Tonight (Aug 12 2013) is the annual peak of the Perseid meteor shower.
Since meteors are chunks of rock flying through the atmosphere at crazy high speeds, I'm wondering if there are any considerations for the launching of space flights on and around this time - it is generally considered detrimental to have your craft pierced by a flying rock.
Do space agencies take heightened meteor activity around this time into account when planning launches? If so, how?
