They decline deep in the troposphere with the rate of 3 m/s per km. [3] The winds near the surface of Venus are much slower than that on Earth. They actually move at only a few kilometres per hour (generally less than 2 m/s and with an average of 0.3 to 1.0 m/s), but due to the high density of the atmosphere at the surface, this is still enough ...
The highest point on Venus, Maxwell Montes, is therefore the coolest point on Venus, with a temperature of about 655 K (380 °C; 715 °F) and an atmospheric pressure of about 4.5 MPa (45 bar). [ 131 ] [ 132 ] In 1995, the Magellan spacecraft imaged a highly reflective substance at the tops of the highest mountain peaks, a " Venus snow " that ...
This requires Venus's temperature to be reduced, first to the liquefaction point, requiring a temperature less than 304.128(15) K [32] (30.978(15) °C or 87.761(27) °F) and partial pressures of CO 2 to bring the atmospheric pressure down to 73.773(30) bar [32] (carbon dioxide's critical point); and from there reducing the temperature below 216 ...
Given the different Sun incidence in different positions in the orbit, it is necessary to define a standard point of the orbit of the planet, to define the planet position in the orbit at each moment of the year w.r.t such point; this point is called with several names: vernal equinox, spring equinox, March equinox, all equivalent, and named considering northern hemisphere seasons.
Lowest temperature in the Northern Hemisphere: −69.6 °C (−93.3 °F); Greenland Ice Sheet, Greenland on 22 December 1991. [ 197 ] Coldest average monthly temperature in the Northern Hemisphere : −54.1 °C (−65.4 °F); Oymyakon , Russia for the month of January 1931.
Today's Venus is hellish, but NASA scientists have discovered that there was once a time where it could have been inhabitable.
The aircraft would carry the mission's sensitive electronics in the relatively mild temperatures of Venus' upper atmosphere. [79] Another concept from 2007 suggests to equip a rover with a Stirling cooler powered by a nuclear power source to keep an electronics package at an operational temperature of about 200 °C (392 °F).
