Music

2
00:00:08,575 --> 00:00:12,012
We're in the high bay
of building 29 and we have the

3
00:00:12,012 --> 00:00:15,349
vibration facility which is
going to help us test the forces

4
00:00:15,349 --> 00:00:17,951
that we are going to see on
the telescope during our launch 


5
00:00:17,951 --> 00:00:18,852
environment.


6
00:00:18,986 --> 00:00:22,723
OTIS is the combination of the 
Optical Telescope Element

7
00:00:22,723 --> 00:00:25,425
and the Integrated Science
Instrument Module

8
00:00:25,425 --> 00:00:27,427
which basically amounts to the
science portion

9
00:00:27,427 --> 00:00:28,862
of the
JWST Mission.

10
00:00:29,329 --> 00:00:31,598
The telescope is
currently being integrated

11
00:00:31,598 --> 00:00:33,634
in our SSDIF facility

12
00:00:33,634 --> 00:00:38,972
and we will be moving from
the SSDIF facility into our

13
00:00:38,972 --> 00:00:42,676
vibration and acoustic
facilities for testing.

14
00:00:43,076 --> 00:00:46,546
The mechanical engineering team
is preparing by simulating some

15
00:00:46,546 --> 00:00:51,118
of the activities that we will
be doing using a mock up of the

16
00:00:51,118 --> 00:00:54,755
telescope and by practicing
these steps the mechanical

17
00:00:54,755 --> 00:00:58,992
engineering team is making
sure that OTIS is protected from

18
00:00:58,992 --> 00:01:02,763
particles and that its
safeguarded during the test.

19
00:01:02,763 --> 00:01:07,801
So the way we're moving OTIS is
by surrounding the telescope and

20
00:01:07,801 --> 00:01:12,739
OTIS with a tent which is a
four story structure, I-beam

21
00:01:12,739 --> 00:01:16,643
structure that helps protect
OTIS when it's outside the

22
00:01:16,643 --> 00:01:20,147
cleanroom like when we're
doing the tests out here

23
00:01:20,147 --> 00:01:22,583
and basically works like a
shower cap,

24
00:01:22,583 --> 00:01:24,351
it protects the hair
from getting wet.

25
00:01:24,351 --> 00:01:28,055
Here it protects OTIS from
particles and the environment.

26
00:01:28,055 --> 00:01:32,259
Goddard needs to conduct the
sine vibration and acoustic

27
00:01:32,259 --> 00:01:38,398
tests for OTIS primarily so we
can demonstrate and verify that

28
00:01:38,398 --> 00:01:42,369
our mechanical design will
withstand the loads that it will

29
00:01:42,369 --> 00:01:45,539
see when it launched
on the Ariane 5 Rocket.

30
00:01:46,006 --> 00:01:49,810
We do these pre-tests as a
strength qualifier, workmanship,

31
00:01:49,810 --> 00:01:52,679
make sure everything has been
put together, an our analysis is

32
00:01:52,679 --> 00:01:56,516
right and we don't send anything
to launch that will potentially

33
00:01:56,516 --> 00:01:58,785
break during launch.

34
00:01:58,785 --> 00:02:00,387
