Envisat and ERS-2, ESA's two veteran Earth missions, have completed a second tandem observation campaign. The technique involved flying the two satellites in precisely coordinated orbits, generating valuable new radar data for modeling Arctic terrain. Both Envisat and ERS-2 are equipped with synthetic aperture radar (SAR) instruments that can generate highly accurate radar images of any region of the Earth's surface. By combining two or more SAR images taken by one satellite of the same site,...

A newly initiated campaign marks an important step in preparing for how data from the Sentinel-1 European Radar Observatory will be used for applications such as land-cover mapping and crop management. Sentinel-1 is the first of the five missions that ESA is developing for the GMES initiative. Sentinel-1 is a constellation of two C-band radar satellites that will provide continuous all-weather, day and night imagery for use in a range of diverse services "“ from marine and land...

Studying satellite radar data from ESA's Envisat and the Italian Space Agency's COSMO-SkyMed, scientists have begun analyzing the movement of Earth during and after the 6.3 earthquake that shook the medieval town of L'Aquila in central Italy on 6 April 2009. Scientists from Italy's Istituto per il Rilevamento Elettromagnetico dell' Ambiente (IREA-CNR) and the Istituto Nazionale di Geofisica e Vulcanologia (INGV) are studying Synthetic Aperture Radar (SAR) data from these satellites to map...

Using radar images acquired by ESA satellites from 1992 to 2006, scientists have for the first time been able to monitor the long-term behavior of Mt. Etna, Europe's highest and most active volcano. This unprecedented time series of Synthetic Aperture Radar (SAR) observations from ESA's ERS-1, ERS-2 and Envisat satellites provided crucial information for understanding how the volcano's surface deformed during the rise, storage and eruption of magma. Changes in surface deformation, such as...

Using satellite radar data, NASA-funded scientists have observed, for the first time, the healing of subtle, natural surface scars from an earthquake that occurred on a "buried" fault several miles below the surface-a fault whose fractures are not easily observed at Earth's surface. Reporting in the March 5 issue of Nature, geophysicist Eric Fielding of NASA's Jet Propulsion Laboratory in Pasadena, Calif., describes how so-called "buried" faults are not so hidden after all. Using the...

ESA has announced three candidate Earth Explorer mission concepts to progress to the next phase of consolidation. This selection is part of the user-driven process that will lead to the launch of the Agency's seventh Earth Explorer satellite in the 2016 time frame. Last week ESA's Programme Board for Earth Observation decided on three Earth Explorer missions that will undergo Feasibility Studies. The decision was based on recommendations made by ESA's Earth Science Advisory Committee (ESAC)...

More than 200 scientists from around the world have attended the weeklong POLinSAR 2009 workshop hosted at ESRIN, ESA's Earth Observation centre in Frascati, Italy. Discussions among the participants include new techniques for providing vital information on our planet that could help to combat global warming through carbon accounting, wetland preservation and improve climate models. Using the novel polarimetric mode of the PALSAR synthetic aperture radar (SAR) aboard Japan's ALOS satellite,...

 Using a NASA radar flying aboard India's Chandrayaan-1 spacecraft, scientists are getting their first look inside the moon's coldest, darkest craters. The Mini-SAR instrument, a lightweight, synthetic aperture radar, has passed its initial in-flight tests and sent back its first data. The images show the floors of permanently-shadowed polar craters on the moon that aren't visible from Earth. Scientists are using the instrument to map and search the insides of the craters for water ice....

The idea of a white Christmas may seem magical for many of us, but spare a thought for a team of scientists forgoing the festive season to take part in a novel campaign being carried out in one of the most inhospitable regions on Earth to support ESA's ice mission CryoSat. German scientists from the Technical University of Dresden and the Alfred Wegener Institute are spending up to four months venturing out onto the vast frozen reaches of what is known as the 'blue ice' region near the...

Wind and wave data from ESA's Envisat satellite radar are being used to observe meteorological conditions in the track of the Vendee Globe solo round-the-world yacht race. CLS, a subsidiary of the French Space Agency (CNES), acting through its new radar applications division (formerly the BOOST Technologies Company), is using the race to demonstrate the ability of Envisat radar imagery to operationally observe oceans at high resolution. Based on the trajectory and speed of the boats, CLS is...

Endeavour launched from Kennedy Space Center on April 9. 1994 at 7:05 AM EDT and landed at Edwards AFB on April 20 at 9:54 AM PDT. The shuttle orbited 183 times at an altitude of 121 nautical miles at an inclination of 57 degrees and travelled 4.7 million miles. The mission lasted  11 days, 5 hours, 49 minutes, and 30 seconds. The primary payload was the Space Radar Laboratory (SRL-1), located in payload bay; activated by crew and operated by teams on ground. SRL-1 included the Spaceborne...
