Juno is NASA’s spacecraft that was built by Lockheed Martin. Juno was originally launched on 5th August 2011 and the journey completed after a five-year travel on 5th July 2016. The main aim of Juno is an investigation about the massive radiation belts of Jupiter. It is also to study about the interior of the planet to gauge how our solar system evolved.
Juno is made for measuring the atmosphere of Jupiter, the magnetic fields, temperature, composition, gravity, cloud motions amongst others. Juno is also made to study the northern and southern lights of Jupiter, also known as auroras.
THE END OF JUNO
Juno is expected to end its mission in February 2018 and die inside Jupiter. Juno is not expected to meet its end in one piece owing to the increasing chances of damage caused by radiation that surrounds Jupiter.
Once in every 53.5 days, Juno takes measurements and brings the probe near 5000 kilometres of Jupiter’s poles. Before Juno, no other spacecraft had managed to get close enough to observe Jupiter’s poles. There are anticyclone and cyclone storms that brew around the poles, giving it a look of meteor crater while being the atmosphere.
SOME INTERESTING FACTS
Jupiter is full of mysteries. The more scientists try to unveil, the more perplexing it gets.
- Auroras on Jupiter are known to be the most powerful aurora of the entire solar system. After the measurements were recorded by Juno, there was an unexpected power source that generates the cosmic light shows.
- True to its name, Juno spacecraft carries Goddess Juno’s Lego figure that holds Jupiter with a lightning bolt along with a magnifying glass. It also contains a miniature Lego version of Galileo, who discovered Jupiter’s four of the largest moons.
- NASA’s Juno spacecraft obtains its power from solar energy since it has three giant solar panels for absorbing energy from the sun. This makes Juno the only spacecraft to reach so far in the solar system by using solar energy.
- There is the presence of huge cyclones near the mysterious poles on Jupiter and the auroras on Jupiter are different from Earth’s. Earth’s auroras are a result of solar wind slamming into the atmosphere which creates a glow.
- Data gathered by Juno has revealed the presence of an abundance of water and ammonia deep within Jupiter’s atmosphere. However, the ammonia abundances have varied from place to place.
