Habitable Worlds Survey is the most common event chain in the game, happening to every empire that's not  Gestalt Consciousness.

Each Special Project requires a science ship and takes 180 days to complete.

### Habitable Worlds Survey

 *We now know without a doubt that a thriving biosphere is not something unique to [homeworld name]. Both the scientific community and the public at large are eager to learn more about the various forms of alien life found throughout the galaxy.

Efforts to catalog the life forms we encounter are already underway, but our xenobiologists have urged us to focus our planetary survey efforts on habitable, life-bearing worlds.*

* Discovered alien life

* Adds a counter for surveyed habitable worlds in the Situation Log

**We have more important matters to focus on.*** Unity Gained:  100-500

### Survey Completed

 *Through our surveys of habitable worlds, our biologists have collected a vast amount of data on alien life forms. Many of our older theories on the development of life have been disproved, and our scientific community has had to build new models from scratch!

Our most interesting findings are being displayed at the newly dedicated Museum of Exobiology on [capital name]. The public is enthralled, and many donations have come in to aid in the continued search of strange life forms.*

* Society Research Gained:  1000-100000
* Energy Credits Gained:  100-1000

### Alien Specimen Procurement

 *The director of the Museum of Exobiology on [capital name] has issued a request for the procurement of several live alien specimens. These creatures were spotted on surveyed habitable worlds, but they are difficult to capture. It will require the full resources of a Science Ship for a lengthy period of time.*

* One of each of the 9 base habitable planets was surveyed

* Issues 7 special projects on 7 random surveyed planets

### Zulcor Swarm Secured

 *The zulcor are swarming insect analogues, unusual both for their large size and the fact that they are lithovores, feeding off rocks and minerals in the ground. One of the shuttles belonging to the [science ship name] sustained serious damage when it inadvertently passed through a large swarm and several zulcors began to feed on its hull.

The construction of the special containment facilities required to hold these creatures has already begun at the Museum of Exobiology on [capital name].*

**Excellent.*** Society Research Gained:  350-100000

### Specimens Secured

 *All of the specimens asked for by the Museum of Exobiology have been secured. The museum has grown to a massive facility, where artificial gravity generators and atmospheric processors are used to simulate the environments of over a dozen worlds.

Visitors are journeying from all across the [Divine Federation] to see its wonders!*

**Excellent.*** Society Research Gained:  1000-100000
* Energy Credits Gained:  100-1000
* Influence Gained:  40-100
* Unity Gained:  150+ (no limit)
