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.
Also the IMFD Full Manual has been posted on OrbiterWiki:

This is in the Rocket Science For Amateurs section. These resources are begging for knowledgeable Orbinauts to update them. Please help if you can!
Welcome back, talavar.
Unfortunately, I can't answer your question. However, I'd like to remind folks reading this thread that the IMFD Full Manual is available online in the OrbiterWiki at:

Also the latest updates to "Go Play In Space" are also in...
I've been around for a while, residing in Maryland, USA. But this week I've moved to the Seattle area, to be closer to granddaughter (and her parents).
I'd be interested in any Orbiter-related activities in the area, especially at the Museum of Flight.
I use Default, but not by default. I tried them all a long time ago, and re-tried them just now, and prefer the default theme (which looks like White Pages to me). But if the site admins switch to a different default, I'm willing to consider it. I prefer a light theme. Also blue-ish.
I've never seen this thread before - very interesting.
The photo below is not mine, but was made in 1931. The original print is in my possession and is about 34 inches wide (over 87 cm). I scanned it at 300 pixels/inch, but downscaled it by 10x to keep it a manageable size for this post. The...

ramjet or scramjet ?
Next to last paragraph has: "By the third launch, they had a working scramjet missile propulsion unit."
I assume this is a simple mistake, and the author meant "ramjet", as elsewhere in the article (12 times).
I hope his work isn't permanently gone. One of my back-burner projects has been to edit and post his work to the Rocket Science For Amateurs section of OrbiterWiki. Of course, I haven't been saving his posts as they came up, assuming I could get them whenever I wanted. :(
This isn't directly related to Orbiter, but some orbinauts might find interesting software in NASA's latest (2017-2018) edition of their software catalog: https://software.nasa.gov
MAVEN doesn't have a traditional camera, but can take images with its Imaging Ultraviolet Spectrograph. Here are some images:

Jason Davis at the Planetary Society is a journalist, and has issues with the lack of transparency of SpaceX's public relations operation. He has a relevant article about why SpaceX won't deliver on this announced flight schedule...
Is the Moon clearly in orbit around a larger planetary body? Or is the Earth-Moon pair two planets in a nearly common orbit around the Sun? After all, the Moon is well outside the Earth's sphere-of-influence (SOI), as Orbiter constantly shows us on lunar flights.
Take a look at this diagram of...
Habitable tidally locked?
According to https://en.wikipedia.org/wiki/Circumstellar_habitable_zone, the notion of the "habitable zone" is based on "sufficient atmospheric pressure". For tidally-locked planets it seems this assumption is unlikely to apply. Wouldn't the dark (cold) side freeze out...
