Auroras occur on Mars, but they do not occur at the poles as on Earth, because Mars has no planetwide magnetic field. Rather, they occur near magnetic anomalies in Mars's crust, which are remnants from earlier days when Mars did have a magnetic field. Martian auroras are a distinct kind not seen elsewhere in the Solar System. [21]

Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
When Mariner 4 flew by Mars on July 15, 1965, it captured the first images of another planet from space. But the first image of Mars ever seen on TV was different than expected.
They have even blown the dust off the solar panels of the Spirit and Opportunity Rovers on Mars, greatly extending their lives. [6] The twin Rovers were designed to last for 3 months; instead, Spirit lasted for 6 years, 77 days, while Opportunity continued to operate for a staggering 14 years, 136 days.
In Mars orbit or deep space, the dose rate would be significantly more,” said Don Hassler, RAD principal investigator at the Southwest Research Institute’s Solar System Science and Exploration ...
The dark features were thought to be seas, hence their names Mare Erythraeum, Mare Sirenum and Aurorae Sinus. The largest dark feature seen from Earth is Syrtis Major Planum. The shield volcano, Olympus Mons (Mount Olympus), rises 22 km above the surrounding volcanic plains, and is the highest known mountain on any planet in the solar system. [10]
The following outline is provided as an overview of and topical guide to Mars: Mars – fourth planet from the Sun and the second-smallest planet in the Solar System, after Mercury. Named after the Roman god of war, it is often referred to as the "Red Planet" [1] [2] because the iron oxide prevalent on its surface gives it a reddish appearance.
