This is home movies at their finest. Astronaut Mike Massimino takes us inside the garage of space shuttle Discovery -- also known as the Orbiter Processing Facility (OPF)-- for a behind the scenes look at the work that is done on the orbiters, as well as seeing some of the training for the astronauts on the upcoming STS-131 mission. This is part of a series of "behind the scenes for STS-131" videos that Massimino hosts, which you can find on the
NASA TV You Tube channel
. Mass brings humor and sense of wonder to these videos, and is great at doing public outreach for NASA.
