STEP 3 [TRW]
STEP 3 (Space Test Experiment Platform 3) was an experimental satellite launched for the Space Test Program (STP).
Prime contractor for the mission was TRW. The spacecraft was 3-axis stabilized and based on CTA's LEOStar bus.
STEP 3 featured following experiments for DoD:
- ACTEX (Advanced Controls technology experiments),
- EDMM (erasable disk mass memory),
- SAMMES (space active modular experiment),
- SAWAFE (strategic attack warning & assessment flight experiment),
- SQUOD (space qualified optical disk)
STEP 3 was lost in an launch failure of the air launched Pegasus-XL rocket.
