Planets in our solar system go through seasons because of the way they are tilted in their orbits, so one hemisphere faces the sun more than the other at certain times of the year. However, another factor affecting the weather and conditions of some planets is their location in their orbits around the Sun, which is a completely different matter. not important. But Mars’ orbit is more elliptical than Earth’s, which means conditions vary depending on when the planet approaches the sun. This effect is evident in two images of Mars recently released by NASA, which show the planet at its closest and farthest point from the sun. Taken six months in July 2022 and January 2023, respectively, these images, taken by the Mars rover and Mars Atmosphere EvolutioN, digitallands report, show how the planet’s environment changes with seasons and seasons. The planet’s orbit is changing. This first image was taken during summer in the planet’s southern hemisphere, when Mars was at its closest point to the sun. This image was taken using an ultraviolet spectrophotometer (IUVS) that operates in the ultraviolet wavelength. To create an image, the tool values must be converted to the visible light range. This helps identify key features in the image, such as the purple appearance of atmospheric ozone, which is why the planet’s surface appears green in some places, even though the actual planet appears red or orange when photographed at visible wavelengths. At the bottom of the planet, you can see the Antarctic ice cap, which has shrunk in the relatively warm summer weather. This second image, which shows Mars’ northern hemisphere, was taken when the planet was at its farthest from the sun. You can see the bright purple ozone cap across the North Pole. This ozone is formed during the winter months when sunlight breaks down carbon dioxide in the atmosphere, and when spring arrives, the ozone reacts with water vapor and is lost. MAVEN is used to study Mars’ atmosphere and climate, and has already investigated how the polar ice absorbs water vapor during the summer and how it is affected by the large dust storms that periodically sweep across the planet.
