As fears grow that the Loop Current in the Gulf of Mexico could soon catch the oil slick and drag it south towards coral reefs in the Florida Keys, scientists are monitoring the situation closely with ESA's Envisat radar data. By combining surface roughness and current flow information with Envisat Advanced Synthetic Aperture Radar (ASAR) data of the spill, SAR image analysts are able to detect the direction in which the spill boundaries can drift. In these two ASAR images for April 29...

ESA's Envisat has captured the changes in direction of the rapidly-growing oil spill in the Gulf of Mexico as strong winds over the weekend pushed it around and hampered clean-up efforts. In these latest images, the oil spill is visible due east of the Delta National Wildlife Refuge extending into the Gulf. The white dots are oil rigs and ships. Wind can easily spread oil on the water, with the course determined by the wind's direction and speed. Following the explosion of the drilling rig on...

These ESA Envisat images capture the oil that is spilling into the Gulf of Mexico after a drilling rig exploded and sank off the coasts of Louisiana and Mississippi, USA, on April 22. In the black-and-white radar image the oil spill is visible as a dark grey whirl in the bottom right, while in the optical image it is seen as a white whirl. The Mississippi Delta is at top left, and the Delta National Wildlife Refuge extends out into the Gulf. Officials report that about 1000 barrels of...

Taking advantage of NASA's 'Operation Ice Bridge' campaign, measurements of Arctic sea ice have been made from an aircraft flying directly under CryoSat-2's orbital path. These measurements offer an early opportunity to check the quality of the newly launched CryoSat-2 satellite data over sea ice. Following the launch of ESA's CryoSat-2 ice mission April 8, the satellite's Synthetic Aperture Interferometric Radar Altimeter (SIRAL) was switched on and delivered its first radar echo data on...

Originally designed to monitor Earth for just three years, ESA's veteran ERS-2 satellite is still in orbit and going strong after 15 years of delivering essential data to improve our understanding of Earth and climate change. ERS-2 was launched on 21 April 1995 to follow on from the first European Remote-Sensing mission, ERS-1, which had been in orbit since 1991. At the time, these two satellites were the most sophisticated European Earth observation spacecraft ever developed, delivering...

Having a large-scale boreal forest biomass inventory would allow scientists to understand better the carbon cycle and to predict more accurately Earth's future climate. However, obtaining these maps has been wrought with difficulty "“ until now. A new processing algorithm has been developed using stacks of images from the Advanced Synthetic Aperture Radar (ASAR) on ESA's Envisat satellite that allows for the retrieval of boreal forest biomass well beyond the levels that have been...

WASHINGTON, March 1 /PRNewswire-USNewswire/ -- Using data from a NASA radar that flew aboard India's Chandrayaan-1 spacecraft, scientists have detected ice deposits near the moon's north pole. NASA's Mini-SAR instrument, a lightweight, synthetic aperture radar, found more than 40 small craters with water ice. The craters range in size from 1 to 9 miles (2 to 15 km) in diameter. Although the total amount of ice depends on its thickness in each crater, it's estimated there could be at least...

The intense public debate on how rapidly the Himalayan glaciers are retreating highlights the necessity for the constant monitoring of glaciers worldwide by satellites. Since glaciers are among the most reliable indicators of climate change and because they can have a major influence on water availability, knowledge of the recent changes and future behavior is of great interest for climate scientists and governing bodies. A key to assess these changes or to model their future evolution is the...

In response to the disaster in Haiti on Jan. 12, NASA has added a series of science overflights of earthquake faults in Haiti and the Dominican Republic on the island of Hispaniola to a previously scheduled three-week airborne radar campaign to Central America. NASA's Uninhabited Aerial Vehicle Synthetic Aperture Radar, or UAVSAR, left NASA's Dryden Flight Research Center in Edwards, Calif., on Jan. 25 aboard a modified NASA Gulfstream III aircraft. During its trek to Central America, which...

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...
