1
00:00:09,650 --> 00:00:07,460
well NASA has a long history using

2
00:00:11,660 --> 00:00:09,660
barges but specifically Pegasus was

3
00:00:13,850 --> 00:00:11,670
built to support the transportation of

4
00:00:16,189 --> 00:00:13,860
the external tank for shuttle from

5
00:00:18,890 --> 00:00:16,199
Massoud assembly facility over to

6
00:00:22,670 --> 00:00:18,900
Kennedy Space Center the NASA Pegasus

7
00:00:25,189 --> 00:00:22,680
barge is a NASA asset we've had it since

8
00:00:26,720 --> 00:00:25,199
about the year 2000 when the

9
00:00:29,240 --> 00:00:26,730
requirements first came down from the

10
00:00:31,310 --> 00:00:29,250
Space Launch System and the big core

11
00:00:32,780 --> 00:00:31,320
stage it was obvious that we had to do

12
00:00:35,479 --> 00:00:32,790
something with our barge should be able

13
00:00:38,360 --> 00:00:35,489
to transport it so we've had to actually

14
00:00:41,150 --> 00:00:38,370
extend the barge by 50 feet because of

15
00:00:43,369 --> 00:00:41,160
the added weight and added length of the

16
00:00:44,990 --> 00:00:43,379
course stage over the external tank so

17
00:00:47,299 --> 00:00:45,000
we we've really saved about eight

18
00:00:49,700 --> 00:00:47,309
million dollars modifying the current

19
00:00:52,420 --> 00:00:49,710
barge versus going out and building a

20
00:00:55,939 --> 00:00:52,430
brand new barge Pegasus came to us

21
00:00:58,279 --> 00:00:55,949
needing to be lengthened we fabricated a

22
00:01:00,619 --> 00:00:58,289
hundred and sixty-five foot long plug

23
00:01:03,410 --> 00:01:00,629
section for the middle of the vessel we

24
00:01:06,140 --> 00:01:03,420
had the vessel retrieved two at our

25
00:01:07,940 --> 00:01:06,150
facility we put it up on JA dock we cut

26
00:01:10,280 --> 00:01:07,950
the vessel in half inserted the new

27
00:01:13,700 --> 00:01:10,290
section removed an old section and

28
00:01:15,679 --> 00:01:13,710
reattached all and all the structural

29
00:01:18,710 --> 00:01:15,689
systems all the mechanical systems all

30
00:01:20,960 --> 00:01:18,720
the electrical systems upgraded some of

31
00:01:24,260 --> 00:01:20,970
the generator power the switchboards

32
00:01:26,179 --> 00:01:24,270
main control centers so if we've we've

33
00:01:28,520 --> 00:01:26,189
done quite a bit of work to it so it's

34
00:01:31,670 --> 00:01:28,530
mission for the SLS core stage will be

35
00:01:34,010 --> 00:01:31,680
very similar shipping routes the way

36
00:01:37,429 --> 00:01:34,020
that we you know installed the the cargo

37
00:01:39,469 --> 00:01:37,439
all that is very similar to the external

38
00:01:41,420 --> 00:01:39,479
tank so we have the experience and the

39
00:01:44,690 --> 00:01:41,430
database to help us for with the core

40
00:01:46,670 --> 00:01:44,700
stage in modifying Pegasus we had to

41
00:01:48,590 --> 00:01:46,680
deal with a significant way to increase

42
00:01:49,999 --> 00:01:48,600
the external tank system weight

43
00:01:52,910 --> 00:01:50,009
approximately one hundred and thirty six

44
00:01:54,469 --> 00:01:52,920
thousand pounds for SLS core stage we

45
00:01:57,170 --> 00:01:54,479
have to accommodate approximately eight

46
00:01:59,480 --> 00:01:57,180
hundred thousand pounds and in fact it's
