After spending a few days putting together my spacesuit and tools, today I tried them on. Like a dress rehearsal!

Après avoir passé quelques jours à assembler ma combinaison et mes outils, je les essaie aujourd'hui. Comme dans une répétition générale!

A long week of hard work and spacewalk prep calls for a pizza party. Making pizza in space is similar to making pizza on Earth, the only difference is our ovens look a little different and our pizza can float! Anyone on Earth having pizza tonight?

Aurora australis dancing over the South Pole. Just as graceful and magnificent as their northern sisters!

Monday's Spacewalk Will Be Broadcast Live on NASA TV

Expedition 59 Flight Engineers Anne McClain of NASA and David Saint-Jacques of the Canadian Space Agency are scheduled to conduct another spacewalk Monday, April 8, to establish a redundant path of power to the Canadian-built robotic arm, known as Canadarm2, and install cables to provide for more expansive wireless communications coverage outside the orbital complex, as well as for enhanced hardwired computer network capability.

Watch the spacewalk on NASA TV and on the agency's website. Live coverage of the spacewalk will begin at 6:30 a.m., and is expected to last about 6.5 hours. The spacewalk is set to start at 8:05 a.m.

This will be the 216th spacewalk in support of space station assembly and maintenance. McClain will be designated extravehicular crew member 1 (EV 1), wearing the suit with red stripes. Saint-Jacques will be designated extravehicular crew member 2 (EV 2), wearing the suit with no stripes.

This is the third spacewalk in under a month on the space station. The first two spacewalks installed powerful lithium-ion batteries for one pair of the station's solar arrays. On March 22, the first spacewalk in the series was completed by McClain and fellow NASA astronaut Nick Hague. On March 29, the second spacewalk was completed by Hague and NASA astronaut Christina Koch.

The spacewalking work continues the overall upgrade of the station's power system that began with similar battery replacement during spacewalks in January 2017.

Astronauts Conducting Third Spacewalk to Upgrade Station Power Systems

NASA astronauts Anne McClain and David Saint-Jacques have begun the third spacewalk in under a month on the exterior of the International Space Station. Today's spacewalk will work to establish a redundant path of power to the Canadian-built robotic arm, known as Canadarm2, and install cables to provide for more expansive wireless communications coverage outside the orbital complex, as well as for enhanced hardwired computer network capability.

Watch the spacewalk on NASA TV and on the agency's website.

The spacewalkers set their spacesuits to battery power this morning at 7:31 a.m. EDT then exited the Quest airlock into the vacuum of space. The team will spend about six-and-a-half hours installing truss jumpers to provide a redundant power source for the Canadarm2 robotic arm.

This is the 216th spacewalk in support of space station assembly and maintenance. McClain will be designated extravehicular crew member 1 (EV 1), wearing the suit with red stripes. Saint-Jacques will be designated extravehicular crew member 2 (EV 2), wearing the suit with no stripes.

Astronauts @AstroAnnimal and @Astro_DavidS started their spacewalk today at 7:31am ET today. They'll work outside for about 6.5 hours upgrading the station's power systems.

US EVA-54: After a spacewalk 3/22, to help install 3 new li-ion batteries in the station's power truss, engineers discovered one wasn't working properly; they also found problems with a battery charge-discharge unit

US EVA-54: Flight controllers using the station's robot arm removed both suspect components, then installed a spare BCDU and one of two older nickel-hydrogen batteries that had been removed to make way for the new li-ion power packs

US EVA-54: During today's EVA, McClain and Saint-Jacques will relocate an adapter plate, used to permit the replacement of two nickel-hydrogen batteries with one li-ion unit, to make way for the robotic installation of a second nickel-hydrogen battery

US EVA-54: That should restore power channel 4A to normal operation; a replacement li-ion battery will be launched and installed at some point down the road
