SUMMARY:NASA to Preview Upcoming Spacewalks
DESCRIPTION:2pm ET\, NASA will discuss the U.S. Spacewalks #100 and #101 to complete solar array installation and power augmentation of the International Space Station during a news conference at 2 p.m. EDT\, Tuesday\, Oct. 20\, from NASA’s Johnson Space Center in Houston. \nNASA participants in the news conference include: \nGaurang Patel\, operations integration manager\, Low Earth Orbit Program\nGarrett Hehn\, spacewalk flight director\, Flight Operations Directorate\nUnited States-based media interested in attending in person must contact the Johnson newsroom no later than 3 p.m.\, Monday\, Oct. 19\, at: jsccommu@mail.nasa.gov. Media joining by phone should request dial-in details by the same deadline. To ask a question\, media must dial in no later than 15 minutes before the start of the news conference. \nThursday\, Oct. 29 \nDuring U.S. spacewalk 100\, NASA astronaut Anil Menon and CSA (Canadian Space Agency) astronaut Joshua Kutryk will exit the station’s Quest airlock to install and deploy an International Space Station Roll-Out Solar Array (IROSA) on the 2A electrical power channel. The solar array will be the seventh IROSA and will provide additional power to support critical station operations\, including its safe and controlled deorbit. \nThursday\, Nov. 5 \nDuring U.S. spacewalk 101\, Menon and Kutryk will install and deploy the eighth and final IROSA on the 3B channel of the space station\, completing the power augmentation upgrades. \nThe final two roll-out solar arrays will complete the space station’s power system augmentation. Together\, the eight roll-out arrays will increase available power by up to 30%\, boosting the station’s electric power generation capacity from 160 kilowatts to approximately 215 kilowatts. \nNASA will share additional coverage details about U.S. spacewalks 100 and 101 closer to each operation on the agency’s live events web page and the space station blog. The spacewalks will be the 285th and 286th conducted in support of space station assembly\, maintenance\, and upgrades. \nTo learn more about International Space Station research\, operations\, and its crews\, visit: \nhttps://www.nasa.gov/station

SUMMARY:9 Years Ago: Cassini Plunged into Saturn's Atmosphere
DESCRIPTION:The Cassini spacecraft deliberately plunged into Saturn’s atmosphere on September 15\, 2017. \nFinal Moments and Impact \nLoss of Signal: The final signal from Cassini was received on Earth at 4:55 a.m. PDT (7:55 a.m. EDT) on September 15\, 2017\, accounting for an 83-minute light-travel delay. \nActual Disintegration: The spacecraft actually entered the upper atmosphere and disintegrated a bit earlier\, around 7:31 a.m. Eastern time (4:31 a.m. Pacific time). \nReason for the Crash: NASA purposefully disposed of the Cassini spacecraft via a controlled fall to prevent any accidental biological contamination of Saturn’s potentially habitable moons\, like Enceladus and Titan.

SUMMARY:NASA Live Coverage of Solar Eclipse
DESCRIPTION:NASA will stream the eclipse live with views across the path and interviews with subject matter experts through a variety of platforms. \nDuring the eclipse\, NASA will conduct experiments in the path of totality. To investigate the dynamics of the Sun’s corona\, a NASA-funded science team will chase the Moon’s shadow with a WB-57 high-altitude research aircraft. The NASA-supported Nationwide Eclipse Ballooning Project is sending students from several U.S. universities to Iceland and Spain to launch scientific balloons before\, during\, and after the eclipse to research how the temporary darkening of our skies during the eclipse affects Earth’s atmosphere. \nNASA’s eclipse coverage is as follows (all times Eastern): \nWednesday\, Aug. 12 \n\n1:15 p.m.: Eclipse broadcast begins\n1:45 p.m.: Totality begins in Iceland\n2:28 p.m.: Totality begins in Spain\n\nNASA photography coverage\nPhotos of the eclipse\, dependent on visibility\, will be available shortly after the eclipse. View images on the agency’s Flickr account.

SUMMARY:NASA Astronaut Chris Williams Post-ISS Mission Debrief
DESCRIPTION:2:45 pm EDT from Johnson Space Center\, NASA astronaut Chris Williams will recap his recent eight-month mission aboard the International Space Station. Williams returned to Earth on July 26\, after logging 241 days as an Expedition 73/74 flight engineer during his first spaceflight. He returned along with Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev\, completing 3\,856 orbits of the Earth over the course of their more than 102-million-mile journey. They also saw the arrival of six visiting spacecraft and the departure of eight. \nDuring his mission\, Williams supported a wide range of scientific investigations and technology demonstrations. He helped advance research for new cancer treatments and improved in-space manufacturing of materials used in high-performance computers and electronics. Williams also completed two spacewalks to prep for space station power system upgrades and to replace a faulty joint on the Canadarm2 robotic arm. The crew’s work aboard the space station helps improve life on Earth and prepare for future human missions to the Moon and Mars. \n
