How does the Remote Manipulator System work on the Space Shuttle?

00:00:17.000 --> 00:00:24.000
The Remote Manipulator System is made for us by our friends in Canada, and we use that in the Space Shuttle for a lot of varied things.

00:00:24.000 --> 00:00:31.000
We can use it to grab and deploy satellites, or as well as to give astronauts an access platform or a work platform when

00:00:31.000 --> 00:00:33.000
they're doing work somewhere inside the orbiter.

00:00:33.000 --> 00:00:39.000
Now what you'll see when we open the payload bay doors in the orbiter, there on the port side will be the Canadian robot arm,

00:00:39.000 --> 00:00:45.000
and it has a shoulder and an elbow and a wrist, and it can move in all those joints. And what we'll do is we deploy it up,

00:00:45.000 --> 00:00:51.000
we can grab a payload that's sitting in the payload bay and set it up above the orbiter, let go and leave it up in space.

00:00:51.000 --> 00:00:56.000
Or we can grab a satellite that's already up there with the robot arm and bring it down and

00:00:56.000 --> 00:01:01.000
sit it in the payload bay and work on it there, such as the Hubble Space Telescope has been done a couple of times.

00:01:01.000 --> 00:01:08.000
Now over on the starboard side of the orbiter is the Orbiter Boom Sensor System, or the OBSS, as we call it.

00:01:08.000 --> 00:01:13.000
It looks a lot like the robot arm but it doesn't have any moving joints like the RMS does.

00:01:13.000 --> 00:01:17.000
What you'll see when we get up on orbit is that the RMS will actually lift up out of its cradle.

00:01:17.000 --> 00:01:22.000
It will reach over and grab the OBSS, pick it up and then use it to do inspections of the

00:01:22.000 --> 00:01:27.000
tile on the bottom side of the orbiter, as well as the leading-edge Reinforced Carbon-Carbon (or RCC) panels.

00:01:27.000 --> 00:01:32.000
And that is how we use the RMS and the OBSS on the Shuttle.

00:01:32.000 --> 00:01:41.000
Music.
