DARMSTADT, GERMANY – Europe on April 3 launched the first satellite of its multibillion-dollar Copernicus Earth observation project that will supply valuable images in the event of natural disasters or even a plane crash.
The Sentinel-1a satellite, which blasted off into Earth’s orbit from Europe’s spaceport in French Guiana, will be used to monitor sea ice, oil spills and land use, as well as respond to emergencies such as floods and earthquakes.
The satellite, which carries a 12-meter-long radar antenna and has two 10 meter-long solar panels, is now orbiting the planet at 693 km above the Earth.
The Copernicus project, for which the EU and the European Space Agency have committed funding of around $11.5 billion until 2020, is described by the agency as the most ambitious earth observation program to date.
Copernicus is designed to supply data that can help policymakers develop environmental legislation or react to emergencies such as natural disasters or humanitarian crises.
“The Sentinels will keep a watchful eye on our planet,” Thomas Reiter, ESA director of human spaceflight and operations and head of the European Space Agency’s satellite control center ESOC, said at the launch event in the German city of Darmstadt near Frankfurt.
The launch of the Copernicus project became especially urgent after Europe lost contact with its Earth observation satellite Envisat in 2012 after 10 years.
“The big step forward is that we can now cover every place on Earth every three to six days,” said Volker Liebig, director of the European Space Agency’s Earth Observation program. “This used to take much longer with Envisat. If you want to use images for disaster management support or to find a plane, then you want the images to be as fresh as possible.”
But he cautioned you would first need to know roughly where a plane had crashed, which is not the case with the missing Malaysian Airlines jet.
Chris Reynolds, director of the Irish Coast Guard in Dublin, said authorities needed more satellite images and data delivered as quickly as possible to catch “the bad guys,” such as people who purposely dump oil from their ships into the sea. “At the moment, it’s very difficult to find out who has the data and to know what level of trust you can place in it,” he said.
Copernicus also offers new business opportunities.
Images can be downloaded free of charge, meaning companies can then use them to help deliver data to farmers on soil moisture or pest infestation, help oil companies decide where to drill new wells or make it easier for insurers to assess the risk of costly floods and fires.
Sentinel-1a, which will operate in tandem with a second satellite to be launched next year, Sentinel-1b, has high-tech instruments that will allow it to record radar images of Earth’s surface, even when the skies are cloudy or dark. As part of the Copernicus program, there will be 17 launches over the next decade.
Copernicus is one of the EU’s two flagship space programs along with satellite-navigation initiative Galileo, which is meant to rival the dominant U.S. Global Positioning System, Russia’s GLONASS and China’s new Beidou system.
