Highest Altitude Achieved by a Kite - The classic record is 31,955 feet by a train of 8 kites over Lindenburg, Germany, on August 1, 1919. Single kite altitude record has been satisfactorily established by Richard Synergy, who flew a large delta to 13,609 ft above ground level near Ontario, Canada in August 2000.

Seriously, after our rocket got us out of the earth's air, we use
another kite, using the solar wind. . .
Solar sails (also called light sails or photon sails, especially when they use light sources other than the Sun) are a proposed form of spacecraft propulsion using large membrane mirrors. Radiation pressure is about 10-5 Pa at Earth's distance from the Sun and decreases by the square of the distance from the light source (e.g. sun), but unlike rockets, solar sails require no reaction mass. Although the thrust is small, it continues as long as the light source shines and the sail is deployed. In theory a lightsail (actually a system of lightsails) powered by an Earth-based laser could even be used to decelerate the spacecraft as it approaches its destination.
