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. Errant boaters need to be kept out of the blast hazard areas. It is the responsibility of SRO to ensure that nothing threatens, or is threatened by, the launch.
At the beginning of active operations, SRO will travel to the pad by boat and conduct a range survey. Any abnormalities should be reported and corrected. SRO will remain at or near the pad until boarding is complete, monitoring the area for hazards.
Although the SRO is responsible for the range as a whole, the LRD is responsible for the selection and maintenance of a safe landing site. Landing sites must be in a large body of water which is at least three meters deep throughout. Landing sites must be free of debris and tall obstructions in any direction. Care should be taken that there are no shallow areas.
When descending under parachute, the Minerva space capsule has the following flight characteristics
| Sink rate | 8.7 m/s |
|---|---|
| Glide ratio (horz:vert) | 1:2.1 |
| Preferred parachute deployment altitude | 400 m |
Given these characteristics, landing sites should be within about 160 meters of the pad—but are frequently much closer. Assuming that the spacecraft ascends straight up, calculate the deployment altitude and direction of travel after deployment which will bring the capsule back to the landing site. Leave plenty of margin. This information should be communicated to the mission planners and MINERVA.
Before fueling begins, SAFETY will ensure that the controls in the Launch Control Center (LCC) are correctly set in the safe position. SAFETY must check that:
off / SAFE.REDRED
The master power switch must remain off for the duration of fueling. SAFETY should also toggle all flight controller hold switches to the hold position. When the switches are in the hold position, the status torches above each workstation will illuminate red.
Fueling the launch vehicle is a high-risk activity. Read carefully.
CTC and TBC are responsible for fueling the launch vehicle. Because this is a high-risk activity, they will check each others' work. Once SAFETY and SRO have given the go-ahead, fueling may commence.
TBC will craft a total of twelve (12) units of TNT.CTC and TBC will verify that the beacon at the launch pad is RED, then proceed to the launch pad.CTC will ascend the launch pad and enter the capsule. CTC will verifySAFE position. Lamps on the capsule's control station will be extinguished; ANDTBC is clear to begin loading. TBC will access the launch vehicle's fueling door. The fueling door is located on Swing Arm #2, which is the second of the four swing arms up the tower. The fueling door may be opened with a lever.TBC will climb to the top of each ladder in turn. Beware of live wires.TBC must load one (1) unit of TNT into each dispenserTBC has completed fueling the dispensers, CTC will check that each of the twelve dispensers has exactly one unit of TNT loaded into it. No other items should be placed into dispensers!CTC and TBC will leave the interior of the launch vehicle. TBC will close the fuel door, and CTC will check that it has been closed.
CTC and TBC should return to the Launch Control Center when fueling is complete.
LPS is responsible for ensuring that MINERVA is ready to depart on schedule. Prior to departure, the astronaut should report to the Suit Checkout room in the basement of the SpaceHab. LPS will ensure that MINERVA has, or is furnished with, the following Minimum Equipment List:
Other equipment—especially items of high monetary of sentimental value—should be left behind. Unneeded equipment may be kept in the astronaut lodging accommodations.
At the scheduled departure time, LPS and MINERVA will depart via the SpaceHab harbor. There will be a brief press appearance at this time. After fueling operations have concluded, SRO will grant permission to approach the launch pad. LPS and MINERVA will then depart for the launch pad. Concurrently, LRD should proceed by boat to the designated landing site.
Once the astronaut has boarded the space capsule, LPS will close the Minerva capsule's hatch. LPS and SRO will then clear the launch pad.
MINERVA should assume the launch position, as practiced. The astronaut must stand on the yellow carpet, use the [crouch] key, and move as close to the TNT Reactor Pool as possible. The astronaut must remain away from the walls of the spacecraft and stay on the yellow carpet only. See the reference photos below.
It is the responsibility of SRO to ensure that all personnel, with the exception of astronauts, are safely away from the pad. SRO should continue to observe the range from the roof of the LCC. Once these procedures are complete, the Minerva spacecraft is ready for launch.
When the above procedures are complete, LD will poll all flight controllers and request a “go/no-go” for launch decision.
During polling, each launch controller should give a “go” or “no-go” for launch. Upon giving the “go,”
MINERVA should activate the capsule's flight controls by moving the Pilot's Arm Switch to ARM. Lights on the control console will illuminate.If the controller is not physically present in the control room—i.e., they are occupied elsewhere—then an adjacent controller will operate their lever.
The LD shall poll the following stations, in order. The primary go/no-go criteria is as follows:
CGLS: Launch computers are readySRO: Range is clear of hazardsLRD: Ready to retrieve astronautSAFETY: Contingency abort systems are ready TBC: Minerva booster has been fueledCTC: Minerva capsule has been preparedLPS: Astronaut boarding is completeMINERVA: In position and ready for launchLD: Controllers have followed procedures
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.
To resume the countdown, use the green GO button. The countdown will resume from the last milestone.
After main engine start, at T- 00:19 seconds, all holds will be considered an 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).
MINERVA may abort the launch by rotating the Pilot's Arm Switch to the down-and-off position. This action will not hold the countdown, but it will prevent TNT ignition. In the event that MINERVA requests a countdown hold, CGLS is responsible for holding the countdown.
After launch commit, no pre-launch abort is possible. Lift-off must continue. Consult the Contingencies section.
This section list various emergency / contingency procedures.
