The atmosphere of Venus is the very dense layer of gases surrounding the planet Venus. Venus's atmosphere is composed of 96.5% carbon dioxide and 3.5% nitrogen, with other chemical compounds present only in trace amounts. [1]
23 Ιαν 2018 · With a radius about 5% smaller, the uncompressed density of Venus works out to be nearly the same as Earth’s (Table 1), implying a similar structure and composition for the body of both planets.
The Venus International Reference Atmosphere (VIRA) model contains tabulated values of temperature and number densities obtained by the experiments on the Venera entry probes , Pioneer Venus Orbiter and multi-probe missions in the 1980s.
Venus Global Reference Atmospheric Model (Venus-GRAM) is an engineering-level atmospheric model developed by MSFC that is widely used for diverse mission applications including: Systems design. Performance analysis. Operations planning for aerobraking, Entry, Descent and Landing, and aerocapture. Is not a forecast model.
1 Ιουν 2019 · This paper presents a meta-study of existing observations of Venus' upper atmosphere and exosphere and an exospheric model of the thermal and hot atmosphere of Venus above the homopause. Mass spectra for possible future Venus missions are predicted, as for example the EnVision mission of ESA.
Abstract. This work reviews the long-term evolution of the atmosphere of Venus, and modulation of its composition by interior/exterior cycling. The formation and evolution of Venus’s atmosphere, leading to contemporary surface conditions, remain hotly debated topics, and involve questions that tie into many disciplines.
