Disasteroid (v0.16)

Fixed that for ya.

Do you think it was literally the size of Texas? Remember it was totallynotBush saying that. There\'s nothing to indicate it wasn\'t hyperbole.

Given how generally terrible Armageddon is on the science side,I\'m inclined to believe it was every bit as large as it was claimed to be, and that the only reason it wasn\'t larger was because someone got Michael Bay to understand that we don\'t have any asteroids that are larger.

Lets just say it was part of a moon...

Can\'t even say that. In the film, it\'s an asteroid smashed out of an incredibly dense version of the asteroid belt by a rogue comet that somehow managed, in a single impact, to both hit it hard enough to send it towards Earth and hit it lightly enough that it didn\'t come apart.

From a scientific accuracy standpoint, Armageddon\'s indefensible.

Don\'t fix what isn\'t broken.

Just tried this, quite tough! Missed the asteroid by quite a bit. My plan was to catch up to it using the plan they did on 'Armageddon'.

You do realize nothing they did in Armageddon would work, it was all hollywood magic. Maybe thats why you missed it entirely.

How they caught up to it would have worked fine, so long as you had the trajectory right. Go into near munar orbit, then when within say 500 km of the asteroid, speed up as fast as it\'s heading toward Kerbin, then just simple maneuvering to it.

And the Moon just happened to be in the right place for them to do it.

That bit was luck but not against the laws of science.

As a general rule of thumb, just don\'t archive Armageddon as scientifically accurate.

It\'s introduction was narrated by the same man who narrated a documentary about how dinosaurs actually just ate each other into extinction. I don\'t put any value on its science.

[maltesh]

would shooting the asteroid with one of JellyCube\'s railguns carry enough force to destroy it?

I can now answer this question with an unequivocal 'Yes.'

Cut it a bit close this time. Less than two hours to impact.

Thank you. You ruined my save. YES I BACKED IT UP but it was causing kerbin to be just light so I replaced it with my original persistent file and heres what happens (see attachment) : Ships flashes, are transparent, sometimes disappears...

EDIT : The screenshots I took during the bug are now black with some color pixels in it !

Looks like i had 2 persitent.SFS in my saves folder, restarting the game and let\'s see

[samstarman5]

When I\'ve been practicing orbital rendezvouses, I\'d been using it as a target. If you touch its collision box with pretty much anything (and the collision box isn\'t the same as its shape, apparently), the simulation freaks out. Generally, what happened was that pieces of my spacecraft were torn off and flung away at high velocities, and most of the time, the asteroid disappeared.

Sounds like it was designed by the Space Kraken. That creature\'s nefariousness knows no bounds!

[tsakali]

can you provide the updated links to the files? I tried searching for them but couldn't find anything

[maltesh]

Done. All links in the original post should point to current forum links, and I also updated the persistence file to a v.0.16 version.

[tsakali]

thank you!!

[Maikie_G]

It seems the new persistence.sfs doesn't work. I put it in the saves\default directory, and what I got was a save with a 1 man pod on the launch pad and no asteroid.

[maltesh]

Blast it, I uploaded the wrong one. Apologies. I've now swapped it out with a new persistent.sfs file that has the asteroid in it, but I won't be on a computer that will allow me to double-check for a few hours.

[Bluejayek]

Well, I managed this first try, more or less.

I originally intended to toss an asas module at it and then dodge the asteroid, but unfortunately I missed. Therefore Bill met a rather unfortunate end for the survival of Kerbals everywhere. He will be remembered.

Supra-orbital rendezvous are really a lot different then orbital ones...

To hit it I just went into a parabolic trajectory up in its direction, to around the right height that I thought it would be at when I got there. I then burned at kerbin to catch up with it, and when i got within visible range just aimed straight at it.

[maltesh]

Well done. To my knowledge, you're the first other person to attempt the challenge that's actually managed to rendezvous with and destroy the disasteroid. I should probably do some kind of leaderboard thing. Do you remember how high you were, or how much time it took?

[Bluejayek]

I've got this screenshot that was taken a few minutes before the rendezvous. Not perfect for leaderboard, but it should be pretty close.

23:08 hours, 4855km. Seems I cut it pretty tight.

Full stock by the way, with the exception of the asteroid.

Getting it earlier then that is going to take a lot more delta-V.. Because it seems to me you need to race out to it on an escape trajectory, then decelerate all the way down.. Some thousands of extra delta V.

Of courase, you could do a straight on impact trajectory... That would take incredible accuracy though.

If I had half decent flying skills and I could actually rendezvous, I would probably have some SRBs strapped onto some radial decouplers and then I'd shoot them at the Disasteroid. Sadly I'm horrible at flying and my rockets are usually unstable/unbalanced, so I'm pretty much playing with land vehicles more that actual orbital vehicles.

[Bluejayek]

Having those extra SRB's would unbalance your craft even more. Better off with a small projectile like an ASAS module mounted in front, as anything works to destroy this thing.

I've never headed out to it on an escape trajectory. I head into an elliptical orbit that tries to put the apoapsis on the Disasteroid's trajectory at about the time that the Disasteroid will be nearby. As the google doc indicates, if you're really exact, you can intercept it at about 19 hours after launch. The mission feels like it's doable with a Munshot craft, but I've not tried it with one, as I like having more fuel and RCS than I typically build into those.

[bsalis]

Well, I decided to do this challenge. The decision of what to use was obvious. This is a job for...

lots of pics, sorry...

... i think it's time to turn around to face it

I missed! Oh the shame.

Look at Bill. He is all WIN!

Getting really good at hitting KSC on re-entry...

Landing gear glitched into the craft. So it was a very flat landing. The MechJeb Radial was squished. Everything else is ok.
