Is there an 'up' in space?
« on: 14/04/2016 01:50:02 »
Loyiso asked the Naked Scientists:
   Does one feel the upsidedowness in space - is there any kind of orientation like we feel here on earth. In other words is there an up or a down in space?
What do you think?

No. Our sensation and ideas of up and down have always been in relation to the direction of the gravitational field in our vicinity.

I think it is wrong to say no Pete, I would say we don't know, because we can only determine ''up'' by the  opposite gravitational direction but we do not know if there is a Universal ''up''.

Most astronauts feel some degree of space-sickness.

After habituation to space, up and down is merely a matter of convention.

One astronaut relates how he was intimitely familiar with the layout of the ISS through working with mockups on the ground. But as soon as he arrived, he was totally lost - he knew what ISS module he was in, but everything looked just "wrong" and unfamiliar. Then another astronaut spun him around so he was pointing in the same direction as he would be on the mockup on Earth, and everything jumped into focus.

I understand NASA are now using virtual reality helmets so the astronauts can become familiar with the ISS from all orientations, and get used to the lack of a defined "up" and "down".
