NASA's First New Spacesuit In 20 Years Is Its Own Airlock
Zothecula writes "The current U.S. space suit used by NASA is a dinosaur. Designed in 1992, it was only ever intended to be used by crews aboard the Space Shuttle and the International Space Station (ISS). That may have been good enough in the days of 14 kps modems, but with eyes turning increasingly toward missions to the Moon, Mars and the asteroids, space explorers need something better. That's why NASA is designing its first new suit in twenty years. Developed by NASA's Advanced Exploration Systems (AES), the Z-1 prototype space suit currently undergoing vacuum testing at the Johnson Space Center is a wearable laboratory of new technology. And it's a hatchback."
and beyond!
20 years old and it is a dinosaur? You young'ins are obsessed with the Shiny.
Leaving a spacesuit docked on a ship and now having nothing but the structural integrity of that suit between a crew and hard vacuum doesn't sound like a particularly bright idea.
As much as I value the space program, I am questioning the need for designing a new space suit.
Congress constantly targets NASA for budget cuts...
With its limited budget NASA seems more interesting in robotic flights instead of manned flights. They seem to be using more things like the Mars Rover.
We do not even have a space fleet right now. The shuttles have been mothballed and sold off as museum pieces and we now send people to the space station by buying them passage on soviet vessels launched out of Kazakhstan.
The future of manned space flight seems to be private industry in the US. How come NASA is spending the money designing suits instead of the future space companies?

I believe the Soviets had a "hatch-back" earlier. I expect it makes suiting up quite a bit faster and simpler.
It doesn't seem that way. These suits can act a higher pressure which allows them to dock to the spacecraft in the first place. So they must be sturdier.
Also, it's not like when the suit leaves that the ship is exposed to space. There must be an additional "hatch" that is closed around the suit opening to allow it to leave.
So when docked you have the structural integrity of the suit itself (life support backpack plus suit plus helmet) and the structural integrity of the "hatch" that is not mentioned.
It's not a full blown traditional airlock because there is not a separate space that has to have the pressure equalized before you can enter the space craft. In a way it is a mini-airlock because you will still need to equalize that small space in between the hatch and the suit.
The greatest advantage to this is speed. No pre-breathing and cycle time in a big airlock. You could be out in space in minutes it sounds like, or less.
Shouldn't that be the hatchback of Notre-dame?
To infinity and beyond! (Is it just me, or have they actually built Buzz Lightyear?)
The greatest advantage to this is speed. No pre-breathing and cycle time in a big airlock. You could be out in space in minutes it sounds like, or less.
The other great advantage is that one person should be able to put on their own suit - now, it takes substantial help from a partner.
You also avoid tracking anything that gets onto the suit into the vehicle with these things. The Apollo crews can tell you how big a deal that is for a mission of any duration, and it looks like Mars dust is if anything worse.
Manned space exploration isn't funded because we need to. It is funded because we want to. It is basically a fancier version of the Blue Angels. Mars rovers can look as unaesthetic as you want. But an astronaut, who theoretically could be fighting giant octopuses and pirates in space needs to look right. NASA should really talk to Blizzard or Bioware about how to make astronauts look like Space Marines.
a few Anglo-Saxon guys pocket the rest of the cash.
Oh, them. That's the Beowulf cluster you've heard tell of.
No no no, we're talking about a spacesuit here. :P
There's wind erosion on Mars so the dust over there is pretty smooth... nothing like the jagged nasty Moon stuff.
"It does seem that the few private companies are making more progress in 5 years than NASA can in 15"
Private companies are not even at Gemini level; that's about NASA's 45 years ago, so I'd say you are a bit overenthusiastic, don't you think so?
The atmosphere inside was pure oxygen at 0.2 bar, allowing the walls of the LEM to be very thin. Still, more like an oil drum than like tinfoil.
It made me think of the film Andromeda Strain (1969), but while googlising for a picture, I found this 1954 image from a nuclear facility.

Yes, these have 'tails', but the climbing-in-through-the-back part is there.
