Curiosity Project Scientist Ashwin Vasavada gives a descriptive tour of the Mars rover's view in Gale Crater. The scene from "Vera Rubin Ridge" looks back over the journey so far, including buttes, dunes and other features along the route.
Five years of images from the front left hazard avoidance camera (Hazcam) on NASA's Curiosity Mars rover were used to create this time-lapse movie. The inset map shows the rover's location in Mars' Gale Crater. Each image is labeled with the date it was taken, and its corresponding sol (Martian day), along with information about the rover's location at the time.
NASA's Mars Reconnaissance Orbiter has clocked more than a decade of service at the Red Planet and has yielded scientific discoveries and magnificent views of a distant world. These images taken by MRO's HiRISE camera are not in true color because they are optimized for geological science. (Audio: music only)
This animation is a shorter clip from the video "Curiosity and MAVEN Explore Mars." While Curiosity will not be able to see MAVEN as it arrives at Mars, the rover welcomes the orbiter's discoveries. (Audio: music and mechanical sounds only)
When the Martian Moon Phobos passed in front of the sun, from the perspective of NASA's Mars rover Curiosity, the rover recorded the eclipse in the sky as well as the shadow darkening the ground. (No audio)
This movie clip shows Phobos, the larger of the two moons of Mars, passing overhead, as observed by NASA's Mars rover Curiosity in a series of images centered straight overhead starting shortly after sunset. Phobos first appears near the lower center of the view and moves toward the top of the view. The clip runs at accelerated speed; the amount of time covered in it is about 27 minutes. The 86 frames combined into this clip were taken by the rover's Navigation Camera (Navcam) on the 317th Martian day of Curiosity's work on Mars (June 28, 2013, PDT). The apparent ring about halfway between the center of the frames and the edges is an artifact of the imaging due to scattering of light inside the camera. (No audio)
This sequence of images from the Front Hazard-Avoidance Camera on NASA's Mars rover Curiosity shows the rover drilling into rock target 'Cumberland.'

This animation shows how the Mars Hand Lens Imager (MAHLI) camera at the end of the arm of NASA's Mars rover Curiosity was positioned for taking multiple images that were later combined into a self-portrait of the rover. The animation was made using software that rover planners use to design Curiosity's movements. (No audio)
This video clip shows the first Martian material collected by the scoop on the robotic arm of NASA's Mars Curiosity rover, being vibrated inside the scoop after it was lifted from the ground on Oct. 7, 2012. The clip includes 256 frames from Curiosity's Mast Camera, taken at about eight frames per second, plus interpolated frames to run at actual speed in this 32-frames-per-second version. The scoop was vibrated to discard any overfill. Churning due to vibration also serves to show physical characteristics of the collected material, such as an absence of pebbles. The scoop is 1.8 inches (4.5 centimeters) wide, 2.8 inches (7 centimeters) long. (No audio)
NASA scientists and engineers prepare Mars Curiosity rover for its first scoop of soil for analysis.The rover's ability to put soil samples into analytical instruments is central to assessing whether its present location on Mars, called Gale Crater, ever offered environmental conditions favorable for microbial life.
This video, presented at four times actual speed, shows a test using an engineering model of the soil scoop for NASA's Mars rover Curiosity. The scoop dips to about 1.4 inches (3.5 centimeters) deep. This test took place at NASA's Jet Propulsion Laboratory, Pasadena, Calif., in 2011.
Curiosity's scoop will collect soil samples to be sieved, processed and delivered to analytical instruments inside the rover. (No audio)
This engineering animation depicts the moves that NASA's rover Curiosity made on Sept. 22, 2012, when the rover touched a Martian rock with its robotic arm for the first time. Curiosity examined the rock with instruments on the arm. This animation was made with the software that engineers used for planning the maneuver: Rover Sequencing and Visualization Program.
This simulation shows planned movements of the arm on NASA's Curiosity rover for round one of its robotic arm checkouts, expected to run on Sol 33 (Sept. 8, 2012). This so-called "teach point" checkout activity consists of repeating arm moves and taking images with the Mars Hand Lens Imager (MAHLI) to match those acquired on Earth prior to launch. This ensures that the calibration and placement accuracy of the arm is within expected levels on Mars, which has different environmental conditions, such as weaker gravity.
This engineering tool, called the Rover Sequencing and Visualization Program (RSVP) helps engineers plan the rover's motions and drives. The visualization component of the RSVP tool is called Hyperdrive. (No audio)

Members of NASA's Mars Science Laboratory mission listen to a voice message from NASA Administrator Charles Bolden in the mission support area at the Jet Propulsion Laboratory. The message, which had been sent to Mars and back, was played for the team on Aug. 27, 2012.
This animation shows how NASA's Curiosity rover communicates with Earth via two of NASA's Mars orbiters, Mars Reconnaissance Orbiter (MRO) and Odyssey, and the European Space Agency's Mars Express. The rover sends the signals to the orbiters, which then passes them on to Earth. This allows for more data to be transmitted at a faster rate.
The paths of the orbiters around Mars are shown, in addition to the location of Curiosity within Gale Crater. The movie then switches to the perspective of the rover, showing the route of MRO overhead.
Back on Earth, the signals are picked up by large antenna dishes at NASA's Deep Space Network (DSN), which has three complexes in Goldstone, Calif., Madrid, Spain and Canberra, Australia. The DSN sends the information to Curiosity's mission control at NASA's Jet Propulsion Laboratory, Calif. (No audio)
This movie from NASA's Curiosity rover shows most of the high-resolution frames acquired by the Mars Descent Imager between the jettison of the heat shield and touchdown. The video, obtained on Aug. 5 PDT (Aug. 6 EDT), covers the last two-and-a-half minutes before touchdown in Gale Crater.
Audio recorded from mission control can be heard, counting down the critical events.

This simulation shows the first test drive of NASA's Curiosity rover. This tool, called the Rover Sequencing and Visualization Program (RSVP) helps engineers plan the rover's drives, modeling pebbles and bumps in the terrain. The visualization component of the RSVP tool is called Hyperdrive.
The tool shows the sped-up plan for the drive; the actual drive took place at 7:17 a.m. PDT (10:17 a.m. EDT) on Aug. 22, 2012, and lasted about 16 minutes. The drive demonstrated that the wheel actuators, or motors, are working.
To start its forward drive, Curiosity's drove about 3 feet (90 centimeters), rotating its wheels 180 degrees, before stopping to take pictures of the wheels. It then continued forward another 12 feet (3.6 meters), totaling 15 feet (4.5 meters) of forward motion. The rover then rotated 120 degrees, stopping again during the turn to take more pictures. Finally, Curiosity rolled backward 8.2 feet (2.5 meters) and snapped more pictures from its final location. The total drive distance was nearly 23 feet (7 meters). Curiosity is now about 20 feet (6 meters) from its landing site, called Bradbury Landing, and more than 16 feet (5 meters) from the scour mark called Goulburn, which scientists are currently investigating.

This short video clip shows final testing of the mast unit of the Chemistry and Camera (ChemCam) instrument for NASA's Curiosity before it was installed on the rover. An iron pyrite crystal was used as a target, located about 2.5 meters (8 feet) from the instrument. The laser was fired, first at 3 Hertz (pulses per second) and then at 10 Hertz. The last spark was captured as a still image to better display the size and shape of the plasma, or ionized gas. The test, performed at Earth's atmospheric pressure, took place at Los Alamos National Laboratory in New Mexico, which assembled and tested the instrument. (No audio)
This video steps viewers through a portion of the choreography needed to land NASA's Curiosity rover on Mars.

It ends with a high-resolution color image from Curiosity's Mast Camera.
This animation depicts movements of the robotic arm of NASA's Mars rover Curiosity as commanded for Aug. 20, 2012, the first time the arm was used on Mars. The animation is derived from visualization software that rover planners use in developing the commands sent to the rover. (No audio)
This sequence of images shows the heat shield from NASA's Mars Science Laboratory hitting the ground on Mars and raising a cloud of dust. The images were taken by the Mars Descent Imager on the mission's Curiosity rover while the rover was still suspended on a parachute, after the spacecraft had jettisoned the heat shield.
A dark spot, the shadow of the heat shield, enters the scene from lower left, moving toward the center. The bright heat shield itself is also apparent just before the shadow and hardware meet in the impact on the surface. The area of ground visible in the images is about six-tenths of a mile (1 kilometer) across. The frames shown here are cropped portions of full-frame images from the Mars Descent Imager.
The sequence includes 25 frames, repeated in five run-throughs for this presentation. The action is full speed in the first, fourth and fifth run-throughs. It is one-half and one-eighth speeds in the second and third run-throughs. (No audio)

This animation shows the approximate true position of NASA's Curiosity rover on Mars. A 3-D virtual model of Curiosity is shown inside Gale Crater, near Mount Sharp, Curiosity's ultimate destination. Like any wise hiker heading out on a trip, Curiosity will do a self-check to make sure her tools are working before she makes her way to the foot of Mount Sharp. This animation is derived from a virtual rover experience where the public can be an explorer and follow in Curiosity's journey day by day. Using the Unity game engine plug-in, the public can see what Curiosity is up to and follow in her footsteps as she explores. (No audio)
This animation shows NASA's Mars Reconnaissance Orbiter flying over NASA's Curiosity (shown in pink) as the rover lands on the Red Planet. The video is slowed down as the orbiter approaches the landing site for better viewing. Mars Reconnaissance Orbiter will capture data during Curiosity's entry, descent and landing for later playback to Earth. Its High Resolution Imaging Science Experiment (HiRISE) camera will attempt to take an image of Curiosity as it descends to the surface (green).
HiRISE is one of six instruments on NASA's Mars Reconnaissance Orbiter. The University of Arizona, Tucson, operates the orbiter's HiRISE camera, which was built by Ball Aerospace and Technologies Corp., Boulder, Colo. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Reconnaissance Orbiter Project for NASA's Science Mission Directorate, Washington. Lockheed Martin Space Systems, Denver, built the spacecraft. (No audio)
This artist's animation shows how NASA's Curiosity rover will communicate with Earth via two of NASA's Mars orbiters, Mars Reconnaissance Orbiter and Odyssey. As the rover descends to the surface of Mars, it will send out two different types of data: basic radio-frequency tones that go directly to Earth (pink dashes) and more complex UHF radio data (blue circles). Odyssey will pick up the UHF signal and relay it immediately back to Earth (seen as a beam of small blue circles). Meanwhile, Mars Reconnaissance Orbiter will record the UHF data and play it back to Earth at a later time.
Back on Earth, the rover's signals are picked up by large antenna dishes at NASA's Deep Space Network (DSN), which has three complexes in Goldstone, Calif., Madrid, Spain and Canberra, Australia. The DSN sends the information to Curiosity's mission control at NASA's Jet Propulsion Laboratory, Calif. (No audio)

Curiosity's dramatic landing on Mars is the most difficult and nail-biting part of the whole mission. This 60-second video from NASA's Jet Propulsion Laboratory shows what it takes to touch down successfully.
Curiosity is a big part of what it means to be human. It's also the name of NASA's next Mars rover. This 60-second video from NASA's Jet Propulsion Laboratory shows how one type of curiosity can inspire another.
NASA began a historic voyage to Mars with the Nov. 26, 2011, launch of the Mars Science Laboratory, which carries a car-sized rover named Curiosity. Liftoff from Cape Canaveral Air Force Station aboard an Atlas V rocket occurred at 10:02 a.m. EST (7:02 a.m.
Transporting the Curiosity rover from its birthplace in Pasadena, California to Cape Canaveral, Florida, took countless hours and careful planning and preparation. The precious rover was placed onto a flatbed truck using a forklift; was driven down the highway for several miles and flown on a military transport plane for its cross country trip.
This 11-minute animation depicts key events of NASA's Mars Science Laboratory mission, which will launch in late 2011 and land a rover, Curiosity, on Mars in August 2012. (Audio: mechanical sounds only)
This episode (part 4 of a 4 part series) shows Mars team members having a little fun on April 1, 2010 (April Fool's) at the end of an exhausting parachute test campaign.
