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
.RED
RED
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. 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.
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. The primary go/no-go criteria is as follows:
MINERVA
: Ready for launchCGLS
: 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 completeLD
: 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.
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.
