NASA Astronauts Space Walk Outside the ISS

Spacewalking astronauts face a wide variety of temperatures. In Earth orbit, conditions can be as cold as minus 250 degrees Fahrenheit. In the sunlight, they can be as hot as 250 degrees. A spacesuit protects astronauts from those extreme temperatures.

This footage was taken by NASA astronaut Peggy Whitson during a spacewalk on the International Space Station on Thursday, March 30, 2017. She was joined on the spacewalk by NASA astronaut Shane Kimbrough.

The two spacewalkers reconnected cables and electrical connections on PMA-3 at its new home on top of the Harmony module. They also installed the second of the two upgraded computer relay boxes on the station’s truss and installed shields and covers on PMA-3 and the now-vacant common berthing mechanism port on Tranquility.

During the spacewalk, one of the shields was inadvertently lost. The loss posed no immediate danger to the astronauts and Kimbrough and Whitson went on to successfully install the remaining shields on the common berthing mechanism port.

A team from the Mission Control Center at NASA’s Johnson Space Center in Houston devised a plan for the astronauts to finish covering the port with the PMA-3 cover Whitson removed earlier in the day. The plan worked, and the cover was successfully installed, providing thermal protection and micrometeoroid and orbital debris cover for the port.

Everyone talking about how scary this is and how they wouldn’t do it. I would do this in a heart beat. This is seriously one of the most beautiful things I’ve ever seen.

I can’t imagine how terrifying it would be to slowly drift off in the inky blackness

Just looking up in that void is actually terrifying. Like, its nothing but void, but seeing earth from that view is absolutely terrifying and amazing at the same time.

I keep coming back to this video because the sheer vastness of space is just outright fascinating.
The quietness, the darkness, an endless trip into nothing and anything at the same time.
The vast possibilities hidden in time and distance.
The fact that we will only exist in a microscopic duration relative of that to the universe, but is an unimaginable scale for us, is truly a miracle.
I love you all. Thank you for being here. I hope we can do better.

Man imagine going to space that will be the greatest satisfaction ever, no amount of money, social status could ever top that, your view of life will be probably be incredibly different

[gmmwtpq]

I cannot even possibly imagine, the kind of experience this is. I don’t think there’s anything that could top this. What an absolute sight. Imagine. Literally at this point, some humans somewhere we’re sleeping, some getting on with their day, some at a desk, some wrapping up for the night... just humans beings walking on two legs doing regular things all over the world.. and they were literally hovering on top of it. How.

This really humbles you. Everything that has ever existed and currently exists, the good, the bad, the ugly, for generations, all on that spinning rock that is our entire reality.

Despite the years of training and experience, the first time an astronaut does this, it has to be a feeling like nothing else a human can experience. It’s almost unreal to watch so being there must be literally unbelievable.

It looks scary, unbelievably terrifying dangling over the void. But if you had the opportunity, you would be the biggest fool in the solar system for not taking it.

I dont think there's a greater thing than this that a human can experience

[meganmarie]

If I was one of the astronauts I wouldn’t even want to work lol I’d just stare at the earth the whole time. It’s beautiful

[adamlancsak]

I know it's real but it still is unbelievable

[danielblair]

Look at that darkness man... that shit is terrifying

[c.jarmstrong]

Absolutely amazingly beautiful yet utterly terrifying all at once. I can only imagine being out there and seeing the planet from above must completely change your perspective

[panayiotiponiros]

Unimaginable the feeling youd get being an astronaut doing an 8 hour spacewalk .. id give anything to do it .. just think .. that astronaut on an 8 hour spacewalk orbited the earth just over 5x .. he literally seen the sun rise and set 5x in 8 hours .. incredible

[helibrrr]

Death doesn’t scare me, BUT THIS FREAKIN SILENCE DOES

[josh-sbhj]

This video is both beautiful and horrifying at the same time

[gsantiago]

There is something so strange about looking into that void of darkness - the atmosphere does a really good job of making what is beyond it not seem so cold and uncaring.

[gladtobeangry]

This is amazing footage. It;s all so clear and bright and serene. There's something about the way the light reflects off of all the surfaces like a bright clear summer morning, and then the "sky" in the background just being this pitch black nothingness. And the silence just makes it all feel all the more like a deceptively carefree walk in the sunshine on a nice day. Deceptively emphasized though, I'm well aware of all the actual dangers facing these astronauts. But looking at the footage, it really looks like an extraordinary thing to experience in person.
