar arrays and batteries
- ATEX advanced tether experiment, a follow-on to the earlier TIPS satellite. This comprised two end masses connected by a 6 kilometre polyethelyne tether. The upper end mass was deployed first, while the lower end mass remained attached to STEX. After a series of dynamics experiments in this configuration, the lower end mass was separated from STEX and the ATEX became a free-flying pair subsatellite.
