Grace Satellites Launched to Weigh Water on Earth
US and Germany have joined hands to launch a pair of satellites that will replace a pair that was already in space but had stopped working. They will do the same job of monitoring tiny variations in the gravity pull caused due to movements of mass and circle the globe. The satellites were launched on Tuesday on a SpaceX rocket from the Vandenberg Air Force in California, US.
It will take some time for the satellites to start gathering data but once they start they would be able to identify the signal of land swelling after constant rain, or ice draining from poles when they melt because of warmer climates. What the Grace concept is brilliant at sensing is the big changes that occur in the hydrological cycle. These could, for example, be major movements of water from the ocean to the land during precipitation events.
Professor Helen Fricker from the Scripps Institution of Oceanography said, “With the launch of Grace-FO, we can now continue to detect changes in the ice mass, to determine the extent to which ice is being lost, and find out if there has been any acceleration.”Disclaimer:We do not allow users to post content which is copyright and We take strict actions against the users who post infringement content on our website.Although we do not host any content, users post embed videos from youtube, facebook, Dailymotion and Vimeo and are moderated before posting but we still take strict action against the copyright videos posted.If you are an official representative of any company whose videos are posted illegally on our website or you think some video infringe the copyright then you can simply send an email to firstname.lastname@example.org
