New findings regarding the connection between the increase of oxygen in the atmosphere and the development of complex life

  • No comments
Hebrew University researchers have revealed new findings regarding the connection between the increase in oxygen in the atmosphere and oceans on Earth, and the development of complex life. The study indicates that the rise of oxygen occurred after the development of complex life, contrary to previous assumptions

This is not a simulation. The Perseverance robotic all-terrain vehicle and the crane that lowered it photographed each other and the Martian soil in a way that made it possible to document the landing as if it were a landing on Earth. NASA: We wanted to share with the public a once in a lifetime experience * the landing certificate step by step
