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
http://www.hoTodi.tv shows how it's done! This part again deals with a very important but rather dull exercise! If you want to learn how to play bass or any other instrument, you have to understand that you do not only have to play your instrument correctly, it also has to sound properly and so it m

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 our solar system's largest planet, Jupiter, including its role in the evolution of the solar system in this video from NASA. Dramatic visualizations and satellite images show Jupiter's size compared with Earth, its fast rotation, and its dynamic cloud systems (including the famous Great Red
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
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
Discover how astronomers determined the unexpected brightening of an asteroid named Scheila was likely the result of an impact with a much smaller asteroid. This video from NASA looks at how the Swift satellite and the Hubble Space Telescope helped astronomers investigate what they thought was an un
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
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
