Spacewalk Recap Told in GIFs
Friday, Oct. 20, NASA astronauts Randy Bresnik and Joe Acaba ventured outside the International Space Station for a 6 hour and 49 minute spacewalk. Just like you make improvements to your home on Earth, astronauts living in space periodically go outside the space station to make updates on their orbiting home.
During this spacewalk, they did a lot! Here’s a recap of their day told in GIFs…
All spacewalks begin inside the space station. Astronauts Paolo Nespoli and Mark Vande Hei helped each spacewalker put on their suit, known as an Extravehicular Mobility Unit (EMU).
They then enter an airlock and regulate the pressure so that they can enter the vacuum of space safely. If they did not regulate the pressure safely, the astronauts could experience something referred to as “the bends” – similar to scuba divers.
Once the two astronauts exited the airlock and were outside the space station, they went to their respective work stations.
Bresnik replaced a failed fuse on the end of the Dextre robotic arm extension, which helps capture visiting vehicles.
During that time, Acaba set up a portable foot restraint to help him get in the right position to install a new camera.
While he was getting set up, he realized that there was unexpected wearing on one of his safety tethers. Astronauts have multiple safety mechanisms for spacewalking, including a “jet pack” on their spacesuit. That way, in the unlikely instance they become untethered from the station, the are able to propel back to safety.
Bresnik was a great teammate and brought Acaba a spare safety tether to use.
Once Acaba secured himself in the foot restraint that was attached to the end of the station’s robotic arm, he was maneuvered into place to install a new HD camera. Who was moving the arm? Astronauts inside the station were carefully moving it into place!
And, ta da! Below you can see one of the first views from the new enhanced HD camera…(sorry, not a GIF).
After Acaba installed the new HD camera, he repaired the camera system on the end of the robotic arm’s hand. This ensures that the hand can see the vehicles that it’s capturing.
Bresnik, completed all of his planned tasks and moved on to a few “get ahead” tasks. He first started removing extra thermal insulation straps around some spare pumps. This will allow easier access to these spare parts if and when they’re needed in the future.
He then worked to install a new handle on the outside of space station. That’s a space drill in the above GIF.
After Acaba finished working on the robotic arm’s camera, he began greasing bearings on the new latching end effector (the arm’s “hand”), which was just installed on Oct. 5.
The duo completed all planned spacewalk tasks, cleaned up their work stations and headed back to the station’s airlock.
Once safely inside the airlock and pressure was restored to the proper levels, the duo was greeted by the crew onboard.
They took images of their spacesuits to document any possible tears, rips or stains, and took them off.
Coverage ended at 2:36 p.m. EDT after 6 hours and 49 minutes. We hope the pair was able to grab some dinner and take a break!

Back-to-Back Friday Spacewalks
On Friday, Jan. 6 and Friday, Jan. 13, astronauts on the International Space Station will step outside to perform spacewalks.
What’s a spacewalk? It’s any time an astronaut gets out of a vehicle or spacecraft while in space. It can also be called an EVA (extravehicular activity).
Astronauts go on spacewalks for many reasons. These activities allow crew members to work outside their spacecraft (in this case the space station).
So what specific tasks will astronauts perform in these two upcoming spacewalks? Let’s take a look…
Both spacewalks are being performed to upgrade the orbital outpost’s power system.
The crew members will install adapter plates and hook up electrical connections for six new lithium-ion batteries that were delivered to the station in December.
NASA astronauts Shane Kimbrough and Peggy Whitson will perform the first spacewalk on Jan. 6. The work will continue Jan. 13 during the second spacewalk, which will be conducted by Kimbrough and ESA astronaut Thomas Pesquet.
Prior to each spacewalk, the new batteries will be robotically extracted from a pallet to replace 12 older nickel-hydrogen batteries through a series of robotic operations.

Large Sun Room in New York Inspiration for a large timeless slate floor sunroom remodel with a glass ceiling
Hey y’all! I wanted your opinion on something. My laptop for the past five years has died, it’s dead and gone. And I was wondering would it be best for me to just get some cheapo $200 computer and hope for the best or save up for like a $400 $500 computer that’ll last me for longer and treat me better? By the way I am like a first year college student who has access to computers on campus. And I already went to a computer technician who is backing it for like $50, so my files are not lost.
This is one of the oldest conundrums of personal finance: to spend a small amount of money on a bandaid solution NOW, or save up for a long-term solution later. We wrote about the dilemma here:
It’s More Expensive to Be Poor Than to Be Rich
Personally, if you can get by using the computers at school, then I would save up another few hundred dollars to buy the higher quality computer that will last longer. It’ll be cheaper in the long term, and you’ll rest easy knowing that you won’t have to deal with another computer combustion any time soon. Good luck!
That’s Louis Rossman, a repair technician and YouTuber, who went viral recently for railing against Apple. Apple purposely charges a lot for repairs and you either have to pay up or buy a new device. That’s because Apple withholds necessary tools and information from outside repair shops. And to think, we were just so close to change.
