Phew, lucky me :)

Yep, that's the magic of screenshots :D I'm recording my flights so I don't have to bother about making screenshots while maneuvering a shuttle, so if you are curious how the flight really looks, I'll upload it for you ;) 

Let's have it then! I wanna see you struggle! ;)

Well, I have 13GB of struggeling and 2GB with the successfull mission...and I'm pretty sure I already delete some of the struggeling parts^^
Anyway, I have to mute the video so youtube doesn't claim a copyright on the music I'm listening to. I'll PM you as soon as it is muted and uploaded ;)

Just dunk it in here, I'm sure others want to learn how you did it as well

Too many good videos out there, I'm shy :P

But if someone really wants to see it....
I'm not a profi video editor...not even an amateur...and the video is not recorded to be shown to others, so no fancy camera tools :P 
Sound is muted in both videos, you have to listen to your own^^

Here is the actual mission (after watching it again...it's not too bad at all):


And you guys want something to laugh, so here are some of my fails :D Unfortunately, some of my best crashes are already delete, sry...

If someone will notice: Yes, during the last two crashes I had 'infinite fuel' enabled because I wanted to save the crew and was no longer able to revert the flight...

@4x4cheesecake

Your final looks great! It's also nice to see it wasn't easy to get it in that smooth

The most noticeable thing is the lack of pitch authority, which is why I added the canard to my own design. Makes it much more pleasing to fly!

Thanks :)

For me, it was the hardest challenge so far and took me a lot of time to do this (I already tried it when I started these challenges months ago...).

And yes...the canards saved the mission for me as well. Initially, I just increased the pitch authority on the elevons but the results were pretty bad. Putting some canards in the front instead results in a orbiter which is actually enjoyable to fly :D
On the other hand...look at my very first crash in the 'fail' video: the approach actually looks really good and I was surprised when everything exploded. So I spent most of the time trying to land the orbiter with its bulky behaviour, thinking that I'm just a bad pilot, instead of improving the orbiter. Basically, the biggest issue was me beeing stubborn :D

Increasing the authority just turns it into an airbrake causing it to stall.

I am amazed there's actualy multiple people that managed to successfully fly the real thing! It basically handles like a brick. And the speeds they landed the thing at, not a feable feat!

It helped me during the 'catch an astroid' mission but in this case: yes, just an airbreak^^

Do you know this video? It's just crazy :confused:

Artemis I Shuttle Launch and Landing for STS-1

Highlights:

mmXDr7s.jpgH92Hcf2.jpg

LD9fnY4.pngvg4euON.jpgYDLRA9L.jpg

This was really hard to do, especially the re-entry. Half of the Elevons and the Taillfin overheats every time, but this is not detremental for the Artemis Ishuttle. 
Other difficulty was Liftoff, but if Mechjeb is allowed (Except on asccent, but doesn't matter because i didn't use it) than TCA would be allowed, which is doing the same as MC; mmaking your life easier.
It simply controlls the power of your engines so you don't flip. The ascent is all manual as always.
Also the Shuttle is a little differant than the classic Buran-Style ships because why not. It is relatively stable in reentry.

Very cool design, with a proper ramp !

But is your orbiter a SSTO ? If I remember correctly you have to stage the lifter !

9.  SSTO's are not eligable for entry to the challenge

Also why did you choose to use whiplashes (heavy !) and mk3 control surface (heat resistance) ?

1) It is not an ssto, as it separates multiple times. There is no limit how far your Launch System can go, and this was confirmed by don.

mk3 Elevons? I do not know where you got that idea because i used fatwings. Although next-gen shuttles for next mission do have mk3 elevons in tthem
I choose whiplashes because they (in the stats) gave the most thrust. can switch them though.
The rammp will be used to deliver space stations and orbital outposts :D

@Artienia That's a really cool shuttle with an unsual design, I like it :) Haven't seen many front-loaded vehicles yet.

The fatwings are the mk3 elevons ;)

I don't see any problems here...the lifter got staged and I'm pretty sure that the rule applies to horizontal launching SSTOs. Otherwise I might have to return my Mun badge, because my new orbiter CAN actually reach orbit on its own (without any payload) xD

Oh i didn't know that. Well i regretted using that anyways because it was heavy, gave very little lift and always exploded during reentry

Yeah, they are made to be used wihting the atmosphere, not to leave it. Try the Big-S-Elevons instead, they are way more heat resistant :)

How does your descent trajectory look like? If you apporach the KSC in a steep angle, you will always have parts that will explode by overheating, i.e. RCS thruster.

You know crater lake? I break there...

I know the lake, it is the same location I start breaking as well :D

You probably just need find a good pitch angle for your orbiter. I remember the heat problem from my first SSTOs and Shuttles but the heat became less a problem with every flight (without any major changes on my crafts).

I hope we'll see more flights of your Shuttle :)

Making the Payload missions now. I already did it but reentry was always very weird and mmy plane always got flipped

Nice landing

I would look at how nose heavy you’re ship is

you were using a lot of rcs to keep it flying and it might be a problem later on

but still, Nice work

Thanks :)

Actually, I don't need the RCS thruster to fly the orbiter through the atmosphere but I had too much fuel left. The shuttle is designed to deliver a 50t payload to the surface of the Mun but I used it this time for a delivery to LKO without taking out any fuel so the orbiter was stll pretty heavy and the RCS thruster helped to minimize the turn radius ;)

michal.don needs something to do when he return from his holidays, so lets continue doing challenges :D

Here's my entry for:

STS-3T: Cassini-Huygens

N1iqRLi.png


I managed to visit every Jool moon and still had plenty of fuel left in the probe. For design purposes, I've added 'DMagic Orbital Science' to my mods and put some science stuff on the probe (i.e. Magnetometer). Maybe, you'll notice an empty 'Ore' bar in my ressource window, that's because I've added a small empty ore tank to the Huygens lander to increase the buoyancy :D
The whole imgur album contains 54 pictures, I'll just post the highlights here ;)

What an awesome space bus it is! It really resembles you landing a proper american school bus :D

Artemis I-b and Artemis II-b Shuttle Launch

Highlights I-b:
E00JQJ7.pngQMNDP3k.pngCxDpY6I.png

Highlights II-b:
6ed4jFK.pngyDbXAhb.pngzm402kk.jpg

Here it is as i promised, Artemis I-b and II-b Missions with a 41 ton custom-fit pod.

This mission took me a lot longer than the previous (obv), around 2 days of irritation (mainly during reentry, this craft was a lot less stable than Artemis I
The easiest part of the mission was docking; to my suprise. Randevou was pretty easy too. The mod fit perfectly into the cargo ramp (which i feared wouldn't be case) on the first try. i have done a lot of docking but this was the easiest by far. Returning the Pod (Art II-b) was kind of hard as the plane was 40t heavier, and had a bad time flying
