Eliminating the Need for Payload-Specific Coupled Loads Analyses Without Mission Risk

Marshall Space Flight Center, Alabama Amore efficient structural verification process for small satellites has been demonstrated. This new process eliminates the need for payload-specific coupled loads analysis (CLA) and simplifies structural testing while not increasing mission risk. The process entails the following:

Moon Tours Android

NASA’s Jet Propulsion Laboratory, Pasadena, California This Android app provides a native interface to the Lunar Mapping and Modeling Portal’s (LMMP) lunar data archive and analysis tools. It complements the iOS app previously released, incorporating a very similar feature set. Both apps contain a subset of the functionality available in the desktop/Web version. Compared to the iOS version of the LMMP, the Android version provides the additional tools necessary to perform elevation analysis and perimeter/area measurements.

Executive Perspectives: Internet of Things

ALEX IUORIO Senior Vice President, Supplier Management and Business Development Avnet Electronics Marketing Americas Phoenix, AZ www.em.avnet.comIn a 1926 interview, inventor Nikola Tesla stated: “When wireless [technology] is perfectly applied, the whole Earth will be converted into a huge brain.” Though Tesla’s remark was made four decades before the earliest incarnations of Internet technology were introduced by the U.S. Advanced Research Projects Agency, it is an uncanny depiction of the power and potential we see today from the Internet of Things (IoT).

The Advanced Data Analytics Platform (ADAPT): Concept, Design, Architecture, and Operation

Goddard Space Flight Center, Greenbelt, Maryland NASA scientists are uniquely positioned to research and understand the processes affecting the Earth’s climate. To study these important processes, scientists must address the Big Data challenges posed by working with massive amounts of observational and climate model output data. The Advanced Data Analytics Platform (ADAPT) is a cyber infrastructure resource specifically designed to reduce the friction between scientists and data. The system includes a high-performance storage cloud surrounded by large-scale compute resources. A very high-performing network enables fast access to the data stored within ADAPT. Furthermore, the system allows users to bring their applications to the data and define the environment in which those applications run. The science results can then be stored for future analysis or shared through static and dynamic data services within ADAPT without having to move the data or make additional copies. The agility, flexibility, and extensibility of the system make it ideal for NASA scientists to produce science results quickly by analyzing large data sets.
