zombiphylax Posted November 5, 2011 Share Posted November 5, 2011 I\'ve been seeing a lot of videos lately where people are taking off and doing a gravity turn the opposite way I\'ve been normally doing them. Maybe I\'m under the wrong impression, but isn\'t the solid red line on the navball south? Isn\'t it easier to drop to the east rather than west?

foamyesque Posted November 5, 2011 Share Posted November 5, 2011 Solid red line is north. East is 90, south is 180, west is 270. Link to comment Share on other sites More sharing options...
zombiphylax Posted November 5, 2011 Author Share Posted November 5, 2011 Ok, I can read it now, forgot it was from pilots view. So I have been launching east though, what\'s with everyone launching west? Link to comment Share on other sites More sharing options...

Xivios Posted November 6, 2011 Share Posted November 6, 2011 Ok, I can read it now, forgot it was from pilots view. So I have been launching east though, what\'s with everyone launching west?You haven\'t shown us any of these videos, but I\'m going to assume your\'re still launching West.The red line, at launch, with the nav-ball seen from the top-down, indicates North. It does this by facing south, as seen from the top of the nav ball.Remember, you are looking at the exterior of the nav-ball, not the interior. Every direction on it is reversed. For you to see the line indicating a northerly direction of travel, it must be painted on the southern part of the ball. For you to see a line indicating a westerly direction of flight, that line must be painted on the eastern side of the ball.From launch, at KSC, without touching the camera, east to the right, out over the ocean.

Jarnis Posted November 6, 2011 Share Posted November 6, 2011 From launch, at KSC, without touching the camera, east to the right, out over the ocean....which happens to be the logical direction anyway as you probably would not want to drop your boosters and spent stages on top of the VAB and pad, now would you? Real Rocket Pilots aim slightly towards east as soon as the rocket has cleared the tower to ensure that it is already over the ocean when first SRBs burn out (never mind that doing that with a large rocket can be somewhat hazardous... but I think of the poor technicians on the ground. You should too!)It is as if KSC was built on this site so this would be so, on purpose ;P Link to comment Share on other sites More sharing options...
AndrewCoja Posted November 7, 2011 Share Posted November 7, 2011 It\'s easier to launch to the east as the planet is already rotating east. Launching west, you have to overcome 200m/s or however much to the east before you actually start going east. Whereas by launching east, you get a free 200m/s.

To 90.These videos are posted in the Subreddit dedicated to this game. Most of the orbit and moon shot tutorials show a lot of people launching west. I was wondering if there was a reason.

With old versions, it didn\'t matter which way you pointed the rocket at.With 0x12, the planet now rotates and launching to east (90) saves fuel. It also happens to be the logical inclination to launch to when heading for the Mun (again, no Mun in 0.11 and before) Link to comment Share on other sites More sharing options...

So, it was at least 12.1. With only one video I seen have they brought up a good reason: if you can fight the orbit of kerbin, you only need 1/2 an orbit before you can attempt a munar injection, what about the rest?

Hypocee Posted November 9, 2011 Share Posted November 9, 2011 states it\'s to increase the length of the window for entering the Mün\'s sphere of influence, reducing the chances of a total miss, at the expense of delta-v. Maybe other people felt the same. Giving up the eastward boost really isn\'t that big a deal; the explicit goal in choosing Kerbin\'s day was to make the free boost a nice little bonus, but not prohibitive. OTOH giving up the extra delta-v at the Mün from orbiting the wrong way...my view is that you can do a lot of midcourse correction for that much juice, but that\'s just me.I hit Münar orbit and returned on my first try on stock parts, sleep-deprived, paying attention to potential timewarp bugs I was testing for, swinging my nose all over the sky on every burn, disoriented, several degrees off on everything, learning the cameras, having read/watched nothing but that a Hohmann\'s transit time leads by about 60 degrees. But the pioneers making those videos had no way of knowing it would be that easy . Link to comment Share on other sites More sharing options...
