The launch of the Jason 1 and Timed satellites aboard a
Boeing Delta II rocket is scheduled to occur on Friday, Dec. 7
from NASA’s Space Launch Complex 2 at Vandenberg Air Force
Base, Calif. The 20-minute launch window extends from 6:58 to
7:18 a.m. PST. The target launch time is 7:07 a.m. PST.

Jason 1 is a joint U.S./French oceanography mission. The
spacecraft will build on the heritage of the venerable
Topex/Poseidon satellite in continuing observations of the
global climate interaction occurring between the sea and the
atmosphere. Jason 1 will monitor world ocean circulation,
study interactions of the oceans and atmosphere, improve
climate predictions and observe events such as El Nino. The
project is managed by the Jet Propulsion Laboratory, Pasadena,
Calif., for NASA and the French space agency.

NASA’s Timed spacecraft will conduct the first global
study of a critical region of Earth’s atmosphere, known as the
mesosphere, lower thermosphere and ionosphere. The two-year
mission will study the influences of the sun as well as humans
on this least explored and understood region located between
40 to 110 miles (60 to 180 kilometers) above the Earth’s
surface. Data provided by Timed will improve our
understanding of this “gateway region” and its effects on
satellites, communications, and spacecraft re-entering the
Earth’s atmosphere. Timed is a NASA satellite managed by the
Goddard Space Flight Center, Greenbelt, Md.
