Near the western tip of the Mojave Desert and a few miles west of NASA’s
Armstrong Flight Research Center, fields of poppies colored the landscape a bright
orange this spring. On April 14, 2020, the Operational Land Imager (OLI) on the
Landsat 8 satellite acquired these images of vast blooms in the Antelope Valley
California Poppy Reserve. These images were acquired when poppy flowers in the
valley were thought to be at or near their peak.
The flowers bloomed after Southern California received significant rainfall in
March and April 2020. This spring, Lancaster received around 10.5 inches (27
centimeters) of rain—almost 4 inches (10 centimeters) above normal. The extra
rain may cause the poppies to stick around longer than usual and result in an
above-average wildflower year. Park officials called this bloom an “unexpected”
surprise due to the late season rains.
While many parks have restricted visitor access to the park during the COVID-19
quarantine, people can view the flowers through online livestreams,

parks.ca.gov/live/poppyreserve. Depending on the day or even hour, the orange
patches may change in appearance. The poppies open their petals during sunny
periods, appearing like a large blanket over the landscape. The flowers tend to
close during windy, cold periods. While the orange poppies are easy to spot in
satellite imagery, the fields also contain cream cups, forget-me-nots, purple bush
lupines, and yellow goldfields (a relative of the sunflower).
