Clear cut case: To get to the Oil, you have to drill through Rock, which is then sold. If you dig less oil, there's obviously less available rock to make songs out of. QED.

The top songs are between '64 and the late 70's. When baby boomers were just being young adults or teenagers. That can't be a coincidence.

The good news is that the US is now producing more oil, so maybe the music will finally get better again. We've had enough Justin Beiber, already, so drill, baby, drill!

Let's do the math.
Assuming it's spherical enough, a 100m comet is 4 million cubic meters.
Assuming it's all ice, that's 4 billion kg of water.
About 800 kJ per kg to heat it up to melting point from the temperatures of space (-200*C, first figure that comes to mind).
For 4 billion kg, that would be 0.79 megatons of heat to heat it up.
Then, melting.
334 kJ per kg to melt the ice into water.
Additional 0.31 megaton to melt it.
So, we're only talking about 1 megaton worth of energy to melt that comet (if i didn't drop a few orders of magnitude somewhere along the way).
Plausible, i would suspect, with a big enough engine and good thermal insulation.
Quite plausible if you use the comet's own material for the reaction mass.

A quote from the Velcro Rockets document:
I don't know how to find/make/determine these coordinates (bolded for emphasis). Does anyone know any documentation/explanation that could help me with this?
I don know that these coordinates are used to determine where to place something (rocket exhaust, camera, payload), but I just don't know how to get these coordinates.

I think, there would be at payload a 0 meters along the x & y coordinates and 22.25 meters up from the bottom of the rocket?
You should be able to plot them out easy if you've got ar81's meshwizard. Goodness knows I've used it quite a bit, it's something to have in the toolkit.

This is why I love the forum so much. Questions like these get asked. :thumbup:

I know, right?
I took a quick look at meshwizard and it seems to be capable of what I need it to do, unfortunately it's telling me that "MSVBVM50.DLL" is missing from my computer. I understand that it's part of Visual Basic, but that's about it; I have no idea how to replace it or how to remedy the problem.
Darn.

Ah, this again.
Google it, download it from CNET or FilePuma, and just drop it in the same file as Meshwizard.

Or even better, from the much less sketchy Orbithangar:

If only the package included it by default :facepalm:. But that particular author has been gone since forever unfortunately.

Now it's saying that "COMCTL32.OCX" is not properly registered...but the file's in the meshwizard directory, next to "MSVBVM50.DLL"...
EDIT: Tried to register it using these instructions, but it gave me the error code " 0x8002801c". Great.

Try it again, this time with admin privileges. The error code means that it failed to update the Windows registry due to user permission restrictions.

Random comment: if armpits are also called "underarms", than why aren't shoulders also called "overarms?

I suppose because 'shoulder' isn't as impolite as 'armpit' and doesn't need a more polite alternative, or something like that.

Got it to work. Thanks!

Interesting. In German, that would translate to "Unterarm", which is actually "lower arm". I didn't know you could call armpits underarms in english.

So the energy needed to melt the comet is 0.3e6 J/kg * 4e9 kg = 1.2e15 J.
NERVA had about 1GW (1e9 W) thermal power, so it would need 1.2e4 seconds or 200 minutes to melt the comet... Can't remember if 200 minutes total burn time would still be within spec, but is definitely plausible -- LANL was building a reusable engine for Earth-Moon shuttles etc.
NB you could go jetting around the Saturn system simply grinding the ice blocks and feeding them to the engine
The ISP would be fairly low, but the propellant is free, so who cares...
