Atlas V: Razlika med redakcijama

Zgornjo stopnja Centaur uporablja kriogenična propelanta tekoči vodik in tekoči kisik. Poganja jo eden ali dva Aerojet Rocketdyne RL10A-4-2 motorja, vsak razvija 99,2 kN (22 300 funtov) potiska. INU (inertial navigation unit) ponuja inercialno navigacijo in kontrolira pritisk v tanku in pretok goriva. Motorji se lahko ponovno zaženejo, tako je možno "parkiranje" v [[NZO]] in potem čez nekaj časa zagon motorje v [[geostacionarna transferna orbita|geostacionarno transferno orbito]] - GTO.<ref name=afsp200903>{{cite web|url=http://www.afspc.af.mil/library/factsheets/factsheet.asp?id=3643 |title=Evolved Expendable Launch Vehicle |date=Marchmarec 2009}}</ref><ref name=aip2006>{{cite web|url=http://unitedlaunchalliance.com/site/docs/publications/CentaurApplicationtoRoboticandCrewedLunarLanderEvolution.pdf |title=Centaur Application to Robotic and Crewed Lunar Lander Evolution |authorsfirst1=Bonnie |last1=Birckenstaedt, |first2=Bernard F. |last2=Kutter, |first3=Frank |last3=Zegler |publisher=[[American Institute of Physics]] |year=2006 |page = 2 }}</ref>
