New View of the “City Under the Ice”

In April 2024, NASA scientist Chad Greene flew aboard a Gulfstream III with a team of engineers, monitoring a radar instrument as it probed the Greenland Ice Sheet below. Flying about 150 miles east from Pituffik Space Base in northern Greenland, Greene snapped this photo from the aircraft’s window showing the vast, barren expanse of the ice sheet’s surface. That’s when the radar unexpectedly detected something buried within the ice.
