Vanderlei Martins, a professor of physics and researcher with the Joint Center for Earth Systems Technology (JCET) joined Sheilah Kast on Maryland Morning to discuss his cube satellite or CubeSat project. Martins is working with students, other professors and NASA scientists to build the backpack-sized satellite. Martins plans to use his tiny satellite to study the role of aerosols, particles in the atmosphere, in cloud formation. Aerosols, he says, are essential for forming clouds. If there weren’t any aerosols there wouldn’t be any clouds.
