you

7
00:03:19,990 --> 00:05:24,870
right

8

you

00:06:04,690 --> 00:06:02,740
New Year's Eve the Grail a spacecraft

10
00:06:06,790 --> 00:06:04,700
was going to be sent into orbit around

11
00:06:08,200 --> 00:06:06,800
the moon all right we're going to go

12
00:06:11,980 --> 00:06:08,210
through the South Pole of the moon and

13
00:06:14,560 --> 00:06:11,990
do about a 38 minute burn 38-minute

14
00:06:15,880 --> 00:06:14,570
maneuver to slow the spacecraft down

15
00:06:18,370 --> 00:06:15,890
enough so this is going to go into orbit

16
00:06:19,720 --> 00:06:18,380
around moon it's not really going to be

17
00:06:21,880 --> 00:06:19,730
nailed by the tents because we've

18
00:06:23,680 --> 00:06:21,890
practiced it a lot and a lot of testing

19
00:06:26,590 --> 00:06:23,690
but it's going to be a long time the

20
00:06:28,330 --> 00:06:26,600
maneuver takes 38 minutes and so we just

21
00:06:30,220 --> 00:06:28,340
have to have a lot of patience and we'll

22
00:06:32,740 --> 00:06:30,230
be able to monitor the progress the

23
00:06:34,870 --> 00:06:32,750
whole time through the event we have to

24
00:06:37,060 --> 00:06:34,880
do it twice because the grill a will go

25
00:06:39,370 --> 00:06:37,070
into orbit on New Year's Eve but Grail

26
00:06:41,980 --> 00:06:39,380
be the second spacecraft will go into

27
00:06:43,690 --> 00:06:41,990
orbit on new year's day so we repeat

28
00:06:46,150 --> 00:06:43,700
basically the same process to do that

29
00:06:49,300 --> 00:06:46,160
again another burn of around 38 minutes

30
00:06:55,950 --> 00:06:49,310
39 minutes and then the size of maneuver

31
00:07:01,499 --> 00:06:58,879
the purpose of the Grail mission is to

32
00:07:04,080 --> 00:07:01,509
gather data on the gravity of the moon

33
00:07:07,260 --> 00:07:04,090
and then the scientists use that gravity
