New Date Set For Metop Launch
2012-06-30 10:06:01

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency (ESA) announced a new launch date for its latest edition to its polar-orbiting satellite group, Metop. The new launch date is set for Metop-B satellite on September 19, 2012, when it will be lifting off from the Baikonur Cosmodrome. ESA said the satellite is being stored in a controlled environment in the Starsem facilities in Baikonur, and it will be subject to a set of tests and activities before its...

CryoSat Maps The Ocean Floor
2012-05-29 03:11:36

CryoSat was launched in 2010 to measure sea-ice thickness in the Arctic, but data from the Earth-observing satellite have also been exploited for other studies. High-resolution mapping of the topography of the ocean floor is now being added to the ice mission´s repertoire. The main objective of the polar-orbiting CryoSat is to measure the thickness of polar sea ice and monitor changes in the ice sheets that blanket Greenland and Antarctica. But the satellite´s radar altimeter...

Repeating La Niña Hitting Its Peak: NASA
2012-01-21 04:27:40

La Niña, "the diva of drought," is peaking, increasing the odds that the Pacific Northwest will have more stormy weather this winter and spring, while the southwestern and southern United States will be dry. Sea surface height data from NASA's Jason-1 and -2 satellites show that the milder repeat of last year's strong La Niña has recently intensified, as seen in the latest Jason-2 image of the Pacific Ocean shown above. The image is based on the average of...

Image 1 - CryoSat Rides New Waves
2011-12-23 04:10:38

ESA´s CryoSat mission has been gathering detailed information on the thickness of Earth´s ice since its launch in 2010. Through international collaboration, this state-of-the-art mission is soon to be used to monitor conditions at sea for marine forecasting. CryoSat was built to measure tiny variations in the thickness of Earth´s ice. As a result, the mission is providing scientists with the data they need to help improve our understanding of the relationship between ice,...

Image 1 - Japanese Devastation The Result Of Merging Waves
2011-12-06 09:57:05

[ Watch the Video ] Researchers from NASA and Ohio State University have discovered that the deadly tsunami generated from the March 2011 Tohoku-Oki earthquake that devastated northeastern Japan resulted from merging waves, causing the killer tsunami to double in intensity over ocean ridges, and then amplifying its power upon landfall. Data taken from NASA and European radar satellites captured at least two wave fronts during the events that day. The fronts merged to form a single, more...

  An Update from NASA's Sea Level Sentinels: Like mercury in a thermometer, ocean waters expand as they warm. This, along with melting glaciers and ice sheets in Greenland and Antarctica, drives sea levels higher over the long term. For the past 18 years, the U.S./French Jason-1, Jason-2 and Topex/Poseidon spacecraft have been monitoring the gradual rise of the world's ocean in response to global warming. While the rise of the global ocean has been remarkably steady for most of...

New NASA satellite data indicate the current La Niña event in the eastern Pacific has remained strong during November and December 2010. A new Ocean Surface Topography Mission (OSTM)/Jason-2 satellite image of the Pacific Ocean that averaged 10 days of data was just released from NASA. The image, centered on Dec. 26, 2010, was created at NASA's Jet Propulsion Laboratory (JPL), Pasadena, Calif. "The solid record of La Niña strength only goes back about...

The tropical Pacific Ocean has transitioned from last winter's El Niño conditions to a cool La Niña, as shown by new data about sea surface heights, collected by the U.S-French Ocean Surface Topography Mission (OSTM)/Jason-2 oceanography satellite. This OSTM/Jason-2 image of the Pacific Ocean is based on the average of 10 days of data centered on Sept. 3, 2010. A new image depicts places where the Pacific sea surface height is higher (warmer) than...

The latest image of Pacific Ocean sea surface heights from the NASA/European Ocean Surface Topography Mission/Jason-2 oceanography satellite, dated June 11, 2010, shows that the tropical Pacific has switched from warm (red) to cold (blue) during the last few months. The blue area in the center of the image depicts the recent appearance of cold water hugging the equator, which the satellite measures as a region of lower-than-normal sea level. Remnants of the El Niño warm...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
