To play this card game, gather your friends and form a team. Each player takes on the role of an astronaut. As you start the game, you'll be presented with missions as you travel across the solar system. Work together to complete these 50 different missions. Remember, communication is key. Talk to your teammates about strategies and plans. If you're new to the game, take it slow at first. Don't get too overwhelmed by the challenges. There's no need to rush. Keep the cards in a dry and clean place to maintain their quality. Avoid bending or folding the cards, as this can damage them. If the cards get dirty, you can gently wipe them with a soft cloth. Have fun exploring the solar system and hunting for Planet Nine!
