Latest Synthetic aperture radar Stories
Scientists are crediting satellite imagery with helping to predict where volcanic eruptions could strike. It is well known that earthquakes can stress Earthâ€™s crust and trigger subsequent quakes, but there has been no proof of this for volcanoes until now.
The magnitude 7.0 earthquake that caused more than 200,000 casualties and devastated Haiti's economy in January resulted not from the Enriquillo fault, as previously believed, but from slip on multiple faults.
Devastating around a third of the country, it is estimated that the floods in Pakistan have affected up to 20 million people.
New NASA airborne radar images of Southern California near the U.S.-Mexico border show Earth's surface is continuing to deform.
An award-winning new website is using realtime imagery from ESA's Envisat satellite to provide a wealth of information on sea ice to aid safe passage through the treacherous waters of the Antarctic.
On Earth, lake levels rise and fall with the seasons and with longer-term climate changes, as precipitation, evaporation, and runoff add and remove liquid.
This Envisat radar image acquired over the Gulf of Mexico on June 22, 2010 shows that the oil spill (outlined in white) has radiated all over the Gulf of Mexico basin and is also continuing to feed into the Loop Current (red arrow).
Scientists monitoring the US oil spill with ESAâ€™s Envisat radar satellite say that it has entered the Loop Current, a powerful conveyor belt that flows clockwise around the Gulf of Mexico towards Florida.
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 ESAâ€™s Envisat radar data.
ESAâ€™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.
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...
