But just a few years after the Phoenix lander discoveries, the Mars Reconnaissance Orbiter revealed carbon dioxide snowfall at the southern polar region in — the first ever observation of this phenomenon in the Solar System.
More recently, surveys of the soil and the atmosphere have revealed a few more hidden mysteries. They were conducted by a number of orbiters and landers including the Mars Science Laboratory, the Mars Orbiter Mission, the Mars Atmosphere and Volatile Evolution probe along with the two currently active rovers, Opportunity and Curiosity.
Scientists have demonstrated that around 3. Mars has 'dust devils' purging over its surface. Solar heat creates convection currents which drive the winds on Mars. Due to the dry and dusty conditions, freshly deposited dust can be pulled several miles high. Mars often experiences dust storms on its surface too. Back in when the Mariner 9 orbiter arrived at Mars it was greeted by the Martian world covered in a haze.
This global dust storm lasted for a month — only after it died down did the orbiter manage to send back images of the Martian surface below. The Hubble Space telescope also spotted a dust storm on Mars in which appeared to die down before coming back with a vengeance to become the largest dust storm recorded on Mars in 25 years. The huge amount of dust drawn up into the atmosphere caused the atmospheric temperature to increase by 30 degrees C — a global warming effect.

Mars has four seasons , roughly twice as long as those on Earth, but with more variation given Mars' eccentric orbit and the fact its orbital speed varies more as result fastest when at perihelion ; slowest at aphelion.

MarCOs, Mars and Earth. This image is a cropped version of the last degree panorama taken by the Opportunity rover's Panoramic Camera Pancam from May 13 through June 10, The view is presented in false color to Opportunity Legacy Pan.
An image of InSight's robotic arm, with its scoop and stowed grapple, poised above the Martian soil. The image was received on Dec. In this artist's concept of NASA's InSight lander on Mars, layers of the planet's subsurface can be seen below and dust devils can be seen in the background. A Cutaway of InSight on Mars. Infographic text: Viking. Tianwen-1 is carrying three different probes: an orbiter, lander and small rover. Then on Feb. So, it's going to be a busy year on the Red Planet.

Mars has four seasons just like we do on Earth, with cooler winters and warmer summers. The Martian year always begins with the northern hemisphere's spring equinox, which begins autumn in the southern hemisphere.
