Those claims can no longer be dismissed on the basis that the objects are too small to have been alive. It seems that searchers for life on Mars will need to be equipped with devices that can detect organisms as small as nanobes. Robotic exploration of Mars Professor Ray Jarvis from the Intelligent Robotic Research Centre of Monash University described his experiments with a Russian-built miniature Marsokod rover using simulated Mars terrain. The center is applying recent advances in computer science to control the rover, which is a proven robust mechanical design. Despite the great progress with robotics in recent years.
Robots are no substitute for a human on Mars.
Dr. John Webb, of Latrobe University spoke of his experiences in Antarctica. He showed photographs of gullies caused by the melting of permafrost in Antarctica that look like gullies on Mars . Gullies on Mars, thought to be carved by water. Webb cautioned about the psychological stresses on people living in harsh, remote environments. People start out as friends but often tensions build up after weeks of isolation.
