@Marc_Desm@peter_stoychev@grnmedina_chris@thunderf00t Did the Saturn V have an upper stage capable of reuseability? No. The upper stages were made out of materials that would burn up upon reentry, Starship is far larger than the upper stages of SV, and is made out of stuff that doesnโt burn up on reentry
@thunderf00t Wow i'm a Musk fan now, btw i checked and with 5 engines it took ~7.7s to achieve 1000 km/h change in velocity, with consumption of 650kg/s/engine gives ~25t of prop which is not even 2% of the total prop capacity plus they dumped a lot of prop after SECO, so they didn't use 100%
@GaryWilliamsIT@Marc_Desm@thunderf00t 2/ and with a brand new reusable upper stage that is pushing the limits it's better to play it safe and do suborbital flights first, because if something fails on Starship that would make it uncontrollable while on orbit, it could reenter over populated area
@GaryWilliamsIT@Marc_Desm@thunderf00t 1/With V1 orbit wasn't really important, they just wanted to prove Starship could reenter, with V2 that was a goal, but it had a lot of issues but they probably could've got to orbit on F11, but it would've taken longer to approve an orbital mission, and they wanted to move to V3
@Marc_Desm@thunderf00t It can make orbit, because the extra propellant needed to get to orbit compared to the current suborbital trajectory is tiny. If they would burn the engines for like 5-10 second longer it would be in orbit.
@Marc_Desm@thunderf00t Hmm idk, maybe that last flight it carried an estimated 40t+ of dummy and real satellites to sub-orbit, and the additional deltaV needed for LEO is marginal, plus you could see they vented propellant for almost 10min after SECO
@ByGoalZ@ScottLikedSLS The V3 Starlinks will reportedly be around 2t, so probably they would make the Simlinks similarly heavy to simulate the real satellites in the dispenser. And with optimisations i meant that right now they probably couldn't launch 100t into orbit, but in like 10 flights maybe
@ByGoalZ@ScottLikedSLS Flight 12 launched an estimated 44t, with one engine out and a longer burn, and it vented its propellant for quite a while after seco, so iโd say itโs surely 65t<, with optimizations it could get near 100t in the not so distant future
@RippleXrpie Theyโll never get over 50% (currently ~28%), which they would need to get anything done, and they probably would get HUGE backlash for such a proposal
@n_brandeggen@Booster_11 Almost, but the yaw can be countered without it having an affect on roll (bc u miss the CG in both axes with the thrust-vector, and then just correcting for one)
@kmh@Booster_11 You can, its just a bit trickier, bc u would have to miss the CG with the thrust-vector on both axes, which would mean a yaw as well at the same time, and then the control system would need to โcatchโ that tipping moment
