Since the late 1800s, observers have searched the polar skies for elusive, high-flying clouds that shine in the darkness.

New study found that electrons can reach ultra-relativistic energies for very special conditions in the magnetosphere when space is devoid of plasma.

Arabian Peninsula A Trap For Summer Dust

Intense winds blowing from Africa through a mountainous gap on the western Red Sea coast have led to a buildup of summer dust over the Arabian Peninsula in the past decade. This increasing dust load could have long-term health and global climatic implications.

The University of Texas at Austin team that led a twin satellite system launched in 2002 to take detailed measurements of the Earth, called the Gravity Recovery and Climate Experiment (GRACE), reports in the most recent issue of the journal Nature Climate Change on the contributions that their nearly two decades of data have made to our understanding of global climate patterns.

Underground water reserves in California's Silicon Valley rebounded quickly from the state's recent severe drought, demonstrating the success of aggressive conservation measures, according to a new space-based study by NASA and university scientists.

In an effort to better understand our changing planet and our impact on it, NASA kicked off its Earth Expeditions campaign on March 23.

How can Earth observation research explore the new challenges and opportunities created by the rapid advances in information and communications technologies?

A new, low-cost cubesat mission will demonstrate technology needed to measure the absolute imbalance in the Earth's radiation budget for the first time.

A team of scientists has won a berth on a tiny satellite to explore one of NASA's most important frontiers in climate studies: the imbalance in Earth's energy budget and the extent to which fast-changing phenomena, like clouds, contribute to that imbalance.

Oxygen to the core

An international collaboration including researchers from Lawrence Livermore National Laboratory has discovered that the Earth's core formed under more oxidizing condition's than previously proposed.

"DigitalGlobe (DGI), a leading global provider of high-resolution earth imagery solutions, today announced an agreement with the Enough Project to continue providing unrivaled imagery and analysis services to monitor evidence of bombings, razed villages and possible threats to civilians in Sudan in an effort called the Satellite Sentinel Project (SSP). In addition to the imagery and analysis provided under the terms of this new agreement, DigitalGlobe will also contribute additional in-kind services." More

Rio+20 Summit and Space Observations

The Rio+20 summit on promoting jobs, clean energy and a more sustainable use of our planet's resources closed today after three days of talks. During the summit, the role of Earth observation in sustainable development was highlighted.

NASA's Aqua satellite passed over the High Park Fire in Colorado on June 10, 2012 at 2030 UTC (4:30 p.m. EDT) and captured this visible image of the thick pall of smoke blowing east, just north of Fort Collins.

Cubesat-based Earth Science Pathfinders

NASA Request for Information (RFI) - Future Space Validation of Earth Science Technologies

"ESTO is funding several CubeSat-based technology validations as part of a pathfinder process. ESTO is now interested in defining the parameters of a possible future competitive program to space validate selected Earth science technologies. That future program is the focus of this RFI. The program may consist of one or two parts. The first part would be a continuation of the current CubeSat-based validations or validation using suborbital reusable launch vehicles (sRLV). The second part would be a somewhat more robust program, expanding the class of possible technologies to validate. NASA is issuing this RFI to seek the high-level details of various projects which might fit in either one or the other of these classes."
