Any tips? (aside from Mechjeb)
Alrighty, so I just tried a docking now.

Two ships, Castor and Pollux. Original, I know.

Took some doing, even with new MechJeb. I've managed it without before, but for some reason the rockets were all over the place this time.

Not a very exciting rocket, but it did the job well.

Image

Always explosions whilst jettisoning spent stages. No damage to the main engine or stack, just the debris exploding on the way.

The real trick seems to be to make sure each craft has targeted the other one. I made sure in particular to target the docking ports. And then to drift very very slowly together. Once they were about 40-50 metres apart, I dropped down to 0.1 m/s. The trick whenever you're doing anything where you need to be close to something else, especially docking, is to do it bloody slowly.

Eventually if you're close enough and have been facing in the correct direction, they'll snap together fairly abruptly. To be honest, I preferred the plugin way of doing it before they'd incorporated docking, but oh well.

The bloody slowly bit is what gets me, last time at about 30m away, they were travelling really slowly and it turns out you have to wait for it. I just don't have the patience for it.

Patience is 100% essential. You just null out your velocity relative to the other craft and drift together.

Was going to try to dock, but i got distracted by the new mod i got that allows me to eject my kerbals out of the ship and another mod that gives them parachutes.

Just uploading some bits and bobs. Imageshack instead of imgur because apparently imgur is being bitchy over some of the images.

First, apparently for some reason Castor and Pollux became undocked, so I've returned them to Kerbin. Castor took a more leisurely, safe re-entry angle, but to see some real re-entry effects I took Pollux on a more severe angle, which was fun to watch, particularly the solar panels shattering, which apparently I didn't get a screenshot of >_>

Image

Image

Image

Image

They both landed safely, but there are too many pictures as is.


Other stuff, Chollima II satellite launches to the Mun to map the surface. Originally it went in around the equator (shown in the picture but a much closer orbit), but I angled the orbit later to about 45 degrees. It's mapped most of the surface, but I still need to cover the poles. I'll be swinging it around and sending a lander to some interesting spots on the surface in the meantime.

So I figured I would give KSP another shot. A münshot, to be precise.

After getting back into the game during some particularly boring studying for a Macroeconomics final, this morning I decided it was high time to go to the Mün.

I built the following rocket.

Image
You can tell it's safe when the RCS is firing that much before lift-off.

It's a three stager. First stage is surface to orbit, and elongates the orbit to an apoapsis of about 11.4 thousand kilometres. Once it's in the Mün's gravity, the second stage kicks in to establish a stable orbit. I went for a circular orbit of around 75 kilometres. Ended up running low on fuel, so it was quite eccentric (pericynthion of about 63 kilometres, apocynthion 88 kilometres) but it was close enough.

Now, when I got to the near side of the Mün, I killed the sideways motion and started the descent. Ran out of fuel, so I had to bring on the third stage early. Now, stage three really wasn't meant for this. It's only got three side thrusters and three RCS thrusters for basic controls. I also failed to include an SAS module in this stage.

I would live to regret that decision.

The ~50 kilometre descent was thus done with less fuel than optimal and absolutely no computer control, since the RCS tanks went dry during the first stage (Poor fuel management? Yep). My own handling was spotty at best with the light craft I was getting worried that the planned return trip wouldn't be feasible. And then I realized I was burning through about twice as much fuel as I had expected to, and suddenly the return trip seemed like the least of my worries.

Indeed, the tanks ran dry while the craft was about 200 metres above the surface, and it started accelerating from a modest 6 m/s up to about 23 m/s before smashing into the surface. Fortunately, the landing struts bore the brunt of the impact.

Image
It's a landing all right, but I hesitate to use the word "successful".

And so, with no fuel, no RCS, and no backup option, I was forced to redefine the mission parameters somewhat.

Image
In the aerospace industry, this is referred to as "pulling a NASA"

I'll do my best to keep you all up to date on how the probably rescue and recovery mission goes. ;)

So first of all, I sent up some mapping satellites. This is what they've collected so far. Unfortunately for some reason the mod doesn't map whilst the satellite is on rails (not selected/being flown), so I just spin them up to 50x speed and do something else for a while.

Kerbin

Image

Mün

Image


On the Mün I've sent the satellite to map the poles whilst in the meantime I land at an interesting anomaly on the surface. The lander, named Asparukh I (name from BgKnight), was launched on the same lifter as Chollima II, unimaginatively named MLV-1 (Münar Launch Vehicle 1).

Image

Most of the flight went fine (except for a handful of inexplicable crashes), and as we descend towards the surface, we can see a glimpse of what we're flying towards.

Image

After landing short by a few hundred metres and hopping about a little on my tiny engines (thankfully I had plenty of fuel for that), I manage to come to a stop near my target and set up my Münar lander/research station, equipped with temperature and gravioli-measuring equipment, all of which is stupidly on the other side of the lander in this picture >_>

Image

In case CWest or zenburg or anyone else wants to find what I was looking for for themselves, here's approximately where it is:

Image

If you don't mind or you're just lurking, here's what I found:

The Neil Armstrong Memorial! I wasn't quite sure what I was heading for, but I knew of the memorial being a thing before, so I was quite pleased to find it :3

Sent another lander, partially to explore other anomalies, but mostly to test out how MechJeb's landing computer handles things.

Interesting view flying over the Mün's surface, you can see where Asparukh I landed, indicated by the grey indicator in the distance.

Image

Had a little trouble with the landing, mostly because I was unaware how close to the surface we were as the Sun hadn't risen so I had no shadow to judge it by. Also MechJeb decided to fly parallel to the ground for some reason. Anywho, lost a solar panel and fell over, but managed to right it and sort everything out.

Image

Here you can see what I was aiming to land near. As you can see from the indicator about where Asparukh II landed, I'm a bit far away, but probably more because my coordinates weren't dead-on. It's another anomaly you might want to find for yourselves, so it's spoiler'd.
SpoilerShow
Mün Arch!

Image
Anywho, future rover missions will attempt a landing either closer to it or at Asparukh II so we can drive to it. It's a little far away, so I'll probably land a bit closer.

Tick off another entry on the bucket list.

Using the same basic launch vehicle as before (More fuel in stage two, less in stage three) I took a shot at landing on Minimus. Apparently that's the next logical step after you've been to the Mün. I also replaced the frickin' RCS on the lander with an ASAS, having finally learned my lesson there (Though for the record, this is the "Minishot II", the first one having fallen victim to my trigger-happy space-bar finger).

From a fairly standard circular orbit around Kerbin, I burned prograde until the apogee was somewhere around the 46 700 kilometre mark. If you're interested in knowing, I started the burn when (Using the NavBall) Minimus was 5 degrees above the horizon. Then I burned 90 degrees from the path of motion (antinormal, to use the proper phrase) to kick the rocket onto the same orbital plane. The manoeuvre feature, which I am now in love with, makes this quite easy really.

Image
Obligatory picture of the transfer orbit.

In a rare though welcome twist I actually found that I had a little bit too much fuel in the second stage. I probably could have saved some hassle and just rolled out with the exact same rocket as I used in the münshot. For reasons that will quickly become obvious that would indeed have been a better idea. Either way, eventually I end up in the sphere of influence. Then I established an orbit. You know how these things go.

Image
You can actually use this rock as a slingshot? I'm pretty sure people have built münar landers bigger than Minimus.

Easily the most difficult part was actually getting from orbit to the planet's surface. Yes, I know it has low gravity. Yes, I know it doesn't have a messy atmosphere.

However, Minimus is also apparently the missing link between golf balls and crumpled up wads of paper. Trying to stick the landing was a massive pain in the ass that required three different attempts at different landing sites.

Image
Would it kill Minimus to be a little bit more even?

On the way down (the third time) I realized the implications of Minimus not being tidally locked, namely the fact that the nice, even surface I was trying to land in was rapidly sliding out from under me. I ended up putting the bird down on a 45 degree incline. The resulting toboggan ride to the bottom was long, arduous, and frankly just a little bit embarrassing.

But hey, we got there eventually! Bob Kerman (Yes, that Bob Kerman) headed out on an EVA.

Image
Not actually trying to smile, just a symptom of early-onset frostbite.

And since apparently this is a thing, here is the "customary shot of lander in the light of the sun (Kerbol)."

Image
"No, seriously, some extra body heat would be great right now."

I was rather excited to have an astronaut on another body with some actual hope of returning home alive, and I wish I could say this whole thing has a happy ending. Sadly, I overshot the escape velocity of the moon (Easily twice as fast as I needed to be going to get off this rock). When I attempted to burn retrograde to fall back to Kerbin, I quickly ran out of fuel. Just ended the mission instead of planning a rescue, so I guess that means I'm 0 for 2. Better luck next time?

After much screaming, panicking and aggravation, I have finally docked! I nearly failed as the first satellite ran out of RCS fuel so I had to move the second one towards it, only for it to nearly run out as well. Ended up docking with just less than 10 units of fuel.

I never intended for this to work, so i didn't bother to take earlier screencaps. To my surprise, it succeeded.

Once more I have landed on the Mün, this time a manned landing. Yet this may have been my most difficult and irritating Mün mission since I figured out how to do it successfully.

We begin with the Ormal I rocket. Named after the second of the Two Lamps created by the Valar when they entered Arda (Tolkien mythology, yay). It's a fair simple rocket, far less complicated than what I would usually use to go to the Mün, but I figured I'd give simplicity a shot and see how it went.

The answer is not well.

Image

The journey to the Mün was fairly routine, as was the landing, although I was conscious that I might be cutting fuel pretty fine since my lander/return stage did the entire injection burn to reach the Mün from Kerbin orbit. But meh, it'd be fine.

We got to the Mün and took the usual vanity shots. Due to concerns that I fudge things up I turned away from landing at my target, but you can see it at the edge of the crater I landed in.

Image

Image

Image
Tiny white dot in the centre of the screen is the lander, Mün arch is visible on the horizon in the centre.


The return is where things got tricky. My projections were that I had sufficient delta-V to escape the Mün's gravity and let Kerbin pull me in. This did not work so well. I escaped the pull of the Mün quickly enough, but my orbit put me in a 13 million metre x 10 million metre orbit of Kerbin. And unfortunately I had insufficient delta-V to kill enough velocity to drop my periapsis into the atmosphere of Kerbin.

Kerbals Frank, Kenbus and Herlin were not best pleased. So they hung around in the capsule for about 50 days, living off their recycled urine and sleeping long hours in an intense state of hibernation Kerbals have evolved. Initially only useful for waiting for the bakery to open and for new rockets/things that explode to be built, it turns out it's quite useful for space travel.

Unfortunately when Kenbus awoke from his urine-filled night terrors, he realised two things. First, that he knew why he'd dreamt he'd been swimming in an Olympic swimming pool of urine, and second, that something was very wrong. Whilst they had slumbered the days away, Ormal I had once again been caught in the Mün's sphere of influence and flung into an even wider orbit. They were well and truly stranded.

Many plans were considered. Burn what fuel we could to reach as close to Kerbin as possible and await a rescue ship that could catch Ormal I whilst it was close to the planet? Go on EVA and try to use the spacesuit RCS thrusters and their limited fuel to nudge the command capsule into the atmosphere once they were close enough to Kerbin? Give up hope and try to collide with the Mün? Dive from space after getting close to Kerbin and plunge to their deaths? It all seemed hopeless.

Yet after some 133 days adrift, Frank has a sudden brainwave. The computers were blinking away, still powered by the Sun. And a new course had been plotted. Somehow, by some miracle, they now had just enough fuel to skim Kerbin's upper atmosphere and use the drag it created to return home. Waiting but one more day, the Kerbals strapped themselves in and praying to the Great Huojin in the sky, they activated the engines.

Image

The burn was a success, and just as the engines flamed out and died, sending the rocket into a spin, the computer recorded that their projected path now intersected Kerbin's atmosphere.

Image

Re-entry was a hairy moment, and fears that they would skip off the upper atmosphere and be plunged back into deep space were compounded when a projection showed that if they did so, they would be caught once more on the wrong side of chance and slingshotted by the Mün to some unknown place.

Thankfully, they ship began to catch the atmosphere more substantially, and on a wing and a prayer, they returned safely to Kerbin.

Image
I promise it touched down safely, I just thought it'd look cooler with the parachute showing.


Next up, Minmus again, and then finally I can recreate my two-part Duna mission rocket that never quite got to travel to Duna.

In lieu of any pretty pictures from Minmus due to the fact KSP keeps crashing on me and I'm waiting on someone to help out in the Support forum, I've been planning my Duna mission (a two-parter with separately launched CM/Orbiter and Lander which dock in Kerbin orbit and head to Duna), and taking a trundle around KSC in a shitty rover.
Some interesting things to be seen.Show

So, are you guys experimenting with planes at the moment? My fastest record is Mach 3 after 2 days of building several feasible planes.

Actually I was dicking about with planes recently. I haven't really explored thinner parts of the atmosphere, but I can reach about Mach 1. The best thing to do is to fly about in the mountains west of KSC, low enough to see your shadow. That's pretty cool. Most of my heavier planes are fairly unstable though. I get a lot of planes that like to pitch wildly up and down.

http://forum.kerbalspaceprogram.com/sho ... lope-Dodec

So I'm tempted to install this mod so I can use airships to have an easy lift-off from Eve and make bases in Jool's atmosphere. Shit could be awesome.

In the meantime, lets talk about my Minmus mission I did a little while ago! I launched Ormal II, which was basically just an Ormal I rocket with a modified lander to cope with lower gravity on Minmus. The flight over and such was repeatedly disrupted by the game crashing, so I had to launch like four times before I finally managed to get to Minmus with my engines off so the game could quicksave before crashing. Hence no pictures. We do, however, get this orbital map view of my descent onto the frozen seas of Minmus!

Image

It's worth noting that for some reason, the crew of Ormal I which was stranded in Kerbin orbit after visit the Mun decided they wanted to be on this mission too. It was probably not a particularly good idea.

We had plenty of fuel, so everything was going well, but the lander stage was RCS-powered, so it was further up, had less power, and even if I wanted to I couldn't land on Minmus with the descent stage because it had no lander legs. As we descended, we made the final burn and began to descend vertically. As we approached the ground, we jettisoned the descent stage and activated RCS thrusters on the lander. Unfortunately three things happened. First, the descent stage hit Minmus, exploded and showered the lander with debris. This debris then knocked the lander around and off course slightly. We also had to correct because the debris was also all over the ground below us. And finally the lander may have lost some thrusters, or was just moving too quickly, so hit impacted hard.

Image

Yeah. The lander legs fell apart pretty fricking quickly, following quickly by the fuel tank exploding and everything else just shattering or tearing apart. I cringed and held on for the command capsule to hit the ground after it had bounced up, waiting for the impending explosion. Yet thankfully, it's made of sturdier stuff, and before long came to an unstable rest on a body with stupidly low gravity.

The KSC exploded in shouting and announcements, and Jeb, Bill and Bob were roused from their beds. It was time for Prime Crew to come into play. A rescue mission, with additional capacity to bring the stranded kerbalnauts home safely. Ormal III was ready. The flight was fairly standard, once more, until we reached Minmus. Landing precisely near Ormal II's capsule was proving difficult. Mostly because yet again, I had dropped my descent stage directly where I wanted to land. But this time, it didn't explode. Much.

Instead we had some fuel tanks, brimming with lovely explosive liquid, right where I wanted to land. And as I came into land, my lander legs got caught on the tank and the whole thing nearly fell over. Aborting the landing, we had to ascend slightly again and try to land a little further away. Although apparently "a little" to Jeb means "over a kilometre".

Image

So the Ormal II crew had to EVA a long way to reach the rescue ship. Rather than walk at a ponderously low speed across Minmus, we instead elected to get there using RCS thrusters to fly. Bear in mind when I say "fly" that when you jump on Minmus, it is very easy to get worried you'll reach escape velocity on your own.

Also apologies for dark pictures, we didn't have time to wait to rescue the crew, so they were on the dark sided of Minmus by the time we got there.

Image

Image

There were some issues with flying very quickly for over a kilometre on RCS thrusters on the EVA suits. Such as being unable to judge your speed. Every time, I managed to overshoot the rescue ship because I was flying too quickly, sending the Kerbals tumbling for anywhere between 100 metres to a kilometre past the ship and needing to send them back. They got pretty knocked about >_>

Image

Finally we managed to load them all up. Sunrise wasn't too far away by then (... with time warp), so I took a few snaps in the light before heading home. I also waited so we could fly towards Kerbin, instead of away from it.

Image

Image

The return was fairly routine. We kept the engines on for re-entry, because I knew the habitation module would make the craft too heavy to risk parachutes alone, so I wanted to use the spare fuel to slow our descent on parachutes.

Image

There were some extra parachutes attached too, just to be safe. Turned out we kinda needed them, since when the chutes opened we lost one of the engines+fuel tanks when it was torn from the lander, and when we touched down the other two engines exploded too. But apart from that, a successful rescue mission! Safely home :3
