Mars is in the spotlight because can use our current technology to go to Mars and explore it, and we can amass resources to go there and conduct a maned mission. I'll agree that Europa and Titan show more potential for life but how can we stop focusing on Mars when NASA hasn't even really begun to focus, Mars is the next Apollo 11, if we can find life on Mars we'll be able to say confidently that life is the rule and not the rarity.
I totally agree with you! it would be cool if we could focus more on Europa or Titan, but for now they're simply too far away... and that's why Mars is getting so much attention, not to mention that it's probably the best candidate for life in the Solar System.
