Respond Martians (1968) (part 2)

To continue with illustrations from Respond Martians (1968) a wonderful soviet space book. The second half of the book is about the planned manned exploration of Mars.

 Illustrations of early Mars probes, both planned and conceptual. Part of the preparation for manned exploration.

 So her is their vision of what manned exploration might be like:

 The possibility that the Martian civilization is still under the ground hidden from sight.

 The books ends with some nice endplates of the constellations that I wanted to share with you.  Hoped you liked "Respond Martians."
