The National Aeronautics and Space Administration Authorization Act of 2010 bill is expected to be signed by President Obama Monday.
The bill passed by Congress last week, and the billions of dollars in it include money for commercial space programs, the authorization for NASA to develop a heavy lift vehicle that would fly beyond lower earth orbit and the go ahead for NASA to add a shuttle launch.
This would be the very last lift-off of the space shuttle program. The federal dollars, including the cost of the additional launch, has not yet been appropriated. If the extra launch is a go it would likely take place in June 2011.
The two remaining "scheduled" shuttle missions will fly from Kennedy Space Center in Florida on the following days:
November 1st, 2010
Space Shuttle Discovery
4:33 p.m. EDT
February 26, 2011
Space Shuttle Endeavour
4:04 p.m. EDT
