Worlds

Mars

The thin martian atmosphere contains useful gasses for growing plants and base pressurization. Mars suffers from storms that damage solar cells and blow away loose items. The temperature is Earthlike during the day.

Moon

The Moon is a vacuum, so the challenge is to capture gases. Fortunately the Sun is at a 0° so it's easy to capture power with a simple solar setup.

Europa

Europa is a freezing hellscape. The extreme temperatures drain batteries and it takes a lot of power to keep warm. The weak Sun makes it hard to use solar. It's recommended to start with coal power.

Gravity	13% Earth
Temperature	-169 to -139 °C
Pressure	87 kPa
Solar Energy	42% Earth
Solar Angle	32°

Oxygen	100%	640

Vulcan

For those looking for a harder challenge, Vulcan should fit the bill. The atmosphere is mostly volatiles, and it's very hot. Be very careful with oxygen, because it can and will combust if it is released in the atmosphere. For that reason, the planet lacks ice, and one must trade instead of mine to obtain gases such as oxygen and nitrogen.

Gravity	34% Earth
Temperature	124 to 621 °C
Pressure	9 kPa
Solar Energy	150% Earth
Solar Angle	10°

Loulan

Loulan has a breathable atmosphere and the temperature range is not hazardous. It has ruined structures scattered across the terrain which can be scavenged for building supplies. The player starts with a hardsuit backpack and a headlamp, but without a helmet or suit and this is not a serious handicap. A jetpack is not part of the starting equipment. Battery charging is not a matter of life and death, but without batteries the headlamp will not light your way at night.

The greatest challenge is food since seeds are not part of the starting equipment. The player must either scavenge some seeds from ruins, trade, or use an Organics Printer to create them. While the gas mix is compatible with farming, the low night temperature is not, so a greenhouse must be operated at the right temperature. The easiest way is to open up the airlock during the day with warm 20 degrees air, and close it at night.
