NASA Mission to Jupiter to Unlock Secrets of Planet Formation
A space probe carrying some Lego astronauts is on a five-year trip to Jupiter. The Juno mission launched without a hitch on August 5 and began its journey to the largest planet in the solar system.
With the end of the 30-year space shuttle program, the new face of NASA is space probes not astronauts. Messenger is circling Mercury. The Mars Reconnaissance Orbiter is searching for signs of water on the red planet. The Dawn space probe is orbiting Vesta, a large asteroid. And the New Horizons deep space probe is racing toward dwarf planet Pluto.
And now, the Juno Project is sending a solar-powered probe to figure out how Jupiter came to be. There it will try to find a solid core in the center of the gas giant and it will study its clouds to try to figure out how the planet formed.
Juno’s science mission is:
After Juno arrives in 2016 it will circle Jupiter 33 times over the course of a year and then the $1.1 billion space probe will de-orbit (or crash) into the gas giant in 2017.
“We’re looking for the recipe about how the planets are formed. And Jupiter holds the ingredients.” — Rick Nybakken, Juno Project Deputy Manager

Correction of Formation Jupiter Planet
Planets, satellites, and comets are a part of our solar system. They have certain mass, radius and volume. The correlation between radius and mass, we should make the equation :
m^ a = r^ b
The equation above can be made to become :
a log m = b log r
or
b / a = log m / log r
The correlation of radius and mass of the solar system can be this table :
Radius of Earth : 2.6109; Venus : 2.4773
Mass of Earth : 18.181818; Venus : 14.818181
log m / log r = 2.996977
average = 3.00
*) Venus and Earth are planets, which radius and mass of Mercury = 1
Average 2.996977 or 3.00, therefore comparison between square power of radius with mass is three compared one. To make clear the comparison can be showed correlation between radius and mass.
From table above can be concluded that the mass equal with the radius power three. Can be wrote :
m = r^3
Formation of Jupiter Planet
Jupiter planet is a giant planet. This planet has density 1.33 and diameter 142,000 kilometers. By using a rule above can be calculated that radius of Jupiter planet.
Mass of Jupiter, m = 317.8 (Earth = 1)
Then radius of Jupiter ( r )
= 317.8 ^ (1/3)
= 6.824 ( Earth = 1 )
= 42,500
= 42,000 kilometers
Thus Jupiter planet has diameter 84,000 kilometers or radius 42,000 kilometers and density 5.2 ( water = 1 ). I thought that the planet from iron or stone like Earth.
Do you agree?
