Geology of Mars time. This section introduces several of the larger physiographic regions of Mars. Together, these regions illustrate how geologic processes involving volcanism, tectonism, water, ice, and impacts have shaped the planet on a global scale. The northern and southern hemispheres of Mars are strikingly different from each other in topography and physiography. This dichotomy is a fundamental global geologic feature of the planet. Simply stated, the northern part of the planet is an enormous topographic depression. About one-third of the planet’s surface (mostly in the northern hemisphere) lies 3–6 km lower in elevation than the southern two-thirds. This is a first-order
The Angry Red Planet CineMagic process: "Our set for the planet Mars cost us a couple of hundred dollars instead of the thousands we had estimated". Pink also estimates in that interview that the movie "will be made at half the original cost", confirming that "Invasion of Mars" (the film's working title before its release) was a low-budget project. The "meager" $200,000 production budget cited for "The Angry Red Planet" may therefore be a credible ballpark figure. Filming for "The Angry Red Planet" began on September 9, 1959 at Hal Roach Studios in Culver City, California, only a month after Melchior and Pink completed
