Successful space launches include all military, commercial, and government launches that deliver a payload to the proper orbit and location.
NOTE: The three-month moving average is the average number of successful launches for the most recent month and two preceding months. Launches per month have been adjusted for a 30-day month. The actual number of launches during a month is multiplied by the ratio of 30 to the number of days in that month to yield the adjusted number of launches for that month.
|Successful Space Launches (three-month moving average)||Oct-01||Oct-02|
|United States of America||3.2||1.0|
|Percentage change from same month previous year||24.79||-69.87|
|Percentage change from same month previous year||-55.68||1.24|
