India launches European 'artificial eclipse' satellites
Raw StoryIndia on Thursday successfully launched into space a pair of European satellites that will create artificial solar eclipses to help scientists catch a rare glimpse of the Sun's mysterious atmosphere. The launch, originally scheduled for Wednesday but delayed by a technical fault, was for the European Space Agency's "Project for On-Board Autonomy 3" mission, part of a series of "in-orbit missions to test out new technologies". The mission, at a cost of 200 million euros, creates artificial total solar eclipses by positioning two satellites 150 meters apart from each other. "For six hours at a time, it will be able to see the Sun's faint atmosphere, the corona, in the hard-to-observe region between the Sun's edge and 1.4 million kilometers from its surface," the European Space Agency said in a pre-launch analysis.
