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)||Jun-01||Jun-02|
|United States of America||2.0||1.6|
|Percentage change from same month previous year||-24.28||-18.48|
