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
Discover why Mercury has a tail like a comet, and why its poles are covered in ice despite its close proximity to the Sun. Mercury, the closest planet to the Sun, rotates three times on its axis every two of its years. Despite having temperatures that are hot enough to melt lead, the tilt of the pla
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
Explore the complex process of designing and building a satellite using the MAVEN mission to Mars as an example. Plans for the MAVEN satellite went through a thorough review of the concept, budget, and risk analysis before proceeding to the next step of the process. Even after the design review is a
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
In "Space Rock Census" Amy Mainzer, principal investigator for the Wide-field Infrared Survey Explorer (WISE) mission, reveals some new observations about space rocks in our solar system in these videos from NASA Jet Propulsion Laboratory. The WISE mission is helping scientists understand the true n
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
