Methods for improving the microgravity environment onboard automatic spacecrafts for microgravity investigations

It is shown that none of the domestic spacecrafts on which microgravity experiments can be performed satisfy the requirements for experiments on the physics of liquid and space materials science by the level of their onboard microgravity environment. The necessary level of microgravity environment for such experiments is ∼10−7 g 0. Procedures for decreasing the microgravity onboard a prospective spacecraft intended for microgravity studies to a level necessary level are proposed.
