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
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
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
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
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
Take a tour of the Moon's surface features in this video from NASA. Images and topographic maps show craters, rocks, mountains, basins, and valleys, including the Orientale basin, Shackleton crater, South Pole-Aitken basin, Tycho crater, Aristarchus plateau, Mare Serenitatis, Compton-Belkovich volca
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
Since its launch is 1990, the Hubble Space Telescope has provided scientists with a vast amount of quality data and has contributed to a number of important discoveries. One of the best-known images — the Hubble Deep Field — shows some of the earliest and faintest galaxies ever seen. In this video s
