Space Exploration Act of 2003

H.R. 3057, the Space Exploration Act of 2003, would have directed NASA to establish a long-term timeline for human space exploration beyond Earth's orbit. The bill proposed specific milestones over a 20-year period, including developing reusable vehicles to reach the Moon, asteroids, and eventually Mars, where it aimed to establish human-tended facilities.

For the average citizen, this legislation was designed to transition NASA from short-term missions to a structured, multi-decade roadmap for deep-space travel. By requiring competitive bidding for mission concepts and independent merit reviews, the bill sought to ensure that taxpayer-funded space projects were both innovative and cost-effective. Although the bill was introduced in 2003 and referred to a subcommittee, it did not become law; however, its focus on reusable technology and lunar-to-Mars exploration mirrors many of the goals found in current space programs.
