On Thursday, Sept. 1, U.S. astronauts Jeff Williams and Kate Rubins will conduct the station’s 195th American spacewalk. As part of their activities, the pair will install the first of several enhanced high-definition television cameras that will monitor activities outside the station, including the comings and goings of visiting cargo and crew vehicles
Working on the station’s backbone, or truss, Williams and Rubins will retract a thermal radiator that is part of the station’s cooling system.
As was the case for their first spacewalk together on Aug. 19, Williams will be designated as extravehicular crew member 1 (EV1), wearing a spacesuit with a red stripe, while Rubins will be EV2, wearing a suit with no stripes.
Coverage of the spacewalk begins at 6:30 a.m. EDT on Thursday, Sept. 1; with the spacewalk scheduled to begin at 8:05 a.m. EDT. Stream live online HERE.

The Running Chicken Nebula.

These three bright nebulae are often featured in telescopic tours of the constellation Sagittariusand the crowded starfields of the central Milky Way.
In fact, 18th century cosmic touristCharles Messier cataloged two of them; M8, the large nebula left of center, and colorful M20 near the bottom of the frame. The third, NGC 6559, is right of M8, separated from the larger nebula by dark dust lanes. All three are stellar nurseries about five thousand light-years or so distant. The expansive M8, over a hundred light-years across, is also known as the Lagoon Nebula. M20’s popular moniker is the Trifid.
In the composite image, narrowband data records ionized hydrogen, oxygen, and sulfur atoms radiating at visible wavelengths. The mapping of colors and range of brightness used to compose this cosmic still life were inspired by Van Gogh’s famous Sunflowers.
Just right of the Trifid one of Messier’s open star clusters,M21, is also included on the telescopic canvas.

Time And Space
The Department of Awesome Natural Phenomena has features amazing auroras before, but never an aurora on another planet! This extraordinary sight, brought to us by the NASA/ESA Hubble Space Telescope, is an incredibly colossal aurora taking place on Jupiter:
“At the gas giant’s north pole, the most powerful and luminous northern lights in the solar system shimmer and glow in an endless geomagnetic storm that’s larger than our entire planet.”
That’s right, Jupiter itself is already so awesomely huge that its auroras are larger than the planet Earth.
Watch this time-lapse video of the Jupiter auroras and then visit the Hubble website to learn more about this amazing phenomena.
