Btw, if you're trying to get to a planet without any other planet between you and this planet (like a landing), instead of making a collision trajectory, when you do your reverse burn at your periapsis, as soon as you see the trajectory go behind you your in orbit, now immediately stop your engines, with enough reaction time your orbit could be very far and like 20m/s, which then a single ion engine could quickly do the job, where you would put your orbit into the atmosphere. Thats because the atmosphere will alter your orbit to be way more down, so if you are doing Venus or Earth I would go 7-10km from terrain, mars 3km, and Mercury 0km because very very very thin atmosphere
Because planets to not spin and only orbit, you should be able to just wait until earth is in the closest point to the right side of your screen (east of orbit), and then power your engines until it gets its periapsis to mercury's trajectory then wait a couple years. Its basically copying a reverse burn
Thank you so much buddy, I’ve been playing SFS for years now and still haven’t figure out how to use gravity assistant transfer, and it feels really weird when I’m trying to send Voyager 2 out to Jupiter while installing an engine on it😂😂😂
gravity assist is basically a flyby, instead of orbitting the planet, you just fly around it and back into outer space. there are two gravity assist types, one where the planet slings you closer (reduces your velocity) and one where the planet slings you away (speeds you up). You can use the first one to slow yourself down to get to mercury, while you can use the second one to get to farther planets. An example of a gravity assist would be, imagine you have a custom solar system with neptune in it. It takes a ton of fuel to go to neptune. A simple way would be to get a gravity assist from the moon, and again from earth, to slingshot yourself to jupiter's orbit. From there, you can get a jupiter gravity assist which will sling you out of the solar system. You can then navigate to uranus or saturn and then burn until you get enough speed to slow down, and get to neptune. Hope this made you understand!
I suck at using gravity assist so I can only do one venus flyby without messing up the orbit but I managed to land on mercury and even did a roundtrip by sending fuel tanks and refueling in earth and venus orbit.
Hello there. This is very useful but I couldn’t get it to work. Whenever I did it the change in orbit is minuscule. Does anyone know what I could be doing wrong.😭
@@slicerthe84th it’s been a long time since I played this game but you need multiple gravity assists to get in and out of venus. My rocket took up the whole screen. You need to transfer fuel from tank to tank. Other than that it’s pretty normal.
i transferred directly so ye i used a shit ton pf fuel and had to add extension tanks for extra fuels as manned mission to mercury also u hurt my brain just by dumping the 2nd stage that has 50% of freaking usable fuel edit: i landed the duee on mercury and sent a probe with like 5 extra tanks attached to it so enough fuel to go bacc
Venus is about the same size as earth so the gravity is about the same so that means you’ll basically get the same heat as earth but also Venus is the hottest planet in the solar system so you might just run up on your way in there I don’t know what happened to the land on Venus I’m trying to land on the moon
@@jetpond7904 not needed, basically 3 stages. First has MASSIVE amounts of fuel and thrust. Second has good amount of fuel and low thrust(use this to get gravity assists, only 2 is needed) and last stage has 15 ton take + lander can make it all the way back to earth.
I got a craft into Mercury's Orbit but it cost a ton of flue the rocket I made could send 134 tons to Leo but I was I was only able to bring 4 tons to Mercury's orbit
Wait is it possible to make a satellite orbiting the the solar system between mars and venus and make fuel tanks refuel there and then land on Mercury?
@@catscraft1620 I did the same. Built a space refueling station orbiting earth, and built another one orbiting venus. Landed on both Venus and Mercury, and could return to earth due to those stations.
Just enter something’s sphere of influence and correct the flyby And then just escape the sphere of influence and you’re done For example pretend you’re going to Venus. You just standardly do what you do to get to Venus, make a flyby with a somewhat low periapsis. And then leave it like that and escape the planet’s system. Then you have an orbit around the sun alike to venus so it saves fuel.
How did you make a design to your rocket? Like how did you add letters and things also the bottom of the rocket in the thumbnail is really cool (the landing thing )
Thank you or making this! I have landed rovers on Mars and Venus but I haven't even managed to orbit Mercury! I literally made a plan to make refueling stations all over the solar system so that I can get there but then thankfully I finally thought that I could try a gravity assist, so yeah you probably just saved me a couple of days of launching rockets lol
I had to design a rocket that could even get me into Mercury's orbit (without the expansion) and I could barely get a satellite to orbit Mercury. I thought I was doing something wrong because of how much fuel I needed
This is the way I actually landed on mercury for the first time. I couldn't get enough fuel in the lander, and I always ended up crashing because I was going too fast ( because I couldn't slow down, because I didn't have fuel ) . So I decided to experiment with gravity assists and it worked!
