Am I reading this right? The 1/3-scale demonstrator version has a 27MW fuel pump?

gonzo's landing was so cool I had to at least try it. I've been at it for hours now. That workload. My checklist got longer, a dose of "again?", a quick review to put it away and I thought about what's left, mentally making room, then just looked at it. I got a little flash of that flip and...

Launch profile improvement This is partial (no way I'm good enough at hot landings yet) but I'm happy with this launch profile and want to share. It reaches 10km/s 7 seconds earlier, at 5:47, and 18km downrange. edit: this has some differences from agentgonzo's setup, but I just took this...

So the apparent heading changes are pure artifact, then -- it's a great circle, viewing the path as an orbit there are no plane changes. Yes, of course: viewing your path from directly above its (orbital) equatorial crossing, every longitudinal lines is curved differently. And now I'm going...

The stock surface HUD will show you this, set the base as your target on the Map MFD and look at the heading tape. Edit: Watching that 16m35 playback makes me think agentgonzo may not have chosen his own nickname. edit2: ... and nobody who was there will ever say "Wideawake" quite the same...

I know there's fans here, it's why I just nabbed it.

I'd go for partial precomputation on log-scale intervals, precompute (log scale 0) 1x...x10, 11x...x20 etc, and (log scale 1) 1x...x100 etc, and so forth Then do the leading and trailing partial intervals at each log scale and look up the precomputed results for any included full intervals.

I'll just leave these here: Apollo Flight Controller 101: Every console explained Going boldly: Behind the scenes at NASA's hallowed Mission Control Center Their Science and Exploration has been a favorite for a long time, just a fan.

Was that a typo? The scrams are _much_ more efficient in the high 20's/low 30's. I keep VAcc as low as hull temperature will allow while the scrams are lit. Trying it just now I didn't dump fuel, hit MECO at 200km ApA and ~65% main, 35% scram remaining.

Just a note, I've found that it's noticeably faster to set terminate-on-shutdown and restart from an icon on the desktop.

One of those whose passing makes the world seem smaller.

Might want to watch the full video, it's ... well, watch.

I keep my place at 79F in summer, it's inside my comfort zone so I'm happy. I can't hear the fans unless I'm really listening for them or there's silence in the room, don't recall ever noticing them while doing anything. Your place is only about 5C hotter, can't see how that'd make much...

One thing I'm not sure of from your posting history: have you docked with the ISS yet? If not, do that first (and that's a big milestone, nobody'd expect a beginner to find that anything but challenging). Interplanetary travel builds on the skills needed to do that, if you don't have a good...
