Construction of a high tower to the stratosphere was first proposed by Canadian Thoth Company. Because of its enormous scale, people are hesitant to implement the project immediately. This paper proposes several next steps to its realization. Fundame

The existence of a platform at the stratosphere is expected to be the role to gain a foothold in space. When the platform is employed airship in, it is transported by advection due to its light-weight body. Thereupon, a mooring of platform is reasona

A station-keeping platform in the stratosphere can be a novel foothold toward spaceactivities. If the platform is conformed as free-ight LTA vehicles, there are possibilitiesthat they may be blown away by the atmospheric advection due to its free-igh
