Hi Dr. D. 00:00:00
Hi guys, how's your project going? 00:00:02
It's going well, but we still need to learn more about training and adapting to living in space. 00:00:04
I'll give you an example about adapting here on Earth. 00:00:08
When astronomers go to work at the observatories on top of Mauna Kea in Hawaii, 00:00:10
which is almost 14,000 feet above sea level, they have to adapt to a new environment. 00:00:14
But if it's on Earth, why do they have to adapt? 00:00:18
At that very high elevation, there's much less options than here at sea level. 00:00:21
In order to adapt, astronomers go part way up the mountain, to about 9,000 feet, 00:00:25
and spend about 24 hours there at this elevation where the conditions are not quite as extreme. 00:00:29
What happens if they don't? 00:00:33
Astronomers might get altitude sickness. 00:00:35
If they take this time to let their bodies get used to less oxygen, 00:00:37
they might not suffer such symptoms as headaches or severe tiredness when they get to the top of the mountain. 00:00:41
That's really interesting. 00:00:46
Let's play a little game to see if you can adapt to a new environment. 00:00:48
Are we going to climb a mountain? 00:00:51
No, I'm going to put you in a mirror image environment. 00:00:53
What you have to do is trace this star looking in the mirror. 00:00:56
Just stay between the lines. 00:00:59
This looks really easy. I want to go first. 00:01:01
Go ahead and give it a try. 00:01:03
Wow, I can't move my hand. 00:01:10
This is really strange. 00:01:13
I bet I could do much better. 00:01:15
It's harder than it looks. 00:01:17
Alright, let me try it again. 00:01:20
Alright, go ahead and let her start. 00:01:22
It's easier this time. 00:01:27
It's still hard, but I'm able to do it better this time. 00:01:29
If you're learning how to adapt to this new environment, 00:01:32
you might want to learn more about how people train to live in space. 00:01:35
Where should we go? 00:01:38
I don't know. You might check out the NASA website. 00:01:40
If anyone knows, they should. 00:01:42
Thanks, Dr. D. Bye. 00:01:44
Bye. 00:01:46
