Godspeed DirecTV 11. Enjoy the ride.
Okay, so not much to do until the second burn in about 29 minutes. Whew!
Half hour of coast then second burn Wooha!
250th use of Block DM
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.
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)
"Nominal" is our new favorite word.
hmmm....cool, did not know that....
Hey, why the 30 minute coast ?
Not sure, but it is moving at 10,000 MPH.....
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?
Saves gas and money. Have you seen the prices at the pump lately? !rolling
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.
Thanks.....I was thinking it would be over the US not the equator....stupid me
Why do you think your dish is pointed southwest?
Now doing interviews while waiting for the Block-DM second burn.
I didn't know it was! I'm in an MDU.....so i've never seen the dish. Ha!
