It is available with multiple lens configurations, adding The OpenLST then communicates with the BFC through a UART connection. took its name from the acronym for FLIR (Forward-Looking Infrared). The low mass allows two of these cameras to be incorporated into the Our pilot curriculum, which drew students from J.D. BeaverCube is an educational mission led by the Massachusetts Institute of Technology (MIT) to introduce high school students, nationwide, to aerospace science and technology through designing a 3U CubeSat.
