DSP-21

 2001-033A

---

DSP-21 launched by Titan 4B-31 with the IUS-16 upper stage. Shortly afterwards, DSP 17 vacated the 103E position and was replaced by DSP 18 which moved there from the 70E position; it seems a reasonable assumption that DSP 21 occupied the prime 70E Indian Ocean position.

DSP 21 carried a sensor to detect space weather related anomalies.
