Adrastea

Adrastea‏‎

Union World - SOL System

Not to be confused with the asteroid called 5 Astraea

For the moon of Jupiter known by this name between 1955 and 1975, see Ananke (moon).

Adrastea (/ˌædrəˈstiːə/ ad-rə-stee-ə; Greek: Αδράστεια), also known as Jupiter XV, is the second by distance, and the smallest of the four inner moons of Jupiter. It was discovered in Voyager 2 probe photographs taken in 1979, making it the first natural satellite to be discovered from images taken by an interplanetary spacecraft, rather than through telescopic photography.[4] It was officially named after the mythological Adrasteia, foster mother of the Greek god Zeus—the equivalent of the Roman god Jupiter.[5]

Adrastea is one of the few moons in the Solar System known to orbit its planet in less than the length of that planet's day. It orbits at the edge of Jupiter's Main Ring and is thought to be the main contributor of material to the Rings of Jupiter. Despite observations made in the 1990s by the Galileo spacecraft, very little is known about the moon's physical characteristics other than its size and the fact that it is tidally locked to Jupiter.

Adrastea is a heavy industrialised world in the Sol System focusing on the recycling of high tech scrap, such as Weapons, Arti Grav Coils, Bombs, space ship components (not engines) Shield Generators etc.

A clever business man secured the moon in 2139 for Astraea- High Tech Recycling and approached the government to recycle their high tech in a safe and efficient manner.

Today Astraea Recycling is one of the biggest High tech recycling companies in the known Universe operating more than 500 recycling centers.

More than 3.3 million Employees work and live on the Moon. More than 2000 Mega tons of High Tech scrap are processed annually.
