Fallow farmland is the main source of human-caused dust storms in California’s Central Valley region, according to a new study using data from NASA and others. From 2008-2022, 88% of major human-caused dust events were associated with fallow land.

This is near Vancouver Island in British Columbia, Canada. And see that blue glow? That’s a herring spawn! Every spring, thousands of Pacific herring congregate in shallow, vegetated coastal areas around this area to spawn, like in this #Landsat 8 image from April 27.

Landsat satellites captured imagery of active fires in north-central Saskatchewan, described by the Saskatchewan Public Safety Agency as the “busiest, most active fire level” this early in the season. Future #Landsat data will help assess landscape impacts.

Landsat could use your support. The mission's 50+ year data continuity is at risk. If you believe contacting elected representatives does anything, now would be a good time to apply pressure. 🛰️📡

#OTD in 1984, #Landsat 5 was launched into space. Far exceeding its three-year design life, Landsat 5 set a #GuinnessWorldRecord for the “Longest-operating #EarthObservation satellite.” Its longevity ensured a continuous stream of data that kept the Landsat archive intact. 🛰️🌎

#DidYouKnow Landsat 8 was the first Landsat mission to use lunar calibration? 🌕 Every month, the satellite pivots to point at the moon and scans the distant lunar surface multiple times to ensure that the Operational Land Imager (OLI) is detecting light consistently.
