The Martian Meteorite - The Most Important discovery in Earth Science of the Last Century!
Introduction: What is a Martian meteorite?
A martian meteorite is a meteorite that originates from Mars. It is a rock that has been blasted off of the surface of Mars by an impact event and then traveled through space until it landed on Earth. There are two types of martian meteorites: shergottites, which are volcanic in nature, and nakhlites, which are igneous in nature.
We can find more information about these rocks by examining them under an electron microscope. An electron microscope uses electrons to create images on a screen so we can see the atomic structure of the sample. We can also use X-rays to examine these rocks for chemical composition and mineralogy.
What are the different types of Martian meteorites?
Meteorites are rocks that have fallen from space and landed on Earth. There are two types of meteorites: stony and iron meteorites. A Martian meteorite is a type of stony meteorite that has originated from Mars.
Martian rocks are different from the other types of meteorites because they contain minerals that only form in the presence of water, such as clays, kaolinite, and serpentine. These minerals were formed by volcanic activity and hydrothermal vents on the surface of Mars. We know these rocks came from Mars because they match the chemical composition found in Martian soil samples collected by NASA's Viking mission in 1976.
How do we identify Martian meteorites?
Martian meteorites are rocks that come from Mars and end up on Earth. They are rare to find, but scientists have found many of them. In order to identify a martian meteorite, you need to know what they look like. Martian meteorites are black or dark brown in color and are usually pitted with small holes. They also have a high iron content, which is different from other types of rocks on Earth.
The first step in identifying a martian rock is to make sure it is not just an ordinary rock from Earth by looking for the following features:
- it's black or dark brown in color
- it has small holes
- it has an iron content that's higher than any other type of rock on Earth
How was NW Africa 7285 found and identified as a Martian meteorite?
The first meteorite found on Earth that was identified as coming from Mars was the Tissint meteorite. It was found in Morocco in July 2011 and identified by a team of scientists led by Dr. Caroline Smith, curator of meteorites at London's Natural History Museum.
In September 2012, NASA’s Curiosity rover discovered a martian meteorite on earth – the first rock from Mars ever seen on Earth. The rover had been exploring the foothills of Mount Sharp when it uncovered the 0.4-ounce (12 grams) rock that would be named Northwest Africa 7285, or “NWA 7285” for short.
NASA scientists say there are about 8,000 pounds (3,600 kilograms) of martian rocks in earth's orbit that could eventually

Overview - What are Meteorites?
Meteorites are rocks from space that have fallen to Earth. They are mostly made of iron and nickel and can range in size from a few inches to hundreds of feet across.
Meteorites are rocks that come from outer space and fall onto the Earth's surface. These meteorites are mainly made up of iron and nickel, with some containing traces of other materials such as silicon, oxygen, magnesium, calcium, or sulfur. Meteorites typically range in size from a few inches to hundreds of feet across.
