    Hi:
    
    There is some confusion over the Minotaur/JAWSAT launch window and launch time.
    Normally launch occurs at the start of the window. This launch is different...
    it is planned for 10 minutes after the window opens. Refer to attached info.
    
    Regards,

    			     Missile Launch Friday
    				       
    A Minotaur missile is scheduled for launch from Vandenberg AFB on Friday
    evening, January 14th. The Minotaur is scheduled to leave pad SLC-7 at 19:04
    PST, head towards the southwest, and place several small satellites into a polar
    orbit. The launch window runs from 18:54 to 21:54 PST.
    
    If the weather is favorable, the launch should be visible for at least 200
    miles.
    
    --------------------------------------------------------------------------------
    
    			      Vandenberg Launch Net
    
    If the weather is clear Friday evening, ham radio operators in southern
    California are planning on running a Vandenberg Launch Net to pass along
    Minotaur countdown status and discuss the launch.
    
    The net will be convened at 18:30 PST on the 147.000 MHz Santa Barbara repeater
    (131.8 Hz PL, +600 KHz offset).

    	(The following is an Air Force news release about the launch)
    
    SPACE & MISSILE SYSTEMS CENTER (AFMC)                           
    Office of Public Affairs
    Air Force Minuteman Set to be First Launch of New Millennium
    
    LOS ANGELES AIR FORCE BASE, Calif., - For the first time ever, the Air Force
    will use a refurbished Minuteman II rocket motor combined with Pegasus XL upper
    stages to launch satellites into orbit Jan 14, expected to be the world's first
    space launch of the millennium.  The famed Minuteman II rocket, deactivated as
    an offensive weapon system by Strategic Arms Reduction Treaty in 1991, was
    initially designed as an Inter-Continental Ballistic Missiles delivery system.
    
    Liftoff from Vandenberg Air Force Base, Calif., is set for 7:04 p.m. PST.
    
    The Orbital Suborbital Program Space Launch Vehicle, a combination of rocket
    motors from the Minuteman II and Pegasus XL launch vehicles, is part of an Air
    Force effort to use surplus Minuteman II components for sub-orbital and orbital
    spacelift in support of U.S. Government requirements.  This program is managed
    by the Space and Missile Systems Center Test and Evaluation Directorate located
    at Kirtland AFB, N.M.
    
    The goal of this launch is to validate the OSP Space Launch Vehicle's spacelift
    capability. To determine the mission's success, SMC personnel will evaluate data
    measuring the successful separation of the payloads and detailing whether the
    payloads were deployed in the correct orbit. 
    
    Currently having more than 350 Minuteman II ICBMs in storage, SMC/TE is working
    with the vehicle contractor, Orbital Sciences Corporation, to demonstrate a
    reliable, economical and efficient way to put these missiles to good use.
    
    The OSP Space Launch Vehicle can operate with two fairings allowing for the
    launch of oversized payloads.  Using a multi-payload adapter, the vehicle is
    capable of launching several payloads of up to 750 lbs to a 400-nautical mile,
    sun-synchronous orbit.  This is roughly 1.5 times the Pegasus XL capability.
    
    The payloads for the upcoming launch are integrated to the Joint Air Force
    Academy Weber State University Satellite, or JAWSAT, multi-payload adapter. The
    four payloads are the U.S. Air Force Academy's FalconSat, Arizona State
    University's ASUSAT, Stanford University's OPAL satellite and the Air Force
    Research Laboratory's Optical Calibration Sphere Experiment.
    
    Also attached to the multi-payload adapter are two experiments: NASA Marshall
    Space Flight Center's Plasma Experiment Satellite and Weber State University's
    Attitude Controlled Platform.
    
    Originally set to launch Dec 7, launch officials discovered electrical problems
    during the mission dress rehearsal Dec 1. During this test, the C-BAND
    Transponder, a safety device that notifies operators on the ground that the
    rocket is still on its course, did not respond.
    
    Officials had also discovered at that time that the Modular Avionics Control
    Hardware was not functioning properly. The MACH is a modular interface box,
    which controls telemetry, power transfer and ordnance commands.
    
    After destacking the upper two stages, the Pegasus XL Orion 50 and Orion 38, and
    the fairing, the C-BAND transponder was replaced, and the cause of the MACH
    malfunction was corrected with software modifications.
    
    The second OSP Space Launch Vehicle launch is scheduled for the spring, carrying
    the Air Force Research Laboratory's MightySat II.1 payload.
    
    Spaceport Systems International is under contract to provide launch site and
    launch control facilities as well as range support for both launches. 
    The launch set for Friday will be SSI's first launch.
    
    The Space and Missile Systems Center, located at Los Angeles Air Force Base,
    Calif., is the center of technical excellence for developing and purchasing
    military space systems and manages more than $56 billion in contracts. The
    center has an annual operating budget of more than $5.5 billion and employs
    about 3,400 people worldwide.  For more information, see SMC's web page at
    http://www.laafb.af.mil
    
    The 30th Space Wing, located at Vandenberg AFB, will provide Range support for
    the launch. Range support includes, but is not limited to ensuring safe,
    reliable and timely launch operations in support of DoD and commercial launch
    operations, providing a full range of valuable weather services and control and
    operation of the Western Range for all spacelift and ballistic launches.

    TRW, the OSP Space Launch Vehicle systems engineering and technical assistance
    contractor for Space and Missile Systems Center, will be providing a live web-
    cast and satellite feed of the launch.
