    Yeah, the Russians are REALLY good at sticking with what works and making small, incremental changes as they go rather than scrapping stuff every few years and starting over. :rolleyes:

    Did you know that Zenit itself started life as the strap-on booster for the Energia heavy lift vehicle the Soviets used to launch their Buran shuttle (for its one-time only, never-repeated launch, that is)?

    Few steps left:
    • 7:31:10pm ET - Block DM 2nd Burn Ignition
    • 7:38:15pm ET - Block DM 2nd Burn Shutdown
    • 7:48:55pm ET - Spacecraft Separation
    • 12:48am ET - Spacecraft Acquisition (estimated)
    Good Luck!

    "Nominal" is our new favorite word.

    They developed a flight path/plan that would optimize fuel use. Getting there fast isn't as important as getting there efficiently.

    Does the sat. stay at the equator or does it shift to somewhere else eventually?

    They are doing this at the optimal time to insert the satellite into its orbital slot. Right now the vehicle is probably in a very oblong, elliptical orbit. They will time this burn such that at spacecraft separation they are where they need to be in the most fuel-efficient manner.

    It stays equatorial, but it has to be put into the correct longitudinal slot at the proper altitude so that it circles the Earth at the same rate the Earth rotates.
