Seasons on Mars tend to last longer because the planet’s oval-shaped orbit around the sun means that a single Martian year is 687 days, or nearly two Earth years. Meanwhile, at Gale Crater in the Southern Hemisphere near the Martian equator, the Curiosity rover, which landed on Mars in 2012, has been experiencing highs of 5 F (minus 15 C) and lows of minus 105 F (minus 76 C). Perseverance rover is about to build a first-of-its-kind depot on MarsĪt the end of winter, the season’s buildup of ice can thaw and turn into gas, creating unique shapes that have reminded NASA scientists of Swiss cheese, Dalmatian spots, fried eggs, spiders and other unusual formations.ĭuring winter in Jezero Crater, recent high temperatures have been about 8 F (minus 13 C), while lows been about minus 120 F (minus 84 C). The rover's planned route is in black, with black dots representing notional waypoints for science or sampling along the way, while the ground it already covered is in white. This map shows the planned route NASA's Perseverance Mars rover will take across the top of Jezero Crater's delta in 2023. “Thanks to the Mars Climate Sounder, we can tell these snowflakes would be smaller than the width of a human hair.” Gallery of photos selected by public vote and featured as Image of the Week. “Because carbon dioxide ice has a symmetry of four, we know dry-ice snowflakes would be cube-shaped,” Piqueux said.

Beneath a microscope, Martian snowflakes would likely look a little different. The rock is about an inch across (2.5 centimeters). Thanks to photographers, we know snowflakes on Earth are unique and six-sided. NASA’s Curiosity Mars rover took this close-up view of a rock nicknamed Terra Firme that looks like the open pages of a book on April 15, 2023, the 3,800th Martian day, or sol, of the mission using the Mars Hand Lens Imager (MAHLI) on the end of its robotic arm. The Phoenix lander, which arrived on Mars in 2008, also used one of its laser instruments to detect water-ice snow from its spot about 1,000 miles (1,609 kilometers) away from the Martian north pole. It has made detections of carbon dioxide snow falling at the Martian poles. However, the Mars Climate Sounder instrument on the Mars Reconnaissance Orbiter can detect light that’s invisible to the human eye. INTERACTIVE: Mars and other places to search for life in the solar system The cameras on the orbiters can’t peer through the clouds, and no robotic explorers have been developed that could survive the freezing temperatures at the poles. So far, no orbiters or rovers have been able to see snow fall on the red planet because the weather phenomenon only occurs at the poles beneath cloud cover at night.

Groundbreaking Mars mission comes to an end NASA's InSight Mars lander took this final selfie on April 24, 2022, the 1,211th Martian day, or sol, of the mission.
