Parameters: HAB fuel load @ MES = 25000 kg
:::intercept target’s orbital altitude = 315 km
:::HAB intended orbital altitude = 350 km (so we end up above the target)

Abreviations: MES = main engine start
:::MECO = main engine cut-off
:::SRBI = solid rocket booster ignition
:::MET = mission elapsed time
:::Qmax = point of maximum dynamic atmospheric pressure indicated
:::::by top readout in second display box on orbit software

Plan: The spacecraft is vulnerable to re-entry in the case of engine failure until orbital Vtan is reached.
Launch to orbit profile is designed to minimize the time taken to reach ref Vo orbital speed. Initial vertical launch
takes the spacecraft out of the thick part of the atmosphere as rapidly as possible to minimize fuel use and time to
reach orbital speed. Roll to ccw prog orientation is initiated at a point such that when ccw prog orientation is reached,
the spacecraft has the necessary vertical velocity to coast up to the desired orbital altitude while the engines are used
only to accelerate the spacecraft to the necessary Vtan as rapidly as possible. If the procedure is followed, the
spacecraft should reach the desired maximum orbital altitude (Vcen = 0) at the same time as Vtan reached the required
value to maintain a circular orbit at that altitude. This minimizes the time taken to circularize the orbit after final
MECO. With the correct angular separation from the target at liftoff, the spacecraft should reach the top of its orbit
and complete circularization just as the target pulls along side.

===Procedure===
GUIDO confirms time that target reaches angle for spacecraft liftoff using ORBIT5tm.
This time is communicated to FIDO who ensures that it is loaded into ORBIT5sd as the mission start time (MST).
