"Russia has signed a contract with the United States to deliver six NASA astronauts aboard Russian-made Soyuz MS spacecraft to the International Space Station (ISS) in 2018-2019, according to a quarterly report released by Energiya Rocket and Space Corporation on Monday. Energiya Corporation is the producer of Russian spacecraft. According to the document, NASA will pay Russia 5.7 billion rubles ($88 million) for the delivery of NASA astronauts to the ISS and their return to the Earth. The deal was signed on January 27."
Boeing's first crewed Starliner launch slips to 2018, Ars Technica
"NASA has pinpointed next year as the time when its dependence upon Russia to fly its astronauts to the International Space Station will finally end. However, one of the two companies now slated to provide that service, Boeing, has said it will not be able to launch a crewed mission of its Starliner spacecraft until 2018 at the earliest."
Keith's note: That's $88 million per American astronaut.
