"Russia intends to eventually withdraw from Baikonur and conduct launches from the Plesetsk Cosmodrome, an operating spaceport about 500 miles north of Moscow ?" and the unfinished Vostochny Cosmodrome in the Russian Far East."
200 miles south of Arkhangelsk? Really?
As one moves further north, one loses the assist from the Earth's rotation. Launch anything easterly from the Equator, and you get slightly more than a 1,000 mile per hour boost to orbit. If you want to save fuel and cost, you try to launch from as far south as you can, which is why we launch from Florida instead of Cape Cod.
(24902 * cos(63))/24
24902=Circumference of the Earth
63=Latitude of the Plestsk Cosmodrome in degrees
24=Hours in a day.
471mph/758kph - it's the worst out of all of them.
Vostochny Cosmodrome is 51 degrees N. 653mph/1051kph
Baikonur is roughly 46 degrees North - 720mph/1160kph
Canaveral is 28.5 (roughly) - 912mph/1468kph
Centre Spatial Guyanais - 5 degrees N. 1034mph 1664kph - the ESA gets the biggest boost.
Unfortunately for the Russians, they don't have anything very far south. The furthest south they can go is the southern end of Dagestan at roughly the same latitude as New York City.
