1
00:00:05,349 --> 00:00:02,790
a tanking test is where the launch team

2
00:00:06,869 --> 00:00:05,359
loads about 535 000 gallons of liquid

3
00:00:08,790 --> 00:00:06,879
hydrogen and liquid oxygen into

4
00:00:11,669 --> 00:00:08,800
discovery's external fuel tank just as

5
00:00:13,030 --> 00:00:11,679
it would be done for real launch attempt

6
00:00:14,950 --> 00:00:13,040
and the various parts of the tank are

7
00:00:17,269 --> 00:00:14,960
closely monitored and data is going to

8
00:00:19,189 --> 00:00:17,279
be recorded filling the tank is a

9
00:00:21,510 --> 00:00:19,199
procedure known as tanking and takes

10
00:00:23,109 --> 00:00:21,520
about three hours to fill the 154 foot

11
00:02:24,710 --> 00:00:23,119
tall external tank with the two super

12
00:02:27,910 --> 00:02:26,070
tank's dry

13
00:02:30,070 --> 00:02:27,920
so the frost balls we got probably won't

14
00:02:31,509 --> 00:02:30,080
wash away at least not until it warms up

15
00:02:34,229 --> 00:02:31,519
significantly and you know if we get a

16
00:02:36,550 --> 00:02:34,239
little moisture on the tank

17
00:02:38,150 --> 00:02:36,560
and then later we'll uh

18
00:02:40,949 --> 00:02:38,160
we'll be moving the camera over in front

19
00:02:44,070 --> 00:02:42,790
yeah we'll be moving the whole assembly

20
00:02:47,190 --> 00:02:44,080
but he'll come back and give me a hand

21
00:02:51,990 --> 00:02:48,790
entity final inspection team on direct

22
00:02:57,270 --> 00:02:54,470
and final inspection team this thing is

23
00:02:59,270 --> 00:02:57,280
seven i've got you live clear help me

24
00:03:01,830 --> 00:02:59,280
i've got you loud and clear and i want

25
00:03:03,030 --> 00:03:01,840
to tell you that we're assembled and

26
00:03:05,030 --> 00:03:03,040
we've done our

27
00:03:07,350 --> 00:03:05,040
pre-test safety briefing

28
00:03:29,910 --> 00:03:07,360
and we're ready to go to the pad when

29
00:03:29,920 --> 00:03:51,509
your cold
