When asteroids and related outer-space objects crashed into Mars eons ago, they sent pieces of Mars’ core into space. These drifting rock pieces occasionally enter Earth’s atmosphere, where gravitational pull draws them inward (Siegel, 2018). Meteorites fall to Earth worldwide, but they are easier to locate in scorching or freezing deserts, in which the absence of flora and other minerals makes them unique. Since Martian meteorites are pricey, scientists often attempt to determine if they originated from Mars. One method is for scientists to study the gas chambers inside the ores of meteorites and contrast them to the surface of Mars. The images and videos used for comparison were retrieved from NASA’s 1976 Viking rovers (Siegel, 2018). Scientists may deduce that the rocks originated from Mars if the elements are the same.
Secondly, modern technology makes it simpler to determine the origin of nearly all objects in the universe, including meteorites. To determine whether the meteorite is from Earth or the cosmic beyond, scientists use the periodic table to compare the rocks’ chemical and physical makeup (Siegel, 2018). After completing this phase, scientists can further explore if the rocks have many qualities in common with the other previously discovered elements. The work of pioneering space scientists has enabled these achievements. For example, they used space explorers like the Vikings landers to record photographs and films for future generations to study. According to the information available, it is possible that other planets in the solar system, many of which may have formerly supported life, contain a variety of trapped gases or oxygen isotopes (Siegel, 2018). The properties of these elements can tell scientists whether they came from mars or elsewhere.
