Photos released on Friday from NASA's Operation Icebridge show with a stunning clarity that the huge rift in the Larsen C ice shelf is getting closer to causing a section of ice the size of Delaware to break off.
Scientists have been monitoring a massive crack in one of Antarctica's largest ice shelves for some time. In the last five months alone, the fracture has grown an extra 22 kilometers, and it's only a matter of time before it breaks free.
The satellite images not only capture the crack's length, but also the "texture" of the ice shelf with smooth ice depicted as blue and rougher areas — like the rift and open water — as orange.
