Jump map from Travellermap.com

Tawa's Moon is an icy, barren vacuum world, with no overt population, government, or law level, which would warrant hazardous environment precautions if anyone lived here.

• Its surface is ice-capped with little or no atmosphere and nearly all of its water frozen.
• This world could be populated by a determined group if they had an inclination to do so...
• It is an unclaimed Non-Aligned world located in the La Grone Subsector of Iphigenaia Sector.

• It is a main world which is a satellite of either a gas giant or another world.
• Vacuum worlds have no climate, but experience extreme differences in temperature between direct starlight and shade.

Description (Astrography & Planetology)

Tawa's Moon is a binary star system.

• Both are red main sequence stars.
• They are close companions.

System Data

The worlds of the system have been surveyed. They consist of:

• The mainworld.
• x4 secondary rocky worlds.
• x3 gas giants.

Mainworld Data

Tawa's Moon is a satellite of a gas giant.

The mainworld and its gas giant primary orbit within the outer system.

• They receive very low levels of stellar energy.

• They orbit just beyond the stars Jump Shadow.
• An insidious atmosphere superterran secondary world orbits within the habitable zone.

Mainworld Size (S)

Tawa's Moon is a Small World between 2,400km and 4,000km in diameter. The world has low gravity between 0.1G and 0.17G. The horizon will appear about 2.5km away.

Mainworld Atmosphere (A)

Tawa's Moon has a pressure of less than 0.001 atmospheres which requires the use of a Vacc Suit. TL–8 or more advanced survival gear is required to settle this world.

Mainworld Hydrosphere (H)

Tawa's Moon has 05-15% of its surface covered by ice, either in vast sheets or contained deep within craters or fractures on the surface. Wilderness refueling is possible. Water for the inhabitants can be got by mining and melting ice.

• The surface of the world is composed of a crust of ice many kilometers thick.
• Much of the surface is cratered and covered in regolith and thick dust of meteoric origin, leaving only around 10% of the icy outer shell exposed.
• Below the outer icy shell is a world-ocean of liquid water.

Mainworld Geography and Topography

No centrally held map of the world exists within AAB Library Data records.

• Locally, detailed maps may be available.
• Verified updated charts are constantly sought.
• Detailed survey data commands premium prices.

Native Lifeforms

Extensive sub-ice native life occupying a variety of ecological niches.

History & Background (Dossier)

Tawa's Moon is a frontier, a wild and lonely place that rarely sees visitors. Many of the planets and moons within the system have never had an intelligent being visit them.

• Information about the system is limited.
• The resources of the system are largely untapped.

The system is unpopulated.

• Commercial traffic is extremely rare: the system sees very few visiting ships.
• Commo only picks up natural background noise and static.
• There are no active navigation beacons.
• Vessels are unlikely be operating among the other worlds and moons that make up the system.

Note that social data, though only 40 years old, may be out of date: previously undocumented groups may now inhabit the system and maintain their own culture, forms of government, and systems of law.

• Verified updated data is constantly sought.

World Starport (St)

Tawa's Moon does not have a starport. The Class X Starport is an indication that no starport exists in the system. There are no facilities or services available, and no site marked for landing.
