Originally legislated by the NASA Authorization Act of 2005, as the retirement of the Space Shuttle drew near, the Constellation program included the development of the Ares I and Ares V rockets along with the Orion spacecraft.[21] In May 2009, U.S. president Barack Obama established the Augustine Committee to take into account several objectives including support for the International Space Station, development of missions beyond low Earth orbit (including the Moon, Mars, and near-Earth objects), and use of the commercial space industry within defined budget limits.[22] The committee concluded that the Constellation program was massively underfunded and that a 2020 Moon landing was impossible. Constellation was subsequently put on hold.[23]

On April 15, 2010, President Obama spoke at the Kennedy Space Center, announcing the administration's plans for NASA and cancelling the non-Orion elements of Constellation, saying that the program was not viable.[24] He instead proposed US$6 billion in additional funding and called for the development of a new heavy-lift rocket program to be ready for construction by 2015 with crewed missions to Mars orbit by the mid-2030s.[25]

On October 11, 2010, President Obama signed into law the NASA Authorization Act of 2010, which included requirements for the immediate development of the SLS rocket and the Orion spacecraft to support missions beyond low Earth orbit starting in 2016, while making use of the workforce, assets, and capabilities of the Space Shuttle program, Constellation program, and other NASA programs. The law also invested in space technologies and robotics capabilities tied to the overall space exploration framework, ensured continued support for Commercial Orbital Transportation Services, Commercial Resupply Services, and expanded the Commercial Crew Development program.[26]

On June 30, 2017, President Donald Trump signed an executive order to re-establish the National Space Council, chaired by Vice President Mike Pence. The administration's first budget request kept Obama-era human spaceflight programs in place: Commercial Resupply Services, Commercial Crew Development, the Space Launch System, and the Orion spacecraft for deep space missions, while reducing Earth science research and calling for the elimination of NASA's education office.[27]

(Ignoring the comedy of errors and delays that preceded the rocket getting rolled out onto that pad)
