Abstract

For experimental testing of a Mars balloon probe in the upper layers of the Earth's atmosphere a specified parachute system was developed, fabricated and tested in 3 high-altitude balloon flights. The balloon volumes were 130000 and 180000 m 3 with the payloads of 500 – 900 kg; the maximum flight altitude reached 32 km. The experiments showed that one-canopy parachute system with the area of 1200 m 2 has certain advantages as compared to the four-canopy system and can be used both in Mars balloon tests in the Earth's stratosphere and as a parachute system of the descent apparatus for investigation of Mars.
