VANDENBERG AIR FORCE BASE, CA – The launch of a Boeing Delta II rocket carrying NASA’s Earth Observing 1 satellite and the Argentine
Commission on Space Activities satellite, SAC-C, has been rescheduled to occur no earlier than Monday, Nov. 20 at 10:24 a.m. PST from Space
Launch Complex-2.

NASA and Boeing engineers plan to resolve discrepancies in the review of the pedigree paper from the redundant inertial flight control assembly.
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 Earth Observing 1 satellite’s primary focus is to develop and test a set of advanced technology land imaging instruments. Argentina’s SAC-C
satellite is designed to study the structure and dynamics of the Earth’s atmosphere, ionosphere and geomagnetic field.

media who want to cover this event should arrive at the South Base Gate no later that 10:30 a.m. Remote camera set-up will follow the press
