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...

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...

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...

Is there a way to attach multiple payloads to the stock Atlantis? The stock scenarios only ever carry one at a time. Thanks! :tiphat:

Could someone help me with making multiple docking ports on a .dll vessel? Can I just use SetDockParams (pos, dir, rot) under clbkSetClassCaps multiple times? Thanks! :tiphat:

I know it is possible to launch to a target inclination from a target launch site. Suppose I want to do the opposite. I want to launch into an orbit with a specifc LAN from a specific launch site, inclination irrelevant. Is there a formula for this? Does the problem simplify if the ascending...

My searches have yielded nothing on this topic; Is there any inline function that returns wether a key is pressed? In a vessel I am working on, it would be nice to be able to do MyVessel::clbkPostStep () { // if (KeyPressed ('a') {functions} else ; // } or similar? Looking through the API doc...

I might as well try. Psuedo-code below. UGH would be a vessel dockable to another vessel. clbkGrapplingHook (hvessel) { if (grappling hook is shot) {find object hit} else {reload grappler; continue} vessel velocity relative to grappled object = _V(0,0,0); get grappling hook vector (hvessel) =...

Does anyone else on O-F love Calvin and Hobbes? He was pretty funny. :lol:

This thread recently noted two MFDs capable of reading .txt files. I was wondering if one could be made to run console programs (.exe). It would be a nice way to link my fledgeling C++ skills and apply them to Orbiter. Simple maneuver calculators, scenario editor via MFD, grabbing data quickly...

[TL;DR, feel free to skip] I am making a simple spacecraft; so simple in fact I could make it using a config file. But I am trying to do it with a .dll, just to figure it out. Start simple. And I still can't do it. It was hand enough just getting it to build. I got a few prototype builds done...

Screw dumpsters. I'm never going to do this without some help, so... I want to make a simple .dll vessel. A simple one. One that could be done via config file. Just to get the hang of it. I sorta know what I'm doing, but then, I sorta don't in C++. So here goes. I hope Martin is okay with my...

So... A while back I tried to compile the Shuttle PB example from the Orbiter SDK, to get a grip with C++; .dll type vessels. I never did get the thing to work, and lost interest. About a month later, I decided to try again. I think I got it to work this time. (Thanks to Orb :cheers:) I set...

In short, I made a mesh for a base I am building. It was created in Wings3D using Hielor's .msh exporter. I gave it a grey color material in Wings, and exported to Orbiter. It looks fine from some angles, but from some angles it looks white. I can find no cause for this. The weirdest part is...

This isn't really a formal update, but... I added lights to Sunrise Spaceport. After looking at it, I had to ask. Is it too much? What do you think? See the attached image. Cheers :cheers:

She's starting to take shape! While some users have been critcizing a 51.6*N location, it remains there at least for now. Does anyone have any specific suggestions? The list of base objects stays the same for now: 1 -- 3 km runway facing east and west (DONE) 1 -- 3000*50 m taxiway parallel to...

E=mc^2 We're all familiar with this equation. My question is very simple: What are the units used? I'd imagine that it is in SI units (joules, kg, and c is m/s) but I want to be sure. Thanks, :tiphat:

Note; I don't plan on making daily updates. Building position randomly chosen at 115*W, 51.6*N, subject to change. I severely underestimated the size of shuttle launch pads. They have been placed 1 km east of the base marker for now. I am considering adding launch pads for other vehicles, as...

I might as well keep a log of what I do while I develop this bas(c)e. The plan is to build Sunrise Spaceport at 51.6* off of the equator, making its east/west runway most useful. It is planned to have 1 -- 3km runway 3 -- 25*50 m hangars 15 - 50*50 m hangars 2 -- 100*100 m hangars (20 in all)...

Just wondering; What are the dimensions of the space shuttle launch pad mesh? See the attached image. Thanks, :tiphat:
