Mars Exploration Edition
Mars has intrigued humanity since we first saw it in the night sky as a star-like object. Initially, the planet's crimson tint distinguished it from its gleaming siblings, each captivating in their way, but none forming a ruddy arc across Earth's skies. Then, in the late 1800s, telescopes revealed a fascinating surface replete with patterns and landforms that scientists initially mistook for evidence of a busy Martian civilization. We now know that Mars is devoid of artificial structures. However, we have discovered that the arid, poisonous planet we see now may have been as livable as Earth until 3.5 billion years ago.
