======Pre-Launch======
The **Pre-Launch** phase is a very long process which can take even months of preparations. Most of them are done in the VAB (Vehicle Assembly Building). The part we are interested in - and the earliest time any SSM2007 mission starts - happens from the approximate time when the Astronauts enter the Shuttle at T-01:50:00.
