Terra Firma

Relive the thrill of first glimpses of otherworldly terrain as you join the early quest to discover the true nature of our planetary neighbours. Pierce the toxic clouds of Venus to map ancient lava flows the size of continents. Visit a Martian volcano taller than Mount Everest and head even further out into the planetary system in search of clues to the "living" geological forces at work in the most unlikely cosmic corners.
