In 1902, Léon Teisserenc de Bort from France and Richard Assmann from Germany, in separate but coordinated publications and following years of observations, published the discovery of an isothermal layer at around 11–14 km (6.8-8.7 mi), which is the base of the lower stratosphere.
1 sty 2014 · The present tilt of Mars' axis (25.2°) is similar to that of the Earth (23.5°), and a Martian year is 687 Earth days long or about 1.9 Earth years. Consequently, seasonality bears some similarity to that of the Earth but Martian seasons last about twice as long on average.
The geological history of Mars follows the physical evolution of Mars as substantiated by observations, indirect and direct measurements, and various inference techniques.
21 gru 2020 · The Mars Global Surveyor spacecraft took the first photograph of the Earth-Moon system from its orbit around Mars, from a distance of 86 million miles. Because the Earth and Moon are closer to the Sun than Mars, they exhibit phases, much as Venus and Mercury do as viewed from Earth.
