- Space is an incredibly dangerous place.
-
If you do something wrong, it's game over,
-
so the stakes are very high.
-
To keep everyone safe, we practice routinely
-
emergency procedures.
-
I think the biggest emergency is
-
is loss of depress, or depressurization.
-
If something's coming at you and hits the Space Station
-
then that's gonna cause a breach.
-
And it can be something as small as two centimeters
-
in diameter that could do a lot of damage.
-
Everyone would go to their respective vehicle
-
and close the hatches because initially, if it's
-
very fast, you only have so much time
-
to get in that vehicle safely
-
and be ready to go home.
-
Another situation we train for is
-
fire.
-
If a fire alarm goes off
-
on our computer screen you would see
-
the actual module where the smoke detectors
-
think you're seeing a fire.
-
And then you would actually physically go there
-
to see if you actually have identified smoke,
-
or flames, or anything coming out.
-
And the solar flare, the sun kind of burps
-
every so often, and sends out high energy particles
-
from the sun.
-
The dangers around solar flares are that you can
-
accumulate too much radiation in your body.
-
If there's a solar flare, all of the astronauts float
-
up into the doghouse, we call it
-
that has a ton of water bags
-
surrounding it.
-
And the water will absorb and keep the radiation
-
from coming into our bodies.
-
And we can just wait until
-
Houston gives us the call to say everything's clear.
-
As astronauts, you're trained to not be alarmed
-
by things.
-
You're trained to go into a mode of
-
how will I save the day,
-
how will I fix this,
-
how will I do all the steps required
-
to make sure that, you know, we come home safely?
