In 2012, scientists analyzed the discovery of a meteorite in the Sahara Desert. The meteorite came from Mars and is called NWA 7533. Scientists are studying the meteorite, its structure, and what Mars looked like 4.4 billion years ago.
Meteorite The composition of the minerals is revealed by the chemical signatures of oxidation. The meteorite is very small, weighing 84 grams, and part of its name is found in northwest Africa. It is the remains of a large meteorite that decomposes when it enters the Earth’s atmosphere.
Researchers are now able to validate previous theories that Mars was water at least 3.7 billion years old, from a meteorite 4.4 billion years old. The meteorite shows that water was on the Red Planet 700,000 years ago.
With the indications that water existed on Mars much earlier than previously believed, water was a natural by-product of certain processes from the very beginning of the formation of the planets. Scientists hope this finding will help answer the question of exactly where water comes from. NWA 7533 is the oldest existing meteorite on Mars.
The researchers provided meteorite samples to a quartet of different spectroscopic analyzes. Each of them is a method of chemical fingerprint detection, and there is strong evidence for the oxidation of magma. Oxidation could have occurred if the crust of Mars had been hydrated 4.4 billion years ago when part of that crust melted. The analysis also suggests that the impact of the meteorite, which caused the planets to heat up, would emit significant amounts of hydrogen during a time when Mars already had a very dense atmosphere. The atmosphere of that Mars is now lost.
