NASA plane stains another weird rectangular iceberg
Just when the excitement was starting to fade from NASA's discovery of what appeared to be a perfectly square or square or rectangular iceberg or parallelogram (none entirely adequate), the space agency launched a second set of images showing a second box or berg in the form of cake not too far from the first. The new photos also show one of the world's largest iceberg in the background, indicating that they may have been born by the same ice shelf. Or was it extraterrestrial?
"Actually, I was more interested in capturing the A68 iceberg we were about to fly over, but I thought that this rectangular iceberg was visually interesting and quite photogenic, so at least I took a couple of photos."
This time, NASA tried to avoid any conspiracy theory by allowing the photographer of the icebergs, the support scientist Jeremy Harbeck of Operation IceBridge, to comment on what the crew saw as they flew over the northern Antarctic Peninsula on October 16 as they watched Larsen's ice shelves A, B and C to detect changes in glaciers that would show the impact of climate change. While these tabular icebergs (actually they could be cubes, since only 10 percent of their mass is on water) are rare (two together are extremely rare), they are not unknown, says Harbeck.
"I thought it was very interesting, I often see icebergs with relatively straight edges, but I have not really seen one before with two corners at right angles like this one."

Nor anyone else, judging by the amount of attention received by the images of the first tabular icebergs on the Internet. As Harbeck pointed out, the iceberg that really interested him was A68 in the background. That broke from the Larsen C ice shelf in July 2017, reducing its size by 12 percent. Its surface has been compared to a Delaware or two Luxembourgs, depending on which side of the Atlantic it lives, and it weighed a trillion tons. It is still close to that size, but that will change as it moves away, melts and lifts the coastal waters around the world as it continues its planned meandering path towards South Georgia and the South Sandwich Islands in the South Atlantic Ocean .
Of course, large is not as interesting as perfectly rectangular, so the small bergs (possibly a mile wide) but rectangular draw attention. Since Antarctic scientists rarely receive this kind of publicity, Harbeck is no doubt looking for more unusual ice as this phase of Operation IceBridge continues through November 18.

For those who still refuse to believe in NASA, why do extraterrestrials spend time cutting ice in geometric shapes? Boredom? Try new laser weapons? Was the video game player eliminated?
