Discover the instruments that Curiosity, a rover on Mars, used to gather and analyze soil samples in this video from NASA's Jet Propulsion Laboratory. In 2012, Curiosity took its first scoop of Martian soil to test and analyze from an area called Rocknest. One of the project scientists describes how
Discover how and why Curiosity, the Mars rover, measures wind and radiation on Mars. Mars Science Laboratory scientist Ashwin Vasavada describes two of the instruments onboard the rover that study Mars' present environment. The Radiation Assessment Detector (RAD) measures high-energy radiation from

Learn about the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission to Mars in this video from NASA's Goddard Space Flight Center. Mars does not have a global magnetic field like Earth but does have patches of magnetic fields. Scientists use magnetometers to study the planet's magnetic anomalies.
Tour three Martian landscapes and find out how erosion and water affected the surface of Mars, in this video adapted from NASA. Flyover images created from HiRISE (High Resolution Imaging Science Experiment), an instrument on board the Mars Reconnaissance Orbiter, show the structure and composition
Learn about the discovery of conditions that would have been suitable for life on ancient Mars. In 2013, the Mars Science Laboratory (MSL) science team released initial findings from its first drilled sample using the Curiosity rover. MSL scientist Joel Hurowitz describes the sedimentary rock sample
Explore what makes Mercury so mysterious and what scientists are learning from NASA's first Mercury mission in 30 years. For the MESSENGER mission, NASA launched a probe and guided it toward Mercury using a technique called "solar sailing." The probe is studying the make-up of the planet's inner cor
Launched in September 2011, find out about the Gravity Recovery and Interior Laboratory (GRAIL) mission to measure the gravitational field of the Moon and study how the Moon developed over time. Animations illustrate technical aspects of the mission's design, including the launch, orbital insertion
Learn about Earth's close encounter with asteroid 2012 DA14 on February 15, 2013, in this video from NASA. Asteroid 2012 DA14 passed safely about 17,000 miles (27,000 kilometers) from Earth's surface. Its orbit was well known and scientists were not worried about a possible collision. NASA observes
Learn about powerful cyclones seen at Saturn's north and south poles in this video from NASA's Jet Propulsion Laboratory. From a distance, Saturn appears to be serene; however, the Cassini spacecraft has provided detailed views that show the planet's active atmosphere. A giant cyclone (with a diamet
Learn what comets are and how they inform us about the early solar system, in this video adapted from NASA. Comets, which are made of frozen gases, ice, dust, and rock, are typically in a deep freeze in the outer solar system. But when a comet nears the Sun, it loses streams of gases and forms a com
