Gary Davis: Hello, I'm Gary Davis. I'm on the systems engineering team

4
00:00:12.190 --> 00:00:16.210
for the MMS Mission. MMS is going to study magnetic

5
00:00:16.230 --> 00:00:20.250
reconnection between the Earth and the sun. There's our launch

6
00:00:20.270 --> 00:00:24.280
on our Atlas VI launch vehicle from Cape Canaveral air force station.

7
00:00:24.300 --> 00:00:28.330
Now we are flying above Florida, and the first stage has separated.

8
00:00:28.350 --> 00:00:32.400
The second stage puts us into orbit.

9
00:00:32.420 --> 00:00:36.440
The fairing that protects us during launch will jettison.

10
00:00:36.460 --> 00:00:40.500
And you can see all 4 MMS space craft inside.

11
00:00:40.520 --> 00:00:44.540
Each one gets deployed sequentially

12
00:00:44.560 --> 00:00:48.580
and then you will see the deployments that we have. We have 3 different

13
00:00:48.600 --> 00:00:52.620
types of deployments. The first one is our

14
00:00:52.640 --> 00:00:56.650
magnetometer boom. It is on the underside of the spacecraft.

15
00:00:56.670 --> 00:01:00.690
You'll see the hinge locks open up and then the booms will deploy

16
00:01:00.710 --> 00:01:04.710
one at a time. They have a shoulder joint and an elbow joint, just like

17
00:01:04.730 --> 00:01:08.740
your arm. So, those are our 2 arms opening up.

18
00:01:08.760 --> 00:01:12.780
Our next deployment is the SDP booms. Those are spheres at

19
00:01:12.800 --> 00:01:16.800
the end of 60 meter-long wire cables.

20
00:01:16.820 --> 00:01:20.840
And then our third deployment is along the spin axis of the spacecraft.

21
00:01:20.860 --> 00:01:24.880
You'll see the ADP antennae and the ADP

22
00:01:24.900 --> 00:01:28.910
booms will deploy along the plus and minus Z axis.

23
00:01:28.930 --> 00:01:32.960
And those are all of our deployments.

24
00:01:32.980 --> 00:01:36.980
Each spacecraft has those three instruments that are deployed.

25
00:01:37.000 --> 00:01:41.010
And we have four spacecraft in formation that you'll see in the video.

26
00:01:41.030 --> 00:01:45.030
And we fly in a tetrahedron to get three dimensional

27
00:01:45.050 --> 00:01:49.080
magnetic information.
