Mr. Sandman

Thanks a lot for the precious infos , I'll surely give a look at the math and try the mod.

I've built a big ship for a manned travel to Mars.It's powered by 3 nuclear engines with Liquid Hydrogen as fuel.The complessive burn time is around 2 hours and the fuel is just enough to the whole trip to Mars and return ( no errors or DeltaV waste possible).So , what's the best way to save as much DeltaV as possible in maneuvers by doing them efficently?Are there any rules that I have to know on how to save fuel? The ship plays a lot on throwing away empty tanks ( life support and fuel), squeezing DeltaV to make the vehicle lighter.Start mass : 600 tons. End mass (from Mars to Earth): 150-200 tons.

The Mars plan is progressing pretty good.I'm exercising myself on docking the large parts of the Copernicus ship.I'll have to wait to start the mission because my PC has difficulties handling the MAV and MDV(high part count , around 170) Meanwhile..

Preparing myself for the greatest mission I ever done. [Sorry for the big picture spam] This is the Ares V with the MAV as payload.It weights 6000 tons (twice a Saturn V) and can transport 200 tons in LEO.It has a thrust of 84,943.4 kN at sea level.

Hello , would it be possible if KVV had a camera rotation with degrees?I mean , it would be nice if there was a window to select the exact degree you want (Like 90 degrees), so you don't have to try to find the perfect angle to take the screenshot.This is just a request , obviously.

Got it to fly!The problem was pretty simple : as you said , the nosecone was way too light and the CoM was way too down the vehicle.I just measured the exact half of the vehicle (fairings included) and put the CoM a little bit down from there.This gives stability and the torque to keep it inclined 30-40 degrees.

Yeah that should help.After all I'm traveling in thin air at 3400 m/s.

Sadly in RSS/RO Mars has a realistic atmosphere (600 pascals, so pretty much thin) and SAS wheels are useless if only not for small probes (again, realistic).I will try to distribute better theweight and see what happens.I solved the thrust problem, but the damn thing flips again.

Ok so I'm trying to bring the Thrust down and I noticed that the Thurst problem is the fairing itself (I moved the entire fairing up and down , the thrust moved with it)

Booting up KSP now , I'll try make the nose heavier and see what I can do with the lift on the back.I say that the thrust doesn't come from the engines because when the fairing is gone , they point straight down , making the thrust vector perfectly alligned with the CoM and CoL.

I'm having troubles with FAR and as a guy suggested me, I'll post the link here (because I don't want to fill an entire page).Disclaimer: It's probably just my fault and FAR is just fine.Thanks for the solutions. Edit: Managed to get the CoT down by lowering the thurst in the Solid motors for parts jettison.Going to test it now.

Yeah I'll repost this there too, thanks for the tip You can't reduce thrust in RSS/RO and the engines are not the thrust there (I think that's the aerodynamic thrust)

Hello , I'm trying to land very heavy payloads on Mars and for this I'm using a gliding technique (Pretty much like the Space Shuttle). My first payload , the Mars Ascent Vehicle (201 tons) lands safely on Mars with Gliding+Parachute+Retro rockets As you can see the CoT is below the CoM, which is below the CoL and I can tilt it at 40 degrees without problems (so it's pretty stable). But for some reason.. This is the MDV.It flips in the air if it's more than 25 degrees inclined(I need around 30-40 to slow down) In the Mars Descent Vehicle the CoT is above the CoM and CoL.I have no idea why this happens and how to fix it.Is this why it flips?Thanks for the answers.

So yeah , I did it!Today I tested a new way to sky glide on Mars and it worked flawlessy! That is a 70 tons payload slowing down in the thin martian atmosphere. The payload is the MAV (Mars Ascent Vehicle, in the picture above) and the MDV (Mars Descent vehicle , to land and use as home for the 200 days stay)

Photo of the Ares I rocket on the launchpad at sunset. My Mars landing plans are almost done, but I ran into some problems: I've to land two 70 tons payload on Mars and the only way to do so is by sky gliding in the Martian atmosphere. Yes, skygliding a 70 tons vehicle in a 100x (~600 Pascals , vs our 1.013 x 10^5 Pascals) thinner atmosphere. Any suggestions?

I would like to make kerbals come out from docking ports, but I have no idea on how to force them to do so or if is it even possible.I appreciate alternative ways if this is not possible.Thanks for you support.

I have no idea why buy my IVA/EVA is not working.I can't send a Kerbal on EVA because the windown on the bottom right is gone and even by pressing C nothing happens. As you can see there are 5 Kerbals on board but the windows on the bottom right are gone and C doesn't work. Mod list: Thanks for the help! Edit:Only the Orion Orbital Module has this problem.I have no idea why, since the capsule has an hatch.

I'm trying to do a Voyager-ish probe , so I would avoid big retractable radiators.I saw a mod called "Heat Pumps" (http://forum.kerbalspaceprogram.com/index.php?/topic/115734-heat-pumps-v130-for-real-fuels-may-1-2017/) and I'll try it later.I just want to drain my heat from the Plutonium RTG in a sneaky way.

They are hidden inside the probe and they are fixed radiators.Does a fixed radiator differ from a retractable one?You can just explain me the way KSP handles heat and/or general rules to prevent this.

I'm buidling a deep space probe to Saturn and Jupiter, but the core overheats (on Earth and space) after a few minutes in flight.I'm using an RTG to power it and some radiators to cool it down,but they don't seem to be powerful enough or even to work.I noticed that I produce way too much electricty than I actually need and maybe this is the cause of the overheat. This is the message I get and a picture of the probe for comparsion: So yeah , any solutions?Maybe less power?I really have no idea.

Testing different parts of the Copernicus spaceship in LEO.The first part with the BNT engines (Bimodal Nuclear Thermal) weights around 75 tons.The entire Copernicus spaceship is 466 tons. Final ship assembly plan :

Ares I rocket from the Constellation program, in development for a manned Mars landing using the Copernicus , ascent and descent modules. (RSS/RO)

There was something to fix on the Real Fuels stuff and sadly some files were missing , now it should be okay.

Yeah the RO way looks better and up to date , but I would leave a message on the CE thread (maybe asking a moderator to let someone do so) saying that the 1.2.2/1.3 fixed version is now supported on the main thread of RO.

That was fast!Thanks a lot for fixing those old (but unique) parts.Is Constellation Essentials going to be updated (on the CE thread) or is it going on the main thread of RO?
