text: Therefore, Is the face on Mars created by aliens or is a land formation? The pivtures explain nothing but that it is a land formation. Why? Their is no evidence that it was created by aliens nor anything else. The only way that it would've been created by aliens if NASA's had proof that there were some type of tracks of aliens. They didn't have anything so it leads to one solution. IT has to be created by sand storms and craters.        In "The challenge of Exploring Venus" The author suggests that studying Venus should be pursued, despite the dangers it brings. After evaluating the passage I do not believe that the author supports this idea well. In multiple paragraphs he states that Venus has a harsh enviorment, makes collecting information from venus seem impossible, and does not give enough evidence as to why we should explore Venus and the knowledge that could be gained.
