Earthquakes great and small happen virtually every day on our planet. Even our moon experiences quakes. But do any of our planetary neighbors, like Mars, get shaken? Scientists don’t know, but they will soon find out. Since the 1960s, researchers have sent numerous spacecraft to explore Mars. These probes, such as the Mariner series, brought back images of craters and relics of ancient volcanoes on the Red Planet’s surface. But no one was sure what was happening inside Mars. Underground, it might well be seething with activity. Now, Thomas Pike of the Imperial College of Science, Technology and Medicine in London is designing an instrument to check for “marsquakes.”
