محاكاة كوكب المريخ - صورة أرشيفية تصوير : وكالات

كشفت صور جديدة لسطح كوكب المريخ التقطتها وكالة الفضاء الأوروبية ونظيرتها الروسية الكوكب المشهور بالكوكب الأحمر على نحو لم يره العالم من قبل، حيث بدا مثل حلوى «الكوكيز والكريمة» وليس باللون الأحمر المعتاد.

وبدت على الجانب الأيمن من الصور كثبان على شكل أهلة، وبات بوسع العلماء من خلال مشاهدة الصورة القول بأن رياحا ثانوية كانت وراء تشكيل هذه الكثبان.
كما التقطت وكالة الفضاء الأمريكية (ناسا) صورا تكشف عن صخور ورمال تجمدت معا بفعل الزمن وقاومت بعضها التآكل بفعل الزمن بينما بدت مظاهر التآكل على البعض الآخر.

A recent photo taken by the Curiosity rover shows its current location, known as "Teal Ridge." The rover has been studying the clay-bearing unit in this region.

Cooled lava helped preserve a footprint of where dunes once moved across a southeastern region on Mars. But it also looks like the "Star Trek" symbol.

InSight's seismometer recorded a "marsquake" for the first time on April 6, 2019.

A photo of a preserved river channel on Mars, taken by an orbiting satellite, with color overlaid to show different elevations. Blue is low and yellow is high.

NASA has been exploring Mars since 1965. Here are some of the best moments captured by Mars missions over the years. <br />The European Space Agency's Mars Express mission captured this image of the Korolev crater, more than 50 miles across and filled with water ice, near the north pole.

What are blueberries doing on Mars? These small, mineral hematite-rich concretions are near Fram Crater, visited by NASA's Opportunity rover in April 2004. The area shown is 1.2 inches across. The view comes from the microscopic imager on Opportunity's robotic arm, with color information added from the rover's panoramic camera. These minerals suggests that Mars had a watery past.

Mars is far from a flat, barren landscape. Nili Patera is a region on Mars in which dunes and ripples are moving rapidly. HiRISE, onboard the Mars Reconnaissance Orbiter, continues to monitor this area every couple of months to see changes over seasonal and annual time scales.

HiRISE captured layered deposits and a bright ice cap at the Martian north pole.

Although Mars isn't geologically active like Earth, surface features have been heavily shaped by wind. Wind-carved features such as these, called yardangs, are common on the Red Planet. On the sand, the wind forms ripples and small dunes. In Mars' thin atmosphere, light is not scattered much, so the shadows cast by the yardangs are sharp and dark.
