"The three CBC core stages of the Delta 4 Heavy will fly suborbital trajectories. The Delta second stage will enter parking orbit. Then Stage 2 will fire again to reach escape velocity, and end up in an solar orbit that I estimate around 0.37 x 1.0 AU. Stage 3 will then fire to add even more speed, and it and the PSP will end up in a 0.21 x 1.0 AU orbit."
Tri boostre CBC Delta 4 Heavy majú suborbitálnu trajektóriu. Druhý stupeň Delty vstúpi na parkovaciu dráhu. Znovu spustením motorov 2. stupňa sa dosiahne úniková rýchlosť a skončí na obežnej dráhe okolo Slnka, ktorú odhadujem okolo 0,37 x 1,0 AU. 3. stupeň potom pridá ešte väčšiu rýchlosť, a PSP skončí na orbite 0,21 x 1.0 AU.
