Many individuals contribute to the safe and successful launch of DSA Spacecraft. The official job titles and descriptions of each participant are listed below. If there is a shortage of manpower, one person can assume several roles.
| Station | |
|---|---|
| Abbr | Title |
LPS | Launch processing system coordinator |
SURGEON | Flight surgeon |
SRO | Superintendant of range operations |
SAFETY | Safety console coordinator |
CTC | Capsule test conductor |
TBC | Tank/booster test conductor |
CGLS | Ground launch sequencer engineer |
LRD | Landing and recovery director |
LD | Launch director |
MINERVA | Spacecraft pilot |

One to two days before launch, astronauts should report to the SpaceHab for astronaut training. LPS is responsible for conducting the training. The Quarantine Area houses a complete mock-up of the Minerva space capsule. Astronauts will learn:
The DSA requires that all astronauts be in top physical condition prior to departure. SURGEON will administer a complete physical and ensure that the astronaut is current on all their immunizations.
At the conclusion of training, the astronaut will name their spacecraft. This is how controllers will address the spacecraft during the flight.
The next step to a successful launch is a range survey. Although the DSA's missile range is built in a remote, unpopulated area, wildlife may still pose a threat.
During polling, 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. If the controller is not physically present in the control room—i.e., they are occupied elsewhere—then an adjacent controller will operate the lever.
The LD shall poll the following stations, in order:
MINERVACGLSSROLRDSAFETYTBCCTCLPSLD
If all flight controllers are “go” and no red lights are visible above the controller desks, then LD should request that CGLS commence the countdown. CGLS will then:
CGLS should read the countdown aloud. When reading the countdown, read the times and milestones from the following table. Both should be read as lights are extinguished. For example, read entry for “Ground launch sequence start” immediately after the first lamp is extinguished.
| Lamps Lit | T± (MM:SS) | Milestone |
|---|---|---|
| 15 | T- 01:50 | Countdown initiated |
| 14 | T- 01:43 | Ground launch sequence start |
| 13 | T- 01:36 | |
| 12 | T- 01:29 | |
| 11 | T- 01:22 | |
| 10 | T- 01:15 | Main engine gimbal test |
| 9 | T- 01:08 | |
| 8 | T- 01:01 | |
| 7 | T- 00:54 | Internal power transfer |
| 6 | T- 00:47 | |
| 5 | T- 00:40 | |
| 4 | T- 00:33 | Auto-sequence start |
| 3 | T- 00:26 | |
| 2 | T- 00:19 | Main engine start |
| 1 | T- 00:12 | |
| 0 | T- 00:05 | Launch commit |
| – | T+ 00:00 | TNT Ignition |
| – | T+ 00:04 | Lift-off |
| – | T+ 01:04 | Main engine cut-off |
At any time prior to main engine start, at T- 00:19 seconds, any controller may request that the countdown be held by
CGLS should acknowledge that the countdown has been held.
After main engine start, all holds will be considered a mission ABORT. To re-start from an abort condition, the master power must be cycled off, then back on again, and the full countdown must be started from the top (i.e., T- 01:50).
After launch commit, no abort is possible, and the flight must continue.
In the event of a hold or abort, MINERVA should rotate the Pilot's Arm Switch to the down-and-off position. This action will inhibit and prevent TNT ignition, but it will not hold the countdown. In the event that MINERVA requests a countdown hold, CGLS is responsible for holding the countdown.
