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