NASA is one step closer to finding life on Mars by discovering impact glass on the surface of the plant.
Mars impact craters have been found to contain deposits of glass by MRO, NASA’s Mars Reconnaissance Orbiter. These deposits have most likely been created by an asteroid impacting with the planet.
From samples taken of the glass scientist Peter Schultz discovered bits of ancient flora preserved inside from millions of years ago and if life was ever present on the Mars when the asteroid hit the planet, then they may have also preserved in the glass.
Alien life, such as microorganisms, has been hypothesized to exist in the Solar System and throughout the universe. This hypothesis relies on the vast size and consistent physical laws of the observable universe. According to this argument, made by scientists such as Carl Sagan and Stephen Hawking, it would be improbable for life not to exist somewhere other than Earth. This argument is embodied in the Copernican principle, which states that Earth does not occupy a unique position in the Universe, and the mediocrity principle, which suggests that there is nothing special about life on Earth.
Research shows us that glass is important for preserving biosignatures and with that knowledge Peter and others started looking for it and finally detected it on the surface.
There was already interest in Mars because of its crust which is thought to date back to when Mars was much wetter. What seems to be ancient hydrothermal fractures – vents that could have provided energy for life to exist – are also present on the planet.
Knowing that some of it might be preserved in a glassy component makes it very compelling to go search and possibly return with a sample.
