Spacesuit Comparison

So after reading a fascinating account on what its like to use NASA’s Extravehicular Mobility Unit (EMU) in the Neutral Buoyancy Laboratory (NBL) I thought I’d compare the EMU to other manned spacesuits. Mainly it started as me wanting to satisfy my curiosity on the subject so why not post it all here? 

Now, there are only three nations that have put humans into orbit. Russia, The United States, and China. There are many types of spacesuits though, but for the sake of simplicity I’m only going to focus on the EVA kind that are in use today. EVA stands for extra-vehicular activity if you aren’t aware. I like that term better considering you don’t really use your feet too much during EVA’s and even on the moon there isn’t any walking. 

So I’m not going to go over the technical details of each space suit. Just basically going to compare the specs to get a good idea of how they stack up. It should be noted though that the EMU is generally more maneuverable due to lower pressure in the suit and because the gloves are custom built for each astronaut. 

Which basically means an astronaut can get more done due to less fatigue and the ability to work with various tools easier. Also just to make things clear below life support is mission life support, not total life support. As you spend a bit of time in the airlock pre-breathing so you don’t get the bends

W = Weight

LS = Life Support

BS = Backup Life Support

Time = The longest each suit was used to date. For all three they are also the longest EVA’s for each nation. The United States holds the all time record listed below that was set during STS-102 To put those times into further prospective the longest single EVA on the moon was 7 hours, 36 minutes. That was during Apollo 17 using the famous Apollo program suit.

  W:  275 lb (124.7 kg)                 265 lb (120 kg)                264 lb (120 kg)

  LS:  8 Hours                        8 Hours, 30 minutes             4 Hours

  BS:  30 minutes                                                               30 minutes

Time: 8 hours, 56 minutes     7 hours, 29 minutes             22 minutes

Anyway, as you can see the EMU is far more capable of the three. Though it should be noted that comes at a cost of 12 million a piece, while the other two cost at least 4 million a piece. Plus there are other considerations. The Russian & Chinese spacesuits aren’t brought back to earth due to how cramp the decent module is of the Soyuz and Shenzhou spacecraft. So they’re usually allowed to burn up in the service module/progress spacecraft or stored aboard station. Though, in a few cases the cosmonauts at least have just pushed out the old suit to let it float away and burn up while wearing the new suits. 

The one occasion in which this event was documented was in 2006 when the Russian’s turned an old Orlan suit into a satellite experiment called Suitsat 1.

First Woman

Today is best known for being the day in which we honor men for their role as fathers, less known is that this date 50 years ago the first woman was launched into space. Valentina Tereshkova grew up in the Soviet Union with a modest upbringing, her father was a tractor driver and her mother a textile worker. Her desire to sore lead to her being very good at parachute jumping, which eventually lead to her being picked to be a cosmonaut. On this date 50 years ago she was the first woman to soar into space and return, but she wasn’t the last as Wang Yaping of China became the 57th woman on the 11th of this month.


That is 57 out of 534 space travelers total as it stands at the moment. Or a little more than 10 percent.
I personally would like to see things even out a bit more. Not because I believe women should be space travelers or explorers per say but if they choose to do so they should go for it. Everyone in this life can be anything they choose to be including you and don’t let anyone tell you different including yourself. Cheers, and happy fathers day all. :)

Space Gizmo

Okay, so while I’ve said it at least two other times in the past two years, I am attempting to get Space Gizmo back up and running properly. That includes spacegizmo.com, but until I do get the website up and running at least back to the way it was I am going to post here. Or try to, no promises.


I’m not going to delete any pictures that have been liked, or reblogged, as this used to be my personal tumblr. Now I have gizmoman. and while I haven’t really taken any pictures in a while you can follow me there if you choose to. Or not, whatever. :) Onward to being productive and creative. Its a daily struggle, but a worth while one.
