The last four rovers that traveled to mars were named Sojourner, Curiosity, Spirit, and Opportunity. I think the next Mars rover should be named Believer and here is why. Rovers help scientists in their quest to understand what different parts of the planet are made of. I want to believe rovers will help scientists discover further opportunity for mankind. My teacher says "always believe you can," and I believe this rover will help make one small step for a man,and one giant leap for mankind!
