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.
China's Zhurong Mars rover found strange geometric shapes ... it eventually shut down in May 2022 after a little more than an Earth year on Mars. In that time, the rover gathered invaluable data ...
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 ...
There appear to be huge reservoirs under Mars, scientists have said. Evidence suggests that there are vast lakes of liquid water under the surface of the red planet, according to a new study.
Theia or Orpheus, [21] a Mars-sized impactor believed to have collided with the Earth roughly 4.5 billion years ago; an event which created the Moon. Evidence from 2019 suggests that it may have originated in the outer Solar System. [22] Vulcan, a hypothetical planet once believed to exist inside the orbit of Mercury. Initially proposed as the ...
That Mars once possessed large amounts of water was confirmed by isotope studies in a study published in March 2015, by a team of scientists showing that the ice caps were highly enriched with deuterium, heavy hydrogen, by seven times as much as the Earth. This means that Mars has lost a volume of water 6.5 times what is stored in today's polar ...
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 ...
Due to Mars's tenuous atmosphere, with just 0.6% the surface pressure of Earth's, incoming meteors are much less prone to breaking up. [6] while a 10-meter (33 ft) asteroid falling over Earth is unlikely to reach the surface intact before being destroyed in a meteor air burst, [7] a 10-meter (33 ft) asteroid falling over Mars may leave a crater ...
