During the last 15 years, the US Congress has authorized budgets totaling $46 billion for various NASA deep-space exploration plans. The Ares project, as part of NASA's Constellation Program, would be abandoned the next year, as it was behind schedule and over budget. Later, in 2014, NASA launched an uncrewed version of its Orion spacecraft on a private rocket to an altitude of 400km. The first flight of the new SLS rocket, again with an uncrewed Orion vehicle, may occur in 2021. In 2010, President Obama sought to cancel the Constellation Program, which entailed Orion, the smaller Ares I, and larger Ares V rocket.
