The Venus balloons are one of the most important vehicles to explore the dynamics and composition of Venusian atmosphere and several feasibility studies have been reported. We here propose the balloons at low altitude of 10 to 20 km floating below the cloud in the Venus atmosphere, which will make it possible to perform the study of the Venus atmosphere at low altitude together with a direct observation of the Venus surface. The atmospheric pressure is 20 to 40 atm. at this altitude, and the temperature is as high as 300 C to 400 C. The balloons proposed here are of the spherical shape of super pressure type filled by the Helium gas. The balloons are made of thin Ti alloy or reinforced by CFRP, and have capabilities to carry the payloads of weights of several kg. This type of the balloon has several merits on the weight considerations over the normal inflatable balloons with gas containers and its inlet systems.
