NASA is counting down to the second attempt to launch space shuttle Endeavour on an 11-day Earth radar mapping mission. Images: NASA TV/Spaceflight Now.

Sunrise Dawn breaks along Florida's central Atlantic coastline today as Endeavour's countdown enters its final hours.
All fueled up Endeavour stands fully fueled atop launch pad 39A. Loading of a half-million gallons of super-cold cryogenics occurred before sunrise.
A bit of ice The Final Inspection Team was dispatched to the launch pad after fueling to look for ice or debris on the shuttle and pad structures. The team noted some frost on the backside of the external tank as seen here.
Judging sizes The ice team members look so very tiny standing near the tail of Endeavour.
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.
Looking up An engineering camera at launch pad 39A gives an interesting view looking up to the pad surface.
A haze day Unlike the first launch attempt of STS-99, weather will not be a factor in deciding whether to launch Endeavour. There is haze around KSC but it won't be a problem.
