+ | ===== Astronaut Training ===== | ||
+ | |||
+ | One to two days before launch, astronauts should report to the SpaceHab for astronaut training. '' | ||
+ | |||
+ | * The correct position for launch | ||
+ | * How to use the Pilot' | ||
+ | * How to receive and deploy the Parachute | ||
+ | * How to navigate to a safe landing | ||
+ | |||
+ | The DSA requires that all astronauts be in top physical condition prior to departure. '' | ||
+ | |||
+ | At the conclusion of training, the astronaut will name their spacecraft. This is how controllers will address the spacecraft during the flight. | ||
+ | |||
+ | ===== Range Survey ===== | ||
+ | |||
+ | 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 '' | ||
+ | |||
+ | At the beginning of active operations, '' | ||
+ | |||
+ | ===== Landing Site Selection ===== | ||
+ | |||
+ | Although the '' | ||
+ | |||
+ | When descending under parachute, the Minerva space capsule has the following flight characteristics | ||
+ | |||
+ | ^ Sink rate|8.7 m/s | | ||
+ | ^ Glide ratio (horz: | ||
+ | ^ Preferred parachute deployment altitude|400 m | | ||
+ | |||
+ | Given these characteristics, | ||
+ | |||
+ | ===== Control Safety Check ===== | ||
+ | |||
+ | Before fueling begins, '' | ||
+ | |||
+ | * The master power switch is '' | ||
+ | * The light above the master power switch is not illuminated. | ||
+ | * The countdown status indicator in the LCC is '' | ||
+ | * The beacon at the launch pad is '' | ||
+ | |||
+ | The master power switch must remain off for the duration of fueling. '' | ||

+ | ===== Fueling ===== | ||
+ | |||
+ | <WRAP center round important 60%> | ||
+ | Fueling the launch vehicle is a high-risk activity. Read carefully. | ||
+ | </ | ||

+ | '' | ||

+ | - '' | ||
+ | - '' | ||
+ | - that the Pilot' | ||
+ | - that the capsule compression piston is retracted. When looking down at the dispensers, a vertical stack of **three** dispensers should be visible. **If only one ring of dispensers is visible, halt the process at once!** | ||
+ | - Once these checks are complete, '' | ||
+ | - The interior of the launch vehicle has two ladders. Each ladder leads to its own set of TNT dispensers. '' | ||
+ | - At the top of each ladder is a small alcove in which to stand. **Six** dispensers are accessible from each ladder. | ||

+ | * Life raft | ||
+ | * Rations | ||
+ | * Pickax (for emergency egress) | ||
+ | * Flares | ||
+ | |||
+ | Other equipment---especially items of high monetary of sentimental value---should be left behind. Unneeded equipment may be kept in the astronaut lodging accommodations. | ||

+ | |||
+ | ===== Contingencies ===== | ||
+ | |||
+ | This section list various emergency / contingency procedures. | ||
+ | |||
+ | ==== Launch Pad Fire ==== | ||
+ | |||
+ | If a launch pad fire occurs **prior** to launch, then the launch vehicle and immediate area must be evacuated. | ||
+ | |||
+ | - '' | ||
+ | - Capsule occupant should return the Pilot' | ||
+ | - Personnel at or near the launch pad should evacuate by jumping into the water. | ||
+ | * Personnel near the bottom of the tower should proceed down the tower stairs. | ||
+ | * Personnel near the top of the tower should use the evacuation slide. Red-and-yellow checkered carpet leads the way to the slides. To use the slide, board the minecart and press either of the two adjacent buttons. You may also jump from the slide. | ||
+ | |||
+ | If a pad fire occurs after launch, attempt to continue the mission. | ||
+ | |||
+ | ==== Failure to Clear Tower ==== | ||
+ | |||
+ | If a malfunction occurs shortly after lift-off, the spacecraft may fail to clear the tower. If this occurs, the spacecraft will begin to fall rather than ascend. This is a life-threatening emergency that requires quick response. | ||
+ | |||
+ | '' | ||
+ | |||
+ | ==== Early Ascent Abort ==== | ||
+ | |||
+ | If an abort is desired during the early ascent phase: | ||
+ | |||
+ | - Any flight controller may move their Countdown Hold switch to the on-and-lit position. This will cut off the main engines within approximately five seconds. | ||
+ | - '' | ||
+ | - It is unlikely that the spacecraft will have sufficient energy to reach the planned landing site. If the spacecraft cannot reach the planned landing site, follow the procedure under [[# | ||
+ | |||
+ | ==== Engines Out ==== | ||
+ | |||
+ | If the launch vehicle' | ||
+ | |||
+ | ==== Alternate Landing Site ==== | ||
+ | |||
+ | If, for any reason, the descending spacecraft is unable to reach the planned, primary landing site, a new site must be selected. Site selection is entirely at the discretion of '' | ||
+ | |||
+ | ==== Parachute Non-Deployment ==== | ||
+ | |||
+ | In the event of parachute non-deployment, | ||
- | After //launch commit//, no abort is possible, and the flight must continue. | + | ==== Launch Vehicle Threatens Populated Area ==== |
- | In the event of a hold or abort, '' | + | The Minerva Launch Vehicle may experience a malfunction which results in an early-flight course deviation. These deviations may place the vehicle on a path where it may impact nearby inhabited areas, such as [[Trigepelago]] |
+ | - '' | ||
