First quality photograph of the Antarctic glacier
In early July, a rift formed on the ice shelf of Larten C in Antarctica caused the third largest glacier ever recorded to disengage from the mainland.
The ice block, called the A-68 glacier, may circulate for years in the open sea, and is amazing in size: about the size of Delaware, a mass of material like. Five and a half Everest, and enough to fill Lake Erie-more than twice as much.
Since it is mid-winter in Antarctica, the scientists were struggling to get good optical images of the iceberg. So far, they have relied on polar satellites like Sentinel-1, which uses radar to see through thick cloud cover.
However, a few days of clean weather at the end of July allowed Deimos-1 and Deimos-2, a pair of team satellites-a clear, visible view of the eastern Antarctic Peninsula.
(The satellites work together in space when one takes a large area and the other takes a higher resolution from the satellite)
