Abstract
The results are given of investigations into the possibility of determining the parameters of planetary atmospheres (the element composition and density) by measuring the spectrum of the radiation from the high-temperature gas formed by a lander when it enters the atmosphere of a planet at hypersonic velocity in the altitude range H = 70–150 km. The example of Venus demonstrates the possibility of determining these parameters under both night and day conditions of observation. The results are recommended for investigating such parameters at the time of aerodynamic deceleration in the descent of the landers.
