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. http://www.nasa.gov/sites/default/files/thumbnails/image/32945170225_58129f00dc_o.jpg
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. http://www.nasa.gov/sites/default/files/thumbnails/image/32993070285_ab8a4b50bd_o.jpg
When viewed from a distance with the sun directly behind Cassini, the larger, brighter craters really stand out on moons like Dione. http://www.nasa.gov/sites/default/files/thumbnails/image/pia20521-1041.jpg
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. http://www.nasa.gov/sites/default/files/thumbnails/image/zap10018.jpg
On Feb. 22, engineers successfully installed ESA’s European Service Module Propulsion Qualification Module (PQM) at NASA’s White Sands Test Facility in New Mexico that was delivered by Airbus – ESA’s prime contractor for the Service Module. The module will be equipped with a total of 21 engines to support NASA’s Orion spacecraft. http://www.nasa.gov/sites/default/files/thumbnails/image/p1010141.jpg
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. http://www.nasa.gov/sites/default/files/thumbnails/image/suvi_horz2.png
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. http://www.nasa.gov/sites/default/files/thumbnails/image/neumayer_oli_2016258_lrg.jpg

In this March 29, 1929 photograph, Pearl I. Young is working in the Langley Memorial Aeronautical Laboratory's Flight Instrumentation Facility (Building 1202). Young was the first woman hired as a technical employee, a physicist at the National Advisory Committee for Aeronautics and the second female physicist working for the federal government. http://www.nasa.gov/sites/default/files/thumbnails/image/l-03247.jpg
UGC 12591's classification straddles somewhere between a lenticular and a spiral galaxy. It lies just under 400 million light-years from us in the Pisces–Perseus Supercluster. http://www.nasa.gov/sites/default/files/thumbnails/image/potw1709a.jpg
