The Venetia Burney Student Dust Counter (VBSDC) is a scientific instrument aboard the unmanned New Horizons space probe that is designed to detect dust impacts in outer space. VBSDC is the first planetary science instrument to built by students. The dust counter was launched in 2006, and named later that year after Venetia Burney, the young girl who originally named Pluto. The detector works when dust strikes films of polarized polyvinylidene fluoride (PVDF), which generates an electrical charge. The space dust is then detected over the course of the New Horizons spacecraft flight out of the Solar System and past Pluto.
