# A NINTH DEGREE POLYNOMIAL APPROXIMATION WHICH IS VALID OVER A 15
# DAY INTERVAL BEGINNING SHORTLY BEFORE LAUNCH. THEREFORE THE TIME
# INPUT BY THE USER SHOULD FALL WITHIN THIS 15 DAY INTERVAL.
## The 9th-degree polynomial spoken of here is a pad load, meaning
## that it is not actually hardcoded into the software. Additional
## information about calculating the polynomial can be found on the
