NASA Measures ‘Dust on Snow’ to Help Manage Watersheds

Hydrologists at the Colorado Basin River Forecast Center are providing streamflow forecasts for watersheds within the Colorado River Basin, which includes some of the most parched land in the United States. “The forecasts we get from the center provide crucial information for managing our water resources and reservoir facilities,” said Dave Kanzer, a deputy chief

Sun Calendar Shows Solar Cycles Seen by Satellite

The SWAP camera onboard the European Space Agency (ESA) Proba-2 satellite takes advantage of extreme ultraviolet wavelengths to capture the hot turbulent atmosphere of the Sun’s solar corona. To illustrate what SWAP does and what it can teach, ESA and the Royal Observatory of Belgium collected and published 366 solar images—one for each day of

UK Space Agency Bolsters Partnership Program, Forests 2020 Project

  As part of the UK Space Agency’s recently launched International Partnership Programme (IPP) and its related Forests 2020 project, the agency awarded a contract worth more than £14 million to sustainability software and data company Ecometrica. The Forests 2020 project is expected to help countries improve management and protection across 300 million hectares of

Space Laser Reveals Cycle of Polar Phytoplankton

A new study using a NASA satellite instrument orbiting Earth found that small, environmental changes in polar food webs significantly influence the boom-and-bust cycles of phytoplankton. These findings, recently published in Nature Geoscience, will supply important data for ecosystem management, commercial fisheries and understanding of the interactions among Earth’s climate and key ocean ecosystems. “It’s

Seized Underwater Drone Raises Tension between U.S., China

The Chinese seizure of a U.S. underwater drone in waters near The Philippines is raising international concern as well as highlighting the growing strategic and tactical significance of unmanned underwater vehicles (UUVs). According to a statement from Pentagon spokesman Peter Cook, “Using appropriate government-to-government channels, the Department of Defense has called upon China to immediately

USGS Report Cites Fluid Injection as Cause for Increased Earthquakes

The central United States has undergone a dramatic increase in seismicity during the last six years. From 1973-2008, there was an average of 24 earthquakes of magnitude 3 and larger per year. From 2009-2014, the rate steadily increased, averaging 193 per year and peaking in 2014 with 688 earthquakes. So far in 2015, there have

Arctic Sea Ice at Record Lows

Every northern fall and winter, cooling ocean and air temperatures cause the floating cap of Arctic sea ice to grow from its annual minimum extent toward a maximum between February and April. So far in 2016, however, the Arctic Ocean and neighboring seas have been slow to freeze, setting both daily and monthly record lows.

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
