1
00:00:08,450 --> 00:00:06,499
water is the foundation of life on earth

2
00:00:10,669 --> 00:00:08,460
and without water life as we currently

3
00:00:12,740 --> 00:00:10,679
know it wouldn't exist the same goes for

4
00:00:15,079 --> 00:00:12,750
our astronauts in space whether living

5
00:00:16,790 --> 00:00:15,089
in spaceships or in planetary bases our

6
00:00:19,220 --> 00:00:16,800
space travelers remains fresh drinking

7
00:00:20,810 --> 00:00:19,230
water to sustain life as we design and

8
00:00:23,000 --> 00:00:20,820
build water purification systems for

9
00:00:24,800 --> 00:00:23,010
long-duration space missions we can use

10
00:00:28,250 --> 00:00:24,810
what Mother Earth has perfected to

11
00:00:30,290 --> 00:00:28,260
purify water working at NASA we're

12
00:00:32,990 --> 00:00:30,300
developing a way to use biomimetic

13
00:00:35,510 --> 00:00:33,000
systems on earth to purify water in

14
00:00:37,880 --> 00:00:35,520
space our bio reactors break down

15
00:00:39,709 --> 00:00:37,890
wastewater using microorganisms like

16
00:00:42,139 --> 00:00:39,719
your septic tanks at home

17
00:00:44,090 --> 00:00:42,149
algae then remove high concentrations of

18
00:00:46,729 --> 00:00:44,100
nitrogen compounds while producing

19
00:00:49,069 --> 00:00:46,739
biomass and breathable oxygen the

20
00:00:51,560 --> 00:00:49,079
nutrient-rich water can then be used to

21
00:00:53,540 --> 00:00:51,570
grow plants the plants further clean the

22
00:00:56,240 --> 00:00:53,550
water by removing impurities while

23
00:00:58,189 --> 00:00:56,250
growing fresh food and in the end after

24
00:01:01,130 --> 00:00:58,199
all these stages you have clean potable

25
00:01:03,110 --> 00:01:01,140
water as we build technologies to purify

26
00:01:05,210 --> 00:01:03,120
water in space using lessons learned

27
00:01:06,980 --> 00:01:05,220
from mother nature we can also give back

28
00:01:08,960 --> 00:01:06,990
on this Earth Day by helping clean the

29
00:01:10,460 --> 00:01:08,970
water here at home in the near future

30
00:01:13,160 --> 00:01:10,470
here at the Merritt Island National

31
00:01:14,929 --> 00:01:13,170
Wildlife Refuge we hope to deploy these

32
00:01:17,660 --> 00:01:14,939
lessons learned to help bring the us

33
00:01:19,580 --> 00:01:17,670
right back to its natural beauty this is

34
00:01:23,399 --> 00:01:19,590
how NASA contributes technologies from

35
00:01:23,680 --> 00:01:23,409
space exploration back to earth
