A player can exhaust a readied planet card to spend resources or influence from that card’s planet.
A player can exhaust certain readied technology cards to resolve those cards’ abilities.

If a card is exhausted, a player cannot resolve that card’s abilities or spend resources or influence on that card until it is readied.
During a “Ready Cards” step, each player readies all of their exhausted cards by flipping them faceup.
