NASA's Orbiting Geophysics Observatory 1 spacecraft, which was launched in September 1964, is all set to return to Earth this weekend. According to NASA, earlier the satellite was believed to be an asteroid. University of Arizona's Catalina Sky Survey on August 25 observed a small object that appears to be on an impact trajectory with our planet. The University of Hawaii's Asteroid Terrestrial-impact Last Alert System also noticed the object.
