A little strategy.
A lot of space.

1. Play your hand. Cards cost energy. Tap a card, then Play, or drag it onto the mission table.
2. Build a spacecraft. Up to four systems stay on the board. Most come online next turn. Their orange number is how much hazard pressure they resolve; the red number is their durability.
3. Engage the hazard. Select a ready system, then the hazard. Each system engages once per turn. Tactic cards work immediately.
4. Read the next move. End Turn lets the hazard act. Armour absorbs hull damage first. A new turn refills energy, draws two cards and activates systems.
5. Bring it home. Clear three encounters. Collect data, then use Downlink or a Data Burst card to return science to Earth. Stored data alone does not count.

This is a fictional training card game. Systems do not literally fight eclipses or solar storms. All card statistics and hazards are designed for play; NASA resources explain the real engineering principles.
