A simulated flyover of the most intriguing landmarks on giant asteroid Vesta, as seen by NASA's Dawn spacecraft.

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 talks to Earth with the help of orbiting satellites.

This color panorama shows a 360-degree view of the landing site of NASA's Curiosity rover, including the highest part of Mount Sharp visible to the rover.

Curiosity performs a series of firsts this week -- flexing its arm, laser-zapping a rock and rolling on its wheels

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. Image credit: NASA/JPL-Caltech/MSSS

This simulation shows the first test drive of NASA's Curiosity rover.

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.

This video steps viewers through a portion of the choreography needed to land NASA's Curiosity rover on Mars. It starts with a computer simulation from NASA's Eyes on the Solar System program and uses actual images from Curiosity's Mars Descent Imager. It ends with a high-resolution color image from Curiosity's Mast Camera. Credit: NASA/JPL-Caltech/MSSS

Mission team members for InSight, the new Mars lander mission selected by NASA to launch in 2016, explain how the spacecraft will advance our knowledge of Mars' history and rocky planet evolution.

This video drops in on mission control for NASA's Voyager spacecraft as Voyager 1 sends back data from the far reaches of our solar system.

This animation depicts the location of the ChemCam instrument at the top of the mast on NASA's Mars rover Curiosity and the field of view of the instrument's camera, called the Remote Micro-Imager. In the animation, the camera is pointed at ChemCam's calibration target on Curiosity's deck.

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.

Curiosity remains busy on Mars by checking out her instruments and getting ready for her first test drive.
