Ceramic column grid array (CCGA) packages have been increasing in use based on their advantages of high interconnect density, very good thermal and electrical performance, and compatibility with standard surface-mount packaging assembly processes. CCGA...

There are specific NASA requirementsfor source-specific encapsulated microbial density for encapsulated organisms in non-metallic materials. Projects such as the Mars Science Laboratory (MSL) that use large volumes of non-metallic materials of planetary protection concern...

The Crew Exploration Vehicle Parachute Assembly System (CPAS) is the parachute system for NASA’s Orion spacecraft. The test program consists of numerous drop tests, wherein a test article rigged with parachutes is extracted or released from an aircraft. During such tests, range safety is paramount, as is the...

This software describes the transport and energy deposition of the passage of galactic cosmic rays in astronaut tissues during space travel, or heavy ion beams in patients in cancer therapy. Space radiation risk is a probability distribution, and time-dependent biological events must be...

The Multi-User Space (MUS) Link Extension system, a software and data system, provides Space Link Extension (SLE) users with three space data transfer services in timely, complete, and offline modes as applicable according to standards defined by the Consultative Committee for Space Data Systems (CCSDS)....

A control system has been developed for the Space Interferometer Mission (SIM) piezo stepping actuator. Piezo stepping actuators are novel because they offer extreme dynamic range (centimeter stroke with nanometer resolution) with power, thermal, mass, and volume advantages over existing motorized...

Optimal planning and scheduling for a communication network was created where the nodes within the network are communicating at the highest possible rates while meeting the mission requirements and operational constraints. The planning and scheduling problem was formulated...

Video-based altimetric and obstructiondetection systems for aircraft have been partially developed. The hardware of a system of this type includes a downward-looking video camera, a video digitizer, a Global Positioning System receiver or other means of measuring the aircraft velocity...

A NASA-funded sounding rocket mission will launch from an atoll in the Pacific. The mission will help scientists better understand and predict the electrical storms in Earth's upper atmosphere. Storms interfere with satellite communication and global positioning signals.

A "Smartphone Physical" debuted at the TEDMED conference in Washington D.C. this month. Using devices and attachments paired with an iPhone, patients were able to measure and record their blood pressure, lung function, weight, oxygen saturation, and eyesight. The technology, developed by...

Researchers from North Carolina State University have developed a new technique for creating stronger, lightweight magnesium alloys that have potential structural applications in the automobile and aerospace industries.

Recent progress in the engineering of plasmonic structures has enabled new kinds of nanometer-scale optoelectronic devices as well as high-resolution optical sensing.

Rice University engineering students are working on better ways to keep skyscrapers shiny.The WashBOT team of seniors based at Rice’s Oshman Engineering Design Kitchen is part of a multiyear robotics project to automate the process of cleaning recessed windows in buildings that present problems...

Studying volcanos can be hazardous work, both for researchers and aircraft. To penetrate such dangerous airspace, unmanned aerial vehicles (UAVs), especially those with electric engines that ingest little contaminated air, are an emerging and effective way to gather crucial data about volcanic...

When a current passes between two electrodes — one thinner than the other — it creates wind in the air between. If enough voltage is applied, the resulting wind can produce a thrust without the help of motors or fuel. This phenomenon, called electrohydrodynamic...

The installation of equipment into the James Webb Space Telescope requires patience and precision. To prepare for the installation of the actual flight equipment and ensure perfection in the installations, scientists need to practice with an identical test unit. Scientists at...

Taking a significant step toward improving the power delivery of systems ranging from urban electrical grids to regenerative braking in hybrid vehicles, researchers at the UCLA Henry Samueli School of Engineering and Applied Science have synthesized a material that shows high...

The Global Precipitation Measurement mission, or GPM, provides the next generation of rainfall measurements from space. The mission is designed to tap into the observational power of nine independent satellites flying around Earth, and combine their precipitation data into a single, global data...

An increasing number of medical professionals are embracing social media for sharing helpful information and providing personalized patient care. HealthTap, one of the newest networks, for example, is an online hub of 1.2 million doctors who field questions from patients around the world. Some say...

A nanosponge invented by engineers at the University of California, San Diego can safely remove many dangerous toxins from the bloodstream, including those produced by MRSA, E. coli, poisonous snakes, and bees.

New microbatteries, developed by researchers at the University of Illinois at Urbana-Champaign, out-power supercapacitors and could drive new applications in radio communications and compact electronics.The devices offer both power and energy. By tweaking their structure a bit, the researchers can tune them...
