1. Mars refers to the planet Mars. As the fourth planet from the Sun in the Solar System, Mars is one of the terrestrial planets and has a diameter approximately 53% that of Earth and a mass around 14% of Earth's. It shares a similar axial tilt and rotation period with ...

Mars also has a seasonal cycle that is similar to that of Earth’s. This is due in part to the fact that Mars also has a tilted axis, which is inclined 25.19° to its orbital plane (compared to Earth’s axial tilt of approx. 23.44°). It’s also due to Mars orbital eccentricity,...
Mars is sensitive to changes in factors such as the tilt of its rotational axis as it orbits the Sun; it is thought that the stability of water at the surface has varied over thousands to millions of years as the axial tilt of the planet and its distance from the Sun undergo cyclical c...
Earth’s axial tilt (or obliquity) and its relation to the rotation axis and plane of orbit. Credit: Wikipedia Commons Mars’s axial tilt is very similar to Earth’s, being inclined 25.19° to its orbital plane (whereas Earth’s axial tilt is just over 23°). This means that Mars also...
Johann Heinrich M"adler and Wilhelm Beer were the first "areographers". They began by establishing that most of Mars’ surface features were permanent, and more precisely determining the planet's rotation period. In 1840, M"adler combined ten years of observations and drew the first map of ...
rotation is called asol. The planet's axis is tilted by 25.19° to its orbital plane. The rotation rate and axial tilt help to make the Red Planet the most earthlike of all the other planets, even though it has only 28% of the Earth's surface area and less than 38% of its ...

SESPA was proposed for Venus exploration at altitudes ranging from 71.5 to 75 Km concerning the long rotation period of Venus and the high value of its atmospheric density. In 2015, NASA Armstrong Engineering proposed designing and producing the prandtld-based fixed-wing prandtl-m, which will ...
