The Hill's NASA's Europa Clipper has been liberated from the Space Launch System is quite an illuminating read about the politics of space launch. However, I noticed that it also says:
Both the economics and physics of getting to Europa change if SpaceX’s Starship, currently under development in Boca Chica, Texas, becomes available to launch the Europa Clipper in the mid-2020s. The Starship is meant to fulfill SpaceX’s CEO Elon Musk’s dreams of settling Mars. But the massive reusable rocket would be available for other things, presumably including sending probes to the outer planets.
The massive cost savings by using a commercial launcher for the Europa Clipper creates other possibilities. The Europa Lander could be placed back on. A mission to Saturn’s frozen world Enceladus may also be greenlit.
Question: In what ways would the "physics" of getting the Clipper to Europa change if Starship was used instead of SLS? Are the orbital mechanics of interplanetary flight changed? Number of stages or number of flybys different?
It's certainly quite a delta-v challenge to get from Earth to Jupiter and then deep enough down in Jupiter's gravitational well to match Europa's orbit and then land safely on its surface without any atmosphere on the moon for aerobraking. But how would Starship and SLS solutions differ?
