The debate about mars having canals and cities was only put at rest when nasa put a spacecraft near the planet and got pictures of the landscape. In 1976, nasa landed viking 1 and viking 2 on mars to evaluate the planet. Since the failure of phobos 1 and 2 (sent by russia) and mars observer, they stopped sending explorers to mars for 20 years until in 1997, they sent pathfinder and its rover sojourner.
