Worlds

Mars

Mars is the easiest of the worlds. The CO2 in the atmosphere makes it easy to grow plants. 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.

Temperature	None
Pressure	None
Solar Energy	100% Earth

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°

Atmosphere

Element	Concentration	mol
Oxygen	100%	640

Vulcan

For those looking for a harder challenge, Vulcan should fit the bill. The atmosphere is mostly hydrogen (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°
