This one is gonna be going incredibly fast when it comes down. Almost 1000km downrange, I’m guessing it’ll be one of the fastest entries ever. Anyone know off hand if they’ve recovered a booster even further than that? Quote Link to comment Share on other sites More sharing options...

RedKraken Posted April 10, 2019 Share Posted April 10, 2019 What sort of acceleration limits are we going see on FH today? 3g? maxq? 30kPa? Have the block 5 sea level engines raised their isp (from 282s- 311s) ? What chamber pressure are they at now? How much fuel do you think will remain in the center core after booster sep? 120t? A bit of prop gets burnt during engine startup from T-3s to T + 0s How much prop do you think is in the tanks at liftoff? 405t? Quote Link to comment Share on other sites More sharing options...
KSK Posted April 10, 2019 Share Posted April 10, 2019 Enjoy the launch folks. My crossed fingers are set to 'nominal' but I'll be sleeping through this one sadly. No prizes for guessing what I'm watching over breakfast though. Quote Link to comment Share on other sites More sharing options...

Geonovast Posted April 10, 2019 Share Posted April 10, 2019 Well... I might not be able to see the rocket, but at least I won't have to stay after work or rush home... Quote Link to comment Share on other sites More sharing options...

mikegarrison Posted April 11, 2019 Share Posted April 11, 2019 I was using a globe on a desk today to explain to people at work why launch windows. "If you want the rocket to end up *here*, you need to wait for the Earth to rotate around so Florida is *here*." Quote Link to comment Share on other sites More sharing options...

Well, I did point out that the inclination thing doesn't really apply to equatorial orbits. Quote Link to comment Share on other sites More sharing options...

If a train leaves orlando travelling If a rocket launches from Canaveral heading due east, won't it always end up with a descending node over central Africa-ish at about 23 degrees inclination?

You may head north... And the Earth rotates. Quote Link to comment Share on other sites More sharing options...
