Spy Saturn, Jupiter, Venus and Mars as they make appearances next to the moon this month, making them easy and fun to spot in the sky.

Curiosity will spend the holidays at a location on Mars dubbed "Grandma's House."

The "keys" to NASA's Mars rovers are in the capable hands of the official rover drivers. Learn how they operate the vehicles from millions of miles away in this 60-second video from NASA's Jet Propulsion Laboratory.

This 64-frame movie of asteroid Toutatis was generated from data by Goldstone's Solar System Radar on Dec. 12 and 13, 2012. In the movie clips, the rotation of the asteroid appears faster than it occurs in nature.

JPL celebrates 50 years of stellar firsts starting with world's first planetary encounter by Mariner 2.

This is the first footage of one orbiting robotic spacecraft taken by another orbiting robotic spacecraft at Earth's moon. "Flow," one of two satellites making up NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission, captured this video of NASA's Lunar Reconnaissance Orbiter (LRO) as it flew by at a distance of about 12 miles (20 kilometers) on May 3, 2012. LRO is the single bright pixel that moves from top left to bottom right. The moon's south polar region is in the background, much of which is in darkness.

On Dec. 14, 1962, NASA's Mariner 2 spacecraft flew by Venus, making the United States the first country to complete a successful mission to another planet.

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.

NASA's Curiosity Mars rover team wraps up its scientific study at Rocknest.

This movie shows the 'Bouguer' gravity of Earth's moon based on data from NASA's Gravity Recovery and Interior Laboratory (GRAIL) and topography from the Lunar Reconnaissance Orbiter's Lunar Orbiter Laser Altimeter.

This animation depicting the crustal thickness of the moon was derived using gravity data from NASA's GRAIL mission and topography data from NASA's Lunar Reconnaissance Orbiter.

NASA's GRAIL mission took this flyover video above the Mare Orientale basin of Earth's moon.

This movie shows the variations in the lunar gravity field as measured by NASA's Gravity Recovery and Interior Laboratory (GRAIL) during the primary mapping mission from March to May 2012.

How samples are delivered and then tested in the Sample Analysis at Mars (SAM) suite on the Mars Curiosity rover.
