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 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
Learn how a giant storm on Saturn sent temperatures soaring in this video from NASA's Goddard Space Flight Center. About once a Saturn year, the planet develops a massive storm called a Great White Spot. Planetary scientist Brigette Hesman describes observations of the storm that erupted on Saturn i
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
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 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 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
Explore whether Mars is alive -- geologically or biologically -- in this video from NASA. Satellite images and the recent discovery of water ice on the surface of Mars suggest liquid water is flowing beneath the surface, which could make it a habitable planet. The controversial discovery of methane
