NASA's high flying observation instruments are good at peering deep into space, but the agency also spends lots of time staring at our own planet. NASA has been working hard on the work of the past decades and is developing models and recording observations showing what is happening to the Earth, and now scientists are warning that a huge lump of ice is releasing from Antarctica.
A colossal cracking of the Brown Ice Shelf in Antarctica will soon split an ice cube twice the size of New York City, NASA says, and the increasingly unpredictable nature of the ice can threaten the research stations that have been operating in that part of Antarctica for decades.  In pictures taken by NASA's Landsat satellites, we can see cracks stretching for large shelf distances. The big "Halloween crack", as it is called, has grown since 201
An investigation decision run by the British Antarctic investigation is immediately affected during this dramatic event. It is not far from the two growing cracks, and when the ice breaks, no one knows how it will affect the ice stability that leads to the actual settlement. NASA notes that for some years the station has had to leave because of the threat of unstable ice.
The clump that is being released spans 660 square kilometers. It's big of everyone's standards, and it will be the biggest piece of ice to break free from Brown Ice Shelf, since scientists began to keep track of such things. It can't hold a light to much larger icebergs that have gone loose in other areas of Antarctica, but it's yet another reminder that we are losing this ice faster than it can regenerate.
