DSA Launch Procedure
Polling Stations
Each launch controller should give a “go” or “no-go” for launch. Upon giving the “go,” the corresponding hold switch should be moved to the down and off position. The red light above the switch will extinguish.
| Controller | |
|---|---|
| Abbr | Title |
| CGLS | Ground launch sequencer engineer |
| SRO | Superintendant of range operations |
| LRD | Landing and recovery director |
| SAFETY | Safety console coordinator |
| TBC | Tank/booster test conductor |
| CTC | Capsule test conductor |
| LPS | Launch processing system coordinator |
| LD | Launch director |
If all flight controllers are “go” and no red lights are visible above the controller desks, then the Launch Director should
- Provide a pre-count to initiate the countdown on his/her “mark.”
- Press the green “GO” button to initiate the countdown.
Countdown Events
When reading the countdown aloud, read entries as lights are extinguished. For example, read entry #14 immediately after the first lamp is extinguished.

|---|---|---|
| 15 | T- 01:50 | Countdown initiated |
