Kistler Stage 1

LOx/Kerosene propellant rocket stage. Stage burns for 35 seconds to place itself on return-to-launch-site trajectory for recovery. Therefore to calculate performance 12,400 kg propellants for flight back to launch site should be added to empty mass. Empty mass also includes six parachutes, landing bags, and is calculated, based by apportioning total vehicle empty mass.

Cost $ : 10.000 million. No Engines: 3.
