Question:

Antares test is being done from Wallops in northern Virginia (not far
from Maryland border).

NASA TV says this is the largest rocket launched from Wallops.

Is this just for the test flight, or do they intend to operate frm that
facility in the long term, despite the more northern latitude bing a
payload disadvantage compared to KSC ?

Or is the difference in latitude small enough that the payload
difference is not significant ?

Actually better for ISS missions.
