Fei Xin:

  • Orbital Distance:  1.3 AU
  • Orbital Period:  0.8 Earth-years
  • Keplerian Ratio:  3.433
  • Radius:  9,317 km
  • Day Length:  _ Earth-hours
  • Atmospheric Pressure:  6.07 atm
  • Surface Temp:  1,303 °C
  • Surface Gravity:  3.2 g
  • Mass:  6.778 Earth-masses

Fei Xin is an extremely hot and volcanically active world. A thick carbon dioxide and ethane atmosphere covers an iron-rich surface with deposits of calcium.

DATA:
Active volcanic site
Profile: Shield volcano with current effusive eruption
Lava composition: Basalt flow with unknown materials

ANALYSIS:
This volcano has recently erupted. Fei Xin’s unusually strong gravity (3.2 G) means the lava flow is localized and may be valuable for study.

H-599:

  • Orbital Distance:  3.2 AU
  • Orbital Period:  3.2 Earth-years
  • Keplerian Ratio:  3.2
  • Radius:  8,920 km
  • Day Length:  _ Earth-hours
  • Atmospheric Pressure:  0.12 atm
  • Surface Temp:  426 °C
  • Surface Gravity:  _ g
  • Mass:  _ Earth-masses

With its distinctive ring, H-599 was used as a rendezvous point during the Nexus‘ early attempts at exploration. Pilots still use the term “a 99 run” for a short journey with numerous hazards.

Gong Zhen:

  • Orbital Distance:  29.2 AU
  • Orbital Period:  89.7 Earth-years
  • Keplerian Ratio:  3.094
  • Radius:  2,720 km
  • Day Length:  _ Earth-hours
  • Atmospheric Pressure:  71.69 atm
  • Surface Temp:  1,855 °C
  • Surface Gravity:  _ g
  • Mass:  _ Earth-masses

Gong Zhen is a small but scorching world, partially due to a crushing nitrogen-carbon dioxide atmosphere. Evidence suggests its icy ring was once a small comet.

Nexus; Space station in orbit around 4th/unnamed planet:

Station name: Nexus
Length: 15.47 km (when completed)
Anchorage wheel diameter: 5.3 km
Status: under construction

ANALYSIS:
Headquarters of the Andromeda Initiative, the Nexus is a massive space station designed to anchor the returning arks, process resources, and support colonists before their departure to new worlds. All new arrivals must pass quarantine.

History 

The Nexus is intended to be the hub of the Andromeda Initiative once the project reaches the Andromeda galaxy. Taking inspiration from the much larger Citadel, the Nexus contains features comparable in form and function to those found in the Milky Way station and houses the command echelons of the project.

At launch, the Nexus resembles two Wards of the Citadel joined together at the base. Upon reaching Andromeda, construction is due to commence on the station in order to give it a Presidium-like central torus and another Ward-like superstructure. The arks are to dock with the station on its central support column to provide it with extra power and storage.

The Nexus was activated a year before the Hyperion arrived in Andromeda. With its original leadership decimated in the Scourge disaster shortly after arrival, and unable to establish contact with any of the First Wave Arks, the staff on board began having disputes, this eventually led to a rebellion against the Nexus leaders, after this conflict the crew on board who had rebelled were banished from the Nexus and labeled as “Exiles“. There has also been reports of terrorist activity and sabotage from other crew members who did not agree with the senior staff on topics of survival within the Andromeda Galaxy. The krogan who were originally part of the Nexus team had been told by the Nexus leadership that if they stopped the rebels they would be given more control over what happens on the Nexus, however they were not given anything for their efforts, and so virtually all krogan left to form their own colony.

Furthermore, the first two attempts at establishing outposts both ended in disaster. Run-ins with the hostile kett, and lacking the resources and manpower supposed to be provided by the Arks, coupled with food shortages, the standing Nexus leadership were forced to cease all construction on the Nexus, and stretch their dwindling food stores via rationing.

Approximately fourteen months after the Nexus’ arrival, its inhabitants began to give up hope of rendezvousing with the other arks, but that all changed when Ark Hyperion arrived and docked with the station. Despite the Nexus leadership’s lack of faith in the success of Pathfinder Ryder, the station itself slowly began working to revitalize the Initiative, culminating in the successful settlement of Eos and subsequent first contact with the angara. The angara have received reports of the Nexus’ encounter with the Scourge prior to this, but due to their disastrous first contact experience with the kett they did not choose to immediately offer aid.

Ma Huan:

  • Orbital Distance:  94.7 AU
  • Orbital Period:  526 Earth-years
  • Keplerian Ratio:  3.07
  • Radius:  45,011 km
  • Day Length:  _ Earth-hours
  • Atmospheric Pressure:  1.60 atm
  • Surface Temp:  _ °C
  • Surface Gravity:  _ g
  • Mass:  _ Earth-masses
  • Satellites:  1

Ma Huan is largely composed of hydrogen and methane. Its relative proximity to the Nexus makes it a useful core discharge site. Plans for helium-3 skimming station are in progress.
