00:00:00,000 --> 00:00:05,990
you

2
00:00:12,150 --> 00:00:08,550
mysterious Jupiter is the most massive

3
00:00:14,400 --> 00:00:12,160
planet in our solar system now NASA is

4
00:00:16,590 --> 00:00:14,410
preparing to send the pioneering Juno

5
00:00:19,560 --> 00:00:16,600
spacecraft on a one-year mission to

6
00:00:22,670 --> 00:00:19,570
study the stormy gas giant its mission

7
00:00:26,100 --> 00:00:22,680
to study Jupiter's core atmosphere

8
00:00:28,260 --> 00:00:26,110
powerful magnetic field and Aurora's all

9
00:00:31,890 --> 00:00:28,270
in hopes of expanding our knowledge of

10
00:00:33,990 --> 00:00:31,900
how our solar system formed Juno is

11
00:00:36,360 --> 00:00:34,000
launching from space launch complex 41

12
00:00:39,560 --> 00:00:36,370
at Cape Canaveral Air Force Station in

13
00:00:42,960 --> 00:00:39,570
Florida aboard a mighty Atlas 5 rocket

14
00:00:46,350 --> 00:00:42,970
the spacecraft arrived in Florida inside

15
00:00:49,709 --> 00:00:46,360
a US Air Force c-17 cargo plane touching

16
00:00:52,310 --> 00:00:49,719
down April 8 2011 on the shuttle landing

17
00:00:55,500 --> 00:00:52,320
facility at nearby Kennedy Space Center

18
00:00:58,020 --> 00:00:55,510
from there juna was moved to the high

19
00:01:00,479 --> 00:00:58,030
bay at Astro tech space operations in

20
00:01:03,630 --> 00:01:00,489
Titusville or technicians rented at for

21
00:01:06,600 --> 00:01:03,640
launch several critical pieces had to be

22
00:01:09,779 --> 00:01:06,610
installed including a high-gain antenna

23
00:01:12,600 --> 00:01:09,789
used for communications and all three

24
00:01:14,460 --> 00:01:12,610
power producing solar arrays which also

25
00:01:17,520 --> 00:01:14,470
were deployed and put through

26
00:01:19,710 --> 00:01:17,530
illumination testing as Juno was

27
00:01:22,109 --> 00:01:19,720
prepared for liftoff elements of the

28
00:01:24,150 --> 00:01:22,119
Atlas 5 launch vehicle built by United

29
00:01:26,999 --> 00:01:24,160
Launch Alliance began arriving May

30
00:01:29,100 --> 00:01:27,009
twenty-third the booster stage arrived

31
00:01:31,499 --> 00:01:29,110
at Cape Canaveral Air Force Station skid

32
00:01:34,650 --> 00:01:31,509
strip aboard a Russian Antonov cargo

33
00:01:38,160 --> 00:01:34,660
aircraft two days later the Centaur

34
00:01:40,499 --> 00:01:38,170
upper stage followed the Atlas 5 booster

35
00:01:42,180 --> 00:01:40,509
was hoisted into liftoff position inside

36
00:01:44,930 --> 00:01:42,190
the launch complexes vertical

37
00:01:47,910 --> 00:01:44,940
integration facility on june thirteenth

38
00:01:49,890 --> 00:01:47,920
then the Rockets five solid rocket

39
00:01:52,080 --> 00:01:49,900
boosters were attached

40
00:01:55,740 --> 00:01:52,090
the rocket centaur upper stage arrived

41
00:01:58,230 --> 00:01:55,750
at the launch pad jun 24th but before

42
00:02:01,200 --> 00:01:58,240
juno could join its rocket it had to

43
00:02:04,320 --> 00:02:01,210
pass the spin test a final check of its

44
00:02:06,870 --> 00:02:04,330
weight and balance Juno was deemed ready

45
00:02:08,760 --> 00:02:06,880
to fly then placed into the two-piece

46
00:02:10,770 --> 00:02:08,770
payload fairing that will protect the

47
00:02:14,040 --> 00:02:10,780
spacecraft during the first three and a

48
00:02:16,830 --> 00:02:14,050
half minutes of the climb to space early

49
00:02:18,540 --> 00:02:16,840
in the morning of July 27th the fairing

50
00:02:21,150 --> 00:02:18,550
containing NASA's newest and her

51
00:02:23,490 --> 00:02:21,160
planetary Explorer arrived at space

52
00:02:26,730 --> 00:02:23,500
launch complex 41 where it awaits
