Echostar V satellite launch has been completed, placing the "bird" in the initial low parking orbit. I think it can take then about another week to boost the satellite from low orbit, all the way up to the final geosynchronous orbit at about 24,000 miles up. There is a small rocket engine attached to the satellite to do this job, that engine will be jettisoned later (I think). Here's some data and quotes from the launch history at flatoday.com Update for 2:47 a.m. EDT Contact with the EchoStar-5 satellite has been successfully established this morning following its launch into space by the Lockheed Martin Atlas rocket. Lockheed Martin has provided the orbital data following spacecraft separation, which indicates a very successfully deployment for EchoStar-5. The apogee is 45,822.015 km of the expected 43,848.569 km, a perigee of 166.794 km for a nominal 166.641 km and inclination of 26.5563 degrees for the nominal of 26.5675 degrees. The additional apogee altitude gained should will allow the satellite to save onboard fuel, potentially extending its useful life in space. This will conclude our AC-155/EchoStar-5 Launch Journal. ---------------------------- The nominal orbital parameters for the launch of AC-155 and EchoStar-5 are: Parking orbit: Perigee Altitude: 84 nautical miles Apogee Altitude: 256.5 nautical miles Inclination: 28.2 degrees Spacecraft Nominal Transfer Orbit (just after separation): Perigee Altitude: 90 nautical miles Apogee Altitude: 23,599 nautical miles Inclination: 26.57 degrees "Update for 2:31 a.m. EDT T+plus 29 minutes. SPACECRAFT SEPARATION. The EchoStar-5 satellite has separated from the Centaur upper stage following today's successful launch of the Lockheed Martin Atlas rocket. The launch of AC-155 marks the 44th consecutive success for Atlas rockets dating back to 1993. " ILG
