Transcript of Jupiter
Jupiter is the 5th and largest planet in the solar system.
approximately 143,000km wide in its equator.
Jupiter is 778,500,000km away from the sun, 5 times that of earth.
The temperature in Jupiter’s clouds is about minus 145 degrees Celsius, but the core temperature is way hotter, 24,000 degrees Celsius.
Jupiter also has a very strong magnetic field because of all the liquid metals under the clouds
it is a giant gas planet or a 'gas giant' its atmosphere is made up of mostly hydrogen and helium gas.
its surface is covered in thick red, white, brown and yellow clouds.
One of Jupiter’s famous and unique features is the great Red spot, it is a giant spinning storm, resembling a hurricane, at its widest, the storm can be about 3 and a half times earth’s diameter, Jupiter is a very windy planet.
Jupiter is so big that all the other planets in the solar system could fit inside it.
How Jupiter is and has been studied.
Jupiter has 3 rings, they were discovered by NASA’s Voyager 1 spacecraft in 1979.
Jupiter also has 62 known moons, the largest 4, were discovered by Galileo Galilei in 1610 and are called the Galilean Satellites.
Astronomers have used telescopes on earth to study Jupiter, (Galileo Galilei was the first astronomer to study Jupiter with a telescope).
Astronomers have also used telescopes such as Hubble Space Telescope that orbits the earth
NASA has sent out 8 space crafts to Jupiter, they Studied Jupiter’s surface, rings, moons and atmosphere
The most previous Space Craft sent to Jupiter is called Juno and it is still on its way, it was launched in 2011 and is supposed to arrive at Jupiter in 2016, Juno will be closer to Jupiter than the previous space crafts and will help scientists study the origin and evolution of Jupiter
Pioneer 10 completed the first mission to the planet Jupiter
Its mission Type was Flyby
Launched on 2nd March 1972, Passed by Jupiter 3rd December 1973
contact was lost in 2003 when it was 12 billion kilometers from earth.
As it passed through Jupiter's system, it transmitted Hundreds of photos of Jupiter and its moons, radiation of energy particles, magnetic radiation of Jupiter along with measurements of Jovian atmosphere.
Other Missions To Jupiter
Pioneer 11, Launched 5th April 1973
Voyager 2, Launched 20th August 1977
Voyager 1, Launched 5th September 1977
Galileo, Launched 18th October 1989
Ulysses, Launched 6th October 1990
Cassini, Launched 15th October 1997
New Horizons, Launched 19th January 2006

Jupiter rotates the fastest from all the planets in the solar system, its day is only about 10 hours long, while earth’s is 24 hours
How did Astronomers Gain Information by using Pioneer 10?
Pioneer 10 had different parts that helped scientists observe the solar system.
a charged particle instrument for detecting cosmic rays
a quadrispherical plasma analyzer for detecting solar wind particles that originate from the sun.
a cosmic ray telescope to detect data about the energy range of the cosmic ray particles as well as their composition.
A helium vector magnetometer for studying the magnetic field interaction of the solar wind with Jupiter and mapping the interplanetary magnetic field.
Meteoroid detectors to record to the impact of small meteorites striking the space probe.
and a UV photometer to determine how much helium and hydrogen there is in space and on Jupiter.
Effectiveness and Obstacles
The Pioneer 10 faced a few hurdles along its way through the solar system, its first was when it was after passing Mars, when it was trying to pass into the outer solar system through the unavoidable asteroid belt, even the smallest rocks about the size of a grain of sand could pierce through the spacecraft and break the vital systems, a rock about the size of a baseball could take out the whole spacecraft.
Pioneer 10's second hurdle was passing through Jupiter's radiation belts, Jupiter is a powerful source of radio signals and no one knew how strong the radiation might be or how deeply the zone could be entered by a spacecraft without its electronics gettting ruined.
Implications of using Pioneer 10 on the local or global community
we shouldn't use Pioneer 10 for our local or global community because it is a flyby spacecraft, so it doesn't stay and orbit the planet but just keeps going on. we wouldn't be able to use it except for examining space.
