El Niño: 2014 Looking Like 1997
2014-05-21 03:21:35

Dr. Tony Phillips, Science@NASA [ Watch The Video: ScienceCasts: El Niño – Is 2014 The New 1997? ] Every ten days, the NASA/French Space Agency Jason-2 satellite maps all the world's oceans, monitoring changes in sea surface height, a measure of heat in the upper layers of the water. Because our planet is more than 70% ocean, this information is crucial to global forecasts of weather and climate. Lately, Jason-2 has seen something brewing in the Pacific—and it looks a lot like...

WASHINGTON, May 2, 2014 /PRNewswire-USNewswire/ -- NASA and the French space agency Centre National d'Études Spatiales (CNES) have agreed to jointly build, launch, and operate a spacecraft to conduct the first-ever global survey of Earth's surface water and to map ocean surface height with unprecedented detail. http://photos.prnewswire.com/prnvar/20081007/38461LOGO NASA Administrator Charles Bolden and CNES President Jean-Yves Le Gall signed an agreement Friday at NASA Headquarters in...

La Nada Event In Pacific
2013-09-10 15:37:20

Brett Smith for redOrbit.com - Your Universe Online Based on data from one of NASA’s orbiting satellites, experts at the National Weather Service’s Climate Prediction Center have found near-normal sea-surface height conditions across the equatorial Pacific Ocean, indicative of a so called “La Nada” event. The weather experts added that the condition has persisted for 16 months, since spring 2012 and will continue through the spring of 2014. “Without an El Niño or La Niña...

Smallest Continent Had Biggest Role In Sea Level Drop
2013-08-20 08:53:03

NASA A unique and complex set of circumstances came together over Australia from 2010 to 2011 to cause Earth’s smallest continent to be the biggest contributor to the observed drop in global sea level rise during that time, finds a new study co-authored and co-funded by NASA. In 2011, scientists at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., and the University of Colorado at Boulder reported that between early 2010 and summer 2011, global sea level fell sharply, by about a...

Jason-1 Satellite Decommissioned
2013-07-03 14:48:04

Michael Harper for redOrbit.com - Your Universe Online More than 11 years ago, NASA launched the Jason-1 ocean altimetry satellite into orbit in a joint venture with the Centre National d'Etudes Spatiales (CNES). The satellite would be used to map sea levels, wave height and wind speed from miles above the ocean's surface. Since that time, one successor satellite, the Jason-2, has been sent into space to supplement this information. The Jason-3 is expected to launch in 2015. Two weeks...

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...

Sensors For Seafaring Satellite Shipped By NASA
2013-05-23 15:21:07

NASA's Jet Propulsion Laboratory Three NASA-built instruments that are integral components of the next in a series of U.S./European ocean altimetry satellites have arrived in France for integration with their spacecraft in preparation for a 2015 launch. Jason-3 will extend the two-decade series of satellites that are tracking global sea level changes and enabling more accurate weather, ocean and climate forecasts. The three instruments are a microwave radiometer and two location-finding...

'20 Years Of Progress In Radar Altimetry Symposium' Gains Altitude In Venice
2012-09-24 10:41:43

Scientists have gathered in the 'floating city' this week to talk about radar altimetry — measuring the heights of the global sea surface, freshwater bodies, land and ice using spaceborne sensors. Held every five years, the '20 Years of Progress in Radar Altimetry Symposium' gives participants the opportunity to focus on the challenges overcome to develop our current understanding of Earth´s surface variations observed by altimetry. Radar altimeters record the surface...

NASA has selected Space Exploration Technologies (SpaceX) of Hawthorne, Calif., to launch the National Oceanic and Atmospheric Administration's (NOAA) Jason-3 spacecraft in December 2014 aboard a Falcon 9 v1.0 rocket from Complex 4 at Vandenberg Air Force Base in California. The total value of the Jason-3 launch service is approximately $82 million. This estimated cost includes the task ordered launch service for the Falcon 9 v1.0, plus additional services under other contracts for payload...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
