| [00:00:08.16] | Gary Davis: Hello, I'm Gary Davis. I'm on the systems engineering team |
| [00:00:12.19] | for the MMS Mission. MMS is going to study magnetic |
| [00:00:16.23] | reconnection between the Earth and the sun. There's our launch |
| [00:00:20.27] | on our Atlas VI launch vehicle from Cape Canaveral air force station. |
| [00:00:24.30] | Now we are flying above Florida, and the first stage has separated. |
| [00:00:28.35] | The second stage puts us into orbit. |
| [00:00:32.42] | The fairing that protects us during launch will jettison. |
| [00:00:36.46] | And you can see all 4 MMS space craft inside. |
| [00:00:40.52] | Each one gets deployed sequentially |
| [00:00:44.56] | and then you will see the deployments that we have. We have 3 different |
| [00:00:48.60] | types of deployments. The first one is our |
| [00:00:52.64] | magnetometer boom. It is on the underside of the spacecraft. |
| [00:00:56.67] | You'll see the hinge locks open up and then the booms will deploy |
| [00:01:00.71] | one at a time. They have a shoulder joint and an elbow joint, just like |
| [00:01:04.73] | your arm. So, those are our 2 arms opening up. |
| [00:01:08.76] | Our next deployment is the SDP booms. Those are spheres at |
| [00:01:12.80] | the end of 60 meter-long wire cables. |
| [00:01:16.82] | And then our third deployment is along the spin axis of the spacecraft. |
| [00:01:20.86] | You'll see the ADP antennae and the ADP |
| [00:01:24.90] | booms will deploy along the plus and minus Z axis. |
| [00:01:28.93] | And those are all of our deployments. |
| [00:01:32.98] | Each spacecraft has those three instruments that are deployed. |
| [00:01:37.00] | And we have four spacecraft in formation that you'll see in the video. |
| [00:01:41.03] | And we fly in a tetrahedron to get three dimensional |
| [00:01:45.05] | magnetic information. |
