Space is at the verge of a paradigm change. Earlier, mostly larger space agencies or international organizations were able to launch spacecraft. Today, the less expensive access to space increases the number of spacecraft, space-faring interest groups, and space-based research fields. The Science with CubeSats session emphasizes this new trend and highlights the possibilities and science objectives that can be achieved by small dedicated spacecraft, which can be built faster and in a more cost-efficient way than larger missions. These CubeSat missions can be either standalone or complementary to larger missions. The session solicits abstracts related to science onboard past, current or future CubeSats missions. We also solicit abstracts related to miniaturized instrument designs that can be accommodated on CubeSats as well as abstracts related to technologies and subsystems that enable science with CubeSats.
