I am never going back to Moho.

[quote name='JedTech']Is overheating really a problem one needs to worry about on Moho in 1.0.5?[/QUOTE]

Just stick a bunch of radiators on and you shouldn't have a problem. Your return heatshield may get nibbled away over time though, which is what happened to me.

Hint:

forget about the transfer window planner. With inclination changes and everything, nailing the transfer is quite hard while most transfer windows aren't really worthwhile.

The easier way to do it:
a) look at the map sideways, depart from Kerbin when Kerbin is at it's AN/DN with Moho.
b) do a transfer burn so that you will just touch Moho's trajectory
c) once you get to that point, do a retro burn so that you meet Moho in this place on your next orbit

It's not the most dV-effcient method, but it's not especially wasteful either. About 4500m/s from LKO, IIRC. The upside is that this approch is quite plan-able, with "transfer windows" come up twice a year (at every AN/DN), and no nasty surprises at your capture burn.

FWIW, my plan is to try to set it up so that I encounter Eve at the node and can then do the plane change via gravity assist.[/SIZE][/FONT][/FONT][/COLOR]

[quote name='smjjames']Retract those gigantors and they'll be fine. Moho doesn't have an atmosphere to aerobrake [I]with[/I] anyway.[/QUOTE]

Not in my experience - even retracted Gigantors exploded in a 45km Kerbin periapsis braking back from Duna. I was very unhappy, as that ship didn't have alternative power...

I did a Moho trip WAAYYY back in the day, in 0.23. Don't remember it to be that hard, and my ship looks kinda tiny compared to what you folks have built :/

And that with a single Nuke. What a pain in the ass the burns were...
Was I cheating? I truly don't know anymore. Though I'd have to add that there was no overheating of the Nukes if you attached them to the right parts. And for the return, Kerbins atmosphere was soft and soupy and cool, so you just dipped as low as you had to to stop the craft.

Moho isn't too bad, because you can use [URL="http://jltsiren.kapsi.fi/ksp/1.0/moho_mission_2.jpeg"]Eve gravity assists[/URL] [URL="http://jltsiren.kapsi.fi/ksp/1.0/moho_mission_7.jpeg"]both ways[/URL]. Another trick is to add an extra 1000 m/s to the lander and park the mothership in a highly eccentric orbit.

The last time I went there, I started with around 6500 m/s in the transfer stage at LKO:

It was more than enough, even though I made some bad decisions on the way there. I was even able to salvage the transfer stage for future missions with some "careful" aerobraking:

Common denominator - there is always a rescue mission after the first manned lander attempt.

Back in 20 something, Moho was the next planet after Duna that I landed on. I didn't know it was hard. Several missions and a trashed Moho surface later the guys made it home. I've yet to get a ship back from Eve.

Laie Is right.

Scroll down to Macollos' post. The only thing he/she is missing is the retro burn at periapse to set up an encounter on your next orbit.

I'd do Moho tourism trips anytime instead of manned Eve returns. ;.;
I remember having a Krakendriveâ„¢ craft that could start from KSC, land on Moho and return to KSC in one piece without using a drop of fuel. It was pretty darn fast too, iirc. Good times.

I first landed and returned from Moho back in, I think it was, 0.23.5. It seemed pretty easy, but then I used a 12km/s dv tug and nuke-powered lander for practically everything. When I went back in 0.90, I couldn't figure out what I was doing wrong, cuz I kept running out of fuel. I finally noticed that I had to use the "right " transfer window, to arrive at Moho at the right part of its highly eccentric orbit. I just don't remember what part of the orbit that was, Ap or Pe. I probably also managed to leave Kerbin at the An or Dn.

I haven't had a lot of time to play lately, hopefully I can try to go back there before 1.1, unless I sandbox it.

Me, I just packed the whole house, and plan to set up a mining operation there to fuel the way back.

That is the kerballed package. Then there is the logistics flight with the base, plus a lonely Trident making the way there on it's own. That, ridiculously low TWR (~1m/s[sup]2[/sup]), ore for compact fuel storage, and nukes FTW!

Rune. Looong burns.

I'm actually working on a Moho mission at the moment! I think if you build right, you don't need to go too crazy in terms of size.

The vessel you see there tips the scale at 50t and puts out a healthy 12k of DeltaV including the lander. T/W on the Nuke stage isn't too painfull either! :wink:

Mine was similar, just a few more nukes and tanks in asparagus staging. One FT(?)800 tanks and 6 more around it. Worked perfectly at my first try, and that was without correct transfer or mechjeb/KER. Not sure what's so hard about Moho^^'

[quote name='DMSP']So, I just finished sending out all the parts for my Moho mission.

And it sucked. 3,000 m/s Ejection burns.

Yeah I haven't been there and I already hate it.[/QUOTE]

I love Moho :). It's not a place many folks go because they're scared that it will take like 3000m/s to get there, then 5000m/s to capture. But it's all in how you do it. My favorite way is to bounce off Eve en route to and from. It makes the trip take much longer, and the timing depends on Eve windows which are the least common in the game, but it's way cheaper in fuel.

But if you go there and take solar observations, it's really interesting. Moho's day is nearly as long as its year, so its inclination makes the sun zig-zag across the sky if you sit there long enough to watch it. But despite all the sunshine, it's still usually pretty dark there. And of course it's hot, too, these days.

You could try a hopper vehicle and refuel part way at like Gilly or something then head to moho and return. It might take alot of the delta V out of it. Working on a trip like that too it as we speak actually. Hitting Minmus to refuel, then gilly, then moho to see if I can make it.

I'm also heat testing my ship with the new stuff in 1.0.5. I just reduced the engines to closer to the needed and saved some weight. I don't think I have to worry about it blowing up from extended burns. Hopefully I am right!

I've never done a Kerballed mission to Moho, but I recently successfully sent an orbiting probe with a lander there. On the first attempt I didn't have enough dV to insert the probe into Moho orbit, but I found out the trick was to time the Moho intercept when Moho is near its Aphelion. That way, the dV requirement is much lower. Also, I launched directly from Kerbin with enough inclination that I didn't need much correction later.
I agree that it's not easy to get there, but with some fiddling it is at least possible. I still don't have the experience to attempt a return mission, though.

[quote name='GeneCash']What? you can't go to Moho with only 7,217 m/s delta-v using 2 Eve flybys and 8 Moho flybys over 10 years like this guy?
[url]http://forum.kerbalspaceprogram.com/threads/74375-Lowest-Delta-v-to-Moho/page3[/url][/QUOTE]

I've a simple return vehicle. It's not optimized, because I want him to go to Moho nearly anytime. I've packed it with 6650m/s from LKO to LMO (quite a huge margin, i think). Ageter refueling, the return trip is 5300m/s (with a pre slowdown befor entering Kerbon atmosphere.)

I like Moho. I've gone there several times before... despite never even once going to Dres, Jool, or Eeloo. I don't know why... I must be some kind of moth, drawn towards the flame of the sun... :D

Even when I played with Realism Overhaul a long time ago, I went for a Mercury mission, direct ascent. It resulted in [URL="https://dl.dropboxusercontent.com/u/44754370/screenshot18.png"]the largest rocket I have ever built[/URL]. ([URL="https://dl.dropboxusercontent.com/u/44754370/screenshot19.png"]Payload for scale[/URL] - one unmanned lander and one tiny SCANsat to remain in orbit)

Such an absurd contraption... today I would build it very differently. But I still went anyway, and it worked, too! :)
