The launch of NASA’s Comet Nucleus Tour (CONTOUR) spacecraft is
scheduled for Monday, July 1. The launch window is 2:56:14 – 2:56:20 a.m.
EDT. Liftoff will occur aboard a Delta II launch vehicle from Pad A at
Space Launch Complex 17, Cape Canaveral Air Force Station. Should launch be
delayed, the next opportunity is July 3 from 2:47:41 – 2:47:47 a.m. EDT.

CONTOUR is our first detailed look into the heart of a comet – its nucleus.
The spacecraft will fly as close as 62 miles (100 kilometers) from at least
two comets, taking the sharpest pictures yet of the nucleus while analyzing
the gas and dust that surround these rocky, icy building blocks of the solar
system. For the first time, CONTOUR will help us assess the diversity of
comets and unravel the mysteries of how they evolve.

CONTOUR was built and will be controlled after launch by the Applied Physics
Laboratory of Johns Hopkins University.

The Delta II launch vehicle and its associated launch support services are
from The Boeing Company. NASA’s John F. Kennedy Space Center is responsible
for the launch countdown management and launch vehicle engineering
