Those of you on TS may have heard me advising people to do their dailies if they want to grow up to be big and strong.
The term "Daily" does not necessarily mean you have to do them all daily, but they are collectable from the BaseStar daily and offer a lot of XP and additional rewards. Any uncompleted "Assignments", will roll over until you complete them, at which point you can cash it in and pick up another.
Currently I get 400+ Cubits and 700 XP from each one turned in, as well as ammo and other game resources. If you want to level up and upgrade your current ship or aspire to owning a bigger one, then dailies will make that dream come true a lot quicker.
If you just want to log in and play with us when we are doing the mine protection and XP farming only, then that's fine, but try and pick up your dailies also, pretty much most of what we are doing in game will do 4 or 5 of your dailies without you actually knowing it and you'll be upgrading your ship all the sooner.
