Where is Curiosity?

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.

Landing Site: Gale Crater

Curiosity explores Gale Crater and acquires rock, soil, and air samples for onboard analysis. The car-size rover is about as tall as a basketball player and uses a 7 foot-long arm to place tools close to rocks selected for study. Curiosity's large size allows it to carry an advanced kit of 10 science instruments. It has tools including 17 cameras, a laser to vaporize and study small pinpoint spots of rocks at a distance, and a drill to collect powdered rock samples. It hunts for special rocks that formed in water and/or have signs of organics.

Watch

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.

Mars 2020: Perseverance Rover

NASA’s Perseverance Mars rover took this selfie on July 23, 2024, the 1,218th Martian day, or sol, of the mission. To the left of the rover near the center of the image is the arrowhead-shaped rock nicknamed “Cheyava Falls,” which has features that may bear on the question of whether Mars was home to microscopic life in the distant past. The small dark hole in the rock is where Perseverance took a core sample, which is now in a sample tube stored in the rover’s belly. The white patch to the right of the hole is where the rover used an abrasion tool to clear away the top surface, allowing science instruments to study the rock’s composition.
