What about using hydrogel instead of gel?

Yo got the idea right! Though it has many problems and flaws, I think it can be feasible!It is great idea for my course project! For turning gel into aerogel we use some CO2,is that right?

If when the astronaut gets into gel, we turn the back segment of the gel into aerogel,the segment which is in the airlock,then no air is lost!

I understand that there are more than fifty different kinds of aerogels, so you are saying there is none of them that is not porous and is impervious?!

What is your opinion about my previous comment?

Hi Mike, I've thought about the inflatable structure outside the airlock, but I think the power used to depressurize the space between the balloons is much more than the airlock and the time to do that is so high. Dear Ryan_m_b your comment put an idea to my mind. What if we don't make the gel...

Isn't there some kind of material that can act like gels but isn't composed of water?

Yes,also we can put it in one place with the use of magnetic field.Is there some kind of material that can act like jelly in vacuum?

Thank you Mike B Hopkins for all the effort,but I'm not satisfied with what I wanted yet.I think a mechanism that acts like jelly and astronaut can get inside it is better anyway. Don't you think?

So what you're saying is we need to exert force to the air molecules on the exit segment of the airlock . So why don't we use some high pressure air at the exit instead of plasma?wouldn't it be easier?I think it would require less power and less time to prepare!what do you think?!

Thanks MikeBH,very good, but I have some concerns.What is your opinion about these: 1. 1000 Pa equals about 0.3 psi, but our suit operates at very low pressure which is 4.3 psi, so lowering the room pressure to 0.3 psi would need great deal of time and power. This power loss added to the power...

Thanks,nice points! I've thought about donning suits in higher pressures like 8 psi and then until we reach the destination lowering pressure for the dexterity, but there are constraints in suit materials I think. What do you suggest for breathing oxygen outside?

Dear Travis, I'm thinking about a large scale station and in it the tiny bit of air and oxygen are important! We don't have much available sources in long distance trips for example to mars,to produce needed oxygen for daily use so we must get the best of the available air, so we don't want to...

@Travis: So we try to come up with an idea to both lower the power and cost needed and lower the air loss! @Ryan: Don't you think it'll be good if an autonomous system catches them?! We had some cases where astronaut couldn't find the airlock door or couldn't ingress the airlock! So let's think...

By Returning I mean that when astronaut does his/her job and wants to get back to airlock. i think it is better if astronaut gets close enough to a distance to the craft and then an autonomous system catches him and attaches him to the craft.In the suitport, donning and doffing are not...
