    Because BOMBA! ... Or possibly he has a CRAZY tobacco addiction.

    It's interesting that you call kerosene horrible stuff while hoping for a rocket fueled with hydrogen peroxide or hydrazine, as both are horrible fuels to deal with. That hydrazine is the fuel used in most attitude thrusters says far less about how nice it is than it does about how terrible the rest of the monopropellants are, because hydrazine is nasty stuff. I mean, I suppose hydrogen peroxide has the advantages of being relatively non-toxic and clean-burning, but it also has the disadvantage of being WILDLY unstable. In that it breaks down exothermically(releasing heat), and breaking down with heat(among many, many other things). Which results in a vicious chain reaction as it begins to break down, heats itself up, breaks down faster because of the heat, heating itself more, in a race to the combustion point. And since it's a monopropellant, it's fuel AND oxidizer. So when it reaches that combustion point, the entire mass bursts into flame all at once. Bad in a spill, worse in a tank. That said... we Americans use liquid hydrogen and liquid oxygen for our main engines these days. If you can find a copy, I strongly recommend reading John Clark's "Ignition!: An Informal History of Liquid Rocket Propellants". It is both hilarious and educational, and written to be accessible to non-physics majors.

    Man, and I thought Tatooine was a poor place to call home. I pity any child that grows up on Pluto.

    ALL of us are moving there.

    Don't know yet. You do have a year to consider this, so I'd wait a few months and see what the consensus is after the launch sh!tstorm and inevitable growing pains have died down.

    I think I ranted during Frontier about their explaining why there's a time difference between the folks inside a space fold and the folks outside it. (I still maintain that it was dumb and inconsistent.)

    It's what NASA's New Horizons team wants, but official names are subject to IAU approval. So unless the IAU hates fun, those are "real".

    I throw it in every now and then. It's a sort of pretty-but-dumb that I find very enjoyable.

    HE'S GOT A BOBOMB!

    All I'm sayin' is if they reinstate Pluto as a planet instead of just the first and best of the Kuiper Belt, they better do the same for Planet Ceres. Man, that article makes all KINDS of factual errors. I mean, impulse drives are TOTALLY newtonian! They eject mass out one end to generate an acceleration, and use inertial damping fields to allow a large acceleration from a small force. This is more like Larry Niven's reactionless thruster, which does what it says. If they're going to get something as basic as THAT wrong, it casts doubt on everything they write! More seriously... 1. NASA carefully avoided making any claims about how or why it appeared to work. They very much did not claim it was "manipulating subatomic particles which constantly pop in and out of existence in empty space." They DID claim to also measure a thrust on what he assured them was a non-functional thruster, though. 2. And what the heck is a "standard photon rocket", anyways? Why aren't they comparing it to ion drives, which ACTUALLY EXIST and offer many of the same advantages as the alleged reactionless thruster? I am interested, and await more information, but extraordinary claims require extraordinary evidence, and "violates conservation of momentum" is a hell of an extraordinary claim. I expect to see this eventually deflated, but... he's successfully conning experts who expect a con, so it's inherently interesting even if it gets debunked eventually.

    Oh, also... The naming scheme is a little more complicated than that. http://www.ourpluto.org/pluto It involved a public, global vote/write-in campaign and a calculated effort to maintain a multicultural presence. Macross, as it happens, was "Favored by 30% of the voters from eastern Asia."

    Awww, we got a canyon? I was really hoping for a mountain.

    Why is KITT missing? I feel snubbed!

    That clay model was pretty sweet, yeah. And I too would like a Sophia 3rd/Metal Attacker. Even if it didn't do hover mode.

    That's awesome! I have a soft spot for the M-308 Gunner. Especially the big clamp that attaches the gun to the forearm. Game itself is wildly overlooked, too. Hurts to be an NES game hitting the same year as the Super Nintendo. Not even looking better than early Super Nintendo games can save you.

    Ooooooooooooooooooooooooh, he WENT THERE. It's ON now!

    Which was kinda my point. Ya know, I hesitated to link that, since Wired is not exactly in-depth journalism, but it seemed legit. Shows what I know. (I caught the part about requiring a firmware exploit and that they was a recall out to disable that exploit. I guess I just assumed this was a problem in the OEM stereo. )

    I agree with you 100%. A little wear and grime just makes them feel so much more "real".

    My understanding is neither Golion nor Dairugger XV were ever popular in Japan. Sad, but true.

    Also results in the two being different, but obviously related, toys. Which is nice, as repaints get old after a while.

    It could be a self-cleaning surface, such as titanium dioxide(which breaks many materials down with exposure to UV light). In which case, it'd maintain that just-painted look until it gets damaged. And if it's super-durable too... ... I think we actually have a good excuse for shiny, brightly-colored valks here.

    Have I mentioned I sit down every year or two and rewatch the Super Mario movie? It's terrible, but I love it anyways.

    Which is, honestly, probably a part of the problem. It strives for an attempt at realism, then does something I KNOW is crazy. Like I said, they were working with the best information they had available(I DO note the rings were made of what appeared to be exclusively water ice), and it really shouldn't bug me, but...
  24. JB0
    I DID probably come off ruder than I intended, really. But there won't be ice accumulation in a vacuum, because there's nothing to be icing the wings up. Anything that could has long since precipitated out onto something else or been blown away by the solar wind. Large asteroids don't retain an atmosphere. Not even Ceres. Ice accumulation in Saturn's rings would most likely be from running into the ice, at which point ice on the wings is probably not a primary concern.* But Pluto has an atmosphere, and the mass needed to keep any spontaneous release of water/nitrogen/methane/carbon monoxide vapors around long enough to start accumulating on planes. So weapons fire impacting the ground would rapidly make atmospheric conditions favorable for icing. The same is probably true of, say, Europa or Tethys. *Tangentally, it really bugs me how very wrong SDF Macross's portrayal of Saturn's ring system is. But to be fair, Pioneer 11 only flew by in 1979, with the V'gers right behind it in '80 and '81. Knowledge of the ring structure was understandably scant among non-astronomers in 1982, and I can't really fault them for not knowing the rings were so incredibly thin. I SHOULD just give them points for knowing they're largely made of water ice and move on with my life, instead of worrying about the ring system being thinner than the ships hiding within it.

    I'm sorry, but FROM WHAT? In space, the VF is the hottest thing in it's immediate vicinity. And the "atmospheric pressure" is so low that any ice that DOES manage to start forming on a VF (we'll say there was a recent fold accident and you flew through a cloud) will sublimate almost instantly. Not melt. Sublimate. It will transition directly from solid to gas. That said, VFs are designed to be all-environment fighters, and capable of transition between atmospheric and space operation with no advance preparation required. And presumably they operate on a variety of extraterrestrial bodies as well. Icing could be a HUGE concern on, say, Pluto. A stray missile vaporizes a water ice mountain, and the humidity goes up enough for anyone in the vicinity to start experiencing icing problems.
