Things aren't going so well on the Trigonometry front, the Arithmetic problems are heating up. Supreme High Command is reallocating resources for an evacuation of a planet being overrun by rational numbers of great quantity!
Here's your quick briefing... Take a fighter that's quick enough to evade but stout enough to avoid any damage from variable parameters aimed at your fuselage. You'll load up with civilians, and rendezvous with the rest of the fleet. Your encrypted instructions will be a posted shortly after you accept this mission... Oh, don't forget to accept the mission.
...It's kind of a mathematical poker-run, don't deplete your fuel. BD is quite far but we wouldn't send you to infinity and beyond... because that would be redundant... and maybe copyright infringement. Now, load those Math fighters, and get out of here pilot! 🤨
In the figure below AB and CD are perpendicular to BC and the size of angle ACB is 31°. Find the length of segment BD.
First pilot to deliver a correct length of BD in light years, will recieve a Gold award on his answer post. This transmission will self-destruct in 24 hrs. if it goes unanswered. Thanks.
I’m new to the game and am doing a contract where I need to haul a liquid fuel engine into an “escape trajectory” of Kerbin. Does this mean I need to escape Kerbin’s atmosphere, or does it mean I have to escape it’s gravitational pull?
Okay, this may be entirely obvious to most of you, but I cant seem to get it through my thick head. I promise I won't be offended if you "Explain like I'm five."
From a stable orbit of Kerbin, I burn perpendicular toward the Mun at the appropriate time for an encounter. If I choose not to land (pronounced "crash"), I am now in an elliptical orbit around Kerbin and the Mun. I'm assuming that elliptical orbit will remain "centered" on the two bodies until such a time as the Mun moves beyond the current center line of apoapsis/periapsis (line of apsides?). And assuming I don't smack into the Mun on one of my orbits as it moves, LOL, I'll continue on that elliptical path indefinitely. All good, I got that. However, when I burn perpendicular to Kerbin, toward Kerbol, once I leave Kerbin's SOI, I am now in a circular orbit around Kerbol?? What happened to my elliptical orbit? Why/How did my apoapsis jump to the other side of the Kerbol system and my orbit become circular?
As the title says, I'm having issues being able to re-enter into Kerbins orbit after going on an escape trajectory after testing a part. So, to re-enter I need to rotate the aircraft backwards, and then burn so that my orbit hits kerbin. My issue being, when I do fire up the rocket, the rocket instantly heats up and blows up some of the parts. It took me a long while figuring out how to actually get into the escape trajectory, but this is a whole new level being able to actually get back into Kerbin safely.
I'm playing on career mode.
How is it different from an orbital trajectory?
I’m assuming it’s a trajectory that escapes from an objects SOI. I have a contract that specifies an escape trajectory and I just want to be sure.
I have but it was because of a glitch. I was landing a capsule on a mission from the Mun and it just lagged out.
Pretty much described in the title lol.
Back in the day it was most efficient to gravity turn at 90 deg around 9k/10k meters. With the more modern KSP it seems that aerodynamics are way more in effect than they previously were.
What's you guys' opinion on the most efficient way to get to orbit?
This is a post about the math I have derived using Orbital Mechanics equations and Trig. I wanted to share with you guys to do some checking and also in case anyone else wanted to use this.
The goal of this is to get the ship into an escape trajectory (leaves the SOI of the current body). Upon exiting, the velocity vector of the ship needs to be parallel to the velocity vector of its current body.
The input will be a delta speed. Negative delta speed means I exit the SOI going slower than the body you just left, and vice versa. The delta speed will have a minimum meaning upon exiting the SOI it will have zero speed relative to the parent body (ie Kerbin).
Where I am starting from
The body I am orbiting is assumed to be Mun or Minmus in this example, but essentially it should work from going from the SOI of your current body, to the SOI of its parent body.
Starting from a circular parking orbit who's orbital plane (or angular velocity/momentum vector) is aligned with the plane of orbit of the body I am orbiting. This is to ensure that when I exit, I will still be in the same orbital plane and thus my Longitude of Ascending Node (LAN) and Inclination will not change.
When I will ultimately perform this script the first step is to ensure that I am as circular as possible and to ensure that I am in the correct inclination and LAN (or in other words the correct orbital plane).
Important Terms
LAN - Longitude of Ascending Node: The Angular position (much like Longitude in GPS positions) of the ascending node of an orbit that crosses the reference plane of the universe measured from a reference vector. In KSP the reference plane is perpendicular to the y-axis (V(0,1,0)) and the reference vector is the Solar Prime Vector.
SMA - Semi Major Axis (variable name "a"): For elliptical orbits this is the length from the center of the ellipse to the one of the extremes along its long axis. To find this for an orbit simply take the average between the Periapsis and Apoapsis. For Hyperbolic and Parabolic orbits it is different but I will not go into them here.
FPA - Flight Path Angle (greek letter Gamma): The angle of the velocity vector with respect to the local horizon. Zero FPA means the velocity vector is perpendicular to the position vector. In a circular orbit, the FPA is always zero. The FPA is also zero at the Periapsis and Apoapsis of an eliptical orbit. General rule is if your vertical speed is positive then your FPA is positive and vice versa.

... keep reading on reddit ➡Without a manifesto, I see no reason to act. Even if I did, I could not convince anyone. While aiming for the sunfire of conviction, my words evoke nothing but a faint and fickle glow, devoid of the gravitation to pull thoughts into regular orbits. Being this way, others cannot infer the location of my core, where I truly stand.
At work, this has been a blessing. Immigration brims with ideologues of every kind. Unburdened by political opinion, I'm more often than not the sole voice of reason. Only Schmidt remains oblivious to my advice. Zealous, intrusive, toxic, his style appalls me. I don't tell him, but I'm sure he knows, has seen it every time our eyes meet only for mine to forfeit.
At home, lacking a core is not much different from lacking a spine. Margrethe doesn't show, but she must be disappointed by the sheer weightlessness of my soul. Our homemade hostage situation never triggered the Stockholm syndrome we had hoped for, and we both know who is to blame. But there is something still more gnawing to conclude: When I, despite my intimate knowledge of her mind's back-doors and secret passageways, fail to make my point, I could be erring. I could be mad.
Schmidt seems surprised to find me in his office. Not recalling why I went to see him, the words won't come, my mouth refuses to open, fear escapes through my pores. He comes awkwardly close and looks visibly worried. My arms extend and close the door as if to discourage him from leaving, or from calling for help. Unwilling to alarm him further, I try to collect myself, but he mistakes my forced look for a sign of pain and wants me to sit. I just cling to his arm like a child, nearly throwing him off balance. Suddenly a rush of adrenaline enters my bloodstream. I draw him closer and he can't resist the element of surprise. Unable to escape, he has no choice but to follow my every move, if only not to damage the one thing that prevents his soul from leaking back into the environment. His rapid heartbeat through the layers of flesh and cloth between us, the rise and fall of his breath, the scent of adrenaline, for a moment, I feel nothing but tenderness for this frail human creature. I want to kiss his neck, but lacking practice, I end up sucking it in an unnatural way.
I escape from the office, leaving my belongings behind, abandoned, to be found and thrown out by the next soul incarcerated in my cubicle. Eyes burning, vision blurred, I stumble into the parking lot, unsure what to do next.

So I got a mission to use a decouple while on an escape trajectory on Kerbal, I made it to like 1500m/s, but someone on steam said that not fast enough, and that I just need more boosters?? how fast do I need to go?
