ALT A low sun begins to set behind NOAA’s South Pole Atmospheric Research Observatory. The sunset will be the only one for the year.
ALT The sun sets behind the polar plateau, the ice sheet that covers Antarctica and which the South Pole Station sits on top of.
ALT A research team prepares to launch a scientific balloon in a snow-covered landscape at twilight. The team members are bundled in cold-weather gear, holding the large, white balloon next to a well-lit, industrial-looking building partially covered in snow and ice. The sky above is a clear, pale blue, suggesting very cold temperatures.
