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.

Sulfur Crystals on Mars: Curiosity’s Happy Accident and Other Surprises (Live Public Talk)

Scientists were stunned when a wheel on the Curiosity Mars rover recently cracked open a rock to reveal something never seen before on the Red Planet: yellow sulfur crystals. Dr. Ashwin Vasavada, Curiosity’s project scientist, explains the significance of the finding as well as other notable discoveries from the mountain-climbing Mars explorer’s 12th year on the Red Planet.

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.
