MEDIA ADVISORY M17-091 NASA Television to Air Six-Hour Spacewalk at International Space Station

Two Russian cosmonauts will venture outside the International Space Station Thursday, Aug. 17, to deploy several nanosatellites, collect research samples and perform structural maintenance. Coverage of the spacewalk will begin at 10 a.m. EDT on NASA Television and the agency’s website.

Expedition 52 Commander Fyodor Yurchikhin and Flight Engineer Sergey Ryazanskiy, of the Russian space agency Roscosmos, will don their spacesuits and exit the station's Pirs airlock at approximately 10:45 a.m.

Ryazanskiy will begin the schedule of extravehicular activities with the manual deployment of five nanosatellites from a ladder outside the airlock. The satellites, each of which has a mass of about 11 pounds, have a variety of purposes.

One of the satellites, with casings made using 3-D printing technology, will test the effect of the low-Earth-orbit environment on the composition of 3-D printed materials. Another satellite contains recorded greetings to the people of Earth in 11 languages. A third satellite commemorates the 60th anniversary of the Sputnik 1 launch and the 160th anniversary of the birth of Russian scientist Konstantin Tsiolkovsky.

The spacewalkers also will collect residue samples from various locations outside the Russian segment of the station and install handrails and struts to facilitate future excursions.

Yurchikhin will be designated extravehicular crew member 1 (EV1) for this spacewalk, the ninth of his career. Ryazanskiy, embarking on his fourth spacewalk, will be extravehicular crew member 2 (EV2). Both will wear Russian Orlan spacesuits bearing blue stripes. The spacewalk will be the 202nd in support of space station assembly and maintenance and the seventh spacewalk this year.

MEDIA ADVISORY M17-092 NASA Announces Television Coverage for Aug. 21 Solar Eclipse

On Monday, Aug. 21, all of North America will be treated to an eclipse of the Sun, and NASA Television will carry it live from coast to coast from unique vantage points on the ground and from aircraft and spacecraft, including the International Space Station. Coverage will be featured during the live four-hour broadcast Eclipse Across America: Through the Eyes of NASA.

Programming begins at noon EDT with a preview show hosted from Charleston, South Carolina. The main show begins at 1 p.m. and will cover the path of totality the eclipse will take across the United States, from Oregon to South Carolina. The program will feature views from NASA research aircraft, high-altitude balloons, satellites and specially-modified telescopes. It also will include live reports from Charleston, as well as from Salem, Oregon; Idaho Falls, Idaho; Beatrice, Nebraska; Jefferson City, Missouri; Carbondale, Illinois; Hopkinsville, Kentucky; and Clarksville, Tennessee.

The Toshiba Vision screen in New York’s Times Square will broadcast the program live in its entirety to give the public a big-screen view of the eclipse. Viewers in Times Square can listen to NASA coverage while observing it on the big screen by downloading the NASA app or going to https://www.nasa.gov/eclipselive.
