The Ultimate Challenge...A massive boulder...whoever beat it literally beat the game, and i'm currently into it. Here's The current Challenge Thread. Werhner finished all the Landers, he later called Simone, Jeb, and their friends to discuss about the names, and where each of them will go to in the mission. "Alright, here is The Eve Lander, it's 44 tons and will take a Kerbal to Eve surface and get to orbit with its own power from above 2100 meters ASL, who will get there and what shlould we call it ???" Werhner said. "We can't let Simone hog all the glory, we'll show him what we can do !" Said Jeb, others replied "YYYYEEEEEAAAAAHHHHH", and Simone responded "Whatev, give me a break and i'll leave everything except Eve and Tylo to you guys, i'll call it 'Grizzly Reaper'". "This is our Duna Lander, it will also Land on Vall, who wish to get there ???", Val replied "MEEEEHHHH, i'll be using that Lander all the way in this mission, i'll call it 'Vendetta' and i'll go with Duna, Ike and Vall". "This is our Moho Lander, we don't have to worry about electricity in Moho, it'll also be used around Eve system and Duna system, who wants to land it ???", Bill answered "Me, i'll land that on Moho, it'll be fun, i'll go to land on Gilly, Moho and Pol, and won't use anything but EVA pack to land on Pol, i'll call it 'Electra'". "This is the Ion Lander, it will take on Eeloo, Mun and anything smaller, who wants it ???", Simone replied "Jeb and Bob will need that, i'll call it 'Megawatt'". "Our best Laythe Lander up to date, who wants ???", Jeb replied "Yes, me, like Simone said, Bob and i'll need the Megawatt, i'll call this 'Hex' and i'll go to Dres, Eeloo and Laythe, Bob will go to Mun, Minmus and Bop". "Simone...how are you going to call your private Tylo Lander ???", Simone answered "Big Boi it is". "This is how the smaller recoverable Landers being recovered. Simone, you have my trust and you're allowed to recover The Landers" Said Werhner, which Simone agreed hesitatelessly. -Mothership : (2 Types) Mercury (Moho and everything else, has only 1 or 2 Landers attached to it, released in Eve). Joologist (Jool 5, bigger Mercury with real pods, more engines, more tanks and has 4 Landers attached to it). -Lifter : Sheep v3 Ascent Stage (AKA Chimera). Conclusion : 5 Kerbals to a WHOLE Kerbolar System Tour and back...With NO ISRU !!! Landings for each Kerbals : -Simone Kerman (9) : Eve, Tylo. (+Anziephus, Spade, Putto, Ovis, Shrek, Lotus, Duran) -Jebediah Kerman (9) : Dres, Laythe, Eeloo. (+Ebenus, Rheis, Arane, Nuu, Akel, Nuuma) -Valentina Kerman (8) : Duna, Ike, Vall. (+Pherph, Tekcate, Dhar, Vra, Dauble) -Bill Kerman (8) : Gilly, Moho, Pol. (+Epam, Oorma, Phoe, Flo, Durus) -Bob Kerman (8) : Mun, Minmus, Bop. (+Eiwei, Tekili, Tekova, Mez, Es) Status : Mission Accomplished !!!!!!

This is the first official challenge by World Space Club, and in this case it is all about Kerbal Space Program! Your goal is simple: conduct a manned Duna mission, and set up a base. Now, because not everyone is on the same skill level, competition 1 actually has multiple sub-challenges and challenge-types for you to choose from! You may enter one or more of the sub-challenges, but make sure you either film it or take photos periodically, to document your work. Once you're finished, send those photos or video links along with a brief explanation of how you did it to the email wscksp1@gmail.com and we will look at it. The best 5 submissions will be featured on the World Space Club website, and announced on social media and in our magazine Explore Space. The winners will be given a to-be-determined awesome reward of the Kerbal merch variety! The deadline for submissions is December 1st. Anyone may enter, but in keeping with World Space Club’s mission only people under 19 will be able to win. Sub-challenge 1 - Race to Duna! The first sub-challenge is simple (-ish). The director of the Kerbal Aeronautics and Space Administration has tasked you with, before this decade is out, landing at least 2 kerbals on Duna's surface and returning them safely to Kerbin! (Types can stack) Type 1 - Standard. Type 2 - Land on both Duna and it’s moon Ike. Type 3 - Bring a fleet of satellites with you and leave them around Duna. Type 4 - Bring a deployable open-top rover with you. Type 5 - Bring a pressurised rover with you. Type 6 - Do it all without using ion or nuclear engines. (Levels can stack) Level: 1 - Standard challenge, no mods. Level: 2 - Do it in career mode. Level: 3 - Use a life support mod like snacks, USI or TAC. Level: 4 - Use the Kerbalism mod. Level: 5 - Use a 2.5x scale solar system mod. Level: 6 - Use the Real Solar System mod. Level: God - Use Realism Overhaul. Sub-challenge 2 - Brave new frontier... With the successful completion of our first Duna landing, it is up to you to ensure that that mission will not be our last. Build a base on Duna that can hold 10 kerbals and keep it permanently manned, with crew rotations every two to three years. Good luck! (Types can stack) Type 1 - Standard. Type 2 - Build the base within 100km of Duna’s poles. Type 3 - Build the base with extra living space, enough for 20 kerbals. Type 4 - Also set up an orbital station around Duna with space for 5 kerbals. Type 5 - Bring long range rovers with you (range of 1,000km or more). Type 6 - Complete the base in under 10 years. Type 7 - Do it all without using ion or nuclear engines. (Levels can stack) Level: 1 - Standard challenge, no mods. Level: 2 - Do it in career mode. Level: 3 - Use a life support mod like snacks, USI or TAC. Level: 4 - Use the Kerbalism mod. Level: 5 - Use a 2.5x scale solar system mod. Level: 6 - Use the Real Solar System mod. Level: God - Use Realism Overhaul. Sub-challenge 3 - Setting up shop. Now that the first Duna base is starting to not only survive, but thrive, let’s continue by building a long range interplanetary vessel, with enough space for a crew of 20, and having it make the round trip between Kerbin and Duna every transfer window, resupplying the base. Also, have the interplanetary ship drop of additional base modules expanding the surface bases capacity to 30 kerbals. (Types can stack) Type 1 - Standard. Type 2 - Build the ship with extra living space, enough for 30 kerbals. Type 3 - Build the base with extra living space, enough for 50 kerbals. Type 4 - Also set up an orbital station around Duna with space for 15 kerbals. Type 5 - Complete the base expansions in under 20 years. Type 6 - Do it all without using ion or nuclear engines. (Levels can stack) Level: 1 - Standard challenge, no mods. Level: 2 - Do it in career mode. Level: 3 - Use a life support mod like snacks, USI or TAC. Level: 4 - Use the Kerbalism mod. Level: 5 - Use a 2.5x scale solar system mod. Level: 6 - Use the Real Solar System mod. Level: God - Use Realism Overhaul. Sub-challenge 4 - Into the Unknown... Now, thanks to you, the Kerbal Aeronautics and Space Agency has firmly established a base on Duna’s surface. It is now time for KASA to continue its exploration of the Kerbin system, by conducting a manned mission to Jool! In order to do this, you must first construct a massive ship in Duna orbit. When the time is right, that ship will break away from the bounds of Duna’s weak gravity field, and thrust itself into the outer solar system, where no kerbal has gone before! Once it reaches Jool, the crew will take a lander down to the surface of its moon Laythe and stay for a few years, before returning to the ship, and then, Kerbin. (Types can stack) Type 1 - Standard. Type 2 - Land on not only Laythe, but all of Jools other moons. Type 3 - Bring a fleet of satellites with you and leave them around Jool and its moons. Type 4 - Bring a deployable open-top rover with you. Type 5 - Bring a pressurised rover with you. Type 6 - Do it all without using ion or nuclear engines. (Levels can stack) Level: 1 - Standard challenge, no mods. Level: 2 - Do it in career mode. Level: 3 - Use a life support mod like snacks, USI or TAC. Level: 4 - Use the Kerbalism mod. Level: 5 - Use a 2.5x scale solar system mod. Level: 6 - Use the Real Solar System mod. Level: God - Use Realism Overhaul. If all of these challenges sound to difficult, then don’t worry, there is a fifth. Simply make a GIF or video under 2 minutes long of the most ridiculous, intense, over the top, or comedic explosion you can make. Whether it’s a lander falling over, a rocket plowing into the ground, or a botched docking, it wouldn’t be KSP if something didn’t blow up!

Hi and welcome to this thread! I am a big fan of the current progress LinkSpace is doing. Their NewLine-1 rocket is paving the way for reusable launch vehicles on Chinese ground. That's why I am inspired to make this mod. This is currently the dev thread of mod. Please report any bugs and features you would like to see.

As the title implies, your goal is to land on the roof of the KSC, however, this is not your every day land on the roof challenge: Tight engineering restrictions make this a true challenge, one for the can-do-all types. You have to be good not only at engineering an aircraft that fits the rules, but also have the hands required to put it where I ask you to, in the way I ask you to. You might post any attempt with any craft for fun, but competing runs must adhere to the following: Procedures & Rules: •To create a fair experience for everyone, mods are not allowed for competing runs, in any form, save for information mods like engineer. Parts, physics or skill affecting mods (such as airplane plus, FAR/NEAR or mechjeb's autopilot respectively) are definitely not allowed. Again, for clarification: NO MODS - Even if not doing so with malicious intent or even knowledge, you might be gaining advantages over all-stock entries. With the tight regulation margins of this challenge, that's something I can't allow. •Create an aircraft that meets the following criteria •Your aircraft, once built, has to take off from the default runway without any kind of assistance (towers for example), and land at the two helipads on the KSC rooftop. The flight and landing have to meet the following criteria: Lastly, to validate your entry, your aircraft must meet the following criteria after completely stopping: As you can see there's no score system, a successful landing with a craft that follows the rules is all you need. I'll probably make a badge or something to include in your signature. TL;DR - Short, precision landing competition for "standard" aircraft, except the runway is the two helipads on the roof of the VAB. Have fun. You can post entries that don't follow the rules as well, but of course they won't count. My attempt, includes F3 screen to show that nothing fell off after that little slide lol: https://streamable.com/7r7mm

On-Board Cam: Ground Tracking Cam:

Landing a first stage booster is hard, but this guide will help you with it. The picture below shows what can happen when there is an unsuccessful landing attempt. Picture above show that during landing, the rocket can run out of fuel. This picture shows when the landing attempt failed. So the rocket crashes. before we start. you need to know how to: Get to sub orbital trajectory. Get to orbital trajectory. Know how to use fast vessel switch ( using " [ " and "]" ) and map switch. ready? let's start! here i'll leave a rocket.so you can download it . https://kerbalx.com/Jeronimo/Dragco (p.s. i'm too lazy to add pics.) So now that we have an a craft. let's Begin! Ok. when it's on the launch pad. check the staging. after all stages checked (showed in the pictures below), you should launch the rocket. When you reach the speeds of around 100 m/s. start turning from ~90° (degrees) to around 80-70° Keep the throttle at maximum throttle. Note, you need to be sure that you'r sub-orbital Apoapsis doesn't go beyond 110,000 Meters. after you reach ~100,000 M above Kerbin . Put the throttle at 0 power. Switch to rocket mode view Decouple the first and the second stage. After you decoupled, press "[" or "]" to switch to the second stage. Put the throttle to the first line on the throttle-meter. Then when it reaches a safe enough distance ( 20 m above the first stage) put the throttle on full. Fly up until you reach ~230,000 m above Kerbin or more (the reason behind this is that you will need as much time for the first stage). Use fast switch (reminder "[" and "]") or map switch (click on the first stage, then click switch to) and switch to the first stage/orbital booster. After you switched, make a retrograde maneuver node, and make it on the line with the island airport (or a little further, in case of what, you can add Delta-V (short Dv) ). Use RCS. Start the maneuver burn at half the time shown. Ex. if it's showing 18s. burn at T - 9s. After the maneuver is finished, turn the orbital booster prograde. When finished turning. open the A.I.R.B.R.A.K.E.S by pressing the brake button (or "B"). When the rocket is at 70,000m above Kerbin, adjust the landing position so the end of the trajectory will be a little in front of the space center (where the Airport island is located or the water near the space center) We do several landing burns to slow down the rocket, after what we will wait until it's time to do the "suicide burn" which slows down the rocket to landing point. This part isn't going to have a lot of pictures, eyeballing will help ( in case eyeballing isn't gonna help, use landing lights, so you can see how close you are to landing, preferred to use MK1 landing lights). Next, try to eyeball the landing, here i can't give any advice except try to keep the throttle down no more than half of the throttle, so right before landing, you could put as much throttle needed to bring the rocket to full stop. Also, important, do not turn of RCS at any point in the flight after turning it on. When you land, do not turn off the RCS, until you sure that the rocket is stands stable. Result you might get. Now, when we finished landing the first stage, we go to the map, and using the map switch, we switch to the second stage. Next, we turn on the throttle on and get the second stage to orbit. Congratulations! You landed the first stage back to Kerbin, and got the Second stage into a Kerbin orbit without quicksaving. Special thanks to one and only moderator : @Vanamonde

What are your proudest moments in ksp? Mine was not eve in KSP. Mine was in Google. I typed 'Jeb' into the search bar, and -adiah Kerman was the first result.

I think I found an American landing site on the mun. It's a large obliesk with an American flag with a small lander. Anyone know the history of it, why its there? Thanks in advance :) Also to confirm finding it was an accident. I've never heard about it before, and happened to stumble across it on my second mun landing

Hello All, New to this forum and would like to suggest a challenge. So, I looked for videos of anyone that has landed on the Mun on the default "To the Mun" training/mission and couldn't find any! (share link if you know one)This one guy tried it and successfully got to the Mun but exploded on landing,... as have I multiple times now. Now, the mission may seem like quite a simple one to the more advanced players,... and it might well be. But i think maneuvering with limited fuel for the landing might present an added challenge. It could also be a great contribution for novices like me to learn from, and for the person who does it, to flaunt their awesome skills and be hailed as a hero by the community for their awesome accomplishment So without further ado, I challenge anyone to: Land the Landing Module on the default "To the Mun - Part 1" training/mission, and post a link to the video on this thread God speed and good luck!

In this thread, you can post your first ever Mun landing, your proudest Mun landing or any landing of that type. RULES: - It has to be a manned vessel. - You have to have an image. - It has to be YOUR photo and landing Listen, this thread was not made for me as no matter how hard I try, I either crash on the Mun or do not have enough fuel to return... I wish I could land on the Mun, and maybe someday I'll be able to, but for now, this thread is for the amazing Kerbal Kommunity and not me. Some people might know about my tries, such as @Orb8Ter , @Monkey Taylor and @Eveeloo , two of which have left the forums. Hope you all enjoy!

Does anyone have a table or list of calculator with the upper limits of the Delta-V require to go from say a 50-100km orbit to a safe landing. I get it wrong too often. I just landed a base segment on Minmus with literally 10 times the Delta-V it needed. I ended up just throwing away all that fuel because it was late at night and I had to get to bed. It would also help if the resource you supply me with also listed optimal acceleration figures for landings. That's been on of my problems in these 155 years too. Help me improve my game, please.

I really want to know how to decelerate efficient for landing. example, landing to mum, If I decelerate too early, my vessel will drop down, and I have to decelerate again, this will waste some fuel. If I decelerate too late, It's dangerous to crash. so, How to know, what altitude is best to decelerate can save fuel? I see MechJeb didn't have this Item that can display this information. But I use its auto landing function, I see its operation, it's good, very efficient. no more redundant action. But, I don't like auto-operation, I like to control by myself hand

I wish to land near a supply depot that I landed before on the Mun. The problem is, no matter how I try, I land some 3 kilometers away from the target. How do I land within a 100m of the target?

My stubby little plane bounces like crazy on the front wheel. I've tried numerous combinations of spring strength and dampening, and I cannot solve this. Ironically, I've had a bit better luck with the rear gear (though it is also problematic), and considering it is really oversized for this aircraft, I would assume I would have more problems with it than the medium one on the front. The video is with the front gear a 1.3 spring and .9 damper, but I have tried extremes at either end and cannot seem to tame it sufficiently. Thoughts? I realize this is a light aircraft and my approach was a little steep, but this seems a bit over the top.

**Before I start, a little about me; I've played KSP for a long time, I can't remember exactly which version, and I got into it thanks to Robbaz' YouTube series. I've restarted several playthroughs and been a part time lurker on these forums, but now that's changing. With this career I've decided to become more active, particularly with the Mission Reports and general conversations, I might even take on a few challenges within my career. In my entire time with this game I haven't left Kerbin's SOI, but again, I'd like to change that. My mission reports may be inconsistent in their formatting and style, but one thing I'll try to keep throughout is a track of the money earned from each mission (space exploration is a business, after all), and the science earned from each mission. Without further ado, here is the first instalment, landing on the Mun.** Mission Report: Year One, Day 16. ** OPERATION MUNSTRIDER ** After the successes of the Space Program thus far, the Kerbin World-Firsts Record-Keeping Society has allocated funding for the next milestone; to land on the Mun.The recent flybys and sightseeing launches have piqued interest in the planet's closest natural satellite, and it's time we landed on it and returned safely. Mission Objectives: PRIMARY - Land 3 Kerbals on Mun's surface and return them to Kerbin safely. - Gather scientific data by performing every available experiment we have currently developed; Materials Bay, Mystery Goo, Barometer, Thermometer, Surface Samples, Crew Report and EVA Report. SECONDARY -Proof of concept and test run of a reusable lander, able to land on the surface and return to orbit capable of docking with another craft for refuelling. -Plant flag for FLOOYD Dynamic Research Labs. We've been allocated a 70,560 advance in funding to develop and construct the lander and launch vehicle. The launch vehicle and lander came in a a total of 54,353. *Mission Updates* - Launch went off without a hitch, and Bob, Bill and Val settled into an 85km orbit, before burning out towards Mun. - An uneventful transfer between Kerbin and Mun, tensions began growing as Mun grew bigger. - Orbital insertion burn to Mun was nominal, and the ship settled into a 20km orbit. - Landing Sequence began, targeting the western edge of the East Farside Crater. - Bill reported concerns regarding fuel levels, we ran the numbers and there was cause for concern. - Touchdown on Mun! - Bob took samples from the crater, performed an EVA report and planted the flag as per the mission objectives. Bill inspected the craft for damages and areas of concern. Val's mental state deteriorated, Bill's concerns over the fuel pushed her into a state of panic, she refused to leave the cockpit for fear of being stranded. However, she did manage to fill out a crew report of the situation. - Bob decided to go sightseeing, being a surfer in his spare time he decided to visit a wave-like formation at the edge of the crater. Flight Control was not impressed. He retrieved a surface sample and returned to the ship, spectacularly wiping out on the way, proving the resilience of Kerbalkind and the spacesuits. **CRITICAL MISSION UPDATE** Low fuel levels, insufficient for return. Develop refuelling drone to perform orbital rendezvous in Munar orbit. Kerbin World-Firsts Record-Keeping Society provided additional contract and funding to bring the mission home. PRIMARY OBJECTIVE - Rendezvous and dock in Munar orbit, then return to Kerbin. - Val managed to get the ship into a stable 8km orbit, Flight assured them that they had a solution for their fuel shortage, and that this was part of the secondary objective, and they could use this time to gather more data from orbit. - Refuelling drone launched into orbit with no issues, sitting at 90km before launching towards Mun. - Bob performed several EVA's in orbit, setting a new record. - Refuelling drone docked with Munstrider with no issues, a testament to the capabilities of our probe technology. - Refuelling drone undocked and launched itself into the surface of Mun. **END OF CRITICAL UPDATES** - Val brought the crew home, touching down on the deserts of Kerbin. *Mission Summary* Primary Objectives. Moderate Success. Further development of lander needed, fuel issues need solving before further Mun Landings. Science returns outstanding, can use returned info to develop technologies further. Secondary Objectives. Docking capabilities adequate. Current model is unfit for re-use, development required. Flag planted for FLOOYD Dynamic Research Labs. Space Program reputation increased, public opinion tracking at a record high, funding will be more readily available, providing we can continue to push, to innovate, and inspire. **Funding Breakdown** - Initial Contract - Kerbin World-Firsts Record-Keeping Society 70,560 - Advance 332,640 - Reward -54,353 - Cost --------------------------------------------- 348,847 - Total Earned -Additional Contracts -FLOOYD Dynamic Research Labs 69,000 - Advance 191,400 - Reward ------------------------------------------------- 260,400 - Total Earned 609,247 - Running Total -Kerbin World-Firsts Record-Keeping Society 124,992 - Advance 589,248 - Reward -24,985 - Cost ========================= 1,298,502 - Total Earned Official Images:

I think that question is scientific enough, i just started Microsoft Flight Simulator and tried to fly from Okęcie, Warsaw Poland (EPWA) to Schönefeld( EDDB) i managed to fly to Berlin but failed to land, even trough programmed ILS and set autopilot into approach mode i just wonder does only i had graphic issue on MFSX Steam edition ?

Trying to land but crashed it instead

Hi everyone! I'm experiencing the following problem since the last patch has been installed (not experiencing for sure before Making History). The landing struts keep exploding even at very small velocity, in conditions they were working just fine in the past. They explode landing on the Mun or even on the launching pad. Anyone having the same issue? I've the Making History dlc installed and the custom Kerbal Engineer Redux installed (https://github.com/jrbudda/KerbalEngineer/releases). Thanks for your help!

I've often wondered what the deploy function was for on winglets and tail fins. They didn't seem to have much use at all. So I've never, ever bothered binding that function to an action group. This is my current "Science Plane" - It's got an octo for stability control - a load of science bits a couple of engines and two tail fins, the reaction wheel is not necessary, I just like it for making "on the spot" turns instead of faffing around taxiing in a circle. Its ugly but it flies pretty well and it does the job. The wing section at the front is for a kerbal to stand on when they climb out of the cockpit. As long as you are doing less than 80m/s you don't get blown off the wing. Though I wouldn't recommend "let go" or "climb out" or you will disappear into the distance which is why everything can be reset from the cockpit door - no the wing is to stand on to take surface samples when landed really. Anyway back to my point - I've always had to slow down to do EVA's in flight and to reset the science stuff. This has led me to wish I had air brakes. Today though I thought "I wonder?" so I went back to the SPH and bound the deploy function to RCS toggle because I only have basic action groups available right now. Lo and Behold a PAIR, you must have 2 or things will go very bad for you, a PAIR of fins turn in on each other and produce a massive amount of drag working just like an air brake!. This resulted in my first ever successful landing at the abandoned island air field. As you can see the tail fins are turned inward this allows me to really control my speed on approach to a runway and indeed on the runway itself to aid in braking. I would highly recommend this kind of setup (2 fins or winglets ) to anyone making planes because it's just so useful. The first deployables you get are in Aviation ( Tail Fin ) and Flight Control ( AV-8 Winglet) - Obviously you need Aviation for making planes anyway but there may be a use for deployed winglets in aerobraking maneuvers.

(Apologies in advance for opening a topic again on something that's been discussed a lot but don't want to reopen old discussions either...) Apologies also if someone has already pointed out what follows... S = 1/2 a.t^2 The concensus in the forum seems to be that the best way (no atmosphere) to take off and the most efficient way to land is expend the greatest percentage of work on the horizontal velocity component to either establish or eliminate orbital speed. This is in line with Newton's idea that if he could climb a high enough mountain and shoot a baseball toward the horizon at a high enough (instantaneous) speed, it would come back to hit him in the head 90 minutes later. The problems with screaming in low and fast for a landing are terrain clearance; pilot reaction time (as this will effectively be a suicide burn which is what makes it efficient); and therefore inaccuracy. I just tried this at my mining camp on Moho and touched down softly 24m from the target. (For those who religiously don't use MechJeb, leave the autopilots alone but MechJeb provides essential displays; in this case: Orbit Info; Surface Info; Vessel Info and Rendezvous Info.) I suggest the procedure is as follows: perform any desired inclination change 270 degrees before the target; lower the periapsis to a few km above the target, 180 degrees before the target; on the first attempt, use the altitude of the highest mountain as your target periapsis to avoid premature contact; watch true altitude for a minimum which will tell you how much you can lower the target periapsis on future landings; your speed will increase as you get lower which means that your orbital speed will serve only as an initial (low) approximation; Vessel Info displays your max deceleration rate. Reducing speed from 828 m/sec with a deceleration of 16.18 m/sec/sec will take 51.2 secs; S = 1/2 a.t^2 suggests that in that 51.2 secs you will travel 21.2 kilometers; when the Rendezvous Info display says you are 21.2 km from the target (or a little before if you are nervous), fire Full Astern; Using a periapsis of 6km above the target, I arrived 2km over the target and a little after the target (because I got distracted and fired late). And vertical and horizontal speed zeroed out approximately together, which is what you'd expect from retrograde. (The MSA for this approach is actually around 5.1km, so I possibly can tune this down near 1.1 km above target.) You exit suicide burn at this time or a little earlier, when your confidence is ready. Then fly the navball in what is pretty close to a short vertical descent. The reputation is that this low, screaming approach is inaccurate, but if you are avoiding terrain anyway, it adds up to "landing" (arrival) a kilometer above the target and then a short walk in the park to get down and dusted off. The hard part is knowing when to fire and this is where the equation above is your friend. A quick manipulation of that equation gives you the following: S = 1/2 v^2/a S = 1/2 828*828/16.18 = 21.186 km (If there's enough interest, I'll make a video.)

Hi everyone, I'm trying to figure out what is the most efficient way, fuel-wise, of landing on a celestial body. What are the equations that I must plug my values in? What is the T value that I should start retrograde burning so that just when I'm going to touch base I'll have a velocity of 1 m/s or so? How to figure out this physics problem?

Does anyone know where I can find the exact dimensions of Falcon 9's Fairing, Stage2, interstage, Stage1, and dragon? I'm trying to build a perfect replica in RO

Hello, and this is my first post here! I hope this is not too much of a noob question, but is there anything like a VOR to help landing an aircraft, SSTO, or shuttle? If there is then I missed it, if there isn't then what else can I use to help make landing a bit easier? Is that too many questions? Any and all advice will be gratefully accepted. It is needed. Thanks you in advance, but I must attend to my clockwork band.
