ORBITER-FORUM will be temporarily closed at 2026-07-23 18:00 UTC while we complete some OF maintenance tasks. The amount of downtime is expected to take up to one hour, but probably less.
The plan is to transport as many standard AIA containers to Olympus Base as possible and return to KSC without refueling along the way. I've chosen a trajectory from NASA's Trajectory Browser in the near future optimizing for duration (lowest). Here's a screenshot of the plan...
When I launch the default 'Landed at Brighton Beach' scenario of the XR5 vessel and take-off for a flight to Earth using a direct entry, I arrive in the middle of the night at Cape Canaveral. Also, it's always a bit of a surprise whether I end up approaching from the north or south. I am using...
Hello,
For my DIY smart lighting system, I am downloading data from https://sunrise-sunset.org/api once a day to get various timestamps for nautical dawn, sunrise, solar noon etc. for my location.
This API is bugged in some situations. Also, it's my only dependency on the internet which I like...
In 2008, a boat that had broken down on the Markermeer lake around six miles north-east of Amsterdam dropped anchor while waiting for rescuers. When they pulled it up, they found a piece of aircraft machinery attached.
The piece was given to Johan Graas who's curiosity for aircraft recovery...
Hello all,
For a fun project (my smart lighting), I am looking for a function which outputs the azimuth and elevation along with the associated timestamps of an earth-orbiting object at a given location on earth.
Much like the info on https://www.heavens-above.com/. Unfortunately, they never...
Here's a little bug I've noticed a while ago. I doesn't really bother me but I might as well report it.
When flying inverted at exactly -180 degrees roll, if you use the 'sync' feature of the autopilot, it doesn't recognize the minus. If you roll over to -175 degrees, there's no problem. But at...
1000 lightyears that is. The previous closest one was V616 Monocerotis at 2800 lightyears. I assume the radius of the event horizon is the same as other 4 solar mass black holes, which would be almost 12km.
Here's a translation from the local media:
Today at ~14:45 (GMT+2) there was a ball of fire visible above The Netherlands, followed by reports from England, Germany and Denmark.
This is the second ball of fire in 2.5 months time. That's unusual.

Yesterday I finally upgraded to Win10 from Win81. I also updated the driver for my graphics card (GeForce 950M). The process wasn't entirely without troube, so I am unsure how stable my system is at the moment. Everything appears to be normal.
But since then, when launching Orbiter 2016, the...
To plan my flights to Mars, I am using IMFD. This MFD requires a depart and an arrival date to provide a solution for the interplanetart transfer. To minimize fuel consumption, I am doing direct reentries without entering a parking orbit.
Sometimes, the periapsis happens to be close to Olympus...
Three months. That was the original plan for Opportunity to explore the red planet. It turned out to be fifteen years. But all good things must have an end. After eight months of radio silence, people expect that NASA will declare the end of this mission later today...
For my scenario tooling, I want to calculate meaningful numbers for AROT so the scenario will start with the vessel oriented in a predifined orientation. As a start, I want to be able to calculate the numbers I need to orient the vessel prograde for any given orbit.
I have spent quite a bit of...
I am trying to create a planet for Orbiter. Actually, it's going to be an asteroid, but I assume the implementation of asteroids is no different than planets. I decided to use asteroid Bennu as an example.
Currently, the relevant part of my cfg file looks like:
; === Planetary Mean Orbits ===...
Hello all,
I would like some help with IMFD's Surface Launch Program.
The trajectory I am trying to set up comes from NASA's trajectory browser. It's a 192-day trip to Mars. Departe MJD (TMI burn) is 59064.5. Arrival MJD is 59256.5.
In the left MFD, I select the Mars and set these MJD's up in...
Hello all,
For the add-on I am working on, I would like some help or advice on Orbiter's mesh file format.
The plan is to create meshes on the fly for any asteroid in the Asterank database for use in Orbiter 2016. Since my application is running on Google Apps Script, I did have a look at some...
Dutch entrepreneur Frits van Eerd, sponsor of Max Verstappen, bought two Spitfires, a Mk.16 and a LFVIII. One of these Spits, the TB885, flew in 1945 with 322 Dutch suqadron of the RAF. The Spitfires crossed the channel in secrecy on the 15th of september this year and stayed overnight in...
Hello,
My Orbiter root folder contains a Html\Scenarios\Default subfolder.
When I create a html document with instructions for a scenario, the html is shown in the tab area on the launchpad, as expected.
I like to have this html file available in-game.
But it seems this html cannot be shown...
