This is the price that NASA will have to pay ($55.8 million to be precise) per astronaut, from 2013 to 2014 for 6 of them to be transported up to the ISS via Russian Soyuz capsules.
Currently NASA only pays $26.3 million for each astronaut taken up by the Russians, but with the US shuttles due to go into retirement by the end of this year, future missions will depend on the Soyuz for delivery of manpower.
NASA has already agreed to pay $51 million per seat for 2011 and 2012, with the increase in price being needed for the construction of extra Soyuz capsules to meet the increased demand for flights.
