BY JUSTIN RAY October 2, 2000 -- Follow the countdown and launch of the Proton rocket launching the GE-1A communications satellite for Americom Asia-Pacific. Reload this page for the very latest on the mission.
MONDAY, OCTOBER 2, 2000 The Block DM upper stage was fired twice and later released the Lockheed Martin-built communications satellite, which now begins its early life in space that will include orbital maneuvering and thorough testing before entering commercial service in about a month. Ground controllers have established contact with GE-1A, confirming its health after the launching. The craft will be used by Americom-Asia Pacific -- an endeavor between GE Americom and Lockheed Martin Global Telecommunications -- to provide television and broadband data broadcasting to China, Northeast Asia, the Philippines and India. GE-1A will be parked in geostationary orbit 22,300 miles above the equator at 108.2 degrees East longitude. It carries 28 high-powered Ku-band transponders and has a 15-year life expectancy. The next ILS launch is scheduled for October 12 when an Atlas rocket will loft a military communications satellite for the U.S. Air Force. Proton technicians will keep busy with another commercial ILS launch expected around October 20 carrying the GE-6 communications satellite for GE Americom.
SUNDAY, OCTOBER 1, 2000
2215 GMT (6:15 p.m. EDT) Today's launch is still far from over. The highlights of events yet to come will be a pair of firings by the Block DM. The first is scheduled for T+plus 73 minutes, 49 seconds to raise the altitude from the current circular parking orbit to an egg-shaped loop reaching over 20,000 miles high at one end. After the six-minute firing, the rocket will coast up to that high point before the second burn that will raise the orbit's low end and reduce inclination from the equator. Separation of GE-1A to complete this launch is expected at T+plus 6 hours, 41 minutes and 54 seconds, or 0441 GMT (12:41 a.m. EDT). Check back for confirmation of spacecraft separation later tonight.

2200 GMT (6:00 p.m. EDT)
2159 GMT (5:59 p.m. EDT) The engine start command will be issued by the launch sequencer at T-minus 2.5 seconds. The six first stage engines will be ignited at T-minus 1.6 seconds and commanded to 40 percent thrust. The thrust level is then increased to 100 percent at T-0 seconds. The liftoff confirmation is expected at T+0.57 seconds. This engine start sequence allows for verification that all six powerplants are running normally before committing the Proton to launch.

2145 GMT (5:45 p.m. EDT)
2140 GMT (5:40 p.m. EDT) The Proton rocket's first three stages that make up the core vehicle will complete their mission during the first 9 minutes, 49 seconds of the launch. The Proton third stage will deploy the Block DM upper stage and attached GE-1A spacecraft into a 116 nautical mile circular parking orbit. The Block DM will conduct the first of two firings at T+plus 73 minutes, 49 seconds to begin the journey into the desired orbit for GE-1A. The burn will last about six minutes. A second burn is planned at T+plus 6 hours, 20 minutes, 4 seconds to completed the powered phase of today's launch. The second Block DM firing is expected to last just under two minutes. Separation of GE-1A from the Block DM will occur 6 hours, 41 minutes, 54 seconds after liftoff.
2135 GMT (5:35 p.m. EDT)
2128 GMT (5:28 p.m. EDT) The four stages that make up the rocket have been fully fueled for today's mission, which is managed by International Launch Services. Loading of propellants began about six hours ago. The countdown is now under computer sequencer control through the remaining time until launch. Also, the launch team has provided the final updates to the rocket's guidance computer.
0401 GMT (12:01 a.m. EDT) Spaceflight Now will provide live updates in the final 40 minutes or so of the countdown and the launch. We will also provide a QuickTime streaming video broadcast.
FRIDAY, SEPTEMBER 29, 2000 Liftoff is scheduled for 2200 GMT (6 p.m. EDT) from pad 23 of Launch Complex 81 of the Baikonur Cosmodrome in Kazakhstan. The available launch window extends about 10 minutes. This satellite-delivery mission will be managed under the auspices of International Launch Services -- the U.S./Russian venture that globally markets Proton and Atlas rockets. This will be ILS' 17th Proton launch since 1996. Proton's three stages will fire for the first 10 minutes of the launch, deploying the Block DM upper stage and attached GE-1A satellite into a parking orbit 116-nautical miles above Earth. The Block DM will later fire two times to propel the satellite cargo into an orbit with a high point of 20,870 nautical miles, low point of 90 nautical miles and inclined 26.46 degrees to the equator. Spacecraft separation from the upper stage to complete the launch is expected six-hours, 41 minutes into flight. In the days following the launch, GE-1A will fire its own kick motor to arrive in circular geostationary orbit, parking at 108 degrees East longitude. The broadcasting satellite, built by Lockheed Martin Space Systems, will provide direct-to-home television and broadband data network services to China, Northeast Asia, the Philippines and India. The 7,831-pound craft carries a payload of 28 Ku-band transponders on three beams that will allow 8 to 16 to cover Greater China, 8 to 16 to cover Northeast Asia/Philippines and up to 8 for South Asia. Spaceflight Now will provide continuous live status reports during Sunday's final countdown and launch here on this page. In addition, we will offer a live QuickTime streaming video broadcast starting at 2120 GMT (5:20 p.m. EDT).
