A. From the six probes we have sent to Jupiter already, probably anywhere from 1 to 3 years. From the source shown below: "Pioneer 10 was launched in 1972 and flew within 81,000 miles (130,000 kilometers) of Jupiter on Dec. 3, 1973."

A. Well what I find interesting about IO is that it has this weird connection with Jupiter's magnetic field. Here is an excerpt from a site that talks about it: As Io moves around its orbit in the strong magnetic field of Jupiter and through this plasma torus, a huge electrical current is set up between Io and Jupiter in a cylinder of highly concentrated magnetic flux called the Io Flux Tube. The Flux Tube has a power output of about 2 trillion watts, comparable to the amount of all manmade power produced on Earth. It is responsible for bursts of radio frequency radiation long detected on Earth.

Jupiter's moon, Io ejecting material at 1000 kg/s--just want to know if i did this right?
Q. assuming that Jupiter's moon Io is ejecting material into Jupiter's magnetosphere, how long will it be before Io lose 10% of its mass? the mass of Io = 8.9319 * 10^22 kg 10% of this mass = 8.9319 * 10^21 kg time until 10% lost--> mass/rate---> 8.1319*10^21kg/ 1000 (kg/s) 8.319 * 10^18 s is what I get from doing this calculation Does this seem right? This would be much longer than the time that has elapsed from the beginning of the solar system til today. Am I forgetting something?? Thanks

A. The Voyager spacecrafts, I suppose the JPL Voyager Team gets the "human" credit for the discovery. You won't find a single person's name attributed to the discovery of the volcanic activity on Io. The first volcanic plume was imaged by Voyager I, in 1979. The discovery is credited to the entire "team" (JPL Voyager Team). Linda Morabito might be your best bet, if you *must* have a name (copied from source) "During the day, Linda Morabito, an optical navigation engineer, began to work with this picture on her computer-controlled image display.

A. on earth,W=mg--->m=W\g= 52\9.81= 5.3kg for the mass of the body and since mass is constant, so on the surface of io:W=5.3*1.81=9.593 Newtons.

A. It's geologically active. In fact, it's the most geological active object in our solar system. It has over 400 active volcanos. These volcanos spew sulfur lava reaching about 300 plus miles upwards. The lava has different characteristics than the typical lava on Earth. It can be red, yellow, green, etc. This is due to the different types of sulfur. EDIT: Just to help David out here too since some of his critique on what I said is a bit off, I'll add this little tid bit. First, Io is not a planet; it's a natural satellite of Jupiter. It does not have the characteristics of a planet. Its eruptions actually do reach about 300 miles. Here is a reference: "It has billowing volcanic geysers spewing sulfurous plumes to over 500 kilometers… [cont.]

A. as taking gavity on earth =10m/s square. weight = mg N where m -mass in kg and g gravity due to earth and N unit in newton. weight is gravitation pull by earth on a body that exists . i.e. having mass. now weight of ice=44 which is equal to mg, i.e. 44=mg here we find that mass of ice =4.4 kg. 1)mass of the ice is remain same on lo surface as it is the characterstic of body. 2)weight =product of 4.4 and 1.81 simple calculations can be done by yourself.

Asked by Angela C - Mon Mar 17 20:32:44 2008 - - 3 Answers - 0 Comments

A. Io orbits deep in Jupiter's inner radiation belts, and they're most intense and deadly along it's orbit. Charged particles in the magnetosphere are dragged around with the rotating magnetic field, which spins once in just under 10 hours like the planet itself does. They blast the surface of Io and rip away more than a ton of material from the surface every second, much of it sulfur and oxygen. This material forms a torus or ring of plasma around the planet that glows in UV radiation and eventually spreads through the whole magnetosphere. The result is also extremely high radiation levels on Io' surface and in the radiation belts. The radiation there is so intense an unprotected person would die instantly, and electronics fare no better… [cont.]

Q. What is the weight of this piece of ice on the surface of Io?
Asked by li_johnson34 - Wed Sep 30 22:10:13 2009 - - 1 Answers - 0 Comments

A. The acceleration due to gravity on Earth's surface is about 9.8 m/s2. Now weight is defined as mg (mass x gravitational acceleration) Mass, on the other hand, doesn't change- it's the same on Earth's surface as it is on Io's So simply find the mass on Earth's surface (divide 44 by 9.8) and multiply it by the new accelaration (1.81) (44/9.8)*1.81= 8.12N Considering that Io's gravity is a lot weaker than Earth's, that answer sounds about right.

A. 42 hours. Like out own Moon, Io's rotation is sychronous In astronomy, synchronous rotation is a planetological term describing a body orbiting another, where the orbiting body takes as long to rotate on its axis as it does to make one orbit; and therefore always keeps the same hemisphere pointed at the body it is orbiting. .

Asked by direct2denver - Fri May 9 02:24:44 2008 - - 1 Answers - 0 Comments

A. Since Io is tidally locked to Jupiter, it rotates with the same angular speed as it orbits. Since both periods are about 1.7 days, the angular speed of Io turns out to be 1 revolution per 1.7 days. From there you can go to whatever units you want, such as the generally more useful form of radians per second, or less commonly, revolutions per second.

A. I wonder if you even bothered to read about Callisto and Io - some very interesting things to learn about. Callisto is made of approximately equal amounts of rock and ices (water ice, methane ice, and ammonia ice), and investigation by the Galileo spacecraft revealed that Callisto may have a small silicate core and possibly a subsurface ocean of liquid water. This makes is completely different in composition from the moon. However, the surface of Callisto is heavily cratered and extremely old (just like the moon). It doesn't show any signs of subsurface processes such as plate tectonics, earthquakes or volcanoes, and is thought to have evolved predominantly under the influence of impacts (just like the moon). Io is completely different… [cont.]

Asked by soccer4life1234 - Wed Oct 10 17:55:42 2007 - - 4 Answers - 0 Comments

A. Io: Jupiter's varying gravitational pull generates friction in Io's interior, making it **extremely** geologically active and volcanic. Europa: Similar to Io, Jupiter's gravity generates friction in Europa's interior. However, in Europa's case, instead of vulcanism, the friction produces enough heat to keep Europa's oceans liquid on the inside, even though it's an iceball on the outside.
