EXPENDABLE LAUNCH VEHICLE STATUS REPORT

Spacecraft: NPP (NPOESS Preparatory Project)
Launch Vehicle: Delta II 7920
Launch Site: Vandenberg Air Force Base, Calif.
Launch Pad: Space Launch Complex 2
Launch Date: Oct. 28, 2011
Launch Window: 2:48:01 a.m. - 2:57:11 a.m. PDT (9 min., 10 sec.)
Orbital Altitude: 512 miles

The launch of the NPOESS Preparatory Project (NPP) spacecraft aboard a
United Launch Alliance Delta II rocket from Vandenberg Air Force Base
has been retargeted for Friday, Oct. 28. The postponement for at
least 24 hours will allow time to complete the necessary engineering
review before the payload fairing is installed around the spacecraft.

The launch window on Oct. 28 is unchanged and extends from 2:48:01
a.m. - 2:57:11 a.m. PDT.

NPP represents a critical first step in building the next-generation
of Earth-observing satellites. NPP will carry the first of the new
sensors developed for this satellite fleet, now known as the Joint
Polar Satellite System (JPSS), to be launched in 2016. NPP is the
bridge between NASA's Earth Observing System (EOS) satellites and the
forthcoming series of JPSS satellites. The mission will test key
technologies and instruments for the JPSS missions.
