                                                              On   Two   Planets.

"Auf zwei Planeten"  ( ( literally "On two Planets" ) is the title of a 1000 pages novel written in 1897 by the german author Kurt Lasswitz .

The book starts with a german  expedition going to the north pole , where some members  meet beings from mars, who have builded an outpost in the polar region. In its essence the book describes the differences between cultures and their similarities and how it is possible to find a way to  make agreements ( coexistence ).

Kurd Lasswitz was born in Breslau / Germany in 1848. He studied mathematics and physics in Breslau and Berlin and graduated 1873 "magna cum laude" about drops,
"Über Tropfen, welche an festen Körpern hängen und der Schwerkraft unterworfen sind."

"His first published science fiction story was "Bis zum Nullpunkt des Seins" ("To the Zero Point of Existence", 1871), depicting life in 2371, but he earned his reputation with his 1897 novel Two Planets, which describes an encounter between humans and a Martian civilization that is older and more advanced. The book has the Martian race running out of water, eating synthetic foods, travelling by rolling roads, and utilizing space stations. His spaceships use anti-gravity, but travel realistic orbital trajectories, and use occasional mid-course corrections in travelling between Mars and the Earth; the book depicted the technically correct transit between the orbits of two planets, something poorly understood by other early science fiction writers. It influenced Walter Hohmann and Wernher von Braun The book was not translated into English until 1971 (as Two Planets, and the translation is incomplete.)"
