Touchdown! Robot lands safely on Mars
Is there life on Mars? Last week, NASA rover Perseverance touched down on the nearby planet after a journey of over seven months. While on Mars, it will be searching for clues of life.
“Touchdown confirmed”, the controller said.
The room of people at NASA’s mission control jumped up and began cheering and clapping. Years of work, millions of dollars and a seven-month journey through space were worth it. Their rover had landed on Mars.

Perseverance arrived on Mars late last Thursday night. The team in charge was delighted. Landing on Mars is so difficult that experts call it the seven minutes of terror.
The rover is the fifth NASA has sent to Mars. It is also the biggest and most advanced. It is as large as a 4x4. There is a robotic arm for picking up pieces of rock to study. And it even has a separate drone called Ingenuity that can break away and fly around large areas.
Perseverance has already sent back some picture from the surface of the planet. Now, it will start moving towards the edge of a crater called Jezero to look for ancient water. Scientists hope this could be proof that there was once life on the planet.
So, is there life on Mars?
Probably not. Mars is a desert of red dust. It is colder than the Antarctic. The winds are fast and dangerous. The air is filled with CO2. There may have been life once. But that was before Mars lost its water and became so empty. It is unlikely to expect anything lives there naturally anymore.
Maybe! Just because Mars seems empty and harsh to us, some creatures might thrive. The Sahara desert is dry and dangerous, but creatures have evolved to survive. In the deep sea, animals live happily miles underwater without sunlight or heat. Life probably does exist on Mars. It just might not look much like us.
