Jupiter

Jupiter is the fifth planet out from Sol. It is the largest gas giant in the system and is actually two times larger than all the other planets of the Solar system combined. It is composed of Helium and Hydrogen in similar ratios as Sol itself, suggesting that Jupiter may have been on the road to becoming a dwarf star, but never achieved the mass to ignite. A Jovian day lasts approximately 10 standard hours, while a Jovian year is almost 11.9 standard years long. Jupiter is known for the multicolored bands and massive storms that are visible on the top of the planet’s atmosphere. The most well-known feature of Jupiter is its Great Red Spot, a massive hurricane many times the size of Earth that has been raging for centuries. Jupiter has more than 67 moons in total, though only the Galilean moons (Europa, Ganymede, Io, Callisto) are home to outposts that serve more as tourist destinations than actual military installations. Settlements on the gas giant are giant floating cities that grace the upper atmosphere, held aloft by massive, reinforced zepplins. Jupiter is the second largest source of tourism for the Solar system.

The combined population is 1.4 million people.

Jupiter's Moons

Europa -

Probes to Europa around the time of Mars colonization verified there were in fact, evidence of microbial life in its waters, which prompted more intensive probing which lead to the discovery of shrimp in both 'lakes' trapped closer to the surface in pockets of ice, and the bigger ocean underneath. The most astonishing fact about these translucent purple shrimp is the size, averaging around 1.5 feet (45.7 cms), with some observed cases of up to 4 feet(121.9cms). This is a large margin above terrestrial shrimp,. Their primary source of food seems to be rather large masses of bioluminescent algae, that seem to thrive in the typically low-light conditions of the waters darkened by thick layers of ice.

The ice-encrusted-ocean moon around Jupiter houses several facilities, most of them owned by Idris Incorporated and most of those are recreational and tourist attractions. Of the Idris facilities, the Jovian Jewel, a partially underwater casino/aquarium/fine undersea dining facility located closer to the south pole of Europa, is widely acclaimed for the aforementioned functions. The shrimp there are often served with the many other ingredients grown with hydroponic equipment present. Among the casino functions, it has well-watched biannual poker tournaments, and Jupiter's Red Storm themed roulette wheels.

Another facilitiy present on the moon with a large amount of prominence is a genetic research facility, the ZHRS Zhenbing, studies the evolutionary process of the shrimp and algae present on the moon, trying to determine the how and why they evolved the way they have.

Io -

As opposed to its more icy sister-moon, Io is bathed in lava and radiation, both being able to be pinned on Jupiter's influence, the former on its gravity and the latter on its magnetosphere. While the radiation and other electromagnetic interference present have made drones less than optimal in attempts to explore the moon, and the manned expeditions finding nothing worth the hassle of attempting to setup on the moon as it stands currently, it has been left largely left unmolested by human hands.

Ganymede -

Colonized in 2100 by the Cosmonaut Enterprises' Balandin, establishing the colony of Miestobra in the Zu Fossae. It's chief function was to allow engineers building settlements over Jupiter a reliable supply source. Over time it became a large source of agricultural goods from it's massive hydroponics program, even going so far as to establish a notable prominence in the Sol Alliance as a large quantity (and reasonable quality) alcohol provider, usually in vodka and kvass, a popular beverage of the first colonists there, and still today in Miestobra.

Of even larger note than the influence of Miestobra in the region and it's history, is the evidence of shrimp similar, if not exactly the same as those on Europa. They have been found and noted by geologists/miners working on establishing what caused the light, unmarked by crater terrain to the darker, more heavily pocketed areas. There are a few cases of them having been excavated along other materials, frozen in the icy crust. No alive specimens have been recovered yet, though it's theorized that there are more present in it's subsurface ocean, especially with recent evidence pointing to the existence of some kind of algae similar to that present on Europa as well.

Callisto -

Callisto is home to the SAOD Dosahobra, originally founded by Cosmonaut Enterprises and 'acquired' by the Sol Alliance after the USSR (and by extension, many of the countries in CE) collapsed financially. Now it serves as a primary port for travel to and from the Sol System, outside of use by the warpgate. The location was chosen for the potential to be used as a good location to gravity assist ships both heading to the outer and inner system. The technique is still used effectively to save fuel, especially for smaller ships.
