Multifunctional Structure Stabilizes and Rotates Satellites

Many satellites are in space to take photos. But a vibrating satellite, like a camera in shaky hands, can’t get a sharp image. Pointing it at a precise location to take a photo or perform another task is an important function that requires accuracy. Researchers have developed a way to cancel out the vibrations of a satellite by vibrating the solar panels in the opposite direction — called active noise cancellation.
