Section 1: Reading Comprehension

The Curiosity Rover: A Robotic Explorer

In August 2012, a car-sized robotic rover named Curiosity landed on Mars after a harrowing journey through space. Curiosity was sent by NASA to explore Gale Crater, a massive impact site with a large mountain in the center. The rover’s primary mission was not to look for Martians, but to determine if Mars ever had the right environmental conditions to support small life forms called microbes. To do this, Curiosity carries advanced tools like lasers to zap rocks and a drill to collect powder from the planet’s surface.

Since its landing, Curiosity has made several groundbreaking discoveries. It found evidence of ancient streambeds, suggesting that liquid water once flowed across the Martian surface. The rover also detected organic molecules, which are the building blocks of life. Despite the harsh radiation and freezing temperatures, Curiosity continues to climb Mount Sharp, sending high-definition photos back to Earth. Each photo helps scientists understand the history of the Red Planet and prepares humanity for the possibility of sending astronauts there in the future.
