    [Scenario] Rendezvous With Roche

    Prologue

    It was a cool mid-Blaugust day at the Kerbal Space Center.

    Administrator Joseph Kerman IX sat in his comfortable swivel chair, elbows on his desk and his small hands on his chin - quite obviously bored out of his mind. The chief engineer Billy-Bobthompdorp Kerman suddenly burst into the room! Joseph started, and his elbows slipped off the desk, sending him hurtling face-first into it - knocking him out cold. Billy stood there for a moment, unsure of what to do. He was about ready to simply sprint away and pretend he didn't see anything when Joseph came to. Billy spoke carefully,

    "Ah... you're ali-- awake."

    "Yes... now what did you come barging in here for, anyway?"

    "The first expedition to... R-roche has failed They ran straight into it and are now stranded."

    "Ruh-roche? What's that? Also, who are you, and where am I?"


    Billy sighed and shook his head, his initial fear of having accidentally killed the administrator now overcome with annoyance. "Okay, I'll give you the short version. You're the administrator of the Kerbal Space Agency. You're in your office. Roche is a small moonlet orbiting Eve, which is a planet--"

    "I know what Eve is, you condescending--"


    "Okay, okay! Anyway, Roche is a small moonlet orbiting it, just discovered a few months ago. Around the same time, we sent a mission out to investigate it, and determine whether it's worth further exploration. The answer was a resounding yes, but they somehow managed to ram directly into it whilst doing their departure burn... and now they're stranded in Eve orbit"

    Joseph seemed to snap back to reality at the mention of several technical terms. "Well? Draft up another mission, Bill! Hell, this time let's bring that boulder home so we can study it without spending so much."

    "Uh, yes sir..."


    -

    After a bit of walking, Billy arrived at the engineering department. He entered the front door, climbed up atop the secretary's desk and addressed everyone present:

    "Okay, listen up everybody! We've got a new plan, direct from Administrator Kerman. We're going to haul Roche back to Kerbin orbit for future studies."

    Someone coughed. Somebody else dropped a coffee cup. This was gonna be huge.


    Rendezvous with Roche!





    As the prologue suggests, Roche is a tiny asteroid that's been discovered orbiting Eve! It's suspected to be a fragment of its surface, thrown off by an ancient asteroid collision. Now, you've been tasked with retrieving it, and returning it to Kerbin orbit. Weighing 600 tons, it's not going to be easy to move. We've developed a magnetic asteroid stabbing device, which will firmly attach to any metallic areas of the object. Luckily, Expedition 1 managed to paint a bright red X over an especially metallic area before they met their horrible fate. Now it's just a matter of stabbing it with the provided Asteroid Stabbing Utility and bringing it home! Also included is a cubic chunk of a Neutron star that happens to weigh exactly the same as Roche, useful for delta-v calculations using Kerbal Engineer or MechJeb without having to actually fly all the way to Eve.

    Criteria for mission success:


    1. Roche does get hauled from Eve orbit to a Kerbin orbit of under 300km.
    2. Roche does not enter any planetary atmosphere (this would greatly damage its otherwise pristine surface) Note: A large heat shield stuck in front of it allows you to ignore this restriction, so long as you don't scorch any part of Roche.
    3. Roche does not impact any planet, especially Kerbin (this would also damage it)


    Optional objectives:


    1. Recover the stranded crew of Expedition 1 and bring them home.
    2. Place Roche in an equatorial, circular (no more than 5km difference between periapsis and apoapsis) orbit around Kerbin.
    3. Orbit Roche around another body besides Eve before bringing it back to Kerbin. For science.
    4. Do the entire mission in one launch, with stock parts. This will grant you a Kerbal X-Prize Scratch-n-Sniff Sticker.


    There are few guidelines to this challenge - this is more a free-form exercise in performing the difficult task of relocating a 600 ton space boulder. Mods are allowed, but of course the most impressive relocations will be the ones done with only stock parts, or parts balanced to stock standards! I recommend using www.imgur.com to create an album of images to showcase your mission.


    Now, good luck, Kerbonauts! I look forward to seeing your ridiculous methods of relocating this huge space boulder.



    Download the scenario and parts
    > RendezvousWithRoche-update1.zip <

    IMPORTANT: Roche is classified as debris*, so you must activate debris in the map view/tracking station to see it!
    Otherwise, all you'll see is Expedition 1. Remember, to enable debris, move your mouse to the top area of the screen,
    and right-click on the debris button to add it to the currently visible items.
    Also, it would be a good idea to
    check what limit you have set for debris on the option screen, so it isn't auto-deleted.

    (If you want to put up with the possible bugs, an alternate version of the .sfs file is available at the bottom of this post)


    To install:

    First, open up your game data folder. (To access your game files on steam, right click
    on KSP, and hit properties. Then go to the Local Files tab and click "browse local files")
    Second, get the files from the zip to your game directory. For windows, you can just extract the zip
    directly into the KSP directory, and tell it to overwrite any files it finds. For OSX/Linux, you'll have to manually
    merge the new files, otherwise you'll delete your scenarios and normal gamedata!
    (thank you rspeed on reddit for that note).

    Please let me know if you find any bugs/problems and I'll try to remedy them.


    *The reason for it being debris is, if it's classified as a ship, the game thinks "oh boy, this thing's massive and must be important", so it merges your ship into it, and subsequently renames the whole stack as "Roche", which gets annoying. If you're okay with these problems though, and don't like it being debris, here's an alternate version of the sfs file. Just put it into the saves/scenarios/ folder, overwriting the normal one.

    Ooooooooh. A 600 ton brute of a space rock, eh? And we're supposed to move it back to Kerbin? I might very well try this.


    ....on the topic of mods, do we get points for odd methods of getting it back, even if they're not balanced? Because I already have a plan in me head but it's not exactly 'balanced'. Or 'normal'. Or even 'safe'.

    Money can't buy happiness, but it can buy a jet ski. Have you ever seen an unhappy person on a jet ski?

    Added another optional objective, the Kerbal X-Prize Scratch-n-Sniff Sticker

    Maybe I'm just being stupid, but I can't find the asteroid. I have 9 ship pieces and 1 command pod, with the original crew in, help..

    Did you install the parts included in the zip file as well as the scenario? Check your GameData folder for a RendezvousWithRoche folder. In that there should be Parts/New/ and then all the parts in the pack.

    If so, check in the VAB under the science tab for any of the parts. The asteroid's under structural, the stabber's under utility and the mass simulator is under science.

    If they are, lastly you should check your debris limit. It might be culling Roche as it's a piece of debris. If you want to keep the debris limit low you can just grab the alternate scenario file at the bottom of the first post.

    If we include a heat shield, can we then aerobrake the Asteroid in kerbins aatmosphere? The extra weight would lower the rockets size.
