The new analysis of the Martian meteorite challenges current thinking about how the planets of the Earth acquire elements, including basic life-forms, in the early stages of their formation.

Researchers are analyzing the Chassigny meteorite, which fell on Earth in 1815 and is thought to have been a sample from the depths of Mars and thus provided a window into the solar system’s early days.

The primary hypothesis of the formation of rocky planets such as the Earth is that they first received fluids – such as water and nutrients that evaporate at low temperatures – from the solar nebula, the rotating disk of matter around the Sun. The storms melted into the tropical ocean of tiny planets but later disappeared into space. Another variation was introduced later when chondritic meteorites – ancient asteroids, dust mites, and grains in the original solar system – crashed into planets, according to the theory.

But new research suggests that the development of Mars may have been different.

Sandrine Péron, a postdoctoral associate at ETH Zürich in Switzerland, and Sujoy Mukhopadhyay, a professor at the University of California, Davis, made conservative estimates of a small number of krypton isotopes, a refined gas, in meteorite samples at. UC Davis Noble Gas Laboratory. They were able to find the origin of the elements in the rock.

The two found krypton isotope measurements showed variability from chondritic sources instead of those associated with solar nebula. These findings suggest that meteorite volatiles were placed in the Red Planet’s crater much earlier than scientists previously thought, while the nebula still exists.

Significantly, Mars is thought to be much more relaxed than Earth, taking about four million years of solidarity, compared to 50 to 100 million years on our planet. This means that Red Planet provides a previous understanding of the solar system’s evolution history.

The observations “contradict the general belief that, during planetary formation, the chondritic evolving delivery occurs after the discovery of solar gas,” while also questioning the composition of the planet’s atmosphere. The researchers wrote in a study describing the new work.
