Month: February 2017

Frequent cloud cover in the southern Atlantic Ocean often obscures satellite images of South Georgia and the South Sandwich Islands. But occasionally the clouds give way. On September 14, 2016, the Operational Land Imager (OLI) on Landsat 8 captured natural-color images of South Georgia Island, where several glaciers are in retreat. via NASA http://ift.tt/2m3yN2e

These images of the sun were captured at the same time on January 29, 2017 by the six channels on the Solar Ultraviolet Imager or SUVI instrument aboard NOAA’s GOES-16 satellite. Data from SUVI will provide an estimation of coronal plasma temperatures and emission measurements which are important to space weather forecasting. via NASA http://ift.tt/2lOkQTJ

A NASA Black Brant IX sounding rocket soars skyward into an aurora over Alaska following a 5:13 a.m. EST, Feb. 22, 2017 launch from the Poker Flat Research Range in Alaska. The rocket carried an Ionospheric Structuring: In Situ and Groundbased Low Altitude StudieS (ISINGLASS) instrumented payload examining the structure of an aurora. via NASA http://ift.tt/2lp4hz6

When viewed from a distance with the sun directly behind Cassini, the larger, brighter craters really stand out on moons like Dione. via NASA http://ift.tt/2kHYR3n

A SpaceX Falcon 9 rocket lifts off from Launch Complex 39A at NASA's Kennedy Space Center in Florida. This is the company's 10th commercial resupply services mission to the International Space Station. Liftoff was at 9:39 a.m. EST from the historic launch site now operated by SpaceX under a property agreement with NASA. via NASA http://ift.tt/2kNCo03

NASA provider SpaceX's Falcon 9 rocket and Dragon spacecraft are vertical at Launch Complex 39A at NASA’s Kennedy Space Center in Florida. Liftoff of SpaceX's tenth Commercial Resupply Services cargo mission to the International Space Station is scheduled for 10:01 a.m. EST on Saturday, Feb. 18, 2017. via NASA http://ift.tt/2lr9OFB

Pine Island Glacier has shed another block of ice into Antarctic waters. The loss was tiny compared to the icebergs that broke off in 2014 and 2015, but the event is further evidence of the ice shelf’s fragility. via NASA http://ift.tt/2lhOlz6

Expedition 50 Flight Engineer Thomas Pesquet of the European Space Agency shared this photograph from the International Space Station on Feb. 14, 2017, writing, "Venice, city of gondoliers and the lovers they carry along the canals. Happy Valentine's Day!" via NASA http://ift.tt/2kti7fZ

When seen up close, the F ring of Saturn resolves into multiple dusty strands. This Cassini view shows three bright strands and a very faint fourth strand off to the right. via NASA http://ift.tt/2lc53zv

The Andromeda constellation is one of the 88 modern constellations and should not be confused with our neighboring Andromeda Galaxy. via NASA http://ift.tt/2kcRMCB

Jeanette Scissum joined NASA’s Marshall Space Flight Center in 1964 after earning bachelor's and master's degrees in mathematics from Alabama A&M University. Scissum published a NASA report in 1967, “Survey of Solar Cycle Prediction Models,” which put forward techniques for improved forecasting of the sunspot cycle. via NASA http://ift.tt/2lofO2M

A sunrise photo of Edwards Air Force Base’s Rogers Dry Lake was taken after heavy rainfall in southern California. NASA’s Armstrong Flight Research Center is seen in the foreground. via NASA http://ift.tt/2kmG89u
