BFspaceship looks alot like penguin to be honest. Same colors and simulair shape. Quote Link to comment Share on other sites More sharing options...

Unrelated: would a Falcon Heavy have been able to deliver Parker Solar Probe with the same performance as the DIVH last night? My guess is that it would have had to expend at least its core.

Launch C3 was ~154 km2/s2. The baseline D IVH curve is twice as high as FH, so I can only imagine that even with a Star48 under the fairing, FH has trouble matching DIVH under any conditions. Looks like expended is maybe around 70 for FH? The Star 48 might well get it there. Recovered is closer to 40 as a baseline for FH, so likely falls short.

Looks like expended is maybe around 70 for FH? The Star 48 might well get it there. Recovered is closer to 40 as a baseline for FH, so likely falls short. Let's see here. The Star48B (with or without vectoring) masses 126 kg dry and 2137 kg wet, with an Isp of 286s. The probe, with fuel, masses 685 kg. So the Star delivered 3.495 km/s. A Venusian Hohmann costs about 3.5 km/s out of LEO, while a Mercurian costs 5.5 km/s. So we know the DIVH pushed a payload of 2.8 tonnes at least 2 km/s beyond LEO. The reusable FH, sandbagged, delivered the Roadster and an indeterminate amount of ballast to at least 3.6 km/s beyond LEO. Back of the envelope says that the Block 4 FH could have done it with center-core expenditure, though I don't know whether they'd be able to manage RTLS for the side boosters. Block 5 FH could likely have done it with RTLS on the side boosters but would still need to expend the center core. 10 minutes ago, tater said: Interesting.

tater Posted August 12, 2018 Share Posted August 12, 2018 The SpaceX event is a crew thing, like the one that was just at the Starliner facility, apparently. Nothing too interesting, unless we get to see the inside of actual flight hardware. Quote Link to comment Share on other sites More sharing options...

But a Condor, Heron or Swan soaring across the void sounds... impressive. Quote Link to comment Share on other sites More sharing options...
