"NASA Administrator Charles Bolden sent a letter to Congress Wednesday, Aug. 5, 2015 informing members that, due to continued reductions in the president's funding requests for the agency's Commercial Crew Program over the past several years, NASA was forced to extend its existing contract with the Russian Federal Space Agency (Roscosmos) to transport American astronauts to the International Space Station. This contract modification is valued at about $490 million dollars. The letter was delivered to the leadership of the congressional committees that oversee NASA. The full text of the letter follows:"
NASA signing $490M contract with Russia, The Hill
"The new contract extension is required because Congress has not fully funded the administration's budget requests since 2010. For fiscal year 2011, for example, Obama asked Congress for $500 million for NASA's Commercial Crew Program. Congress only gave it $321 million. The next year, Obama asked for $850 million and Congress only allocated $400 million. Due to those low funding levels for five consecutive years, NASA had to ask Congress for more than $1 billion for next year. A spokeswoman for NASA said if Obama's request is fully funded, and if NASA can fully pay its contracts, the U.S. commercial vehicles could still be ready by the 2017 date."
