Missions

NSS-8

Mission Profile

A Zenit-3SL launch vehicle will lift the 5,920 kg (13,051 lb.) NSS-8 communications satellite to an optimized geosynchronous transfer orbit (GTO), on its way to a final orbital position of 57 degrees East Longitude.

Two-and-a-half minutes after liftoff, the first stage of the rocket will separate and then the payload fairing will jettison. About eight-and-a-half minutes into the mission, the second stage will separate from the Block DM upper stage. The engine of the Block DM will ignite for a 4-and-a-half-minute burn, after which the spacecraft will enter a coast period of 30 minutes. The Block DM will then ignite for a second burn, for a 7-minute duration and then separate from the spacecraft 10 minutes later, over the Indian Ocean. A ground station in Gnangara, Australia, is expected to acquire the first signal from NSS-8 in orbit, shortly after spacecraft separation.
