Life Within our System<br/>The field of Astrobiology has been a growing

over the years. This is the search for life in our Solar System and beyond: Astrobiology What is most interesting is the extreme lifeforms we have discovered here on Earth - called extremophiles, these "lovers of the extreme" can live in some of the harshest environments here on Earth - thus they might be the most likely type of life that we would find on say Mars or some of the moons of our solar system.
Tell us what kind of life we might discover on one of the planets/moon within our Solar System
Triton Neptune's moon- tell us the conditions there (it could be a single location on that body) and what kind of life might thrive there
are there any missions that are in the works to make these discoveries? Are these missions worth the cost? provide all references used with citations
Unique Earth (focus on one of the following aspects):
We have abundant life here on Earth. Were we just lucky? What aspects can you think of allowed for life to thrive here on Earth. (You might want to review Chapter 9 and Earth's geological history. Think of planet size, distance from the Sun, etc.) How might have impacts (comets/asteroids) played a role in encouraging life to thrive here? What would an impact mean today, how might we survive one? What does it mean when we find an Earth-sized planet around another star, could life thrive there? What would that do to our concept of how "special" Earth is? Supply your reference(s) with hotlinks along with proper citations. In addition to your topic:
include a short paragraph about the implications for finding life elsewhere (beyond Earth). When we actually make a discovery what will that mean to the human race? What will it mean to you?
