Morning vapors
As dawn breaks on a very moist and foggy Florida morning, vapors from Endeavour's main engines and the external tank seem to wrap around the shuttle to create a dramatic view.
Checking the pad
The Final Inspection Team was dispatched to the launch pad after fueling to look for ice or debris on the shuttle and launch pad structures. Two members of the team are seen here near the base of the solid rocket boosters.

Little people
Members of the inspection team stand on the mobile launch platform to examine Endeavour's three main engines.

A critical link
A launch pad camera shows the 17-inch quick disconnect umbilicals between the orange external fuel tank and the belly of Endeavour. The umbilicals are the passage way of fuel between the shuttle and tank.
The power end
The bottom of space shuttle Endeavour atop the mobile launcher platform is seen through another launch pad camera.
Having a meal
Endeavour's astronauts are seated for what should be their final meal on Earth before beginning an 11-day journey in space.

Heading to pad
The six shuttle astronauts depart their quarters at Kennedy Space Center's Operations & Checkout Building for the ride to pad 39A.
All aboard
All six astronauts entered Endeavour fairly quickly today, allowing the crew module's hatch to be closed earlier than scheduled.
