Twilight in Antarctica, February 24, 2000. Nearly 15 times every 24 hours, the Terra spacecraft, traveling southward, crosses from day into night at high southern latitudes. This true-color image was taken by the most steeply forward looking camera of the Multi-angle Imaging SpectroRadiometer (MISR) instrument on board Terra. The Ross Ice Shelf and Transantarctic Mountains are illuminated by low Sun.

MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Science Mission Directorate, Washington, D.C. The Terra spacecraft is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. The MISR data were obtained from the NASA Langley Research Center Atmospheric Science Data Center in Hampton, VA.
