Speaker 1 (00:00):
Fact of the day, day day day day do do
do do do do do do do do do do
do do do do do do do do do do do.
Today's are in fact of that it's space week.

Speaker 2 (00:18):
You're effected the day, loving it, influenced by a recent
tripne to find out more soon.

Speaker 1 (00:25):
I like that the space facts. Today's fact.

Speaker 2 (00:29):
How much gravity do you think there is on the
International Space Station gravity?

Speaker 1 (00:36):
I don't know gravity works, law, I don't feel confident
enough to be.

Speaker 2 (00:40):
I mean, here's a concise seem to explain how gravity works.
You see them floating around, so obviously there's it's less gravity.

Speaker 1 (00:51):
Yeah, seventy five Earth wouldn't float around that much. You'd
just be a bit more buoyant.

Speaker 2 (00:57):
Well, it's actually ninety percent of Earth's gravity, sucker, But
you're right, they float around.

Speaker 1 (01:03):
And how does that work of a zero gravity?

Speaker 2 (01:05):
Yeah, it's because they are falling like a skydiver free falling. Yeah,
they fall of that orbiting, so they're falling anger moving
sideways at a rate that it gives the appearance of
zero gravity even though it's nine of Earth's gravity.

Speaker 1 (01:22):
Does it just feel like.

Speaker 2 (01:22):
You know, when a plane does a sudden turn and
you can actually feel the g's and you try to
lift your leg and you can't Jesus what you feel
in the acceleration tour point, right, So when they take
off from Earth and they're in the space and they're
like a stuck to this seed and you're getting.

Speaker 1 (01:38):
Up there place and explode place.

Speaker 2 (01:40):
Yeah, but then to dock with the International Space Station,
they've got to be going the same speed as it.
So they did all the hard work leaving Earth, and
once they're on it, they can't feel the acceleration, and
the constant speed just feels like constant speed to.

Speaker 1 (01:51):
It, like how we can't feel the Earth spinning.

Speaker 2 (01:52):
So it's like when skydivers are free falling and they
can just spin around and it gives the appearance that weightless,
but everything's moving around them, whereas these are insider you know,
if they want to replicate zero gravity, they take you
up on that big plane and then they just dive
that plane down. It's effectively that way. The International Space
Station of sideways and falls towards woods Earth and the
horizon curves away beneath it at the same rate, so

(02:15):
it means it's orbiting around. Given the appearance of zero gravity,
but it's got ninety percent of Earth's gravity in there.
So today's fact of the day is that the International
Space Station is not zero gravity.
