Is the following way the correct way to calculate the exact crash site of a spacecraft on an airless, non-rotating, perfectly spherical body? It is assumed that the spacecraft is travelling on an elliptical orbit with periapsis within the periphery of the planetary sphere, e.g. under the surface. I write down the equation of the sphere (x^2+y^2+z^2=r(Planet)) and the equation of the inclined orbital ellipse, combine both into an equation system, solve it, select the solution appropriate for the orbital direction (because there are 2 crash points, depending on whether the spacecraft is orbiting clockwise or anticlockwise) and transfer it into spherical coordinates for latitude and longitude. Alternatively, I do the same but two-dimensionally (circle + ellipse equation) and break down the coordinates to account for inclination after calculating the crash site.

There is an increasing trend of using flyby maneuvers like in real life, but there also is the everlasting tradition of the grand tour in Kerbal Space Program. I have decided to make a little feasibility study/challenge which combines both concepts in an interesting way. Your tasks are: 1. Prove that it is possible to plot a trajectory that passes through the SOI's of all stock (all OPM/Real Solar System/planet pack of your specification) planets without midcourse corrections. Only a single Kerbin ejection burn may be made, it's about gravity assists from then on. You must change the maximum number of patched conics iterations in the settings file in order to plan the flight. I don't care if you use HyperEdit because I want to see if it is possible at all. It is especially interesting if you have Principia installed. It is enough if every planet is approached a single time, e.g. no return to Kerbin is required. However, I think that multiple flyby maneuvers of the same planet may be needed. You do not need to execute the mission, I only need to see the picture of the trajectory. 2. Document the trajectory in full detail - tell me the exact date, phase angle and DV of the ejection burn and the order of the gravity assists as well as the respective flyby periapses if you can. Also tell me the duration of the mission if you can. Good luck!

If I recall correctly, Kerbal Flyby Finder and similar programs let you specify a reasonable amount of planets to be flied by. 2-3 should be okay for plotting a course, but a flyby-only grand tour would be extremely hard.

Post anything that stays on the ground when the rocket is launched here. Be it an intricate launch tower with elevators or a bus for transporting kerbonauts to the launch site, anything goes.

Back in .14 and .15, it was somewhat popular to use jet-powered boosters on normal, expendable vertical launch vehicles. They would be decoupled upon suffocation, at 20 to 25k. Do people still do this now? The main advantage would be their reusability and higher efficiency as well as a longer burn time that varies with the steepness of the launch trajectory, the main disadvantage would be the rapid thrust falloff or asymmetrical burnouts that can lead to loss of control as well as the wasting of fuel.

I have the following problem: as the thrust is uneven due to the system’s natural asymmetry, I had to tilt the SSME’s away from the tank/booster stack. That’s what they do in real life. The shuttle now flies “properly” without becoming unresponsive halfway through ascent like most of my earlier designs. However, at launch the shuttle does not fly directly upwards but rather sideways because the tilted Vectors generate perpendicular thrust. This means that I have to do an ugly correction maneuver in the first seconds of flight and lose a lot of fuel. I have thought of tilting the whole shuttle on the launchpad, but that would be quite unrealistic. I’ll have to see how it behaves when there is a payload in the cargo bay, maybe it could serve as some sort of a counterweight. But how can I negate this perpendicular thrust? I have already tilted the boosters themselves by 2-3 degrees. Maybe I could move them further “downward” on the tank to move the CoT and change the DoT? Or should I add additional, smaller boosters that fire for 20 seconds and keep my shuttle from moving in the wrong direction until it is tilted down enough for the thrust discrepancy to be unimportant? Yes, I already tried limiting the thrust of the main engines, but this would give the whole thing a TWR under 1. FYI: The boosters are 1.25m ones from NovaPunch, scaled to 1.4m by TweakScale.

I vaguely remember a botched munar takeoff several years ago. The lander ran out of fuel, so Jeb got out and tried to achieve orbit using his EVA pack. As this failed, I decided to use the orbital module for a suicidal maneuver in which it deorbited and tried to catch up with Jeb. Turns out that there was not enough time for a clean rendezvous and/or the thrust of the lander was too small, resulting in Munar regolith-assisted, surface contact rapid self-disassembly.

A munar flyby can be used to reduce the delta-V requirement of an interplanetary answer and makes Jeb happy, especially if it is very low and. Can anybody share their experiences with flybys during Kerbin departure or arrival?

Sorry if this has already been asked or is an idiotic question, but can this somehow be used with RSS?

XB-70 was a Military airplane. Anybody who flew in it kept their mouths shut.

He was not the first person to visit Agartha. The Germans did so, even before Byrd. They even had a small submarine base, if I recall correctly. However, they left Agartha in 1944. A Kriegsmarine map from 1942 showing the Antarctic entrance. My granddad used a similar one for the North Pole. He got it from a German pilot whom he shot down over England; they became friends after the war. And you did not see the hole because the North Pole is a no-fly area and no plane goes over 82 degrees northern latitude. Anybody who sees one of the holes (military pilots, polar researchers or astronauts) are not allowed to speak about it.

By "85 degrees northern latitude", I mean the latitude OVERGROUND at which the curvature starts. The latitude underground can be calculated using various reference points such as mountain ranges that are on the opposite side of the inner surface. Why are you not taking me seriously? Morlocks are a fictional construct and have nothing to do with the Hollow Earth. What I am telling you is non-fictional.

http://www.fractalfield.com/zeitlin/EndEnchantment/Secret3.html Actually, turns out that he is calling the Inner Earth Salim. Never told me for some reason...we only spoke of Agartha, Hollow or Inner Earth. I will ask him why he renamed it. Note that he claims to be in contact with Reptilians while my grandfather even denied their existence.

The site is owned by a friend of mine. I did most of the renders there. And yes, the correct name of Inner Earth is Agartha. Neither I nor my Grandfather ever heard of the term "Salem" for that.

This is a render I based on the photo several years ago. I forgot about it. Thank you for finding it!

I am not roleplaying. I am just telling you what my grandfather told me.

The polar holes allow for air exchange and the expulsion of excess energy. My grandfather noticed how it started getting warmer and warmer when he passed 85 degrees of northern latitude. Roughly at the same time, the gravity anomalies began and his compass started spinning wildly. The Inner Earth civilizations (there are 7 of them) also employ volcanoes as heat sinks; if it gets too hot, the inner temperature and pressure is decreased using a major eruption. Krakatoa, for example.

Yes, I know the Shell Theorem. According to my Grandfather, the "inner sun" not only radiates enough heat and light for life to function but also has a "repulsor field" that utilizes "semi-psionic energy" and generates approximately (-)0.3G on the inner surface. The centrifugal force in the "equatorial" regions is negligible. And the picture: I know it is bad, but the line on the upper right is clearly recognizable as some sort of coast, top hard and straight for a cloud formation.

There are major holes at the poles with sides covered in water, allowing for planes or ships to pass into Agartha, albeit experiencing strange anomalies such as a period of near-zero-G. This is what my grandfather said.

I asked them for a contact to their legal team. They ignored my request. Note that my legal threat is fake and for fun, of course. Testing ROBLOX bots and badmins.

In 1952, my grandfather and several of his mates decided to follow the footsteps of Admiral Byrd (whom they knew) and flew to the North Pole in a decommissioned bomber. They claim that they found a hole that leads to Hollow Earth there; they entered it and were contacted by the residents of Hollow Earth. They flew for several hours before they landed in an Agarthan city, where they spent three days. When they returned, their friends noticed that they somewhat grew taller during the expedition and their clothes glowed in the night for several weeks. My grandfather (who piloted the plane most of the time) took this picture several hours after passing through the polar hole. Even though the quality is bad, a tundra landscape and the further away parts of the Inner Earth can be seen in the background. There is a river in the right part of the picture; my grandfather claimed that it was over a kilometer thick. My granddad often saw UFO's, especially silver discs, after his expedition. He even told me that he was abducted once and talked to Grey-like figures about his trip to Agartha. While he was visiting our house, we also noticed strange things; I saw unnatural lights during a late night barbecue on his birthday, for example. My grandfather went missing five years ago. The last message he sent me was the following: "They are taking me to them now. I will return to Agartha now as I promised sixty years ago. Seek the truth, my dearest grandson." Note that he never drank a single drop in his life and stayed entirely healthy until his disappearance. He even beat my father in a foot race once. Our doctor even commended him that he was as healthy as a 40-year-old at the age of 96. What do you think?

I sent them a legal threat. It was ignored.

I think it'll be a bot answer anyway. A random algorithm chooses 2% of the appeals to be accepted, maybe.

Sent them an appeal telling that it was my brother who declared that he had taken David Baszucki hostage. Hope they'll consider it 'cause I'm lifetime OBC.

I hear Jeb calling for MOAR BOOSTERS. I will build a monster only powered by SRB's. Lots of SRB's. In RO + RSS. It'll fly from Florida to Europe or from Kourou to Africa. Yes, in RSS, but in Kerbal, crashtastic makeshift style.
