EO-1/SAC-C Launched November 21 18:24:25.429 GMT
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 launched on schedule Tuesday, Nov. 21 launch at 10:24 a.m. PST (1:24 p. m. EST) from NASA's Space Launch Complex 2 at Vandenberg Air Force Base, CA.
EO-1 will provide on-orbit demonstration and validation of several subsystem technologies that will enable NASA to transitition to a series of smaller and lighter Earth Observation spacecrafts. EO-1 will contain an X-Band Phased Array Antenna, a lightweight flexible solar array, a pulse plasma thruster, enhanced formation flying, a Carbon-Carbon radiator and a new wideband advanced recorder/processor.
SAC-C will provide multispectral imaging of terrestrial and coastal environments. The spacecraft will provide studies of the structure and dynamics of the Earth's atmosphere and ionosphere. The Earth's geomagnetic field will also be studied. SAC-C will seek to measure the space radiation in the environment and its influence on advanced electronic components. Also, the satellite will determine the migration route of the Franca whale. Lastly, SAC-C will verify autonomous methods of attitude and orbit determination.
The launch was originally scheduled for November 18 but was rescheduled to give NASA and Boeing engineers time 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.
