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