Why do times vary so greatly with rocket launches? Well, there are several factors that scientists and engineers take into account to determine the rocket launch window. The final destination is what drives many of the conditions for the launch. The orbit the rocket needs to reach, dictates the time the launch needs to happen.
The goal of any launch is to minimize the propulsion needed to get the rocket or the payload to its destination. Seconds could mean the difference between reaching a target or a complete mission failure. The launch pads at Cape Canaveral, FL help NASA and leaders like SpaceX take advantage of the turning of Earth.Rockets launched eastward from the Cape can gain over 900 mph because of the boost from Earth’s natural spin. Earth spins from west-to-east, meaning any object heading in the same direction will gain some velocity. So, being close to the equator helps experts take advantage of Earth’s added natural propulsion. The open Atlantic Ocean, to the east of the Cape doesn’t hurt either. It provides area vast area to ditch the rocket, during any emergency.
