Planetary Conditions

Gravity, Pressure, Temperature & Volcanism

Bio-Survey Profile

Signal Summary

A planet can be biologically interesting and operationally awkward at the same time. Gravity affects landing and SRV handling, pressure and temperature define the biological niche, and volcanism can change both terrain and risk.

Good exobiology planning reads the body as a workplace, not just a payout source.

Key Concepts

Gravity - High gravity changes landing risk, suit movement, and recovery margins near rough terrain.

Pressure - Thin atmosphere pressure helps define which Odyssey biological niches can exist.

Temperature - Surface temperatures can filter species and affect search expectations.

Volcanism - Geological activity can add terrain complexity, hazards, and interesting overlap with biological regions.

Field Notes

Check gravity before committing to steep approaches or landing in rough terrain.

Daylight is a condition too: the same species can be obvious at noon and nearly invisible near nightfall.

When ED:CS has body condition data, it can flag worlds that are promising but operationally slow or risky.

Signal	Value	Use
Landing risk	Gravity	Higher values reduce mistake tolerance.
Habitat filter	Pressure	Works with composition and temperature.
Terrain cue	Volcanism	May indicate rougher or more complex landing zones.
