    How to get to orbit with only one burn of each stage?

    clarification

    Sort of.

    The first stage just lobs the craft to about 50-80km, and about 3km/s.

    Wait, that doesn't sound right, unless i'm misunderstanding. The SpaceX site shows the Falcon 9 reaching speeds of Mach 2 at MAX-Q, 78 seconds in to the flight. That roughly translates to 1,534mph or 686m/s. There is no way there are going 3km/s, that's Mach 8.7 lol

    Were you meaning total ÃŽâ€v?

    Like others have said, the aerodynamics have come a long way from the early days. Fins actually matter now. Nose cones help reduce atmospheric drag, etc. Make sure you are using engines with Thrust Vectoring while in the atmosphere because that increases responsiveness and reduces the tendency for it to tip. Also, pay attention to center of mass and how fuel is expended while ascending because many designs can become especially top heavy as they ascend. (Again, depends on how you built the vehicle.)

    It's especially true that going WOL (wide open throttle) while ascending not only generates excessive heat (if your TWR is high enough) but it makes it a lot harder for Reaction Wheels, Thrust Vectoring, SAS to keep the launch vehicle on it's current heading. So bringing down your throttle a little may also provide a more stable ascent and gravity turn.

    Finally, with all the aerodynamic changes, a lot of us stopped the usual "gravity turn at 10k" method. It's just fine to start your gravity turn at 1k and slowly get to 45 degrees by 10k and then maintain that until you reach your target apoapsis.

    Oh, and never forget to check for wobbling or anything weird like that. Struts and more struts. Just had to throw that out there because a spacecraft noodle like to flop over and do all sorts of crazy things.

    I hope some of this helps!

    Ah yes, that moment you realize Kerbal Space Program is like crack and you binge play for hours. Was it 6 hours straight or did you take a break? ;)

    There is a lot to learn. Don't get overwhelmed. Take your time and get a good grasp on the basics. You need to build upon these skills to progress and do a lot more going forward.

    People on Store/Steam who are saying that it is not updated, just calm down and wait a sec... it will be there shortly

    I think you're missing the point. KSP *queued and UPDATED* for us on Steam. I watched it download and install. But when running the game, it's still v0.24. Something is very obviously borked.

    I think this has probably happened to a lot of people when first starting out... Building a jet or SSTO for the first time.

    I must have spent 10 hours building the most awesome looking jet. It looked so realistic and of course it will fly, it has wings...

    Boy was that a wake up call when I stuck it on the runway. And that was after attempting to lift off. Hours of work, for a cool looking coffee table coaster.

    I learned a lot that day...

    Building a space station is cool. But rendezvous and docking can be one of the most difficult things to learn. If you're starting out, I recommend moving from orbits to larger orbits and intersects with planetary bodies or moons. Specifically Minmus. It orbits further from Kerbin, so it's relative velocity is slower compared to the Mun and it has a smaller mass and less gravity, making landings exceptionally easier than the Mun.

    I would suggest getting a Minmus landing under your belt, then the Mun, and then focus on the space station and planetary phase angles.

    I wish I would have had somebody tell me to do it that way when I first started because I learned the hard way, with a lot more concepts thrown at me then a gentle easing in to it. I don't regret it, but the last thing you want to do is become frustrated.

    Go to Minmus and then report back. ;)

    Good luck!

    MUN landing.

    Face your lander prograde and use your engine to bleed off lateral speed. If you are doing it correctly your prograde marker will move (slowly) to 0 degrees, you will be moving stright up/ down. Keep your speed less then 10 m/s and you will have a smooth landing.

    No. Burning prograde will slam you in to the Mun. I think you either mistyped or have your terms confused. You burn retrograde to slow down. Designated by the circle with an X on the navball.

    MUN landing.

    What can I do to prevent my Lander from doing this?

    You need to kill your angular momentum. Simply point your craft at the retrograde marker (circle with an X) on your navball and burn until it moves toward dead center. That will allow gravity to pull you straight down.

    Keep in mind, if your navball is set to "surface" mode, the retrograde marker may shift a bit as you approach the ground, because it reflects surface angles. (Landing in the rim of a crater for example)

    Hope this helps!
