Our launch would contain four stages for maximum speed and acceleration into the solar system to establish a high drifting velocity out of the solar system and on the way to our exoplanet. The first three stages are designed to break Earth’s gravitational pull, each section breaking off of the rocket into the atmosphere (or space) once the fuel contained is completely burned through. This stage of the launch is by far the shortest, lasting under an hour.
The figure below describes the Delta IV heavy payload rocket comparisons:
The newest rocket engines, such as the Rocketdyne J-2X, on the market today burn liquid oxygen and liquid hydrogen in a 5.5 mix ratio for fuel and can produce 1,300kN of force, burning for over 7 minutes. However, the further away the mission destination is, the same amount of boost from the rockets stages must carry a smaller payload to compensate for the distance. These newer engines, equipped in the first Earth Departure Stage and the second stage of launch, can carry a payload of 200,000kg to Low Earth Orbit, equivalent to carrying 80,000kg on a mission to the Moon, or 1.5kg to outer orbits and beyond the solar system.
