Small spacecraft. A new stage in space exploration, or toys in a superheated market?

Small spacecraft have made up the majority of satellites launched into orbit for several years now. At first, these were educational projects, but then applied services began to appear, which became possible due to the development of microelectronics and significant investments in a promising direction. What tasks do small satellites in space solve today and what prospects can be expected in the future? You will learn about this from Vitaly's talk.
