1
00:00:00,269 --> 00:00:04,740
THE INTERNATIONAL SPACE STATION IS A
NATIONAL ORBITING LABORATORY EVERY

2
00:00:04,740 --> 00:00:08,910
SINGLE DAY WE ARE ANSWERING BIG
QUESTIONS ABOUT EARTH AND ABOUT SPACE

3
00:00:08,910 --> 00:00:11,496
ABOUT WHERE WE CAME FROM 
AND ABOUT WHERE WE'RE GOING

4
00:00:11,496 --> 00:00:12,540
ONE CATEGORY OF THOSE

5
00:00:12,540 --> 00:00:15,599
EXPERIMENTS ARE HUMAN RESEARCH
EXPERIMENTS ON OUR HUMAN BODY HOW WE

6
00:00:15,599 --> 00:00:16,581
REACTED MICROGRAVITY

7
00:00:16,581 --> 00:00:19,380
ONE OF THE RECENT
ONES THAT I'VE BEEN A PART OF IS CALLED

8
00:00:19,380 --> 00:00:24,320
AIRWAY MONITORING AND THIS IS LOOKING AT
AIRWAY INFLAMMATION UP IN SPACE

9
00:00:24,320 --> 00:00:28,640
SO WHEN WE'RE BREATHING THE AIR YOU KNOW
THE SMALL PARTICLES IN THE AIR THEY DON'T

10
00:00:28,680 --> 00:00:32,900
JUST FALL TO THE GROUND LIKE DUST ON THE
ON THE GROUND SO WE TEND TO INHALE MORE

11
00:00:32,910 --> 00:00:38,790
FINE PARTICLES THAN WE WOULD ON EARTH
AND SO WE'RE LOOKING AT THE OUR RESPONSE

12
00:00:38,790 --> 00:00:44,430
OUR BODY'S RESPONSE TO THAT BY MEASURING
NITRIC OXIDE EXHALATIONS AS AN INDICATOR

13
00:00:44,430 --> 00:00:48,030
FOR AIRWAY INFLAMMATION AND SO
UNDERSTANDING YOU KNOW HOW CLEAN IS OUR

14
00:00:48,030 --> 00:00:51,690
AIR NEED TO BE HOW DOES OUR BODY REACT
TO THE TO THE AIR WHEN WE TALK ABOUT

15
00:00:51,690 --> 00:00:55,800
GOING BACK TO THE MOON YOU KNOW A LOT OF
PEOPLE ARE AWARE THAT THE MOON DUST IS A

16
00:00:55,800 --> 00:01:00,239
VERY VERY FINE PARTICLE IT'S ALMOST LIKE
POWDERED SUGAR FINE PARTICLE AND IF

17
00:01:00,239 --> 00:01:03,960
THAT'S IN THE AIR AND WE'RE BREATHING
THAT FOR MONTHS ON END IF WE'RE IF

18
00:01:03,980 --> 00:01:08,180
WE'RE DOING YOU KNOW EXTENDED STAYS ON
THE LUNAR SURFACE YOU KNOW WE NEED TO
