I am starting a new thread for this mission which should fly this year.

Been thinking about ways to visualize the evolving fuel situation, and whether it was converging towards anything or otherwise showing trends. I thought of two ways.
And of course, between the time I started plotting and when I post this, now they're projecting to hit the Earth. Ah well. |

eventually have caught up and overall each improvement was been greater than the proportional loss during the time between updates Well, I'd suspect that a stuck valve works both ways. Which suggests that there is now a helium & NO/NO4 froth filling the oxidizer and pressurant tanks. Which might not be so bad, having some liquid in the pressure tank might have helped to close the wonky valve. The analogy I think of is just cracking open a warm 2 litre bottle of soda- you get an initial blast of carbonated water, but that quickly subsides and what mostly escapes the opening (here the cracked tank) is the gas, not so much the liquid. Perhaps the trick here would be figuring out a way for 'ullage thrust' to push the "flat soda" oxidizer (and fuel) into the engine for a burn attempt? |
