RADIO SIGNALS FROM MARS: This week, an amateur radio operator in British Columbia picked up a radio signal ... from Mars. It came from NASA's Mars Reconnaissance Orbiter flying just 274 km above the Red Planet's surface. Such a detection is possible because, right now, Mars is unusually close to Earth.
