Overview of constellation plan

Constellation is a space exploration program terminated by NASA. The whole plan will include a series of new spacecraft, launch vehicles and related hardware, which will be used for various space missions, including the supply and transportation of the International Space Station and landing on the moon. The hardware used in most constellation plans will be based on the space shuttle model, although the core component Orion spacecraft (once called Crew Exploration Vehicle (CLV)) is greatly influenced by Apollo spacecraft and uses crew/service module system. 20 10. 1.29, the white house confirmed that "the constellation plan (returning to the moon) has died" due to the financial constraints in the Obama administration's 20 1 1 budget.
