Juno Jupiter Mission Report

Juno is a NASA space mission which will last 6 ½ years and aims to improve our understanding of the solar system's beginnings by revealing the origin and evolution of Jupiter. Juno is a NASA space probe (figure 1) orbiting the planet Jupiter, since entering its orbit on July 5th, 2016, the prelude to 20 months of exploration. Juno will orbit Jupiter 37 times and come within 4,200 Kilometres of the planets top clouds . Juno was launched from Cape Canaveral Air Force Base on August 5, 2011, as part of The New Frontiers Program, a series of space exploration missions being conducted by NASA with the purpose of revealing more about the Solar System . Specifically, Juno will be used to determine if and how much water is in Jupiter’s atmosphere, measure composition, temperature and cloud

A spectrometer operates by taking in light from a source, breaking it up into its components based on wavelength and turning it into a digital signal for analysis. In order to measure the magnetisation, strength and direction of magnetic fields on Jupiter, A vector magnetometer (MAG) is used and calculated by using the Pythagorean Theorem . The Juno orbiter uses radio waves to determine and locate gravity fields by using a gravity/radio science system (Gravity Science), by observing the Doppler shift . The Doppler Effect can be described as the effect of moving waves in which there is an upward shift in frequency as the source of the sound approaches, but a downward shift in frequency as the source recedes . In order to understand interactions between the magnetic fields, magnetosphere (the region surrounding an astronomical body in which its magnetic field is the predominant effective magnetic field), and atmosphere, a radio and plasma waves sensor (WAVES) is used. This occurs by measuring electric and magnetic fields as well as the radio waves. These
