Asteroid redirect mission

[TryHardNinja]

I need some help. Whenever I try to complete this mission in the training area my capsule ends up millions of miles away from the asteroid even when I 'fine tune' the burn as they suggest. I get the capsule on to the green line of the asteroid but it arrives at the rendezvous way before the asteroid does. I've also tried burning towards it but that takes forever and I run out of fuel before I get there.

Can anyone give me any pointers? I've tried it at least a dozen times now.

Thanks.

I'm pretty sure the tutorials are always messed up somehow.

Its not necescarilly a point and shoot rendevouz... Also, it depends whether or not the asteroid is in deep space or kerbin orbit, or what have you...

Heres some tips that you could probably use if you havent already:

-Select the asteroid as a target while setting up a manuver node...
-Look at the encounter nodes provided in the map view
-See if they are close enough for a proper rendevouz
-Correct as needed...

Just because the fact that you got the lines close doesnt mean much... Were talking about Infinite tracts of space... They can and most likeley will still be VERY far apart.

The manuver node, targeting, encounter and rendevouz system provived by the game are very helpful once you know how

Youtube is very helpful if you dont already know how to use these.

If you are still having issues, all i can really do is reccomend going on youtube, as this isnt really something that you can just explain with words...

All the advice im giving you is just based on the assumption that you are new to the game...

The four points above are actually already set up for you in the scenario, and the encounter node says something like 82km, which I assume is close enough. You are encouraged to 'fine tune' this but when I do the encounter for the asteroid is still something like 11 million miles away. It's rather like my capsule swings around on its orbit but the asteriod isn't moving fast enough to arrive at the same time (even though the encounter node says it's correct).

Could you have a go yourself and let me know what happens? It's the last one in the tutorial section.

Thanks.

Same problem here... At the end of my frustration, I use the manuver point set by the kerbal.. At the orbit interception there were some distance between that asteroid and I. And so I direct my ship to the waypoin prograde vector and keep thrusting!! and so my orbit inclination went almost 90 degree :p BUUUTT THEENN it came closer and out from no where, I saw the TARGET. Tellow mark from distance 66km and kept coming closer and I thought, I will succeed...

At the end of the story It flew pass through me with distance 9km and then went faster than my ship.. and there it goes.. my happiness.. left me in emptyness.. another failure..

You know you have to cancel out your velocity relative to the target by burning retrograde to it, right?

Yea I did that.. set the nav ball to target, and then burning towards retrograde. but when the velity reach 0, still too far.. I guess there's something I miss.

and btw if we are burning retrograde when setting the nav ball to target is that means that we are burning to target's orbit retrograde?

In target mode burning retrograde means you're cancelling out your velocity relative to the target. If you're still away from the target you'll want to have your retrograde vector on the antitarget vector (the pink marker), which means that you're heading straight towards the target - the opposite is then automatically true: your prograde vector is in the same direction as the target.

At what point do we burn retrograde? As soon as we've finished the first burn or later? Also which is the retrograde symbol.

Thanks.

Set the Asteroid as your target. You should see the path through Kerbin's SOI. The trick is to try to place a maneuver node so that your path follows the asteroid's path (but going the opposite direction). Near where you'll exit Kerbin's SOI, you'll want the paths to be as close as possible (it's OK if the paths diverge near Kerbin)

If you zoom out, you should see close encounter markers. If you're within 1000km, then you're good to go. Otherwise, make small adjustments to the maneuver in all directions (prograde, retro, normal, radial, earlier/later), and see if you can get the separation closer.

After you exit Kerbin's SOI, you can make further small adjustments to get the close approach even closer.

I have a guide on docking here: http://steamcommunity.com/sharedfiles/filedetails/?id=289580294 . Step 4 is basically what you'll want to do (though the distances and speeds will be much higher).

Ok, so thats why my velocity is increasing while burning to the pink marker as you said. But then I have to cancel it again right? Thx btw for the explanation.. helps a lot. :)
