McLEAN, Va., Oct. 18, 2000 – A Lockheed Martin Astronautics Atlas IIA rocket is being readied at Cape Canaveral Air Station (CCAS), Fla., to launch the eighth spacecraft for the Defense Satellite Communications System III (DSCS III) program under contract to the U.S. Air Force. The launch window opens at 7:36p.m. EDT and extends 79 minutes to 8:55 p.m.
This is the seventh of eight Atlas launches planned by International Launch Services (ILS) for CCAS this year. AC-140, the Atlas IIA vehicle used for this mission, will launch the DSCS B11 satellite into a geosynchronous transfer orbit. The satellite will reach its final orbital position at 95 degrees East longitude by use of its on-board propulsion system. All previous seven launches of DSCS III spacecraft on Atlas were successful, dating back to the first DSCS III launch in February 1992. The Atlas family has achieved 52 consecutive, successful flights and the Atlas II series has a 100% mission success.
The DSCS III B11 spacecraft, built by Lockheed Martin Missiles & Space, is the second of four super high-frequency communications satellites to feature Service Life Enhancement Program upgrades. These upgrades will provide improved uninterrupted secure voice and high data rate communications to its Department of Defense national security users. Missiles & Space will supply two more of these satellites to the U.S. Air Force Space and Missile Systems Center, Los Angeles Air Force Base, CA.
The launch may be viewed live at:
Time: 6 :45p.m.EDT
Satellite: Galaxy 3 Transponder 23
Satellite Location: 95 Degrees
Down Link Frequency: 4160 MHZ C-band
