00:00:00,000 --> 00:00:04,000
The primary structure of NASA’s next flagship

2
00:00:04,000 --> 00:00:08,000
telescope - the Nancy Grace Roman Space telescope

3
00:00:08,000 --> 00:00:12,000
is in the clean room.This marks an

4
00:00:12,000 --> 00:00:16,000
un-official kickoff to the assembly of this widefield telescope.

5
00:00:16,000 --> 00:00:20,000
With the primary structure providing its foundation, Roman will

6
00:00:20,000 --> 00:00:24,000
survey large sweeps of the sky. Unlike the Webb telescope,

7
00:00:24,000 --> 00:00:28,000
which peers with a far narrower focus. These surveys allow

8
00:00:28,000 --> 00:00:32,000
astronomers to understand large scale structures of the Universe

9
00:00:32,000 --> 00:00:36,000
mysterious substances like dark energy and dark matter.

10
00:00:36,000 --> 00:00:40,000
A telescope like this

11
00:00:40,000 --> 00:00:44,000
is assembled bones first, and those bones were

12
00:00:44,000 --> 00:00:48,000
built here at Goddard’s machine shop.

13
00:00:48,000 --> 00:00:52,000
Today we’re preparing to put the spacecraft primary structure onto the skirts.

14
00:00:52,000 --> 00:00:56,000
Next week we’ll be moving the structure and the skirt all the way

15
00:00:56,000 --> 00:01:00,000
up to building 29, up the hill where it will sit on an observatory dolly. 

16
00:01:00,000 --> 00:01:04,000
Roman’s initial construction phase

17
00:01:04,000 --> 00:01:08,000
requires readying these large pieces like the primary structure

18
00:01:08,000 --> 00:01:12,000
which houses critical systems like the propulsion system

19
00:01:12,000 --> 00:01:16,000
its power and attitude control and moving them around like puzzle pieces.

20
00:01:16,000 --> 00:01:20,000
Ready? Heave!

21
00:01:20,000 --> 00:01:24,000
This is the Pantheon.

22
00:01:24,000 --> 00:01:28,000
It’s the scaffolding structure that allows people to easily reach

23
00:01:28,000 --> 00:01:32,000
 the already tall telescope pieces.

24
00:01:32,000 --> 00:01:36,000
And with the platform in position, the cleanroom is finally ready

25
00:01:36,000 --> 00:01:40,000
for the first central piece of hardware.

26
00:01:40,000 --> 00:01:44,000
music

27
00:01:44,000 --> 00:01:48,000
Now that this internal skeleton is

28
00:01:48,000 --> 00:01:52,000
here along with a final hoist,

29
00:01:52,000 --> 00:01:56,000
we can say

30
00:01:56,000 --> 00:02:00,000
that Roman has officially arrived.

31
00:02:00,000 --> 00:02:04,000
music

32
00:02:04,000 --> 00:02:06,656
