Today, we're at NASA Langley Research Center in Hampton, Virginia. 00:00:00
NASA Langley is the oldest of the nine NASA facilities. 00:00:04
Here's another Langley fact. 00:00:07
See this huge structure? 00:00:09
Its original name was the Lunar Landing Research Facility. 00:00:11
But today, we call it the gantry. 00:00:15
In the 1960s, Apollo astronauts trained right here at NASA Langley to land on the moon. 00:00:17
The title of today's show is Measurement, Ratios, and Graphing. 00:00:22
Three, two, one, crash. 00:00:25
And get this, measurement, ratios, and graphs are used every day by NASA researchers. 00:00:27
They make predictions and draw conclusions using the data they collect from their research and extreme tests. 00:00:32
Speaking of graphs, does this look familiar? 00:00:38
Of course, this grid would never fit on your desk. 00:00:42
It's huge. 00:00:45
Each square measures one meter by one meter. 00:00:47
Anyway, NASA researchers use this grid for film analysis. 00:00:52
An aircraft passes in front of the grid and is tracked by a camera. 00:00:56
Then engineers can measure the distance the aircraft travels in a certain amount of time. 00:00:59
NASA engineers analyze this data and make conclusions based on the test results. 00:01:03
Finally, they communicate what they've learned to aircraft companies so they can build safer aircraft. 00:01:07
We'll learn more about how NASA crashes aircraft from this gantry later on in the show. 00:01:12
Right, but first, let's learn more about NASA Langley. 00:01:16
Today's National Aeronautics and Space Administration, or NASA, was established in 1958. 00:01:20
But its historical roots reach back much farther to the early 1900s. 00:01:25
Powered flight was developed by the Wright Brothers in 1903. 00:01:29
However, during World War I, America realized how far it was behind other countries in developing air power. 00:01:32
So, Congress created the NACA, or the National Advisory Committee for Aeronautics. 00:01:38
What is aeronautics? 00:01:43
Aeronautics is simply the science of flight. 00:01:45
The NACA decided to build an aeronautical research facility, and they found the perfect location. 00:01:50
A site was chosen in Hampton, Virginia, and the facility was named the Langley Memorial Aeronautical Laboratory, 00:01:57
after an early aviation pioneer, Samuel Pierpont Langley. 00:02:04
Later, in 1958, Congress changed the name of the NACA to NASA, 00:02:08
and NASA Langley Research Center helped give birth to the space program group. 00:02:13
America's first manned space program, Project Mercury, began at NASA Langley. 00:02:17
Today, NASA has grown to nine centers across the United States that are involved in aeronautics, 00:02:22
earth science, space science, and human exploration of space. 00:02:28
The knowledge gained from NASA research can be found in everyday objects, 00:02:33
like sunglasses, athletic shoes, cordless products, and even the highways we drive on. 00:02:37
So, the next time you fly in an airplane, remember that almost every American aircraft today 00:02:44
uses technology that was developed right here at NASA Langley Research Center. 00:02:49
