zw_45 Posted March 12 Share Posted March 12 (edited) Some issues about the OGO satellite. According to this figure on NASA documentary, the experiment boom 2 and 3 on OGO should be UHF and VHF antenna. I checked the NSSDC webpage, the charged particle experiments (on boom 3 in game) was done on the forward experiment boom, and the probe does not have gravity experiment (on boom 4 in game) onboard. However, it has a trapped radiation experiment on one of the OPEP. https://nssdc.gsfc.nasa.gov/nmc/spacecraft/displayExperiment.action?spacecraftId=1966-049A Edited March 12 by zw_45 Quote Link to comment Share on other sites More sharing options...

By the way, the earliest version of the MA-1 powerplant that flew on the first three Atlas A test flights (Atlas 4A June 1957, Atlas 6A in September 1957, and Atlas 12A in December, 1957) actually had cone-shaped nozzles for the two booster engines. The first two flights ended in failure, but 12A succeeded in flying a 600nm flight. As part of the crash engineering troubleshooting process following the first two failures, Rocketdyne shifted to bell-shaped nozzles, but they were not ready for the 12A flight. Atlas 10A flew successfully on January 10, 1958, the first with bell-shaped nozzles, establishing the standard for all further Atlas flights. This was almost a SpaceX style iterative approach to rocket design. Build it, fly it, blow it up, fix it, fly it again. In this case they were doing it because they had no choice due to limited (as compared to today) ground testing capabilities and not because it was part of the Rocketdyne/Convair corporate mantra. Just a historical FYI for everyone, don't spend the time redoing the nozzles. Expand Interesting, didn't know about this tbh. I've got a fair amount of Atlas A pics in my refs but none of the conical nozzles. But probably not worth doing even if I had though, if as you pointed out only a handful of flights used them.

Expand Atlas 8A at the Strategic Air Command and Aerospace Museum has conical booster nozzles, though for some reason they also stuck a sustainer engine on it for display. I agree though that it probably isn't worth doing for Atlas. Quote Link to comment Share on other sites More sharing options...

zw_45 Posted March 12 Share Posted March 12 (edited) Here’s another thing I found about probe science - the Stanford antenna on Pioneer 6 and the dipole antenna on Alouette actually function as frequency sounder to study the electron density in ionosphere. It might be appropriate to add bd_ionelec experiment to those antennas. https://nssdc.gsfc.nasa.gov/nmc/experiment/display.action?id=1965-105A-04 https://nssdc.gsfc.nasa.gov/nmc/experiment/display.action?id=1962-049A-01 Edited March 12 by zw_45 Quote Link to comment Share on other sites More sharing options...

hikerchick29 Posted March 13 Share Posted March 13 How do you get this to work with Textures Unlimited? I installed both, as well as the recolor depot, through CKAN. But the Apollo command module just shows up as a semi-reflective dull grey, even with the game's reflective settings turned up. Quote Link to comment Share on other sites More sharing options...

Expand The Atlas 1/2 stage skirt (I forget the exact part name) allows radial attachment. I've put small SRBs on it to increase liftoff TWR. You can "abuse" that by putting decouplers and huge SRBs on the skirt, followed by offsetting to move the decouplers higher on the rocket. Hold shift key while offsetting to increase the maximum allowed distance. It will look like the decouplers are connected to the tank but they are really on the skirt.

It's actually a tag that you can apply to colliders in Unity that prevents radial attachment, regardless of the attach rules for the part. I discovered it around the time of the last Atlas revamp. It felt like it was an opportunity to introduce some interesting decision making for the player - in terms of 1.875m "workhorse" rockets, you had two options. You could go for maximum single-stick performance with the balloon tank Atlas, but if you needed something more than that, you'd have to move to the less efficient Titan, which allowed for multiple cores and thus scaled more at the higher performance end.

Gupyzer0 Posted March 13 Share Posted March 13 Been making my own tech tree for a while and with the new Atlas revamp coming I guess it's time for me to split my tankage line into balloon tanks and "normal" tanks just after Thor/Jupiter tanks. If you remain in the "normal" line you'll have to work with Titan if you go Balloon then you have the chance to unlock Atlas/Centaur.
