Record-Low Sea Ice
On Feb. 13, 2017, the combined Arctic and Antarctic sea-ice numbers were at their lowest point since satellites began to continuously measure sea ice in 1979.
NASA's CYGNSS Constellation Enters Science Operations Phase
NASA's Cyclone Global Navigation Satellite System (CYGNSS), a constellation of eight microsatellites that will take detailed measurement of wind speeds inside hurricanes, successfully completed the development and on-orbit commissioning phases of its mission and moved into the science operations phase.
Satellite Data Reveal Effects of Aerosols
Earth's atmosphere is dusted with tiny particles known as aerosols, which include windblown ash, sea salt, pollution, and other natural and human-produced materials. Aerosols can absorb or scatter sunlight, affecting how much light reflects back into space or stays trapped in the atmosphere.
Utah's Snow-Covered Bryce Canyon
Utah's Bryce Canyon is not the deepest canyon in the United States; its largest amphitheater of naturally eroded rock drops 240 meters.

But photographers who visit Bryce Canyon National Park typically aren't looking for dizzying heights and depth; they're often trying to capture images of the delicate spires called hoodoos that rise from the canyon.
˜Brain' of Space Launch System RS-25 Engine Passes Critical Test
