Hello, this asteroid which has been discovered on 27 December 2024, will hopefully flyby earth very close, but acutal there is a 1 in 77 chance that it hit earth on 22 December 2032. This might be the highest value since a long time... Today it has been rated 3 on the Torino scale...

Hello, I downloaded Orbiter Beta R90, but it will not start after selecting a scenario from the Launchpad. I haven't installed any addons and cannot find something in the log. I tested several 3D devices including RGB emulation, but it's still not launching, only the loading screen is displayed...

Hello I have one question regarding visual studio: I cannot find out were those $(ConfigDir) variables are set. How can I modify them if they are wrong? I've searched through the project files but can't find them and even in this view they cannot be edited...

Hello, is there a more or less simple way to get the altitude of an orbit for a given number of seconds from now from the orbital elements from the Orbiter API?

Hi one question: When V0 - Speed relativ to given point s - distance to a given point a - constant acceleration, (positiv, negativ or 0) are given, how can I calculate the time to pass the point in a common formula? I have found the formula but I don't guess it's corect for this case because...

Hello after a few years I started to continue some projects for Orbiter. But I'm a bit out from my thoughts years ago and cannot remember all the staff so I have some questions: First of all I want to remove some "Bug" I did using quaternions so I guess I builded them wrong and corrected somhow...

50 years ago, Apollo 13 lifted off from the Cape. Apollo 13 has shown us how it is possible to manage a crisis. We need more of such experts as well today, no more stupid politcans please! :)

Hello, is it possible to calculate I1, I2, I3 and I4 assumed that the resistance of the wires is negligible small (let's say they are superconductors :lol:)? Let's say voltage is 12V if required. Sorry but I don't get it at the moment...

Hello, I've read an article that Microsoft will release a new version of Microsoft Flight Simulator in 2020? I have no Idea if it can keep up with the old version in terms of realism etc., I just have read this short articles and this trailer... The graphics looks great!

Hello, i want to parse a connected char array to an array of strings. In the char array, '\0' is used to seperate the string. After the '\0' is a number, in this case 456. The problem is that \0456 will be replaced by the assci sign 456. So how I can initialize the char array right instead of...

Hello, I tried to use the scenario "Apollo 11 - 12 - Before PDI T+102h28min.scn", and there is this "CLR" Button blinking but if I press it, nothing happent... Is there something still wrong with the scenario or what I have to do? If there is any guide in the folders please let me know I don't...

Hello, is there a way to get the standard autopilots (prograte / retrograte / nominal +/- ...) working?

Hello, I have this question since some years so I will ask now: How does the flightpath looks, from a (let's say ~circular) lunar orbit to landing with v almost 0 at the end, for a ~100% fuel optimized lunar landing? (Le't ignore terrain etc. in the first step) And what's the "optimal"...

Hi, I did it and I've bought a new board and processor etc. to upgrate my PC. Now I have a strange behavior: With the on board graphic card, the pc has rebooted always in a loop. After disconnecting the SATA controller, I was able to enter the bios. When I pushed my graphic card onto...

I've got this method in my code to get the reqired vertical acceleration for landing for my baseland autopilot, but I can't remember what k1 and k2 are...? Are this values good? The code is working well, but I'm not sure how i came to this values and this formular... :-( I hope it's possible to...

Hello, today I did a quick IQ test and I had a question: In one image, there was a wall with a hole with a pattern like this: *= = - = = = - - = = = *= = - - = = = = - - = = *= - - - = = ... And now the question was, how many bricks are necessary to close the wall... My first (and right for...
