Perseverance

Part of NASA's Mars Science Laboratory mission, at the time of launch Curiosity was the largest and most capable rover ever sent to Mars. Part of NASA's Mars Science Laboratory mission, Curiosity, was the largest and most capable rover ever sent to Mars when it launched in 2011. Curiosity set out to answer the question: Did Mars ever have the right environmental conditions to support small life forms called microbes? Early in its mission, Curiosity's scientific tools found chemical and mineral evidence of past habitable environments on Mars. It continues to explore the rock record from a time when Mars could have been home to microbial life. This graphic shows the long-chain organic molecules decane, undecane, and dodecane. These are the largest organic molecules discovered on Mars to date. They were detected in a drilled rock sample called “Cumberland” that was analyzed by the Sample Analysis at Mars lab inside the belly of NASA’s Curiosity rover. The rover, whose selfie is on the right side of the image, has been exploring Gale Crater since 2012. An image of the Cumberland drill hole is faintly visible in the background of the molecule chains. NASA's Curiosity Mars rover has collected 42 powderized rock samples with the drill on the end of its robotic arm. This grid shows all 42 holes made by the drill when collecting the samples. The Curiosity rover has taught us a lot about the history of Mars and its potential to support life. Take a tour of its landing site, Gale Crater.

NASA’s Curiosity Mars rover used LED lights on the end of its robotic arm to create this rare nighttime view of the Red Planet’s surface on Dec. 6, 2025, the 4,740th Martian day, or sol, of the rover’s mission. The LED lights are part of the Mars Hand Lens Imager, or MAHLI, a camera on the end of Curiosity’s robotic arm. The image was captured by the Mast Camera, or Mastcam, on the rover’s mast, or “head.” Credits: NASA/JPL-Caltech/MSSS NASA’s Mars Perseverance rover seeks signs of ancient life and collects samples of rock and regolith for possible Earth return.
