Hi, I'm Cory with another NASA fact.

2
00:00:07,000 --> 00:00:09,000
What is nanotechnology?

3
00:00:09,000 --> 00:00:11,000
Nano what-ology?

4
00:00:11,000 --> 00:00:16,000
Nanotechnology. NASA is studying how to make things the size of atoms.

5
00:00:16,000 --> 00:00:18,000
Wow, how small is that?

6
00:00:18,000 --> 00:00:21,000
Nano is the prefix for one billion.

7
00:00:21,000 --> 00:00:26,000
A hundred nanometers is still a thousand times smaller than the diameter of a human hair.

8
00:00:26,000 --> 00:00:28,000
Why would we need things that small?

9
00:00:28,000 --> 00:00:30,000
The smaller the computer parts, the better they work.

10
00:00:30,000 --> 00:00:36,000
We could then make little nanorobots that could be programmed to fix things we can't easily see or reach.

11
00:00:36,000 --> 00:00:39,000
Some scientists think they could even help repair the ozone layer.

12
00:00:39,000 --> 00:00:41,000
Can nanotechnology shrink people?

13
00:00:41,000 --> 00:00:48,000
No, but someday we might be able to send nanorobots inside a person to search out and destroy bad cells like cancer.

14
00:00:48,000 --> 00:00:51,000

Until next time, I'm Cory with another cool NASA fact.
