They are unpublished photographs provided by NASA, those of the iceberg A68, that separated of Larsen C, in the Antarctic Peninsula, the images were captured during the mission of name IceBridge.
The new aerial images were released and show a gigantic iceberg of 5,800 square kilometers, also known as the A68. This huge block of floating ice broke out this year last July, at which time one of the largest disintegrations of the Larsen C platform occurred, which stretches along the eastern coast of the Antarctic Peninsula. After a long time of monitoring, the block of ice finally separated, moving now by the sea, according to the ABC publication.
With a significant increase in sunlight at this time of year, the US space agency NASA has conducted several reconnaissance flights that are part of the IceBridge mission, which in turn uses the planet’s polar ice Earth, in order to better understand the connections between the polar regions and the climate system, even at the global level. This mission also aims to study the annual changes in the thickness of the sea ice as well as the ice sheets.
The photos that were recently published by NASA Twitter, have confirmed and sediment all observations already made. There is a huge gap that was opened between the shore bounded by Larsen C and the iceberg A68. As we can see from the images provided by the agency.
Operation IceBridge is ready to fly! The weather looks good locally in Ushuaia and in Antarctica, so OIB will attempt the gravity mission over the Larsen C ice shelf. Photo by NASA/John Sonntag. pic.twitter.com/qUnEvQKwnZ

Antarctic ice sheets are huge floating ice sheets that surround the continent, so it is normal and surprising that fragments of ice are released, forming small icebergs. However, the dimensions of the A68 raise some concerns as the water it contains is sufficient to raise sea level by about 3 millimeters, according to information provided by Gizmodo.
