They wanted to adjust the road closure for later in the day to move SN9 to the pad since they expected it to be windy in the morning.

I could be wrong but I feel like that is the bottom end, where the downcomer attaches, and the downcomer simply sheared off entirely at the weld. Or it could be the top end. But if so, is it missing a cap? It wouldn't be much of a header tank if it was just open like that. Quote Link to comment Share on other sites More sharing options...

sevenperforce Posted December 11, 2020 Share Posted December 11, 2020 Love this render... A little more math... One thing I'm really curious to know is whether they were planning on a single-engine landing burn or a two-engine landing burn. My gut, even without doing maths, is that they were planning on a single-engine burn from the beginning, because that would give them the largest window for fine adjustments all the way down (hoverslams are hard). So the plan would be to use two engines to execute the flip, providing roll, yaw, and pitch control, and then shut down one engine as soon as roll was appropriately damped. Contributing support for this hypothesis: the engine that either flamed out or was shut down did so almost immediately after the flip was completed. In the view from beneath, you can really see how that engine damps roll and then immediately shuts down. Shutdown was almost exactly T+6:39.00, 1.33 seconds before my pixel-counting started (I needed the ground to come into view or it wouldn't have worked) and exactly 4 seconds before impact. The fire from the other engine was already green at this point, so we can assume it was already only providing a single gee of thrust. Thus we extrapolate back 1.33 seconds at 30.09 m/s to give us an altitude of 119.8 meters at the shutdown of that engine. Remember your kinematic equations: v2 = v02 + 2aΔx. So if you're 119.8 meters above the ground, dropping at -30.09 m/s, and you need to hit 0 m/s by the time you close that distance, what acceleration do you need? Spoiler v2 = v02 + 2aΔx (0 m/s)2 = (-30.09 m/s)2 + 2*a*(-199.8 m) 0 = 905.41 m2/s2 + 2*a*(-199.8 m) -905.41 m2/s2 = 2*a*(-199.8 m) -905.41 m2/s2 = a*(-399.6 m) (-905.41 m2/s2)/(-399.6 m) = a 2.27 m/s2 = a To counteract gravity and slow down Starship in a perfect suicide burn, the engines needed to produce 2.27 m/s2 plus the acceleration of gravity, or about 1.23 gees. That's not much thrust at all...clearly much less than would be expected if you were doing a two-engine suicide burn. Thus, I think we can safely conclude that they were intending a single-engine landing burn all the way down. Quote Link to comment Share on other sites More sharing options...

The weird thing is, I'm way more concerned about the impact this incident will have on Starship progress than I am about SN8 exploding.
