Europe's Galileo Navigation System Adds Two Satellites

Europe's Galileo Navigation System Adds Two Satellites

The European Union-funded Galileo satellite navigation system added its 13th and 14th satellites after a successful launch atop a Soyuz rocket from French Guiana on May 24, 2016. Nearly four hours after liftoff, the twin Galileos were deployed into orbit approximately 23,522 kilometers above Earth.

Complex Data Made Easy

12 May 2016 — While the growing volume information from satellites observing Earth offers a unique opportunity for science and applications, it is sometimes difficult to make sure these complex data streams are exploited to their full potential. ESA is addressing...

Antarctic Icebergs Break Free

Antarctic Icebergs Break Free

On April 7, 2016, multiple satellites captured the birth of two large icebergs that were shed along a crack on Antarctica's Nansen Ice Shelf during persistent strong offshore winds. The icebergs currently pose no threat to shipping, but they may pose a threat to scientific instruments moored to the seafloor to monitor climate change.

Mysteries of Wobbling Earth Solved

Mysteries of Wobbling Earth Solved

Using satellite data on how water moves around Earth, NASA scientists solved two mysteries about wobbles in the planet’s rotation. Earth's spin axis drifts slowly around the poles; the farthest away it has wobbled since observations began is 37 feet (12 meters). These wobbles don't affect daily life, but they must be taken into account to get accurate results from GPS, Earth-observing satellites and ground-based observatories.

Preparing for More Radar Vision

The Sentinel-1B satellite has arrived in French Guiana to be prepared for liftoff on 22 April. It will join its identical twin, Sentinel-1A, in orbit to provide more radar views of Earth for Europe’s Copernicus environmental monitoring effort. The satellites each...
