Friday Stroll? How About a Spacewalk?

On Friday, May 12, NASA astronauts Peggy Whitson and Jack Fischer will venture outside the International Space Station, into the vacuum of space, for a spacewalk.

Space Fact: This will be the 200th spacewalk performed on the space station!

You can watch their entire 6.5 hour spacewalk live online! (Viewing info below!) To tell the two astronauts apart in their bulky spacewalk suits, Whitson will be wearing the suit with red stripes, while Jack Fischer will have white stripes.

Space Fact: The first-ever spacewalk on the International Space Station was performed on Dec. 7, 1998.

For Peggy, this will be her ninth spacewalk! She actually holds the record for most spacewalks by a female astronaut. For Fischer, this is his first time in space, and will be his first spacewalk. You can see from the below Tweet, he’s pretty excited!

Once both astronauts venture outside the Quest airlock, their tasks will focus on:

  1. Replacing a large avionic box that supplies electricity and data connections to the science experiments
  2. Replacing hardware stored outside the station

Specifically, the ExPRESS Carrier Avionics, or ExPCA will be replaced with a unit delivered to the station last month aboard the Orbital ATK Cygnus cargo spacecraft.

Ever wonder how astronauts prepare and practice for these activities? Think about it, wearing a bulky spacesuit (with gloves!), floating in the vacuum of space, PLUS you have to perform complex tasks for a period of ~6.5 hours! 

In order to train on Earth, astronauts complete tasks in our Neutral Buoyancy Laboratory (NBL). It’s a gigantic pool with a full mock up of the International Space Station! Here’s a clip of astronauts practicing to install the ExPCA in that practice pool at Johnson Space Center in Houston. 

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 the cosmic ray detector.

The astronauts will also install a protective shield on the Pressurized Mating Adapter-3, which was moved in March. This adapter will host a new international docking port for the arrival of commercial crew spacecraft.

Finally, the duo will rig a new high-definition camera and pair of wireless antennas to the exterior of the outpost.

Live coverage will begin at 6:30 a.m. EDT, with spacewalk activities starting at 8 a.m. EDT.

  • To Tim: What’s the difference between writing for  the comics vs the show? 
    • The comics happen so fast, write the adventure and 3 months later it comes out, and there’s no production limitation with comics, in terms of how much Voltron can be in or how many giant monsters they can plug
  • Every paladin has bonded more with their lions - where can they go from now? 
    • Tim: “Bonds can become closer” plenty more to unlock emotionally and intellectually, we’ll see who steps up
    • Bex: bond with lion like bond with people - it can deepen and develop over life, will keep going and evolving
    • As seen with Zarkon, a bond with a lion can be broken, and a bond can be damaged if you betray the lion
    • Tyler: Just cause you form a relationship doesn’t mean they show you everything right away - nuances to the relationship
  • What was fun to discover with characters 
    • Bex really likes 1st ep. Season one Pidge is all family, then she has realization that these have become her people; catapulted into community growth instead of just self growth
    • Tyler enjoyed going to new depths, not just regular scenario like school, higher stakes cause defending universe. Lots of characters (esp Hunk) were a bit of a mess in the beginning and then became more sure-footed, all paladins got that in season 2 to an extent
    • Ty’s fave character to watch was Keith, his internal struggle and the test with the BoM. Almost like watching a superhero origin story - want to see the person becoming the hero
    • “we have 5 superheroes and they’re always progressing”
  • Fave scenes: 
    • Ty: the space caterpillars, when they came out with theglowing  eyes
    • Image of Pidge smuggling some onto castle “she must’ve” “Pidge is a hoarder so-” “castle is big” 
    • Ty: another awesome moment was getting farted out of the weblum, found it hilarious
    • Tim: fun how Hunk and Coran went to get the crystal and mentioned the weblum - foreshadowing, things pay off
    • Bex: when Coran thinks he’s gonna fly the lion. Tim: it’s a suit he made, he didn’t steal Alfor’s 
  • Pidge and Hunk seem much more the ambassadors of the team - good at getting aliens to trust them
    • Ty: Hunk can trust himself in a situation, his softer side really services him like on the mermaid planet. He’s approachable and likeable and personalbe, it’s a skillset and he’s learning to embrace it 
    • Tim: Hunk is able to see multiple sides of a situation, never forgets how crazy this situation they’re in is, he’ able to put himself in other’s shoes
    • Bex: Pidge communicates with technology, needs an extra step to make that connection with people. So when she meets the Olkari it’s like “these are people I can actually communicate with
