I did hear about this cool cycler thing though ;), You're basically transferring your energy into the body you're orbiting. The Jolian system is terrific for playing with gravity assists. I usually do all that but end up smacking the planet at 10,000 km/sec. A gravity turn is a maneuver used to launch a craft into, or descend from, orbit around a celestial body while using minimal fuel. Oh, I thought you'd be saving a decent amount best case versus worst case. Kerbal Space Program? Venus spins in the opposite direction of Earth. When you pass in front of Mun, you will lose speed instead of gaining it. I've done it before, by accident, and seen quite clearly the "loop" my projected orbit makes around the Mun. Unless you're pretty lucky, floating point errors in the physics engine will ruin complex gravity assists even if you understand the concept and set everything up properly. While the Mun is nice and massive, I've never found it to be worthwhile as a gravity slingshot out of the Kerbin system. Smashing the maneuver node stack for fun and profit. To get even more out of a gravity assist, you can perform a powered gravity assist. To do so just do an Ike flyby. And then we come to today; I've only just finished Scott's video in which he's showing the Bepicolombo mission being played out in KSP 1.10. With the tools in the stock game, and no outside tools at all? 11:33 – I wouldn’t call Bop and Pol “practically planets in and of themselves”, given that they’re the fourth-smallest and second-smallest bodies in the entire Kerbol system, respectively (the smallest and third-smallest being Gilly and Minmus, respectively). That way your retrograde burn for both circulurization and deorbit/landing is benefiting from your vessel going against the flow of that whirlpool, gaining a natural decceleration. Because me too dumb, didn’t know about RCS… it was tedious. Your link has been automatically embedded. The 4 Directional RCS thruster now glows independently ie You thrust forwards, the nossel/s pushing you forward glow, It’s really cool 9:30 – I half heard that as “Siri analogue”. This guide does not adequately explain how gravity assists actually work. KSP has one problem with its physics engine, it is not N-body simulation, SCOTT: _”Which makes _*_landing on it_*_ a lot of _*_fun.”_* , 9:40 “I’ll save that to another encounter” almost literally. That’s a long ass time. You hard to go in the in-cockpit view and spot the radar altimeter display. I would suggest aerobraking. Thanks Scott. A gravity assist maneuver, as described here, would have almost no impact at all, if performed in a polar, or near-polar plane, even if going parallel to the body's trajectory. Is it possible to visit all of the major bodies with just a single precise insertion at the beginning of your journey? Of course, even the advice in this paragraph is reversed if the planet spins in the opposite direction. But that highlights a simple summary of gravity assists in general that even the most inexperienced player can understand. Finally, if you really want to do gravity assists instead of doing normal Hohmann orbits to save time...use the flyby finder. need more things to do in ksp, beppi-columbo just sounds like columbo’s italian cousin, love the kerbal content, love the normal content. Scott, I’ve watched your KSP videos for a very long time. To use planets for braking you need either go retrograde around the Sun, which is very impractical, or you need to have very simmilar velocities so that you can do a free "u-turn" around the planet. I didn't do that, must be a bug.". If, in your first assist, your orbit has a period that's a multiple of Jool's year, you will come right back to it ready for yet another assist! Congratulations, you are now on a trajectory set for Jool! Kerbal Space Program 1.7 Update – Epic Gravity Assistathon! Accelerate time until you left the SoI of the Mun. it shows him bouncing about but looking at it I have to say it's the only video of his in which I think he's essentially winging it, fiddling about with manoeuvre nodes until he gets an encounter with some planet, and then heading off in that direction. The gravitational pull the surface is 1.63 m/s², 8.18 m/s² less than that of Kerbin and about the surface gravity of Earth's Moon (1.624 m/s²). Maybe even a reboot of the tutorials??? Glad to see you are still doing KSP videos. Sometime’s I find it more enjoyable to watch KSP than play it for this reason. This page was last edited on 2 May 2019, at 19:58. If you can gain energy during a gravitational slingshot, it makes sense that you can do the reverse too. The only difference is you get a small (unpowered) boost from the Mun on your way out of Kerbin's SOI. For all your gaming related, space exploration needs. If, in your first assist, your orbit has a period that's a multiple of Jool's year, you will come right back to it ready for yet another assist! That’s an excellent thumbnail! Warp to the node and execute it. BOOM UPDATE, you had to lauch at the moment when the planets are in one line. I does not matter what direction a planet is moving in. KSP!!!! As the spacecraft approaches periapsis, the two become tethered together by gravity. So if anyone has a system to actually plan a mission from the ground up which included gravity assists, and not just hitting them by pure luck, I'm sure I can say I wouldn't be the only person who would like to have it explained. This is also why when you intend to circularize an orbit and land on any body in the Kerbol system, you set up your encounter to approach against the spin. The closer you get to the body, the greater the assist. I was all excited to see you explain gravity assists in detail and show how you made your timing decisions. Hum… am i the only one that knew there was a radar altimeter in the vanilla game wayyyyyy before this update? The post is coming from inside your house! As this tuturial suggests, make your intercept periapsis appear anywhere ahead of the planet or moon.
