Day 1: My progress in steemnova.

Metal Mine (Level 7)
Used in the extraction of metal ore, metal mines are of primary importance to all emerging and established empires.

Crystal Mine (Level 4)
Crystals are the main resource used to build electronic circuits and form certain alloy compounds.

Deuterium Refinery (Level 2)
Deuterium is used as fuel for spaceships and is harvested in the deep sea. Deuterium is a rare substance and is thus relatively expensive.

Solar Power plant (Level 7)
Solar power plants absorb energy from solar radiation. All mines need energy to operate.

Robot Factory (Level 2)
Robotic factories provide construction robots to aid in the construction of buildings. Each level increases the speed of the upgrade of buildings.

Shipyard (Level 1)
All types of ships and defensive facilities are built in the planetary shipyard.

Missile Launcher (Available: 1)
The Rocket Launcher is a simple but cost-effective defense.
