Ariane 5ES
Part of Ariane 5 Family
Ariane 5V
Ariane 5V
Version of the evolved Ariane 5 using a version of the EPS storable propellant stage instead of the new LOx/LH2 stage. Result was a payload to GTO of 8 metric tons. The use of the new Aestus restartable engine in the upper stage fitted the vehicle for space station logistics missions or launch of space probes requiring complex orbital maneuvers. Specifically designed to orbit ESA's Automated Transfer Vehicle (ATV) resupply vehicle for the International Space Station.
