The first known meteorite discovered on Mars (and the third known meteorite found someplace other than Earth) was Heat Shield Rock. The first and the second ones were found on the Moon by the Apollo missions. [13] [14] On October 19, 2014, Comet Siding Spring passed extremely close to Mars, so close that the coma may have enveloped the planet.
NASA's Mars Reconnaissance Orbiter, which has been studying Martian terrain since it was launched 12 years ago, recently discovered a feature on the Red Planet's surface that has left researchers ...
Since landing on Mars on August 5, 2012, the Curiosity rover has ascended 2,600 feet (800 meters) up the base of Mount Sharp from the floor of Gale Crater. The mountain is a central peak of the ...
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.
The system spotted the craters by scanning photos by NASA’s Mars Reconnaissance Orbiter, which was launched in 2005 to study the history of water on the red planet. NASA releases images of the ...

Scientists have announced the discovery of structures like layering and potential impact craters which had been hidden under Mars’ polar ice caps. New 3-D map of Mars' ice caps reveal hidden ...
More recently, in 2024, two studies found evidence for a companion star. One study found that a not yet directly-observed, dust-modulating star or white dwarf of 1.17 ± 0.07 M ☉ at a distance of 8.60 ± 0.33 AU would be the most likely solution for Betelgeuse's 2170-day secondary periodicity, fluctuating radial velocity, moderate radius and ...
