Nope. Off once again to Jupiter and Beyond !
It is intense,I keep skipping out. Dous landing gear damage disabled count as a cheat,it's so sensitive. :blush:
Nope. Off once again to Jupiter and Beyond !
My first video; There were a couple of mistakes but overall it was a pretty good run. Timed at 18 minutes 16.8 seconds from "throttle up" to "wheels stop". (XR2 MET counter: 18 min 07 seconds). Max velocity (GS) was 14.62 km/s
I added a lua script to display some info of the run and a keypress logger to show the keys. Flight was made without a joystick.
I will update if I get a better score.
What is the proper launch heading (compass degrees) from KSC to Wideawake? This will be a great test for an autopilot I have been doing some work on!
nvm, found it in a video. 110 degrees.
108 degrees is a bit better.

do you have numbers that are more accurate (after the decimal place)? (I wouldn't expect it if you do things by sight, but I can hope)
Estimate the TOF (Time Of Flight) and calculate how many degrees the Earth will rotate by the time you get there. Add the result to the target's longitude and calculate the bearing for the new target coordinates.
Example:
The average flight time for this challenge is ~20 minutes. In that time Earth rotates by [math] \frac{20 \cdot 60}{86164.1} \cdot 360^\circ \; = 5.014^\circ [/math]
Turn the result back to degrees: 1.8546 * 180/π = 106.26°
The more accurately you know your TOF the more accurate the calculation. If you managed to get there 2 minutes earlier, the azimuth should have been different, because the Earth would have rotated ~0.5° less.
If you redo the calculation for a flight time of 18 minutes, you get a launch heading of 106.51°

Ok, this looks great! where exactly does that 86164.1 come from, though?
I think it has something to do with the seconds in a day (86400), but I'm not sure.

Right, forgot about that giant ball of gas out there. I get it now.That's the time Earth takes for one rotation. 86400 is the time between noons (the time the Sun is highest over the horizon). They are different because Earth orbits the Sun.
And remember that the bearing has to be continuously updated. The heading depends on your actual position and not on your starting point.

:woohoo:
Anyway, VSFX, you can add my score to the board if you want. The pic says 26:42 but the real Wheel Stop was around 26:37 (the time to deep breathe, switch to the upper panel and take a screenshot, before letting the joy fill my feels (We all know that feel, bros )) with GS of 11 600 m/s.
No, not continuously. The whole point of taking Earth's rotation into account is to avoid that. You take off, point to that heading and level out.
Yes there is a little bit of adjustment, because the trip isn't with constant speed all the way, but you get fairly good results.
---EDIT--
Ah, unless you mean it the other way. That you hold the original heading/direction and don't try to follow the calculation's azimuth all the way to WIN.
{snip}..You cannot travel on a constant heading between two points on the surface on a sphere, unless they have the same longitude or are on the equator. If you follow a constant heading (like when you trace the course on a map) you are actually traveling in an arc over the spherical surface...{/snip}
Time for another run. First one under 18 minutes. XR2 MET: 17:53
Playback attached.*
*The counter in the playback starts at throttle up, 12 seconds earlier than
the real flight.
