NOTE TO EDITORS/NEWS DIRECTORS

EO-1/SAC-C LAUNCH DELAYED TO MONDAY NOV. 20

The launch of NASA's Earth Observing 1 (EO-1) satellite and the SAC-C spacecraft for the Argentine Commission on Space Activities aboard a Boeing Delta II rocket has been rescheduled to occur no earlier than Monday, Nov. 20 at 10:24 a.m. PST from NASA's Space Launch Complex 2 at Vandenberg Air Force Base, CA.

NASA and Boeing engineers plan to resolve discrepancies in the review of the pedigree paper from the redundant inertial flight control assembly (RIFCA). The RIFCA is the guidance computer on board the Delta II vehicle.

Managers determined there is insufficient time to perform the independent review of the pedigree paper, therefore the launch was postponed 24 hours.

The prelaunch press conference has also been rescheduled and will now occur on Sunday, Nov. 19 at 11 a.m. PST. from Vandenberg.
