On April 12, 2013, the Landsat Data Continuity Mission (LDCM) reached its final altitude of 705 kilometers (438 miles). One week later, the satellite’s natural-color imager scanned a swath of land 185-kilometers wide and 9,000 kilometers long (120 by 6,000 miles)—an unusual, unbroken distance considering 70 percent of Earth is covered with water.
