| | ===== Astronaut Boarding ===== |
| | |
| | ''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: |
| | |
| | * Space suit, with a full charge and a full supply of breathing gas |
| | * Map of the launch site (for navigating during the descent) |
| | * 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. |
| | |
| | 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'' and ''SRO'' will 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. |
| | |
| | {{gallery> tutorial:dsa:pos?&120x120&lightbox&3 }} |
| | |
| | ''MINERVA'' should leave at least one open space on their hot bar. |
| | |
| | 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. |
| |
| |
| ===== Polling Stations ===== | ===== Polling Stations ===== |
| |
| 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. | When the above procedures are complete, ''LD'' will poll all flight controllers and request a "go/no-go" for launch decision. |
| |
| The ''LD'' shall poll the following stations, in order: | During polling, each launch controller should give a "go" or "no-go" for launch. Upon giving the "go," |
| |
| - ''MINERVA'' | * Flight controllers will move their hold switch to the down-and-off position. The red light above the switch will extinguish. |
| - ''CGLS'' | * ''MINERVA'' should activate the capsule's flight controls by moving the Pilot's Arm Switch to ''ARM''. Lights on the control console will illuminate. |
| - ''SRO'' | |
| - ''LRD'' | |
| - ''SAFETY'' | |
| - ''TBC'' | |
| - ''CTC'' | |
| - ''LPS'' | |
| - ''LD'' | |
| |
| 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: | 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 ready |
| | - ''SRO'': Range is clear of hazards |
| | - ''LRD'': Ready to retrieve astronaut |
| | - ''SAFETY'': Contingency abort systems are ready |
| | - ''TBC'': Minerva booster has been fueled |
| | - ''CTC'': Minerva capsule has been prepared |
| | - ''LPS'': Astronaut boarding is complete |
| | - ''MINERVA'': In position and ready for launch |
| | - ''LD'': 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: |
| |
| - Provide a pre-count to initiate the countdown on his/her "mark." | - Provide a pre-count to initiate the countdown on his/her "mark." |

| |
| 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). | To resume the countdown, use the green ''GO'' button. The countdown will resume from the last milestone. |
| | |
| | ==== Aborting the Countdown ==== |
| | |
| | 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. |
| | |
| | ==== Launch Commit ==== |
| | |
| | After //launch commit//, no pre-launch abort is possible. Lift-off must continue. Consult the [[#Contingencies]] section. |
| | |
| | ===== Ascent Phase ===== |
| | |
| | At T+ 00:00, the TNT will light. Very shortly thereafter, ''MINERVA'' will cease to be in an inertial frame of reference and become a part of the great Stellar Machinery of the Cosmos. If the astronaut is fortunate, this condition will only be temporary. The launch vehicle's computer will handle spacecraft control during this phase, leaving very little to do. |
| | |
| | After lift-off, ''SAFETY'' must ensure that the Master Power switch remains in the ''ON'' position unless a major contingency occurs. |
| | |
| | At lift-off time, ''MINERVA'' will receive a thrown potion of Parachute. This is an integral part of the Minerva space capsule and will be needed during the descent phase. |
| | |
| | ===== Descent Phase ===== |
| | |
| | <WRAP center round important 60%> |
| | The Minerva space capsule is only certified for **water landings**. Attempting to land on a surface other than water will result in a **loss-of-vehicle** accident. |
| | </WRAP> |
| | |
| | At T+ 01:04, the main engines will cut off. ''MINERVA'' will cease to ascend and, very shortly, will begin to descend. Very rapidly. Astronauts can expect [[http://minecraft.gamepedia.com/Entity#Motion_of_entities|accelerations]] of -32 m/s<sup>2</sup>, with a terminal velocity of 78.4 m/s. Astronauts will, for a time, become the fastest-moving objects in the world. At such speeds, navigating to a safe landing site is all but impossible---the astronaut will need some way to slow down. The Parachute potion will provide the necessary air braking. |
| | |
| | Astronauts should monitor their altimeter during the descent phase. When the absolute altitude reads ''400 meters'' or below, deploy the Parachute by using the potion with the //[Use Item]// command. Dropping the potion is //not// sufficient---it must be //used//. A complicated series of pyrotechnics will prevent the resulting deceleration from having lethal effects. The Parachute may safely be deployed at any altitude. If it is deployed at apogee, however, the astronaut will be in for a long wait. |
| | |
| | The Parachute potion is an integral part of the Minerva launch vehicle. It will not work without the rest of the vehicle. |
| | |
| | Once under parachute, ''MINERVA'' should use the provided map to navigate to the designated landing site. The spacecraft's maneuvering thrusters and aero surfaces use an intuitive control scheme that is rather much like walking. Due to an excess of both kinetic and thermal energy accumulated during the flight, the Minerva spacecraft must land in //deep water//. Failure to steer to safe water will result in a //loss-of-vehicle// accident. |
| | |
| | After splash-down, ''LRD'' is responsible for retrieving the astronaut and returning them back to the SpaceHab for <del>de-briefing</del> a post-flight PARTY. In order to avoid collision with the landing space vehicle, ''LRD'' must remain well clear of the landing site and remain //stationary//. ''LRD'' must not move until after spash-down has occurred---except to avoid an imminent collision. ''MINERVA'' is primarily responsible for maneuvering to avoid collisions. |
| | |
| | At the safe conclusion of the flight, ''SAFETY'' should return the Master Power switch to the ''off / SAFE'' position. |
| | |
| | ===== 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. |
| | |
| | - ''SAFETY'' should return the Master Power switch to the ''off / SAFE'' position. This will abort the countdown. |
| | - Capsule occupant should return the Pilot's Arm Switch to the ''off / SAFE'' position. |
| | - 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. |
| | |
| | ''MINERVA'' should use directional controls to orient themselves to the North, and maneuver to the North with maximum speed. If this is done sufficiently quickly, the spacecraft will fall in the water immediately to the north of the pad. ''LRD'' should retrieve the astronaut. |
| | |
| | ==== 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. |
| | - ''MINERVA'' should deploy the Parachute potion immediately. Deploying the Parachute potion will also cut off the main engines. |
| | - 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 [[#Alternate Landing Site]]. |
| | |
| | ==== Engines Out ==== |
| | |
| | If the launch vehicle's engines fail during the ascent phase, ''MINERVA'' should deploy the Parachute potion immediately. Follow the procedure under [[#Early Ascent Abort]]. |
| | |
| | ==== 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 ''MINERVA.'' Use the provided map as an aid. Ideal landing sites are discussed in [[#Landing Site Selection]]. Be sure to avoid the immediate area of the tower, which is a tall obstacle. Inform ''LD'' of your decision. Astronauts should use their provided survival life raft for emergency flotation. |
| | |
| | ==== Parachute Non-Deployment ==== |
| | |
| | In the event of parachute non-deployment, don't panic. Landing may still be survivable. The spacecraft will have much less time to maneuver, and the astronaut will have much less control over the descent. Use the provided map to select an [[#Alternate Landing Site]] that is nearly directly below ''MINERVA'''s present position. Once this has been done, prepare for the Ultimate Water Wedgie. |
| |
| 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, ''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. | 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]] or [[Aransas]]. If this event occurs, it is the sole responsibility of ''SAFETY'' protect innocent lives on the ground by discontinuing to the flight. |
| |
| | - ''SAFETY'' should move the Master Power switch to the ''Off / SAFE'' position. This will abort the flight. |
| | - The astronaut should perform an emergency egress procedure to leave their falling space capsule. The vehicle's systems will be shut down, and the Parachute will be inoperative. Follow procedure under [[#Parachute Non-Deployment]]. |
