    Like people, plants have circadian rhythms 🌱💤 and are less active at night. ‘s "space botanist" instrument, ECOSTRESS, aboard the , can see plants "waking up" 🌞 from space, helping scientists gain new insight into how plants behave:

    The image shows plants "waking up" near Lake Superior. Red areas began to wake up at around 7 a.m. local time; green areas awoke around 8 a.m.; and blue areas, at about 9 a.m. The data was acquired by ECOSTRESS during the summer season. Credit: NASA / JPL-Caltech

    Since its launch January 31, 2015, SMAP has measured both soil moisture and sea surface salinity. Each dataset helps scientists study Earth’s 🌏 many interconnected systems and assists in planning for natural phenomena like droughts or floods:

Dry areas appear yellow/orange, such as the Sahara Desert, western Australia and the western U.S. Wet areas appear blue, representing the impacts of localized storms. White areas indicate snow, ice or frozen ground. Credit: NASA/JPL
