What led the scientists to first suspect there may be liquid water on Mars? I think led the scientists to first suspect there was maybe water on mars was that the scientists needed concrete evidence to confirm the streaks that they dubbed 'recurring slope lineage', or 'RS L' were a result of flowing water. Why were they hesitant?there were hesitant because ed the scientists to confirm their earlier suspicion that the streaks are indeed caused by liquid water.
2. How did they verify the presence of liquid water? The images produced by the spectrometers allowed scientists to identify water on the planet's surface. The water appears in the summer months and freezes when the temperature gets colder.
3. The Outer Space Treaty of 1967 prevents any nation from getting to close to any water source from another planet.The use of the organic molecule analyzer is the scientist only hope of getting their hands on the water from Mars.
