Curiosity Rover's 4,000-Day Journey on Mars

NASA's Curiosity rover has reached a historic milestone of 4,000 days on Mars, continuing to explore the planet's ancient climate. Despite challenges like a jammed camera filter wheel, the rover recently drilled its 39th sample from the sulfate-rich "Sequoia" region. The samples collected will provide insights into Mars' past habitability and how its climate evolved over time. Engineers are working to resolve the camera issue, and the rover's nuclear power source is expected to provide enough energy for many more years of operation. The team is preparing for a break in November when Mars will be behind the Sun, and communications may be affected.
