00:00:00,410 --> 00:00:05,227
Recipe: noun. A set of instructions for making
or preparing something;

2
00:00:05,227 --> 00:00:06,844
especially a food dish.

3
00:00:07,519 --> 00:00:08,570
Sounds simple enough?

4
00:00:08,570 --> 00:00:12,629
Well there’s a lot more to it than just
putting some  ingredients together.

5
00:00:12,982 --> 00:00:14,451
Hi this is Alton Brown.

6
00:00:14,451 --> 00:00:18,660
In order to successfully create a recipe,
say, a grilled cheese sandwich, you’ll need

7
00:00:18,660 --> 00:00:20,800
some bread and cheese, of course.

8
00:00:20,800 --> 00:00:22,869
A refrigerator to keep the cheese fresh.

9
00:00:22,869 --> 00:00:24,446
A pan to cook it in.

10
00:00:24,446 --> 00:00:25,955
A source of energy to heat the pan.

11
00:00:25,955 --> 00:00:27,020
A knife to spread some butter.

12
00:00:27,020 --> 00:00:28,529
A spatula to flip it.

13
00:00:28,529 --> 00:00:31,781
Spices scoured from the ends of the Earth…
you get the idea.

14
00:00:32,047 --> 00:00:34,985
And how about the food in our recipe.

15
00:00:35,445 --> 00:00:36,744
Where did you get it?

16
00:00:37,095 --> 00:00:38,000
How did it get there?

17
00:00:38,000 --> 00:00:39,010
Where did it come from?

18
00:00:39,334 --> 00:00:41,242
What sources were needed to grow it?

19
00:00:41,243 --> 00:00:42,224
Produce it?

20
00:00:42,224 --> 00:00:42,835
Package it?

21
00:00:43,141 --> 00:00:43,641
Preserve it?

22
00:00:43,872 --> 00:00:46,830
It’s a complicated and intricate network
of processes

23
00:00:46,830 --> 00:00:49,488
to get a simple grilled cheese sandwich on the table.

24
00:00:49,488 --> 00:00:53,384
But Earthbound humans have done a pretty good
job of putting systems in place

25
00:00:53,384 --> 00:00:54,921
to get it all done.

26
00:00:55,559 --> 00:00:58,362
But what about spacebound humans?

27
00:00:58,825 --> 00:01:03,923
Difficulty and distance aside, astronauts
on the International Space Station eat quite

28
00:01:03,923 --> 00:01:06,674
a healthy diet of fresh and freeze-dried foods

29
00:01:06,674 --> 00:01:10,061
thanks to semi-regular shipments originating from Earth.

30
00:01:10,339 --> 00:01:14,493
But to boldly go where no human has gone before

31
00:01:14,493 --> 00:01:18,147
we’ll need new and better ways to eat in space.

32
00:01:18,859 --> 00:01:23,903
Future astronauts on, say, a trip to Mars,
will spend years away from Earth and

33
00:01:23,903 --> 00:01:27,020
that means no quick trips to the grocery store.

34
00:01:27,020 --> 00:01:31,495
They’ll have to bring just about everything they’ll
need with them.

35
00:01:32,078 --> 00:01:37,314
Just like on Earth, when we prepare food in
space, we need not only the food ingredients

36
00:01:37,314 --> 00:01:43,070
themselves, but we also need energy, water
and other materials to transform the ingredients

37
00:01:43,070 --> 00:01:48,358
into nutritional — and tasty — meals that
astronauts will actually want to eat.

38
00:01:49,098 --> 00:01:55,340
So how do we reinvent food production systems
so that they are sustainable and work in space?

39
00:01:55,830 --> 00:01:57,139
Well that’s where you come in.

40
00:01:57,750 --> 00:02:01,410
NASA and the Canadian Space Agency are launching competitions,

41
00:02:01,410 --> 00:02:03,556
the Deep Space Food Challenge,

42
00:02:03,556 --> 00:02:07,667
and they're offering prize money for
anyone who can come up with novel ways to

43
00:02:07,667 --> 00:02:13,380
keep our astronauts fed on future long duration
space exploration missions.

44
00:02:13,917 --> 00:02:19,740
What’s really cool, aside from feeding interplanetary
humans, is that.these space-based food solutions

45
00:02:19,740 --> 00:02:25,130
could have transformative impacts on Earth’s
food systems — helping to resolve food insecurities

46
00:02:25,130 --> 00:02:27,940
and scarcities across our own planet.

47
00:02:27,941 --> 00:02:29,941
The Deep Space Food Challenge.

48
00:02:30,000 --> 00:02:31,310
Pretty big stuff.
