Rocket Lab will attempt their first launch from US soil today using their Electron rocket. Launch window is 6:00 to 8:00 pm Eastern. More information and live webcast will be HERE

Thanks.

Do you happen to know how much more it costs to launch there vs somewhere closer to the equator?

Not exactly. There is some loss, as you so astutely observed. The reason (for those less astute) is that at higher latitudes, the eastward rotation of the earth is slower, and at maximum at the equator. A rocket launched from the equator has about 1,000 mph "free" speed boost. The farther north you launch (assuming eastward orbit) the more of that lost initial velocity you have to overcome.

Math is not my forté but I'd guess that a launch from 45 degrees north latitude would sacrifice about half the equatorial boost.

Thank you for the reply...

Economically, it must not be much of a concern. Space is expensive.

Man! Their rocket doesn't even look like a penis.
Bezos wouldn't approve.

Good launch to a good orbit.
