Several countries, including India and the United States, are collaborating on a Mars expedition to investigate the Red Planet’s habitability and look for signs of existence.
The National Aeronautics and Space Administration (NASA) successfully landed its Perseverance rover in the Jezero Crater earlier this month, which has been identified as an ancient lakebed that emerged billions of years ago.
The crater was filled with water to create a deep lake, which dried up as the planet’s atmosphere changed, according to Nasa’s Mars exploration program.
The Perseverance rover will investigate the ancient lake bed’s rocks and return samples in upcoming flights. Humans want to know if life once flourished on Mars, despite the fact that it is too cold and dry for life to survive there today.
How does Mars compare with Earth?
The Earth’s atmosphere is mainly nitrogen and oxygen, while the Martian atmosphere is mostly carbon dioxide. Earth has only one moon, which is a celestial satellite that revolves around the sun, while Mars has two small moons, Phobos and Deimos.
