It was midafternoon, but it was dark in an area in Boulder, Colorado on Aug. 3, 1998. A thick cloud appeared overhead and dimmed the land below for more than 30 minutes. Well-calibrated radiometers showed that there were very low levels of light reaching the ground, sufficiently low that researchers decided to simulate this interesting event with computer models. Now in 2017, inspired by the event in Boulder, NASA scientists will explore the moon's eclipse of the sun to learn more about Earth's energy system.

Satellite altimetry—long established as an essential tool for open-ocean oceanography and sea level studies—is now also supporting diverse applications in the coastal zone. These applications include monitoring storm surges and mapping coastal dynamics, wind, and waves, information that can be assimilated in coastal models.
Despite the ongoing development of a fleet of small launch vehicles, both launch providers and customers continue to see demand for flying small satellites as secondary payloads on larger rockets.
Airbus, together with non-profit organisation The Forest Trust (TFT) and radar satellite imagery expert SarVision, have launched Starling, an innovative satellite service enabling companies to demonstrate how they are implementing their ‘No Deforestation' commitments.

Do three events constitute a trend? For many in the Earth-observation industry, the answer seems to be yes.
'Sentinel Stories' is presented by Malì Cecere. In this video, produced by ESA, Professor Andreas Kääb of the University of Oslo describes his work with data from the Copernicus Sentinel satellites and what sort of benefits these bring to him and his team.

Last year was the hottest on record, Arctic sea ice is on the decline and sea levels continue to rise. In this context, satellites are providing us with an unbiased view of how our climate is changing and the effects it is having on our planet.

Wearing white sneakers, a cowboy hat and overalls, Bernie Fowler walks into Maryland's Patuxent River every June to see how deep he can go and still see the tops of his shoes. As a young man he could see his feet on the river bottom as he stood chest-deep to net blue crabs. Now in his nineties, he ventures into the river to assess the water clarity. Fowler has been collecting this data point for the past 29 years and counting, calling it "sneaker depth".

A British company has announced its intention to launch a big constellation of Earth observation satellites.
Work on exploiting new satellite instruments that will provide unprecedented details of the weather at different levels of the atmosphere is making good progress, an international meeting hosted by ECMWF has heard.
X-Cubesat, the satellite designed by students from the French École Polytechnique, was placed in orbit from the International Space Station on 17 May at 3.45am (local). The cubesat is operational, and the very first telemetry was received by an amateur radio station in the Netherlands and sent to the École Polytechnique.
AN UNMARKED WHITE semi-truck rests on orange steel plates—Rent Me, they proclaim—protecting the soft ground outside a glass-fronted office building in Westminster, Colorado. Inside the cargo container, locked up in refrigerated drives, is a photo album of Earth. Over 17 years, a company called DigitalGlobe has painstakingly collected those images from its high-resolution satellite network. And on this May morning, it's set to ship those precious 100 petabytes to Amazon and its cloud-based Web Services.
Fires, whether naturally occurring or man-made, have substantial impacts on both the landscape and air quality. Fortunately, satellites can detect and monitor fires large and small, and provide data on a range of factors, including location, duration, size, temperature and intensity.
