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

Drones May Provide a Big Lift to Agriculture when FAA Allows Their Use

The big boom in unmanned aircraft may come from what’s known as precision agriculture — using high-tech systems to help farmers increase yields and cut costs. In recent years, consumer-quality drones that are cheaper and easier to fly have become commonplace, but Federal Aviation Administration rules have restricted their civilian use to recreation and research

Personalizing Climate Change through Open Data and Apps

Government-released open data is fuelling a whole new level of innovation in sustainability. Moving beyond hackathons, today’s climate data partnerships are creating unique ventures that cross boundaries between business, government and academia. Recently, the geographic information system technology (GIS) company Esri held the Esri Climate Resilience App Challenge in conjunction with the White House’s Climate

Hurricane-Proof Drones Are the Storm Chasers of Tomorrow

Current hurricane-hunting planes gather data on winds, pressure, precipitation and temperature, but they can’t fly below about 5,000 feet because of extreme turbulence. Dropsondes, small cylindrical sensors that can be dropped from a plane, only provide a few minutes’ worth of data before falling into the ocean. A new unmanned aerial vehicle, however, will go

Smartphones and the Uncertain Future of ‘Spatial Thinking’

The rise in mobile navigation technology has, in just a few years, transformed the way we get around cities. In 2011, 35 percent of Americans had smartphones; by 2013, that had grown to 61 percent. Three-quarters of those people now use their phones for directions and location-based services. One in five Americans used the Google Maps app in June;

Concern About Earth Observation Measurement Longevity

Studying complex environmental systems, such as atmospheric chemistry and climate, requires a global, long-term view—the view from a satellite. Civilian Earth-observing satellites date to 1960, when NASA launched its first Television Infrared Observation Satellite to map cloud cover. Today, NASA counts 17 and the National Oceanic & Atmospheric Administration counts 15 active Earth-observing platforms in

Napa Quake Unleashes Groundwater

The earth’s mighty shifting – which caused about $400 million in damage to Napa, Sonoma and Solano counties – also mysteriously forced groundwater to the surface and into several dry or nearly dry creeks and streams in the region. Torrents of water have been flowing down Wild Horse and Green Valley creeks and another unnamed waterway
