CryoSat is ESA’s (European Space Agency) first ice mission. Launched in April 2010, it provides multi-year elevation data at latitudes never reached before by a satellite altimeter. The satellite has sophisticated technologies to determine variations in the thickness of polar sea ice to monitor changes in the vast ice sheets that overlie Greenland and Antarctica. This application is a gateway to knowing what the mission is about, how it works and what the elements of the space and ground segment that makes this mission unique are. It includes also a dedicated section that allows one to discover and visualize real CryoSat measurements over our planet: a remarkable tool for students and scientists engaged in using CryoSat products or interested in satellite engineering. Features: - Description of the CryoSat mission: space and ground segment - Large selection of photos and videos on a wide range of topics related to CryoSat - Latest mission operations news - Striking CryoSat 3D model with explanations of the different platform and payload elements - World map with orbit position of the satellite - Satellite visibility over selected ground stations and local position - Automatic update of the CryoSat orbit - Impressive visualization of real Cryosat measurements over the Earth with vertical profiles and easy geographical localization - Access to several geophysical parameters measured by the satellite …and much more Continued use of GPS running in the background can dramatically decrease battery life. In the 3D environment: - swipe/pinch to rotate/zoom the satellite model - triple touch to reset position

The ISS explorer is an interactive tool for exploring the parts and pieces of the International Space Station (ISS). The application allows the user to view a 3D model of the ISS, rotate it, zoom into it, and select different parts and pieces. When the application starts, you can see a view of the entire ISS with category labels. Tabs are available on the left hand side of the screen which allow you access to information, the hierarchy, settings and application information. From this point, you can zoom into the station, revealing more labels of visible parts. The station can also be rotated to view from different angles. If a part is selected, the part is isolated so that you can focus on the specific piece. The information tab shows information about the currently isolated part. Inside the hierarchy tab, you can turn parts on or off, turn labels for parts on or off, turn parts transparent, or select a part to focus on. The parts are organized in a hierarchy to allow for systems to be described and displayed. This includes things such as truss, modules, and external platforms. The Information tab shows information about the current isolated part, system, or the full ISS if the entire station is shown.
