New generation rockets

The NASA aims at replacing its old space shuttle by Ares I which is developed to carry an Orion crew capsule near the Earth orbit where as Ares V to carry a rocket and Lunar Lander. But in Ares I there are some technical difficulties found even though it has been developed for a decade by investing tens of billions of extra dollars. Therefore representatives of NASA have been asked the White House to recommend for a future space craft and mission options for them. From then the group of rebel NASA engineers as well as several aerospace companies pushing their own models and commercially built rockets. Even though all rockets have enough power to take a crew capsule to the international space station that resides in the low-Earth orbit, only a few can handle difficult and co-operative situations in their distant missions. NASA's current plan involves developing Ares I and its companion Ares V.
