Depends on the amount of characters and which characters you can use.
If you're limited to 15 (this seems to be the average) you can use most of these, but some might need slight alteration.
Also, depends if you want everyone to know your blogger name is 30STM related or if you want it to be something more mysterious, that only die-hard Mars fans will get. All these names ARE Mars related, but you'll notice that some are obscure references that only Mars fans will understand. Of course you can change 'Mars' to '30STM', '30STM' to 'Mars' and certain words, as you see fit.
