RICHMOND, BC, Oct. 9, 2014 /CNW/ - MacDonald, Dettwiler and Associates Ltd. ("MDA" or the "Company") (TSX:MDA) and the Institute of Electrical and Electronics Engineers (IEEE) today announced that the first use of a digital processor to reconstruct an image from Seasat, the first civilian spaceborne synthetic aperture radar (SAR) satellite, has been recognized as an IEEE Milestone in Electrical Engineering and Computing. This groundbreaking image, produced in November 1978 by...

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...

QuikScat's Eye On Ocean Winds Lives On After 15 Years
2014-06-20 03:55:48

Rosalie Murphy, NASA's Jet Propulsion Laboratory Today (June 19) marks the 15th anniversary of the launch of NASA's QuikScat, a satellite sent for a three-year mission in 1999 that continues collecting data. Built in less than 12 months, QuikScat has watched ocean wind patterns for 15 years and improved weather forecasting worldwide. Despite a partial instrument failure in 2009, it provides calibration data to international partners. On this anniversary, the mission's team is preparing...

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...

Former JPL Director Bruce C. Murray Dies After A Long Illness At The Age Of 81

NASA's Jet Propulsion Laboratory Murray was at the helm of JPL from 1976 to 1982, during a very busy time for planetary exploration - when the Viking spacecraft landed on Mars, and Voyager 1 and 2 were launched and flew by Jupiter and Saturn. After leaving JPL, Murray was a professor of planetary science and geology at the California Institute of Technology in Pasadena, which manages JPL for NASA. As JPL director, Murray faced a rapidly shrinking budget, along with the rest of NASA....

35-Year-Old Seasat Images Now Available From The Alaska Satellite Facility
2013-07-04 05:12:16

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...

Seasat Blazed The Trail For Many Mission
2013-06-28 05:27:14

April Flowers for redOrbit.com - Your Universe Online Even if they don't last long, history tends to look fondly upon trailblazers. Thirty-five years ago this week, NASA's Jet Propulsion Laboratory (JPL) launched an experimental satellite called Seasat, with the mission to study Earth and its seas. An unexpected malfunction ended the mission after just 106 days, leading some to look on the satellite as a failure. Seasat is still in orbit, however, shining in the night sky at magnitude...

NASA mission managers are assessing options for future operations of the venerable QuikScat satellite following the age-related failure of a mechanism that spins the scatterometer antenna. This spinning antenna had been providing near-real-time ocean- surface wind speed and direction data over 90 percent of the global ocean every day. In recent months, the QuikScat project team has been monitoring a pattern of increasing friction in the bearings that allow the antenna to spin, leading to...

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...
