Discuss the possibility of life on Mars. Will extremophiles prove useful?  Can you explain the upper-temperature limit to life unrelated to the stability of proteins or nucleic acids? How influential is microbial activity on the geological processes of mineral formation and deposition compared to biological processes? Can you argue both sides? What are the challenges and advantages of the use of extremeophiles in industrial or bioremediation applications?
