Mun Flyby & Orbit

Your first trip to the Mun! Learn how to achieve orbit and perform a flyby. This guide covers the essentials for a successful Mun mission in Kerbal Space Program.

So, you're ready to head to the Mun? Awesome! It's the classic first step beyond Kerbin, and honestly, it's a rite of passage in Kerbal Space Program. Think of it as your first real space adventure, a bit like the real-life Moon landing, but with more explosions and Jebediah Kerman. ### The Mun: Your First Destination The Mun is Kerbin's natural satellite, and it's your primary target for this mission. It's got about the same gravity as our own Moon, and importantly, no atmosphere. That means parachutes are a no-go for landing, so you'll need to rely on good old-fashioned rocket power to slow down. ### Getting There: The Basics To get to the Mun, you'll need a spacecraft with enough Delta V (that's the change in velocity your rockets can provide) to get into orbit around Kerbin, then transfer to the Mun, and finally, slow down enough to either orbit it or land. A good target for your initial Mun mission is around 5500m/s of Delta V. Don't worry if that sounds like a lot; you'll get a feel for it as you build more rockets. ### Orbiting the Mun Once you're on your way to the Mun, the goal is to get into a stable orbit. As you approach, you'll want to burn your engines *against* your direction of travel (that's a retrograde burn) to slow down. Keep an eye on your maneuver nodes in the map view; they're super helpful for planning these burns. Aim for an apoapsis (the highest point of your orbit) and then a periapsis (the lowest point) that are both above the Mun's surface. If you do it right, you'll be circling the Mun like a pro! ### Landing on the Mun Landing is the trickier part. You'll need to perform another retrograde burn when you're at your lowest point (periapsis) to start descending. The key here is to burn *straight down* relative to the Mun's surface. You can do this by pointing your ship directly at the ground (your navball will show a pink circle with a dot in the middle when you're oriented for landing). Cut your throttle as you get close to the surface, and try to touch down as gently as possible. Remember, no parachutes! ### A Word of Caution Don't be discouraged if your first few attempts don't go perfectly. The Mun is a challenging but rewarding target. You might end up crashing, running out of fuel, or getting stuck in a weird orbit. That's all part of the learning process! Just keep tweaking your designs, learning from your mistakes, and soon enough, you'll be planting flags on the Mun.
