00:00:00.000 --> 00:00:09.000
Intro music.

00:00:09.000 --> 00:00:17.000
The crew of the Space Shuttle Discovery got some recent hands-on experience with equipment they will soon take into space.

00:00:17.000 --> 00:00:26.000
The Return to Flight astronauts were at NASA's Kennedy Space Center in Florida for a Payload Crew Equipment Interface Test.

00:00:26.000 --> 00:00:32.000
This test allows the astronauts to become familiar with equipment for the mission's three spacewalks.

00:00:32.000 --> 00:00:40.000
Among the payloads the astronauts inspected inside the Space Station Processing Facility is the Control Moment Gyroscope

00:00:40.000 --> 00:00:45.000
that they will swap for an inoperable one on the Station during a spacewalk.

00:00:45.000 --> 00:00:50.000
They conducted a fit check on the Thermal Protection System repair sample box

00:00:50.000 --> 00:00:54.000
that contains pieces of the Shuttle's heat-shielding tile.

00:00:54.000 --> 00:00:59.000
These samples will enable the crew to test new repair techniques in space.

00:00:59.000 --> 00:01:07.000
They also inspected the cargo containers installed in the Italian-built Multi-Purpose Logistics Module Raffaello.

00:01:07.000 --> 00:01:16.000
At the nearby SPACEHAB facility, the crew checked out the External Stowage Platform-2 that will carry replacement parts to the Station.

00:01:16.000 --> 00:01:25.000
They will deploy the platform and attach it to the Station's airlock as a permanent spare parts facility.

00:01:25.000 --> 00:01:35.000
The launch window for Space Shuttle Discovery's Return to Flight mission is May 15 to June 3.

00:01:35.000 --> 00:01:40.000
