00:00:03,936 --> 00:00:05,571
>>Jane Houston Jones:
What's Up for March.

3
00:00:05,571 --> 00:00:09,375
Jupiter, its moons
and moon shadows.

4
00:00:09,375 --> 00:00:10,176
Hello and welcome.

5
00:00:10,176 --> 00:00:11,644
I'm Jane Houston
Jones from NASA's

6
00:00:11,644 --> 00:00:15,215
Jet Propulsion Laboratory
in Pasadena, California.

7
00:00:15,381 --> 00:00:17,717
Jupiter dominates the
evening sky this month,

8
00:00:17,717 --> 00:00:20,987
rising at sunset
and setting at dawn.

9
00:00:20,987 --> 00:00:24,023
On March 8th Jupiter reaches
what is called ‘opposition.'

10
00:00:24,023 --> 00:00:28,661
Imagine that Jupiter and the
sun are on opposite ends

11
00:00:28,661 --> 00:00:31,831
of a straight line
with Earth in between.

12
00:00:31,831 --> 00:00:34,767
This brings Jupiter
its closest to Earth,

13
00:00:34,767 --> 00:00:38,538
so it shines brighter and
appears larger in telescopes.

14
00:00:38,538 --> 00:00:41,574
On the nights of
March 14th and 15th,

15
00:00:41,574 --> 00:00:45,878
March 21st and 22nd
and March 29th two of

16
00:00:45,878 --> 00:00:49,349
Jupiter's moons will
cross the planet's disk.

17
00:00:50,883 --> 00:00:52,852
When the planet is
at opposition and

18
00:00:52,852 --> 00:00:55,422
the sun shines on
Jupiter's moons,

19
00:00:57,557 --> 00:01:00,593
we can see the moons'
shadows crossing the planet.

20
00:01:03,529 --> 00:01:04,797
There are actually eleven of

21
00:01:04,797 --> 00:01:06,399
these double shadow transits

22
00:01:06,399 --> 00:01:09,035
in March.

23
00:01:09,035 --> 00:01:11,938
The next 6 months will be
awesome times for you to

24
00:01:11,938 --> 00:01:14,974
image Jupiter when it's
highest in the sky━

25
00:01:14,974 --> 00:01:18,544
near midnight now and a
little earlier each night

26
00:01:18,544 --> 00:01:19,779
through the late summer.

27
00:01:19,779 --> 00:01:22,782
Even through the smallest
telescopes or binoculars

28
00:01:22,782 --> 00:01:25,718
you should be able to see the
two prominent belts

29
00:01:25,718 --> 00:01:27,954
on each side of
Jupiter's equator,

30
00:01:27,954 --> 00:01:32,992
the four Galilean moons: Io,
Europa, Ganymede and Callisto,

31
00:01:32,992 --> 00:01:36,596
and with some difficulty
Jupiter's Red Spot,

32
00:01:36,596 --> 00:01:38,431
when it's facing Earth.

33
00:01:38,431 --> 00:01:39,332
[WHOOSH]

34
00:01:40,533 --> 00:01:43,069
NASA's Juno spacecraft will
arrive at Jupiter on July 4th

35
00:01:43,069 --> 00:01:46,906
of this year and go into orbit
around the giant planet.

36
00:01:46,906 --> 00:01:50,810
Right now the Juno mission
science team is actively seeking

37
00:01:50,810 --> 00:01:53,813
amateur and professional
images of the planet.

38
00:01:53,813 --> 00:01:57,083
These images are
uploaded to a Juno website,

39
00:01:57,083 --> 00:02:00,686
and the public is invited to
discuss points of interest

40
00:02:00,686 --> 00:02:02,555
in Jupiter's atmosphere.

41
00:02:02,555 --> 00:02:04,891
Locations will
later be voted on.

42
00:02:04,891 --> 00:02:06,592
The favorites will
be targets for

43
00:02:06,592 --> 00:02:09,896
JunoCam, the spacecraft's
imaging camera.

44
00:02:09,896 --> 00:02:11,831
Once JunoCam has
taken the images,

45
00:02:11,831 --> 00:02:14,800
they'll be posted online.

46
00:02:14,800 --> 00:02:17,036
Imaging participants
can then process these

47
00:02:17,036 --> 00:02:21,707
raw mission images and re-upload
them for others to view.

48
00:02:21,707 --> 00:02:24,477
