Lunar Launch vehicle comparison
In order to have a successful mission to the moon you have to have a powerful and reliable rocket. A lot of research is required to design and launch a vehicle of this caliber. The US already successfully undertaken one program to reach the moon; this program is known to the world as the Apollo programs. In this program the US’s space agency the National Aeronautics and Space Administration (NASA) was responsible for the design and deployment of arguably the most powerful rocket ever built, Saturn V. That was the 1960’s, here in the 2000’s the Apollo program is history and the Saturn V has been retired. There is a new program though that is designed to return US Astronauts to the moon once again and eventually to Mars. This program is called Constellation. The launch vehicle that will do the heavy lifting for this program is the Ares V and the Ares I will launch humans into space. This paper seeks to compare the old lunar launch vehicle to the new lunar launch vehicle and highlight the differences. Saturn Launch Vehicle

History and Development
The history of the Saturn launch vehicle dates back as early as 1950. The Saturn Rocket family was the result of several other rocket research including Jupiter and Redstone Rockets. The Department of Defense at one point expressed interest in a heavy lift rocket to place satellites into orbit. Prior to the launch of Sputnik (Russia), the first man-made Satellite; most of the interest in rockets was military based. After the launch of Sputnik there was a huge government interest in a civilian agency to focus on space exploration. NASA was formed on 28 July 1958. It was then that manned space flight was researched. Early on NASA immediately began researching launch vehicles for a mission to the moon. The Silverstein Committee was created to recommend different launch vehicle configurations for NASA. The Silverstein Committee proposed three different types of Saturn Launch Vehicle configurations. Saturn A, Saturn B, and Saturn C. Saturn A configuration was actually two separate set-ups A-1 and A-2. A-1 consisted of a cluster lower stage, a Titan second stage and a Centaur third stage. While A-2 consisted of a cluster lower stage a proposed Jupiter second stage, proposed S-IV third stage and a Centaur fourth stage. Saturn B recommendation had only one setup B-1. The B-1 setup consisted of a Saturn cluster lower stage, proposed Titan cluster second stage, proposed S-IV third stage, and a Centaur fourth stage. Saturn C was the last recommendation. It included five different configurations: C-1, C-2, C-3, C-4, and C-5. The C-1 configuration consisted of a Saturn cluster lower stage, proposed S-II second stage, and a proposed S-IV third stage. The C-3 thru C-5 stages was based on a new lower stage using F-1 engines, variations of the proposed S-II second stages, and proposed S-IV third stages.

Kennedy challenged NASA and ultimately the US to send man to the Moon and return him safely to Earth. This eventually led to the creation of the Apollo program. It was for this program that the Saturn C configuration of C-5 was chosen....
