The basic details of the bill have been known for some time now, but President Obama has only just today signed the NASA Authorization Act of 2010 into law, which allocates $19 billion in funding for the space agency and signals a shift to commercial spacecraft for transporting astronauts to the International Space Station. NASA
will hardly be relying on private spacecraft altogether, however, as the bill also gives NASA the go-ahead to develop a heavy lift rocket for deep space exploration (possibly to launch by the end of 2016), and it gives NASA a mandate to continue operating the International Space Station itself until 2020 -- not to mention fly one additional shuttle mission to it next year. Curious to know every last detail? You can find the complete 42-page bill at the source link below.
