  1. The Mlaj-3 apparatus opens its petals and phones home after a soft landing some 40 km west of Lindsay crater, December 1969.
  2. Say what? In most vehicles that do this, the stage starts 2-3 seconds before flameout (for Chang Zheng, the verniers are ignited 6 seconds ahead, that's the most I could find).
  3. @Phineas Freak has done a lot of work on making the mod compatible with Realism Overhaul - proper sizing, propellant usage and other things. It will be supported in the next release. As RO isn't updated to 1.2 yet and it seems you are really impatient, I suggest following this spreadsheet to manually install the needed mods, then download the RealEnginesPack compatibility patches from the RO Github repository. This should fix some of your issues.
  4. Yeah, it's easier to see from the underside They're attached to a thing procedural tank and offset, the tank itself is mounted on an IR hinge which sits on a stubby procedural wing pylon for clearance (not the same probe, but the panels are identical).
  5. @DrLicor, they come with RO as far as I know. Each wing is one large-ish fixed panel and two small ones.
  6. Pfft, this thread needs more replies. @Firemetal, how is your landing coming along? Anyway, here's Kaon: It was supposed to lift around 12 tons to low orbit, and K-mesons have approximately half the rest mass of protons, hence the name. But it actually does quite a bit more, 15.5 tons to a 65° inclined low orbit. The lower stage, block-C, has 4 NK-15 engines. I couldn't get them to fit on a 4m core, so they are arranged in a thrust structure underneath the 2m kerosene tanks. Also, they magically can gimbal (sekrit dokuments tovarischi xaxaxa). The insulated central tank is 4m across and holds liquid oxygen. The upper stage, block-L, has a single NK-19 engine burning for almost 7.5 minutes and starts out at a paltry 0.57 TWR when flying with maximum payload. Chinese-style hotstaging (the interstage remains attached to stage 1) Test payload. Roll control of stage 2 is via nitrous oxide thrusters, but they're pretty weak. As for craft files: The Kaon one is here, I think RP-0 and SovietRockets are enough for it to load. I also added two launch towers to the subassemblies folder, one with arms as seen below and the other without it to remove the IR dependency. That rocket, btw, launched the TLI stage for a crewed Moon flyby, with the Gemini launching separately. Here's the whole complex just before docking:
  7. [F]irst teaser of a hot rear end, more pics and a DL link following soon In unrelated news, I finally managed to get into orbit around Venus. With two craft, no less! Also, the most recent mission report is here in case anyone wants to read those.
  8. Good luck, and keep us posted! But a crewed Gemini capsule sips 2 kilowatts and IIRC the small panels give like 40 watts apiece when fully lit? Better double up on those batteries
  9. I for one am still on 1.1.3. But yes, the prerelease apparently works if you take some time to set it up manually Looking good! What are you using for power generation? Batteries are fine if you plan to stay on the surface for a day or two, but for longer missions fuel or solar cells would be the lighter option.
  10. The white-ish centre part of the station and Gemini capsule are from FASA, the docking ports as well as the forward set of solar panels from RaiderNick's Salyut and Soyuz mods (dunno which). Most of the other stuff is made from procedural parts and fairings.
  11. Wow, that thing is big. Impressive work on the spacecraft, too! How did your lens caps fare? Good job! Paraphrasing a certain rather famous author, half of RO's difficulties are now behind you=) Anyway, I reckon I'll spam this thread some more, here's a year-and-a-half old thing recently rebuilt for 1.1.3. Not terribly useful, but it's RP-0 stock so if anyone wants to play with it it's in my craft file folder. Eaglet Basically a small ICBM with the warhead and decoy attachment points swapped for payload interfaces.There's three of them and, oh right, no fairing. Like on a couple of Russian sea-launched missiles, everything has to fit in the last interstage. After orbital insertion, the upper stage discards its main engine and can maneuver using nose-mounted post-boost thrusters before the satellites detach. Due to proximity to the engine, they have to be covered by protective shrouds during launch, but...eh. Would've made it even more useless. Payload: 100 kg to low Sun-Synchronous orbit, ~150 kg to LEO from Wallops? GLOW: 40.0 t Cost: 24.4 million in 2017 USD. But at least the military pays for it... Upper stage after engine ejection, two satellites visible. This is an old pic from 1.0.something, but I didn't change much. In other news, you'll get to see a crewed circumlunar mission soon, along with a couple of more modern vehicles=)
  12. The second Earth Orbiting Laboratory (EOL-2) "H.S. Leavitt" snugly wrapped in its fairing prior to launch from Florida... ...and, a few days later, accepting its first two-person crew for a month's stay.
  13. I'm fairly certain the issue is due to the way part costs are applied: in the RP-0 tech tree, there's no issue (except for the ridiculously expensive Castor 120), but those prices are for the case + propellant. In the game, when you place a part, you pay the RP-0 cost for the empty part plus the propellant cost, and HPTB & co. aren't exactly cheap (I just checked the UA-1204: from 4600 to 7500-something funds).
  14. Ooh, a thread I can contribute to @winged, I'm going to copy your posting style if you don't mind. The rockets are great btw! Here's a link to a Dropbox folder with the couple of crafts I feel are good enough to share. I only have pictures for a couple of them right now though, so I'll "present" the rest later. Rhea A+ So, this one is a workhorse. 3.35m wide core with 4 LR89-NA-5 engines on stage 1 and a matching fixed LR-105 with 4 LR-101 verniers for attitude control on stage 2. 3m wide payload fairing when flying cargo. Hot-staging. Payload: roughly 4 000 kg to LEO -or- advanced Gemini for station mission, as pictured below. GLOW: 222.8 t Cost: varies, but 60 million in 2017 $ for cargo version. Rhea B A 1.8m diameter restartable upper stage with an AJ10-118E engine on top of the Rhea A+ stack for GTO and lunar/interplanetary missions. It does look a bit weird though, and the fairing space is very limited. Payload: ~1 000 kg to GTO or ~600 kg to TLI GLOW: ~225 t Cost: 65.4 million in 2017 $ Here's the upper stage in action Iapetos 1A10/1A00 4.57m core diameter, 4m fairing, 2 UA-1204 solid motors serve as its first stage. The two LR87-H2 vacuum engines ignite about 15 seconds before burnout. Version 1A00 has no upper stage and can place...well, I never tested, but I'd guess 7 or 8 tons in LEO. 1A10 has a hypergolic upper stage with 2 XLR-81 engines as used on Agena B. The thingy could be built around 1965. Probably. It also has some issues with low core TWR, but not that bad. The version on Dropbox has a long fairing for station lifting, I used a shorter one for lunar probes. Payload (1A10): ~10 000 kg (LEO), ~3 000 kg (GTO), ~2 600 kg (TLI) GLOW: varies, 526 to 536 t (1A10) Cost: varies, 248 million in 2017 $ for 1A10. These solid boosters are suspiciously expensive. Upper stage in action G-8 "Grom" So, this one launches from Yasny in Russia. 8 NK-9 engines propel the first stage and are arranged in a flared base around the 3.6m diameter tank to avoid sticking out at the edges. Stage 2 uses a NK-9V engine along with a LR-101 for roll control and, like the Rhea rockets, uses hot separation. The fairing is 3m in diameter and can contain a 11D33-powered third stage for GTO missions and beyond. Payload: ~5 500 kg to LEO (2-stage), >1 000 kg to TLI (3-stage) GLOW: ~211 t Cost (2-stage/3-stage): 58/65 million in 2017 USD Test of 3-stage version with engineering payload:
  15. >looks at roundel I'm sure RYAF wouldn't have minded to have a couple of these before the war
