tater Posted November 30, 2022 Share Posted November 30, 2022 3 minutes ago, darthgently said: Square rigs still go faster cross wind than downwind. The square sails are trimmed to an angle to the beam wind. No different than the angle of attack of a windmill blade. Common misconception. Square rigs were not limited to downwind only. Though they don't point into the wind nearly as well Yeah, the best point of sail for a square-rigger is a broad reach. Downwind the foresails are in the lee of sails windward of them.

Unsure what the best point of sail is on a junk rig, but for a square-rigger it's probably a broad reach (running puts the foresails behind other sails so they aren't doing anything). Yes, reach to broad reach is best in a square rigs typically. Leaning to broad reach (a bit downwind) to the degree the non sail portion of the ship creates drag in the air Quote Link to comment Share on other sites More sharing options...

darthgently Posted December 1, 2022 Share Posted December 1, 2022 The most common phrase of this type I'm aware of is wishing someone "fair winds and following seas". The fair winds would ideally be on the beam and not so strong as too put the rail in the water or dump your coffee, and the swell and waves would be coming from aft mostly so the boat gets to surf a bit and never catch up to it's bow wave, so less hobby-horsing And yes, waves and wind can come from different directions Quote Link to comment Share on other sites More sharing options...

sevenperforce Posted December 2, 2022 Share Posted December 2, 2022 Supposedly they are preparing for a chopstick lift of B7: Let's hope they are doing "now we know the last thing we need to do before launch" work and not "that was fubar, back to the drawing board" work.

Maybe they just need to make some final modifications to the pad that they can't do with B7 still there. I imagine there might be parts that need to be craned in through the center ring.

RCgothic Posted December 2, 2022 Share Posted December 2, 2022 After the detonation event, the raptor vents were flex-hosed to the launch mount through the open aerocover panels. Both booster and launch mount need modifications for an alternative routing for launch, and then the booster needs its aerocovers reinstalling. I wouldn't write B7 off yet.

Brotoro Posted December 8, 2022 Share Posted December 8, 2022 (edited) Yes, the external (and onboard) video of the boostback and after was great.

Ultimate Steve Posted December 8, 2022 Share Posted December 8, 2022 Dear Moon crew has been announced! Notably, Tim Dodd is going! There are 8 primary crew and 2 backup crew. No timeline update. My biggest hope was that we would get at least one musician, and we appear to have gotten at least 3! (2 of them are not listed as musicians but are also musicians) Full list: DJ & producer Steve Aoki Youtube creator Tim Dodd Artist Yemi A.D. Photographer Karim Iliya Photographer Rhiannon Adam Filmmaker Brendan Hall Actor Dev Joshi Musician T.O.P. Backup crew: Dancer Miyu Snowboarder Kaitlyn Farrington Would be interesting to see dancing in zero g. There was some talk a while back about having one or two professional astronauts along as well, if that is still the plan, they have not been announced yet.

tater Posted December 9, 2022 Share Posted December 9, 2022 Odd choice for 9 crew. 8 would have allowed more options (2x Crew Dragon to/from LEO). Quote Link to comment Share on other sites More sharing options...

They might need a pilot for returning crew dragon? or maybe just want one for some kind of safety margin? Cuz then it would 3 crew dragon trips, each dropping off 3. Although I would have thought that uncrewed return of a dragon would be proven tech because of cargo dragon. Quote Link to comment Share on other sites More sharing options...

Oh, yeah, I guess I forgot that Isaacman trained up to astronaut level effectively (he's got loads of jet time). Still, 4 crew on an automated Dragon with 1 of them trained to be able to respond to ground control commands in an emergency is every bit as safe as 9 people going around the moon—or doing the Moon trip from the pad, and back to the pad on Starship. I suppose one way to look at it is this trip is not any time soon. Quote Link to comment Share on other sites More sharing options...
Ultimate Steve Posted December 9, 2022 Share Posted December 9, 2022 It's also possible that for ferry trips like these they fit the additional three seats. I'm not sure how difficult that would be this late in development though, and iirc there was some constraint they were up against, maybe splashdown g forces or something.

SunlitZelkova Posted December 9, 2022 Share Posted December 9, 2022 Very exciting! Some questions and thoughts come to mind- -We know Polaris Mission III will be the first crewed Starship mission, so… -Are there any potential differences between the first iterations of crew Starship for Polaris Mission III, and the crew Starship for dearMoon? If not… -I wonder how soon dearMoon would then come after Polaris Mission III. Perhaps Polaris may inadvertently allow for a glimpse into a more realistic dearMoon launch date?
