In addition, Mars’s orbit is less circular than Earth’s, which means that its orbital velocity varies more over the course of a Martian year. This annual variation affects the timing of the red planet’s solstices and equinoxes. On Mars, the northern hemisphere’s spring and summer are longer than the fall and winter.

The agency’s latest and most complex mission to the Red Planet has touched down at Jezero Crater. Now it’s time to begin testing the health of the rover. Elon Musk once branded Jeff Bezos a 'dilettante' of space exploration, but the Blue Origin founder is poised to beat SpaceX to Mars

The rover’s technologies for entry, descent, and landing also will provide information to advance future human missions to Mars.

Scientists think the Valles Marineris formed mostly by rifting of the crust as it got stretched. Individual canyons within the system are as much as 60 miles (100 km) wide. The canyons merge in the central part of the Valles Marineris in a region as much as 370 miles (600 km) wide. Large channels emerging from the ends of some canyons and layered sediments within suggest that the canyons might once have been filled with liquid water.

Some 28 miles (45 kilometers) wide, Jezero Crater sits on the western edge of Isidis Planitia, a giant impact basin just north of the Martian equator. Scientists have determined that 3.5 billion years ago the crater had its own river delta and was filled with water. Kim Kardashian's fans go wild over what she does with her tongue in pouty selfies to plug SKIMS: 'A bit X-rated Kimmy!'The Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft will continue to study the atmosphere, the immobile Curiosity of Perseverance rovers will continue to monitor the Martian surface, the Mars Reconnaissance and Odyssey orbiters will carry on as usual, and even NASA’s tiny helicopter Ingenuity will continue to monitor the movement of Martian sand while it is grounded.

Also future-leaning is the Ingenuity Mars Helicopter, which will remain attached to the belly of Perseverance for the flight to Mars and the first 60 or so days on the surface. A technology demonstrator, Ingenuity's goal is a pure flight test – it carries no science instruments. Kevin McCloud reveals husband who appears in upcoming series of Grand Designs died during the projectNASA’s Perseverance Mars rover used one of its navigation cameras to take a series of images of drifting clouds just before sunrise on March 18, 2023, the 738th Martian day, or sol, of the mission. Landing on Mars is always an incredibly difficult task and we are proud to continue building on our past success,” said JPL Director Michael Watkins. “But, while Perseverance advances that success, this rover is also blazing its own path and daring new challenges in the surface mission. We built the rover not just to land but to find and collect the best scientific samples for return to Earth, and its incredibly complex sampling system and autonomy not only enable that mission, they set the stage for future robotic and crewed missions.” Mars is 4,220 miles (6,791 km) in diameter —far smaller than Earth, which is 7,926 miles (12,756 km) wide. The Red Planet is about 10% as massive as our home world, with a gravitational pull 38% as strong. (A 100-pound person here on Earth would weigh just 38 pounds on Mars, but their mass would be the same on both planets.) Atmospheric composition (by volume)
