The Martian Meteorite

The video discusses the exploration of Mars through robotic laboratories that collect and analyze samples, providing insights into the planet's geology. Due to high costs, returning samples to Earth was deemed impractical until similarities were found between Martian data and meteorites on Earth. A meteor collision with Mars 16 million years ago sent debris to Earth, leading to the discovery of a Martian meteorite in Antarctica. This meteorite, studied at the Johnson Space Centre, was identified as lava from a Martian volcano, offering a more feasible way to study Martian geology.
