Were Mars (the planet) and Mars (the god) essentially the same thing to the Romans?

by dave_g17

And a bonus question: From what we know of the Romans, how would they have felt about us landing spacecrafts on Mars? Would they feel as though it's an attack on Mars, the god? Did they even know the planets had surfaces and could be inhabited/landed on? What contemporary evidence on their beliefs about the planets do we have?
