LIVE: US EVA 42 - May 12, 2017
« on: 03/18/2017 10:23 AM »
Expedition 50 astronauts will conduct a spacewalk outside the International Space Station (ISS) in early April to prepare for the future arrival of U.S. commercial crew spacecraft and upgrade station hardware.

The spacewalk is currently scheduled for April 7. NASA TV will provide complete coverage beginning at 6:30 a.m., with the six-and-a-half hour spacewalks scheduled to begin about 7 a.m.

The final spacewalk will feature Whitson and Pesquet replacing an avionics box on the starboard truss called an ExPRESS Logistics Carrier, a storage platform. The box houses electrical and command and data routing equipment for the science experiments and replacement hardware stored outside of the station. The new avionics box is scheduled to launch aboard Orbital ATK’s Cygnus cargo craft this month.

This will be the 200th spacewalk in support of space station assembly and maintenance. Kimbrough’s two spacewalks will be the fifth and sixth of his career. Whitson will be making the ninth spacewalks of her career – more than any other female astronaut. Pesquet will undertake the third spacewalks in his career.

Update:
Third spacewalk now is scheduled for Thursday, April 6.

There is a report on the NK forum, that this EVA will be done by Peggy Whitson and Jack Fischer.

Yes, Fischer will join Whitson for EVA-42.

According to NASA, Pesquet has done 2 EVAs and ISS Program are keen to "spread the wealth" of EVA experience across the corps. No other EVAs planned for Fischer, so this gives him the opportunity to perform an EVA.

And why not Pesquet/Fisher ?

If Fisher is taking Pesquet's place then perhaps neither of them have trained for the tasks that Whitson will do.

ISS Daily Summary Report – 4/28/2017


Extravehicular Activity (EVA) Preparations: In preparation for the EXPRESS Pallet Controller Assembly (ExPCA) EVA currently scheduled for May 12, the crew utilized Dynamic Onboard Ubiquitous Graphics (DOUG) Software to review the translation paths that will be used. They also performed a procedures review including detailed timeline, cuff checklist, tool config and planned getaheads. These activities were followed by a conference with ground teams to address any questions or concerns.

ISS Daily Summary Report – 5/02/2017

Extravehicular Activity (EVA) Preparations: In preparation for the EXPRESS Pallet Controller Assembly  (ExPCA) EVA currently planned for May 12, the crew configured computers to record Extravehicular Mobility Units (EMUs) 3006 and 3008 operating data which ground teams will use for detailed analysis of the suits’ function. The crew also performed loop scrubs on the EMUs and filled the empty Liquid Cooling Venting Garments (LCVGs) with water which will provide cooling for the crew members during the EVA.

The crew is doing suit fit checks now
Best quote heard during an inspection, "I was unaware that I was the only one who was aware."

MEDIA ADVISORY M17-052
NASA TV Coverage Set for 200th Spacewalk at International Space Station

NASA astronauts Peggy Whitson and Flight Engineer Jack Fischer will perform a landmark 200th spacewalk at the International Space Station Friday, May 12. Live coverage will begin at 6:30 a.m. EDT on NASA Television and the agency’s website.

Whitson, Expedition 51 commander, and Fischer will venture outside the Quest airlock to replace a large avionics box that supplies electricity and data connections to the science experiments, and replacement hardware stored outside the station.

The ExPRESS Carrier Avionics, or ExPCA is located on the starboard 3 truss of the station on one of the depots housing critical spare parts. It will be replaced with a unit delivered to the station last month aboard the Orbital ATK Cygnus cargo spacecraft.

In addition, Whitson and Fischer will install a connector that will route data to the Alpha Magnetic Spectrometer and help the crew determine the most efficient way to conduct future maintenance on cosmic ray detector.

During the planned 6.5-hour spacewalk, the astronauts also will install a protective shield on the Pressurized Mating Adapter-3, which was moved from the Tranquility to the Harmony module in March. This adapter will host a new international docking port for the arrival of commercial crew spacecraft. Whitson and Fischer also will rig a new high-definition camera and pair of wireless antennas to the exterior of the outpost.

Whitson, who already holds the U.S. record for most spacewalks by a female astronaut, will make this ninth excursion as extravehicular crew member 1, wearing the suit with red stripes. Fischer, extravehicular crew member 2, will wear the suit with no stripes on his first-ever spacewalk.

The first spacewalk in support of International Space Station assembly and maintenance was conducted on Dec. 7, 1998, by NASA astronauts Jerry Ross and Jim Newman during space shuttle Endeavour’s STS-88 mission. Astronauts completed attaching and outfitting of the first two components of the station, the Russian Zarya module and the U.S. Unity module.

Thomas Pesquet


Not very common to see a spacesuit INSIDE the ISS! We verified 2fish’s fit check, so that everything is ready for Friday when he and Peggy will go out. He seized the opportunity to explore a little bit inside! I guess it’s the first ever IVA (intra vehicular activity) in the history of the ISS program!

•Detailed timeline and procedures review
•Briefing package review
•Tool configuration summary review
•Added EVA specific pages to the cuff checklist

Mobile Servicing System (MSS) Operations: Yesterday afternoon, Robotics Ground Controllers powered up the MSS, configured and stowed the Special Purpose Dexterous Manipulator (SPDM) on Mobile Base System (MBS) Power Data Grapple Fixture 2 (PDGF2) using the Space Station Robotic Manipulator System (SSRMS).  After stowing the SPDM, Controllers translated the Mobile Transporter from Worksite 3 (WS3) to WS4 and maneuvered the SSRMS into config for Friday’s ExPCA EVA.
