00:00:00.000 --> 00:00:10.000
Intro music.

00:00:10.000 --> 00:00:16.000
Lisa Campbell is willing to crawl on her hands and knees to help with the Return to Flight effort.

00:00:16.000 --> 00:00:20.000
As an aerospace technician with United Space Alliance,

00:00:20.000 --> 00:00:27.000
she spends up to 10 hours a day installing temperature sensors inside Space Shuttle Discovery's left wing.

00:00:27.000 --> 00:00:34.000
The sensors are part of a new safety measure called the Wing Leading Edge Impact Detection System.

00:00:34.000 --> 00:00:36.000
On all future Space Shuttle flights,

00:00:36.000 --> 00:00:46.000
22 temperature sensors and 66 accelerometers will monitor each wing during launch and throughout the mission.

00:00:46.000 --> 00:00:50.000
They'll collect data and quickly transmit it back to Earth.

00:00:50.000 --> 00:00:58.000
Instead of wiring and installing each sensor individually, Campbell's team is completing the work in three phases.

00:00:58.000 --> 00:01:01.000
As she crawls through the wing to reach the leading edge,

00:01:01.000 --> 00:01:08.000
Campbell has to dodge parts of the orbiter's airframe and maneuver through increasingly small spaces.

00:01:08.000 --> 00:01:12.000
She even has to bring a light and equipment along, too.

00:01:12.000 --> 00:01:14.000
But despite the cramped conditions,

00:01:14.000 --> 00:01:25.000
Campbell loves her work and the opportunity to see Space Shuttle Discovery from an unusual perspective.

00:01:25.000 --> 00:01:30.000
