Terra Firma

الموسم 1، الحلقة 2: At first we were alone on Earth, living in the shadow of the volcano and in fear of the earthquake. We watched Mars and Venus wander in the night sky, and wondered if the ground on those worlds shook and spat fire. Would these planets share our landscapes of mountains and valleys, of continents drifting across oceans of magma? This is the story of the pioneering missions to our neighbouring worlds, of our first glimpses of their awe-inspiring terrains. From the giant lava plains of Venus to the volcanoes on Mars that dwarf Mount Everest,Terra Firma takes us on a journey of exploration around the rocky planets and on to the distant icy moons of Jupiter, Saturn and beyond.
