5-year cruise to Jupiter to begin

5-year cruise to Jupiter to begin

The launch window for NASA’s next mission, one the agency is calling a “five-year cruise to Jupiter”, opens next week, and scientists are hoping it will answer some giant questions about the giant planet.

Juno, named after the god Jupiter’s wife in Greek and Roman mythology, has been in the making since the early 2000s. In the ancient Roman stories, Jupiter, the god of the sky, pulled a veil of clouds around himself to hide his mischief, and only his wife was able to peek through and see him as he truly was.

The Juno mission has been designed to do the same thing. Set to analyze the planet’s atmosphere, gravitation, and magnetic fields when it reaches Jupiter in 2016, it is the second mission within NASA’s New Frontiers Program. The first was a mission to the Plutonian moon Charon, that launched in 2006.

The origins behind the planet’s name and nicknames represent a long time fascination with the immense alien sphere. The largest planet in our solar system, it’s often called the “Giant among giants,” but the real appeal of the planet is not limited to its enormous size. The “Great Red Spot,” famously seen in photographs taken on some of the earliest Jupiter missions, has been a point of scientific curiosity for decades.

The spot itself is a spinning storm, much like a hurricane, called an anti-cyclone. An anti-cyclone is a high-pressure storm, meaning it rotates against the Coriolis Effect. The Coriolis Effect can be thought of as the apparent deflection of winds along a planet’s surface. In the northern hemisphere of a rotating planet, winds are deflected to the right as they approach the eye of a hurricane, creating storms that spin counter clockwise, and in the southern hemisphere, they spin clockwise. For example, a weather system rotating clockwise in the Earth’s northern hemisphere would be a high-pressure system and considered anti-cyclonic.

Sustained by Jupiter’s tremendous heat, much like hurricanes are sustained over the warm oceans, the red storm on Jupiter has existed for as long as humans have been observing the planet and is large enough to contain three Earths within its boundaries. Some speculations suggest that the color of the storm is due to phosphorous compounds within the atmosphere, but that has yet to be confirmed. If successful, the Juno mission will be able to prove or disprove that theory and give scientists further insight into the planet’s formation.

    As much as I'd love new pictures of Jupiter, determining whether the Red Spot is red due to phosphorous compounds is not exactly a very compelling reason to go. I hope they've got a lot more packed into that craft.

      The mission is WAY more cooler and beneficial than this article portrays. The more we learn of other planets atmospheres, the more we understand our own. Since the atmosphere is the "ocean" we live in, it's quite exciting!

      All space missions are good, all space missions are worthwhile. Irrespective of the cost, humanity should be sending dozens of probes, satellites and manned missions to the planets and beyond to gain as much knowledge as possible about the universe we inhabit.

      Well if you need a more practical reason for space exploration, how about the fact that we are crossing 7 bil humans on earth and soon will run out of space on earth . Unless we start on soilent green, we would run out of food too. Also, we are still extremely dependent on fossil fuel that will run out in the next century and need alternate source of energy. All these can be solved by space exploration. We may get to harvest minerals, etc from other planets, or find alternatives to what are available on this planet. Heck, if nothing, research that goes into building these crafts will further humanity itself. Space exploration is almost a must in this day and age

      July 29, 2011 at 8:28 pm |
      • cam

        Sorry, Snow, The solutions to our earthly shortage problems will not be found in space. To bring back minerals and energy from other planets, etc. would be insanely expensive. Mess up this place and move to another? Do you have any idea how far it would be, how long it would take, how much it would cost to move a few humans and all their stuff to another habitable planet–that is after one is found? We must begin solving our food and energy problems by reducing the earth's population and our dependence on fossil fuels. If we don't, either war or disease will do it for us. Not as glamorous as exploring space but much more realistic.

    "The first was a mission to the Plutonian moon Charon, that launched in 2006."

    New Horizons is not just a mission to Charon. The mission is to study Pluto and its moons - Charon, Hydra and Nix - and an attempt will be made to fly past other Kuiper Belt Objects if any are found near its trajectory.

      "....Pluto New Horizons mission, launched in January 2006 and scheduled to reach Pluto's moon Charon in 2015." http://www.nasa.gov. I dunno, but that seems like it contradicts you pretty hard. Do some research next time, kiddo😛

        Are you NUTS! You need to do some research yourself!!!! Here's the official site http://pluto.jhuapl.edu. New Horizons is a mission to study Pluto and its moons, not just its moons. In fact, when the mission was first conceived there was only 1 moon. Then, the scientists I work with discovered Nix and Hydra, and now they've discovered a 4th moon yet to be named. I am a senior engieer on the mission. If you doubt what I say, just ask the mission Principle Investigator Dr. S. Alan Stern. You can find him on Facebook and Twitter.

    This is supposed to be an article about the mission, but they only devote one sentence to it. The rest of the article is about Jupiter's red storm and Greek/Roman mythology. Can we get the cost, objectives, specs, timline, what we hope to learn, etc? What a waste of an article...

      Yeah, and they got the mythology wrong (Juno is the wife of Jupiter in Roman mythology. In the Greek, it is Hera and Zeus, respectively). This so-called science journalist is a joke–as evidenced by her article about the Dawn mission to Vesta in which she demonstrates that she doesn't know the difference between the birth of our solar system and the Big Bang (hey, what's nine billion years between friends?). Time to go back to the Hollywood or sports beats, Ms. Foreman–you're in over your head.

    I love how, for an article dedicated to space research and exploration, people are seriously getting worked up and annoyed with each other over the governmental economic disaster. I'm not saying that it isn't a big deal – it certainly is. However, can't we all just chill out and be excited about a really neat and possibly groundbreaking scientific opportunity? Like someone smart pointed out earlier, the money for this project was spent YEARS ago, so if you all want someone to be angry at, be angry at the president (although, it wouldn't have necessarily been his call) whose term this fell under.

    If you all really want to argue childishly, go to the MANY articles regarding the Obama/Boehner plans. Goodness.

    From reading the comments, people here seem to be completely ignorant of this Mission. New Horizions wasn't started last week on a whim, it was created in 2006 by your Lord and Savior Gee-Dub. So if you all idiots have a problem with how much this mission costs, then blame The Dubaya; Because that money was allocated to NASA 5 years ago.

      Without a doubt, the US needs a military presence to maintain our freedom. But there are any number of other "free" countries on this planet who are spending one-tenth per capita on their military that we are. Of course, they're not trying to turn a worthless section of Asian mountains peopled by nomdic tribes into a democratic society at the cost of several hundred billion per year. And they're not trying to (? what are we trying to accomplish in Iraq?) to a country that shouldn't even be a country – blame the Brits for that one – they "created" Iraq after WWI from three peoples that never should have been together. So yeah, we need a military – just not the one we have.
