A storm rolls in and everyone bunks down to let it pass. Days pass and still the storm rages. As it finally abates you head outside to assess the damage and you see that your communications dish is damaged. In fact, it's gone. You've lost all communication with Earth and the other crews on Mars. You need to quickly work out how to reestablish this - you can't survive this harsh landscape without contact.
