TELSTAR 14 ESTRELA DO SUL

Mission Profile

The Sea Launch team placed the Telstar 14/Estrela do Sul 1 satellite into a high perigee geosynchronous transfer orbit, with the spacecraft separating from the upper stage over the Indian Ocean. Two-and-a-half minutes after liftoff, the first stage of the Zenit-3SL vehicle separated and the payload fairing jettisoned. About six minutes later, the second stage separated from the Block DM-SL upper stage. After the first burn of the Block DM-SL, the spacecraft coasted for 36 minutes. Following this coast period, the Block DM-SL made a second burn and then separated from the spacecraft 10 minutes later. A ground station in Gnangara, Australia, acquired the first signal from the spacecraft 68 minutes after liftoff. This mission used a standard GTO trajectory, which places the payload into a higher energy state. After the payload circularizes itself at geosynchronous orbit altitude, the spacecraft performs a series of maneuvers over several days to place the spacecraft into its final position in geostationary orbit at 63 degrees West Longitude, over Brazil.
