Die Weltensegler. Drei Jahre auf dem Mars.

Under a crisp winter sky over Stuttgart, a brilliant young astronomer dreams of bridging Earth and the red planet. Professor Stiller, a respected teacher at Tübingen, has spent years watching the stars from his private observatory, his fascination with Mars deepening into a personal quest. With the neighboring worlds unusually close—just 59 million kilometres apart—the age of soaring airships makes the once‑impossible seem within reach. His plans, painstakingly charted on scattered papers, promise a daring voyage that could finally connect humanity with the mysterious world overhead.

Yet turning ambition into reality proves fraught with setbacks. The professor’s impatient temper flares at the clumsy helpers who delay the construction of the colossal airship meant to carry him beyond the clouds. As the night deepens, Stiller’s resolve sharpens: all petty grievances are set aside, and the final preparations for the Martian departure begin, hinting at the adventure that lies just beyond the horizon.
