An illustration depicts the possible extent of an ancient lake inside Gale Crater, where the rover landed in August 2012. The $2.5 billion NASA mission set out to explore Gale Crater, which was thought to have once hosted flowing water. Curiosity found evidence of clay formations, or \"mudstone,\" in the crater's Yellowknife Bay, scientists said in 2013. This clay may have held the key ingredients for life billions of years ago. It means a lake must have existed in the area. <\/p>\n

The Curiosity rover took this image of a rock formation informally dubbed \"Darwin.\" Scientists had the rover stop in this region, called Waypoint 1, because it appeared to be a prime area to study the inner makeup and history of the floor of the Gale Crater. Analysis of Darwin may provide evidence of whether water played a role in the layering of rocks in this region. <\/p>\n

Mars once had conditions favorable for microbial life, NASA scientists announced on March 12, 2013. One piece of evidence for that conclusion comes from this area of the Martian surface, nicknamed \"Sheepbed.\" It shows veins of sediments that scientist believe were deposited under water and was an environment once hospitable to life. <\/p>\n
Mars rover Curiosity <\/p>\n
The rock on the left, called Wopmay, was discovered by the rover Opportunity, which arrived in 2004 on a different part of Mars. Iron-bearing sulfates indicate that this rock was once in acidic waters. On the right are rocks from Yellowknife Bay, where rover Curiosity was situated. These rocks are suggestive of water with a neutral pH, which is hospitable to life formation. <\/p>\n

The robotic arm on NASA's Mars rover Curiosity delivered a sample of Martian soil to the rover's observation tray for the first time on October 16, 2012. <\/p>\n
Mars rover Curiosity <\/p>\n
This image shows part of the small pit or bite created when NASA's Mars rover Curiosity collected its second scoop of Martian soil on October 15, 2012. The rover team determined that the bright particle near the center of the image was native to Mars, and not debris from the rover's landing. <\/p>\n
Mars rover Curiosity <\/p>\n
This image shows what the rover team has determined to be a piece of debris from the spacecraft, possibly shed during the landing. <\/p>\n
Mars rover Curiosity <\/p>\n
The rover's scoop contains larger soil particles that were too big to filter through a sample-processing sieve. After a full-scoop sample had been vibrated over the sieve, this portion was returned to the scoop for inspection by the rover's mast camera. <\/p>\n
Mars rover Curiosity <\/p>\n
This 360-degree panorama shows the area where the rover will spend about three weeks collecting scoopfuls of soil for examination. The photo comprises images taken from the rover's navigation camera on October 5, 2012. <\/p>\n

NASA's Curiosity rover found evidence for what scientists believe was an ancient, flowing stream on Mars at a few sites, including the rock outcrop pictured here. The key evidence for the ancient stream comes from the size and rounded shape of the gravel in and around the bedrock, according to the Jet Propulsion Laboratory\/Caltech science team. The rounded shape leads the science team to conclude they were transported by a vigorous flow of water. The grains are too large to have been moved by wind. <\/p>\n
Mars rover Curiosity <\/p>\n
This photo is an up-close look at an outcrop that also shows evidence of flowing water, according to the JPL\/Caltech science team. The outcrop's characteristics are consistent with rock that was formed by the deposition of water and is composed of many smaller rounded rocks cemented together. Water transport is the only process capable of producing the rounded shape of conglomerate rock of this size. <\/p>\n
Mars rover Curiosity <\/p>\n
Curiosity completed its longest drive to date on September 26, 2012. The rover moved about 160 feet east toward the area known as \"Glenelg.\" As of that day the rover had moved about a quarter-mile from its landing site. <\/p>\n
Mars rover Curiosity <\/p>\n
This image shows the robotic arm of NASA's Mars rover Curiosity with the first rock touched by an instrument on the arm. The photo was taken by the rover's right navigation camera. <\/p>\n
Mars rover Curiosity <\/p>\n
This image combines photographs taken by the rover's Mars Hand Lens Imager at three distances from the first Martian rock that NASA's Curiosity rover touched with its arm. The images reveal that the target rock has a relatively smooth, gray surface with some glinty facets reflecting sunlight and reddish dust collecting in recesses in the rock. <\/p>\n
Mars rover Curiosity <\/p>\n
This rock will be the first target for Curiosity's contact instruments. Located on a turret at the end of the rover's arm, the contact instruments include the Alpha Particle X-Ray Spectrometer for reading a target's elemental composition and the Mars Hand Lens Imager for close-up imaging. <\/p>\n
Mars rover Curiosity <\/p>\n
Researchers used the Curiosity rover's mast camera to take a photo of the Alpha Particle X-Ray Spectrometer. The image was used to see whether it had been caked in dust during the landing. <\/p>\n
Mars rover Curiosity <\/p>\n
Researchers also used the mast camera to examine the Mars Hand Lens Imager on the rover to inspect its dust cover and check that its LED lights were functional. In this image, taken on September 7, 2012, the imager is in the center of the screen with its LED on. The main purpose of Curiosity's imager camera is to acquire close-up, high-resolution views of rocks and soil from the Martian surface. <\/p>\n
Mars rover Curiosity <\/p>\n
This is the open inlet where powdered rock and soil samples will be funneled down for analysis. The image is made up of eight photos taken on September 11, 2012, by the imager and is used to check that the instrument is operating correctly. <\/p>\n
Mars rover Curiosity <\/p>\n
This is the calibration target for the imager. This image, taken on September 9, 2012, shows that the surface of the calibration target is covered with a layor of dust as a result of the landing. The calibration target includes color references, a metric bar graphic, a penny for scale comparison, and a stair-step pattern for depth calibration. <\/p>\n
