Radar Interferometer for Topographic Mapping of Glaciers and Ice Sheets

A report discusses Ka-band (35-GHz) radar for mapping the surface topography of glaciers and ice sheets at high spatial resolution and high vertical accuracy, independent of cloud cover, with a swath-width of 70 km. The system is a single- pass, single-platform interferometric synthetic aperture radar (InSAR) with an 8-mm wavelength, which minimizes snow penetration while remaining relatively impervious to atmospheric attenuation.

Origin 8

OriginLab Corp., Northampton, MA, has announced Origin 8 Windows-based data analysis and graphing software that operates around a revamped workbook space, which allows results of an analysis to be placed into a worksheet within a raw data’s workbook. Parameter values, statistics, and related analysis graphs are available whenever looking at the original data. A new multi-sheet workbook feature keeps all related data, analyses, and graphs together. Sheets can be moved, added, inserted, or deleted. Workbooks in the new version also contain a new feature that allows users to embed graphs and images within cells to create a custom report. Another new feature called Sparklines allows for a special type of embedded graph found within worksheet column headers. Column Sparklines provide brief profiles of the column’s data, providing users with an at-a-glance profile of the data in a given column. The aspect ratio of column Sparklines can be changed to show more data trends by changing the column width and/or row height. A graph can be copied to the clipboard as a Sparkline to display a small, word-sized graphic within text documents.

System Locates Passengers Who Contaminate Airline Cabins

Researchers at Purdue University have developed a system that uses mathematical models and sensors to locate passengers releasing hazardous materials or pathogens inside airline cabins. The system can track a substance to an area the size of a single seat. The technique could enable officials to identify passengers responsible for the unintentional release of germs, such as contagious viruses, or the intentional release

Karen Whitley, Expandable Structures for Exploration Task Lead

NASA Langley Research Center, Hampton, VA Karen WhitleyNASA plans to return to the Moon by 2020. For a sustained lunar presence, however, astronauts need habitats that can support them and their experments. To this end, researchers at NASA Langley, working with NASA contractor ILC Dover (Frederica, DE), are developing the “planetary surface habitat and airlock unit,” a prototype inflatable structure that could be deployed on the lunar surface. Karen Whitley is the project lead.

Battery Power Source Options for Mission-Critical Applications

Selecting power source technology for mission critical devices is crucial to ensure success. Whether it is a monitor at the bottom of the ocean, a drill system at 30,000 feet into the Earth’s crust, or hand warmers on an astronaut in Earth orbit, the cost of failure in these situations far outweighs the cost of a battery. Equipment used in these and other mission- critical situations must perform under environmental conditions that would destroy most commercially available components and energy sources. Every element must be capable of operating in environments where extremes in temperature, pressure, shock, vibration, and corrosive exposure are the norm. Selecting batteries for these vital activities must include consideration for the high level of reliability and performance required to ensure these significant and often costly programs stay on target.

Power Complex Protects NASA Test Equipment

Centralized Uninterruptible Power Supply (UPS) Lee Technologies Fairfax, VA 703-968-0300 NASA’s Stennis Space Center in Bay St. Louis, MS, is NASA’s primary site for rocket propulsion testing. It is also home to the Applied Research and Technology Project Office (ARTPO), which supplies project management to support NASA’s science and technology goals. Recently, Stennis awarded Lee Technologies a contract to construct a centralized uninterruptible power supply (UPS) and emergency generator. Under the terms of the contract, Lee Technologies will partner with Z Corporation in Burlington, MA, to construct the power complex at Stennis.
