The meteoroid resurfaced in a drawer in the biology department at Purdue University. After wandering through space for a few million years He came to earth.

By examining this meteorite that fell on our planet, Learn more about Mars We could have it.

The Lafayette meteorite was blown into space 11 million years ago.

The rock that broke off the surface and was thrown into space after millions of years by an asteroid that hit Mars By the gravity of our planet It fell in the US state of Indiana. Later this meteorite was forgotten.

The Lafayette meteorite was discovered years later in a drawer in the biology department at Purdue University. Researchers at the university isotopic dating method (a method used to determine the age of objects containing organic material) confirmed that the source of the chemical changes in the meteorite was liquid water.

But this still doesn’t mean that Mars had large bodies of water like oceans at the time. Researchers say this is water formed by melting ice beneath the surface in your opinion.

Professor Marissa Tremblay says:

“We don’t think there was much liquid water on the surface of Mars at that time. Instead of water, permafrost “We think this is due to the melting of the subsurface ice in the area, called ice, and that this melting of the permafrost is caused by the magmatic activity that still occurs periodically on Mars to this day.”

It is unclear when contact with the liquid on Mars occurred.

Research conducted at the Field Museum in Chicago in the 1980s found that the meteorite contained gases specific to the Martian atmosphere, but when contact with liquid water on Mars occurred remained a mystery. Recent research shows that this interaction It took place 742 million years ago It shows.
