Energia EUS is the Energia launch vehicle with EUS Energia Upper Stage.
Energia EUS can throw directly into Trans-Mars Trajectory 29.3t for C3=15m2/s2. Transit time 10 months.
Proton K with the 11S824F upper stage can throw 6.22t directly to Mars. Transit time 6 months.
Soyuz ST was developed to launch commercial satellites in orbit. Quoted price is $30-50 million, but the same launch vehicle with Fregate upper stage costs $35 million.
Soyuz FG is the new launch vehicle used to lift Soyuz and Progress spacecraft to ISS. It launched Progress spacecraft on May 20, 2001, and November 26, 2001.
Shuttle average launch cost in 1988 was $245M based on 6 launches per year. That is due to high overhead cost. Cost of each additional launch was $63M. Price to rent the entire cargo bay for a commercial launch was $142M in 1992. Total cost for Shuttle in 2002 was $3,272.8M so based on 6 launches the average cost is $545.5M. Incremental cost for additional launches was not published in the NASA 2002 budget.
