Pretty much no engine would work on the surface of Venus, as the atmospheric pressure pushes so hard back against your exhaust. The same effect lowers the efficiency of a rocket engine at the surface of the earth, but that effect is so intense on Venus that rocket propulsion from the surface wouldn't be worth it. Someone could make a mod for using balloons to float a craft up from the surface of Venus, an existing mod might even be modifiable to do that already, but I haven't looked into it. Exploiting buoyancy would be the way to go. Link to comment Share on other sites More sharing options...

Maybe something like RD-180 or RD-191 should work somehow on Venus in theory. There is atomic jet engine from atomic age, it should work, but I want Venus rocket...

GiantTank Posted March 20, 2016 Share Posted March 20, 2016 What is the biggest RO engine available? I know of the 5x F1 cluster, but is there anything bigger that has a working config? (Not SRBS) Link to comment Share on other sites More sharing options...
NathanKell Posted March 20, 2016 Share Posted March 20, 2016 @Alexoff even apart from the pressure (which will reduce even massive-high-chamber-pressure engines' Isps down to very little), you need to build an engine that can _itself_ survive the temperature and pressure. Combustion chambers aren't rated for having combustion-chamber-level heat and pressure on the outside. Link to comment Share on other sites More sharing options...

(Not SRBS) Take a look at the M1 for the Apollo Nova program (that sadly never was): "Aerojet's M-1 was the largest and most powerful liquid hydrogen-fueled liquid fuel rocket engine to be designed and component tested. The M-1 offered a baseline thrust of 6.67 million N (1.5 million lbf) and 8 million N (1.8 million lbf) as its immediate growth target. If built, the M-1 would be larger and more efficient than the famed F-1 that powered the first stage of the Saturn V rocket to the moon." https://en.wikipedia.org/wiki/M-1_(rocket_engine) Link to comment Share on other sites More sharing options...
Phoenix1583 Posted March 21, 2016 Share Posted March 21, 2016 I've tried loading the game a few times now, always getting stuck here: The game hasn't frozen given that the little text stuff keeps switching but it won't load past this point.

coldblade2000 Posted March 22, 2016 Share Posted March 22, 2016 hey, I'm going to start my first station, and I wanter to ask beforehand. What are the rules for docking ports to connect? in my game there are two APAS-89/95 docking ports. One resembles the normal docking port, and there is an "Apollo docking port" that uses the same model and texture. They also have a bumper that can be deployed. Then there is another APAS-89/95 that looks more like the the passive APAS variant. Here is a picture comparing both: I was wondering this: Would the two be able to dock together? Which should I put on my station and which on the capsules? If I want to add modules to the station, which port should I use? Link to comment Share on other sites More sharing options...
NathanKell Posted March 22, 2016 Share Posted March 22, 2016 @coldblade2000 yep, should work: APAS will work with APAS. Apollo won't work with APAS, you'd need a docking adapter. Link to comment Share on other sites More sharing options...
Wardstone111 Posted March 22, 2016 Share Posted March 22, 2016 Just a suggestion for another mod to add onto your list: British Rockets. It has compatibility with RO but just a suggestion. Link to comment Share on other sites More sharing options...
cytosine Posted March 23, 2016 Share Posted March 23, 2016 Question about the Lander Can: I'm trying to create 'my own Apollo-like' lander or something relatively close and way more ugly... But proportionally the Mk2 Lander Can seems to be overweight and under-capacity compared to the LEM Ascent Module. The Mk2 only has 1000L tank volume compared to 2680L on the LM while the LM is only slightly larger when placed side-by-side. Adding a procedural tank evens the size and gives it the necessary tank volume for fuel, but when full the Mk2 weighs 6 tons when able to produce the equivalent 2500dV as the FASA LM with 4x RCS thrusters and enough supplies for 2x days. And with all of this the LM only weighs 4.6 tons. When I add food and water to the Mk2 it topples around 7 tons, yikes! The only real difference I noticed is that the Mk2 Lander Can has 8m/s crash tolerance, is there anything else that would explain the 3 extra tons of weight? I promise I haven't loaded any moon rocks yet! Link to comment Share on other sites More sharing options...

rsparkyc Posted March 26, 2016 Share Posted March 26, 2016 (edited) Anyone have any ideas as to why I can't complete these two missions? I feel like I've done everything right. All the details are in the screenshots. EDIT: one thing I noticed was that my mission timer reset when I jettisoned my last engine. I think that I may have flipped my root nodes around, maybe that's why the missions aren't working? Edited March 26, 2016 by rsparkyc Link to comment Share on other sites More sharing options...
NathanKell Posted March 26, 2016 Share Posted March 26, 2016 @rsparkyc the timers on EVA and first orbit are different; did you stay in orbit (before EVAing) long enough for the spacewalk orbit-first timer to complete? Link to comment Share on other sites More sharing options...

Would EVAing reset my timer, causing "Human Orbital (1/LEO)" to fail? Link to comment Share on other sites More sharing options...
axelaxel Posted March 26, 2016 Share Posted March 26, 2016 Hi! I I Seemto not be getting any lunar rated heatshields, only for LEO, which makes my lunar returns a bit more exciting than I would want. They are not in any research nodes either. Any ideas? I am running a standard CKAN installation with RO/RSS. Thanks! Link to comment Share on other sites More sharing options...

You could land a spaceplane and use a firespitter electric prop to get you out of the soup then have the centre become a normal rocket. Link to comment Share on other sites More sharing options...
NathanKell Posted March 26, 2016 Share Posted March 26, 2016 @rsparkyc I don't think it would; I think it's more likely the weird staging you mentioned earlier. I have done similar missions (get both contracts, stay in orbit for ~5 hours to complete both, then EVA and store data, transmit the data once back inside, then land) and not had problems. @axelaxel that does sound like a bad install. Try installing only the mods that CKAN recommends (i.e. already has checked -- don't check any others) when you install RP-0. Link to comment Share on other sites More sharing options...
rsparkyc Posted March 28, 2016 Share Posted March 28, 2016 @NathanKellLooks like the staging issue was the culprit. Thanks! Link to comment Share on other sites More sharing options...

rsparkyc Posted March 29, 2016 Share Posted March 29, 2016 One thing I've noticed that that if I have a 1kN engine hooked up to a hydrazine tank, and then disable the tank (to prevent RCS from firing), if I try to run my 1kN engine after reenabling the tank, it stays in a flame-out state. I've tried cycling the engine state to no avail. Is this intentional? Link to comment Share on other sites More sharing options...
