What is the constellation plan?

Constellation plan is a space exploration plan formulated 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. Although NASA has long claimed that the first launch time of Orion spacecraft was 2065438+March 2005, the actual scheduled time was 2065438+September 2003, and it had to be postponed to 2065433. On 20 10. 1.29, the white house confirmed that "the constellation project (returning to the moon) has died due to the financial constraints in the Obama administration's 20 1 1 budget."
