[+] New Horizons Probe's Images of Jupiter 86 comments
SeaDour writes "The Pluto-bound New Horizons space probe, launched a little over a year ago, recently succeeded in passing through a narrow navigational keyhole by Jupiter. Using the gas giant's tremendous gravity, the craft now has a significant boost toward its final destination, shaving three years off the time it would otherwise spend en-route. As it passed through the Jovian system, the probe took some fantastic images of the neighborhood, including detailed observations of erupting volcanoes on Io, time-lapse photography of Jupiter's tumultuous atmosphere, and the faint ring system that was first discovered in Voyager photography. These new images prove the capabilities of the small probe, which is set to reach Pluto in 2015."

  • very fascinating indeed. did you guys see the pictures of the massive volcanic plume rising from Io? i remember watching Io and the 4 moons of jupiter including Ganemede from my 2.5 inch refracting telescope as a child.
    • That photograph of the plume is one of the most amazing pictures I've ever seen. It was Voyager II that first gave us a glimpse of the Loki Patera volcano on Io and that was amazing enough, but that image just takes the cake. It has a ghostly 3-D deal going on that is simply breathtaking.

    That would be a cool picture if it didn't have an ugly cheeto colored banner saying "Europa Rising".

    Oh, and that other message that says, "ALL THESE WORLDS ARE YOURS--EXCEPT EUROPA. ATTEMPT NO LANDINGS THERE."

    Only 2994 days until we reach the closest mission path point to Pluto! As official decorate-for-the-holidays time manager for Sears, I have a special talent for knowing when to begin reminding people of important events so I declare the countdown to Pluto to be on! We'll start laying out the plastic globes in 2010...

    Before the flyby, the New Horizons science team asked a bunch of us amateurs at http://www.unmannedspaceflight.com/ [unmannedspaceflight.com] to search for "pretty pictures", pictures that didn't necessarily have scientific value, but were beautiful and worth taking. Europa Rising and the Io and Europa conjunction [jhuapl.edu] were the first two returned. The others I suggested were two double shadow transits, a crescent Callisto emerging from behind a crescent Jupiter, and a crescent Ganymede in front of a crescent Jupiter.
    Enjoying my 15 minutes of fame. :)

    It has already seen Pluto! Twice, even! (one [jhuapl.edu], two [jhuapl.edu])

    What are we going all the way there for again?? :-p
      1. "We choose to go to Pluto in 2015 not because it is easy, but because it is hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win."
      2. "Because it's a really cool way to spend $675 million."
      You choose.

        ... seriously, though, the opportunity for a good gravity-assist trajectory was there now, and since Pluto is hurtling away from the sun quickly, if we don't visit it now it'll be a lot less active until our great-grandchildren get the next opportunity.
  • It's sad to me that this story has so few comments. Outer space just holds less and less allure to the populace as time moves forward. Why is that? Especially as we are just starting to get some of the really sci-fi 21st century stuff going. is the 21st century to be the last century of space exploration?

    It's the same with aviation in general, interest has been declining steadily. in 1980 there were 800,000 pilots in the US, now, just about 400,000.

    I do believe that we are losing our exploratory drive; we are becoming more decadent?...nah. We're just exploring other things. Genetics and robotics, both will help us get up there I hope.

    Well, you know what? Space is hard, and far. Maybe we just aren't ready for the journey yet.

    hopefully someday at least our robots will be - they're already doing a bang-up job.

      I mean, what's the point of going into space if all it is is dust, rocks, and craters.

      Don't forget gas! Gas and plasma and vacuum. Vanishingly little of space is actually dust, rocks, and craters, really.

      But there's plenty of gas.

      Check out the asteroid belt, next time you're in the vicinity. It's a gold mine, in every sense. The amount of wealth out there is "beyond imagination" [space.com].

      Just one moderate-sized asteroid (Eros) is estimated to contain $1,000 billion in gold [crystalinks.com] alone - more than has been mined (or indeed could ever be mined ) from Earth's crust in recorded history. Then there's the platinum and the other metals, minerals and rare earths, roughly $20,000 billion in total. And there's millions of asteroids in the belt.

      It's not just the mineral wealth that has people interested. It's estimated that maybe half of the asteroids are carbonaceous, containing 20% water and a further 10% oxygen [nss.org] extractable from other sources (good fuel source stuff). Additionally, there are significant amounts of carbon and nitrogen - in total, enough basic resources to support human life on a huge scale. It's likely going to be easier to colonise the asteroids than to colonise Mars.

      • That's all very well, but there's one very important thing that's going to be easier to do on Mars than on the asteroids - growing crops.

        The energetics of growing crops with artificial light are just horrendous; there's only one crop where that's done with any regularity because of its exceptionally high value.

        • Why do you need artificial lights to grow crops on an asteroid? Other than the vacuum (Needing stronger glass and better seams) it seems to me growing crops on an asteroid would be about the same as growing them on Mars.
        • That's probably why they'll use sunlight instead. You'd have to be pretty far away from the Sun before artifical light becomes competitive with the real thing. Still, if they're willing to grow marijuana via inefficient sunlamps now on Earth, you can bet good money that someone will grow vital crops via extremely efficient light sources. It shows that artificial light is not that horrendously inefficient.

      Because nothing has been the way we thought it would be:
      -Before we orbited the moon, everyone assumed the back would look like the front
      -Before we sent a probe to Mars, nobody knew what to expect, anything a Martian civilization to... something like the Moon. Even now Mars has many aspects to it that deny simple explanation, things like what lies more than a few inches below its surface or why it has anomalous amounts of methane in its atmosphere
      -Before we sent a probe to Jupiter, everyone assumed that the moons there would be cold, inanimate frozen rocks... rather than posessing the largest volcanoes and deepest oceans in the solar system
      -Before we landed a probe on Titan, speculation was rife about what could be there, because you just couldn't tell. Now that have a vague idea, it's weirder than anybody guessed

      If I can assure you one thing about Pluto, it will be that absolutely no one will have predicted what will be there correctly. And that's what makes it worth looking.
    • Space is boring...the whole solar system seems to be dust, rocks, and craters.

      The swirling paisely atmosphere of Jupiter, the volanoes of Io, white frost [wikipedia.org] on red Mars rocks, the rings of Saturn, the methane lakes of Titan, the spooky blue of Neptune are all quite beautiful and amazing in my opinion. And even craters [wikipedia.org] can be amazing. But easthetics are subjective and each to his/her opinion. Yes, Earth is best, but variety is also cool.

      It may be a non-planet, but none of the Kuiper belt objects have been studied yet, and Pluto is a start.

      I wish the astronomy groups would get their adjective usage right, or at least consistent. A dwarf planet is somehow not a planet, but a dwarf star is a star. Sol is a dwarf star, so does that make it not a star? That sort of dissonance makes calling Ceres a planet seem sensible in comparison. Anyway, I support the notion of not calling Pluto a planet, I'm just disappointed that they had to odd twisting of words to do it.
      • by Dr. Eggman (932300) on Wednesday May 02 2007, @08:12PM (#18965495)
        Calling the Sun a dwarf star is misleading. In terms of stars there are dwarf and giant categories, but for planets there is (now I guess) dwarf planets, planets, and gas giant planets. Our sun, is a dwarf star, but that is also called a main sequence star. Pluto is not exactly your typical planet it would seem.

        Then again, I am of the mind that says pluto should be considered a planet, since even our own and those like it are dwarfed by the massive giants by many times more than it would seem we dwarf pluto. If we're going to make these kinds of petty changes like with pluto, we should just reorganize the entire system into a single 'collections of matter' scale, starting with the particles, moving up through comets, planets, gas giants, then onto stars, nebula, galaxies, what-have-yous, up to the universe itself. And we'll give these collectives a unified naming scheme so lame and mundane yet extensable and modular that it would make even Taxonomists cry themselves to sleep.
        • I think Neil deGrasse Tyson was onto something about Pluto though, it's mostly a ball of ice that would turn into a comet if it were to ever come as close to the sun as Jupiter is. The fact that it orbits at an angle well outside the ecliptic was another problem in why Pluto didn't fit the planetary sequence very well.

          Gas giants can exist closer to the sun without problems, as witnessed by the discovery of "hot jupiters".
          • There isn't a "planetary sequence" and I bet Pluto is actually the most common type of body by numbers in the Solar System.

        It doesn't negate your point, but Triton (moon of Neptune) was studied by Voyager 2, and is quite likely a captured KBO. I imagine Pluto will look a lot like it.
