In my previous blog entry, I found the delta-v required for an Earth-Mars in a simplified scenario. In this entry, I will discuss how to get the timing right. In the first entry, we determined the semi-major axis of our transfer orbit to be 1.885e11 m, and the standard gravitational parameter...

Most of the stock bases in Orbiter just have the marker and a landing pad with no visual element. To make them show up, I recommend the surface base upgrade mod.

I have recently taken an interest in doing the math for my orbital maneuvers in Orbiter and Kerbal Space Program by hand. I am mostly writing these down for my own reference (sorry for the sloppy disorganization), but perhaps they will be useful for someone else, so I am publishing them here...

Here are a few pictures of a lunar base I have been working on. View from a landing pad: View from above showing the layout and placeholder surface tile: View on approach to landing: The place lights up like a Christmas tree at night: What do you guys think?

Thanks for the quick response, Keithth G. Would you mind showing how to derive the equation?

I have recently been interested in doing math by hand for my flights in Orbiter. However, there is one thing that I haven't been able to find: How do I align my ejection burn so that my final velocity is tangent to my path around the Sun? For example, consider an ejection burn from Earth to...

Final score: Brazil defeat Croatia 3-1.

I'm a bagger at a grocery store that still has baggers.

NationStates rarely has action choices that I agree with fully. I'm moderate right, but the options seem to usually be [far right/conservative], [far left/liberal], [reactionist]

I'll walk you through it. deltav = g • Isp • ln(m1/m2). \Delta v = g * I_{sp} * ln(\frac{m_1}{m_2}) The tricky part of this is the ln part. I divide by g and ISP to get ln by itself. \frac{\Delta v}{g*I_{sp}} = ln(\frac{m_1}{m_2}) Here's the trick to getting rid of the ln: raise everything...

In FSX I always manage to need twice the fuel that the in-game planner says. If it says I need 1,000 lbs, I'll load 2,200 to make sure I get there. :P

Yes. If you use parts from the set, direct users to download the pieces from my download. Don't just throw them into your own download. I don't think I will do that. First, if others have modified their taxiway textures on their own, it will be reflected by the pieces the way is currently is...

All the square meshes are 1x1. Non-square pieces (like aprons and turns) have edge lengths 1, so you make them the same size as the width of the taxiway to make them fit.

What do you mean? There are no textures in the download: the pieces all use default textures that come on a clean install. Now what do you mean by subdirectories? (please excuse my incompetence) Good ideas. Maybe I should turn this into Generic Scenery Building Blocks. But for right now I...

Taxiway Building Blocks (TBB) is a set of meshes that can be used as taxiway segments. It also includes a PDF in the Doc folder that shows how to use each piece. Feel free to use these parts in your own addons, but DO NOT include them in your download package. Direct users to this page to...

Would there be any interest in a sort of "taxiway building blocks" addon? Concept:

:happybday:

Interesting troll math I found: constant of integration = 1. antiderivative of Cdx = Cx+C = C(x+1) However, C is technically a constant, so we can bring it outside the integral. C*antiderivative of dx = C*(x+C) Thus C(x+1) = C(x+C) Thus C must = 1. Since my understanding of calculus is...

Beware the ides of March. It's tomorrow.
