@flcnhvy @Erdayastronaut @DiscoverMag Annoying that @ULA perpetuates myth that Delta IV Heavy or Atlas V can do some orbits that Falcon Heavy can’t. This is absolutely false. FH would have to go full expendable for GEO direct, but that’s very rare.

@Erdayastronaut @DiscoverMag Massive delta velocity slam from highly elliptical Earth orbit using a fully retanked, but lightened up Starship with no heat shield or fins/legs. Best choice for the impatient. Ion engines are too slow.

@WorldAndScience It’s possible to make a self-sustaining city on Mars by 2050, if we start in 5 years & take 10 orbital synchronizations

@martinengwicht @macodiseas @katlinegrey Exactly. That’s the critical point for Starship/BFR: more payload than the biggest rocket ever made, but for less money per launch than the smallest (orbital) rocket. Without something that lowers orbital flight cost by 100X, humanity will never be a multiplanet species.

@ludan27 @Erdayastronaut @JeromeJaccard @Robotbeat @alan1bernard Yes, but single stage to orbit with no payload is pointless. Add Super Heavy rocket booster & orbital payload is gigantic. Only need booster on Earth, due to deep gravity well & thick atmosphere. Starship alone on moons & Mars.

@Erdayastronaut @annerajb Won’t land propulsively for those reasons. Ultra light heat shield & high Mach control surfaces are what we can’t test well without orbital entry. I think we have a handle on propulsive landings.

@bartjehoel @djenkins6 Correct, pure electric. Wish orbital rockets could be so too, but there’s no escaping Newton’s Third Law. SpaceX is already developing high efficiency CO2 capture with H2O to form liquid CH4 (methane) & O2. Critical for propellant production at Mars Base Alpha.
