are small and easy to carry so they are always ready we need them. People use them to get road directions, to pictures or to call friends. But we easily forget the power smartphone microprocessors. Scientists with NASA, the American space agency, have not. April, NASA sent three smartphones into space to operate as low-cost . They were launched from NASA's Wallops Flight Facility in the state Virginia. The launch was the first test flight of the privately Antares rocket. Space agency officials gave names to the three PhoneSats, they are called. The names are ",Alexander," "Graham" and ",Bell," after inventor of the telephone.

All three PhoneSats looked like small cubes boxes. Each one was about the size of a drinking cup weighed a little more than one kilogram. At the heart of was a Google-HTC Nexus One phone. The microprocessor inside the phone as the brain of the mini-satellite-. Jim Cockrell works for NASA California. He says the PhoneSats were an experiment to find out a cellphone can serve as the

avionics for a satellite. NASA the PhoneSats operated for almost a week. They collected pictures of Earth and sent messages to ground stations. The agency says smartphones more than 100 times the computing power of an average satellite. Cockrell notes that they also have high-resolution cameras and global positioning receivers. So, the next time you pick up a smartphone, think the work of the PhoneSats ",Alexander," ""*%Graham"

and ".Bell." For VOA English, I'm Mario Ritter
