	May 22, 2017  MEDIA ADVISORY M17-059 NASA to Discuss First Science Results from Juno Mission to Jupiter This illustration depicts NASA's Juno spacecraft approaching Jupiter. Credits: NASA Scientists from NASA's Juno mission to Jupiter will discuss their first in-depth science results in a media teleconference at 2 p.m. EDT Thursday, May 25, when multiple papers with early findings will be published online by the journal Science and Geophysical Research Letters. The teleconference participants are: Diane Brown, program executive at NASA Headquarters in Washington Scott Bolton, Juno principal investigator at Southwest Research Institute in San Antonio Jack Connerney, deputy principal investigator at NASA's Goddard Space Flight Center in Greenbelt, Maryland Heidi Becker, Juno radiation monitoring investigation lead at NASA's Jet Propulsion Laboratory in Pasadena, California Candy Hansen, Juno co-investigator at the Planetary Science Institute in Tucson, Arizona To participate in the teleconference, media must email their name and affiliation to Laurie Cantillo at laura.l.cantillo@nasa.gov by noon Thursday. Media and the public also may ask questions during the briefing on Twitter using #askNASA. Juno launched on Aug. 5, 2011, from Cape Canaveral Air Force Station, Florida, and arrived in orbit around Jupiter on July 4, 2016. In its current exploration mission, Juno soars low over the planet's cloud tops, as close as about 2,100 miles (3,400 kilometers). During these flybys, Juno probes beneath the obscuring cloud cover of Jupiter and studies its auroras to learn more about the planet's origins, structure, atmosphere and magnetosphere.

	May 22, 2017  MEDIA ADVISORY M17-060 NASA TV Coverage Set for May 23 Space Station Contingency Spacewalk NASA astronauts Peggy Whitson, seen here on her record-breaking eighth spacewalk in March 2017, and Jack Fischer will venture outside the International Space Station May 23, 2017, to conduct the 201st spacewalk in support of space station assembly and maintenance. Credits: NASA NASA astronauts Peggy Whitson and Jack Fischer are preparing for an unscheduled spacewalk outside the International Space Station Tuesday, May 23. Live coverage will begin at 6:30 a.m. EDT on NASA Television and the agency's website. Whitson, Expedition 51 commander, and Fischer, flight engineer, will replace a critical computer relay box that failed May 20. The relay box, known as a multiplexer-demultiplexer (MDM), is one of two units that regulate the operation of radiators, solar arrays and cooling loops. They also route commands to other vital station systems. Because each MDM is capable of performing the critical station functions, the crew on the station is in no danger and station operations are not affected. The failed relay box was installed in the space station truss March 30 during a spacewalk by Whitson and Expedition 50 commander Shane Kimbrough. Whitson prepared a spare data relay box May 21, and tested components installed in the replacement. She reported the spare MDM is ready to be brought outside to replace the failed unit. The spacewalk to replace the failed box is planned to last about 2.5 hours. While Whitson is replacing the MDM, Fischer will install a pair of antennas on the U.S. Destiny Laboratory module to enhance wireless communication capability for future spacewalks. The spacewalk will be the 201st in support of space station assembly and maintenance, the sixth spacewalk conducted from the Quest airlock this year, the 10th for Whitson and the second for Fischer. Whitson, who already is the leading female spacewalker in history, will be designated extravehicular crew member 1 (EV-1) wearing a suit with red stripes. Fischer will be designated as EV-2, wearing a suit with no stripes.
