Per-launch costs can be measured by dividing the total cost over the life of the program (including buildings, facilities, training, salaries, etc) by the number of launches. With 115 missions (as of 6 August 2006), and a total cost of $150 billion ($145 billion as of early 2005 + $5 billion for 2005,<19> this gives approximately $1.3 billion per launch. Another method is to calculate the incremental (or marginal) cost differential to add or subtract one flight — just the immediate resources expended/saved/involved in that one flight. This is about $60 million U. S. dollars.<21>
Early cost estimates of $118 per pound ($260/kg) of payload were based on marginal or incremental launch costs, and based on 1972 dollars and assuming a 65,000 pound (30 000 kg) payload capacity.<22><23> Correcting for inflation, this equates to roughly $36 million incremental per launch costs. Compared to this, today's actual incremental per launch costs are about two thirds more, or $60 million per launch.

The Shuttle can do much more things even compared with an Ariane V with coming crew vehicle. But to launch satellites an Ariane or a Delta or a Proton (the only other operational heavy lifts) are much cheaper.
besides regarding Proton it stands "which makes it one of the most successful heavy boosters in the history of spaceflight"... not THE most.
You cannot compare with a Saturn which had a completely different function
As of 2006
, Arianespace held more than 60 percent of the world market for boosting satellites to geostationary transfer orbit (GTO).<4> More than 240 commercial launches have occurred since May 22, 1984, and Arianespace states that the total number of launch contracts signed since Ariane launches commenced operations in 1984 is 285
Arianespace and EADS owns now "half of Soyouz" which will permit independent maned flights from Guaina
Soyuz ACTS (2012/....)
Soyuz ACTS (Advanced Crew Transportation System), also known as Soyuz-K, is a proposed version of the Soyuz design capable of achieving lunar orbit. The upgrades could include a new habitation module developed by the European Space Agency. A novel, rocket-based precision landing system may also be implemented.<3> Missions could be launched from Baikonur or Guiana Space Centre.<4>
