“…with a cost cap of e420 m (including launch costs but not including scientific payload, which is funded by the member states). It may be noted that the EVE team had submitted an earlier proposal, also named EVE, to ESA's first Cosmic Vision call in 2007 [7,8]. This first proposed mission, 'EVE 2007', was a large ESA-Russia joint mission with a lander and orbiter as well as a balloon.…”

International audienceThe European Venus Explorer (EVE) mission described in this paper was proposed in December 2010 to ESA as an 'M-class' mission under the Cosmic Vision programme. It consists of a single balloon platform floating in the middle of the main convective cloud layer of Venus at an altitude of 55 km, where temperatures and pressures are benign (∼25°C and ∼0.5 bar). The balloon float lifetime would be at least 10 Earth days, long enough to guarantee at least one full circumnavigation of the planet. This offers an ideal platform for the two main science goals of the mission: study of the current climate through detailed characterization of cloud-level atmosphere, and investigation of the formation and evolution of Venus, through careful measurement of noble gas isotopic abundances. These investigations would provide key data for comparative planetology of terrestrial planets in our solar system and beyond

“…Another Venus in situ mission concept, called the European Venus Explorer has been proposed under ESA's cosmic vision programme by a European-led international team. This M-class mission concept would consist of a cloud-level balloon, a short-lived lander and an orbiter, with potential added elements of drop sondes and a contributed mid-altitude balloon [39].…”

A primary motivation for in situ probe and balloon missions in the solar system is to progressively constrain models of its origin and evolution. Specifically, understanding the origin and evolution of multiple planetary atmospheres within our solar system would provide a basis for comparative studies that lead to a better understanding of the origin and evolution of our own solar system as well as extra-solar planetary systems. Hereafter, the authors discuss in situ exploration science drivers, mission architectures, and technologies associated with probes at Venus, the giant planets and Titan.

“…Various studies [6,[9][10][11][12] have been conducted on different designs of long endurance probes to explore the Venus atmosphere. The operating conditions the exploration mission vehicle will be subjected to at this altitude will still be harsh, but not as severe as the surface conditions and one can plan the vehicle to be under operation for months rather than hours.…”

Unique cooling systems have to be designed to cool the electronic components of space exploration rover, especially in places like Venus, which has harsh surface conditions. The atmospheric pressure and temperature at the surface of Venus are 92 bars and 450°C respectively which make operation of electronic devices and sensors very difficult. Conventional cooling methods are currently deemed unfeasible due to the short life span of moving parts of the refrigerator systems at high temperatures. Furthermore, alternate energy sources such as solar power is not an option on Venus, since the cloud layer consisting of concentrated sulfuric acid droplets is thick and the surface reduces the solar intensity at the surface to about 2% of the intensity above the atmosphere. Therefore developing alternate method of power and cooling system is essential for Venus operation of any robotic rover. The advantages of using thermoacoustic systems are that there are no moving parts and they have efficiency comparable to conventional systems. Additionally there is a dearth in literature at using thermoacoustic refrigeration at high temperatures. This work discusses the development and optimization of a standing wave thermoacoustic engine refrigerator system to be used as a cooling device for the electronic components. The effects of various parameters such as gas mixture ratio, pressure, stack material etc. are discussed. The system designed provides cooling from 443K to 323K providing 150W of cooling.
