Rosalie Murphy, JPL Earth Science and Technology Directorate The ocean covers 71 percent of Earth's surface and affects weather over the entire globe. Hurricanes and storms that begin far out over the ocean affect people on land and interfere with shipping at sea. And the ocean stores carbon and heat, which are transported from the ocean to the air and back, allowing for photosynthesis and affecting Earth's climate. To understand all these processes, scientists need information about winds...

Historic Earth Images From NASA Still Hold Research Value

Carol Rasmussen, NASA NASA's Seasat satellite became history long ago, but it left a legacy of images of Earth's ocean, volcanoes, forests and other features that were made by the first synthetic aperture radar ever mounted on a satellite. Potential research uses for the recently released 35-year-old images are outlined in a paper published in the journal Eos today, March 18. Seasat, which was managed by NASA's Jet Propulsion Laboratory in Pasadena, Calif., was the first satellite...

Lee Rannals for redOrbit.com - Your Universe Online The Alaska Satellite Facility (ASF) Distributed Active Archive Center (DAAC) has released newly processed digital images from NASA's Seasat satellite that were taken 35 years ago. The Seasat satellite was the first mission dedicated to oceanographic research. The satellite supported the first nonmilitary orbital synthetic aperture radar ever deployed. The newly released imagery commemorated the satellite's 35th launch anniversary on...

Small satellite manufacturer Surrey Satellite Technology Limited (SSTL) has today announced completion of the development phase of its new low-cost Synthetic Aperture Radar (SAR) satellite system. Called NovaSAR-S, the system offers customers coverage of any spot on Earth in all conditions — seeing through cloud cover across both day and night. The 400-kg NovaSAR-S design combines SSTL´s flight-proven SSTL-300 platform with an innovative S-band SAR payload, developed in...

NASA will 'break the ice' on a pair of new airborne radars that can help monitor climate change when a team of scientists embarks this week on a two-month expedition to the vast, frigid terrain of Greenland and Iceland. Scientists from NASA's Jet Propulsion Laboratory, Pasadena, Calif., and Dryden Flight Research Center, Edwards, Calif., will depart Dryden Friday, May 1, on a modified NASA Gulfstream III aircraft. In a pod beneath the aircraft's fuselage will be two JPL-developed radars that...

ESA's Mars Express radar sounder, MARSIS, has looked beneath the Martian surface and opened up the third dimension for planetary exploration. The technique's success is prompting scientists to think of all the other places in the Solar System where they would like to use radar sounders. No matter how accurate a camera is, it can only map a planet's surface. To retrieve information about the underground realm, planetary scientists in the past would have thought it necessary to land on the...

NASA's Mars Reconnaissance Orbiter has extended the long-armed antenna of its radar, preparing the instrument to begin probing for underground layers of Mars. The orbiter's Shallow Subsurface Radar, provided by the Italian Space Agency, will search to depths of about one kilometer (six-tenths of a mile) to find and map layers of ice, rock and, if present, liquid water. The radar's antenna had remained safely folded and tucked away throughout the flight to Mars from Aug. 12, 2005, to March...

A radar altimeter measures altitude above the terrain beneath an aircraft as opposed to a barometric altimeter which provides the distance above a pre-determined datum, usually sea level. Radar is the underpinning principle of the system. Radio waves that are reflected back from the ground are timed in order to calculate speed, distance, and time which are related to the each other and can be used to calculate the distance from one point to another. Lloyd Espenschied invented the radar...
