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.
At the time the photos were taken, both spacecraft were about 26 kilometers or 14 nautical miles or 85,000 ft above the surface, with a horizontal velocity of 1.6 km/s or 5,350 ft/s! So the distance to the ground against the distance "down" to the CSM was way higher (as you suggested).
The...
Yep, agreed, indeed some great images there!
@JEL: That photos were taken by Cdr. Gene Cernan from the LM Challenger, just one revolution prior the landing. Undocking of the LM and CSM happened only less than a quarter orbit earlier (~30 min.). During the undocking phase, the LM was...
Jarmonik, thank you already for looking into the atmospheric scattering subject. I very much hope that the information from Eric Bruneton is something you can "translate" (sort of) into your D3D9 Client. That would be so unspeakable awesome...:thumbup: In my opinion, Mr. Bruneton's work is...
Hello Jarmo,
I am not sure if it has been reported before (I don't think so), nor if it is only an issue on my end, but it seems the ambient light level is fixed to a minimum > 0. When I set the ambient light level to "0" in the launch pad, I still notice a dim ambient lighting level. I noticed...
Hello Jarmo,
just now as you have been looking closer into the atmospheric rendering, may I suggest you may take a look at the stunning work of Eric Bruneton? In my humble opinion, he's created the most realistic looking real-time atmospheric rendering I have ever seen...
I concur with all being said above.
Also from my side, THANK YOU, Leslie, for everything. I loved all your movies and your dry humor.
The world is a less funny place now.
Hm, I highly doubt there's any engine control related switches on the outer right edge of the main panel. He's merely reaching for a handhold or grip on the right. IMHO.
One thing though, I would not have clapped my hands as early as the GOTR (guy on the right) started doing. I mean, the moment...
Right. So if this actually was a missile climbing steeply into the sky, then please explain why the trail is lit by the same red sunset color from "bottom to the top"? Even if it only climbed a few thousand meters, you would see a change in the color pattern, as it would rise into (continously)...
I have to disagree strongly here, Urwumpe. Rare occasion.. :)
This is definitely an airliner. It is flying level at cruise altitude and is approaching from far distance (horizon), giving the impression of something going up. However it is simply getting closer. Contrails on airliners can be...
Wow, even NORAD was looking into this. Amazing. Maybe they should check recent flights on flightaware.com
Looks nothing else like an approaching airliner to me, flying at cruise altitude, trailing a large contrail, which is getting displaced by different high altitude winds at the more distant...
Here, Orbiter quits as it should (going back to the launchpad), however when restarting the simulation right out of the launch pad again from current state, I get an error messge and subsequent CTD.
Great work Jarmo! The quick fix you posted above did it for me. Before that, I had issues with the solar panels on Thorton's ISS, looking good now.
Two observations: distance fog does not seem to work for me, also the horizon haze looks "inverse". It darkens the sky color towards the...
Hallole,
ein wirklich sehr seltenes Ereignis. Neil Armstrong ist im Rahmen seines 80. Geburtstages diese Tage bei der österreichischen Fernsehsendung "Talk im Hangar 7" aufgetreten. Der sonst sehr medienscheue Neil trifft auch auf seinen damaligen Rivalen und heutigen Freund, Alexej Leonov...
