1
00:00:04,800 --> 00:00:06,600
Four German teachers flew

2
00:00:06,610 --> 00:00:11,900
aboard NASA's Stratospheric Observatory
For Infrared Astronomy in early 2014 as

3
00:00:11,900 --> 00:00:14,180
part of a German Airborne Astronomy

4
00:00:14,180 --> 00:00:17,000
Ambassadors Program.

5
00:00:20,180 --> 00:00:24,000
The teachers and their German SOFIA
Institute escort interfaced with German

6
00:00:24,000 --> 00:00:27,400
and American scientists on the GREAT
Spectrometer team

7
00:00:27,400 --> 00:00:31,500
as the flying observatory became a flying
classroom for the night.

8
00:00:36,780 --> 00:00:38,019
The German Receiver for

9
00:00:38,019 --> 00:00:41,769
Astronomy at Terahertz Frequencies, or
GREAT, Spectrometer,

10
00:00:41,769 --> 00:00:45,600
is a special instrument added to SOFIA's telescope on certain flights,

11
00:00:45,600 --> 00:00:49,129
and it showed the teachers how the
analysis of infrared light from

12
00:00:49,129 --> 00:00:51,500
distant objects in space can illustrate

13
00:00:51,500 --> 00:00:55,000
what elements those objects are made of.

14
00:00:59,000 --> 00:01:02,870
This first group of German educators
took their experience back to their
