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
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
Discover how scientists plan to use data from the GRAIL mission and a map of the Moon's gravitational field to learn about its internal structure. By comparing data about the Moon's gravity with information about its topography, scientists can gain a better understanding of the Moon's formation and
While the Moon is Earth's only natural satellite, there are thousands of artificial satellites circling our planet for navigation, communications, entertainment, and science. These satellites are an integral part of our everyday life, and they provide a source for scientific data unavailable from Ea
Explore the exciting discoveries from two NASA missions to study comets, Stardust and Deep Impact, which collected valuable data about the nature of comets. The Stardust spacecraft was designed to capture dust particles from comet Wild 2 and deliver them to Earth for analysis. The Deep Impact missio
Tools such as saws, hammers, and levers are designed to make work easier. Sometimes, the environment in which a person works dictates whether or not a certain tool will get the job done. In the microgravity environment of space, astronauts are often required to do experiments or simple repairs. On E
In this video from NASA, learn about the history of defining a planet, and examine how classification changes based on new knowledge. Our understanding of the solar system has evolved since the ancient Greeks, who first used the word planetes to distinguish the objects that moved against the backdro
