RapidScat Mission to Monitor Ocean Winds Ends

On Sept. 21, 2014, NASA scientists and engineers launched RapidScat toward the orbiting International Space Station, 250 miles above Earth’s surface, with a few objectives in mind: improve weather forecasting on Earth, provide cross-calibration for all international satellites that monitor ocean winds, and improve estimates of how ocean winds change throughout the day. Following the

Geospatial Science Identifies High-Risk Flooding Areas in Egypt

Researchers from UT Dallas and other universities developed geospatial science methods to help the Egyptian government determine how to avoid flooding in a coastal mountain region. The government wants to develop the area for tourism, but flash flooding and associated hazards have hampered efforts, according to Dr. May Yuan, Ashbel Smith professor of GIS. “We

CubeSats Need Powerful Antennas in Small Packages

Scientists at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, Calif., have been working on the tricky problem of CubeSat transmission antennas, which must be small enough for these diminutive devices yet still transmit data through the huge expanses of space. “It’s like pulling a rabbit out of a hat,” said Nacer Chahat, a specialist in

First Space-Based View of Human-Made Carbon Dioxide

Scientists produced the first global maps of human emissions of carbon dioxide ever made solely from satellite observations. The maps, based on data from NASA’s Orbiting Carbon Observatory-2 (OCO-2) satellite and generated with a new data-processing technique, agree well with inventories of known carbon dioxide emissions. No satellite before OCO-2 was capable of measuring carbon

Historical Records May Underestimate Sea-Level Rise

A new study using NASA satellite data finds that tide gauges—the longest and highest-quality records of historical ocean water levels—may have underestimated the amount of global average sea-level rise that occurred during the 20th century. A research team led by Philip Thompson, associate director of the University of Hawaii Sea Level Center in the School

Rwanda Launches World’s First National Drone Delivery Service

Throughout the developing world, access to lifesaving and critical health products is hampered by “the last-mile problem”: the inability to deliver needed medicine from a city to rural or remote locations due to lack of adequate transportation, communication and supply chain infrastructure. To lessen this problem, the Rwandan government will begin using drones to make

Variety of Sensors Tracked Hurricane Matthew

As Hurricane Matthew developed into a Category 4 hurricane that pummeled the Caribbean and southeastern United States, killing more than 1,000 people, disrupting electricity and other utilities to hundreds of thousands, and causing billions of dollars in economic damage, many of the world’s satellites and sensors were tuned to the storm, and recorded its path

Drone Adds IBM Watson for Cognitive Inspection

IBM and Aerialtronics introduced the first commercial drones featuring cognitive computing capabilities from the IBM Watson Internet of Things (IoT) Platform on IBM Cloud. Aerialtronics vehicles provide inspection services for global organizations across multiple industries, from monitoring city traffic patterns to inspecting wind turbines, oil rigs and cell-tower optimization. Aerialtronics’ commercial drones are the first

Teledyne Optech Teams Up with The Ocean Cleanup to Study the Great Pacific Garbage Patch

Teledyne Optech is pleased to announce it has partnered with The Ocean Cleanup in their Aerial Expedition research mission, where the Optech CZMIL (Coastal Zone Mapping and Imaging Lidar) successfully carried out the first in a series of low-speed, low-altitude survey flights across the Great Pacific Garbage Patch. Every year, about eight million tons of

NASA Aircraft Measuring Mid-Atlantic Greenhouse Gases

NASA is conducting low-level aircraft flights measuring greenhouse gases over the U.S. mid-Atlantic region for the CARbon Airborne Flux Experiment (CARAFE), which will measure the exchange of greenhouse gases such as carbon dioxide and methane between Earth and the atmosphere. Water vapor, temperature and vertical wind measurements also will be taken. “The direct measurements of
